ASTRONOMER HAR SET ET SORT HUL OPSLUGE EN NEUTRON-STJERNE: Astronomers were finally able to detect a merger between a black hole and a neutron star. This phenomenon was predicted before, but just recently observed by detecting gravitational waves that were made in the merger. The unique thing about this is that instead of merging between 2 objects it could be more precise to say that tHe black hole "swallowed" the neutron star.
DISKUSSION OM HVOR HURTIGT UNIVERSET UDVIDER SIG: Our universe is expanding, but our two main ways to measure how fast this expansion is happening have resulted in different answers. For the past decade, astrophysicists have been gradually dividing into two camps: one that believes that the difference is significant, and another that thinks it could be due to errors in measurement.
ASTRONOMISK KOLLISION MELLEM TO HVIDE DVÆRGE: Astronomers have discovered the smallest and most massive white dwarf ever seen. The smoldering cinder, which formed when two less massive white dwarfs merged, is heavy, "packing a mass greater than that of our Sun into a body about the size of our Moon," says Ilaria Caiazzo, the Sherman Fairchild Postdoctoral Scholar Research Associate in Theoretical Astrophysics at Caltech and lead author of the

CENP-A, a centromere-specific histone H3 variant, establishes the foundations for centromere epigenetic memory and kinetochore assembly. It recruits the constitutive centromere-associated network (CCAN), which in turn assembles the microtubule-binding i
While androgen-targeted therapies are routinely used in advanced prostate cancer (PCa), their effect is poorly understood in treating bone metastatic lesions and ultimately results in the development of metastatic castrate resistant prostate cancer (mCRPC). Here, we used an all-human microtissue-engineered model of mineralized metastatic tissue combining human osteoprogenitor cells, 3D printing a
We developed a unified dynamic model to explain how cellular anisotropy and plasticity, induced by alignment and severing/rebundling of actin filaments, dictate the elongation dynamics of Caenorhabditis elegans embryos. It was found that the gradual alignment of F-actins must be synchronized with the development of intracellular forces for the embryo to elongate, which is then further sustained b
Second sound is known as the thermal transport regime where heat is carried by temperature waves. Its experimental observation was previously restricted to a small number of materials, usually in rather narrow temperature windows. We show that it is possible to overcome these limitations by driving the system with a rapidly varying temperature field. High-frequency second sound is demonstrated in
The strength of nanocrystalline and nanotwinned metals stops increasing or even starts decreasing when their grain size or twin thickness is below a critical size—a phenomenon known as Hall-Petch breakdown—which hinders the attainment of ultrahigh strength. Here, we report continuous strengthening in nanotwinned pure Ni with twin thicknesses ranging from 81.0 to 2.9 nm. An unprecedented strength
Chirality plays a key role in the physiological system, because molecular functionalities may drastically alter due to a change in chirality. We report herein a unique color indicator with a static helicity memory, which exhibits visible color changes in response to the chirality of chiral amines. A difference of less than 2% in the enantiomeric excess (ee) values causes a change in the absorptio
Charge order is universal to all hole-doped cuprates. Yet, the driving interactions remain an unsolved problem. Electron-electron interaction is widely believed to be essential, whereas the role of electron-phonon interaction is unclear. We report an ultrahigh-resolution resonant inelastic x-ray scattering (RIXS) study of the in-plane bond-stretching phonon mode in stripe-ordered cuprate La 1.675
Electronic skins (e-skins)—electronic sensors mechanically compliant to human skin—have long been developed as an ideal electronic platform for noninvasive human health monitoring. For reliable physical health monitoring, the interface between the e-skin and human skin must be conformal and intact consistently. However, conventional e-skins cannot perfectly permeate sweat in normal day-to-day act
Soft-bodied locomotion in fluid-filled confined spaces is critical for future wireless medical robots operating inside vessels, tubes, channels, and cavities of the human body, which are filled with stagnant or flowing biological fluids. However, the active soft-bodied locomotion is challenging to achieve when the robot size is comparable with the cross-sectional dimension of these confined space
Nonrecombining sex chromosomes, like the mammalian Y, often lose genes and accumulate transposable elements, a process termed degeneration. The correlation between suppressed recombination and degeneration is clear in animal XY systems, but the absence of recombination is confounded with other asymmetries between the X and Y. In contrast, UV sex chromosomes, like those found in bryophytes, experi
The global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) necessitates the rapid development of new therapies against coronavirus disease 2019 (COVID-19) infection. Here, we present the identification of 200 approved drugs, appropriate for repurposing against COVID-19. We constructed a SARS-CoV-2–induced protein network, based on disease signatures defined by COVID-19 mu
Because of its small size (70 kilodalton) and large content of structural disorder (>50%), the human growth hormone receptor (hGHR) falls between the cracks of conventional high-resolution structural biology methods. Here, we study the structure of the full-length hGHR in nanodiscs with small-angle x-ray scattering (SAXS) as the foundation. We develop an approach that combines SAXS, x-ray diffrac
Retromer, a cellular protein trafficking complex, sorts human papillomaviruses (HPVs) into the retrograde pathway for transport of HPV to the nucleus during virus entry. Here, we conducted a protein modulation screen to isolate four artificial transmembrane proteins called traptamers that inhibit different steps of HPV entry. By analyzing cells expressing pairs of traptamers, we ordered the traff
Language distinguishes us humans; we learn it through experience and social interactions. Especially in the first year of life, human vocalizations change dramatically, becoming more and more language-like. In our closest relatives, non-human primates, language development was previously thought to be largely predetermined and completed within the first few weeks after birth. In a behavioral study
A study published in Science Advances reports on the unexpected observation of thermal waves in germanium, a semiconductor material, for the first time. This phenomenon may allow a significant improvement in the performance of our electronic devices in a near future. The study is led by researchers from the Institute of Materials Science of Barcelona (ICMAB, CSIC) in collaboration with researchers
The Bronze Age in the eastern Mediterranean has long been considered by researchers to have been the 'first international age,' especially the period from 1600-1200 BC, when powerful empires from Anatolia, Mesopotamia, and Egypt set up large networks of subordinate client kingdoms in the Near East. These empires fought, traded, and corresponded with one another, and ancient texts from the period r
A city's street names can provide a glimpse into its cultural value system and a way to quantify cultural indicators, according to a study published June 30, 2021 in the open-access journal PLOS ONE by Melanie Bancilhon from Washington University in Saint Louis, U.S., and colleagues.
Growing resistance to our go-to antibiotics is one of the biggest threats the world faces. As common bacteria like strep and salmonella become resistant to medications, what used to be easily treatable infections can now pose difficult medical challenges.
New research clarifies how hot nights are curbing crop yields for rice. “Essentially, we found that warmer nights throw the rice plant’s internal clock out of whack,” says Colleen Doherty, an associate professor of biochemistry at North Carolina State University and corresponding author of a paper on the work in the journal PNAS . “Most people think plants aren’t dynamic, but they are. Plants are
The chance of detecting the virus that causes COVID-19 increases with more frequent testing, no matter the type of test, a new study found. Both polymerase chain reaction and antigen tests, paired with rapid results reporting, can achieve 98 percent sensitivity if deployed at least every three days.
The new technology, enabling the storage of information in the thinnest unit known to science, is expected to improve future electronic devices in terms of density, speed, and efficiency. The allowed quantum-mechanical electron tunneling through the atomically thin film may boost the information reading process much beyond current technologies. The technology involves laterally sliding one-atom-th
The Titanic is disappearing. The iconic ocean liner that was sunk by an iceberg is now slowly succumbing to metal-eating bacteria: holes pervade the wreckage, the crow's nest is already gone and the railing of the ship's iconic bow could collapse at any time.
Marin samodling med musslor kan göra att tång växer bättre och blir mer tålig för klimatförändringar, visar studier från Göteborgs universitet. Övervägande delen av matproduktionen i världen sker med monokultur, alltså att bara en art odlas, som till exempel vete på land, eller uppfödning av lax i havsvatten. Dessa system är produktiva men kan ha stor påverkan på miljön. I stället för att bara od
Pick up any product in just about any store and you're likely to find information that indicates the country of origin of the product. The U.S. Federal Trade Commission (FTC) requires this for any imported product, but not for products made in the United States. When you see the words "Made in U.S." on a product, it's purely for marketing purposes. So, does it work?
GSA's dynamic online journal, Geosphere, posts articles online regularly. Locations and topics studied this month include the central Appalachian Mountains; fossil pollen in Colombia; the precision and accuracy of model analyses; the Bone Spring Formation, Permian Basin, west Texas; and the geochronology of modern river sediment in south-central Alaska.

Leveling up access to finance so that poorer countries can afford the funds needed to switch to renewable energy could see regions like Africa reaching net zero emissions a decade earlier, according to a study led by UCL researchers.
Researchers at the National Institute of Standards and Technology (NIST) have upgraded their laser frequency-comb instrument to simultaneously measure three airborne greenhouse gasses—nitrous oxide, carbon dioxide and water vapor—plus the major air pollutants ozone and carbon monoxide.
A McGill-led study has shown that the size of the Maya population in the lowland city of Itzan (in present-day Guatemala) varied over time in response to climate change. The findings, published recently in Quaternary Science Reviews, show that both droughts and very wet periods led to important population declines.
Increasing our understanding of cellular processes requires information about the types of biomolecules involved, their locations, and their interactions. This requires the molecules to be labeled without affecting physiological processes (bioorthogonality). This works when the markers are very quickly and selectively coupled using small molecules and 'click chemistry'. In the journal Angewandte C
Plants play an essential role in curbing climate change, absorbing about one-third of the carbon dioxide emitted from human activities and storing it in soil so it doesn't become a heat-trapping gas. Extreme weather affects this ecosystem service, but when it comes to understanding carbon uptake, floods are studied far less than droughts—and they may be just as important, according to new research
Growing in popularity, unagi kabayaki—grilled freshwater eel in soy sauce—can be found on the menu of many Japanese restaurants, and is stocked by Asian shops and in specialist supermarkets. But new research tracing the DNA of eel filets used for this dish has found that fraudulent food labeling is rife, with a third of the products violating EU regulations on the provision of food information. Wi
By the beginning of April 2021, the number of people infected during the COVID-19 pandemic had risen to more than 130 million people of whom more than 2.8 million died. The SARS-CoV-2 virus responsible for COVID-19 is transmitted particularly by droplets or aerosols emitted when an infected person speaks, sneezes or coughs. This is how the viruses and other pathogens spread through the environment
Politicians use emotional resources in their speeches in parliament depending on the type of debate and use emotive rhetoric strategically and selectively, mainly to attract voters. This is one of the main conclusions of a study published in the journal American Political Science Review (APSR) involving Toni Rodon, a professor with the UPF Department of Political and Social Sciences and member of
Believe it or not, steel has something in common with bacterial appendages: they can both undergo a special type of physical transformation that remains puzzling. Now, researchers from Japan and China have used direct microscopic observations to provide more clarity to how this transformation occurs.
Making certain fruit flies, Drosophila suzukii , produce only male offspring could protect soft-skinned fruit crops, research indicates. D. suzukii , also called “spotted-wing drosophila” are modified with a female-lethal gene that uses a common antibiotic as an off switch. Withholding the antibiotic tetracycline in the diet of larvae essentially eliminates birth of female D. suzukii flies as the
Malcom Gladwell's new book The Bomber Mafia traces the stories of major personalities during WWII as bombing tactics developed. Of particular interest to him were the men who dreamed of precision bombing as a way to make war quick, efficient, and far less deadly. He concludes that the Bomber Mafia was ahead of its time. Humanity has always had the odd idea that one tactical change or new technolo
Spatial reasoning ability in small children reflects how well they will perform in mathematics later. Researchers from the University of Basel recently came to this conclusion, making the case for better cultivation of spatial reasoning.
Decision-makers around the world are increasingly interested in using ecosystem solutions such as mangroves, coral reefs, sand dunes and forests on steep slopes to help buffer the impacts from hazard events and protect populations. But what evidence exists to show the efficacy of nature-based solutions over man-made protective measures to reduce the impacts of the increasing numbers of hazard even
When it comes to climate change, not all organisms will lose out. A new study finds that rattlesnakes are likely to benefit from a warming climate. A combination of factors makes a warming climate beneficial to rattlesnakes that are found in almost every part of the continental United States but are especially common in the Southwest.
Fossilized feces are common finds at paleontological dig sites and might actually contain hidden treasures. By scanning fossilized dung assigned to a close dinosaur relative from the Triassic period, scientists discovered a 230-million-year-old beetle species, representing a new family of beetles, previously unknown to science. The beetles were preserved in a 3D state with their legs and antennae
A stocky marsh bird with a 20-inch wingspan, great snipes are also speedy marathoners that can migrate from Sweden to Central Africa in just three days, without stopping to eat, drink, or sleep. Now, researchers find that snipes also rise nearly 2,500 meters in elevation at dawn and descend again at dusk each day, perhaps to avoid overheating from daytime solar radiation by climbing higher.
Two U.S. Phase 1 clinical trials of a novel candidate malaria vaccine have found that the regimen conferred unprecedentedly high levels of durable protection when volunteers were later exposed to disease-causing malaria parasites. The vaccine combines live parasites with either of two widely used antimalarial drugs — an approach termed chemoprophylaxis vaccination. A Phase 2 clinical trial of the
On June 16, the Federal Reserve announced it may raise interest rates twice in 2023 in response to higher-than-expected increases in inflation. In his announcement, Fed Chairman Jerome Powell said the higher inflation recorded this year should be temporary, but the risks that it would be “higher and more persistent than we expect” could not be ignored. John Horn, professor of practice in economic

When it comes to understanding and predicting trends in energy use, the internet is a tough nut to crack. So say energy researchers Eric Masanet, of UC Santa Barbara, and Jonathan Koomey, of Koomey Analytics. The two just published a peer-reviewed commentary in the journal Joule discussing the pitfalls that plague estimates of the internet's energy and carbon impacts.
Tests performed by Brazilian researchers after the first 16 weeks of COVID-19-induced confinement showed loss of muscle strength and diminished aerobic capacity, as well as an increase in cholesterol and glycated hemoglobin, both of which are risk factors for metabolic disorders.
Following habitat-destroying wildfires, researchers found many male red-backed fairywrens failed to molt into their ornamental plumage, making them less attractive to potential mates. They also had lowered circulating testosterone, which has been associated with their showy feathers. The birds' fat stores and stress hormone corticosterone remained at normal levels. While the findings are specific
The study finds that higher polygenetic scores for schizophrenia, depression, neuroticism, self-reported risk-taking, a high body mass index, alcohol use disorder, along with a higher number of cigarettes smoked per day were all indicators of a higher risk for nicotine dependence.
Newly published research shows that a screening program in the University of Cincinnati Medical Center Emergency Department helped detect an outbreak of HIV among persons who inject drugs in Hamilton County, Ohio, from 2014-18.

Since the onset of the COVID-19 pandemic last year, medical experts have stressed the importance of having a plan in the event of a positive test result. A new study by University of Houston psychologists reveals 96% of healthy, educated adults did not have a comprehensive plan in mind.
Not all astronauts start off as test pilots. I spoke with David Saint-Jacques, a Canadian astronaut with a medical degree who’s spent 203 days aboard the ISS, and learned some of the career twists and turns one can take on the way into orbit. Most people would think being an engineer and astrophysicist is enough. You also earned a medical degree—and then topped that by becoming an astronaut. What
A new Finnish study shows that 180 health care workers who had received two doses of the Pfizer and Biontech vaccine have very good antibody responses against the SARS-CoV-2 virus. The immune response was as strong against the alpha variant (formerly the UK variant) but was somewhat decreased against the beta variant (formerly the South Africa variant).

Using high-performance computation systems, a Universitat Rovira i Virgili research team (Tarragona-Spain) has simulated the flow of air produced by coughing and sneezing in unprecedented detail. The results give greater insight into the characteristics of the flow produced by breathing and the capacity of infectious aerosols to disperse in the environment and remain suspended, which spreads COVID
Malaria still kills millions. Researchers are excited by a new intervention: giving people a drug which kills mosquitoes that bite them. Incredibly, this is a reality, as the drug ivermectin, widely used for the control of parasite infections such as lymphatic filariasis and onchocerciasis, appears to do this. With some mosquitoes now resistant to the insecticides used in treated bed nets, this is
Dire Situation As the horrific, record-shattering heatwave continues in western Canada and the northwest United States, a disturbing death toll is starting to climb. Officials in the Vancouver area told the BBC that the intense heat has contributed to about 130 sudden deaths between Friday and Wednesday. A dozen more occurred in Portland, Oregon and Seattle since the heatwave began — illustrating
Researchers from The University of Tokyo Institute of Industrial Science and Fudan University experimentally confirmed three previously unknown phase transition phenomena in soft colloidal crystals. Knowledge of such phenomena will be useful for imparting new properties to materials without altering their chemical composition.
Results of a new study led by researchers at Boston Medical Center (BMC) show, however, that this expansion did not lead patients receiving care at safety-net hospitals to transfer their care to non-safety-net hospitals.
What The Study Did: This survey study investigated the association between general surgery resident grit, which was defined as perseverance and passion for long-term goals, and burnout and thoughts of attrition and suicide.
What The Study Did: Researchers in this randomized clinical trial found that a large proportion of patients who canceled visits and procedures early in the COVID-19 pandemic didn't reschedule once reopening occurred.
What The Study Did: This crossover trial found that perceived breathing resistance at peak exercise is uniquely and significantly elevated when exercise stress testing (EST) is performed while wearing a mask. Performing EST with a mask yielded lower peak exercise oxygen uptake and heart rates as compared with no mask.
Neuroscientists at UCL have, for the first time, identified abnormalities in the way memories are 'replayed' in the brains of people with schizophrenia; researchers say the pathbreaking study provides an entirely new basis for explaining many of the condition's core symptoms.
MIT neuroscientists have uncovered a common neural mechanism for cognitive impairments seen in some people with autism and schizophrenia, even though the genetic variations that produce the impairments are different for each disorder.
In an article published today in Nature, Sanaria's PfSPZ-CVac (CQ) vaccine is reported as being safe and protecting 100% of six subjects against a variant malaria parasite three months after their last dose in the company's Phase 1 safety and efficacy trial. This is the first time complete protection against a variant malaria parasite has ever been achieved that long after vaccine administration.
Harpy eagles (Harpia harpyja) – which are among the world's largest eagle species – struggle to feed offspring in heavily deforested areas of the Amazon, according to a study published in Scientific Reports.
The tiny beetle Triamyxa coprolithica is the first-ever insect to be described from fossil feces. The animal the researchers have to thank for the excellent preservation was probably the dinosaur ancestor Silesaurus opolensis, which 230 million years ago ingested the small beetle in large numbers.

How close have you ever gotten to a wild bird? Can you remember the details of its plumage or the curvature of its beak? Did it sit in one place long enough for you to really study all of its colors and other characteristics? Probably not—at least if it was alive. The avid birders among us sometimes search their whole life for a glimpse of a particularly rare species. But if you are just a casual
In a forthcoming article in the Michigan Journal of Race & Law, Raymond Magsaysay explores the multifaceted problem of Asian Americans and Pacific Islanders (AAPIs) being largely left out of recent conversations about overhauling the criminal justice system to address racial injustice. The selection of Magsaysay's article for publication is a distinguished honor as law students rarely have the opp
On June 25, 2021, the Pentagon released a much-anticipated report on UFOs to Congress. The military has rebranded unidentified flying objects as unidentified aerial phenomena –UAPs—in part to avoid the stigma that has been attached to claims of aliens visiting the Earth since the Roswell incident in 1947. The report presents no convincing evidence that alien spacecraft have been spotted, but some
When people think of rodents, they usually think of introduced species such as the black rat and house mouse. But Australia actually has around 54 native rodent species, which live in a vast range of habitats across the continent, from the ocean to spinifex-dotted deserts.
Research conducted at the SCI by Mariel Vilella, Director of Global Strategy at Zero Waste Europe, in collaboration with the Global Alliance for Incinerator Alternatives and Break Free From Plastic, looks at examples of successful business models that are successfully contributing to the reduction of single-use plastic consumption, exploring their impact and the key conditions for their replicatio
Four leading medical specialty societies released a new clinical practice guideline that includes recommendations for reducing blood loss during heart surgery and improving patient outcomes.

A new study in the Journal of the American Heart Association shows that a breathing exercise known as Inspiratory Muscle Strength Training can reduce blood pressure in weeks, with benefits on par with daily exercise or medication.
Despite being the leading country when it comes to transparency, public accessibility and free availability of fisheries data, the United States of America's lack of international reporting of recreational catches and fish discarded at sea may hinder proper ecosystem-based management efforts, new research has found.
This illustration depicts a planet partially hidden in the glare of its host star and a nearby companion star. After examining a number of binary stars, astronomers have concluded that Earth-sized planets in many two-star systems might be going unnoticed by transit searches, which look for changes in the light from a star when a planet passes in front of it. The light from the second star makes i
Forskare på Chalmers har tagit fram en metod för att märka mRNA-molekyler och följa dess väg i cellerna, med blotta ögat i ett mikroskop och i realtid – utan att påverka mRNAts naturliga funktion. Genombrottet gör det lättare att utveckla nya RNA-baserade mediciner. Medicinska terapier baserade på RNA kan ge möjligheter att förebygga, behandla och potentiellt bota sjukdomar. Utmaningen är att lev
Wine grapes are particularly finicky when it comes to their environment. For instance, heatwaves and droughts lead to earlier berry ripening and lackluster wine. And these types of episodes are expected to intensify as Earth's climate changes. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have tweaked growing conditions for Cabernet Sauvignon grapes to slow down the
Worldwide, 267 million people live on land less than two meters above sea level, which is most at risk from sea level rise, according to a study in Nature Communications. The paper suggests that by 2100 the number could increase to 410 million people, with the majority of this land found in the tropics.
QUT researchers have developed a new machine learning mathematical system that helps to identify and detect changes in biodiversity, including land clearing, when satellite imagery is obstructed by clouds.

October 1967 From “How I Stopped Worrying and Learned to Live with Irrationality”: Whatever form it takes, resistance to any change is essentially an act of self-protection. When an individual perceives that the consequences of a change conflict with his needs and desires, he will become anxious and fear for his future. … Whether or not the circumstances justify such response is irrelevant. What
Climate change is warping geological time, compressing the time scales of natural processes. In photographs taken around the world, Ian van Coller has documented these shifts, reflected in rocks, sediment, and the shrinking of glaciers. Van Coller collaborates with scientists who annotate his images, pointing out key geological features. He also uses historical photos to show changes, juxtaposing
In 2017, MIT Technology Review honored Tracy Chou as one of our 35 Innovators Under 35. At the time, Chou was working to expose Silicon Valley’s diversity issues. As an engineer at Pinterest, she’d published a widely circulated blog post calling for tech companies to share data on how many women worked on their engineering teams. She collected their responses in a public database that revealed ho
Though we’ve called it the “Change” issue, this edition of the magazine is really about two things: reflection and empowerment. For far too many of us, the pandemic has been a study in feeling powerless, and we’ve had little time to reflect as we focus on keeping ourselves and our loved ones safe, employed, and as mentally sound as possible. We’ve been forced to cope almost constantly with the tw
One day in late March, People’s Daily , the Chinese Communist Party’s official newspaper, shared a pair of photos on Chinese social media. The first, in black and white, was of the signing of the Boxer Protocol, a 1901 treaty between the Qing empire, which ruled China at the time, and 11 foreign nations. Troops from eight of these countries, including the US, had occupied Beijing following sieges
In late 2007, less than 10 years into the company’s existence, Google came out swinging on the clean energy front. To a fanfare of plaudits up and down Silicon Valley and well beyond, it declared “RE : make renewable energy cheaper than coal. The company invested tens of millions of dollars into R&D efforts from concentrated solar power to hydrothermal drilling. Four years later, those efforts ha
For Apple, Amazon, Facebook, and Alphabet, covid-19 was an economic blessing . Even as the pandemic sent the global economy into a deep recession and cratered most companies’ profits, these companies—often referred to as the “Big Four” of technology —not only survived but thrived. Collectively, they now have annual revenue of well over a trillion dollars, and the value of their stocks has soared:
The workers at the Amazon fulfillment center in Bessemer, Alabama, wanted a union . The center opened in March of last year, just as stay-at-home orders for covid-19 went into effect. While much of the world economy tanked, some sectors thrived, including tech—Amazon founder Jeff Bezos would add some $75 billion to his own net worth in 2020. Back at Bessemer, though, workers were being pressed to
A year into the covid-19 pandemic, Apple commemorated the growing array of devices featuring its custom M1 chip with great fanfare, including a “Mission Implausible” ad on TV featuring a young man running across the rooftops of its “spaceship” campus in Cupertino and infiltrating the facility to “steal” the breakthrough microprocessor from a MacBook and place it inside an iPad Pro. Apple’s custom
Flushable wipes might feel good, but they’re terrible for the environment. Despite the name, they can overwhelm sewer systems and bind together into enormous clogs that can block the sewers for entire cities. Pristine toilet paper spray gives you all of the advantages of a flushable wipe, while keeping the lower cost, and disposability, of toilet paper. If you’re a Shark Tank fan, you already kno
Because Earth’s magnetic fields are able to protect us from much of the radiation that barrels through space, humans on this planet aren’t exposed to much of it—only about 3 to 4 millisieverts (mSv) every year. An astronaut staying on the International Space Station for 180 days, on the other hand, would get hit by 50 to 180 mSv. How that affects you depends on many different factors, including g
Using data originally gathered for spacecraft 'housekeeping' aboard ESA's Rosetta and Mars Express missions, scientists have revealed how intense bursts of high-energy radiation, known as cosmic rays, behave at Mars and throughout the inner solar system.
Oxford University Scientist Dr. Chris Thorogood from Oxford Botanic Garden teamed up with Siti-Munirah at the Forest Research Institute Malaysia, and local explorer Dome Nikong to describe a strange plant from the depths of the Malaysian rainforest.
Extraordinary heat events occur around the planet during most summers, but the current heatwave in the Pacific Northwest is truly exceptional.

Att tro att alla äldre människor är teknikfientliga är ålderism och stämmer inte med sanningen. Risken för att hamna i digitalt utanförskap handlar inte främst om ålder – utan snarare om ekonomi, kunskap och socialt nätverk. Det visar en studie där forskare har följt 3000 personer i ålderspannen 30–39, 50–59 och 70–79 år under pandemin. Fokus har legat på deras attityder till och användning av di

But for the 1,340 students who got good news from MIT on Pi Day, coming to Cambridge for the usual Campus Preview Weekend (CPW) was off the table. Instead, the Admissions Office invited them to CP*, a monthlong series of virtual events, and sent them a box of MIT love. It i
Last May, when we issued our Climate Action Plan for the Decade , we were mobilizing MIT to take on the climate problem as never before. The complexity and uncertainty of climate change make tackling it much more than a “moonshot.” Getting humans to the moon was difficult. But it was a well-defined problem with a solution based on established science, with no opposing forces other than a few law
Which is more powerful: the urge for sex or the instinct to stay away from someone who’s sick? A new study suggests that at least in mice, it’s the latter. Researchers in the lab of Gloria Choi, an associate professor of brain and cognitive sciences at MIT and a member of the Picower Institute for Learning and Memory, found that when male mice encountered a female mouse showing signs of illness,

Early detection is key to surviving melanoma, a type of malignant tumor responsible for more than 70% of skin-cancer-related deaths worldwide, but “suspicious pigmented skin lesions” (SPLs) are so common it’s impractical for doctors to check them all out. Now MIT researchers have developed a tool that can analyze skin photos taken with a smartphone to determine which SPLs should be evaluated by a
When water used in many industrial systems evaporates, salts and other dissolved minerals can be left behind on component surfaces, where they eventually degrade equipment, block pipes, and reduce the efficiency of important heat exchange processes. Now MIT researchers have discovered a phenomenon that could help solve this problem while potentially turning the contaminants into useful products—a
In April, thanks to an MIT-designed instrument, NASA’s Mars rover Perseverance achieved a remarkable milestone: it generated the first breathable oxygen on another planet. The Martian atmosphere is about 95% carbon dioxide, but MOXIE (Mars Oxygen In-situ Resource Utilization Experiment), a small box-shaped device on board, converted it to oxygen through a technique called solid oxide electrolysis
City planners have standard methods of estimating the car traffic that a project is likely to generate, but they have no equivalent for foot traffic.

Worried about aging ? That’s totally understandable. Nobody wants to get old. However, that doesn’t mean you should try to fight it. A lot of people waste their money on health, wellness, and beauty products that claim to “stop” or “defy” or even “reverse” the “signs” of aging. But in reality all of those things are impossible. And even if they weren’t impossible, aging isn’t just about what you
