Is there anyone out there? This is an age-old question that researchers have now shed new light on with a study that calculates there could be more than 30 intelligent civilizations throughout our Galaxy. This is an enormous advance over previous estimates which spanned from zero to billions.
New research by University of Delaware doctoral student Zhangxian Ouyang and oceanographer Wei-Jun Cai, and an international team of researchers, demonstrates that rapid warming and sea-ice loss have induced major changes in the western Arctic Ocean.
Imagine Earth completely covered in ice. While it's hard to picture all of today's oceans and land masses obscured with glaciers, such an ice-covered version of the planet was not so far-fetched millions of years ago.
A mouse study by Craig Powell, M.D., Ph.D., and colleagues suggests that early genetic rescue may be a potential therapy in autism spectrum disorder, or ASD. Powell looked at one gene called SHANK3, whose alteration is seen in about 0.5 percent of ASD patients.
Ice melts in the Arctic Ocean were thought to be drawing large amounts of carbon dioxide out of the atmosphere, acting as a carbon sink and helping to mitigate greenhouse gases. But new research from the University of Delaware shows that may not be the case in all areas, particularly in the Canada Basin, where the carbon sink is shrinking, inhibiting the ocean's ability to absorb carbon dioxide fr
A research team led by Prof. JIANG Ling and Prof. YANG Xueming from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences, in collaboration with Prof. LI Jun from Tsinghua University, has now revealed that the noncyclic 3D structure of water clusters begins to exist with pentamers at low finite temperatures.
When we cut our fingers, blood rushes out of the wound to close it. However, the vegetable, we just wanted to slice and dice, would have reacted utterly different to this injury. Scientists at the Institute of Science and Technology Austria (IST Austria) investigated how plant cells heal wounds. In their results, published in PNAS on June 15, the researchers discovered that the hormone Auxin and p

With or without a new GCSE, pupils must be taught to think about life on Earth The lockdown edition of the BBC’s Springwatch ended on Friday, with a series of clips sent in by viewers to illustrate their wildlife enthusiasms. But the latest stage in a campaign to extend the reach of natural history beyond television schedules has only just begun. The idea for a new GCSE in the subject came from t
How could the planet be covered entirely in ice — a state known as 'Snowball Earth'– and still give rise to multicellular life? The transition to such icy periods may not have been as abrupt as previously thought, new research shows.
Scientists have developed molecules that can remodel the bacterial population of intestines to a healthier state. They also have shown — through experiments in mice — that this approach reduces cholesterol levels and strongly inhibits the thickened-artery condition known as atherosclerosis.
Scientists have demonstrated a practical technique for controlling magnons, which could lead to computer chip switches that would use less energy and radiate less heat. The approach brings two important firsts: It can be built on silicon and operates efficiently at room temperature, meaning it might be more readily employed by computer manufacturers.
A tuberculosis vaccine developed 100 years ago also makes vaccinated persons less susceptible to other infections. While this effect has been recognized for a long time, it is not known what causes it.
The brain and its surrounding blood vessels exist in a close relationship. Researchers have discovered how cells of the blood vessels sense the metabolic condition of the brain and alter vascular function in response. The result could be important for patients with neurodegenerative disorders such as Alzheimer's because the onset of these age-related diseases coincides with vascular defects and br
Light exerts a certain amount of pressure onto a body: sun sails could thus power space probes in the future. However, when light particles (photons) hit an individual molecule and knock out an electron, the molecule flies toward the light source. Atomic physicists have now observed this for the first time, confirming a 90 year-old theory.
The group that previously studied Martian dust storms now shifts focus to the electrochemical processes resulting from dust storms that may power the movement of chlorine, which is ongoing on Mars today.
Many of us have seen informational posters at parks or aquariums specifying how long plastics bags, bottles, and other products last in the environment. They're a good reminder to not litter, but where does the information on the lifetime expectancy of plastic goods come from, and how reliable is it?

Many serious diseases, including autism, schizophrenia and numerous cardiac disorders, are believed to result from mutation of an individual's DNA. But some large mutations, which still make up only a small fraction of the total human genome, have been surprisingly challenging to detect.
Weights to carry around with you. (Alora Griffiths via Unsplash/) The history of the kettlebell stretches all the way back to 18th-century Russia, where large round metal balls called girya were used to counterbalance crops to determine their weight. They were later adopted by circus strongmen as a means of proving their merit before eventually being adopted into weight lifting training, as well
Scientists have identified a green glow in the atmosphere of Mars caused by sunlight releasing oxygen atoms from carbon dioxide — the first time such a glow has been observed on a planet other than Earth. As oxygen is abundant in Earth’s atmosphere, a similar one can be observed from the International Space Station . It’s the same effect that gives auroras their green hue. “One of the brightest e

New research documents the often tense relationship between homicide detectives and the friends and families of murder victims. Criminologists Mark Reed and Dean Dabney collected data from homicide detectives in a single metropolitan unit by accompanying them during an eight-hour shift, recording notes, and conducting on-site interviews. They interviewed the victims’ families and friends in focus
Michael Flor, a COVID-19 survivor who holds the unfortunate record for the longest hospital stay linked to the pandemic, just got nailed with the bill. And in a horrifying indictment of the for-profit U.S. healthcare system, the hospital charged more than $1 million for his treatment. The 181-page itemized bill — that’s longer than Joseph Conrad’s “Heart of Darkness” — comes to a total of $1,122,
The number of human tuberculosis (TB) cases that are due to transmission from animals, as opposed to human-to-human transmission, may be much higher than previously estimated, according to an international team of researchers. The results could have implications for epidemiological studies and public health interventions.
The less animal products someone consumes, the lower his body mass index on average and the less he tends to be extroverted. A connection with depressive moods as other studies had found could not be confirmed.
Researchers have used artificial intelligence to reduce the 'communication gap' for nonverbal people with motor disabilities who rely on computers to converse with others.
Researchers have uncovered a previously unknown substructure in bone tissue using a new X-ray technique to produce 3D images of the internal structure of bones. The discovery potentially questions fundamentally a number of the models of bone tissue and the mechanical properties of bones that, among other things, is used to describe the process of bone formation.
A new study reveals that replacing half of the blood plasma with a mixture of saline and albumin reverses signs of aging and rejuvenates muscle, brain and liver tissue in old mice. The research team is currently finalizing clinical trials to determine if a modified plasma exchange in humans could be used to treat age-associated diseases and improve the overall health of older people.

When Jocelyn Bell first observed the emissions of a pulsar in 1967, the rhythmic pulses of radio waves so confounded astronomers that they considered whether the light could be signals sent by an alien civilization.
Enhance! Researchers at Duke University have developed an algorithm that can upsample a detailed computer-generated portrait of a human face from a heavily pixelated version. It’s strikingly similar to the much-memed “Enhance!” tool from TV crime dramas like “CSI,” which can seemingly pull information out of thin air. The researchers’ AI, dubbed PULSE (Self-Supervised Photo Upsampling via Latent
No one likes to admit they were wrong, but we still have social norms that suggest we all do it from time to time. A well done apology can show respect, build trust, save relationships, and maintain your self-esteem. Saying "I'm sorry you feel that way" does not count. Let's be real, apologizing can be difficult. Nobody likes to admit that they were in the wrong, mistaken, or that they offended s
Tower block games such as Jenga can be used to explain to schoolchildren how lithium-ion batteries work, meeting an educational need to better understand a power source that has become vital to everyday life.
It took only a couple of weeks after the first coronavirus lockdowns in the United States for news reports to bear out what people in the hardest-hit cities immediately saw with their own eyes: When the going got tough, many residents—and especially the wealthy— got out . The outflux was most pronounced in New York City, where an estimated 5 percent of the population vacated the premises for some
High percentages of Vermonters agree with the social distancing measures put in place by the state in response to the coronavirus pandemic and have complied with them, according to a new survey. But their attitudes and actions, while protecting their health, have come at a significant economic cost, especially for low income Vermonters, one of several ways in which poorer Vermonters have been disp

Everyone’s feeling a little frayed these days, but even by those standards, President Donald Trump seemed a little off on Saturday, as he delivered the commencement speech at West Point. The speech was supposed to be a triumphant moment for Trump—he’d insisted on calling cadets back to the United States Military Academy, after they were sent home amid the coronavirus pandemic—but instead it raise
How's the weather on Mars? Tough on rovers, but very good for generating and moving highly reactive chlorine compounds. New research from Washington University in St. Louis planetary scientists shows that Martian dust storms, like the one that eventually shut down the Opportunity rover, drive the cycle of chlorine from surface to atmosphere and may shed light on the potential for finding life on M
In 1972, physicists J. Michael Kosterlitz and David Thouless published a groundbreaking theory of how phase changes could occur in two-dimensional materials. Experiments soon showed that the theory correctly captured the process of a helium film transitioning from a superfluid to a normal fluid, helping to usher in a new era of research on ultra-thin materials, not to mention earning Kosterlitz, a
A cell's membrane acts as a natural shield, a fence around the cell that protects and contains it. It mediates processes that let nutrients through and let waste out, and it acts as a physical barrier to the entry of toxic substances and pathogens, like the viruses SARS-CoV-1 and SARS-CoV-2, the one that causes COVID-19.
Black and female assistant principals are systematically delayed and denied promotion to principal, compared to their White or male counterparts, despite having equivalent qualifications and more experience on average, according to a new study. The findings were published in June in AERA Open, a peer-reviewed, open access journal of the American Educational Research Association.
New research finds that corporate tax-planning practices improve when a company's board takes an interest in tax-planning practices—and better planning results in both less tax uncertainty and a lower tax burden.
How the police use extra powers they have received during Covid-19 will have a long-lasting effect on their relationship with the public, argues a university researcher who is also a senior police officer.
Scientists in Japan and the Netherlands have independently developed anaerobic soil disinfestation, also known as biological soil disinfestation or reductive soil disinfestation, to kill off pathogenic bacteria, parasitic nematodes and even weeds in soils without using pesticides.

The introduction of topology, a branch of mathematics focusing on the properties of 'knots,' into physics has inspired revolutionary concepts such as topological phases of matter and topological phase transitions, which resulted in the Nobel Prize in Physics in 2016.
Batteries belongs to everyday life. A classical battery, the Volta's pile, converts chemical energy into a voltage, which can power electronic circuits. In many quantum technologies, circuits or devices are based on superconducting materials. In such materials, currents may flow without the need of an applied voltage; therefore, there is no need for a classical battery in such a system. These curr
A new study explains for the very first time the principles behind the design of stings, needles, and spikes in animals and plants. The principles can be directly used in the development of new tools and medical equipment.
The management and prognosis of pulmonary hypertension heavily relies on whether the pathology is localized in pulmonary arteries or veins. In particular, at early stages, it is challenging to distinguish pulmonary arterial hypertension (PAH) from the rare subtype of pulmonary veno-occlusive disease (PVOD) because clinical presentations of PAH and PVOD can be similar. A new study in The American J

Treatment leads to fewer vertebral fractures and to fewer other typical fractures in postmenopausal women with severe osteoporosis at high risk of fracture.
The brain and its surrounding blood vessels exist in a close relationship. Researchers from the MPI of Immunobiology and Epigenetics have discovered how cells of the blood vessels sense the metabolic condition of the brain and alter vascular function in response. The result could be important for patients with neurodegenerative disorders such as Alzheimer's because the onset of these age-related d
With all of my posts here about vaccines and antibodies, it’s only fair that I spend some time talking about the potential toxicology problems with both of those. I remain optimistic about both categories, but it’s for sure that not all the candidates being advanced are going to make it through. So what sorts of things go wrong? Well, efficacy, for one: some of them just don’t work so well agains
blue glowing futuristic city (Credit: Viaframe/Getty Images) The COVID-19 pandemic has given us all the first clear picture of what working from home is really like.

Now, Computer scientists have made an important breakthrough in the field of programming languages: their quantum language is the first of its kind that is as elegant, simple and safe as classical computer languages.
Researchers have created a device that can integrate and interact with neuron-like cells. This could be an early step toward an artificial synapse for use in brain-computer interfaces.
In the fight against cancer or chronic infections, the immune system must be active over long periods of time. However, in the long run, the immune defense system often becomes exhausted. Scientists have now found initial evidence in mice that skeletal muscles help to keep the immune system functional in chronic diseases.
A national study measuring parental attitudes toward vaccinations found 6.1% were hesitant about routine childhood immunizations while nearly 26% were hesitant about the influenza vaccine.
The news: Norway is halting its coronavirus contact tracing app, Smittestopp, after criticism from the Norwegian Data Protection Authority, which said that the country’s low rate of infections meant that the app’s privacy invasions were no longer justified. As a result, the app will cease collecting new data, all data collected so far is being deleted, and work on it is effectively paused indefin
Volcanic gases and the planet’s mantle may have held back oxygen’s rise on Earth, researchers say. Oxygen first accumulated in the Earth’s atmosphere about 2.4 billion years ago, during the Great Oxidation Event. A long-standing puzzle has been that geologic clues suggest early bacteria were photosynthesizing and pumping out oxygen hundreds of millions of years before then. Where was it all going
The more neurotic and anxious cat owners are, the more trust and affection they have for their cat, researchers say. The COVID-19 pandemic may have many people feeling anxious .

CRISPR has sparked a renaissance in genome editing. Now, next-generation CRISPR technologies let scientists modify the genome more efficiently and precisely than before. Such tools could one day serve as therapeutics, but many challenges remain.
The first few days of embryonic development are a critical point for determining the failure or success of a pregnancy. Because relatively few cells make up the embryo during this period, the health of each cell is vital to the health of the overall embryo. But often, these young cells have chromosomal aneuploidies—meaning, there are too many or too few chromosome copies in the cell. Aneuploid cel
Political candidates' use of humor on social media could sometimes backfire on them with potential supporters, new research suggests. People were more likely to view messages using humor as inappropriate for a political candidate they didn't know, the study found. That led participants to rate a candidate using humor as less credible than one who didn't — and less likely to get their vote.
