Hugh Laurie, the actor best known from hit TV drama “House MD,” took to Twitter today to absolutely roast the anti-vaccination movement — or, at least, we’re pretty sure he did. “I find the injunction ‘think for yourself’ very stirring — until I remember that I could never have conceived of 99 percent of the concepts I rely on every day to survive,” a contemplative Laurie wrote . “I’m extremely g
The diversity of human languages can be likened to branches on a tree. If you're reading this in English, you're on a branch that traces back to a common ancestor with Scots, which traces back to a more distant ancestor that split off into German and Dutch. Moving further in, there's the European branch that gave rise to Germanic; Celtic; Albanian; the Slavic languages; the Romance languages like

Two genetics papers that had been published in prominent academic journals have been retracted in response to criticism that their subjects — persecuted Muslim Uyghurs from China — hadn’t fully consented to the process. The studies reveal a bleak trend in which members of Chinese law enforcement or public security officials are listed as coauthors on genetics research papers, suggesting that the
Pilots in control of the suborbital plane that took Virgin Galactic founder Richard Branson high into the upper atmosphere earlier this summer had to make a split second decision. A beeping red light alerted them to a deviation of their planned trajectory, but they forged ahead at three times the sound of speed. As revealed in a New Yorker piece several weeks later, the flight did not go entirely

Cerebral Guy It’s set up to be a historic moment: a crew of four civilians are about to rocket into space on board a SpaceX Crew Dragon capsule. The launch, dubbed Inspiration4, could soon mark the first time an all-non-professional team has ever gone for a trip around the Earth. Interestingly, SpaceX CEO Elon Musk isn’t exactly basking in the limelight ahead of Wednesday’s launch. According to I
Jonathan Neman really seemed to think he was onto something. Last week, in a lengthy, now-deleted post on LinkedIn, the CEO and co-founder of the upscale salad chain Sweetgreen expounded on a topic that might seem a little far afield for a restaurant executive: how to end the pandemic. “No vaccine nor mask will save us,” he wrote. (The vaccines, it should be noted, have so far proved to be near-m
Energy companies and nations must leave nine tenths of Earth’s coal and almost two thirds of its known oil and gas in the ground if the world is to hold temperatures to a target beyond which climate change’s impacts are dangerously amplified, researchers have calculated.
Larry Elder becoming governor of California would be a little like Bernie Sanders winning a Senate seat in Kansas, or Alexandria Ocasio-Cortez representing suburban Mississippi in the House, or Mike Pence ending his career as the mayor of Portland, Oregon.

Alex Majoli / Magnum The United States today does not have so much as an embassy in Afghanistan, Iran, Libya, Syria, or Yemen. It demonstrably has little influence over nominal allies such as Pakistan, which has been aiding the Taliban for decades, and Saudi Arabia, which has prolonged the conflict in Yemen . In Iraq, where almost 5,000 U.S. and allied troops have died since 2003, America must en

Tomorrow marks 20 years since the attacks on September 11, 2001. The adrenaline shock of that morning has long worn off, leaving behind only the horror, the loss, and two decades’ worth of grief. It’s tempting to use this anniversary to consider the attacks as a greater political or cultural moment, to analyze where the country went right or wrong in its response. And doing so is important. But f
Outmoded social taboos notwithstanding, it’s now a matter of common sense that mental health is just as vital and important to a person’s wellbeing as physical health. But even though most of us know this to be true, it’s still not easy to find a good mental health therapist, and the obstacles to finding one remain stubbornly high. And if you have a medical condition or some other reason for not

The 20th anniversary of 9/11 arrives with pessimism and a sense of defeat. 9/11 caused a national trauma that lasted for years. We should remember this when analyzing the mistakes that America made in its war on terrorism during the subsequent 20 years. As the 20th anniversary of the 9/11 terrorist attack approached, I was disappointed to see how negative the media coverage is. The overall report
One of the popular memes in literature, movies and tech journalism is that man's creation will rise and destroy it. Lately, this has taken the form of a fear of AI becoming omnipotent, rising up and annihilating mankind. The economy has jumped on the AI bandwagon; for a certain period, if you did not have "AI" in your investor pitch, you could forget about funding. (Tip: If you are just using a G
The world's most influential conservation congress passed resolutions Friday calling for 80 percent of the Amazon and 30 percent of Earth's surface—land and sea—to be designated "protected areas" to halt and reverse the loss of wildlife.
Several members of a troop of western lowland gorillas at Zoo Atlanta have tested positive for the coronavirus after handlers noticed many of the great apes were showing signs of mild coughing, runny noses and a small loss of appetite, the zoo said Friday.

A new study indicates that an enzyme called protein phosphatase 2 (PP2A) appears to be a major driver of preeclampsia, a dangerous pregnancy complication characterized by the development of high blood pressure and excess protein in the urine. The finding could lead to new treatments for preeclampsia other than premature delivery, which is often the only option.
Researchers examined the differences in prefrontal cortex (PFC) activation between two distinct drawing tasks in virtual reality. Results of the study indicated significant differences between a rote tracing task and a creative self-expression task, with the rote tracing task showing an increase in PFC activity. It also showed there was reduced PFC activation for creative self-expressive tasks, in
Various strategies can help people with Parkinson's who have difficulty walking, but a new study finds that many people have never heard of or tried these strategies. The study also found that how well different compensation strategies worked depended on the context in which they were used, such as indoors versus outdoors, under time pressure or not.
Researchers have shown that people with inflexible metabolisms burn less fat at night than those with flexible metabolism. The team measured the respiratory quotient throughout the night and found that despite equal ages, BMIs, and amount of fat, people with inflexible metabolisms burned more carbohydrates and less fat than did people with flexible metabolisms. The higher sleep-time quotient could

Researchers have determined that enhanced bone resorption activity due to a faulty immune response may underpin multifocal osteomyelitis — painful, chronic bone infections — in children with MSMD, a rare genetic condition resulting from a range of immune system mutations.
Inclusionary zoning policies that increase the supply of affordable housing may be good for the heart, according to new research. The study notes that such zoning programs were associated with lower rates of heart disease.
In a study of the nine largest U.S. cities, researchers found stark racial, ethnic, and socioeconomic inequities in COVID-19 vaccination rates across neighborhoods. The study showed that high vaccination neighborhoods had more white residents, fewer people of color, higher incomes, and lower poverty rates. These high vaccination neighborhoods also had lower historical COVID-19 death rates, showing
Neuroscientists present new findings on how the motor cortex can help learn foreign vocabulary more quickly. The new data suggests that learning techniques that involve the performance of gestures instead of simple audio or visual information can benefit learners.
A new system for sampling fragments of DNA from marine organisms drifting in the ocean is set to create new opportunities for research on biodiversity and ways of supporting conservation activities. The results showed the ferry-collected samples had traces of DNA from all parts of the vertebrate ecosystem, ranging from small prey fish at the base of the food chain, such as anchovies and sardines,
Neuroscientists have developed a computer model to explain how a nematode worm searches for food, revealing that single brain cells can both sense the environment and control a whole animal's foraging strategy. The study involved the microscopic nematode species, Caenorhabditis elegans.
As mice watched movies, neuroscientists watched their brains to see how vision could be represented reliably. The answer is that consistency in representation is governed by a circuit of inhibitory neurons.
Every summer, wildfires rage across the western U.S., and wildland firefighters are tasked with putting them out. But in the process, they inhale smoke and all the compounds in it, which can be harmful at high amounts. Now, researchers have evaluated the presence of particulate matter and volatile organic compounds (VOCs) around firefighters actively combating blazes, finding the highest exposures
Engineers have created a solar-powered electrochemical reaction that not only uses wastewater to make ammonia — the second most-produced chemical in the world — but also achieves a solar-to-fuel efficiency that is 10 times better than any other comparable technology.
Researchers have designed new metasurfaces using nanoscale techniques inspired by kirigami that could offer a new chip-based way to achieve nanoscale control of light, which could lead to better optical displays, information encoding and digital light processing.
Greenland may be best known for its enormous continental scale ice sheet that soars up to 3,000 meters above sea level, whose rapid melting is a leading contributor to global sea level rise. But surrounding this massive ice sheet, which covers 79% of the world's largest island, is Greenland's rugged coastline dotted with ice capped mountainous peaks. These peripheral glaciers and ice caps are now
If the cerebral hemispheres of the forebrain fail to divide properly in an unborn child, this results in holoprosencephaly. A team has discovered candidate genes that can positively influence the severity of this congenital malformation of the forebrain.
The air quality within an office can have significant impacts on employees' cognitive function, including response times and ability to focus, and it may also affect their productivity, according to new research.
Researchers succeed in the direct bonding of diamond and gallium nitride (GaN) at room temperature and demonstrate that the bond can withstand heat treatments of 1,000 degrees Celsius, making it ideal for the high temperature fabrication process of GaN-based devices. GaN-on-diamond semiconductor material will allow for the next generation of high power, high frequency devices.
Good sleep-time recovery is associated with a health-promoting diet and health-promoting eating habits, as well as with lower consumption of alcohol, according to a new study investigating psychological and physiological well-being among working-age Finnish adults.
Pollinators — such as bees, butterflies and birds — are essential for agricultural production. However, natural pollination can also fail or be insufficient, which can lead to lower yields and poorer quality. This means alternative solutions are needed. Hand pollination, in which pollen is applied manually or mechanically to the flower, can supplement or replace pollination by animals. Researche
Researchers have found that coating soybean plant leaves with cellulose nanofiber (CNF) gives protection against an aggressive fungal disease. The CNF coating changed leaf surfaces from water repellent to water absorbent, and suppressed pathogen gene expression associated with infection mechanisms, offering resistance to the destructive Asian rust disease. This is the first study to examine CNF ap
Researchers from Newcastle University, UK have engineered Escherichia coli bacteria to capture carbon dioxide (CO2) using hydrogen gas (H2) to convert it into formic acid.

Many small animals grow their teeth, claws and other “tools" out of materials that are filled with zinc, bromine and manganese, reaching up to 20% of the material's weight. My colleagues and I call these “heavy element biomaterials," and in a new paper , we suggest that these materials make it possible for animals to grow scalpel-sharp and precisely shaped tools that are resistant to breaking, de
After the Biden administration’s announcement on COVID-19 booster shots, questions came up about the ethics of vaccinated people in the US getting a booster when so many people around the world are still waiting for their first dose. And while we’re pondering ethics, is there a selfish argument for the US to lead efforts to vaccinate people around the world? What about vaccine mandates? And when

In high-risk environments with frequent predator encounters, efficient antipredator behavior is key to survival. Parental effects are a powerful mechanism to prepare offspring for coping with such environments, yet clear evidence for adaptive parental effects on offspring antipredator behaviors is missing. Rapid escape reflexes, or “C-start reflexes,” are a key…
Arrestins were initially identified for their role in homologous desensitization and internalization of G protein–coupled receptors. Receptor-bound arrestins also initiate signaling by interacting with other signaling proteins. Arrestins scaffold MAPK signaling cascades, MAPK kinase kinase (MAP3K), MAPK kinase (MAP2K), and MAPK. In particular, arrestins facilitate ERK1/2 activation by scaffolding
Arthritogenic alphaviruses are globally distributed, mosquito-transmitted viruses that cause rheumatological disease in humans and include Chikungunya virus (CHIKV), Mayaro virus (MAYV), and others. Although serological evidence suggests that some antibody-mediated heterologous immunity may be afforded by alphavirus infection, the extent to which broadly neutralizing antibodies that protect agains
Adaptive immune recognition is mediated by the binding of peptide–human leukocyte antigen complexes by T cells. Positive selection of T cells in the thymus is a fundamental step in the generation of a responding T cell repertoire: only those T cells survive that recognize human peptides presented on the surface…
Episodic events are frequently consolidated into labile memory but are not necessarily transferred to persistent long-term memory (LTM). Regulatory mechanisms leading to LTM formation are poorly understood, however, especially at the resolution of identified neurons. Here, we demonstrate enhanced LTM following aversive olfactory conditioning in Drosophila when the transcription factor…
The origins of oscillatory activity in the brain are currently debated, but common to many hypotheses is the notion that they reflect interactions between brain areas. Here, we examine this possibility by manipulating the strength of coupling between two human brain regions, ventral premotor cortex (PMv) and primary motor cortex…
The formation of the branched actin networks is essential for cell polarity, but it remains unclear how the debranching activity of actin filaments contributes to this process. Here, we showed that an evolutionarily conserved coronin family protein, the Caenorhabditis elegans POD-1, debranched the Arp2/3-nucleated actin filaments in vitro. By fluorescence…
Attachment theory is an ethological approach to the development of durable, affective ties between humans. We propose that secure attachment is crucial for understanding climate change mitigation, because the latter is inherently a communal phenomenon resulting from joint action and requiring collective behavioral change. Here, we show that priming attachment…
The phosphoinositide 3-kinase regulatory subunit p85α is a key regulator of kinase signaling and is frequently mutated in cancers. In the present study, we showed that in addition to weakening the inhibitory interaction between p85α and p110α, a group of driver mutations in the p85α N-terminal SH2 domain activated EGFR,…
Long-term synaptic plasticity is believed to be the cellular substrate of learning and memory. Synaptic plasticity rules are defined by the specific complement of receptors at the synapse and the associated downstream signaling mechanisms. In young rodents, at the cerebellar synapse between granule cells (GC) and Purkinje cells (PC), bidirectional…
Membraneless compartments, also known as condensates, provide chemically distinct environments and thus spatially organize the cell. A well-studied example of condensates is P granules in the roundworm Caenorhabditis elegans that play an important role in the development of the germline. P granules are RNA-rich protein condensates that share the key…
All organisms experience fundamental conflicts between divergent metabolic processes. In plants, a pivotal conflict occurs between allocation to growth, which accelerates resource acquisition, and to defense, which protects existing tissue against herbivory. Trade-offs between growth and defense traits are not universally observed, and a central prediction of plant evolutionary ecology…
Interleukin 6 (IL-6) is known to regulate the CD4 T cell function by inducing gene expression of a number of cytokines through activation of Stat3 transcription factor. Here, we reveal that IL-6 strengthens the mechanics of CD4 T cells. The presence of IL-6 during activation of mouse and human CD4…
In multicellular organisms, antiviral defense mechanisms evoke a reliable collective immune response despite the noisy nature of biochemical communication between tissue cells. A molecular hub of this response, the interferon I receptor (IFNAR), discriminates between ligand types by their affinity regardless of concentration. To understand how ligand type can be…
ASCT2 (SLC1A5) is a sodium-dependent neutral amino acid transporter that controls amino acid homeostasis in peripheral tissues. In cancer, ASCT2 is up-regulated where it modulates intracellular glutamine levels, fueling cell proliferation. Nutrient deprivation via ASCT2 inhibition provides a potential strategy for cancer therapy. Here, we rationally designed stereospecific inhibitors exploiting…
The spread of misinformation is a global phenomenon, with implications for elections, state-sanctioned violence, and health outcomes. Yet, even though scholars have investigated the capacity of fact-checking to reduce belief in misinformation, little evidence exists on the global effectiveness of this approach. We describe fact-checking experiments conducted simultaneously in Argentina,…
Late-stage anthrax infections are characterized by dysregulated immune responses and hematogenous spread of Bacillus anthracis, leading to extreme bacteremia, sepsis, multiple organ failure, and, ultimately, death. Despite the bacterium being nonhemolytic, some fulminant anthrax patients develop a secondary atypical hemolytic uremic syndrome (aHUS) through unknown mechanisms. We recapitulated the
Diphthamide, a modification found only on translation elongation factor 2 (EF2), was proposed to suppress −1 frameshifting in translation. Although diphthamide is conserved among all eukaryotes, exactly what proteins are affected by diphthamide deletion is not clear in cells. Through genome-wide profiling for a potential −1 frameshifting site, we identified…
Multiple placental pathologies are associated with failures in trophoblast differentiation, yet the underlying transcriptional regulation is poorly understood. Here, we discovered msh homeobox 2 (MSX2) as a key transcriptional regulator of trophoblast identity using the human trophoblast stem cell model. Depletion of MSX2 resulted in activation of the syncytiotrophoblast transcriptional…
The recent controversy about misinformation has moved a question into the focus of the public eye that has occupied philosophers for decades: Under what conditions is it appropriate to assert a certain claim? When asserting a claim that x, must one know that x? Must x be true? Might it…
Disinhibition is an obligatory initial step in the remodeling of cortical circuits by sensory experience. Our investigation on disinhibitory mechanisms in the classical model of ocular dominance plasticity uncovered an unexpected form of experience-dependent circuit plasticity. In the layer 2/3 of mouse visual cortex, monocular deprivation triggers a complete, “all-or-none,”…
The quest to identify materials with tailored properties is increasingly expanding into high-order composition spaces, with a corresponding combinatorial explosion in the number of candidate materials. A key challenge is to discover regions in composition space where materials have novel properties. Traditional predictive models for material properties are not accurate…
We recently synthesized one-dimensional (1D) van der Waals heterostructures in which different atomic layers (e.g., boron nitride or molybdenum disulfide) seamlessly wrap around a single-walled carbon nanotube (SWCNT) and form a coaxial, crystalized heteronanotube. The growth process of 1D heterostructure is unconventional—different crystals need to nucleate on a highly curved…
β cells produce, store, and secrete insulin upon elevated blood glucose levels. Insulin secretion is a highly regulated process. The probability for insulin secretory granules to undergo fusion with the plasma membrane or being degraded is correlated with their age. However, the molecular features and stimuli connected to this behavior…
Macromolecules such as monoclonal antibodies (mAbs) are likely to experience poor tumor penetration because of their large size, and thus low drug exposure of target cells within a tumor could contribute to suboptimal responses. Given the challenge of inadequate quantitative tools to assess mAb activity within tumors, we hypothesized that…
P2X1 receptors are adenosine triphosphate (ATP)-gated cation channels that are functionally important for male fertility, bladder contraction, and platelet aggregation. The activity of P2X1 receptors is modulated by lipids and intracellular messengers such as cAMP, which can stimulate protein kinase A (PKA). Exchange protein activated by cAMP (EPAC) is another…
Several studies have been devoted to establishing the effects of the COVID-19 pandemic on mental health across gender, age, and ethnicity. However, much less attention has been paid to the differential effect of COVID-19 according to different personalities. We do this using the UK Household Longitudinal Study (UKHLS), a large-scale…
Thermoresponsive microgels are one of the most investigated types of soft colloids, thanks to their ability to undergo a Volume Phase Transition (VPT) close to ambient temperature. However, this fundamental phenomenon still lacks a detailed microscopic understanding, particularly regarding the presence and the role of charges in the deswelling process….
