In a highly unusual decision, the C.D.C. director, Rochelle Walensky, reversed a move by agency advisers and endorsed additional doses of the Pfizer-BioNTech vaccine for health care workers, teachers and other workers at risk.
At Breitbart News , the politics of vaccination have taken a strange turn. A longtime writer at the populist-right website who wants to save his Donald Trump–supporting readers from COVID-19 is speculating that the left has tricked them into rejecting safe and effective vaccines. John Nolte is vaccinated himself and, in an article this week, correctly notes that the shots are “a lifesaver.” But e
Ancient tracks found in New Mexico are believed to be between 21,000 and 23,000 years old, study says New scientific research conducted by archaeologists has uncovered what they believe are the oldest known human footprints in North America.

The study was published in Communication
Throughout the last administration, Department of Homeland Security officials at all levels—from Senate-confirmed power brokers in Washington to rank-and-file agents along the border—often complained that they were facing a double standard: They were doing the same work, using the same methods, as they had under previous presidents, they said, but because their boss was now Donald Trump, the publ
An international team of researchers led by the University of Huddersfield's Archaeogenetics Research Group, including geneticists, archeological scientists, and archeologists, has published the genome sequence of a unique individual from Islamic medieval Spain—al-Andalus—the results of which have shed light on a brutal event that took place in medieval Spain.
On 16 December 2020 the Chang'e-5 mission, China's first sample return mission to the Moon, successfully delivered to Earth nearly two kilograms of rocky fragments and dust from our celestial companion. Chang'e-5 landed on an area of the Moon not sampled by the NASA Apollo or the Soviet Luna missions nearly 50 years ago, and retrieved fragments of the youngest lunar rocks ever brought back for ana
Brighter clouds reduce the amount of solar radiation reaching the Earth's surface, thereby cooling the surface. Emissions of organic compounds from vegetation increase with increasing temperature, thus having the capability to slow down climate warming.
Both of the mRNA vaccines available in the US are highly effective against severe COVID-19, but recent studies suggest that Moderna’s elicits a stronger immune response and might be better at preventing breakthrough infections.
Researchers excavated human footprints out of a small bluff next to a dried-up playa lake and radiocarbon-dated embedded seeds to around 23,000 years ago. Their results suggest that people entered the Americas thousands of years earlier than the accepted estimate.
A team of scientists dated the footprints along an extinct lake bed in New Mexico and found them to be between 21,000 and 23,000 years old — far older than reliable evidence has suggested to date. (Image credit: National Park Service via AP)
Giant Bucket Over the past few years, many professors have noticed an alarming trend among their students. Overall, members of Gen Z, even those studying technical scientific fields , seem to have a total misunderstanding of computer storage, The Verge reports , and many fail to conceptualize the concept of directories and folders filled with digital files. “The most intuitive thing would be the
Crypto Crackdown China has declared all cryptocurrency transactions and any related activities within its borders illegal — a massive crackdown that has sent Bitcoin plummeting yet again. The cryptocurrency fell from highs of just over $45,000 early Friday morning down to under $41,000 around 7 am Eastern. The People’s Bank of China made the announcement in a Q&A posted to its website . “Overseas
Weather Channel Thanks to a combination of observations from both terrestrial and orbital telescopes, a team of scientists got their closest look yet at the distant exoplanet WASP-127b.

Big Breakup According to an exclusive by celebrity gossip magazine Page Six , SpaceX CEO Elon Musk and acclaimed musician Claire “Grimes” Boucher, who had been dating for three years, have broken up. “We are semi-separated but still love each other, see each other frequently and are on great terms,” Musk told the publication. “It’s mostly that my work at SpaceX and Tesla requires me to be primari
D onald Trump’s rise to power generated a flood of media coverage and academic research on authoritarianism—or at least the kind of authoritarianism that exists on the political right. Over the past several years, some researchers have theorized that Trump couldn’t have won in 2016 without support from Americans who deplore political compromise and want leaders to rule with a strong hand. Althoug
As the pandemic drags on into a bleak and indeterminate future, so does the question of its origins. The consensus view from 2020, that SARS-CoV-2 emerged naturally , through a jump from bats to humans (maybe with another animal between), persists unchanged. But suspicions that the outbreak started from a laboratory accident remain, shall we say, endemic. For months now, a steady drip of revelati
A memorable scene in the new film The Eyes of Tammy Faye encapsulates the biopic’s modern perspective on its much-maligned subject. A dashing and boyish TV preacher named Pat Robertson (played by Gabriel Olds) has thrown a swanky poolside soiree at his palatial Virginia mansion. The era is the early 1970s, and fundamentalist Christians are alarmed that progressive cultural movements—for civil rig
The definition of full vaccination against COVID-19 has, since the winter, been somewhat difficult to nail down. It takes one dose of Johnson & Johnson, but two doses of an mRNA vaccine. The CDC counts you as fully vaccinated as soon as you get your last shot, but tells you that you won’t be fully vaccinated until two weeks after that. People have a hard time knowing exactly when it might be safe
The announcement that the Pfizer vaccine appears to work in children ages 5 to 11 is welcome news for many families across the United States. Parents who expect their children’s classrooms to soon be full of vaccinated students shouldn’t be overly optimistic, though. Many moms and dads will wait to get their kids immunized, if they do at all—and that includes those who are vaccinated themselves.

Clouds are one of the biggest wildcards in predictions of how much and how fast the Arctic will continue to warm in the future. Depending on the time of the year and the changing environment in which they form and exist, clouds can both act to warm and cool the surface below them.
If 2020 was a year of death, COVID-19 was not the only culprit. Last year saw the largest increase in murders on record, according to new federal-government data. There were some 21,500 murders in 2020—nearly 5,000 more than in 2019. That’s a 29 percent spike, far outpacing the previous record increase, 12.7 percent, set in 1968. Those numbers come from the FBI’s Uniform Crime Report, an annual r
New private text messages have surfaced between Theranos founder Elizabeth Holmes and her then-boyfriend Sunny Balwani. The nearly 600 pages of private text and Skype messages, sent between June 2011 and July 2016, were obtained by CNBC earlier this week. The texts demonstrate how Holmes professed full confidence in her blood-testing company — despite the venture imploding spectacularly in 2015.
This year is the 20th anniversary of sequencing the human genome. In honor of this event, a research team led by Prof. FU Qiaomei from the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences reviewed the most recent progress in the field of ancient DNA (aDNA), i.e., DNA obtained from the remains of past organisms.
At least one out of four white dwarfs (WDs) will end its life as a magnetic star, and therefore magnetic fields are an essential component of WD physics. New insights into the magnetism of degenerate stars from a recent analysis of a volume-limited sample of WDs have provided the best evidence obtained so far of how the frequency of magnetism in WDs correlates with age. This could help to explain

The service provided by pollinators is particularly important for securing food produced by the more than two billio
While surveys have shown a large share of unvaccinated workers threatening to quit over a mandate, the reality is that companies with mandates have generally seen less than 1% leave rather than get a shot.
A new study found that adults who reported experiencing sexual abuse by the age of 16 had a 2.6 times higher risk of dying in middle age — that is, between 45 and 58 — than those who did not report sexual abuse.
Researchers used ancient DNA analysis to identify a member of a population expelled from medieval Spain known as the 'Segorbe Giant'. The results have shed light on the brutal political decision that led to a dramatic change in population following the Christian reconquest of Spain.
This sparkling starfield, captured by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 and Advanced Camera for Surveys, contains the globular cluster ESO 520-21 (also known as Palomar 6). A densely packed, roughly spherical collection of stars, it lies close to the center of the Milky Way, where interstellar gas and dust absorb starlight and make observations more challenging.
It’s crunch time on climate change. The IPCC’s latest report told the world just how bad it is, and…it’s bad. Companies, NGOs, and governments are scrambling for fixes, both short-term and long-term, from banning sale of combustion-engine vehicles to pouring money into hydrogen to building direct air capture plants. And one initiative, launched last week, is taking an “if you can name it, you can
While the range of colors your eyes may perceive extends beyond the words language provides, languages around the globe are remarkably similar in how they partition the space of colors into a vocabulary.

New research from the College of Engineering lays out in detail why ranked-choice voting, combined with multi-member legislative districts, promotes fair representation, particularly when it comes to blunting gerrymandering—the party in power's ability to map a district to its political advantage.
Human cells are usually diploid—they contain two sets of chromosome. Cells in which one chromosome is missing from the duplicated chromosome set are generally not viable. For a long time, the mechanisms responsible for the loss of viability were unknown. This is where researchers at the Technical University of Kaiserslautern (TUK) came in. In collaboration with the European Molecular Biology Labor
Researchers can predict what syllables a bird will sing — and when it will sing them — by reading electrical signals in its brain, reports a new study. The work is an early step toward building vocal prostheses for humans who have lost the ability to speak.
The private space flight, SpaceX, completed a historic mission with the first all-civilian flight crew last weekend.

Nervous system malignancies are characterized by rapid progression and poor survival rates. These clinical observations underscore the need for novel therapeutic insights and pharmacological targets. To this end, here, we identify the orphan nuclear receptor NR5A2/LRH1 as a negative regulator of cancer cell proliferation and promising pharmacological target for nervous…
Extensive classical and quantum mechanical/molecular mechanical (QM/MM) molecular dynamics simulations are used to establish the structural features of the O state in bacteriorhodopsin (bR) and its conversion back to the bR ground state. The computed free energy surface is consistent with available experimental data for the kinetics and thermodynamics of…
We examine how bottom-up (or stimulus-driven) and top-down (or goal-driven) processes govern the distribution of attention in risky choice. In three experiments, participants chose between a certain payoff and the chance of receiving a payoff drawn randomly from an array of eight numbers. We tested the hypothesis that initial attention…
Plant innate immunity is activated upon perception of invasion pattern molecules by plant cell-surface immune receptors. Several bacteria of the genera Pseudomonas and Burkholderia produce rhamnolipids (RLs) from l-rhamnose and (R)-3-hydroxyalkanoate precursors (HAAs). RL and HAA secretion is required to modulate bacterial surface motility, biofilm development, and thus successful colonization…
Endoplasmic reticulum (ER) stress and Unfolded Protein Response (UPR) signaling promote the pathology of many human diseases. Loss-of-function variants of the UPR regulator Activating Transcription Factor 6 (ATF6) cause severe congenital vision loss diseases such as achromatopsia by unclear pathomechanisms. To investigate this, we generated retinal organoids from achromatopsia patient…
The COVID-19 pandemic highlights the importance of efficient and safe vaccine development. Vaccine adjuvants are essential to boost and tailor the immune response to the corresponding pathogen. To allow for an educated selection, we assessed the effect of different adjuvants on human monocyte-derived dendritic cells (DCs) and their ability to…
The COVID-19 pandemic has led to numerous mathematical models for the spread of infection, the majority of which are large compartmental models that implicitly constrain the generation-time distribution. On the other hand, the continuous-time Kermack–McKendrick epidemic model of 1927 (KM27) allows an arbitrary generation-time distribution, but it suffers from the…
Bacterial suspensions show turbulence-like spatiotemporal dynamics and vortices moving irregularly inside the suspensions. Understanding these ordered vortices is an ongoing challenge in active matter physics, and their application to the control of autonomous material transport will provide significant development in microfluidics. Despite the extensive studies, one of the key aspects…
More than two decades ago, my coauthors, Raymond Bradley and Malcolm Hughes, and I published the now iconic “hockey stick” curve. It was a simple graph, derived from large-scale networks of diverse climate proxy (“multiproxy”) data such as tree rings, ice cores, corals, and lake sediments, that captured the unprecedented…
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of the current COVID-19 pandemic, is one of the biggest threats to public health. However, the dynamic of SARS-CoV-2 infection remains poorly understood. Replication-competent recombinant viruses expressing reporter genes provide valuable tools to investigate viral infection. Low levels of reporter…
New research digs into the interplay between the way parents feed their children and emotional eating by parents and children, as well as the influence the parent’s gender has on that association. Most people are familiar with using food as a way to get through a trying time. Known as emotional eating, for some it can be a perfectly appropriate strategy for managing hard feelings, but for others
(Photo: ALMA (ESO/NAOJ/NRAO)/S. Dagnello (NRAO), STScI, K. Whitaker et al.) In a joint effort with ALMA, the Hubble telescope has discovered six huge, rare, ancient galaxies that date from the universe’s most prolific period of star formation. But they’re running on empty. These galaxies have run out of the raw material required to form stars, and we don’t know why. The galaxies were found as par
A volcano in Spain's Canary Islands kept nerves on edge Friday for a fifth day since it erupted, producing loud explosions, a huge ash cloud and cracking open a new fissure that spewed out more fiery molten rock.
Three-quarters of parents whose children are hospitalized want to talk to a hospital staff member about the projected cost of their child’s medical care, but less than 10% of families have such conversations, a new study shows. The finding boosts the argument that patients and their families need better access to financial counselors at hospitals, researchers say. The study, which appears in JAMA
Today, a CDC advisory committee weighed in on who should get Pfizer booster shots and made a pretty nuanced recommendation: Americans 65 and older, yes; people who live in nursing homes, yes; people 50 to 64 with an underlying medical condition, yes; people 18 to 49 with an underlying medical condition, it depends. The panel declined to recommend extra shots for health-care workers or people in o
Heart attack survivors who used a smartphone app to navigate their recovery process for things like medication management and lifestyle changes, were less likely to be readmitted to the hospital within 30 days of discharge. According to the study of 200 survivors, patients who used the app experienced hospital readmission at half the rate of a comparable group given standard aftercare without the
In everyday life, we know lasers from numerous applications such as the laser printer or the supermarket scanner. Industrially, lasers are used in material processing for cutting, drilling and labeling, and in medicine for diagnostic and therapeutic procedures. Laser spectroscopy methods are also indispensable in scientific research.
Working out with more intensity than, say, walking 10,000 steps over the course of a day—drastically improves a person’s fitness, compared to milder forms of exercise, researchers report. Exercise is healthy. That is common knowledge. But just how rigorous should that exercise be in order to really impact a person’s fitness level? And, if you sit all day at a desk, but still manage to get out and

What if diseases could be treated with a patient's own cells, precisely and on demand? Biotech entrepreneur Nabiha Saklayen explains how we could harness advances in biology, machine learning and lasers to create personalized stem cell banks — and develop medicine uniquely designed for each of our bodies.
In traditional crime stories, sharp detectives (usually police officers and almost always white men) piece together trails of evidence to avenge grisly killings (typically of young white women) and achieve justice. They offer neat visions of how crimes are carried out and solved, casting people as either heroes, villains, or victims. They’re also deeply misleading . In recent years, many writers
By Caitlin Looby, Climate Central and Amber Alexander, NBC WHO 13 Des Moines IOWA — Jean Eells dug into the earth on her farm after the fall harvest and discovered a problem. It was 2016 and the farmer that rented her land had just left. When she pulled her spade from the ground she noticed the soil was hard and compact, with layers looking like “thinly stacked dinner plates.” This story was prod
Calabria is a region in southern Italy, famous for its irregular shape that stretches from north to south for around 250 km—separating the Tyrrhenian Sea to the west and the Ionian Sea to the east. The region covers an area of around 15,000 sq km (with over 740 km of coastline) of which agricultural land covers 49%.
It’s been a fun summer for NASA’s InSight lander. Earlier in the season, the lander used scoops of Martian soil to “wash” dust off its solar panels, giving it a much-needed boost in operating power. And it came not a moment too soon. September 18th was a milestone — InSight’s 1000th sol on Mars — and it celebrated by measuring one of the most powerful and longest-lasting Marsquakes the lander has
Different forms of linear transformations, such as the Fourier transform, are widely employed in processing of information in various applications. These transformations are generally implemented in the digital domain using electronic processors, and their computation speed is limited with the capacity of the electronic chip being used, which sets a bottleneck as the data and image size get large.
The tell-tale signs that autumn is here are clear to us; the days are getting shorter and the temperature is decreasing. We take this as a sign to pull out our winter woolies and think about turning on the radiators. But how do insects know that winter is coming? And what do they do to prepare?

Pacific oyster faming is a multi-billion dollar industry, but there are strong concerns about the ability of oyster larvae to develop properly and survive in future ocean acidification scenarios. A recent study from University of Gothenburg shows that long-term breeding might reduce the genetic response to experimental ocean acidification in oyster larvae. The capacity to adapt to future environme
Fifty years ago, the strategy-based game Oregon Trail hit classrooms around the country. Anyone who has played the game knows that crossing a river in the wrong place at the wrong time or other poor decisions along the trail can end the game.
In 2020, between 720 and 811 million people suffered from hunger, and almost as many (768 million) were malnourished. Two billion people did not get enough essential nutrients and vitamins due to unbalanced diets or a lack of fresh food. At the same time, the number of overweight (1.9 billion) and obese (650 million) people is increasing worldwide. This gross contradiction makes it all the more ur
National Curriculum Key Stage 2 tests taken by 10- and 11-year-old children in England to assess progress in English and Mathematics do not seem to affect children's wellbeing, according to new UCL-led research.
A well-known method for making polymer materials is to blend or mix multiple polymers. For disperse blends, two liquid polymers do not mix well with each other, leading to a so-called droplet-in-matrix microstructure which is similar to emulsions of oil and water. The material properties of the polymer blend depend on the final microstructure, so the material properties can be tuned during process
This week 20 women are tucking themselves in a waterbed for five days as part of a dry immersion study to recreate some of the effects of spaceflight on the body. The campaign kicked off yesterday with the first two subjects at the Medes space clinic in Toulouse, France.
Increasingly extreme heat threatens the health and comfort of city dwellers. That's why researchers from the University of Georgia have developed a new dynamic heat exposure index that captures varying heat exposure within urban environments.
Britain's birth rates are plunging. The number of babies being born has been in steep decline since 2017. Now, researchers are investigating early signs that the pandemic may have caused rates to drop even further.
EPFL scientists have studied two mechanisms that can help bring oxygen to the depths of a lake—essential for preserving the lake's ecosystem. The classical deepwater renewal caused by surface cooling during winter is becoming less efficient due to climate change, especially in deep lakes.
With its steep topography and abundant water resources the Himalayas offer sustainable, low-carbon hydropower for energy-hungry South Asia. But there is a catch—the mountain range falls in one of the world's most seismically active regions.
If we want to transition to a greener, healthier and more climate resilient Europe, it is important to ensure our soils are in good condition. However, the quality of soils is worsening because of unsustainable management practices, depletion of resources, climate change and pollution.
I am interested in biologically plausible models of Reinforcement Learning, but so far feel they fall short in one or more key criteria. Models that claim plausibility tend to make this link based on some evidence, normally neuroscience based. Many differing models may be proposed, but they are unlikely to ALL be correct. Because neurons are noisy and difficult to measure (particularly in real li
Kids anxious about heading back to school after a year of pandemic lockdown can best be helped by parents and teachers getting themselves grounded and present, says a University of Alberta education expert.
Dioxins are a group of toxic and persistent environmental pollutants. These compounds are formed through a variety of processes but commonly through incomplete combustion of organic matter. Levels are usually monitored in industrial settings for safety reasons using offline laboratory analyses that are carried out periodically.

An international team of scientists have created a three-dimensional (3D) pancreatic cancer tumour model in the laboratory, combining a bioengineered matrix and patient-derived cells that could be used to develop and test targeted treatments.
Researchers have developed a new way of determining the age of a lobster based on its DNA. Lobsters are notoriously difficult to age. Nobody knows exactly how old they can get, and some experts have estimated they could live on the ocean floor for as long as a century or more. Until now, a lobster's age has usually been estimated using its size – but this is inaccurate as individual lobsters grow
Researchers used machine learning to discover that sperm with a wide head relative to length are more likely to clump together and swim collectively, a rare behavior that sometimes helps them reach an egg faster. The study provides a new method for understanding how form and function are related in cells with complex behaviors in all animals, including humans.
Plants adapt to their nutritional needs by modifying the permeability of their roots through the production or degradation of a cork-like layer called suberin. By studying the regulation of this protective layer in Arabidopsis thaliana, an international team has discovered four molecular factors responsible for the genetic activation of suberin. The identification of these factors allowed the prod

Det vakte politisk forargelse, da Dagens Medicin for et år siden skrev, at Styrelsen for Patientsikkerhed er 22 måneder om at tage ikke-EU lægers ansøgning om dansk autorisation under behandling. Èt år efter er ventetiden blot steget yderligere. Hverken styrelsen eller Sundhedsministeriet har ønsket at stille op til interview.
Udsigten til at få dansk autorisation som ikke-EU læge er så lang og rigid, at Rigshospitalets thoraxanæstesiologiske klinik har måttet opgive at rekruttere læger fra førende lande som USA, Australien og Canada. »Det virker håbløst, at vi som land stadig ikke kan få det her til at lykkes,« lyder det fra specialeansvarlig overlæge.
