Why Aaron Rodgers Felt Free to Mislead People
The Minnesota Vikings quarterback Kirk Cousins and the Brooklyn Nets point guard Kyrie Irving disheartened fans and disappointed their teams by remaining unvaccinated against COVID-19, but at least both athletes kept it real. Neither attempted to deceive the public about his status. Aaron Rodgers, however, made a conscious decision not to tell the truth. Rodgers, the Green Bay Packers' star quart


California Factory Producing 50,000 Lbs of Lab Grown Meat Per Year
Lab Rats A new facility in the Bay Area is producing lab grown meat on a massive scale, capable of producing an astonishing 400,000 pounds a year, the San Francisco Chronicle reports — though for now, production is capped at a still-impressive 50,000 pounds per year. The factory covers 53,000 square feet and is run by food tech company Upside Foods, a Berkeley spin-off. The lab grown meat industr
Person Furious That Someone Right Click Saved Their Precious NFT
In a mystifying new trend, people are willing to spend an astonishing amount of money on digital pieces of artwork in order to own exclusive rights to them. Non-fungibles tokens, or NFTs, have become a mainstay of the cryptocurrency world, offering those who have plenty of cash or crypto to spare a way to "reinvest" it in what they say is exclusive ownership over what often amounts to not much mo
COVID-Vaccine Mandates for Kids Are Coming
COVID-19 vaccination for 5-to-11-year-olds is finally a go . But even as the emergency-use-authorization process unfolded, so too did arguments over whether kids should (or would soon) be forced into getting shots. School mandates for new vaccines tend to lag behind CDC recommendations by about half a decade, but COVID-19 shots appear to be in the express lane. The Los Angeles Unified School Dist
Pfizer Covid pill 'can cut hospitalisations and deaths by nearly 90%'
Experimental antiviral pill taken at home is highly effective at preventing deaths, trial suggests Coronavirus – latest updates See all our coronavirus coverage A large study of Pfizer's experimental antiviral pill, paxlovid, has found that the drug can cut hospitalisations and deaths from Covid by nearly 90%, the company has said.

What is chemistry?
Chemistry is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy.
The vast little library inside your cells
The human genome can be thought of as a massive library, containing over 20,000 different "instruction manuals": your genes. For example, there are genes which contain information to build a brain cell, a skin cell, a white blood cell, and so on. There are even genes that contain information about regulating the genome itself—like books that explain how to organize a library. The ability to regula
Secondary forests restore fresh water sources in degraded landscapes
New research, published in Scientific Reports by Smithsonian Tropical Research Institute (STRI) postdoctoral fellow Karina Chavarria and colleagues, shows that bacterial communities in streams adjacent to young secondary forests recover to resemble those of mature forest streams in as little as a decade after cattle has been removed from the land, and that these communities are robust throughout t
Go with the flow: how period clothing went mainstream
Period underwear is branching out into leak-proof exercise clothes, swimsuits, sleepwear – even blankets. Is this finally the end of tampons and pads? I suppose everyone who has ever got their period has the same nightmare, though for most of us, it's come true. Mine happened a couple of years ago while reporting at a festival on New York's Governors Island. It was August, hot and sticky, and I w
Dual-drug treatment offers hope to children with rare brain cancer
Scientists make 'promising' breakthrough on fast-growing DIPG type of tumour Scientists have successfully combined two existing cancer drugs to create a treatment for children diagnosed with deadly brain tumours. Diffuse intrinsic pontine glioma (DIPG), a rare and fast-growing type of brain tumour in children, can mutate and evolve to resist treatment with a single drug. There is currently no cur
Eruption From the Sun May Affect Power Grid, Scientists Say
Big Storm A massive solar storm is bombarding the Earth with so much radiation that it could interfere with power grids. The Space Weather Prediction Center (SWPC), which is run by the National Oceanic and Atmospheric Administration (NOAA), has warned in a Thursday statement that the storm could cause possible "power system voltage irregularities." Spacecraft could also "experience surface chargi
Climate Conference Menu Mocked for Absurdly High Carbon Footprint
Carbon on the Menu The Glasgow Climate Change Conference has been rife with double standards, with many world leaders making the trip to Scotland on board their private jets . Even the food being served at this year's COP26, an event put on by the United Nations, had its own substantial carbon footprint. The catering provided at the event made use of plenty of meat and fish, which is ironic given
Mystery Object Detected Near Chinese Satellite
Last month, China launched a satellite called Shijian-21, designed to test new ways to clean up space debris . And this week, the US Space Force detected and catalogued a new object, suspected to be a rocket body designed to take satellites into a geostationary orbit called an apogee kick motor (AKM), SpaceNews reports . But oddly enough, the object is still in geostationary orbit next to Shijian
Study into gene that affects Covid severity should be treated with caution
Immune defences in lungs can vary with ethnicity – but doubts remain over data quality and socio-economic factors Coronavirus – latest updates See all our coronavirus coverage The statistics are stark.

How About Never?
A few years ago, on the eve of my giving a commencement address at Emma Willard, a girls' boarding school in upstate New York, the mother of one of the graduates approached me with a question: "If you could go back to your younger self—say, six years after you'd graduated from high school—what would you ask?" I thought about it for a second and then said, "I'm not so sure I'd ask my younger self
Welsh study shows impact of Covid on 10- and 11-year-olds
Children ate less healthily, took less exercise and had more emotional problems, say researchers Children in the UK ate fewer vegetables, took less exercise and experienced worsening emotional difficulties following the Covid outbreak, according to a research study. A biennial survey conducted by investigators at Cardiff University found that primary school-age children reported a sharp increase
Neutrons take a deep dive into water networks surrounding DNA
Water plays several important roles within the human body, even affecting the DNA in our cells. The entire surface of a DNA double helix is coated in layers of water molecules. This sheath of water attaches to the genetic material through hydrogen bonds, made by sharing hydrogen atoms between molecules. Through hydrogen bonds, water can influence how DNA takes shape and interacts with other molecu
The Singularity Is Here
Paul Spella / The Atlantic This essay has been adapted from a lecture delivered at the Newark Public Library in honor of Philip Roth. Something unnatural is afoot. Our affinities are increasingly no longer our own, but rather are selected for us for the purpose of automated economic gain. The automation of our cognition and the predictive power of technology to monetize our behavior, indeed our v
America Needs a New Scientific Revolution
T wo stories in science are worth cheering right now: the amazing amount of knowledge humanity is gathering about COVID-19 and the quietly revolutionary ways we're accelerating the pace of discovery. First, the knowledge: Last week, a large clinical trial concluded that the cheap antidepressant drug fluvoxamine dramatically lowers the chance that people with COVID-19 will get hospitalized or die.

Fractured artificial rock helps crack a 54-year-old mystery
Princeton researchers have solved a 54-year-old puzzle about why certain fluids strangely slow down under pressure when flowing through porous materials, such as soils and sedimentary rocks. The findings could help improve many important processes in energy, environmental and industrial sectors, from oil recovery to groundwater remediation.
You Won't Regret Rewatching The Ring
The 2002 horror film The Ring can be summarized in a delightfully analog fashion: After finding a VHS tape and receiving a phone call, a local newspaper reporter searches library archives to solve a mystery. As John Mulaney would say , that is a very old-fashioned sentence. But while audiences today have little to fear from a ghost that travels by VHS and kills by landline, the terrors in Gore Ve
A fungus that uses chemicals to trick male flies into mating with infected dead females
A combined team of researchers from the University of Copenhagen and the Swedish University of Agricultural Sciences reports that a certain fungus uses chemicals to trick male flies into mating with infected dead females. They have written a paper describing their findings and have posted it on the bioXiv preprint server.
The Next Weird Way We're Changing Cats
The first thing to know is that truly allergen-free cats are a myth. Sorry. That's because all cats—longhair, shorthair, no hair—shed a pernicious little protein called Fel d 1, found in the saliva and oil glands, which causes most cat allergies. Some cats shed 80 times more of it than others of the same breed; no one knows why. Some shed more one month and less the next. Certain breeds may indee
Creating ultra-diffuse galaxies
Ultra-diffuse galaxies (UDGs) have very low luminosities, comparatively few stars, and little star-formation activity as compared with normal galaxies of similar sizes. Commonly found in galaxy clusters, UDGs come in a wide range of sizes and shapes, many of them being round and smooth like dwarf elliptical galaxies, others showing distorted shapes from having experienced tidal disruptions; some h
Scanning a single protein, one amino acid at a time
Using nanopore DNA sequencing technology, researchers from TU Delft and the University of Illinois have managed to scan a single protein. By slowly moving a linearized protein through a tiny nanopore, one amino acid at the time, the researchers were able to read off electric currents that relate to the information content of the protein. The researchers published their proof-of-concept in Science
Healable carbon fiber composite offers path to long-lasting, sustainable materials
Because of their high strength and light weight, carbon-fiber-based composite materials are gradually replacing metals for advancing all kinds of products and applications, from airplanes to wind turbines to golf clubs. But there's a trade-off. Once damaged or compromised, the most commonly-used carbon fiber materials are nearly impossible to repair or recycle.
The Atlantic Daily: Still Stuck in the Pandemic Blues? You're Not Alone.
If you're not feeling 100 percent, you're not alone: In a recent NPR poll , half of households reported that someone in the home was experiencing serious problems with depression, anxiety, stress, or sleep. One biweekly Census Bureau survey estimated that almost one in three Americans was experiencing symptoms of depression or anxiety alone. Even after all this time, after all that supposed adjus
Team demonstrates simultaneous readout of 60 bolometers for far-infrared space telescopes
Light with sub-millimeter and far-infrared wavelengths from deep space can travel long distances, penetrating right through dust clouds, and bring us information about the history of the universe and the origin of galaxies, stars and planets. However, the long journey has weakened these signals, and we require sensitive detectors operating at millikelvin temperatures on a space instrument.
Hubble images colorful planetary nebula ringed by hazy halo
NGC 2438 is a planetary nebula, formed after the death of a Sun-like star. The medium-sized star would have expelled its outer layers of gas into space as it died, leaving behind a white-dwarf core. A halo of glowing gas over 4.5 light-years across surrounds the nebula's brighter inner ring. Many round or nearly round planetary nebulae display these halo structures, and astronomers have been inves
Evolution led to similarities in the melodies of animal vocalizations and human languages
When listening closely, the melodies of human languages and animal vocalizations are very similar. However, it is not yet fully resolved if similar patterns in languages and animal vocalizations also have similar meanings. Researchers of the University of Vienna present a new method to decode the meaning of animal vocalizations: the comparison of their melodies with human languages. The proposal w
Novel tag provides first detailed look into goliath grouper behavior
A new study reveals detailed behavior of massive goliath groupers. Until now, no studies have documented their fine-scale behavior. What is known about them has been learned from divers, underwater video footage, and observing them in captivity. Using a multi-sensor tag with a three axis accelerometer, gyroscope and magnetometer as well as a temperature, pressure and light sensor, a video camera a
When macrophages let off steam
New data shows how inflammatory reactions can be resolved by changes to the metabolism of macrophages. Danger signals released by damaged cells during inflammation play a role during this process. 'Rewiring' the mitochondria in the macrophages protects them against overloading and can thus improve the way in which parts of damaged cells are eliminated and resolve the inflammatory reaction.
Multispecific targeting of glioblastoma with tumor microenvironment-responsive multifunctional engineered NK cells [Medical Sciences]
Tumor antigen heterogeneity, a severely immunosuppressive tumor microenvironment (TME) and lymphopenia resulting in inadequate immune intratumoral trafficking, have rendered glioblastoma (GBM) highly resistant to therapy. To address these obstacles, here we describe a unique, sophisticated combinatorial platform for GBM: a cooperative multifunctional immunotherapy based on genetically engineered h
Electron family creates previously unknown state of matter
An international research team has demonstrated a completely novel state of matter in a metal. It is created by the combination of four electrons-until now, only electron pairs were known. This discovery could lead to a new type of superconductivity, an entirely new research direction, and revolutionary technologies such as quantum sensors.
How cells correctly choose active genes
It is essential for cells to control precisely which of the many genes of their genetic material they use. This is done in so-called transcription factories, molecular clusters in the nucleus. Researchers have now found that the formation of transcription factories resembles the condensation of liquids. Their findings will improve the understanding of causes of diseases and advance the development

Stable cycles are essential for ecosystem persistence because they allow resources and nutrients to be…
A stable proportion of Purkinje cell inputs from parallel fibers are silent during cerebellar maturation [Neuroscience]
Cerebellar Purkinje neurons integrate information transmitted at excitatory synapses formed by granule cells. Although these synapses are considered essential sites for learning, most of them appear not to transmit any detectable electrical information and have been defined as silent. It has been proposed that silent synapses are required to maximize…
Bacterial marginolactones trigger formation of algal gloeocapsoids, protective aggregates on the verge of multicellularity [Microbiology]
Photosynthetic microorganisms including the green alga Chlamydomonas reinhardtii are essential to terrestrial habitats as they start the carbon cycle by conversion of CO2 to energy-rich organic carbohydrates. Terrestrial habitats are densely populated, and hence, microbial interactions mediated by natural products are inevitable. We previously discovered such an interaction between Streptomyces…

However, the most widely used fluorescent probes for myelin…
Monitoring RNA dynamics in native transcriptional complexes [Biochemistry]
Cotranscriptional RNA folding is crucial for the timely control of biological processes, but because of its transient nature, its study has remained challenging. While single-molecule Förster resonance energy transfer (smFRET) is unique to investigate transient RNA structures, its application to cotranscriptional studies has been limited to nonnative systems lacking RNA…
Activation of PTH1R alleviates epididymitis and orchitis through Gq and {beta}-arrestin-1 pathways [Pharmacology]
Inflammation in the epididymis and testis contributes significantly to male infertility. Alternative therapeutic avenues treating epididymitis and orchitis are expected since current therapies using antibiotics have limitations associated to side effects and are commonly ineffective for inflammation due to nonbacterial causes. Here, we demonstrated that type 1 parathyroid hormone receptor…
A reactive center loop-based prediction platform to enhance the design of therapeutic SERPINs [Biochemistry]
Serine proteases are essential for many physiological processes and require tight regulation by serine protease inhibitors (SERPINs). A disturbed SERPIN–protease balance may result in disease. The reactive center loop (RCL) contains an enzymatic cleavage site between the P1 through P1' residues that controls SERPIN specificity. This RCL can be modified…

Ember Mug Review: Make Your Cup of Joe Last Longer
For 62 percent of Americans , a cup of coffee is an essential part of their day, according to the NCA. For some, it's all about the ritual of grinding premium beans from a local roaster, carefully brewing a fresh cup, and sharing it with a family member. For others, coffee is all about getting a much-needed hit of caffeine as soon as possible to jump-start a busy day. Whatever your reason for ind
Democrats Are Getting Crushed in the 'Vibes War'
To explain the Democrats' poor performance in state and local elections Tuesday, various commentators have made very specific claims: It was mostly about critical race theory , or mostly about Terry McAuliffe's flaws as a candidate for Virginia governor , or mostly about suburban white women voting like it's 2012 again. But none of these explanations is fully satisfying. The turn against Democrat
Actually, Kristen Stewart Has Always Been a Great Actor
Kristen Stewart hit the height of her fame as the star of the Twilight movies about a decade ago, and to many audiences she will always be a teenage girl falling in love with a vampire. Last month, in an interview with Britain's Sunday Times , the actor said she's probably made "five really good films" at most. The quip immediately inspired blog posts and social-media jokes about how perhaps the

Comet's intense heat turned sand to glass 12,000 years ago
Around 12,000 years ago, something scorched a vast swath of the Atacama Desert in Chile with heat so intense that it turned the sandy soil into widespread slabs of silicate glass. Now, researchers know what caused the inferno. In a study in Geology , researchers show that samples of the desert glass contain tiny fragments with minerals often found in rocks of extraterrestrial origin. Those minera
Polymer-coated nanoparticles to promote drug delivery to the brain
Treating diseases such as Alzheimer's or Parkinson's is a challenge because drugs have to be able to cross the blood–brain barrier. As a result, the doses administered must be high and only a small fraction reaches the brain, which can lead to significant systemic side effects. To solve this issue, the postdoctoral researcher Jean-Michel Rabanel, under the supervison of Professor Charles Ramassamy
Researchers positive about open science, but there are still obstacles
Eighty-seven percent of all researchers have a (very) positive attitude about open science. Young scientists are even more enthusiastic with a percentage of 94 percent. But researchers are still coming across obstacles when it comes to practical implementation. This has emerged from a poll commissioned by NWO among researchers from all disciplines.
Making entropy production work
While Rolf Landauer was working at IBM in the early 1960s, he had a startling insight about how heat, entropy, and information were connected. Landauer realized that manipulating information releases heat and increases entropy, or the disorder of the environment. He used this to calculate a theoretical lower limit for heat released from a computation, such as erasing a bit. At room temperature, th

African Sahelian farmers diversify crops to adapt to climate change
Farming communities in the African Sahel have adapted their crops to the high seasonal variability and rising temperatures caused by climate change over this past century. This is the main conclusion of a study carried out by the Institute of Environmental Science and Technology of the Universitat Autònoma de Barcelona (ICTA-UAB), which highlights the importance of environmental knowledge of rural
Strengthening the second law of thermodynamics
According to the second law of thermodynamics, the total entropy of a closed process can increase or stay the same, but never decrease. The second law guarantees, for example, that an egg can wobble off a table and leave a mess on the floor but that such a mess will never spontaneously form an egg and leap back on the table. Or that air will escape a balloon but never, on its own accord, inflate i

Environmental policy expert explores the promise of forests to alleviate poverty
More than 100 world leaders have promised to halt and reverse deforestation by 2030, in the first major deal of the 26th United Nations Climate Change Conference (COP26) in Glasgow. Deforestation contributes to global climate change because it means forests can no longer absorb carbon dioxide, a greenhouse gas. Ending deforestation is necessary to meet global climate targets, but what might this d
Experts draw up roadmap to avert cooling-generated climate catastrophe
A team of experts including researchers from the World Bank Group and University of Birmingham has developed a roadmap to drive the cooling innovations that could help to avoid climate catastrophe, as increasing heat threatens human health and productivity and rising global demand for cooling further raise the planet's temperatures.

Questioning the ethics of collecting endangered insects for study
"I have developed a real passion for a midge," said Valeria Lencioni in an interview with GlacierHub. The midge in question, Diamesa steinboecki, is a highly endangered insect that she observed in the glacial streams of the Italian Alps where she conducts her research. When she started studying glacial fauna in 1996, little was known about the insects that populated the icy habitats. Lencioni help
Nanoscale self-assembling salt-crystal 'origami' balls envelop liquids
Researchers have developed a technique whereby they can spontaneously encapsulate microscopic droplets of water and oil emulsion in a tiny sphere made of salt crystals—sort of like a minute, self-constructing origami soccer ball filled with liquid. The process, which they are calling 'crystal capillary origami,' could be used in a range of fields from more precise drug delivery to nanoscale medica
2 things cause weak quads after ACL surgery
The quadriceps weakness common after anterior cruciate ligament, or ACL, reconstruction surgery isn't just the result of muscle atrophy, research indicates. The researchers find that besides muscle loss, the quadricep muscle—specifically, the fibers within that muscle—contract differently. Taken together, these deficits result in a muscle that is weaker and behaves like that of someone much older
Atacama desert plants may hold clues to saving crops
Researchers have identified genes associated with plant survival in one of the harshest environments on Earth: the Atacama Desert in Chile. Their findings, published in Proceedings of the National Academy of Sciences , may help scientists breed resilient crops that can thrive in increasingly drier climates. "In an era of accelerated climate change, it is critical to uncover the genetic basis to i

Nature Communications, Published online: 05 November 2021; doi:10.1038/s41467-021-26818-3 Though metamaterials enhance nonlinear light-matter interactions due to their resonant features, these materials typically show a narrow spectral bandwidth. Here, the authors report broadband enhanced second-harmonic generation in patterned multilayer hyperbolic metamaterial arrays.
Insecticide resistance by a host-symbiont reciprocal detoxification
Nature Communications, Published online: 05 November 2021; doi:10.1038/s41467-021-26649-2 Insect acquisition of insecticide resistance represents a serious problem for agriculture. Here, authors reveal an insect symbiotic bacteria that degrades insecticide fenitrothion into a non-insecticidal but bactericidal compound, which is subsequently excreted by the insect host.
Mitigation potential of global ammonia emissions and related health impacts in the trade network
Nature Communications, Published online: 05 November 2021; doi:10.1038/s41467-021-25854-3 Ammonia emissions from agricultural sources can cause severe health impacts. Here, the authors show that about 25% of global agricultural ammonia emissions in 2012 were related to international exported goods and caused 61 thousand PM2.5 related premature deaths, which points out large ammonia mitigation pot
Pseudoknot length modulates the folding, conformational dynamics, and robustness of Xrn1 resistance of flaviviral xrRNAs
Nature Communications, Published online: 05 November 2021; doi:10.1038/s41467-021-26616-x Exoribonuclease-resistant RNAs (xrRNAs) are RNA elements that block the exoribonucleolytic degradation of RNA. Here the authors show how a long-range pseudoknot length modulates the Mg2+-dependence of flaviviral xrRNA's folding, conformational dynamics and Xrn1 resistance.
Interview: Katharine Hayhoe on How to Talk About Climate Change
A leading expert on global warming discusses how honest, one-on-one conversations can make a difference in motivating meaningful large-scale action. Those conversations aren't always easy, but Katharine Hayhoe maintains that the vast majority are still willing to listen, especially to those they are close to.
A giant NLR gene confers broad-spectrum resistance to Phytophthora sojae in soybean
Nature Communications, Published online: 05 November 2021; doi:10.1038/s41467-021-26554-8 While multiple resistance-to-Phytophthora sojae loci/alleles have been mapped in soybean, many of them have become ineffective to newly evolved isolates. Here, the authors show that a 27.7-kb nucleotide-binding site-leucine-rich repeat gene confers broad-spectrum resistance to P. sojae in soybean.

Children, Underlying Conditions, and COVID-19
That we can identify children who have a higher risk for severe outcomes shouldn't be used to minimize the virus and argue against vaccination in healthy children. Rather, we should recognize there are populations of vulnerable children that need extra protection, and the best way to do this is through vaccinating ourselves and all eligible children. The post first appeared on Science-Based Medi
Do monogenetic volcanoes threaten the southwestern US?
New research clarifies monogenetic volcanoes, a type of volcanic hazard that can pose important dangers despite its short lifespan. These volcanoes erupt for a period that might last for days, years, or decades. Then, they go dark and die. The landscape of the southwestern United States is heavily scarred by past eruptions of such volcanoes, and a new study marks a step toward understanding futur
Nerves may be key to blocking abnormal bone growth in tissue
Blocking a molecule that draws sensory nerves into musculoskeletal injuries prevents heterotopic ossification (HO), a process in which bone abnormally grows in soft tissue during healing, researchers reported. The findings suggest that drugs currently being tested in clinical trials to inhibit this molecule for pain relief could also protect against this challenging condition.
