Sometime this month, Congress is set to release the unclassified version of a long-awaited report into sightings of "unidentified aerial phenomena," the culmination of various reports by military personnel of mysterious UFOs that have at times appeared to defy the laws of physics. Ahead of the release, reporters at The New York Times have gotten an advanced briefing of what we can expect to find
Experts are warning that the sea ice covering much of the Arctic appears to be thinning twice as previously thought, The Guardian reports . In a new study published in the journal The Cryosphere today, a team of researchers have extrapolated how temperature, snowfall and ice floe movement can affect the accumulation of snow. Previously, we've had to rely on data collected by Soviet expeditions on
To test the Standard Model of particle physics, scientists often collide particles using gigantic underground rings. In a similar fashion, high-pressure physicists compress materials to ever greater pressures to further test the quantum theory of condensed matter and challenge predictions made using the most powerful computers.
Less ice means more global heating, a vicious cycle that also leaves the region open to new oil extraction Sea ice across much of the Arctic is thinning twice as fast as previously thought, researchers have found. Arctic ice is melting as the climate crisis drives up temperatures, resulting in a vicious circle in which more dark water is exposed to the sun's heat, leading to even more heating of
Loosening Up Researchers have uncovered a key way that human and mosquito DNA are structured differently from one another — and figured out how to morph each into the other opposite arrangement. Working independently at first, two teams of scientists realized two important things about genomic structure: that some species, including mosquitoes, had loosely folded chromosomes while those of other

Updated at 3:51 p.m. on June 4, 2021. O n the night of May 17, at Target Field in Minneapolis, something terrible happened. It divided clubhouses, spawned a wrenching national conversation, resulted in fines and suspensions, and pitted a Hall of Fame manager against his own rookie outfielder, who had been one of the feel-good stories of this young MLB season—until that fateful night. All it took
In my experience, out here in the West, people are, by and large, aggrieved. This is not entirely their fault. Federal and state governments have made lots of promises to people in the West, or to their parents or grandparents. Some people were promised that their land would not be taken, while other people were promised free land. Some were told that they could withdraw water from this or that l
Squint the right way and things look almost normal. The barriers around the Capitol are gone. People are taking off their masks and going out. The Nats and Orioles are in the basement . Most of all, politics is boring again. That's not to say Washington is working well, mind you. Consider this week's negotiations between President Joe Biden and Senator Shelley Moore Capito of West Virginia, a Rep
According to a new study, cases of sexually transmitted infections (STIs) including chlamydia and gonorrhea could soon spike as the COVID-19 pandemic winds down. As we're heading what the media has referred to as " hot vax summer ," experts are worried that STIs could return with a vengeance. Researchers analyzed positivity rates based on data from over 18.6 million tests performed across the US
If new research is to be believed, doctors may someday be able to treat our injuries by helping our bodies regenerate damaged or missing tissue — just like a salamander regrowing its tail. A team of scientists found a critical difference in the way that the immune systems of an axolotl — an animal renowned for its ability to regenerate just about any part of its body — and that of a mouse, which

Forty years ago, astronomers using sensitive new imaging techniques discovered a class of large, faint galaxies they named low-surface-brightness galaxies. Giant low-surface-brightness galaxies (gLSBGs) are a subset whose masses are comparable to the Milky Way's but whose radii are ten times bigger, as much as four hundred thousand light-years. These gLSBGs raise a problem for astronomers: despite
The universe contains a mind-boggling number of stars—but scientists' best estimates may be an undercount. A NASA-funded sounding rocket is launching with an improved instrument to look for evidence of extra stars that may have been missed in stellar head counts.
Douglas Adams had a talent for irony. In the Hitchhiker's Guide series he told the tale of a civilization that tried to improve itself by tricking everyone with a useless job into taking a rocket trip to another world (actually to nowhere). For example, one of the discarded people's jobs was to clean phones. That's it – they were a phone cleaner. That civilization later collapsed due to a pandemi
A peculiar creature inhabits Washington, called the "institutionalist." The label—sometimes assigned, sometimes adopted—has been applied to characters as varied as Chief Justice John Roberts , Senator Dianne Feinstein , and President Joe Biden . Institutionalists tend to be veteran, aging members of a given government entity. They relish their reputations as defenders of hallowed traditions and n
For all of the recent advances in language AI technology, it still struggles with one of the most basic applications. In a new study , scientists tested four of the best AI systems for detecting hate speech and found that all of them struggled in different ways to distinguish toxic and innocuous sentences. The results are not surprising—creating AI that understands the nuances of natural language
Honeybee colony collapse is due in part to Varroa mites that weaken honey bee immune systems. Chemicals that were once effective against the mites are no longer working as well. Researchers are stepping in with a newly cultured fungus that goes after the mites without bothering the bees. Honey bees are vitally important to agriculture — by some estimates , they're responsible for pollinating more

Seeing images of Victorian era predictions of the year 2000, I see the mistakes they made. Mostly in the aesthetic being decidedly Victorian looking. Technology seems to minimize things more and more and make it easier and easier for lazy people to use. Society also becomes increasingly sexualized in the manner of dress. In the future by the year 3000, if the species still exists, people will lik
If you're wearing gold jewelry right now, there's a good chance it came from an illegal mining operation in the tropics and surfaced only after some rainforest was sacrificed, according to researchers who studied regulatory efforts to curb some of these environmentally damaging activities.
My wife, Deb, has written about the concept of " Big Little Ideas ." These are modest-seeming, simple-and-practical steps that can have surprisingly large consequences.

Facebook has responded to last month's much-hyped decision regarding the platform's removal of Donald Trump. The former president will not be allowed to return, the company said, until January 7, 2023—two years from the date of his original suspension. This is arguably a very long time, as well as arguably no time at all. It feels more like the latter if you consider when the 2024 presidential ho
A study of more than 1,000 demographically representative participants found that about 22 percent of Americans self-identify as anti-vaxxers, and tend to embrace the label as a form of social identity.
If you're wearing gold jewelry right now, there's a good chance it came from an illegal mining operation in the tropics and surfaced only after some rainforest was sacrificed, according to a team of University of Wisconsin-Madison researchers and alumni who studied regulatory efforts to curb some of these environmentally damaging activities in the Amazon.

Results from the Phase II cohort of the CodeBreaK 100 study showed that treatment with the KRAS G12C inhibitor sotorasib achieved a 37.1% objective response rate and 12.5 months median overall survival in previously treated patients with KRAS G12C-mutated non-small cell lung cancer (NSCLC), according to researchers from The University of Texas MD Anderson Cancer Center.
The new drug sotorasib reduces tumor size and shows promise in improving survival among patients with lung tumors caused by a specific DNA mutation, according to results of a global phase 2 clinical trial led by Washington University School of Medicine in St. Louis. The drug is designed to shut down the effects of the mutation, which is found in about 13% of patients with lung adenocarcinoma, a co
Population behavior, like voting and vaccination, depends on the structure of social networks. This structure can differ depending on behavior type and is typically hidden. However, we do often have behavioral data, albeit only snapshots taken at one time point. We present a method jointly inferring a model for both network structure and human behavior using only snapshot population-level behavio
Alongside the steep reductions needed in fossil fuel emissions, natural climate solutions (NCS) represent readily deployable options that can contribute to Canada's goals for emission reductions. We estimate the mitigation potential of 24 NCS related to the protection, management, and restoration of natural systems that can also deliver numerous co-benefits, such as enhanced soil productivity, cl
Quantum networks will provide multinode entanglement enabling secure communication on a global scale. Traditional quantum communication protocols consume pair-wise entanglement, which is suboptimal for distributed tasks involving more than two users. Here, we demonstrate quantum conference key agreement, a cryptography protocol leveraging multipartite entanglement to efficiently create identical
Sleep disturbances in autism and neurodevelopmental disorders are common and adversely affect patient's quality of life, yet the underlying mechanisms are understudied. We found that individuals with mutations in CHD8 , among the highest-confidence autism risk genes, or CHD7 suffer from disturbed sleep maintenance. These defects are recapitulated in Drosophila mutants affecting kismet , the sole
Soft untethered micromachines with overall sizes less than 100 μm enable diverse programmed shape transformations and functions for future biomedical and organ-on-a-chip applications. However, fabrication of such machines has been hampered by the lack of control of microactuator's programmability. To address such challenge, we use two-photon polymerization to selectively link Janus microparticle-
Balancing the biodegradability and mechanical integrity of a bioresorbable scaffold (BRS) with time after implantation to match the remodeling of the scaffolded blood vessel is important, but a key challenge in doing so remains. This study presents a novel intercalated structure of a metallic BRS by introducing a nanoscale Zn sacrificial layer between the nitrided Fe platform and the sirolimus-ca
When a peatland is drained and cultivated, it behaves as a notable source of CO 2 . However, we lack temporally and spatially explicit estimates of carbon losses from cultivated peatlands. Using a process-based land surface model that explicitly includes representation of peatland processes, we estimate that northern peatlands converted to croplands emitted 72 Pg C over 850–2010, with 45% of this
With increasing interest in the control of systems at the nano- and mesoscopic scales, studies have been focused on the limit of the energy dissipation in an open system by refining the concept of the Maxwell's demon. To uncover the underlying physical principle behind a system controlled by a demon, we prove a previously unexplored set of fluctuation theorems. These fluctuation theorems imply th
While a structural description of the molecular mechanisms guiding ribosome assembly in eukaryotic systems is emerging, bacteria use an unrelated core set of assembly factors for which high-resolution structural information is still missing. To address this, we used single-particle cryo–electron microscopy to visualize the effects of bacterial ribosome assembly factors RimP, RbfA, RsmA, and RsgA
Hepatocellular carcinoma (HCC) is driven by repeated rounds of inflammation, leading to fibrosis, cirrhosis, and, ultimately, cancer. A critical step in HCC formation is the transition from fibrosis to cirrhosis, which is associated with a change in the liver parenchyma called ductular reaction. Here, we report a genetically engineered mouse model of HCC driven by loss of macroautophagy and hemiz
The use of nanocrystal (NC) building blocks to create metamaterials is a powerful approach to access emergent materials. Given the immense library of materials choices, progress in this area for anisotropic NCs is limited by the lack of co-assembly design principles. Here, we use a rational design approach to guide the co-assembly of two such anisotropic systems. We modulate the removal of geomet
Two models have been put forward for cyclin-dependent kinase (Cdk) control of the cell cycle. In the qualitative model, cell cycle events are ordered by distinct substrate specificities of successive cyclin waves. Alternatively, in the quantitative model, the gradual rise of Cdk activity from G 1 phase to mitosis leads to ordered substrate phosphorylation at sequential thresholds. Here, we study
Calcium-sensing receptor (CaSR) is a class C G protein–coupled receptor (GPCR) that plays an important role in calcium homeostasis and parathyroid hormone secretion. Here, we present multiple cryo–electron microscopy structures of full-length CaSR in distinct ligand-bound states. Ligands (Ca 2+ and -tryptophan) bind to the extracellular domain of CaSR and induce large-scale conformational changes
Understanding single-molecule chemical dynamics of surface ligands is of critical importance to reveal their individual pathways and, hence, roles in catalysis, which ensemble measurements cannot see. Here, we use a cascaded nano-optics approach that provides sufficient enhancement to enable direct tracking of chemical trajectories of single surface-bound molecules via vibrational spectroscopy. A
Immunomodulatory drugs (IMiDs) have markedly improved patient outcome in multiple myeloma (MM); however, resistance to IMiDs commonly underlies relapse of disease. Here, we identify that tumor necrosis factor (TNF) receptor-associated factor 2 ( TRAF2 ) knockdown (KD)/knockout (KO) in MM cells mediates IMiD resistance via activation of noncanonical nuclear factor B (NF-B) and extracellular signal
South Asian precipitation amount and extreme variability are predicted to increase due to thermodynamic effects of increased 21st-century greenhouse gases, accompanied by an increased supply of moisture from the southern hemisphere Indian Ocean. We reconstructed South Asian summer monsoon precipitation and runoff into the Bay of Bengal to assess the extent to which these factors also operated in
Reprogramming of somatic cells into desired functional cell types by small molecules has vast potential for developing cell replacement therapy. Here, we developed a stepwise strategy to generate chemically induced neural crest cells (ciNCCs) and chemically induced corneal endothelial cells (ciCECs) from mouse fibroblasts using defined small molecules. The ciNCCs exhibited typical NCC features an
Typical sensors detect small perturbations by measuring their effects on a physical observable, using a linear response principle (LRP). It turns out that once LRP is abandoned, new opportunities emerge. A prominent example is resonant systems operating near N th-order exceptional point degeneracies (EPDs) where a small perturbation
Skin-like health care patches (SHPs) are next-generation health care gadgets that will enable seamless monitoring of biological signals in daily life. Skin-conformable sensors and a stretchable display are critical for the development of standalone SHPs that provide real-time information while alleviating privacy concerns related to wireless data transmission. However, the production of stretchab
RNase L is widely thought to limit viral protein synthesis by cleaving host rRNA and viral mRNA, resulting in translation arrest and viral mRNA degradation. Here, we show that the mRNAs of dengue virus and influenza A virus largely escape RNase L–mediated mRNA decay, and this permits viral protein production. However, activation of RNase L arrests nuclear mRNA export, which strongly inhibits infl

Among adults with kidney failure undergoing hemodialysis in New York City, Black and Hispanic patients were more likely to develop symptomatic COVID-19 than White patients. Neighborhood-level social vulnerability factors were associated with COVID-19 incidence among White patients, but these factors did not explain racial/ethnic disparities.
The global threat of ongoing climate change has one principal cause: carbon that was buried underground in the form of fossil fuels being removed and released into the atmosphere in the form of carbon dioxide (CO2). One promising approach to addressing this problem is carbon capture and storage: using technology to take CO2 out of the atmosphere to return it underground.
Engaged listening techniques such as eye contact, nodding and using key words to praise openness helps teenagers when they admit bad behaviour and share hurt feelings with their parents, a new study has shown.
The number of Australian PhD graduates reached around 10,000 a year in 2019, twice as many as in 2005. However, the number of PhDs has been exceeding the available academic positions since as early as the mid-1990s. In 2020, universities purged around 10% of their workforce due to the pandemic, and many university careers are still vulnerable . Given these statistics, you might wonder if doing a
Nature, Published online: 04 June 2021; doi:10.1038/d41586-021-01506-w Researchers added 200 million DNA base pairs and 115 protein-coding genes — but they've yet to entirely sequence the Y chromosome.
A genetic link has been discovered explaining why some people catch Covid but don't get sick. The gene is found three times as often in people who are asymptomatic.

Delicious to some, but a bitter bane to others' taste buds, vegetables like broccoli rabe, bok choy and turnips are a dinner staple — and picky eater conflict — around the world. It all likely started in the mountains near present-day Afghanistan, where humans first domesticated turnips 3,500 to 6,000 years ago, according to a new study recently published in the journal Molecular Biology and Evo
A new kind of prostate cancer treatment tested at Oregon Health & Science University combines a targeting compound with a radioactive isotope to irradiate and kill cancer cells, sparing most normal tissues.
Whenever someone disses agnosticism as pointless, bleak, or weak, Radiohead's 2001 song "I Might Be Wrong" starts playing in my head. A guitar riff conveys all the tension of a bar that's about to erupt into a brawl. Thom Yorke sings, in his meekest mumble, "I used to think there was no future left at all." That's an unsurprising confession from a notoriously gloomy bandleader, but it's paired wi
In A Little Life , a novel by the author Hanya Yanagihara, the tone is exaggerated, almost melodramatic . But the book brings nuance to a key realm—its portrayal of queerness—as its four protagonists each arrive at complex understandings of their sexuality. Indeed the best works of queer literature create space for this complexity. For example, the critic Andrea Long Chu questions simplistic narr
Kyushu University researchers find that one of the causes of CKD induced heart failures is the over expression of G protein-coupled receptor 68 in monocytes. Monocyte disruption was caused by the activation of the Clock gene, the key regulator of circadian rhythm via the increased level of vitamin A in the body resulting from kidney dysfunction.

Environmental change is happening so quickly that wild organisms can't keep up, and face substantial challenges. But some organisms may be able to adapt surprisingly rapidly to new circumstances. Predicting which species will be able to adapt quickly is far from straightforward, but an unassuming coastal plant may just hold the key to understanding how species adapt quickly to man-made habitats.
Our proteome is much bigger than our genome because one gene produces several variants of proteins called protein isoforms, whose disbalance is implicated in many diseases. A new bioengineered reporter system developed at Helmholtz Zentrum München and the Technical University of Munich now allows for the first time to follow protein isoform expression over time in live cells. The method helps to d
Conventional carbon capture is limited by high transportation costs and the need for intensive purification. Membrane-based direct air capture is a promising alternative because capture and storage can be performed at the same remote sites, and low CO2 purity is acceptable for geological storage because the impurities are not hazardous.

Those lakes represent about 69% of the Earth's freshwater habitats by volume. The researchers anal
The eruption of Mount Nyiragongo, an active volcano in the Democratic Republic of the Congo (DRC), led to the deaths of at least 30 people. There could however be longer term health implications for residents of the area. Patrick DMC Katoto, who has studied the health effects of volcanoes in the DRC, provides insights into the health risks that a volcanic eruption brings.
Ancient "medicine" once consisted of sacrificial offerings and divine petition. Disease was a supernatural infliction; health was a gift. Hippocrates invented medical science, and his theory of the humors and holistic health dominated Western medical thought for more than two thousand years. Today, medicine is much more disease centred, and perhaps something has been lost from the Hippocratic doc
Climate scientists at the Nanyang Technological University, Singapore (NTU, Singapore) have extended the known record of Singapore's sea level to almost 10,000 years ago, providing a more robust dataset to aid future predictions of sea level rise.
A team of scientists including a University of Michigan aquatic ecologist is forecasting this summer's Gulf of Mexico hypoxic area or "dead zone," an area of low to no oxygen that can kill fish and other marine life, to be approximately 4,880 square miles, a bit smaller than the state of Connecticut.
People are writing more than ever with their keyboards and phones, but handwritten notes have become rare. Even signatures are going out of style. Most credit card purchases no longer require them, and if they do, you can usually just scratch one out with your fingernail. The age-old art of handwriting is in decline.
Water is weird—and yet so important. In fact, it is one of the most unusual molecules on Earth. It boils at a temperature it shouldn't. It expands and floats when it is in the solid-state. Its surface tension is higher than it should be. Now, new research published in the journal Nature has added one other equally strange property to water's list of oddities. The implications of this new revelatio
Dispatching drones equipped with remote sensing technology in the air and taking smartphone images on the ground, a Michigan State University researcher is helping farmers more quickly predict and quantify tar spot, a disease found in maize crops.
Knowledge of the diets of New Zealand's extinct moa (Aves: Dinornithiformes) comes from careful analysis of moa coprolites (fossilized poop) and gizzard contents. Moa coprolites and gizzard contents can be dissected and analyzed under the microscope or using DNA identification techniques to decipher what the birds ate. The contents can also be screened to see what seeds the birds may have disperse
Sea ice thickness is inferred by measuring the height of the ice above the water, and this measurement is distorted by snow weighing the ice floe down. Scientists adjust for this using a map of snow depth in the Arctic that is decades out of date. In the new study, researchers swapped this map for the results of a new computer model designed to estimate snow depth as it varies year to year.
A team from the Centre for Earth Observation Science at the University of Manitoba has published a paper in the Nature journal Communications Earth & Environment that addresses a large gap in our understanding of Arctic Sea Ice coverage.

BioNyt Videnskabens Verden (www.bionyt.dk) er Danmarks ældste populærvidenskabelige tidsskrift for naturvidenskab. Det er det eneste blad af sin art i Danmark, som er helliget international forskning inden for livsvidenskaberne.
Bladet bringer aktuelle, spændende forskningsnyheder inden for biologi, medicin og andre naturvidenskabelige områder som f.eks. klimaændringer, nanoteknologi, partikelfysik, astronomi, seksualitet, biologiske våben, ecstasy, evolutionsbiologi, kloning, fedme, søvnforskning, muligheden for liv på mars, influenzaepidemier, livets opståen osv.
Artiklerne roses for at gøre vanskeligt stof forståeligt, uden at den videnskabelige holdbarhed tabes.
