Earlier this month, I pulled a mask out of the bin of hats, scarves, and gloves I keep by the door; strapped it on; and choked. I had inhaled a mouthful of cat hair—several weeks' worth, left by my gray tabby, Calvin , who has been napping on a nest of face coverings since I largely dispensed with them in May. I've been fully vaccinated for two months . I spent the end of spring weaning myself of
Using the Atacama Large Millimetre/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, astronomers have unambiguously detected the presence of a disk around a planet outside our Solar System for the first time. The observations will shed new light on how moons and planets form in young stellar systems.
Back in December 2020, DeepMind took the world of biology by surprise when it solved a 50-year grand challenge with AlphaFold , an AI tool that predicts the structure of proteins. Last week the London-based company published full details of that tool and released its source code. Now the firm has announced that it has used its AI to predict the shapes of nearly every protein in the human body , a
The discovery of a Roman road submerged in the Venice Lagoon is reported in Scientific Reports this week. The findings suggest that extensive settlements may have been present in the Venice Lagoon centuries before the founding of Venice began in the fifth century.

Based on the analysis of marsquakes recorded by NASA's InSight mission, the structure of Mars's crust has now been determined in absolute numbers for the first time. Beneath the InSight landing site, the crust is either approximately 20 or 39 kilometers thick. That is the result of an international research team led by geophysicist Dr. Brigitte Knapmeyer-Endrun at the University of Cologne's Insti
A critical challenge in meeting the Paris Agreement's long-term goal of keeping global warming well below 2 degrees Celsius is to vastly reduce carbon dioxide (CO2) and other greenhouse gas emissions generated by the most energy-intensive industries. According to a recent report by the International Energy Agency, these industries—cement, iron and steel, chemicals—account for about 20 percent of g
Last week, CDC Director Rochelle Walensky said that COVID-19 is " becoming a pandemic of the unvaccinated ." President Joe Biden said much the same shortly after. They are technically correct. Even against the fast-spreading Delta variant , the vaccines remain highly effective, and people who haven't received them are falling sick far more often than those who have. But their vulnerability to COV

Reduced mobility induced by the COVID-19 restrictions had only minor influence on particulate pollution levels, according to atmosphere studies in the Po Valley region of northern Italy. Eventually computer simulations indicated that the change in air quality led to an increase in secondary aerosol formation.
Researchers report the first structural confirmation that endogenous — or self-made — molecules can set off innate immunity in mammals via a pair of immune cell proteins called the TLR4-MD-2 receptor complex. The work has wide-ranging implications for finding ways to treat and possibly prevent autoimmune diseases such as multiple sclerosis and antiphospholipid syndrome.
New research has uncovered the early assembly of gamma-secretase, a protein complex linked to numerous cellular processes including the development of Alzheimer's disease. In a first step, two dimeric subcomplexes are formed, which independently exit the ER and only afterwards assemble into a four-subunit complex. This 'buckle up' mechanism is thought to prevent premature assembly and activity.
To meet an ambitious goal of carbon neutrality by 2045, California's policymakers are relying in part on forests and shrublands to remove CO2 from the atmosphere, but researchers at the University of California, Irvine warn that future climate change may limit the ecosystem's ability to perform this service.
Lower winds and better weather helped crews using bulldozers and helicopters battling the nation's largest wildfire in southern Oregon while a Northern California wildfire crossed into Nevada, prompting new evacuations as blazes burn across the West.
Researchers at ETH Zurich working together with an international team have been able to use seismic data to look inside Mars for the first time. They measured the crust, mantle and core and narrowed down their composition. The three resulting articles are being published together as a cover story in the journal Science.
A simple exercise of naming unrelated words and then measuring the semantic distance between them could serve as an objective measure of creativity, according to a new study. Can you think of three words that are completely unrelated to one another? What about four, five, or even ten? The new study uses the Divergent Association Task (DAT), a 4-minute, 10-word test to measure one aspect of creati
For much of human history, animals and plants were perceived to follow a different set of rules than the rest of the universe. In the 18th and 19th centuries, this culminated in a belief that living organisms were infused by a non-physical energy or "life force" that allowed them to perform remarkable transformations that couldn't be explained by conventional chemistry or physics alone.
While many people are interested in switching to solar energy, the process can be very intimidating. Despite the fact that solar power is now cheaper than it's ever been, it's still a major investment, and it certainly doesn't make sense for every home. And with so many different variables, making the right choice can seem daunting. But if you're asking yourself, "is solar worth it," the experts
Scientists have shown that cockatoos, an iconic Australian bird species, learn from each other a unique skill — lifting garbage bin lids to gather food. The research confirms that cockatoos spread this novel behavior through social learning. This behavior by cockatoos is actually learnt, rather than a result of genetics.
I have a cellphone built into my watch. People now take this type of technology for granted, but not so long ago it was firmly in the realm of science fiction. The transition from fantasy to reality was far from the flip of a switch. The amount of time, money, talent, and effort required to put a telephone on my wrist spanned far beyond any one product development cycle. The people who crossed a
A new method that analyzes how individual immune cells react to the bacteria that cause tuberculosis could pave the way for new vaccine strategies against this deadly disease, and provide insights into fighting other infectious diseases around the world.
A new study, led by University of Minnesota Twin Cities engineering researchers, shows that the stiffness of protein fibers in tissues, like collagen, are a key component in controlling the movement of cells.

Superconducting electrodynamic qubits involve macroscopic numbers of electrons and offer the advantage of larger coupling, whereas semiconductor spin qubits involve indiv
For 2 years, the InSight lander has been recording seismic data on Mars that are vital to constrain the structure and thermochemical state of the planet. We used observations of direct ( P and S ) and surface-reflected ( PP , PPP , SS , and SSS ) body-wave phases from eight low-frequency marsquakes to constrain the interior structure to a depth of 800 kilometers. We found a structure compatible w
A planet's crust bears witness to the history of planetary formation and evolution, but for Mars, no absolute measurement of crustal thickness has been available. Here, we determine the structure of the crust beneath the InSight landing site on Mars using both marsquake recordings and the ambient wavefield. By analyzing seismic phases that are reflected and converted at subsurface interfaces, we
Clues to a planet's geologic history are contained in its interior structure, particularly its core. We detected reflections of seismic waves from the core-mantle boundary of Mars using InSight seismic data and inverted these together with geodetic data to constrain the radius of the liquid metal core to 1830 ± 40 kilometers. The large core implies a martian mantle mineralogically similar to the
Most optoelectronic devices operate at high photocarrier densities, where all semiconductors suffer from enhanced nonradiative recombination. Nonradiative processes proportionately reduce photoluminescence (PL) quantum yield (QY), a performance metric that directly dictates the maximum device efficiency.

Adenosine monophosphate (AMP)–activated protein kinase (AMPK) regulates metabolism in response to the cellular energy states. Under energy stress, AMP stabilizes the active AMPK conformation, in which the kinase activation loop (AL) is protected from protein phosphatases, thus keeping the AL in its active, phosphorylated state. At low AMP:ATP (adenosine triphosphate) ratios, ATP inhibits AMPK by
Plant nucleotide-binding leucine-rich repeat receptors (NLRs) regulate immunity and cell death. In Arabidopsis , a subfamily of "helper" NLRs is required by many "sensor" NLRs.

NASA's Perseverance rover has been playing second fiddle to the Ingenuity helicopter in recent months. But in fairness, it's a helicopter on Mars . Not to be outdone, Perseverance is gearing up for the next big step in its mission on the red planet. In the coming weeks, NASA will harvest the first of many samples that could one day return to Earth for study. First, the rover has to find just the
When it comes to cars, the technology competition between batteries and hydrogen has been won. The future of cars appears to be battery technology . There are some hydrogen-fueled cars, but they are a tiny slice of the market. The bottom line is that batteries are more efficient than hydrogen, and they are only going to get better. Volkwagen pretty much declared a victor with this statement : "Th
Researchers are working to develop a low-cost, practical biopolymer dressing that helps heal chronic wounds. Tens of millions of patients around the world suffer from persistent and potentially life-threatening wounds. These chronic wounds, which are also a leading cause of amputation, have treatments, but the cost of existing wound dressings can prevent them from reaching people in need. "The ex
Magnetic fields can be used to stimulate blood vessel growth, according to a study published in the journal Science and Technology of Advanced Materials. The findings, by researchers at the Tecnico Lisboa and NOVA School of Science and Technology in Portugal, could lead to new treatments for cancers and help regenerate tissues that have lost their blood supply.
Over the last forty years, the agricultural intensification, as well as the urban and farming development in the Lleida Plain, have reduced the expansion and quality of the available habitat for the steppe birds of this area, which covers a great part of species of such kind in Spain. The report on the State of Nature in Catalonia shows that this is one of the most threatened bird groups in the te
Remote sensing—beginning with aerial photography—has been used for decades in one form or another in archaeology, but, the discussion on the ethical use of the information gathered through these methods is a newer topic, according to a team of researchers.
In a study of college-educated biracial men, ages 18 to 32, sociolinguist Nicole Holliday found that, when asked about race, this group frequently brought up law enforcement unprompted and discussed the subject using vocal tone more generally associated with white speakers.
In 1399, a crowd gathered in the Tuscan city of Pisa, even though people understood that a plague ravaging the area was contagious. Devotees traveled from town to town and carried a crucifix—a sculpture of Jesus on the cross —which the crowd longed to touch.
Some materials used in aerospace applications such as polymers can degrade and erode with prolonged exposure to atomic oxygen, ultraviolet radiation, and extreme temperature cycling in the outer space. Also, because orbiting spacecraft such as the International Space Station travel at approximately 18,000 miles per hour, micrometeoroids and other space debris pose serious threats to the integrity
Many applications, from fiber-optic telecommunications to biomedical imaging processes require substances that emit light in the near-infrared range (NIR). A research team in Switzerland has now developed the first chromium complex that emits light in the coveted, longer wavelength NIR-II range. In the journal Angewandte Chemie, the team has introduced the underlying concept: a drastic change in t
North America's Basin and Range Province is home to some of the most extreme environments on the continent, including Death Valley. Stretching from the Wasatch Mountains in Utah to the Sierra Nevada in California and into northwestern Mexico, this area experiences near-constant drought and extreme summer heat.
