Because of its long-term perspective on human–environment relationships, archaeology is well positioned to study how people respond to past climate change and natural disasters. In interpreting these relationships, archaeological perspectives have shifted from viewing people as passively reacting to environmental change, to instead focusing on human action, decision making, and…

The reduced development of COVID-19 for children compared to adults provides some tantalizing clues on the pathogenesis and transmissibility of this pandemic virus. First, ACE2, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) receptor, is reduced in the respiratory tract in children. Second, coronavirus associated with common colds in children…

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiological agent of COVID-19, is considered a zoonotic pathogen mainly transmitted human to human. Few reports indicate that pets may be exposed to the virus. The present report describes a cat suffering from severe respiratory distress and thrombocytopenia living with a family…

Landscape-scale reconstructions of ancient environments within the cradle of humanity may reveal insights into the relationship between early hominins and the changing resources around them. Many studies of Olduvai Gorge during Pliocene–Pleistocene times have revealed the presence of precession-driven wet–dry cycles atop a general aridification trend, though may underestimate the…

In humans and other long-lived species, harsh conditions in early life often lead to profound differences in adult life expectancy. In response, natural selection is expected to accelerate the timing and pace of reproduction in individuals who experience some forms of early-life adversity. However, the adaptive benefits of reproductive acceleration…

Modern practice for training classification deepnets involves a terminal phase of training (TPT), which begins at the epoch where training error first vanishes. During TPT, the training error stays effectively zero, while training loss is pushed toward zero. Direct measurements of TPT, for three prototypical deepnet architectures and across seven…

We used a combination of polarized Raman spectroscopy experiment and model magnetism–phonon coupling calculations to study the rich magneto-Raman effect in the two-dimensional (2D) magnet CrI3.

The oligoadenylate synthetase (OAS)–RNase L system is an IFN-inducible antiviral pathway activated by viral infection. Viral double-stranded (ds) RNA activates OAS isoforms that synthesize the second messenger 2-5A, which binds and activates the pseudokinase-endoribonuclease RNase L. In cells, OAS activation is tamped down by ADAR1, an adenosine deaminase that destabilizes…

Thousands of Down syndrome cell adhesion molecule (Dscam1) isoforms and ∼60 clustered protocadhrein (cPcdh) proteins are required for establishing neural circuits in insects and vertebrates, respectively. The strict homophilic specificity exhibited by these proteins has been extensively studied and is thought to be critical for their function in neuronal self-avoidance….

The failure of polypeptides to achieve conformational maturation following biosynthesis can result in the formation of protein aggregates capable of disrupting essential cellular functions. In the secretory pathway, misfolded asparagine (N)-linked glycoproteins are selectively sorted for endoplasmic reticulum-associated degradation (ERAD) in response to the catalytic removal of terminal alpha-link

Cell crawling requires the generation of intracellular forces by the cytoskeleton and their transmission to an extracellular substrate through specific adhesion molecules.

Drought alters carbon (C) allocation within trees, thereby impairing tree growth. Recovery of root and leaf functioning and prioritized C supply to sink tissues after drought may compensate for drought-induced reduction of assimilation and growth. It remains unclear if C allocation to sink tissues during and following drought is controlled…

Gleaners and exploiters (opportunists) are organisms adapted to feeding in nutritionally poor and rich environments, respectively. A trade-off between these two strategies—a negative relationship between the rate at which organisms can acquire food and ingest it—is a critical assumption in many ecological models. Here, we evaluate evidence for this trade-off…

Human decisions can be biased by irrelevant information. For example, choices between two preferred alternatives can be swayed by a third option that is inferior or unavailable. Previous work has identified three classic biases, known as the attraction, similarity, and compromise effects, which arise during choices between economic alternatives defined…

Size is a key to locomotion. In insects, miniaturization leads to fundamental changes in wing structure and kinematics, making the study of flight in the smallest species important for basic biology and physics, and, potentially, for applied disciplines. However, the flight efficiency of miniature insects has never been studied, and…

Controlling autonomous propulsion of microswimmers is essential for targeted drug delivery and applications of micro/nanomachines in environmental remediation and beyond.

Australian funnel-web spiders are infamous for causing human fatalities, which are induced by venom peptides known as δ-hexatoxins (δ-HXTXs). Humans and other primates did not feature in the prey or predator spectrum during evolution of these spiders, and consequently the primate lethality of δ-HXTXs remains enigmatic. Funnel-web envenomations are mostly…

Domesticated dogs show unparalleled diversity in body size across breeds, but within breeds variation is limited by selective breeding. Many heritable diseases of dogs are found among breeds of similar sizes, suggesting that as in humans, alleles governing growth have pleiotropic effects. Here, we conducted independent genome-wide association studies in…

While near-cognate codons are frequently used for translation initiation in eukaryotes, their efficiencies are usually low (<10% compared to an AUG in optimal context).

At a time when food production is one of the biggest climate culprits, it is essential that we seek out new food sources which can nourish us and, at the same time, not overburden the planet.

Man-made global heating has long been presented as a relatively simple chain of cause and effect: humans disrupt the carbon cycle by burning fossil fuels, thereby increase the concentration of CO2 in the atmosphere, which in turn leads to higher temperatures around the globe. "However, it becomes increasingly clear that this is not the end of the story. Forest fires become more frequent all over t

Under global warming, the frequent occurrence of summer heatwaves has exerted an increasing impact on human health and public infrastructure. For example, Europe experienced a severe heatwave in 2003 with more than 70,000 heat-related casualties. Western Russia was struck by its hottest summer on record in 2010, leading to the deaths of around 55,000 people. Record-breaking heatwaves have also bee

On June 5, 1944, four years into the German occupation of France during World War II, he was supposed to meet with fellow leaders in the French Resistance when his assistant, Geneviève Noufflard, told him that several commanders within the greater Paris region had just been caught by the Gestapo. Monod was pretty sure that at least one of thos

From the first rumblings of its spread, COVID-19's impact on women academics was immediate. In a sign of the gendered nature of the pandemic's impacts, men's research submissions to academic journals almost instantly increased by 50%, single-author articles by women dropped.

The phenomenon of hot dust rings—an accumulation of submicrometer-sized particles in the immediate vicinity of stars—was first discovered outside our solar system in 2006. They form so close to stars that they can reach temperatures of up to 1,000 degrees Celsius. However, the dust particles are difficult to observe due to their small size, and their origin is still unknown.

Scientists have re-investigated a sixty-year-old idea by an American physicist and provided new insights into the quantum world.

In theory, the particles could reveal whether a reactor is building up plutonium for weapons. US energy experts are starting to take the idea seriously.

Upgraded graphics and animations are a breath of fresh air, but old story tropes hold this remake back.

Quantum mechanics arose in the 1920s, and since then scientists have disagreed on how best to interpret it. Many interpretations, including the Copenhagen interpretation presented by Niels Bohr and Werner Heisenberg, and in particular, von Neumann-Wigner interpretation, state that the consciousness of the person conducting the test affects its result. On the other hand, Karl Popper and Albert Eins

There is a drive to displace fossil fuels in power generation and transport with sustainable alternatives. One approach that has been discussed over the last few decades is a future zero-carbon, hydrogen economy wherein hydrogen is generated from renewables and used to feed fuel cells in cars. Fuel cells are essentially electrical batteries that can be fed chemical energy continuously to generate

In normal times, Americans don't think much about democracy. Our Constitution, with its guarantees of free press, speech, and assembly, was written more than two centuries ago. Our electoral system has never failed, not during two world wars, not even during the Civil War. Citizenship requires very little of us, only that we show up to vote occasionally. Many of us are so complacent that we don't

I blame Michael Wolff. Not just for the typos and minor errors littering Fire and Fury , his early-2018 best seller on the chaos coursing through the Trump White House. Not only for the dubious renditions of reality his book offers.

'Risk of unemployment is highest during the first three to five years after diagnosis, so we need to be able to intervene early to prevent job losses, and their subsequent impact. This study points to factors related to risk of unemployment that may be amenable to early intervention. Professionals who provide MS care should be aware of the potential impact of this diagnosis on future employment, a

Similarities among individuals living in the same communities can dramatically change their risk of dying by suicide, according to a new study by Indiana University researchers.

Closed-canopy rainforests are a vital part of Earth's modern ecosystems, but tropical plants don't preserve well in the fossil record so it is difficult to tell how long these habitats have existed and where rainforests might have once grown. Instead, scientists look to the diets of extinct animals, which lock evidence of the vegetation they ate into their teeth. A new study finds that the paradig

Even when a person suffering from malaria is burning up with fever and too sick to function, the tiny blood-eating parasites lurking inside them continue to flourish, relentlessly growing and multiplying as they gobble up the host's red blood cells.
