"Sediment and fossil records are a major pillar of our understanding of how the climate works—but climate scientists have gotten something wrong about Australia's ice age," says Dr. Alex F. Wall, lead author of a new research paper published in Quaternary Science Reviews.
It's a common refrain that AI is changing how we work, but new research conducted by the Notre Dame-IBM Tech Ethics Lab, housed in the Institute for Ethics and the Common Good, shows that AI is creating new forms of work and reconfiguring employees' lived experience of work itself.
Humpback whale mothers may experience grief when their calves die, a rare research observation led by Griffith University and Sea World Foundation has found.
Nearly nine in 10 (86%) UK-licensed online gambling websites are operating in breach of the General Data Protection Regulation, according to new research from the Gambling Research, Education and Treatment (GREAT) Center at Swansea University published in the journal Computers in Human Behavior Reports.
The mammalian gut microbiome teems with a delicate balance of bacteria and the viruses that keep them in check, called bacteriophages, or phages. Each bacterial species usually has its own set of phage partners.
Soft materials such as colloidal suspensions, emulsions, foams and gels often display complex and unusual behaviors compared with ordinary solids or liquids. From a mechanical point of view, for instance, they can resist deformation like solids, but they can also start to flow like liquids when a sufficiently strong external drive is applied. This transition from solid-like to liquid-like behavior, known as "yielding," is central to the physics of soft amorphous materials and to many industrial and biological processes.
Astronomers have confirmed that one of the fastest-changing stars ever observed has entered a new stage of its evolution, offering a rare opportunity to watch a star's life unfold on human timescales.
The longest satellite record ever assembled shows that Greenland and Antarctica have lost 11.3 trillion metric tons of ice since the 1970s, raising global sea level by more than 3 centimeters (1.2 inches)—and that most of the loss has come from glaciers flowing faster into the ocean, not from melting at the surface.
Laser scanning, often referred to as lidar, has rapidly transformed how tropical forest regions are studied, monitored and understood across academic disciplines. The technology enables researchers to peer through dense forest canopies, rapidly providing high-resolution scans of the landscape below. This growing observational power is central to the scientific value of remote sensing technologies but also brings into focus the conditions, interests and power structures under which they are used.
Critically endangered Sumatran elephants are being pushed closer to the brink as wildfires raze vast swaths of their habitat on the western island of Sumatra, Indonesian conservation group Geopix told AFP on Wednesday.
SpaceX announced Tuesday that it was planning to send its flagship rocket, Starship, into orbit, a key step in its project to one day reach the moon or Mars.
The United States has confirmed for the first time that it has deployed weapons in space, a remarkable revelation after previous warnings about countries such as Russia possibly weaponizing a global frontier long agreed in treaties to be used for only peaceful purposes.
Brigid Lynch was working along a wooded creek in a mountainous part of the San Francisco Bay Area when something that didn't look like the rocks she'd been studying caught her eye. It turned out to be the fossilized tooth of a Pacific mastodon.
Scientists from Trinity College Dublin have developed a way to unravel changing weather patterns on distant worlds. Using this approach, they discovered that the weather on a well-studied brown dwarf, SIMP 0136, previously linked to northern lights-like phenomena, is largely shaped by just two dominant processes: changes in temperature and the vertical structure of its clouds.
A new national study reveals the widespread reach of violence across the United States, finding that more than half of U.S. adults have experienced physical violence and nearly half have experienced sexual violence in their lifetimes. The U.S. National Study on Violence Experiences Across the Lifespan (USVEX) also shows stark disparities in who experiences violence and how closely violence is linked to economic hardship, mental health and substance use.
Two-thirds of a century after Jane Goodall observed "David Greybeard" break off a twig to fashion a fishing rod for termites, researchers following in her footsteps have found that adult chimpanzees in Senegal literally hand youngsters the tools for learning.
According to research by the IfM Bonn, strengthening research collaboration between universities and businesses requires regional technology transfer networks in which technology transfer offices at universities and research institutions, as well as chambers of commerce and industry, trade associations, chambers of crafts, business-related networks and financial intermediaries, all play an active role. In this way, networking opportunities could be pooled and examples of good practice highlighted.
Smallholder farmers in sub-Saharan Africa adopt agricultural inputs, including fertilizer, at low rates, contributing to low agricultural productivity. Previous research has shown that insufficient information and distrust in the quality of products for sale in local markets are among the reasons for low rates of fertilizer adoption and application. In a new study published in the American Journal of Agricultural Economics, University of Illinois Urbana-Champaign researchers examined the agricultural marketplace in Tanzania, finding that frequent turnover among local agro-dealers affects farmer perceptions of product quality and has implications for broader market functioning.
Neurons in humans and other mammals express many exceptionally long genes, ranging from more than 100 kbp to more than 2 Mbp, that are important for forming synapses and neural circuits. In general, genetic information is read from DNA into RNA. This process is called transcription. The longer a gene is, the more time it takes to read from beginning to end. In addition, gene expression must be regulated at several steps. Neurons are therefore thought to require special mechanisms to read long genes accurately and stably, but the details of these mechanisms have remained unclear.
Light is traditionally described by properties such as wavelength, amplitude, phase and polarization. Advances in optics have shown that light can also be shaped into complex spatial patterns known as structured light, enabling new ways to carry information and interact with matter for applications in imaging, optical communications and information processing.
