When the U.S. Federal Reserve announces a change in its interest rate, consumers expect shifts in borrowing costs elsewhere and potential price adjustments for things like housing and some consumer goods. New research, however, shows that stock market analysts generally give a collective
Typically, after a physical system is disturbed, it can gradually return toward a state of thermal equilibrium by exchanging heat with its surroundings. Thermal equilibrium is a state in which there is no net transfer of heat between the system and its surroundings.
University of Queensland researchers have shown tiny crystals are a window to activity inside volcanoes and could provide clues to when they might erupt.
To understand how societies might react to climate change, archaeologists look at social responses to extreme climate events in the past
Researchers at the University of Tokyo have used a new type of radiocarbon analysis to study a sediment core taken from the Kumano Sea off the coast of Japan. This has revealed multiple
Researchers from Kyushu University have found that H3mm15, a histone H3.3 subvariant, contributes to normal sperm development in mice by helping regulate gene expression during spermatogenesis. The findings show that H3mm15 cannot be interchanged with conventional H3.3; although the proteins differ at only three amino acids, they behave differently in chromatin, the DNA-protein structure that packages genetic material.
A research team led by professor Seong Sik Shin of the SKKU Advanced Institute of Nanotechnology (SAINT) at Sungkyunkwan University (SKKU), in international collaboration with the Korea Research Institute of Chemical Technology (KRICT), the University of California, San Diego, and Princeton University, has developed a next-generation perovskite semiconductor thin film with dramatically reduced defects. Using the same material platform, the researchers demonstrated both high-performance solar cel
Using the James Webb Space Telescope (JWST), a team of astronomers identified 104 magnified stellar events in a galaxy known as the Dragon, located around 6.5 billion light-years away. This discovery more than doubles the previous record of 44 such detections in the same galaxy. Because these kinds of events reveal some of the most luminous stars and likely the presence of dark matter, this study offers a rare look at the galaxy

A huge coral colony stretching more than 1.5 kilometers (0.93 miles) along the outer reef of the Cocos (Keeling) Islands has been identified by researchers, making it one of the largest known coral colonies ever recorded.
In 2009, researchers working in the Liang Bua cave on Flores Island came across a leg bone. The 190,000
Fourier transforms are mathematical calculations that can be used to identify the frequencies that make up a signal and shed light on their individual contributions. These transforms have been used, for example, to unveil patterns in sounds and images, ranging from gradual changes in intensity to fine repeating motifs or details.
The search for extraterrestrial intelligence (SETI) is mostly concerned with where to look for technosignatures from another civilization. Between 2012 and 2015, SETI
Want to fly to the moon and help build a permanent lunar base? NASA is accepting applications for a new astronaut class that will help grow the Artemis program.
A Florida chimpanzee sanctuary had to deliver food to one of its 200 apes by drone this week because the property was swamped by heavy rain. But the animals stayed safe, and the water finally was receding significantly on Saturday, the organization said.
Tropical ecosystems are famous for their teeming, exuberant diversity. In fact, the dramatic increase in biodiversity from the poles to the tropics
Private retirement savings are an increasingly important topic in public debate. One popular idea is to phrase savings reminders in one of two ways: either you emphasize what someone stands to lose if they don
Armed with dozens of motion-sensing cameras, William Grooms spent this past summer documenting wildlife across Carson National Forest in northern New Mexico. It was his first field season collecting photos for a two-year study to understand how forest structure influences biodiversity in the Southern Rocky Mountains.
There are at least 14 million insect species on Earth, and they play highly diverse roles in sustaining the natural world. Insects provide many well-known benefits
An academic abstract, a blog post and a public outreach article all place different demands on the writer. Readers
In a new Nature Physics study, researchers demonstrated the Aharonov-Bohm effect in a quantum simulation of a lattice gauge theory using a hybrid trapped-ion quantum computer.
The Mediterranean Sea still holds species unknown to science. One of them is Copula lucentia, a tiny jellyfish measuring just a few millimeters. Discovered off El Campello, in Alicante, it was formally described in 2024 by a research team at the University of Alicante (UA) Marine Laboratory in D
Glaciers are often thought of as unyielding blocks of ice that slowly carve out the landscape as they move downhill by gravity. But sometimes their slow crawl becomes a surge that sees them move orders of magnitude faster than their usual speed.
Medieval health and sanitation efforts involved deliberate interventions; however, some of these measures had the opposite effect, leading to an increased spread of disease in Trondheim.
An alternative model in which the universe is 26.7 billion years old and needs neither dark matter nor dark energy has held up against several major cosmology tests, according to a new University of Ottawa study. The research, titled
To protect their future harvests, Western Canadian farmers need to manage soil acidity across their entire multiyear rotation rather than crop by crop, long-term research from the University of Alberta suggests.
For people across South Asia, especially in northern India, Diwali celebrations coincide with the return of hazardous winter air, raising concerns about how to celebrate safely.
Meteorologists said Friday they were observing an unprecedented early disruption of the polar vortex, raising the risk of cold snaps across the Northern Hemisphere, though there remains significant uncertainty.

Few insects have a more gruesome lifestyle than Darwin wasps. Rather than simply hunting other animals, these parasitic wasps lay their eggs on or inside living hosts, including caterpillars, beetles and spiders. Their larvae then feed on their hosts, gradually consuming them and eventually killing them.
Traditional lenses and mirrors focus light using curved surfaces. Metasurfaces can achieve similar functions with a flat layer of nanoscale structures that locally control the phase of light. Extending these flat optics into the ultraviolet could support compact systems for high-resolution imaging, spectroscopy, and sensing, but it introduces a fundamental materials problem: many of the materials used to make metasurfaces strongly absorb UV light.
Metabolites are consumed by enzymes to produce other vital molecules as well as to control metabolite levels. But how do cells avoid consuming too much? Researchers from the MPI of Biochemistry, with the University of Nevada, Las Vegas, and the de Duve Institute in Brussels, have deciphered such molecular regulation in tryptophan metabolism. The essential amino acid tryptophan binds to a second site on the enzyme TDO2, distinct from where it is consumed. This sequesters a region needed by two ef
Microplastics have been found in our bodies and the food we eat
The extreme heat waves we have seen over the last few years may only serve as a preview of what is to come as a result of climate change. A new study led by researcher Philipp Aglas-Leitner from Freie Universit
Throughout the drug development process, which can take a decade or more, tens of thousands of chemical compounds are produced that never go on to become medicines. A Florida State University researcher is part of a team that has discovered a new way to give some of these
For the first time, an international team of researchers from Germany, Thailand, India, China and the United States has created a three-component Hubbard system with tunable interactions in the laboratory. In doing so, the team used a quantum gas microscope to make the individual atoms visible. The study, published in Science, provides an important foundation for future quantum simulations of nuclear physics and materials science.
