A cooperative approach to reproductive success
Fertilization is often imagined as a frantic race, with millions of sperm competing for a single prize. But new research by a team of evolutionary biologists from Syracuse University, the University of Siena in Italy and the University of Szeged in Hungary reveals a more
Newly unearthed mechanism that helps plants 'feel full' could help crops use fertilizer more efficiently
New York University researchers have pinpointed the molecular players responsible for plants "feeling full" once they've taken up enough nitrogen—a finding that could help scientists develop plants that absorb more nitrogen from the soil and allow farmers to reduce
How simple amber lights could make nights safer for insects
Approximately 40% of insect species worldwide are thought to be in decline and under threat of extinction. Among the key causes are habitat loss, pollution and climate change. Another threat is artificial light from sources like streetlights and security lamps. In new research
Climate change could dramatically reduce water flowing from the West's headwaters
The small mountain streams that feed many of the West's rivers may face a much drier future. A new study led by NAU researchers found that groundwater-fed streamflow, known as base flow, has been steadily declining across headwater watersheds in the western United States since
New microscopy method achieves angstrom-scale localization precision with one laser
Researchers in the lab of Sam Peng, the Pfizer Inc.–Gerald Laubach Career Development Assistant Professor of Chemistry at MIT and a core institute member of the Broad Institute of MIT and Harvard, have developed a super-resolution imaging technology. It allows scientists to
Antibiotic resistance is spreading through South Africa's water systems. This study explains how
Antimicrobial resistance (AMR) is defined as the ability of disease-causing microorganisms to withstand treatments like antibiotics.
Webb reveals warped structure in nearby TW Hydrae's protoplanetary disk
Using the James Webb Space Telescope (JWST), astronomers obtained high-contrast coronagraphic images of the protoplanetary disk around the young, nearby star TW Hydrae. Results of the observational campaign, published July 27 on the preprint server arXiv, shed more light on the
Supergene solves evolutionary puzzle of mirror-image flowers
The left-right asymmetry of South African butterfly lilies (genus Wachendorfia) has been regarded as a classic evolutionary puzzle for more than a century. Due to the mirror-image arrangement of the floral parts, the plants achieve efficient cross-pollination. The molecular
Why some nitrogen-processing enzymes are more efficient than others
Nitrogen gas is abundant in Earth's atmosphere, but most living organisms can't readily use it. Only a subset of microbes with enzymes known as nitrogenases can break nitrogen gas apart and convert it into ammonia.
Laid to rest with care: Ancient infants, perhaps twins, found in 1,200-year-old latrine
More than 1,000 years ago, two babies were tucked away in an abandoned Roman toilet channel. Yet, despite what the location suggests, they were cherished, not discarded.
AI use mirrors student schedules in study of 77,000 online learners
How do students actually use AI learning assistants? A new research paper by IU International University of Applied Sciences provides the first robust answers to this question. For the study "Using AI-based Learning Assistants in Higher Education: A Large-Scale Descriptive
Forever chemicals and pesticides under Trump: what to know
Since returning to power, President Donald Trump's administration has approved five pesticides considered by many to be PFAS "forever chemicals," a class of toxic substances facing bans and increasing restrictions around the world.
Dark matter’s secret force does the opposite of what scientists expected
Dark matter particles may exert a hidden force on one another, but its effects are stranger than expected. An extra attraction helps the particles cluster, yet it also makes dark matter effectively lighter as the Universe expands. That weakens its gravitational impact and
Without this protein, damaged muscle turns to fat and scar tissue
A protein once thought to mainly protect chromosome ends may also be essential for keeping muscle stem cells ready to repair injuries. Researchers found that TRF2 helps these cells maintain their identity and coordinate the cycle of rest, repair, and renewal.
Mathematicians prove perfectly fair elections are impossible
Mathematicians have shown that no electoral system can perfectly balance local representation, proportional national results, and a fixed-size parliament once enough parties compete. A newly proposed voting method could soften these unavoidable trade-offs and produce outcomes
Smart sensor identifies present molecules by remembering the past
Most sensors are designed to do only one thing: detect what passes through them. But what if a sensor could do more? To create a new generation of technology, researchers have looked to living systems for inspiration. If a sensor could detect molecules, could it also remember
DESI side project reveals the spectra of disintegrated exoplanets
Using spectral data from the Dark Energy Spectroscopic Instrument (DESI), astronomers have gained some of the clearest evidence yet that white dwarf stars are accreting debris from disintegrating exoplanets. Captured while DESI was unable to study its primary targets: distant
Indigenous territory maintains ecological stability amid agricultural expansion in the Brazilian savanna
"An island of biodiversity in a sea of monoculture": This is how a recent study characterized the Pimentel Barbosa Indigenous Territory (TIPB), located in the northeastern part of Mato Grosso state in Brazil's Central-West region. The study showed that the area's human
Pine bark and sponge compounds could counter drug-resistant malaria and babesiosis
As parasites become increasingly resistant to existing drugs, researchers at the University of California, Riverside, are working to develop a new generation of treatments for two serious infectious diseases: malaria and babesiosis.
This once-a-week workout may help cut belly fat, study shows
A surprisingly small dose of exercise may deliver major health benefits for adults carrying excess fat around the waist. In a four-month trial involving 315 adults with central obesity, researchers found that completing 75 minutes of brisk interval walking in a single weekly
Eating less protein could slow aging, major review finds
A sweeping review of more than 350 studies suggests that the protein boom may be overselling what many people actually need. Eating less protein appears to improve metabolism, reduce inflammation and cellular damage, and activate pathways linked to healthier aging and longer
Cancer may be breaking its own DNA to keep growing
Cancer cells rely on powerful genetic switches to keep growth genes running at full speed, but that intense activity can damage their own DNA. The resulting breaks are repeatedly repaired, sometimes with small mistakes that allow new mutations to accumulate. Researchers believe
Mysterious Milky Way object accelerates protons beyond one quadrillion electron volts
Scientists have identified LHAASO J1912+1014u as a cosmic accelerator that can push protons beyond one quadrillion electron volts. The finding may help reveal where the Milky Way’s most energetic cosmic rays come from and how they influence the galaxy.
Fluorescent probes offer sharper view of plant tissues
Researchers at the Indian Institute of Technology Gandhinagar (IITGN) and the Regional Centre for Biotechnology, Faridabad, have developed and tested a new class of fluorescent probes that enable scientists to visualize xylem, the specialized tissue responsible for transporting
How new informatics tools help turn biodiversity data into policy insights
Biodiversity loss has been among the central topics in public, policy and scientific debate for several decades. While its accelerating pace and impacts are well recognized, translating the vast amounts of biodiversity data into reliable indicators that can inform policy
