Science, engineering, and discovery — the research and breakthroughs that matter.

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 Analys

"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 occupation

Unusual metal oxide shows signs of magnetism under lattice strain in ultrathin layers and more — today's student signal.

Ruthenium dioxide (RuO2) is a metal oxide that commonly serves as an important metallic conductor, quantum material and industrial electrocatalyst. While there have been debates surrounding the magnetic properties of RuO2, it is generally thought to be nonmagnetic in its bulk for

Global warming appears to have shifted into a faster gear. After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with just under 0.2°C per decade fro

Ant parenting may have evolved from the same brain systems that once controlled hunger. Researchers found that two chemical signals push clonal raider ants toward either caring for larvae or leaving to forage, with the balance changing as the ants grow older. Similar signals are

Xenophagocytosis is a natural immune process that limits interspecies organ generation by eliminating living donor cells, researchers at the Institute of Science Tokyo, Japan, report. By uncovering how embryonic macrophages eliminate living donor cells, the researchers developed

Strengthening El Nino 'adding fuel to a planet already on fire': UN chief and more — today's student signal.

A strengthening El Niño that could shatter all-time records is "adding fuel to a planet already on fire" and pushing the world into "uncharted territory," U.N. Secretary-General Antonio Guterres warned Friday.

Finding water on the moon may only be a matter of detecting the right vibrations.

New wildfires fed by strong winds broke out in Greece on Friday, giving firefighters little respite and forcing Civil Protection officials to order the partial evacuation of part of a suburb west of Athens.

A new Concordia study has demonstrated a greener way to produce an important class of catalytic materials with promising potential for cleaner energy technologies that rely more on acoustic energy than water and chemicals. The work is published in the journal Advanced Synthesis &

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 pu

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 19

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 visua

Antimicrobial resistance (AMR) is defined as the ability of disease-causing microorganisms to withstand treatments like antibiotics.

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 n

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 basis

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.

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.

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 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 usually

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 tha
