Medical Xpress / Scientists create first-ever 'smell map' of the nose's smell receptors
For most of us, the sense of smell is an integral part of everyday life; it plays a critical role in providing information about our surroundings, alerting us to potential dangers, enhancing our sense of taste, and evoking ...
Phys.org / Airborne desert dust may warm climate far more than expected, new analysis shows
Atmospheric dust plays a dual role in Earth's climate: it reflects some sunlight back into space while also absorbing and retaining the planet's heat like an insulating blanket. But while dust likely cools the planet overall, ...
Phys.org / Stick-on gel delivers drugs directly to plants to clear infections quickly
A stick-on gel for plants could one day offer a simple, safe and targeted way to treat diseases and pests. Engineers at the University of California San Diego have developed an adhesive gel that can be loaded with substances, ...
Tech Xplore / AI 'deadbots' can fuel pathological grief and affect how we deal with death
Due to recent developments in artificial intelligence (AI), it's now possible to digitally "revive" dead people and interact with them.
Medical Xpress / Cellular pathways may underlie some differences in physical fitness
Patterns of molecular activity in the blood may hold clues not only to how fit someone is, but also to the biological processes that support physical performance. Researchers at MIT, GE HealthCare, and the U.S. Military Academy ...
Phys.org / Two whale groups separated by seas—but not by genes, study finds
A paper in Genome Biology and Evolution discovers that the endangered Mediterranean fin whale is not completely isolated from Atlantic groups. Both Atlantic and Mediterranean populations have declined for the past 200,000 ...
Medical Xpress / B-cell clusters inside kidneys mark faster diabetic disease progression, new maps reveal
A detailed new map of the human kidney revealed a previously unrecognized form of diabetic kidney disease (DKD) marked by clusters of immune cells—specifically B cells—that are linked to faster disease progression. The findings ...
Phys.org / New study details changing US irrigated agriculture, viability strategies
A new study by researchers at the Daugherty Water for Food Global Institute at the University of Nebraska offers a comprehensive national-scale assessment of irrigated agriculture in the United States in recent years. Published ...
Medical Xpress / Digital twin can reveal alcohol consumption in crime cases
Using a so-called digital twin, it is possible to predict with greater precision than at present how much alcohol a person has consumed and at what time. The study was conducted by researchers at Linköping University and ...
Phys.org / Q&A: Prediction markets are surging—here's what you need to know
Stanford scholar and former SEC Commissioner Joseph Grundfest shares insights on prediction markets, which are gaining popularity amid concerns over regulation and potential manipulation.
Phys.org / Soil, not fertilizer, is primary source of nitrogen gas loss in rice paddies, study reveals
Rice production is heavily dependent on nitrogen fertilizers, particularly in China, where application rates are two to three times the global average. At the same time, a large amount of nitrogen is lost to the environment—mainly ...
Phys.org / Tiny DNA fragments, big agricultural insights: New genomic approach helps improve crop resilience
The genes that could help the world's crops survive drought, heat, and disease probably already exist. But much of this genetic diversity remains hidden within ancient plant varieties and forgotten seed collections, among ...
