Biosensors mimic human olfactory system to discriminate between very similar odors
The human olfactory system discriminates between thousands of odors by interacting specifically with olfactory receptors on sensory neurons. Each receptor can detect several odorants at different intensities, and the same odorant can activate more th.....»»
Digital labels can help grocers waste less food
In 2022, U.S. grocers wasted 5 million tons of food, with 35% of it going to landfills, according to the food waste nonprofit ReFed. More than half of that waste—2.7 million tons—was past the labels' expiration dates......»»
Professor challenges tokenizing women of color in academia
The unspoken rule for women of color in academia is to be everything to everyone—mentor, diversity champion, tireless scholar, and silent workhorse, says York University equity studies Assistant Professor Yvonne Su in her paper published in Nature.....»»
Avalanches, icy explosions and dunes: NASA is tracking New Year on Mars
Instead of a winter wonderland, the Red Planet's northern hemisphere goes through an active—even explosive—spring thaw. While New Year's Eve is around the corner here on Earth, Mars scientists are ahead of the game: The Red Planet completed a tri.....»»

Neural networks unlock potential of high-entropy carbonitrides in extreme environments
The melting point is one of the most important measurements of material properties, which informs potential applications of materials in various fields. Experimental measurement of the melting point is complex and expensive, but computational methods.....»»
The science behind Christmas trees: How conifers brave winter"s worst
As the festive season approaches, evergreen conifers like spruce and pine adorn homes worldwide. But while Christmas trees bring warmth and joy into our lives, they endure some of the harshest conditions on Earth in their natural habitats......»»
Grapevine protein resembles animal ion transport function, researchers discover
Researchers at the University of Adelaide have discovered that a protein which mediates the transport of alkali metal ions, such as potassium, and halide ions across plant membranes acts similarly to a protein found in animals......»»
Warming exacerbates oxygen depletion in the Baltic Sea, undermining nutrient reduction efforts
Eutrophication and rising water temperatures are taking an increasing toll on the Baltic Sea, leading to dangerous oxygen depletion in deeper water layers and threatening many marine organisms. Despite successful efforts to reduce nutrient inputs, ri.....»»
Intense ribbons of rain also bring the heat, scientists say
The environmental threat posed by atmospheric rivers—long, narrow ribbons of water vapor in the sky—doesn't come only in the form of concentrated, torrential downpours and severe flooding characteristic of these natural phenomena. According to a.....»»
Genetically encoded biosensors measure living cells" charge in real time
Biological cells have many vital functions in the organism. For example, they produce proteins, carbohydrates and fats. But they are also responsible for detoxifying harmful molecules and transmitting signals and immune defense steps. A so-called red.....»»
Global study reveals phenological divergence between plants and animals under climate change
A collaborative study reveals the distinct mechanisms by which plants and animals respond to climate change in their life-cycle phenology. This research, led by Piao Shilong's team and Zhang Yao's team from the Institute of Carbon Neutrality at Pekin.....»»
First results from 2021 rocket launch shed light on aurora"s birth
Results from a 2021 experiment led by a University of Alaska Fairbanks scientist have begun to reveal the particle-level processes that create the type of auroras that dance rapidly across the sky......»»
Scientists steer the development of stem cells to regenerate and repair organs
Investigators from Cedars-Sinai and the University of California, San Francisco (UCSF) have identified a new way to deliver instructions that tell stem cells to grow into specific bodily structures, a critical step in eventually regenerating and repa.....»»
The microbiology of honey: A sweet symphony of life
Honey, a complex substance made by a variety of species of bees, is often celebrated for its sweetness and health benefits. In fact, humans have been using honey, sometimes called liquid gold, for generations to soothe cold symptoms and promote wound.....»»
Dripstones from Romanian cave offer insights into climate dynamics in Europe
Investigations into precipitation patterns in eastern Central Europe since the end of the last ice age, conducted by an international research team led by Dr. Sophie Warken of Heidelberg University, have shown that dynamic processes in atmospheric ci.....»»
Dark energy "doesn"t exist" so can"t be pushing "lumpy" universe apart, physicists say
One of the biggest mysteries in science—dark energy—doesn't actually exist, according to researchers looking to solve the riddle of how the universe is expanding......»»
The technosphere: A hidden long-term carbon sink in everyday items
