Examination of Theia 456 finds its nearly 500 stars were born at same time
The Milky Way houses 8,292 recently discovered stellar streams—all named Theia. But Theia 456 is special.
Nanodiamond sensors can act as both heat sources and thermometers
A team of scientists from Osaka University, the University of Queensland and the National University of Singapore's Faculty of Engineering used tiny nanodiamonds coated with a heat-releasing polymer to probe the thermal properties of cells. When irradiated with light from a laser, the sensors acted both as heaters and thermometers, allowing the thermal conductivity of the interior of a cell to be...

Scientists identify nutrient that helps prevent bacterial infection
- ScienceDaily
- 21/1/15 19:53
Scientists studying the body's natural defenses against bacterial infection have identified a nutrient -- taurine -- that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn). The finding could aid efforts seeking alternatives to antibiotics.

Using state-of-the-art fabrication and imaging, researchers watched the consequences of adding sculpted light to a catalyst during a chemical transformation. This work could inform more efficient -- and potentially new -- forms of catalysis.
Using metals for fuel
Did you know that in microgravity we are preparing one of the most promising fuels for the future?
US fishing and seafood industries saw broad declines last summer due to COVID-19
While losses vary by sector, by region and by industry, data and information from this report may help businesses and communities assess losses and inform long-term recovery and resilience strategies.
Scientists identify nutrient that helps prevent bacterial infection
Scientists studying the body's natural defenses against bacterial infection have identified a nutrient—taurine—that helps the gut recall prior infections and kill invading bacteria, such as Klebsiella pneumoniae (Kpn). The finding, published in the journal Cell by scientists from five institutes of the National Institutes of Health, could aid efforts seeking alternatives to antibiotics.
Towards applications: ultra-low-loss on-chip zero-index materials
A refractive index of zero induces a wave vector with zero amplitude and undefined direction. Therefore, light propagating inside a zero-index medium does not accumulate any spatial phase advance, resulting in perfect spatial coherence. Such coherence brings several potential applications, including arbitrarily shaped waveguides, phase-mismatch-free nonlinear propagation, large-area single-mode...
New study compiles four years of corn loss data from 26 states and Ontario, Canada
Plant pathologists working at universities across 26 corn-producing states in the United States and in Ontario, Canada, compiled data about annual corn reductions caused by diseases. Estimated loss from each disease varied greatly by region.
Engineers find a way to control chemical catalysts with sculpted light
Like a person breaking up a cat fight, the role of catalysts in a chemical reaction is to hurry up the process—and come out of it intact. And, just as not every house in a neighborhood has someone willing to intervene in such a battle, not every part of a catalyst participates in the reaction. But what if one could convince the unengaged parts of a catalyst to get involved? Chemical reactions...

Vampire finches: how little birds in the Galápagos got a taste for big bird blood
For most people, the word "vampire" brings to mind Dracula or perhaps slayers such as Blade or Buffy; or maybe even the vampire bats of South America. Few will think of a small and rather lovely bird—the finch.
Cities can help migrating birds on their way by planting more trees and turning lights off at night
Millions of birds travel between their breeding and wintering grounds during spring and autumn migration, creating one of the greatest spectacles of the natural world. These journeys often span incredible distances. For example, the Blackpoll Warbler, which weighs less than half an ounce, may travel up to 1,500 miles between its nesting grounds in Canada and its wintering grounds in the Caribbean...

How hitchhiking worms choose their vehicles
Tiny worms that live inside fig trees use the fig wasp as a 'vehicle' to hitch rides from one tree to another by crawling into the wasp's gut without harming it. This relationship has existed for millions of years. But how do these worms‒called nematodes‒choose their wasp vehicles? What cues do they use to check for co-passengers? A new study from the Centre for Ecological Sciences (CES) at...

Physicists propose a new theory to explain one dimensional quantum liquids formation
Liquids are ubiquitous in Nature: from the water that we consume daily to superfluid helium which is a quantum liquid appearing at temperatures as low as only a few degrees above the absolute zero. A common feature of these vastly different liquids is being self-bound in free space in the form of droplets. Understanding from a microscopic perspective how a liquid is formed by adding particles one...
Large mammals make soil more fertile in tropical forests
The White-lipped peccary (Tayassu pecari) is a boar-like hoofed mammal found throughout Central and South America. These animals roam the forest in bands of 50 to 100 individuals, eating a wide variety of foods. In Brazil's Atlantic Rainforest, they prefer the fruit of the jussara palm Euterpe edulis.
