Atomic diffusion technique could lead to mass production of metal nanowires
A group from Nagoya University in Japan has created a new technique for growing the tiny metal nanowires (NWs) that are expected to be used in next-generation electronics. Their results suggest a way to mass produce pure metal NWs, which has until no.....»»
Pausing biological clock could give boost to lab-produced blood stem cells
A decade ago, Raquel Espin Palazon discovered that inflammatory signaling pathways must switch on for embryos to produce blood stem cells. The latest work from her lab shows the potential value of keeping those same signals switched off after their i.....»»
Researchers reveal performance boost mechanism in single-atom catalyst for oxygen evolution reaction
Hydrogen energy, with its green, low-carbon and high-calorific-value properties, is emerging as the new key to solving the energy crisis. Electrochemically, water splitting has garnered much attention as a promising hydrogen production technique. How.....»»
Green hydrogen: MXenes show talent as catalyst for oxygen evolution reaction
The MXene class of materials has many talents. An international team led by HZB chemist Michelle Browne has now demonstrated that MXenes, properly functionalized, are excellent catalysts for the oxygen evolution reaction in electrolytic water splitti.....»»
Angiosperms study provides insights into genome evolution after whole-genome duplications
Whole-genome duplication (WGD, or polyploidy) is a common and frequent occurrence in plants, providing raw genetic material for evolution. Homoeologs (duplicate genes from a WGD) often diverge in expression levels, while some still maintain similar (.....»»
The world"s fastest single-shot 2D imaging technique films ultrafast dynamics in flames
Candle flames and airplane engines produce tiny soot particles from polycyclic aromatic hydrocarbons (PAHs) as their precursors, both of which are harmful to humans and the environment. These carbon-based particles are also common in space, making up.....»»

Whole genome duplications linked to higher oil yields in key crops
Oil crops are pivotal for human nutrition and industry due to their ability to produce and store large amounts of oil in seeds. With the global demand for vegetable oils steadily rising, there is an urgent need to discover new high-yielding oil plant.....»»
Double-peaked supernovae offer clues to pre-supernova outbursts
New research helps in understanding the evolution and final stages of massive stars, the role of binary interactions, and the mechanisms behind mass loss, which ultimately affect the properties of the resulting supernova and its remnant. This work al.....»»
Sony Bravia Theater Bar 9 review: a bare-bones soundbar with brilliant sound
Sony's newest flagship soundbar can produce impressive sound for movies and shows, but its lack of extra features makes us question its high price......»»
AI tool maps out cell metabolism with precision

Tuberculosis under the sea: A marine sponge microbe provides insights into the bacterium"s evolution
The surprising discovery of a bacterium in a marine sponge from the Great Barrier Reef with striking similarity to Mycobacterium tuberculosis, the pathogen responsible for tuberculosis (TB), could unlock and inform future TB research and treatment st.....»»
Spectroscopy study reveals electrons in cocatalyst periphery drive photocatalytic hydrogen evolution
Synchronizing periodic excitations of photocatalysts with a Michelson interferometer on operando FT–IR spectroscopy, researchers led by Toshiki Sugimoto succeeded in observing and identifying the reactive electron species for photocatalytic hydroge.....»»
Vinegar vapor method could make UV sensors 128,000 times more responsive
Researchers at Macquarie University have developed a new way to produce ultraviolet (UV) light sensors, which could lead to more efficient and flexible wearable devices......»»
Climate change will increase foodborne illness risk from raw produce, research suggests
Climate change will increase the risk of foodborne illness from Salmonella enterica, according to a new study. The research appears in Applied and Environmental Microbiology......»»
Larger ant colonies drive the evolution of worker castes: Division of labor is key to life"s complexity, says study
Just like human societies, ant societies have a division of labor. Within a colony, some individuals feed the young while others are soldiers who protect the colony from intruders. New research across 794 ant species, published in Nature Ecology & Ev.....»»
Land-sea "tag-team" devastated ocean life millions of years ago, reveal scientists
Scientists have revealed how a "tag-team" between the oceans and continents millions of years ago devastated marine life—and altered the course of evolution on Earth......»»
Safeguarding produce from E. coli contamination
Leafy greens such as spinach and lettuce are among the most nutrient-packed foods we can eat—and some of the most prone to make us miserable, or worse. The pathogenic bacterium Escherichia coli O157:H7 causes millions of illnesses globally each yea.....»»
From rhino horn snuff to pangolin livestock feed: A half-century of patents reveals the wildlife trade"s evolution
