Tiny Big Bang: ALICE experiment restarts with lead ions
On September 26, 2023, the accelerator team at the CERN European Council for Nuclear Research in Geneva declared stable lead-beam conditions, ushering in the first data-taking campaign of lead-ion collisions in five years. From then until the late ev.....»»
Some of the moon"s craters are from interstellar impacts. Can we tell which?
By discovering two interstellar objects (ISOs), we know that asteroids and comets from other star systems pass through the solar system from time to time. By inference, some of these must have crashed into the moon, creating impact craters. If we cou.....»»
Study finds link between school desegregation and midlife cognitive function
Exposure to state-level school desegregation during primary school was associated with higher midlife cognitive function among Black Americans who grew up in the U.S. South from the 1950s to 1970s, according to new findings by a University of Marylan.....»»
Dangerous bee virus less deadly in at least one US forest, researchers find
This year's cold and flu season is bringing good news for honey bees. Penn State researchers have found that the deadly deformed wing virus (DMV) may have evolved to be less deadly in at least one U.S. forest. The findings could have implications for.....»»
Social-behavioral findings can be highly replicable, six-year study by four labs suggests
Roughly two decades ago, a community-wide reckoning emerged concerning the credibility of published literature in the social-behavioral sciences, especially psychology. Several large scale studies attempted to reproduce previously published findings.....»»
Eavesdropping on the electron: A new method for extracting data from noise
A method developed at the University of Duisburg-Essen makes it possible to read data from noisy signals. Theoretical physicists and their experimental colleagues have published their findings in the current issue of Physical Review Research. The met.....»»
Webb findings support long-proposed process of planet formation
Scientists using James Webb Space Telescope just made a breakthrough discovery in revealing how planets are made. By observing water vapor in protoplanetary disks, Webb confirmed a physical process involving the drifting of ice-coated solids from the.....»»
Study shows what kind of salt we use on the roads in winter can make a difference for plants
Increased salinity in soils is a global problem caused, for example, by ions leaching into soils from ice-melting salts used on roads in winter or from seawater seepage in coastal areas......»»
Scientists observe composite superstructure growth from nanocrystals in real time
For the first time, scientists and engineers have observed in real time how two types of nanoparticles made from different materials combine into new composite materials. The findings, reported by a team led by the University of Pennsylvania and Univ.....»»
Producing stronger, tougher silk by feeding silkworms with rare earth ion-modified diets
A research team led by Dr. Yingying Zhang (Department of Chemistry, Tsinghua University) devised a scheme utilizing silkworms to produce strong, tough silk through feeding them with rare earth ion-modified diets. The rare earth ions can be incorporat.....»»
Letting those leaves pile up? New research shows leaf litter contains persistent free radicals
Research led by environmental health sciences (ENHS) associate professor Eric Vejerano has found that leaves are a source of biogenic persistent free radicals (BPFRs). Vejerano and Ph.D. in ENHS alumna Jeonghyeon Ahn published their findings in Envir.....»»
Researchers reveal hidden sensory mechanism of hair follicles
Imperial researchers have discovered a hidden mechanism within hair follicles that allow us to feel touch. The findings have been published in Science Advances......»»
Scientists demonstrate the existence of a universal lower bound on topological entanglement entropy
In a new study, scientists from the US and Taiwan have theoretically demonstrated the existence of a universal lower bound on topological entanglement entropy, which is always non-negative. The findings are published in the journal Physical Review Le.....»»
Agronomists find green way to mitigate the effects of soil salinity
Most crops are sensitive to soil salinity. Excess salts cause salt stress—plants lack water, photosynthesis is suppressed, respiration worsens, chlorophyll breaks down, and potassium ions leak. Water-soluble toxic salts stimulate the synthesis of r.....»»
Multimodal graphene-based e-textiles for the realization of customized e-textiles developed for the first time
A joint research team led by Principal Researcher Soongeun Kwon and Professor Young-Jin Kim has developed graphene-based, customized e-textiles, for the first time in the world. They published their findings in ACS Nano in a paper titled, "Multimodal.....»»
Sexual harassment and stereotyping: How coastal sciences are failing women in the field
New research published in Cambridge Prisms: Coastal Futures looking at the experiences of women working in coastal sciences worldwide has unearthed important and disturbing findings......»»
Scientists uncover cause of mysterious deaths of elephants in Zimbabwe
A bacterium, closely associated with deadly septicemia, could have caused the deaths of six African elephants in Zimbabwe and possibly more in neighboring countries. The findings place infectious diseases on the list of pressures on African elephants.....»»
Examining the synergistic roles of platinum nanoparticles and sodium ions within beta zeolites
