Astronomers discover the most metal-poor extreme helium star
Using the Southern African Large Telescope (SALT), astronomers have performed high-resolution observations of a recently detected extreme helium star designated EC 19529–4430. It turned out that EC 19529–4430 is the most metal deficient among the.....»»
Clumps of an otherwise non-toxic molecule inhibit strep"s DNA-cleaving enzymes, researchers discover
An entirely new approach to inhibiting DNA-cleaving enzymes works through the aggregation of an otherwise non-toxic molecule. This Kobe University discovery may lead to a much-needed method for curbing Streptococcus growth......»»
Astronomers" simulations support dark matter theory
Computer simulations by astronomers support the idea that dark matter—matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe—exists, according to the resear.....»»
Researchers reveal water-assisted oxidative redispersion of metal nanoparticles
Oxidative redispersion at elevated temperatures has long been utilized in heterogeneous catalysis for the regeneration of sintered metal catalysts and the synthesis of metal single atom and cluster catalysts. These redispersion processes require a co.....»»
Gene seekers discover atypical genes that control multiple valuable soybean traits
A team led by Purdue University soybean geneticist Jianxin Ma has developed a new biotechnological tool for the domestication of desirable traits from wild soybeans, such as resistance to leafhopper insect pests. The use of such tools, called de novo.....»»
Researchers discover new lantibiotic produced by staphylococci
Researchers at the University Hospital Bonn (UKB), the University of Bonn, and the German Center for Infection Research (DZIF) have discovered a new lantibiotic, namely epilancin A37. It is produced by staphylococci that colonize the skin and act spe.....»»
Neutron stars could be capturing primordial black holes
The Milky Way has a missing pulsar problem in its core. Astronomers have tried to explain this for years. One of the more interesting ideas comes from a team of astronomers in Europe and invokes dark matter, neutron stars, and primordial black holes.....»»
Tibetan plateau had broader social dimensions than previously thought, suggests study
The Tibetan plateau—the world's highest and largest plateau—poses a challenge to the people who live there because of its extreme climate. In a new study, researchers have discovered stone artifacts that suggest that there were more cultural exch.....»»
Q&A: How to catch a glimpse of a new star about to appear in the night sky
If you peer up at the constellation Corona Borealis—the Northern Crown—over the next several months, you may catch a glimpse: Astronomers predict that sometime this year, a new star will appear in the night sky, growing as bright as the North Sta.....»»
People put greater trust in news that leads them to be more politically extreme, says study
People not only think political news is likelier to be true if it reinforces their ideological biases, but will tend to trust news more if it leads them to adopt more extreme (and even incorrect) beliefs, finds a new study by a UCL researcher......»»
"Sour Patch" adults: 1 in 8 grown-ups love extreme tartness, study shows
For most people, biting into a lemon would leave them puckered up and desperate to lose that sour flavor, but a new study by Penn State researchers revealed that roughly one in eight adults like intensely sour sensations. The cross-cultural study, re.....»»
Plant science research paves the way for deeper understanding of how the plant immune system functions

Tidal disruption event ASASSN-19bt experiences unusual radio evolution, observations show
An international team of astronomers has conducted detailed radio and X-ray observations of a tidal disruption event (TDE) designated ASASSN-19bt. Results of the observational campaign, presented April 18 on the pre-print server arXiv, shed more ligh.....»»
Orion"s erupting star system reveals its secrets
An unusual group of stars in the Orion constellation have revealed their secrets. FU Orionis, a double star system, first caught astronomers' attention in 1936 when the central star suddenly became 1,000 times brighter than usual. This behavior, expe.....»»
When does a conductor not conduct? Switching a 2D metal-organic framework from an insulator to a metal
An Australian-led study has found unusual insulating behavior in a new atomically-thin material—and the ability to switch it on and off......»»
