Phys.org / A backup fluoride defense in soil bacteria could aid greener chemical production
Researchers at the University of Tartu have discovered a mechanism in bacteria that helps them adapt to fluoride, which is toxic to most organisms above relatively low threshold concentrations. Their discovery may represent ...
Phys.org / Math shows why your vote may not count the way you think it does
Mathematicians have shown that completely fair elections are—in a sense—impossible. No electoral system can guarantee both that local votes translate directly into local seats and that total seat distribution matches overall ...
Phys.org / Randomly mixed atoms arranged in rows and columns for sustainable catalysis
The energy system of the future will require sustainable catalysts that, for example, enable the efficient production of green hydrogen. Materials consisting of mixtures of five chemical elements show great promise for enabling ...
Phys.org / Modified cell vesicles trigger 'lipid counterstorm' against lung inflammation in mice
The COVID-19 pandemic highlighted severe consequences of unchecked respiratory disease, including cytokine storms. This phenomenon affected many COVID-19 patients and is a potential side effect of many other diseases involving ...
Phys.org / Inverting the seminar to recover what scientific papers leave out
A scientific paper reads as a clean progression from question to result. And yet, research almost never happens that way. Experiments fail, conversations redirect projects, and none of it survives into print. When the founders ...
Phys.org / Only 1 in 3 people arrested by ICE have a criminal conviction, research reveals
Just 34% of people arrested by the U.S. Immigration and Customs Enforcement agents during President Donald Trump's second term have a criminal conviction, according to research published in the Proceedings of the National ...
Phys.org / Chemists unlock Appel fluorination with potassium fluoride
Alcohols are among the most abundant building blocks in chemistry. Fluorinated compounds, meanwhile, are essential for many modern medicines, crop protection products and advanced materials. Converting one into the other, ...
Phys.org / New technique pinpoints human DNA inherited from 'ghost' ancestors
UC Berkeley researchers have identified regions of DNA that humans inherited from two unknown ancestors as a result of long-ago interbreeding among modern humans and at least four other archaic human relatives.
Phys.org / Physicists link the Riemann Hypothesis to phase transitions in quantum systems
A new study in Nature Communications has established a link between the Riemann Hypothesis and dynamical phase transitions in engineered quantum systems, demonstrating the effect on a quantum processor.
Phys.org / Hiroshima blast debris reveals a previously unknown alloy
The Hiroshima blast on Aug. 6, 1945, was one of the most devastating events in human history. Like all nuclear detonations, it created fleeting moments of extreme heat, pressure, mixing and cooling. These conditions can briefly ...
Phys.org / Physicists create Bose–Einstein condensate from ultracold polar molecules
Bose–Einstein condensates are states of matter that form when particles called bosons are cooled to temperatures that are only a fraction of a degree above absolute zero (i.e., 0 Kelvin [-460°F]). In these states, particles ...
Phys.org / Rainfall across the US is increasingly coming from farther away
Before rain falls, the moisture that forms it may have traveled anywhere from just a few kilometers to hundreds or even thousands of kilometers away. It usually begins as water that evaporated from oceans, lakes, forests ...
