Phys.org / Converting CO₂ into valuable chemicals in acidic environments: Iodide ions unlock efficient ethylene production
The emission of carbon dioxide (CO₂) is one of the primary factors contributing to air pollution and climate change on Earth. In recent years, energy engineers have thus been trying to develop systems that could reduce ...
Phys.org / Cypriot fishermen battle invasive lionfish and turn them into a tavern delicacy
Photis Gaitanos' rough fingers adroitly untangle the venomous spikes of a lionfish from a net, throwing the exotic-looking creature into an ice-filled rubber bin along with other fish from the day's catch.
Medical Xpress / Gut bacteria may play role in bipolar depression by directly influencing brain connectivity
Bipolar disorder (BD) is a psychiatric disorder characterized by extreme mood changes. Individuals diagnosed with BD typically alternate between periods of high energy, euphoria, irritability and/or impulsivity (i.e., manic ...
Phys.org / The gut bacteria that put the brakes on weight gain in mice
The gut microbiome is intimately linked to human health and weight. Differences in the gut microbiome—the bacteria and fungi in the gut—are associated with obesity and weight gain, raising the possibility that changing ...
Phys.org / Scientists chart over 140,000 DNA loops to map human chromosomes in the nucleus
One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature.
Phys.org / Anything-goes 'anyons' may be at the root of surprising quantum experiments
In the past year, two separate experiments in two different materials captured the same confounding scenario: the coexistence of superconductivity and magnetism. Scientists had assumed that these two quantum states are mutually ...
Phys.org / How the global fish trade is spreading 'forever chemicals' around the world
Eating fish may well be good for you, but it carries a hidden risk of exposure to so-called "forever chemicals." A new study published in the journal Science has revealed that the global seafood trade is acting as a massive ...
Medical Xpress / Indoor tanning makes youthful skin much older on a genetic level
Tanning bed users are known to have a higher risk of skin cancer, but for the first time researchers have found that young indoor tanners undergo genetic changes that can lead to more mutations in their skin cells than people ...
Phys.org / Two ancient human species came out of Africa together, not one, suggests new study
The textbook version of the "Out of Africa" hypothesis holds that the first human species to leave the continent around 1.8 million years ago was Homo erectus. But in recent years, a debate has emerged suggesting it wasn't ...
Phys.org / The simulation hypothesis: Mathematical framework redefines what it means for one universe to simulate another
The simulation hypothesis—the idea that our universe might be an artificial construct running on some advanced alien computer—has long captured the public imagination. Yet most arguments about it rest on intuition rather ...
Medical Xpress / New study suggests best way to stop taking antidepressants
The best way for people with depression to stop taking antidepressants once their condition improves is to slowly taper off the medication while also receiving psychological support, new research suggested Thursday.
Phys.org / Iraqis cover soil with clay to curb sandstorms
Deep in Iraq's southern desert, bulldozers and earthmovers spread layers of moist clay over sand dunes as part of a broader effort to fight increasingly frequent sandstorms.
