Stellar feedback and an airborne observatory; scientists determine a nebula younger than believed Posted: 13 Apr 2021 02:07 PM PDT Researchers studied RCW 120 to analyze the effects of stellar feedback, and found that RCW 120 must be less than 150,000 years old, which is very young for such a nebula.

Amoeba biology reveals potential treatment target for lung disease Posted: 13 Apr 2021 09:10 AM PDT In a series of experiments that began with amoebas -- single-celled organisms that extend podlike appendages to move around -- scientists say they have identified a genetic pathway that could be activated to help sweep out mucus from the lungs of people with chronic obstructive pulmonary disease a widespread lung ailment.

Elusive particle may point to undiscovered physics Posted: 13 Apr 2021 09:10 AM PDT The muon is a tiny particle, but it has the giant potential to upend our understanding of the subatomic world and reveal an undiscovered type of fundamental physics.

No batteries? No sweat! Wearable biofuel cells now produce electricity from lactate Posted: 13 Apr 2021 08:40 AM PDT Wearable electronic devices and biosensors are great tools for health monitoring, but it has been difficult to find convenient power sources for them. Now, a group of scientists has successfully developed and tested a wearable biofuel cell array that generates electric power from the lactate in the wearer's sweat, opening doors to electronic health monitoring powered by nothing but bodily fluids.

Atom interferometry demonstrated in space Posted: 13 Apr 2021 08:40 AM PDT A team of scientists has managed to successfully perform atom interferometry in space - on board a sounding rocket.

Smell you later: Exposure to smells in early infancy can modulate adult behavior Posted: 13 Apr 2021 08:06 AM PDT The smells that newborn mice are exposed to affect many social behaviors later in life, but how this happens is still a mystery. Scientists have now discovered the molecules necessary for imprinting.

A molecule that responds to light Posted: 13 Apr 2021 08:06 AM PDT Light can be used to operate quantum information processing systems, e.g. quantum computers, quickly and efficiently. Researchers have now significantly advanced the development of molecule-based materials suitable for use as light-addressable fundamental quantum units. They have demonstrated for the first time the possibility of addressing nuclear spin levels of a molecular complex of europium(III) rare-earth ions with light.

Megafauna extinction mystery: Size isn't everything Posted: 13 Apr 2021 06:54 AM PDT The rapid extinction of giant animals including wombat-like creatures as big as cars, birds more than two metres tall, and lizards more than seven metres long that once roamed the Australian continent is a puzzle that has long engaged researchers.

Frog species with 6 sex chromosomes offer new clues on evolution of complex XY systems Posted: 13 Apr 2021 05:13 AM PDT The O. swinhoana frog species is the first vertebrate known to retain descendant genes that now determine sex in mammals, birds, and fishes inherited from a common ancestor.

Scientists watch 2D puddles of electrons emerge in a 3D superconducting material Posted: 12 Apr 2021 04:42 PM PDT The emergence of 2D puddles of superconductivity within a 3D superconductor may be an example of how 3D superconductors reorganize themselves just before undergoing an abrupt shift into an insulating state. It also suggests a novel and potentially easier way to make 2D materials.

Plastic planet: Tracking pervasive microplastics across the globe Posted: 12 Apr 2021 01:19 PM PDT Really big systems, like ocean currents and weather, work on really big scales. And so too does your plastic waste, according to new research.

Amounts of organic molecules in planetary systems differ from early on Posted: 09 Apr 2021 07:44 AM PDT An international group of scientists have studied the chemical composition of 50 protoplanetary-disk forming regions in the Perseus Molecular Cloud, and found that despite being in the same cloud, the amounts of complex organic molecules they contain are quite different.
