Phys.org / Simulations map how single-crystal battery materials could boost cycle life
The performance of rechargeable batteries is governed by processes deep within their components. A fundamental understanding of electrochemistry, structure–property–performance relationships and the effects of processing ...
Medical Xpress / Weight-loss wonder pills prompt scrutiny of their key ingredient
Blockbuster weight-loss drugs are transforming the way we treat obesity. But while costly injectable versions remain out of reach for many, newly approved tablet forms are expected to significantly boost access and demand. ...
Phys.org / Ancient cone-shaped vessels may have served as beeswax lamps during ritual processions, study finds
Chalcolithic cornets are conical ceramic vessels produced exclusively during the Chalcolithic period, recovered in abundance at some archaeological sites but absent at others. Their function has long been debated. However, ...
Phys.org / Rising simultaneous wildfire risk compromises international firefighting efforts
The most high-risk conditions for fires are increasingly happening across countries at the same time, making resulting wildfires even more challenging to tackle, new research reveals.
Phys.org / Terahertz spectroscopy finds nitrogen can lengthen GaAs-like LO phonon decay
An Osaka Metropolitan University-led research team investigated the decay time of coherent longitudinal optical (LO) phonons both in a GaAs1−xNx epilayer and in a GaAs single crystal to clarify the effects of dilute nitridation.
Medical Xpress / Our brains may learn more from rare events than from repetition
More than a century ago, Pavlov trained his dog to associate the sound of a bell with food. Ever since, scientists have assumed the dog learned this through repetition. The more times the dog heard the bell and then got fed, ...
Phys.org / Does the motion of DNA influence its activity?
How does our DNA store the massive amount of information needed to build a human being? And what happens when it's stored incorrectly? Jesse Dixon, MD, Ph.D., has spent years studying the way this genome is folded in 3D space—knowing ...
Phys.org / How one molecule's 'voice' was captured: Infrared light meets scanning tunneling microscopy
When things vibrate, they make sounds. Molecules do too, but at frequencies far beyond human hearing. Chemical bonds stretch, bend, and twist at characteristic rates that fall in the infrared region of the electromagnetic ...
Phys.org / Why negativity can motivate founders: Study links doubts to greater persistence
A new study finds entrepreneurs become more committed to their business ventures when they are told they will fail, increasing their efforts to make those businesses successful. "Most entrepreneurs—people who start their ...
Phys.org / NASA conducts second rocket fueling test that will decide when Artemis astronauts head to the moon
NASA took another crack at fueling its giant moon rocket Thursday after leaks halted the initial dress rehearsal and delayed the first lunar trip by astronauts in more than half a century.
Phys.org / SpaceX launch to feature rare booster landing in Bahamas
It will be business as usual for SpaceX when it tries to send up a rocket from the Space Coast Thursday night, but not so much for when the rocket comes back down.
Phys.org / Warming winters are disrupting the hidden world of fungi—the result can shift mountain grasslands to scrub
When you look out across a snowy winter landscape, it might seem like nature is fast asleep. Yet, under the surface, tiny organisms are hard at work, consuming the previous year's dead plant material and other organic matter.
