Medical Xpress / Teenagers are getting far less sleep now than they did in late 2000s, finds new study
Eight hours of sleep used to be the norm, and all-nighters with only a few hours of rest were rare among teenagers. In recent years, however, there has been an alarming decline in sleep duration. It has reached a point where ...
Phys.org / Largest known Mesozoic crocodyliform egg clutch discovered in Brazil
In a study published in the Journal of Vertebrate Paleontology, researchers Dr. Giovanna M. X. Paixão and her colleagues analyzed the fossilized remains of three Upper Cretaceous egg clutches. One of these clutches, totaling ...
Phys.org / AI disclosure labels may do more harm than good, study warns
The growing use of AI-generated scientific and science-related content, especially on social media, raises important concerns: these texts may contain false or highly persuasive information that is difficult for users to ...
Tech Xplore / New ultra-low-cost technique could slash the price of soft robotics
Engineers at Oxford University have developed a rapid, ultra-low-cost method for manufacturing soft robots using common lab equipment. The method has been published in Advanced Science. The new technique enables researchers ...
Phys.org / Engineered magnetic films follow graphene's equations for massless electron waves
The electronic and magnetic properties of two-dimensional materials both have strong potential for technological applications. Researchers have long assumed that they are distinct phenomena, but Illinois Grainger engineers ...
Phys.org / How a protein pair ensures that faulty mRNA is destroyed
Nonsense-mediated mRNA decay (NMD) is one of the most important processes in our cells to ensure that no faulty or incomplete proteins are produced. Scientists have now identified a central mechanism behind this control system.
Phys.org / 'Mesoscale' swimmers could pave way for drug delivery robots inside the body
In physics, the mesoscale lies between the microscopic and the macroscopic. It is not just the domain of tiny living creatures like small larvae, shrimp, and jellyfish, but also where physics equations become extreme. While ...
Phys.org / How long does it take to get last liquid drops from kitchen containers? These physicists know the answer
At some point, most people have found themselves holding a tilted carton of milk or bottle of cooking oil, patiently waiting for the last drops to drip out. Now, physicists at Brown University have done the math to show just ...
Phys.org / Twenty-nine years of warming linked to soil fungi shift in Colorado plots
Long-term ecosystem warming changes not only plants but the fungi in the soil below, according to a new study including researchers from the University of Tennessee, Knoxville. "Hidden mycorrhizal fungi below ground are ...
Phys.org / Philippines' 'Cockroach Lord' goes to bat for misunderstood bugs
A thin band of light from Cristian Lucanas's headlamp pierces the blackness of a Philippine rainforest as he digs through the underbrush before gently scooping up a cockroach with his bare hands.
Phys.org / V615 Vul shows rare hybrid nova signature after rapid two-day rise
Italian astronomers have performed extensive spectroscopic monitoring of a recently discovered nova known as Vulpeculae 2024, also known as V615 Vul. Results of the new observations, presented in a paper published in the ...
Phys.org / Heat-tolerant corals may help some reefs persist, but most still erode
A recent report on global tipping points warned that coral reefs face widespread dieback and have reached a point from which they cannot recover.
