Medical Xpress / Male sex hormones may protect lungs from asthma by boosting nerve connections
The differences in male and female sex hormones are most evident during growth, puberty and reproduction, when they help shape how the body develops and functions. Beyond their more visible effects, these chemical messengers ...
Phys.org / Cellular 'glue' helps epithelial tissues engulf dead cells while staying sealed
A protein that sticks cells and tissues together has been found to have a surprising second job: helping cells that are packed into a continuous sealed layer, also known as epithelial cells, engulf nearby dead cells.
Phys.org / Some Galápagos 'yellow' sea turtles remain homebodies, surprising scientists
Sea turtles are famous for being prodigious wanderers. Guided by Earth's magnetic field, ocean currents and the sun, they tend to crisscross the seas in search of food, returning to the region of their birth every few years ...
Phys.org / Fleeting sugar pairs may help curb abnormal cell-growth signals
Acting as armor, a scaffold and a communication platform in one, our cells' plasma membrane lies at the heart of many crucial cellular processes. Traditionally, it has been thought to function through interactions among its ...
Phys.org / Virtual cell model could accelerate protein-degrader therapy design
A team of Weill Cornell Medicine investigators has developed a computer model that will help scientists more efficiently develop protein-destroying therapies, a newer type of treatment that is particularly promising for cancer. ...
Phys.org / Egypt's deserts were once home to a diverse shark community
During the Late Cretaceous period, parts of Egypt were covered in water. A new study, published in the journal Cretaceous Research, describes new evidence that this tropical sea was home to a diverse community of sharks. ...
Phys.org / We discovered rare dinosaur tracks from the Coniacian age near Tumbler Ridge, British Columbia
Imagine the Western Plains of North America, from Texas to Alaska, submerged under a broad, shallow seaway. To the west lay the ancestral Rocky Mountains. To the east were low-lying plains traversed by large, sluggish rivers.
Phys.org / The hidden physics behind the shape of rose thorns
Roses are known for their thorns, the sharp structures that can sting and prickle the skin. Thorns, botanically known as prickles, are thought to discourage animals from feeding on plants and may also help climbing roses ...
Phys.org / Reworked tRNAs enable protein design with up to 34 amino acids
Scientists have been hard at work for more than 20 years to instruct biological systems, such as E. coli cells, to produce proteins they don't naturally produce. Success could mean faster, cheaper, more innovative solutions ...
Phys.org / Observing the vibrations of neighboring atoms with an atomic-scale double slit
Efficiently controlling heat generation has become a major challenge as the semiconductors used in smartphones, computers and similar devices have become higher-performing and more miniaturized. The way heat is transmitted ...
Phys.org / Utah mountain ranges may store a billion tons of hidden ice
Unlike conventional glaciers, rock glaciers appear as piles of rock that obscure large masses of unaccounted-for ice. Rock glaciers are common in the Wasatch and Uinta ranges, even appearing on the Colorado Plateau in the ...
Medical Xpress / More accurate risk assessment developed for Alzheimer's disease among nonwhite patients
Late-onset Alzheimer's disease (AD) is a progressive disorder characterized by cognitive decline and memory impairment, affecting an estimated 6.9 million people in the U.S. The clinical course of AD unfolds over many years, ...
