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 / Roman telescope aims to directly image exoplanets 1,000 times fainter than current limits
The Roman Space Telescope is designed to directly image exoplanets using complex optomechanical systems developed by the Max Planck Institute for Astronomy
Phys.org / Geomimicry offers a new framework for engineering sustainable materials
When engineers look to nature for inspiration, they often turn to living systems. The flight of birds has influenced aircraft design, gecko feet inspired new adhesives and lotus leaves led to the development of self-cleaning ...
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. ...
Medical Xpress / Almost a third of women in their 20s have never been screened for cervical cancer
The percentage of women in their 20s who have never been screened for cervical cancer has been increasing at a disturbing rate over the past 20 years—to the point that almost a third of women ages 21 to 29 have never been ...
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 / 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 ...
Medical Xpress / Intermittent fasting reveals gut-brain pathway that may reduce chronic pain
Chronic pain, pain that persists or returns for more than three months, can affect people's emotional well-being and is often accompanied by difficulty concentrating or remembering things. While they can be effective for ...
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 / 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 ...
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 ...
