Phys.org / How actin wavefronts rescue T cell receptors from endocytosis
Every time our body encounters a new disease-causing agent, a crucial defense system called adaptive immunity comes into play. T cells, the top agents in this system, survey the internal environment of infected cells and ...
Phys.org / Plant diversity shapes chemical communication in ecosystems
Researchers at the Max Planck Institute for Chemical Ecology and the University of Kiel have provided experimental evidence showing that reducing plant species diversity alters plant chemical signals across whole communities ...
Phys.org / Tiny titans of recovery: Fossil burrows reveal resilient micro-ecosystem after global mass extinction
An international team of scientists from South Africa, Canada, France and the UK has uncovered fossil evidence of a tiny ecosystem that helped kick-start the recovery of Earth's oceans after a global mass extinction.
Phys.org / New map reveals a rugged world beneath the Antarctic ice sheet
Scientists have discovered there is more to Antarctica than meets the eye. A new map of the landscape beneath the frozen continent's ice sheet has revealed a previously hidden world of mountains, deep canyons and rugged hills ...
Phys.org / Sideways discovery rewrites the rules of antigen presentation
A new discovery about how cells communicate with each other in the body's immune system has revealed deeper insights for an international team of scientists into fundamental immune system function.
Medical Xpress / Oral drug can safely lower triglycerides and other blood lipids, clinical trial finds
When eating, the body converts extra calories, especially from carbs, sugar, fats, and alcohol, into triglycerides. Triglycerides are a form of fat or lipid, which the body stores away into its fat cells as an energy fuel ...
Phys.org / When tropical oceans were oxygen oases
Research reveals when and why ancient tropical seas transitioned from oxygen oases to marine dead zones, providing clues to the long-term evolution of oceanic environments.
Phys.org / Exploring mutations that spontaneously switch on a key brain cell receptor
Many people are familiar with histamine, a biological molecule that serves as a key driver of allergic reactions and other immune responses. However, histamine is also a major neurotransmitter in the mammalian brain, regulating ...
Medical Xpress / Ion channel offers promising avenue for new Parkinson's drugs
Lysosomes are the recycling centers of human cells. Larger molecules are broken down inside the membrane-enclosed vesicles. Malfunctions can lead to neurodegenerative diseases such as Parkinson's.
Medical Xpress / 1 in 5 people say losing their pet was worse than losing a person
For one in five people, losing a pet has been more distressing than losing a human loved one. New research has revealed that 21% of those who experienced both types of bereavement found their pet's death harder to bear.
Medical Xpress / Decline in U.S. nursing home capacity since COVID-19: Rural areas hit hardest
Though the U.S. population is aging, nursing home capacity has declined nationwide since the COVID-19 pandemic began. According to a study published in JAMA Internal Medicine this week, one quarter of U.S. counties experienced ...
Phys.org / Biomass-derived furans offer sustainable alternative to petroleum in chemical production
A research project conducted by the Max-Planck-Institut für Kohlenforschung shows how biomass can be used as a raw material for chemical products instead of petroleum. The scientists have published their findings in the ...
