Phys.org / Cryoelectron tomography reveals paracrystalline architecture of proteasome storage granules
Cells organize their molecules into distinct functional areas. While textbooks usually refer to membrane-bound organelles such as mitochondria and cell nuclei, recent studies have also revealed organelles without membranes. ...
Medical Xpress / Sleeping without pillows may lower harmful high internal eye pressure in people with glaucoma
Sleeping without pillows may help lower high internal eye pressure, the build-up of which causes optic nerve damage and glaucoma—the leading cause of irreversible blindness worldwide—in people with the condition, suggests ...
Phys.org / Plant mothers send molecular 'text messages' to pollen
Small RNAs are short RNA molecules that help determine which genes in a cell are switched on or off. Until now, it was assumed that the small RNAs necessary for pollen development originate in the pollen itself and in the ...
Phys.org / Residents from strongly blue or red counties favor like-minded destinations for everyday travel, analysis finds
A new analysis of 471 U.S. counties has found that, for everyday travel, people from counties with particularly strong political leanings—whether liberal or conservative—are more likely to visit like-minded destinations. ...
Medical Xpress / Why U.S. middle-aged adults report more loneliness and poorer health than peers abroad
Americans born in the 1960s and early 1970s report higher loneliness and depressive symptoms and show poorer memory and physical strength than earlier generations. Such declines are largely absent in peer countries, particularly ...
Medical Xpress / How genes influence the microbes in our mouths to shape dental health
No matter how much they brush their teeth, some people still get more cavities than others, in part because of differences in genetics and the make-up of the microbes in their mouths. A new study has found human genetic factors ...
Phys.org / Streaks on Mercury show that it is not a 'dead planet'
Although Mercury was geologically active in its early days, today its surface appears almost completely static. This is why it is often perceived as a dead and dry planet. A new study led by Dr. Valentin Bickel from the Center ...
Phys.org / Capturing the moment of organelle handoff inside living cells
For the first time, researchers have directly visualized how newly formed cellular organelles leave the endoplasmic reticulum (ER) and transition onto microtubule tracks inside living cells. This new finding reveals that ...
Medical Xpress / Most doctor-made YouTube health videos lack strong proof, study finds
Many health videos on YouTube, even those made by doctors, may not be giving viewers reliable medical information, a new study suggests.
Phys.org / Sea levels are rising—but in Greenland, they will fall
Even as global warming causes sea levels to rise worldwide, sea levels around Greenland will likely drop, according to a new paper published in Nature Communications. "The Greenland coastline is going to experience quite ...
Medical Xpress / Continued exposure to certain heavy metals linked to ADHD in childhood
Impulsivity, hyperactivity, and difficulty concentrating are some of the symptoms associated with attention deficit hyperactivity disorder. It is estimated that 6% of schoolchildren in Catalonia suffer to a greater or lesser ...
Phys.org / Global health impacts of plastics systems set to double by 2040
The adverse health impacts associated with emissions across the full life cycle of plastics could double by 2040 unless immediate action is taken, new research suggests. The study identified health harms at every stage of ...
