Medical Xpress / Blood proteins shift during Alzheimer's treatment and may help monitor the effects of the medication
Patients with early symptoms of Alzheimer's disease may be prescribed anti-amyloid therapy, which can help clear the sticky clumps of amyloid protein in the brain that characterize Alzheimer's. While these treatments cannot ...
Phys.org / Alaska's orange rivers are more metallic than acid mine drainage
The bright orange plumes of water scientists first noticed billowing across a river in Alaska's Brooks Range in 2018 were even more acidic and metallic than water leached from metal mines, despite their pristine surroundings. ...
Medical Xpress / One gene helps drive growth in two childhood brain tumor groups that lack targeted therapies
Targeting KDM2B or downstream protein complexes it recruits may exploit a vulnerability in high-risk medulloblastoma subgroups that currently lack targeted therapies, according to a study led by St. Jude Children's Research ...
Medical Xpress / Older Americans are taking more medications, with 1 in 5 at risk for a major drug interaction
Older Americans are increasingly taking multiple prescription medications and dietary supplements. Although the prevalence of potentially major drug-drug interactions has declined slightly, more than 1 in 5 older adults are ...
Phys.org / Bennu asteroid samples point to a surprising origin involving Jupiter
The asteroid Bennu orbits the sun once every 1.2 years and approaches Earth every six years, passing within around 300,000 kilometers. NASA took advantage of this to collect material from the celestial body. In a spectacular ...
Medical Xpress / Three heart cell receptors share unexpected signal that drives scar formation
Researchers at the Stanford Cardiovascular Institute have characterized an unexpected signaling pathway that helps drive cardiac fibrosis, the buildup of scar tissue that makes the heart stiffer and less able to pump normally. ...
Phys.org / 'Jumping genes' helped ants in their evolutionary triumph after the extinction of the dinosaurs
About 66 million years ago, the asteroid that ended the age of the dinosaurs paved the way for a spectacular expansion of new animal species. During this period, ants rose to ecological dominance. Today, they form the largest ...
Medical Xpress / When the eyes play tricks, the brain builds consensus
Have you ever seen something that doesn't quite add up? Maybe a shape in the dark resembles a face, or an orange momentarily looks like an apple. Scientists now have a new idea about how different brain regions may work together ...
Phys.org / September's ozone hole was the biggest in 20 years
The area covered by the Antarctic ozone hole peaked at more than 27 million square kilometers (10.4 million square miles) in September, the second-largest area ever observed for this time of year.
Dialog / Critically endangered species in the heart of Africa: Investigating Hooded Vultures in Chad
Slaughterhouses are places most people never want to go, and might seem like unlikely places to search for rare or endangered species. In West Africa, however, they are among the last places one can find a critically endangered ...
Phys.org / Bay Area wastewater plants could nearly halve nitrogen cleanup costs by coordinating upgrades
Treating polluted water flowing into San Francisco Bay to meet regulatory requirements is going to cost ratepayers money. Exactly how much depends, in large part, on whether the region's wastewater treatment plant operators ...
Phys.org / The far side of the moon provides clues to a past magnetic field
Unlike Earth, the moon no longer has a core-generated magnetic field. On our planet, the movement of liquid iron in the outer core generates a global magnetic field. This so-called geodynamo works on a similar principle to ...
