Scientists have found the strongest evidence yet that our brains can compensate for age-related deterioration by recruiting other areas to help with brain function and maintain cognitive performance.
Researchers studied in detail the strange protist Meteora sporadica, which swings its two lateral arms back and forth. The results of the study indicated that M. sporadica has a complex cytoskeleton that is closely related to Hemimastigophora, a group of organisms considered to be one of the deepest branches of eukaryotes.
Researchers have discovered peptide factors that function in the shoot and root systems to transport iron into the root nodules colonized by nitrogen-fixing bacteria. Moreover, these peptide factors regulate nitrogen homeostasis by maintaining a balance between nitrogen and iron concentrations in plants without rhizobial symbiosis.
Doctors do not perform as well diagnosing skin diseases when the patient has darker skin, according to a new study. The researchers found assistance from artificial intelligence could improve doctors' accuracy, but those improvements were greater in patients with lighter skin.
China's Chang'e-5, the first lunar sample return mission since the Soviet Union's Luna 24 in 1976, delivered 1.73 kilograms of regolith from the Oceanus Procellarum, a plane named for its vast size. The sample landed with CE-5 in late 2020 and included a new mineral, Changesite-(Y), as well as a perplexing combination of silica minerals. Researchers now compare CE-5's material composition to other lunar and Martian regolith samples and examine potential causes and origins for the lunar sample's unique makeup.
The Seattle fault zone is a network of shallow faults slicing through the lowlands of Puget Sound, threatening to create damaging earthquakes for the more than four million people who live there. A new origin story, proposed in a new study, could explain the fault system's earliest history and help scientists improve hazard modeling for the densely populated region.
Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests.
Influenza A viruses with induced resistance to a new candidate antiviral drug were found to be impaired in cell culture and weakened in animals, according to a new study.
Most women agree that menopause has its advantages and disadvantages. Some relish the end of menstruation and concerns about unplanned pregnancies, while others dread the possibililty of hot flashes, moodiness, and other unpleasant symptoms. What some women consider a brief and barely noticeable phase in their lives can evolve into lasting changes and discomfort for others. Now, a new paradigm around the biological processes of menopause is capturing the attention of a small group of scientists around the country. The primary question: can menopause be delayed in healthy women, allowing them to extend their child-bearing years -- and perhaps even forestall some of the health risks and uncomfortable symptoms linked to plummeting estrogen levels?
Scientists can now predict which single-letter changes to the DNA within our genomes will alter genetic instructions and disrupt development, leading to changes such as the growth of extra digits and hearts. Such knowledge opens the door to predictions of which enhancer variants underlie disease in order to harness the full potential of our genomes for better human health.
