Tiny algae in Earth's oceans and lakes take in sunlight and carbon dioxide and turn them into sugars that sustain the rest of the aquatic food web, gobbling up about as much carbon as all the world's trees and plants combined.
New research shows a crucial piece has been missing from the conventional explanation for what happens between this first "fixing" of CO2 into phytoplankton and its eventual release to the atmosphere or descent to depths where it no longer contributes to global warming. The missing piece? Fungus.
Though it might seem inanimate, the soil under our feet is very much alive. It's filled with countless microorganisms actively breaking down organic matter, like fallen leaves and plants, and performing a host of other functions that maintain the natural balance of carbon and nutrients stored in the ground beneath us.
Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal conductors only if temperatures are high enough; at low temperatures, they act like insulators and do not do a good job of carrying electricity. In other words, these unusual materials go from acting like a chunk of gold to acting like a piece of wood as temperatures are lowered.
A new drug reduced tumor size in patients who have lung cancer patients with a specific, disease-causing change in the gene KRAS, a study found.
The results of the CODEBREAK 100 phase 2 clinical trial were presented June 4, 2021, at the American Society of Clinical Oncology (ASCO) annual meeting and published simultaneously in the New England Journal of Medicine. The efficacy and safety of the drug sotorasib, developed by Amgen Inc., was tested in patients with non-small-cell lung cancer (NSCLC) harboring a specific change, or mutation, in the DNA code for KRAS.

Bottom Line: The majority of surveyed Americans had an inadequate understanding of palliative care, and frequency of health care utilization was one determinant of knowledge.

Dogs may have earned the title "man's best friend" because of how good they are at interacting with people. Those social skills may be present shortly after birth rather than learned, a new study by University of Arizona researchers suggests.
Published today in the journal Current Biology, the study also finds that genetics may help explain why some dogs perform better than others on social tasks such as following pointing gestures.
WASHINGTON (June 3, 2021) - Nearly three-quarters of breast cancer patients (73%) report using at least one type of complementary medicine after cancer diagnosis, while oncologists believe that less than half (43%) of patients are using these approaches during cancer care. These and other findings from a national survey of oncologists and breast cancer patients were released in conjunction with the 2021 ASCO Annual Meeting. The study found that doctors report discussing integrative health with only about half of patients, leading patients to seek information outside the clinic.
Astronomers studying the fast-moving jet of material ejected by a still-forming, massive young star found a major difference between that jet and those ejected by less-massive young stars. The scientists made the discovery by using the U.S. National Science Foundation's Karl G. Jansky Very Large Array (VLA) to make the most detailed image yet of the inner region of such a jet coming from a massive young star.
(SACRAMENTO, Calif.) - An international team of researchers, led by UC Davis Health, has developed a new therapeutic approach to treating psoriatic arthritis, a chronic inflammatory disease affecting the joints.
Using a novel chemical blocker targeting chemokine proteins, the researchers were able to significantly reduce skin and joint inflammation in a mouse model with psoriasis and psoriatic arthritis.
A recent study by a team of researchers led by Dr Vinod Kumar Saranathan from the Division of Science at Yale-NUS College has discovered a complex, three-dimensional crystal called the single gyroid within feathers of the blue-winged leafbird. Dr Saranathan and his team's breakthrough came from their investigation of the feather colours of leafbirds, an enigmatic group of perching birds endemic to South and Southeast Asia (including Singapore), one species of which has evolved the unique crystals in its plumage.
BUFFALO, N.Y. - College students who engaged in four or more high-impact practices such as study abroad or internships have a 70% chance of either enrolling in graduate school or finding a full-time job after graduating with a bachelor's degree, finds a new University at Buffalo study.
Lithium is a vital element in the batteries that power electric vehicles, but soaring lithium demand is expected to exhaust land-based reserves by 2080. KAUST researchers have now developed an economically viable system that can extract high-purity lithium from seawater.
Regular strength and impact-type training may decrease or even prevent age-related bone deterioration in men, new research at the University of Jyväskylä, Finland, shows. The tibial bone properties of middle-aged and older male sprint athletes were followed over 10 years. The study presents novel findings on maintaining the adaptability of the aging skeleton and on the importance of regular intensive training for maintaining bone health.
