New data throws more support behind the theory that neutrinos are the reason the universe is dominated by matter.
The current laws of physics do not explain why matter persists over antimatter - why the universe is made of 'stuff'. Scientists believe equal amounts of matter and antimatter were created at the beginning of the universe, but this would mean they should have wiped each other out, annihilating the universe as it began.
Two internationally renowned stem cell experts have found an abundance of abnormal stem cells in the lungs of patients who suffer from Chronic Obstructive Pulmonary Disease (COPD), a leading cause of death worldwide. Frank McKeon, professor of biology and biochemistry and director of the Stem Cell Center, and Wa Xian, research associate professor at the center, used single cell cloning of lung stem cells to make their discovery. Now they are targeting the cells for new therapeutics.
APRIL 15, 2020, NEW YORK-- A Ludwig Cancer Research study has discovered a novel means by which bacterial colonies in the small intestine support the generation of regulatory T cells--immune cells that suppress autoimmune reactions and inflammation. The study, led by Ludwig MSK Director Alexander Rudensky and published in Nature, demonstrates that a microbial metabolite--the organic acid isoDCA--boosts the local generation of the immunosuppressive immune cells in the colon.
Children have an insatiable appetite to understand why things are the way they are, leading to their apt description as "little scientists". While researchers have been aware of children's interest in causal information, they didn't know whether it influenced children's preferences during real-world activities, such as reading.
CHAMPAIGN, Ill. -- Biological structures sometimes have unique features that engineers would like to copy. For example, many types of insect wings shed water, kill microbes, reflect light in unusual ways and are self-cleaning. While researchers have dissected the physical characteristics that likely contribute to such traits, a new study reveals that the chemical compounds that coat cicada wings also contribute to their ability to repel water and kill microbes.
The scientists report their findings in the journal Advanced Materials Interfaces.
Immunotherapy, which unleashes the power of the body's own immune system to find and destroy cancer cells, has shown promise in treating several types of cancer.
But the disease is notorious for cloaking itself from the immune system, and tumors that are not inflamed and do not elicit a response from the immune system -- so-called cold tumors -- do not respond to immunotherapies.
ANN ARBOR--Active older veterans fall more often than their more sedentary peers who never served in the armed forces, but they're less likely to injure themselves when they do, says a University of Michigan researcher.
A new study by Geoffrey Hoffman, U-M assistant professor of nursing, compared risks of noninjury falls and fall-related injuries in veterans and nonveteran populations, including whether risks differed according to physical activity and age. Historically, veterans are more physically active than nonveterans.

Top biomedical engineering researcher develops synthetic scaffolds for tendon and ligament regeneration
Previous synthetic tendon grafts have led to poor outcomes and implant rejection
Australia has one of the highest rates of anterior cruciate ligament (ACL) injuries in the world - and up to 25 percent of surgeries require revision
Australia's love of sport means it has one of the highest rates of knee anterior cruciate ligament (ACL) injury and reconstruction in the world.
Since the first discovery of photocatalytic water splitting on a TiO2 electrode under ultraviolet (UV) light, TiO2 materials have been widely investigated over the past few decades due to their unique properties such as nontoxicity, abundance, easy availability, and stability. For the moment, TiO2 materials present great potentials in the applications from the conventional areas (e.g., pigment, cosmetic, and toothpaste) to the latest developed areas including catalysis, energy storage and conversion, biomedicine, environmental remediation and so on.
As instances of antibiotic resistance increase in the medical field, scientists are reexamining natural materials for their potential use in medicine. Honey has been used for thousands of years, from the time of Pharaohs for their effectiveness in treating wounds and burns.
New York, NY--April 13, 2020--Photosynthesis on Earth is regulated by plant phenology--how plant life cycles interact with the climate--and environmental conditions, both of which changed substantially in recent decades. Unlike early-season photosynthesis which is mostly driven by warming temperatures or the onset of the wet season, late-season photosynthesis can be limited by several factors, such as plant life cycle and radiation, and its underlying mechanisms are less understood.
Scientists at the University of Alberta have shown that the drug remdesivir is highly effective in stopping the replication mechanism of the coronavirus that causes COVID-19, according to new research published today in the Journal of Biological Chemistry.
UNIVERSITY PARK, Pa. -- Commercially prepared baby foods that purport to be loaded with dark green vegetables are sweetened with fruit puree and often don't contain a high percentage of dark green vegetable content, according to a team of researchers.
ABERDEEN PROVING GROUND, Md. -- Materials used for a Soldier's personal protection gear may be tough enough for vehicles too, according to a new Army study.
Findings, released April 10 in the journal Polymer, show that polymers filled with carbon nanotubes could potentially improve how unmanned vehicles dissipate energy.
DALLAS - April 13, 2020 - Cancer cells avoid an immune system attack after radiation by commandeering a cell signaling pathway that helps dying cells avoid triggering an immune response, a new study led by UTSW scientists suggests. The findings, published in a recent issue of Nature Immunology, could eventually lead to new ways to augment existing treatments to fight this disease.
