Researchers mapped distinct bone marrow niche populations and their differentiation paths for the bone marrow factory that starts from mesenchymal stromal cells and ends with three types of cells — fat cells (adipocytes), bone-making cells (osteoblasts) and cartilage-making cells (chondrocytes).

While artificial leaves hold promise as a way to take carbon dioxide — a potent greenhouse gas — out of the atmosphere, there is a “dark side to artificial leaves that has gone overlooked for more than a decade,” according to Meenesh Singh, assistant professor of chemical engineering in the University of Illinois at Chicago College of Engineering.

A newly developed technique that shows artery clogging fat-and-protein complexes in live fish gave investigators from Carnegie

The rise in temperature and precipitation levels in summer in northern Japan has negatively affected the growth of conifers and resulted in their gradual decline

More than one million plant and animal species worldwide are facing extinction, according to a recent United Nations report.

The discovery that an essential protein plays a protective role during cell division, could open the door to better targeted treatment of fast-growing cancer cells.

Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) investigating how to make desalination less expensive have recently hit on promising design rules for making so-called “thermally responsive” ionic liquids to separate water from salt.

New research, conducted in part at Texas State University, suggests that warming temperatures in the Arctic may be contributing to a rise in North American heat waves.The study highlights a statistical relationship between Arctic sea ice and extreme weather events in the United States. The research suggests that during warmer years in the Arctic when sea ice is low, heat waves are more frequent to the south across much of the eastern half of the U.S. due to North Atlantic ocean-atmosphere interactions involving jet stream currents in the Northern Hemisphere. The evidence suggests these factors allow specific weather patterns, including heat waves, to persist for longer periods than the historical norm.

Los Alamos National Laboratory scientists have developed a new quantum computing algorithm that offers a clearer understanding of the quantum-to-classical transition, which could help model systems on the cusp of quantum and classical worlds, such as biological proteins, and also resolve questions about how quantum mechanics applies to large-scale objects.

Researchers at the University of New Hampshire took a closer look at shale natural gas energy development (SGD) and how it is affecting the experiences of outdoor recreationists, like hikers and campers. They found a significant number of recreationists encountered SGD-related activities and a smaller number even changed their outdoor behaviors or experiences as a result of encountering SGD.

A study is the first to examine the relationship between parental mental illness like anxiety and depression in childhood and the risk of suicide and self-harm in adults who suffer from tinnitus, noise or ringing in the ears, and hyperacusis, extreme sensitivity to noise. Results show that among patients seeking help for these debilitating hearing disorders, poor mental health in their parents was associated with suicide and self-harm risk across the life span in addition to their own current depression level.

Researchers at Texas State University, collaborating with a team from the University of New Mexico, have discovered that fish can smell viruses, prompting fast antiviral immune responses.

Ketamine has gotten a bad rap as an opioid when there’s plenty of evidence suggesting it isn’t one, Johns Hopkins experts say. They believe this reputation may hamper patients from getting necessary treatment for the kinds of depression that don’t respond to typical antidepressants. In a new paper, the researchers clarify the mechanism behind ketamine’s mechanism of action in hopes of restoring the therapy’s standing among health care professionals and the public.
