Researchers have developed an innovative technique to rejuvenate aged oocytes, or immature egg cells, to boost their quality, paving the way for improved outcomes for in-vitro fertilization. This groundbreaking approach involves constructing hybrid ovarian follicles by transplanting aged oocytes into a young follicular environment to partially restore their reproductive potential.

Researchers have found evidence that low oxygen levels in tumors could actually enhance some of the body's immune responses against cancer, in contrast with the general paradigm that hypoxia exclusively helps cancer progression. Their findings identified a macrophage subpopulation displaying more potent immune responses under low oxygen concentrations in tumors. Read more ›

A research team has discovered a mechanism in which blood stem cells respond to acute, severe anemia, through lipoprotein metabolism modification. It has been known how immediate erythroid precursors respond under acute anemic conditions, however, whether and how more immature stem cells react remained unknown. The outcome of this research is expected to contribute to the development of novel therapies for treating severe anemia patients who do not respond to... Read more ›

A new way of making ammonia by harnessing the unique power of liquid metal could lead to significant cuts in carbon emissions caused by production of the widely-used chemical. Ammonia is used in fertilizer to grow much of our food, but also plays a role in clean energy as a carrier to safely transport hydrogen. Read more ›

Rising temperatures are thought to reduce the number of ice crystals in clouds, leading to the formation of liquid-dominated clouds. However, a new study has found that Arctic warming is causing an increase in the emission of natural aerosols from snow/ice-free barren and vegetated areas in the Arctic. These aerosols can encourage ice crystal formation in mixed-phase clouds, potentially affecting cloud composition and the Arctic climate. Read more ›

The superior colliculus is a midbrain region that is traditionally thought to help animals orient themselves toward important locations in space, like directing their eyes and head toward a bright flash of light. New research shows that this part of the brain also plays a role in complex cognitive tasks like visual categorization and decision making. Read more ›

A drug approved for treating the blood cancer multiple myeloma may offer a safe and effective way to reduce the risk of severe nosebleeds from a rare but devastating bleeding disorder. Hereditary hemorrhagic telangiectasia (HHT), the world's second-most-common inherited bleeding disorder, affects approximately 1-in-5,000 people and can have life-threatening complications, but there are currently no U.S. FDA-approved drugs to treat HHT.

People whose diet more closely resembles the MIND diet may have a lower risk of cognitive impairment, according to a new study. Results were similar for Black and white participants. These results do not prove that the MIND diet prevents cognitive impairment, they only show an association. Read more ›

Some of the most dramatic climatic events in our planet's history are 'Snowball Earth' events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles thick. New research provides a more complete picture for how the last Snowball Earth event ended, and suggests why it preceded a dramatic expansion of life on Earth, including the emergence of the first...

A set of knee exoskeletons, built with commercially available knee braces and drone motors, has been shown to help counteract fatigue in lifting and carrying tasks. They helped users maintain better lifting posture even when tired, a key factor in defending against on-the-job injuries, the researchers say. Read more ›

Scientists at MPI-IS have developed electrically driven robotic components, called HEXEL modules, which can snap together into high-speed reconfigurable robots. Magnets embedded along the outside of the modules allow them to electrically and mechanically connect to other modules, forming robots with diverse shapes and capabilities. HEXEL modules are a promising technology for use in resource-limited environments, such as on space or rescue missions, and can be used to construct versatile... Read more ›
