Further investigation into ...
Researchers at the University of Warwick discovered that strawberry extracts positively activate the Nrf2 protein, decreasing blood lipids and cholesterol levels. This activation reduces the risk of developing heart disease and diabetes by counteracting post-meal blood glucose and low-density lipoprotein.
The US Department of Energy supports the search for the Higgs particle through the Large Hadron Collider. Thousands of American scientists and graduate students contributed to this research.
A new clinical study by the National Heart, Lung, and Blood Institute found that eltrombopag improved blood cell production in 11 out of 25 participants with severe aplastic anemia. The drug was well-tolerated, with few side effects, and six patients showed significant improvements in all three types of blood cells.
A systematic analysis found that most developing countries have made limited progress towards halving childhood hunger by 2015. The study estimates that the global developing world has less than a 5% chance of meeting this target, with significant improvements seen in Asia and Latin America.
A study published in Nature found that a cloud of dust circling a young star disappeared within three years, contradicting the commonly accepted timescale for dust removal. This sudden disappearance suggests that planet formation may be much faster or more efficient than previously thought.
Scientists have discovered a 'constant cloud' of potent inflammatory molecules surrounding the cells responsible for diseases like thickening of the arteries and rheumatoid arthritis. Monocytes, a type of white blood cell, were found to be surrounded by this constant cloud, which was propelled through the cell wall by lysosomes.
The yak genome provides new insights into high-altitude adaptation, with distinct gene expansions related to sensory perception and energy metabolism. The study also identified genes that may play important roles in regulating body response to hypoxia and optimizing energy from poor foods.
Researchers used human parkour athletes to simulate orangutan movements and found that swaying is the most efficient way to cross trees. This finding helps explain why orangutans spend most of their lives in trees despite their large size and low-energy diet.
Researchers have identified the interfascicular matrix (IFM) as essential for tendon function, suggesting it may be critical in preventing tendon overuse injuries. The finding has significant implications for understanding and treating tendon disorders that cost the UK economy billions of pounds annually.
A policy of single embryo transfer (SET) has been associated with a reduction in overall perinatal mortality for IVF and ICSI babies. SET has also been linked to lower risks of preterm birth and low birth weight, as well as sequelae such as prematurity and neonatal complications.
