A new study shows that this ability is probably human unique. Even the closest relatives of humans, such as bonobos, do not learn order in the same way. Wed, 06 Sep 2023 14:34:42 EDT //www.koonmotors.com/releases/2023/09/230906143442.htm //www.koonmotors.com/releases/2023/09/230906143429.htm Not only does a lack of sleep make you feel awful, research has shown it impairs the brain. What's more, sleep loss over long periods can even increase risk for Alzheimer's and other neurological diseases. Researchers want to understand how sleep deprivation causes this harm. In a new study, a team working with mice has identified a protective protein whose level declines with sleep deprivation, leading to neuronal death.

Researchers discovered that immune cells do not just passively follow the chemical cues in their environment. Quite the contrary, they can also shape these cues and navigate in complex environments in a self-organized manner. Wed, 06 Sep 2023 11:24:40 EDT //www.koonmotors.com/releases/2023/09/230906112440.htm //www.koonmotors.com/releases/2023/09/230906112437.htm A team of researchers has revealed that the Dumpy protein, a component of extracellular matrices -- or ECM -- is the key factor in regulating the stereotypic origami-like folding of wing-cell sheets. Their findings that wing cells never divide during folding nor do they exhibit spatially distinct behaviors suggest how external cues can create consistent 3D tissue structures.

These parts contain additives that contribute to their flexibility and durability, but these potentially harmful compounds can leak into drinking water, according to a small-scale study. The authors report that the released compounds, which are typically linked to tire pollution, also transformed into other unwanted byproducts.

Wed, 06 Sep 2023 11:24:12 EDT //www.koonmotors.com/releases/2023/09/230906112412.htm //www.koonmotors.com/releases/2023/09/230906112407.htm The liver produces bile, which the intestine uses for digestion. For the transport of bile, the liver relies on a network of microscopic tubings, known as bile canaliculi, formed by liver cells called hepatocytes. When the outflow of bile to the intestine is blocked, it collects in the liver and can lead to serious liver disease. Researchers found that high pressure in the bile canaliculi alters the structure of the liver tissue. They found that elevated pressure leads to the obviation of apical bulkheads, structures known to reinforce the canaliculi. Subsequently, bile canaliculi enlarge into liver cell rosettes that are observed in many liver diseases. This study identifies pressure to be a potential common cause of various liver diseases with biliary obstruction and thus contributes to a better understanding of liver diseases.

Treatment options for people experiencing irritating or severe menopause symptoms are often under researched, and some have questionable efficacy, or cause harmful side effects. Menopause experts now summarize what we know about menopause, call for more research into the timeline and treatment of menopause, and encourage individualized, holistic treatment that addresses both menopausal symptoms and other systemic changes happening in the body.

That's according to a recent study that found social factors -- such as low population density, high housing vacancy, disability and race -- can have a stronger influence than median household income on whether a community's municipal water supply is more likely to have health-based water-quality violations.

The study authors highlight that neighborhoods with predominantly Black, Hispanic and Latinx residents would benefit the most -- potentially reducing disproportionate pollution and health burdens in historically marginalized areas.

It also found that body appreciation is higher in those who are single and those living in rural areas. Amongst the 65 nations, Australia followed by India and then the United Kingdom recorded the lowest scores, while Malta scored highest.
