A new evolutionary analysis suggests that modern blood and immune cells may preserve a 700-million-year legacy inherited from ancient single-celled ancestors. Long before humans, dinosaurs, or even fish existed, ancient single-celled organisms may have already carried the genetic blueprint for one of the body’s most important systems: blood. A new study from Kyoto University suggests [...]

A study of a few patients, to be presented this week, showed promise for a type of therapy that has already cured some blood cancers.

Tiny molecules in the blood can strongly predict short-term survival in older adults, according to new research. As people get older, it can be difficult to tell who is likely to remain healthy and who may face a higher risk of serious decline. New research suggests that clues to that risk may already be present [...]

Scientists have uncovered a hidden layer of genetic regulation that helps explain why individuals with the same blood type can differ so dramatically at the molecular level. A long-standing mystery in blood science has finally been solved, and the answer could make blood transfusions safer while shedding light on how our bodies fight disease. Researchers [...]

Long-term genetic tracking of patients with chronic blood cancers is revealing hidden patterns in how these diseases develop and progress. Following patients over time has revealed key genetic differences between blood cancers that remain stable and those that become more aggressive. The findings also show how DNA data could sharpen diagnoses, improve how patients are [...]

A known cell-death protein turns out to quietly reshape stem cell aging. As people grow older, the body’s ability to maintain healthy blood and a strong immune system gradually weakens. A major reason is the decline of hematopoietic stem cells (HSCs), which are responsible for producing all types of blood cells. Under normal conditions, HSCs [...]

ApoB testing outperforms traditional cholesterol measures in preventing heart attacks and strokes while remaining cost-effective. It more accurately identifies risk, leading to better treatment decisions. A common blood test used by millions of people in the U.S. each year to measure “bad” cholesterol may not be the most reliable tool for guiding treatment or preventing [...]

MethylScan is a low-cost blood test that detects cancers and organ diseases by analyzing DNA methylation, improving early diagnosis, and identifying disease origin. UCLA researchers have created a simple, low-cost blood test that may be able to detect multiple cancers, liver diseases, and organ abnormalities at the same time by analyzing DNA fragments circulating in [...]

Zatímco pro Doom nebo Quake existuje celý obrovský oceán různých fanouškovských projektů, nových levelů, módů a spoustu dalších zajímavých věcí, u některých jiných her je nový obsah spíše vzácnější záležitostí.

Ultramarathons might push red blood cells past their limits—accelerating their aging in the process. Running extreme distances may take a toll on the body at the cellular level. A study published today (February 18) in the American Society of Hematology’s journal Blood Red Cells & Iron reports that ultra-endurance events can damage red blood cells [...]

A toxic link between a brain protein and a blood protein may be the hidden spark that starts Alzheimer’s. Researchers have long recognized that Alzheimer’s disease is marked by abnormal plaques and tangled proteins in the brain. More recently, attention has turned to the brain’s blood vessels and how problems in the vascular system may [...]

A new CRISPR-powered light sensor can detect the faintest whispers of cancer in a single drop of blood. Scientists have created an advanced light-based sensor capable of identifying extremely small amounts of cancer biomarkers in blood. The technology could eventually allow doctors to detect early warning signs of cancer and other diseases through a routine [...]
