Israelis find reeaaaally old fireplace hearth

It's generally reckoned that early man "discovered" fire somewhere around a million years ago, but it's still unclear when he began to control and...

New Stem Cells Go Back Further

One of the obstacles to employing human embryonic stem cells for medical use lies in their very promise: They are born to rapidly differentiate...

Sending multiple sclerosis up in smoke

Multiple sclerosis is an inflammatory disease in which the immune system attacks the nervous system. The result can be a wide range of debilitating...

Perfecting digital imaging

Computer graphics and digital video lag behind reality; despite advances, the best software and video cameras still cannot seem to get computer-generated images and...

Gas rich galaxies confirm prediction of modified gravity theory

COLLEGE PARK, Md. -- Recent data for gas rich galaxies precisely match predictions of a modified theory of gravity know as MOND according to a new analysis by University of Maryland Astronomy Professor Stacy McGaugh. This -- the latest of severa...

Hope for stroke victims

Much of the devastation of stroke and head trauma is due to damage caused the overproduction of a substance in the brain called glutamate. Preventing this damage has been impossible, until now, as many drugs don't cross the so-called blood-brain bar...

New technology gives on-site assessments in archaeology

DURHAM, N.C. -- The ability to tell the difference between crystals that formed naturally and those formed by human activity can be important to archaeologists in the field. This can be a crucial bit of information in determining the ancient a...

Physical environment influences stem cell development

Jerusalem -- September 6, 2010 -- A researcher at the Hebrew University of Jerusalem, together with Israeli and foreign collaborators, has revealed how physical qualities -- and not only chemical ones -- may have an influence in determining...

Gene Responsible For Anemia (Type CDA-1) Discovered

A combined effort between Israeli scientists has led to the discovery of a gene responsible for a type of anemia primarily found in a number of Bedouin families, called congenital dyserythropoietic anemia-1 (CDA-1). The findings, published the December issue of The American Journal for Human Genetics, could lead to effective detection and eventually treatment of the disease. In addition, understanding the role of this gene?s protein product in the body could provide important clues to other types of anemia, as well as to the general mechanisms of blood cell formation.

Transplanted tissue could offer a solution to kidney donor shortage

Instead of searching for a kidney donor, a new study suggests, one might be able to grow a new kidney. A team headed by Prof. Yair Reisner of the Weizmann Institute of Science has induced human stem cell tissue to grow into functional kidneys, and have accomplished the same with porcine stem cell tissue. Published in Nature Medicine, the method could lead to a promising solution to the severe shortage of kidney donors.
