Researchers Map Out Networks That Determine Cell Fate
A two-step process appears to regulate cell fate decisions for many types of developing cells. For some differentiating stem cells, the first step leads not to a final decision but to a new choice. In response to the initial chemical signal, these cells take on the genetic signatures of two different cell types. It often requires a second signal for them to commit to a single cellular identity. Quantum Information Research Could Transform The Power Of Computing
Although presently a very young field, Quantum Information Science and Technology (QIST) could well have a vital role to play in future information and communication technologies. Quantum computing and communication techniques have the potential to transform the way we think about computing power. No More Hiroshima Earrings
This article from 1999 describes how "an American museum has stopped selling earrings in the shape of the nuclear bombs dropped on Hiroshima and Nagasaki in 1945."Includes an image of the earrings, which are miniature replicas of "Little Boy"and "Fat Man,"the atomic bombs dropped in August 1945 on those cities in Japan.

When people living in many parts of the world move their clocks forward one hour in the spring in observance of daylight savings time, their bodies'internal, daily rhythms don't adjust with them, reports a new study. Depressed Patients Experience Excessive Inflammation During Stressful
Individuals with major depression have an exaggerated inflammatory response to psychological stress compared to those who do not suffer from depression, according to a study by researchers at Emory University School of Medicine. Because an overactive inflammatory response may contribute to a number of medical disorders as well as to depression, the findings suggest that increased inflammatory responses to stress in depressed patients may be a link between depression and other diseases, including heart disease, as well as contributing to depression itself. Blindness From Smoking Terrifies Teens, But Few Realize The Two Are Li
Teenagers fear blindness more than lung cancer or stroke, but nine out of 10 don't know that smoking can rob them of their sight in later life, reveals research published ahead of print in the British Journal of Ophthalmology. The findings are based on the responses of 260 clubbers aged between 16 and 18, collected at four UK venues in Bournemouth, Winchester, Manchester and Southampton. Patients Over Age 60 Do Well After Liver Transplantation
Patients who undergo liver transplantation at age 60 or above have one-year and five-year survival rates similar to those of younger patients and they experience fewer episodes of rejection. Older patients have long been considered high-risk recipients, because they may have other conditions and diseases alongside their liver problem, and because they have increased mortality risk overall. However, older patients have softer immune systems, which might reject transplants less often, leading to better outcomes. Early Social Experiences Can Influence Adult Behavior In Romantic Rela
The way in which individuals think, feel, and behave in their adult romantic relationships is governed not only by factors in their immediate surroundings, but is also a direct result of their past relationships and personal attachment extending all the way back to childhood. Moss Genes Provided Fuse For Plant Life Explosion
Scientists have identified the genes that control the development of root hairs on plants. These genes are also found in moss, a finding that changes our understanding of how the plants we see today evolved over 400 million years ago. Plants use roots to anchor themselves, and to absorb nutrients. Root hairs are single cells that grow from the roots and greatly increase the root's surface area. The researchers identified a pair of genes that are required for root hairs to grow. When these genes were turned off, plants produced hairless roots. SMS Your ECG To ER: Portable Heart Monitor Sends Emergency Alerts And
A Bluetooth heart monitor could text your local hospital if you are about to have a heart attack, according to research published today in Inderscience's International Journal of Electronic Healthcare. The device measures electrical signals from the heart, analyses them to produce an electrocardiogram and sends an alert together with the ECG by cell phone text message.
