Plans to be discussed at the forthcoming UN climate conference in Copenhagen to cut deforestation in developing countries could save some species from extinction but inadvertently increase the risk to others, scientists believe.
A team of eleven of the world`s top tropical forest scientists, coordinated by the University of Leeds, warn that while cutting clearance of [...]

A team of scientists at Cold Spring Harbor Laboratory (CSHL) reports on Thursday their success in solving the molecular structure of a key portion of a cellular receptor implicated in Alzheimer`s, Parkinson`s, and other serious illnesses.
Assistant Professor Hiro Furukawa, Ph.D., and colleagues at CSHL, in cooperation with the National Synchrotron Light Source at Brookhaven National [...]

Researchers have transplanted genetically modified hematopoietic stem cells into mice so that their developing red blood cells produce a critical lysosomal enzyme -preventing or reducing organ and central nervous system damage from the often-fatal genetic disorder Hurler`s syndrome.
The research team from Cincinnati Children`s Hospital Medical Center reports its preclinical laboratory results this week in the [...]

Embryonic development is like a well-organised building project, with the embryo`s DNA serving as the blueprint from which all construction details are derived. Cells carry out different functions according to a developmental plan, by expressing, i.e. turning on, different combinations of genes. These patterns of gene expression are controlled by transcription factors: molecules which bind [...]

Researchers at Karolinska Institutet have discovered a mechanism that controls the brain`s ability to create lasting memories. In experiments on genetically manipulated mice, they were able to switch on and off the animals` ability to form lasting memories by adding a substance to their drinking water. The findings, which are published in the scientific journal [...]

The alcohol industry`s sponsorship of sport should be banned and replaced with a dedicated alcohol tax modelled on those employed by some countries for tobacco, say scientists.
Writing in the latest issue of the international journal Addiction, the authors have called on governments to outlaw the practice, citing their highly publicised 2008 study that showed alcohol-industry [...]

If you forget your password when logging into an e-mail or online shopping Web site, the site will likely ask you a security question: What is your mother`s maiden name? Where were you born?
The trouble is that such questions are not very secure. More people than you may think will know your answers. And if [...]

What do you get when you cross a mouse with poor hearing and a mouse with even worse hearing? Ironically, a new strain of mice with "golden ears" — mice that have outstanding hearing as they age.
The work by one of the world`s foremost groups in age-related hearing loss, or presbycusis, marks the first time [...]

The same genes that are chemically altered during normal cell differentiation, as well as when normal cells become cancer cells, are also changed in stem cells that scientists derive from adult cells, according to new research from Johns Hopkins and Harvard.
Although genetically identical to the mature body cells from which they are derived, induced pluripotent [...]

A group of drunken fruit flies have helped researchers from North Carolina State and Boston universities identify entire networks of genes — also present in humans — that play a key role in alcohol drinking behavior.
This discovery, published in the October 2009 print issue of the journal Genetics, provides a crucial explanation of why some [...]
