Under the right economic conditions, a growing demand for forest products that accompanies development may lead to an increase – not a decline – in forest cover, according to a new study by researchers at Brown University and Harvard University. Policies that focus on reducing paper demand may not necessarily increase forestation.

The study examined the connection between the economy and forest cover in India, a country with a relatively closed economy that experienced an apparent increase

Computer security researchers suggest ways to thwart new form of cybercrime

Most experts on computer crime focus on attacks against Web servers, bank account tampering and other mischief confined to the digital world. But by using little more than a Web search engine and some simple software, a computer-savvy criminal or terrorist could easily leap beyond the boundaries of cyberspace to wreak havoc in the physical world, a team of Internet security researchers has concluded.

Results from Model-based functional genomics research provides new insight on the pathogenetic mechanism which causes diseases such as ALS

Ingenium Pharmaceuticals AG and a coalition of international research organizations announced today the publication in Science of research describing a fundamental discovery about the genetic and molecular basis for Motor Neuron Disease (MND), which includes Amyotrophic Lateral Sclerosis (ALS). The research explains a key pathogenetic mechanism of

In the fall of 1952, Stanley Miller, now a chemistry professor emeritus at the University of California, San Diego (UCSD), began simulating primitive earthly conditions in an experiment that produced the basic building blocks of life. When he published the results in Science on May 15 the following year, he kick-started research on the origin of life and transformed modern thinking on a dormant area of science.

Solving a longstanding scientific puzzle, researchers at the University of Illinois at Chicago have not only discovered how the body’s first line of defense against dangerous microbes inadvertently helps HIV rapidly infect the human immune system.

They’ve filmed the process as well.

In a remarkable series of movies created with images from time-lapse microscopy, UIC microbiologists Thomas Hope and David McDonald have documented how HIV enters human T cells, where it multip

Researchers at the University of Pennsylvania have created the first mammalian gametes grown in vitro directly from embryonic stem cells. The work, in which mouse stem cells placed in Petri dishes — without any special growth or transcription factors — grew into oocytes and then into embryos, will be reported this week on the web site of the journal Science.

The results demonstrate that even outside the body embryonic stem cells remain totipotent, or capable of generating any of the body&
