Scientists have successfully filmed individual cells migrating within a functioning lymph node

The researchers hope to gain a deeper understanding of how our immune system functions from their detailed study of lymph node processes.

The prion appears to function as an evolutionary stepping stone

“This prion,” explains Lindquist, “has a capacity to hide and release genetic information throughout the entire genome that can contribute to new traits in a complex way.”

New method for building carbohydrate molecules

Chemists at the California Institute of Technology have succeeded in devising a new method for building carbohydrate molecules in a simple and straightforward way that requires very few steps. The new synthesis strategy should be of benefit to scientists in the areas of chemistry and biology and in the pharmaceutical industry.

Microscopic scaffolding to house the tiny components of nanotech devices could be built from RNA

Microscopic scaffolding to house the tiny components of nanotech devices could be built from RNA, the same substance that shuttles messages around a cell's nucleus, reports a Purdue University research group.

NASA scientists have discovered a way to identify the gene functions of all of an organism's genes simultaneously

NASA scientists have discovered a way to identify the gene functions of all of an organism's genes simultaneously by using unique DNA sequences or 'bar codes.'

First licence for therapeutic cloning

Britain's Human Fertilisation and Embryology Authority has granted the first licence to create human embryonic stem cells using cell nuclear transfer – a technique also known as therapeutic cloning.

Not only has life evolved, but life has evolved to evolve

That's the conclusion drawn by two Rice University scientists who have designed a computer simulation to test the idea that evolvability — the likelihood of genetic mutation — is a trait that can itself be favored or disfavored through the process of natural selection.

Frog science helps to explain how the environment may have permanent effects on the nervous system

Scientists studying how the nervous system develops in frogs have found that altering the pattern of electrical signaling in individual neurons changes the kinds of neurotransmitters they produce.

Scientists have turned procrastinating primates into workaholics by temporarily suppressing a gene in a brain circuit involved in reward learning

Using a new molecular genetic technique, scientists have turned procrastinating primates into workaholics by temporarily suppressing a gene in a brain circuit involved in reward learning. Without the gene, the monkeys lost their sense of balance between reward and the work required to get it, say researchers at the National Institute of Mental Health .

Underwater experiments using the latest remote surgical technologies

McMaster’s Mehran Anvari will conduct experiments using the latest remote surgical technologies and techniques during a 10-day underwater mission taking place this October.

Stranglehold on science is choking human ingenuity

The greatest long-term risks for humanity will not come from weapons of mass destruction, global war, disease or famine, according to Donald Braben, visiting professor in UCL’s Department of Earth Sciences.

Automated science speeds solution of Human Genome data

Scientists in Argonne's Biosciences Division are automating and accelerating the complex processes that coax a protein to reveal its structure so they can learn the role Nature assigned it.

New fluorescent dye technique may provide new insight into how cancerous tumors begin and grow

A technique developed by University of California, San Diego biologists, which uses bright fluorescent dyes to reveal the activity of genes in individual cells of an organism, promises to be a boon to developmental biologists, and may provide new insight into how cancerous tumors begin and grow.

Experimental vaccine against ricin

Scientists have developed an experimental vaccine against ricin, a potential biological threat agent, which fully protected mice from aerosol challenge with lethal doses of the toxin.

Successfully cloning mice from an advanced melanoma cell

Nature can reset the clock in certain types of cancer and reverse many of the elements responsible for causing malignancy, reports a research team led by Whitehead Institute Member Rudolf Jaenisch, in collaboration with Lynda Chin from Dana Farber Cancer Institute.

First-of-its-kind noninvasive imaging technique shows two proteins interacting

Radiologists at Washington University School of Medicine in St. Louis have developed a first-of-its-kind noninvasive imaging technique that allows them to watch two proteins interacting in live animals.

Scientists create mice that don't gain weight, even when fed fat-laden, high calorie diets

By altering the expression of a single -- albeit different – gene, Drs. Roger Davis (UMASS Medical School, USA) and Ying-Hue Lee (Academia Sinica, Taiwan) have succeeded in creating two different strains of transgenic mice that don't gain weight, even when fed fat-laden, high calorie diets.
