Computer model of damaged DNA bends the rules

Our knees may become stiff when injured, but banged up DNA becomes flexible, suggests the most detailed computer model of damaged DNA to date. Further, this flexibility explains how the body's enzymes recognize and fix damaged DNA.

A trip to Mars might sound appealing, but it would be a one-way-trip

A space traveller’s dream of one day holidaying on Mars might sound appealing, but it would be a one-way-trip according to Australian researchers at the University of Queensland.

Sea snail offers natural healing powers for a range of illnesses from chronic pain to diseases of the brain

A beautiful, but often deadly, snail from the sea has been revealed as a largely untapped source of natural healing powers for a range of illnesses from chronic pain to diseases of the brain.

Scientists have developed the first mouse model Werner’s syndrome

Scientists have developed the first mouse model of a rare disease in which people age rapidly and start developing cancers and other diseases associated with the elderly when they are only about 30 years old.

Antibodies produced by shark immune systems could be used to detect human pathogens

A recent discovery shows that antibodies produced by shark immune systems could be used to detect a range of human pathogens some of which have the potential to be used as biological warfare agents.

3-D technology to assist stroke patients and the disabled

For patients recovering from strokes or certain types of injuries, using repetitive and strength-building exercises to regain ranges of motion, grip and balance is an important part of the recovery process.

Scientists visualise protein complex responsible for looking after out of shape proteins

The structure of the chaperonin complex of the bacteria Thermus thermophilus reveals clues about how the important molecule may do its job of folding new or damaged proteins within cells.

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.'

British team and NASA plan to take stem cells into space

The $US1 million project aims to explore ways to protect astronauts from space radiation in preparation for a manned mission to Mars in 2020.

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 .
