Hair growing stem cells may one day provide treatments for human hair conditions

Researchers at the Howard Hughes Medical Institute at The Rockefeller University have isolated stem cells from the skin of a mouse, and showed, for the first time, that an individual stem cell can renew itself in the laboratory and then be used in grafts to produce skin, hair and oil glands.

Scientists to tackle the most common cause of diarrhoea world-wide with DNA sequencing

Returning holidaymakers may be comforted to know that travellers' diarrhoea could be a thing of the past. Scientists at the University of Birmingham's Medical School are set to sequence the DNA of the bacterium: this will identify causes of illness and point to better cures.

Ultra-sensitive measurement technique shows how biomolecular motors carry out essential tasks

In the human body, hundreds of different types of biomolecular motors help carry out such essential tasks as muscle contraction, moving chromosomes during cell division, and reloading nerve cells so they can repeatedly fire.

Mouse stem cells may help restore hearing loss in humans

The work is important because, in humans, inner ear sensory hair cells are a precious commodity. Humans are born with only about sixteen thousand of these sound detectors in each ear, which can be easily damaged by age, certain illnesses, exposure to loud sounds, and some medications. Once damaged, the cells do not easily grow back. And with the cell loss comes so-called irreversible hearing loss.

Compounds break bonds holding dangerous pollutants together

Everything from the manufacture of new materials to the creation of modern medications relies on chemicals known as metal-based catalysts. Catalysts pack a double punch: Even as they greatly increase the rate of chemical processes, they regenerate so they can be used again.

Researchers have coaxed RNA to self-assemble into 3-D arrays

These RNA structures can form a wider variety of shapes than double-stranded DNA can and are easier to manipulate than many protein alternatives.

Novel method for studying ancient life forms

Geobiologists are announcing today their first major success in using a novel method of "growing" bacteria-infested rocks in order to study early life forms.

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.

Small molecules as artificial gene regulators

Scientists have been trying for some time to develop molecules that mimic natural regulators of gene expression.

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.
