Organ rejection culprit identified

When a mouse's immune system is deciding whether to reject a skin graft, one powerful member of a molecular family can help the graft survive.

Menopausal brain change

Many women experience menopausal changes in their body including hot flashes, moodiness and fatigue, but the changes they don't notice can be more dangerous.

Perfecting a solar cell

New research shows that a film of carbon nanotubes may be able to replace two of the layers normally used in a solar cell, with improved performance at a lower cost.

Antibiotics paradox

While consumers are increasing demand for pork produced without antibiotics, more of the pigs raised in such conditions carry bacteria and...

Nanoparticle drug delivery

Engineers have created the first synthetic nanoparticles that can penetrate a cell without poking a hole in its protective membrane and killing it.

Blocking malaria transmission

By disrupting the potassium channel of the malaria parasite, a team of researchers has been able to prevent the malaria parasites from forming in mosquitoes.

Surprising graphene

Graphene is the two-dimensional crystalline form of carbon: a single layer of carbon atoms arranged in hexagons, like a sheet of chicken wire with an atom at each nexus.

New pathogen from pigs' stomach

Scientists have isolated a new bacterium in pigs' stomachs thanks to a pioneering technique, offering hope of new treatments to people who suffer with stomach ulcers.

Quasiparticle finding

Weizmann Institute physicists have demonstrated, for the first time, the existence of 'quasiparticles' with one quarter the charge of an electron.

Treating autoimmune disease

In autoimmune diseases, the immune system turns against the body's own tissues and organs, wreaking havoc and destruction for no apparent reason.

New device reliably couples gas chromatography columns

Once again, the major equipment suppliers have chosen Pittcon to launch their latest innovations. Sean Ottewell looks at some of the best in...

Bitter orange SRMs

Scientists have developed Standard Reference Materials (SRMs) for bitter orange, long used in folk medicine and now increasingly used in herbal weight-loss products.

Blood supply to medial and lateral breast tumours

The use of MRI is effective in differentiating the blood supply to medial and lateral breast tumours, which is important in treatment planning and prognosis.

Detecting prostate cancer with MRI

The use of MRI without endorectal coil can detect prostate cancer and provide undistorted images with diagnostic image quality and accurate tumour localisation.

Washing produce

Washing fresh fruits and vegetables before eating may reduce the risk of food poisoning and those awful episodes of vomiting and diarrhoea. But it may not be enough.

Microscaffolding therapy to treat stroke damage

Scientists are developing cell-scaffold combinations that could be injected into the brain to provide a framework inside the cavities caused by stroke.

Message system controls adult stem cells

British researchers have uncovered a messaging system that instructs ASCs to contribute to tissue repair in response to chemical signals in the body.

Stem cells and cancer

If a crucial gene called Apc is lost or damaged, its normal function of controlling the adult stem cell population breaks down.

New electronic system

Scientists have created and tested a set of computer programs that use electronic medical records to help clinicians detect contagious illness.

Sweet nanotech batteries

Nanotechnology could improve the life of the lithium batteries used in portable devices, including laptop computers, mp3 players, and mobile phones.
