Ecosystems under threat from ocean acidification

Acidification of the oceans as a result of increasing levels of atmospheric carbon dioxide could have significant effects on marine ecosystems, according researchers.

Sugar-hungry yeast to boost biofuel production

Engineering yeast to transform sugars more efficiently into alcohols could be an economically and environmentally sound way to replace fossil fuels, say scientists.

Fat clue to TB awakening

The factors instrumental in triggering latent tuberculosis infection to progress into active disease have long remained elusive to researchers.

Microbial answer to plastic pollution?

Fragments of plastic in the ocean are not just unsightly but potentially lethal to marine life. Coastal microbes may offer a smart solution to clean up plastic contamination, according to researchers.

Possible 'superbug' status for STI

The rise of multidrug resistance in gonorrhoea-causing bacteria is threatening to make this sexually-transmitted infection extremely difficult to treat.

Bacterial 'food supplements' for small algae

To boost their diet of mineral nutrients and sunlight, small algae also feast on bacteria in order to grow and fix carbon dioxide.

Vital role for bacteria in climate-change

Scientists reveal the identity of some crucial players in the gas cycle; isoprene-degrading bacteria that are able to intercept the release of isoprene into the atmosphere.

Microbes reprogrammed to ooze oil

Researchers have coaxed photosynthetic microbes to secrete oil-bypassing energy and cost barriers that have hampered green biofuel production.

Advances in improving Hep A treatment

A research article could lead to improvements in the production of vaccines for hepatitis A, the most widespread viral disease in the world.

Microbe detective seeks out germs

Microorganisms are everywhere and most of them are harmless, but they can do a lot of damage in the manufacture of pharmaceuticals or in tissue transplants.

New ways to TB

Researchers have found two novel ways of killing the bacteria that cause tuberculosis, a disease responsible for an estimated two million deaths each year.

New lentil being readied for market

'Essex,' a new lentil variety has a lot to offer: high seed yields for growers, nitrogen-fixing bacteria for wheat crops, and a tasty source...

Real-time view of cellular phenomena

Scientists have recorded the first microscopic images showing the deadly effects of AMPs, most of which kill by poking holes in bacterial cell membranes.

Bone marrow can harbour HIV-infected cells

Scientists have identified a new reservoir for hidden HIV-infected cells that can serve as a factory for new infections.

Periodontal pathogens enhance HIV-1

Although oral co-infections are highly prevalent in HIV-1 patients and appear to positively correlate with viral load levels, the potential for oral bacteria to induce HIV-1 reactivation in latently infected cells has received little...

A fingerprint for genes

Cells may not have a mouth, but they still need to ingest substances from the external environment. If endocytosis is affected, it can lead to a variety of diseases.

Vitamin D crucial to activating immune defences

Scientists have discovered that Vitamin D is crucial to activating our immune defences and that without sufficient intake of the vitamin, T cells - will not be able to fight off serious infections in the body.

Alzheimer's-associated protein may be necessary

Amyloid-beta protein - the primary constituent of the plaques found in the brains of Alzheimer's disease patients - may be part of the body's first-line system to defend against infection.
