Malaria medicine and new antibiotics

A team of University of Illinois microbiologists have developed a way to mass-produce an antimalarial compound, potentially making the treatment of malaria less expensive.

Controlling protein activity

Investigators have found a way to quickly and reversibly fine-tune the activity of individual proteins in cells and living mammals, providing a powerful new laboratory tool.

Gene for corn ear formation

A team of plant geneticists have identified a gene essential in controlling development of maize, widely planted crop world-wide and a mainstay of the global food supply.

Extensive RNA regulatory networks

Scientists have succeeded in tracing intricate biochemical networks involving a class of proteins that enable genes to express themselves in specific tissues at particular moments in development.

Cancer-causing gut bacteria exposed

Scientists have discovered that a molecule produced by a common gut bacterium activates signalling pathways that are associated with cancer cells.

Bacteria protect against diabetes

Recent research has shown that mice exposed to common stomach bacteria were protected against the development of Type I diabetes.

New HPV test for developing countries

A new HPV test developed specifically for use in regions of the world with scarce resources is "substantially" more accurate in identifying women with cervical disease.

Herpes drug inhibits HIV

Researchers have discovered how a simple antiviral drug developed decades ago suppresses HIV in patients who are also infected with herpes.

Exposure to 1918 influenza virus activates memory B-cells

Exposure to the 1918 influenza virus makes survivors immune for the remainder of their lives. Scientist Live spoke with Dr. Chris...

Tuberculosis drug shows promise

A new study has shown that an investigational drug (R207910, currently in clinical trials against multi-drug resistant tuberculosis strains) is quite effective at killing latent bacteria.

Vaccine against HER2-positive breast cancer

Researchers have tested a breast cancer vaccine they say completely eliminated HER2-positive tumours in mice - even cancers resistant to current anti-HER2 therapy - without any toxicity.

Superbugs use poisons against defences

Colonies of hospital superbugs can make poisons similar to those found in rattlesnake venom to attack our bodies' natural defences.

Ebola cell-invasion strategy

Researchers have discovered a key biochemical link in the process by which the Ebola Zaire virus infects cells - a critical step to finding a way to treat the deadly disease produced by the virus.

Immune system targets harmful fungus

A new study shows that the innate immune system of humans is capable of killing a fungus linked to airway inflammation, chronic rhinosinusitis and bronchial asthma.

Nature still best provider of drugs

The best place to seek novel compounds for pharmaceutical drugs, alternative energy sources, and a host of industrial applications, is within natural systems that have evolved over millions of years.

Investigating the origin of life

Scientists at Penn State have developed a new computational method that they say will help them to understand how life began on Earth.

Vast health benefits of probiotic

Data from a recent study demonstrate the anti-inflammatory and pathogen protection benefits of Bifidobacterium infantis 35624, a probiotic bacterial strain of human origin.

From ulcers to cancer

Researchers have uncovered a big clue as to why some of the bacteria that cause stomach ulcers pose a greater risk for serious problems like stomach cancer than others.

New moquito virus

Researchers have identified a previously unknown virus that is infectious to Anopheles gambiae-the mosquito primarily responsible for transmitting malaria.

Bacterial pneumonia and the 1918 flu

The majority of deaths during the influenza pandemic of 1918-1919 were not caused by the influenza virus acting alone, report researchers. Most succumbed to bacterial pneumonia.
