Marine reserves are increasingly important for species that are being forced by climate change to move to a new home, adapt to new conditions or die. Biologists have now compared the relative benefits of large and small protected areas in perpetuating populations. Interestingly they have also found a coral species that has developed the “skills” [...]
Researchers hope they have begun paving a new pathway in the fight against drug dependence. Their hypothesis — that increasing the normally occurring process of making nerve cells might prevent addiction — is based on a rodent study demonstrating that blocking new growth of specific brain nerve cells increases vulnerability for cocaine addiction and relapse.

Combining tamoxifen, the world’s most prescribed breast cancer agent, with a compound found in the flowering plant feverfew may prevent initial or future resistance to the drug, say researchers. The finding provides new insight into the biological roots of that resistance, and also tests a novel way to get around it.

Researchers created a computer modeling of the structural malfunctioning of the ApoE4 protein when it enters into contact with the amyloid beta molecule, the main cause of Alzheimer’s disease. The research supports experimental evidence that links ApoE4 with this pathology and opens up new exploration possibilities in understanding and fighting against the disease.

Armies of networked computers that have been compromised by malicious software are commonly known as Botnets. Such Botnets are usually used to carry out fraudulent and criminal activity on the Internet. Now US computer scientists reveal that the honeypot trap designed to protect computers from Botnets are now vulnerable to attack because of advances in [...]

As many as one quarter of the star clusters in our Milky Way — many more than previously thought — are “invaders” from other galaxies, according to a new study.

A mother’s nurture may provide powerful protection against risks her baby faces in the womb, according to a new article. The research shows that fetuses exposed to high levels of stress hormone — shown to be a harbinger for babies’ poor cognitive development — can escape this fate if their mothers provide them sensitive care [...]

The incidence of diabetes is rising worldwide. Using genetic engineering techniques in pigs, scientists at in Germany have created a new model of this metabolic disorder, which recapitulates many features of the disease, and promises to contribute significantly to improvements in diagnosis and therapy.

Scientists — using a new cooling method they created — have uncovered the inner workings of a key iron-containing enzyme, a discovery that could help researchers develop new medicines or understand how enzymes repair DNA. Taurine/alpha-ketoglutarate dioxygenase, known as TauD, is a bacterial enzyme that is important in metabolism. Enzymes in this family repair DNA, [...]
