New mechanism for cancer progression discovered by UNC and Harvard researchers

Researchers at UNC and Harvard have discovered a new alternative mechanism for activating the Ras protein, which plays a crucial role in cellular growth control. The discovery, published in Nature Structural and Molecular Biology, shows that modification of Ras with ubiquitin can activate it, leading to cancer formation.

Enzyme explains angina in diabetics

A new study published in Circulation reveals that the arginase enzyme may play a key role in the development of cardiovascular disease in patients with type II diabetes. Inhibiting this enzyme improves blood vessel function in diabetics with angina, but has no effect on healthy individuals or those without angina.

New method for diagnosing malaria

Researchers at Aarhus University have developed a new, simple and sensitive method to diagnose malaria infections using an enzyme-based technology called REEAD. This method can detect relatively low infection counts and also identifies resistant Plasmodium parasites, making it suitable for large-scale screening projects.

How infidelity helps nieces and nephews

A University of Utah study supports the theory that men help their sisters' children because they are more likely to carry genes from their mother. The new mathematical model relaxes assumptions previously made, showing that men are more likely to share genes with their sister's kids than under the old theory.

4 is the 'magic' number

A new study suggests that the human mind can cope with a maximum of four chunks of information before confusion sets in. Professor Gordon Parker from the University of New South Wales re-analyzed experiments and found that this number is more accurate than previously thought.
