The ‘satellite navigation’ in our brains

Our brains contain their own navigation system much like satellite navigation (“sat-nav”), with in-built maps, grids and compasses, neuroscientist Dr Hugo Spiers told the BA Festival of Science at the University of Liverpool today.

The brain’s navigation mechanism resides in an area know as the hippocampus, which is responsible for learning and memory and famously shown to be different in London taxi drivers in a Wellcome Trust-funded study carried out by Professor Eleanor Maguire at UCL (University College London).

Newly discovered molecule promises better treatments for heart attacks, heart surgery

Scientists have discovered a compound that could lead to new treatments for heart attacks as well as methods to protect hearts during open heart surgery and other situations in which blood flow to the heart is interrupted.

In the process, the researchers uncovered cellular mechanisms that help explain how alcohol can protect against heart attack damage. In addition, they have uncovered a possible key to reducing chest pain and the heart attack damage among millions of people of East Asian descent who are genetically unable to respond to nitroglycerin and other cardiovascular treatments.

Eating veggies could help with chronic lung disease

You know it’s good for you in other ways, but could eating your broccoli also help patients with chronic lung disease? It just might.

According to recent research from Johns Hopkins Medical School, a decrease in lung concentrations of NRF2-dependent antioxidants, key components of the lung’s defense system against inflammatory injury, is linked to the severity of chronic obstructive pulmonary disease (COPD) in smokers. Broccoli is known to contain a compound that prevents the degradation of NFRP.

Tuberculosis drug shows promise against latent bacteria

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. This revelation suggests that R207910 may lead to improved and shortened treatments for this globally prevalent disease.

New method for creating inducible stem cells is remarkably efficient

Some of the most challenging obstacles limiting the reprogramming of mature human cells into stem cells may not seem quite as daunting in the near future. Two independent research papers, published by Cell Press in the September 11th issue of the journal Cell Stem Cell, describe new tools that provide invaluable platforms for elucidating the molecular, genetic, and biochemical mechanisms associated with reprogramming. The new findings also offer considerable hope toward making the reprogramming process more therapeutically relevant.

Researchers find memory capacity much bigger than previously thought

Subjects in memory tests given at MIT’s Computational Vision Cognition Laboratory were asked to recall which of a pair of objects they had seen earlier that day. Subjects were shown 3,000 images, one at a time, over a five-hour period.
