A forest of nanorods

By using glancing-angle deposition, researchers can create a forest of nanorods on a target surface, which offers a range of potential applications including nanosensors and fuel-cell cathodes. This technique extends shadowing effects to higher temperatures, leading to larger-diameter nanorods with unique properties.

Berkeley Lab scientists open electrical link to living cells

Researchers at Berkeley Lab have designed an electrical link to living cells, allowing for the transfer of electrons across a cell membrane. This breakthrough could yield cells that can read and respond to electronic signals, leading to new biotechnologies such as self-replicating solar batteries and more efficient energy production.

New regulator of circadian clock identified

Researchers at Concordia University have discovered how the brain chemical dopamine regulates daily sleeping and eating patterns by altering PER2 protein activity. The study, published in Journal of Neuroscience, may have implications for individuals with Parkinson's disease who experience disrupted 24-hour rhythms.

'Reaper' protein strikes at mitochondria to kill cells

Researchers found that the Reaper protein triggers apoptosis by interfering with inhibitor of apoptosis proteins and delivering its death sentence to the mitochondria. By targeting the protein to the mitochondrial membrane, it can be made more effective at killing cells, providing a potential new approach for cancer treatments.

Study shows malaria deaths in India massively underestimated by WHO; figures for adult malaria deaths worldwide now need urgent revision

A new study reveals that malaria deaths in India are 13 times higher than currently estimated by the World Health Organization (WHO). The research suggests that approximately 205,000 malaria deaths occur annually in India before age 70, with a cumulative probability of death from malaria at 1.8% for individuals under 70 years old.

Psychologists at the forefront of weight management

The authors highlight the importance of mental health care providers in addressing eating and weight-related problems in young people. Family-based behavioral interventions are considered the first-line treatment for pediatric overweight, promoting small changes in dietary and physical activity behaviors.

How batteries grow old

Ohio State University researchers conducted experiments to test commercially available Li-ion batteries thousands of times, finding irreversible changes at the nanoscale that lead to battery loss of charge. The study suggests that coarsening of electrode materials may be responsible for this loss.

The hair brush that reads your mind

Researchers developed a novel 'brush optrode' that threads fibers through hair to improve functional near-infrared spectroscopy (fNIRS) signal levels 3-5 fold. The device increases scalp contact, enhances brain imaging, and is more comfortable for patients compared to conventional fiber ends.

Long distance, top secret messages

Physicists at Georgia Tech have developed a critical component of a quantum repeater, allowing for secure encryption key transmission over longer distances. The new technology enables the relay of entangled particles over 1,000 kilometers, significantly improving the security of quantum cryptography.
