Restoring vision with stem cells

A new technique using human embryonic stem cells has been developed by Professor Gilbert Bernier, allowing for the production of light-sensitive retina cells. This breakthrough could lead to treatments for currently non-curable eye diseases like Stargardt disease and age-related macular degeneration.

New surfaces delay ice formation

Researchers create biphilic surface that repels water in some areas and attracts it in others, delaying frost formation even at 6 degrees below freezing. The unique condensation dynamics on the surface cause small droplets to merge and release energy, delaying freezing for over 3 hours.

Repeating aloud to another person boosts recall

A study by Professor Victor Boucher of the University of Montreal found that repeating aloud boosts verbal memory, especially when done in a context of communication. The research showed that repeating aloud to someone else increased information recall compared to repeating silently or in one's head.

Preferences for a good end-of-life experience

Researchers found that patients with advanced cancer are willing to pay more for aspects of a good end-of-life experience compared to healthy older adults. Both groups highly value high-quality healthcare experiences, including being treated with respect and receiving coordinated care. The study suggests that health reform efforts shou...

Super yellow blends for light efficiency

Researchers have developed a polymer blend that significantly improves light output from LEDs by manipulating hole-mobility and exploiting the difference in energy levels of the polymers. The optimized device achieves an ultrahigh efficiency of approximately 27 candelas per amp, outperforming a similar device using only Super Yellow.

Surgical trainees retain information, master skills better when honed beyond proficiency

A new study found that surgical trainees who continue to practice beyond achieving initial proficiency retain information longer and master surgical skills better. The study, presented at the American College of Surgeons Annual Clinical Congress, showed that overlearning can decrease the learning curve and improve overall scores.

Long-term contraception in a single shot

A team of Caltech biologists has created a non-surgical approach to deliver long-term contraception using a single shot, rendering animals infertile for up to two months. The technique targets the 'master regulator of reproduction,' gonadotropin-releasing hormone (GnRH), neutralizing its effects and preventing conception.

Tolerant immune system increases cancer risk

Researchers found that a tolerant immune system, characterized by high levels of regulatory T cells, increases the risk of certain types of cancer. The study analyzed blood samples from EPIC participants with cancer and controls, revealing a strong link between immunotolerance and increased lung and colon cancer risks.
