Turning off the 'aging genes'

A computer algorithm developed by Tel Aviv University identifies genes that could be transformed to stop the aging process. The algorithm predicts which genes can be turned off to create the same anti-aging effect as calorie restriction, potentially leading to new treatments for aging and other metabolic disorders.

Men's and women's soccer: Physical or technical?

A comparative study by Elhuyar Fundazioa found significant differences between the physical performance of men and women soccer players, with women displaying fatigue during high-intensity periods. The study also discovered no differences in technical and tactical aspects, suggesting that women play soccer 'in their own way'.

JCI early table of contents for Jan. 2, 2014

Studies in animal models reveal that mTOR activation contributes to morphine tolerance and hyperalgesia, while mitochondrial iron accumulation promotes doxorubicin-associated cardiotoxicity. These findings suggest potential therapeutic targets for improving pain management and limiting cardiotoxicity.

Survival rates similar for gunshot/stabbing victims whether brought to the hospital by police or EMS

A new study from the University of Pennsylvania found no significant difference in survival rates between gunshot and stabbing victims transported by police or EMS. The study examined over 4,100 patients and found that those transported by police were more likely to die due to their initial severity of injury.

The mouse that ROR'ed

Researchers at the University of California, San Diego School of Medicine found that combining ROR1 and TCL1 oncogenes in mice accelerates and worsens blood cancer. The study suggests ROR1 could be an important therapeutic target for patients with CLL, a common form of blood cancer affecting over 15,000 new cases annually.

Think you're an expert bettor? You're probably wrong

A study by Matthew Browne found that to demonstrate skill at horserace handicapping, bettors would need to place over 10,000 bets with net returns exceeding nine percent. This high standard of proof highlights the challenge of objectively evaluating one's own performance in highly volatile games.

Plant used in Chinese medicine fights chronic pain

Researchers from the University of California, Irvine, have identified a new natural compound in a traditional Chinese medicine plant that relieves chronic pain. The compound, dehydrocorybulbine (DHCB), acts on dopamine receptors and shows promise for treating low-level chronic pain without losing effectiveness over time.

Odor receptors discovered in lungs

Scientists have found odor receptors in lung tissue that can detect cigarette smoke and other irritants, triggering a response to constrict airways. These receptors, called pulmonary neuroendocrine cells, may be responsible for the chemical hypersensitivity characteristic of respiratory diseases such as COPD.

Want a good night's sleep in the new year? Quit smoking

New research published in The FASEB Journal found that tobacco smoke disrupts the circadian clock function in both lungs and brains, leading to reduced productivity, mood disorders, and depression. Quitting smoking may improve sleep quality and cognitive function by targeting a specific pathway involving the anti-aging molecule SIRT1.

Study on pregnancy and alcohol fails to take psychological factors into account

A recent study by Janni Niclasen found that children of mothers who consumed small amounts of alcohol during pregnancy showed improved emotional and behavioral outcomes at age seven. However, the study also highlighted the importance of considering psychological factors such as attachment between mother and child. The research, conduct...
