How 'slippers' can end mascara irritation

Scientists at the University of Liverpool have developed a cheaper and more reliable alternative to animal testing, involving miniscule protozoa. The test showed significant variations in population growth according to mascara brand, with some killing the protozoa and others not harming them at all.

Parkinson's patients utilization of deep brain stimulation treatment reduced in demographic groups

A study published in Neurology found disparities in the utilization of deep brain stimulation (DBS) treatment among Parkinson's patients, with those from lower socioeconomic backgrounds and minority-serving physicians facing significant barriers. DBS out-of-pocket costs are a contributing factor to these disparities.

Reconstructing the New World monkey family tree

After landing in South America, monkeys forged their own niches, evolved new forms, and spread to Caribbean and Patagonia. The study reveals how primate migration and evolution in the Americas were influenced by ancient climates, geology, and geography.

Sex matters for microbes

African sleeping sickness is caused by single-celled parasites that mate and swap genes through a process known as sexual reproduction. This study reveals sex to be a regular part of the trypanosome life cycle, enabling new combinations of genes that could lead to disease-causing strains.

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'.

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.
