Researchers at Ohio State University found that male mice developed squamous cell carcinoma tumors earlier and had more aggressive tumors than female mice. The study suggests that gender-linked differences in antioxidants may be the key reason behind this disparity.
A recent study published in the journal SLEEP found that healthy older men who get less nighttime sleep have lower morning testosterone levels. The study, conducted by Plamen Penev, MD, PhD, used polysomnography and wrist activity monitoring to measure sleep duration and its impact on testosterone levels.
A new study published in the journal Sleep found that sleep disturbance increases spontaneous pain in women. The study, conducted by Michael T. Smith and colleagues, used polysomnography to assess 32 healthy females and found that fragmented sleep profiles led to impaired natural pain control mechanisms.
Male crayfish bluff with weak claws to intimidate opponents and gain dominance, while females' claw size is an honest indicator of strength. This study reveals that dishonesty plays a more significant role in animal communication than previously thought.
A multi-disciplinary panel of experts from eight countries examined emergency medical responses to blast events and identified commonalities that can be used to enhance preparedness worldwide.

Researchers at the University of Bristol found that treatment with beneficial soil bacteria activated neurons producing serotonin, a key brain chemical linked to depression. This discovery sheds light on why some individuals are vulnerable to mood disorders like depression and may lead to new treatments.
Researchers found that fats in the stomach reduce vitamin C's ability to protect against cancer-forming compounds. The presence of lipids overrides the antioxidant effect, allowing harmful nitrosating species to form.
Research reveals tree frogs maintain grip by keeping toe pad angle low, detaching at 90°. Larger species adapt to grasp objects, allowing them to climb like humans.
A recent study found that reducing calorie intake later in life can induce health and longevity benefits similar to lifelong calorie reduction. The researchers discovered that certain drugs mimic this effect, which may lead to the development of new
Actigraphy is a reliable tool for evaluating sleep disorders, including advanced sleep phase syndrome, delayed sleep phase syndrome, and shift work disorder. It also helps characterize circadian rhythms and sleep patterns in patients with insomnia and hypersomnia.
A study led by USC and Harvard researchers identified multiple genetic risk factors that predict a man's probability of developing prostate cancer. The findings highlight the importance of this region in prostate cancer, providing potential tools for early screening and prevention efforts.
Seven countries have issued a declaration of co-operation on global health issues, aiming to address common threats and achieve goals through globalization.
