Why we have chins

University of Iowa researchers found that human chins are an evolutionary adaptation, emerging as faces became smaller. The study suggests that mechanical forces like chewing did not create the chin, but rather a geometric change in face shape led to its development.

Scientists uncover gene 'architects' responsible for body's blueprint

Researchers have discovered two protein 'architects', MOZ and BMI1, which play opposing roles in guiding embryonic development. These proteins regulate Hox gene expression, ensuring the correct formation of body segments and tissues. The study sheds new light on how environmental factors can impact early embryo development.

Heart cells regenerated in mice

Scientists at the Weizmann Institute of Science have successfully regenerated heart cells in adult mice using a previously unknown signaling pathway. By activating ERBB2, a protein that plays a role in heart development, researchers were able to induce cardiac cell renewal and regeneration without excessive growth or scarring.

Tango dancing benefits Parkinson's patients

A new study by McGill University researchers found that a 12-week tango course improved balance and functional mobility in 40 Parkinson's patients, while also showing modest benefits in cognitive functions. The dance style's social interaction and physical activity may have therapeutic value for PD patients.

Eating out = high blood pressure?

A recent study by Duke-NUS Medical School researchers found an association between meals eaten away from home and high blood pressure in university-going young adults. The study, which surveyed over 500 participants, showed that pre-hypertension was prevalent in 27.4% of the population, with men more likely to be affected than women.

Telomeres and cancer mortality: The long and the short of it

A recent study published in the JNCI: Journal of the National Cancer Institute found a surprising association between shorter telomeres and decreased cancer mortality. The researchers analyzed data from two prospective cohort studies involving over 64,000 individuals and discovered that those with longer telomeres had higher genetic sc...

A new beginning for baby mosasaurs

A new study has discovered that mighty mosasaurs, which could grow up to 50 feet long, likely gave birth to their young in the open ocean, not on or near shore. This groundbreaking finding answers a long-held question about the initial environment of this iconic predator.
