Penn biologists show evidence of a two-sided genomic arms race involving repetitive DNA

Biological arms races are commonplace in nature. Cheetahs, for example, have evolved a sleek body form that lends itself to rapid running, enabling them to feast upon similarly speedy gazelles, the fastest of which may evade predation.

Discovery of new structure in the egg cells of zebrafish could provide insights into human reproduction

It is humbling to realize that we humans share about 70% of our genes with zebrafish. There are also a whole host of other similarities that make these small transparent fish an ideal animal model for the study of many human diseases and biological processes.

Stress may be linked with diminished ovarian reserve, animal study shows

Female rats exposed to a scream sound may have diminished ovarian reserve and reduced fertility, according to a small animal study published in the Endocrine Society's journal, Endocrinology.

Obesity plus alcohol intake may increase risk of developing alcohol-related cancer

New research being presented at this year's European Congress on Obesity (ECO) in Maastricht, Netherlands (4-7 May), suggests that being overweight or having obesity amplifies the harmful effects of alcohol on the risk of developing alcohol-related cancer, particularly in people with a high body fat percentage.

Study offers a path to closing the knowledge gap about differences in breast cancer genes

Too many women are getting unnecessary mastectomies and other invasive procedures because of a knowledge gap about differences in cancer genes. A new study offers a path to closing the gap.

Sonographers take 64% more time to scan for endometriosis than routine pelvic ultrasounds, study shows

A new study released by the University of South Australia shows that it takes sonographers 64 per cent more time to scan comprehensively for endometriosis compared to routine pelvic ultrasounds – time that private providers are not subsidised for in Medicare ultrasound rebates.

Prolonged bed rest immediately after embryo transfer linked with reduction in chances of pregnancy

Many clinical interventions used during in-vitro fertilization (IVF), including ultrasound guidance at the time of embryo transfers appear to increase pregnancy rates, however prolonged bed rest should not be recommended, finds a new study led by UCL researchers.

Anti-Müllerian hormone plays an active role in polycystic ovary syndrome

High levels of anti-Mullerian hormone (AMH) have traditionally been thought of as merely a passive byproduct of polycystic ovary syndrome (PCOS), but a new preclinical study by Weill Cornell Medicine researchers suggests that the hormone plays an active role in the disorder and may contribute to problems with ovulation and fertility.

Early menopause puts women at greater risk of dementia later in life

Women who enter menopause very early, before age 40, were found to be more likely to develop dementia of any type later in life compared to women who begin menopause at the average menopause-onset age of 50 to 51 years, according to preliminary research to be presented at the American Heart Association's Epidemiology, Prevention, Lifestyle & Cardiometabolic Health Conference 2022.
