Bacteria use density switch to balance virulence and growth

Pathogens are becoming more and more resistant to antibiotics. With the goal of developing new therapeutic approaches to treat bacterial infections more effectively in the future, researchers at the Karlsruhe Institute of Technology (KIT) and the Max Planck Institute in Marburg investigated the plague-related bacterium Yersinia enterocolitica.

Can cannabis use disrupt women’s fertility? New study finds strong evidence

Researchers found that THC, the psychoactive compound in cannabis, alters oocyte gene expression, spindle formation, and chromosome segregation, lowering embryo euploidy rates in IVF. This provides direct human evidence linking cannabis exposure to impaired female fertility outcomes.

Study maps gene activity across pregnancy breastfeeding and post-weaning stages

In a study in mice, researchers have identified genes associated with the dramatic transformation of the mammary gland in pregnancy, breastfeeding, and after breastfeeding as it returns to its resting state.

Exosomes carry key indicators of biological aging

A new research paper featured on the cover of Volume 17, Issue 8 of Aging (Aging-US) was published on July 30, 2025, titled "Exosomes released from senescent cells and circulatory exosomes isolated from human plasma reveal aging-associated proteomic and lipid signatures."

New technique succeeds in studying embryo implantation outside the body

The use of assisted reproductive technologies like in vitro fertilization is becoming more common worldwide. However, while these technologies successfully create viable embryos, a little over half of all embryos are lost because they fail to implant into the uterus.

Exploring testosterone's influence on cardiovascular, metabolic, reproductive, and mental health

For decades, testosterone has been recognized as the primary driver of male reproductive development and secondary sex characteristics.

Ultra-processed foods affect sperm quality and metabolism even without extra calories

A controlled crossover trial in Cell Metabolism found that ultra-processed foods increase weight, fat mass, LDL:HDL cholesterol, and alter reproductive hormones in men, with some effects independent of calorie load. These diets also showed trends toward reduced sperm motility, shifts in pollutants, and transient inflammatory responses, highlighting risks beyond excess calories.

Male and female bovine embryos show distinct development paths

Cornell researchers have uncovered the genetic triggers that cause male and female bovine embryos to develop differently, as early as seven to eight days after fertilization.

Disrupting protein quality control slows tumor growth in pediatric rhabdomyosarcoma

A new research paper was published in Volume 16 of Oncotarget on August 29, 2025, titled "In vivo manipulation of the protein homeostasis network in rhabdomyosarcoma."

Adjusting fertility drug timing boosts ovulation success in rat models

Researchers at Osaka Metropolitan University have found that changing the timing of fertility drugs to match the follicle maturity period significantly increases the number of ovulated oocytes-the cells that develop into eggs-during artificial fertilization, even in rats that typically produce few oocytes.

Research examines how cancer may invalidate forensic age-estimation tools

Patients with solid tumors, including breast and lung cancers, showed only slightly less accurate results. In contrast, individuals with blood cancers, particularly chronic lymphocytic leukemia (CLL) and acute myeloid leukemia (AML), sometimes had large errors, with ages overestimated by as much as 50 years.
