Novel hypotheses that answer key questions about the evolution of sexual reproduction

Researchers at Hokkaido University propose two novel hypotheses to address the 'two-fold cost of sex' in sexual reproduction. The first hypothesis suggests that meiosis eliminates harmful mutations through a process known as the 'seesaw effect.' The second hypothesis proposes that anisogamy evolved through 'inflated isogamy,' where lar...

Noise affects life on the seafloor

Research by the Alfred Wegener Institute found that low-frequency noise from human activities stresses crustaceans, mussels, and worms on the seafloor, impacting their ability to transform sediment and maintain ecosystem function. This could have far-reaching consequences for nutrient cycling and food availability in marine ecosystems.

Collaborations inspired early-career NIH grant that could lead to treatment breakthroughs for a range of medical conditions

A University of Virginia researcher has received a $1.8 million NIH grant to develop polymers that can deliver peptides as medicine, overcoming limitations such as short duration and toxicity. The project aims to create new therapeutic formulations using polymer biomaterials, which have endless design possibilities.

Steepest annual rise in advanced cervical cancer in US among White women

Advanced cervical cancer rates have been rising in the US, with a significant increase among White women and higher prevalence among Black women, particularly those in their mid-to-late 50s. The study found that obesity and older age at first birth may contribute to the rise in this type of cervical cancer.
