Assisted reproduction may be linked to birth defect syndrome

Researchers have found a possible association between IVF and an increased risk of Beckwith-Wiedemann syndrome (BWS), a genetic disorder that can predispose children to cancer. BWS is characterized by excessive growth and occurs in about 1 in 15,000 births, with the incidence being significantly higher among IVF-conceived babies.

Virus decimates algal blooms

Biologists have found that viruses can destroy entire algal blooms within days, particularly when nutrients are depleted. Free-living cells are highly susceptible to viruses, which break down the cell content and dissolve it in seawater.

New genetic option for thwarting cancer

Researchers have discovered a new genetic mechanism to prevent cancer development by targeting the Cdk4 gene. The study showed that knocking out this gene can make cells resistant to cancer even if their tumor suppressor defense is deficient. Cells then enter senescence, offering a promising new option for cancer therapy.

Researchers link teen sex to early friendships, steady dating

A study by Ohio State University researchers found that teens with friends in higher grades were more likely to have sex in early adolescence. Additionally, going steady in early adolescence significantly increased the odds of having sex. The study suggests a significant minority of youth engage in sex outside of relationships.

Study finds relationship between geriatric frailty, biology

Researchers found associations between altered physiologic systems and geriatric syndrome of frailty in a study of 5,888 community-dwelling individuals. The study suggests that understanding the biology of frailty can help develop interventions to better care for older adults.
