Meta-analysis reveals drivers of antibiotic resistance in infants

A meta-analysis of genetic studies analyzing the microbiota (bacteria in the gut) of 1,275 infants from 10 countries finds that cesarean delivery and antibiotic use are driving the increase of antibiotic resistance genes load among infants, according to new research being presented at this year's ESCMID Global Congress (formerly ECCMID) in Barcelona, Spain (27-30 April).

New system personalizes chemotherapy doses for cancer patients

When cancer patients undergo chemotherapy, the dose of most drugs is calculated based on the patient's body surface area. This is estimated by plugging the patient's height and weight into an equation, dating to 1916, that was formulated from data on just nine patients.

Giant virus takes down deadly brain parasite

The single-celled organism Naegleria fowleri ranks among the deadliest human parasites. Researchers around Matthias Horn and Patrick Arthofer from the Center for Microbiology and Environmental Systems Science at the University of Vienna, in an international collaboration, have discovered viruses that infect this harmful microbe.

Research links Y chromosome decline to patrilineal societies

The emergence in the Neolithic of patrilineal social systems, in which children are affiliated with their father's lineage, may explain a spectacular decline in the genetic diversity of the Y chromosome observed worldwide between 3,000 and 5,000 years ago.

Timelapse breakthrough: Scientists capture secrets of early embryonic cell division

The beginning of life is shrouded in mystery. While the intricate dynamics of mitosis is well-studied in the so-called somatic cells – the cells that have a specialized function, like skin and muscle cells – they remain elusive in the first cells of our bodies, the embryonic cells.

Study discovers hidden mechanism behind rapid COVID variants

The SARS-CoV-2 virus that causes COVID has the unsettling ability of often generating variants of itself. Other viruses also mutate, but as SARS-CoV-2 quickly spread throughout the entire human population during the pandemic, killing millions, the virus' dynamic evolution posed a serious problem: it repeatedly challenged our bodies' immune response fighting the virus and hindered the process of getting updated vaccines ready.
