NewsStrongest hints yet of biological activity outside the solar system
Astronomers have detected the chemical fingerprints of dimethyl sulfide (DMS) and/or dimethyl disulfide (DMDS), in the atmosphere of the exoplanet K2-18b. On Earth, these are only produced by life, primarily microbial life such as marine phytoplankton.

NewsFrequent use of antibiotics in infants and young children may increase risk for asthma, allergies and other conditions
Researchers have found that repeated antibiotic use before age 2 is associated with a higher risk for asthma, food allergies and hay fever later in life. These findings also applied to siblings who had different experiences with antibiotics.
