Early detection of soil-surface ozone can prevent damage to apples and grapes

Farmers and fruit growers are reporting that climate change is leading to increased ozone concentrations on the soil surface in their fields and orchards - an exposure that can cause irreversible plant damage, reduce crop yields and threaten the food supply, say materials chemists led by Trisha Andrew at the University of Massachusetts Amherst.

Food additives prove to be efficient at controlling bacteria on tomatoes preharvest

When vegetable farmers harvest crops, they often rely on postharvest washing to reduce any foodborne pathogens, but a new University of Georgia study shows promise in reducing these pathogens - as well as lowering labor costs-- by applying sanitizers to produce while it is still in the fields.

New method accurately detects single gene mutation in a pool of 10,000 cells

Rare genetic mutations occurring in cells cannot be detected by existing sequencing techniques because these methods do not have the required sensitivity.

Study demonstrates how a single gene drives changes in wild songbird's social behavior

A new study shows how differentiation of a single gene changes behavior in a wild songbird, determining whether the white-throated sparrow displays more, or less, aggression.

Combination regimen improves overall survival in acute myeloid leukemia patients

A combination regimen of venetoclax and azacitidine was safe and improved overall survival (OS) over azacitidine alone in certain patients with acute myeloid leukemia (AML), according to the Phase III VIALE-A trial led by The University of Texas MD Anderson Cancer Center.

Light impulses can be used to trigger electrical excitation in plants

Optogenetics denotes the manipulation of cellular processes by light-based biological techniques. An international research team led by the Würzburg plant scientists Rainer Hedrich, Georg Nagel and Dirk Becker has succeeded in applying this method to higher plants: Light impulses can now be used to trigger electrical excitation in plants.

Virginia Tech scientists reveal molecular cause underlying rare genetic disorder

Virginia Tech scientists have revealed how a nonfunctioning version of an ordinary gene impairs brain structure and function. The findings help explain a genetic form of microcephaly -- a condition where babies' heads are small and grow more slowly than their peers.

Study shows neo-self antibody as major cause of recurrent pregnancy loss

A research group centered around Kobe University Graduate School of Medicine's Professor YAMADA Hideto and Associate Professor TANIMURA Kenji (Department of Obstetrics and Gynecology), and Professor ARASE Hisashi et al. of Osaka University's Research Institute for Microbial Diseases have revealed for the first time in the world the high frequency of a novel autoantibody in women suffering from recurrent pregnancy loss.
