New chemical method makes it easier to select desirable traits in crops

phys.org

Crops increasingly need to thrive in a broader range of conditions, including drought, salinity, and heat. Traditional plant breeding can select for desirable traits, but is limited by the genetic variation that already exists in plants.…

A tug-of-war explains a decades-old question about how bacteria swim

phys.org

Scientists have uncovered a new explanation for how swimming bacteria change direction, providing fresh insight into one of biology's most intensively studied molecular machines.

Laser pulse 'sculpting' unlocks new control over particle acceleration

phys.org

In high-intensity laser–matter interactions, including laser-induced particle acceleration, physicists generally want to work with the highest possible focused laser peak power, which is the ratio of energy per unit area to pulse duration.…

Photographing climate change: Ice porters on the frozen Chadar river

phys.org

Every winter in the Ladakh region in northwest India, the two roads that connect the small villages in the Zanskar Valley with the rest of the country close, overwhelmed by snow. But for centuries, locals have had a workaround: a road of…

How Mycobacterium tuberculosis safeguards itself from foreign DNA
