Magnetizing an iron-vanadium alloy with laser pulses sheds light on a promising phenomenon
To magnetize an iron nail, one simply has to stroke its surface several times with a bar magnet. Yet, there is a much more unusual method: A team led by the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) discovered some time ...

Tiny llama nanobodies neutralize different noroviruses—can they improve human anti-viral therapies?
Human noroviruses cause acute gastroenteritis, a global health problem for which there are no vaccines or antiviral drugs. Although most healthy patients recover completely from the infection, norovirus can be life-threatening ...

How algae use memory to protect against sudden changes in sunlight
Fluctuating sunlight poses a challenge for plants and green algae, which must quickly adjust their photosynthetic systems to remain efficient in changing conditions. Aiding in that response is a kind of rudimentary memory ...

Making extremely thin lubricating films predictable: Extension of the Reynolds equation by a non-linear wall slip law
When an electric vehicle accelerates, the motor generates maximum forces and enormous pressures act on the gears of the electric drivetrain. Surface meets surface, metal meets metal. If there were no lubricating film to allow ...

Study: How farmers decide to store or sell their grain
When farmers harvest their grain, they can choose to sell it right away or store it to obtain better prices later in the season. A new study from the University of Illinois Urbana-Champaign explores how Illinois corn and ...

It turns out, this plant fossil is really a baby turtle fossil
From the 1950s to the 1970s, a Colombian priest named Padre Gustavo Huertas collected rocks and fossils near a town called Villa de Levya. Two of the specimens he found were small, round rocks patterned with lines that looked ...

Measuring the distances to galaxies with space telescopes
One of the James Webb Space Telescope's science goals is to understand how galaxies in the early universe formed and evolved into much larger galaxies like our own Milky Way. This goal requires that we identify samples of ...
