Solar activity reconstructed over a millennium

An international team of researchers led by ETH Zurich has reconstructed solar activity back to the year 969 using measurements of radioactive carbon in tree rings. Those results help scientists to better understand the dynamics ...

Forests go into growth 'overdrive' to recover from drought

One in 12 people could face severe drought every year by 2100, according to a recent study. And water stored on two-thirds of the Earth's land surface will shrink as the climate warms. As plant ecologists, we're concerned ...

Pillar-like molecules as biosensors for metabolites

Metabolites are organic molecules that take part in or are created during the biochemical reactions constantly taking place in an organism. For the human body, more than 110,000 metabolites have been identified. Metabolites ...

As sea ice disappears, a greener and browner Arctic emerges

Arctic sea ice has been in steep decline over the past two decades. A study of tundra shrubs published today in the journal PNAS shows that as sea ice disappears, the Arctic is becoming both greener and browner.

Face shields no match for sneeze vortex rings

Do face shields provide enough protection to the wearers against COVID-19 if they don't also wear a mask? Spoiler alert: no. But researchers at Fukuoka University in Japan are working to create face shields safe enough to ...

Magnetic vortices come full circle

Magnets often harbor hidden beauty. Take a simple fridge magnet: Somewhat counterintuitively, it is 'sticky' on one side but not the other. The secret lies in the way the magnetisation is arranged in a well-defined pattern ...

Irreversible hotter and drier climate over inner East Asia

Mongolia's semi-arid plateau may soon become as barren as parts of the American Southwest due to a "vicious cycle" of heatwaves—that exacerbates soil drying, and ultimately produces more heatwaves—according to an international ...
