Fueling a hydrogen revolution      (via sciencedaily.com) 

Researchers show how magnetic flux sensors can be used to monitor the operation of proton exchange membrane fuel cells that run on hydrogen. By detecting changes in current, failure states due to incorrect water levels can be identified. This work may lead to cost-effective sustainable energy generation for electric vehicles.

Words are needed to think about numbers, study suggests      (via sciencedaily.com) 

Researchers have found a new relationship between counting ability of Tsimane' individuals and their ability to perform matching tasks that involve numbers up to about 25. The results suggest that in order to think about exact numbers, people need to have a word for that number.

Massive methane emissions by oil and gas industry detected from space      (via sciencedaily.com) 

For the first time ever on a global scale, using satellite imagery, scientists have quantified volumes of massive methane emissions due to fossil-fuel extraction activities and their impact on the climate. Their findings partly explain why official inventories generally underestimate the volume of these emissions. Stopping these releases, be they accidental or deliberate, would save those countries responsible billions of dollars.

How fuel poverty 'gets under the skin'      (via sciencedaily.com)     Original source 

New research shows that fuel poverty makes people's physical and mental health worse. Researchers found that not being able to keep homes warm enough affects people's levels of life satisfaction. But they also found that it impacts people's physical health by causing higher levels of inflammation, measured by fibrinogen, a blood-based biomarker.

A new approach to a $1 million mathematical enigma      (via sciencedaily.com) 

Numbers like pi, e and phi often turn up in unexpected places in science and mathematics. Pascal's triangle and the Fibonacci sequence also seem inexplicably widespread in nature. Then there's the Riemann zeta function, a deceptively straightforward function that has perplexed mathematicians since the 19th century. The most famous quandary, the Riemann hypothesis, is perhaps the greatest unsolved question in mathematics, with the Clay Mathematics Institute offering a $1 million prize for a correct proof.

COVID-19 vaccination strategies: When is one dose better than two?      (via sciencedaily.com) 

While most of the COVID-19 vaccines are designed as a two-dose regimen, some countries have prioritized vaccinating as many people as possible with a single dose before giving out an additional dose. In a new study, researchers illustrate the conditions under which a "prime first" vaccine campaign is most effective at stopping the spread of the COVID-19 virus. The team found the vaccine waning rate to be a critically important factor in the decision.
