New Research Takes Us Another Step Closer to a Hydrogen-Fuelled Future

Hydrogen has huge potential as a clean energy source, but so far we haven’t been able to make fuel cells cheaply or efficiently enough. Now scientists are using quantum technology to explore how solar power could unlock all that potential.

The key is in using nanoparticles to boost the efficiency of photoelectrochemical cells, or PECs – the panels that handle the job of converting water to hydrogen and oxygen through the process of electrolysis.

Warm Antarctica Caves Show Signs of New Species, Study Says – The Daily Beast

Warm caves under Antarctica’s glaciers may be hiding previously undiscovered plant and animal species, scientists say. A new study led by Australian National University revealed an extensive network of warm caves around Mount Erebus, an active volcano in Antarctica. Soil samples taken from the caves turned up traces of DNA that could not be identified, lead researcher Ceridwen Fraser said early Friday. “The results from this study give us a tantalizing glimpse of what might live beneath the ice in Antarctica—there might even be new species of animals and plants,” Fraser said, according to Agence France-Presse.

Soil samples taken from caves around Mount Erebus revealed unrecognizable DNA.

Lack of REM sleep linked to higher dementia risk – Futurity

People who get less REM sleep, or take a long time to reach REM sleep, may have a higher risk of developing dementia.

After adjusting for age and sex, researchers found that for every percent that REM sleep was reduced, there was a nine percent increase in the risk for all forms of dementia and an eight percent increase in the risk of dementia due to Alzheimer’s disease.

Strong Friendships In Adolescence Pay Dividends In Adulthood : Shots – Health News : NPR

Researchers have found that people with deep friendships in adolescence had less anxiety and a greater sense of self-worth in early adulthood. Close friends matter, their study found.

“The findings are giving us some good evidence for the importance of adolescent friendships, not just short-term but into adulthood,” says Catherine Bagwell, a psychologist at Emory University’s Oxford College, who was not involved with the study. “We haven’t had too many robust, rigorous findings like this.”

Ancient Science: Mysterious Babylonian Tablet Could Hold Mathematical Secrets For Today’s Researchers

The tablet was discovered in the early 1900s but researchers have since puzzled over its function.The calculations may have been used for architectural calculations when building pyramids or other structures.

“The tablet not only contains the world’s oldest trigonometric table; it is also the only completely accurate trigonometric table, because of the very different Babylonian approach to arithmetic and geometry.”
