View ArticleConverting water into hydrogen more efficiently
Scientists have long been puzzled why it is easier to produce hydrogen from water in an acidic environment than in an alkaline environment. Marc Koper comes with an explanation: the reason is the...
View ArticleSun's UV light helped spark life
High energy, ultraviolet radiation from the Sun is a known to hazard to life, yet the energy provided by our star has played an important role as the essential driver of life on Earth.
View ArticleAstrochemistry: how life may have begun in space
We usually imagine comet impacts as a threat and not as the source of life. But perhaps they were precisely that. Researchers in Bochum are looking for evidence for this theory.

Studying how our bodies metabolize lipids such as fatty acids, triglycerides, and cholesterol can teach us about cardiovascular disease, diabetes, and other health problems, as well as reveal basic...
View ArticleHydrogen bonds directly detected for the first time
For the first time, scientists have succeeded in studying the strength of hydrogen bonds in a single molecule using an atomic force microscope. Researchers from the University of Basel's Swiss...
View ArticleHow RNA formed at the origins of life
A single process for how a group of molecules called nucleotides were made on the early Earth, before life began, has been suggested by a UCL-led team of researchers.
View ArticleNew approach set to make peptide stapling widely available
UK scientists have created a new method to structure peptides, which they say will be cheaper and make the process of using stapled peptides in drug discovery much more widely available.
View ArticleFirst aid kit in some living organisms helps fix DNA after lengthy sun exposure
Sunburn in living organisms is caused by ultraviolet (UV) light from the sun damaging the DNA in the cells. Many organisms, however, have an in-built mechanism for repairing the sun damage. This is...
View ArticleBiochemists link synthetic compound to hunger-hormone production
New research suggests that a man-made cousin of a small molecule found in olive oil can disrupt the hunger-signaling pathway. Researchers identified this promising new target by screening a library of...

Proteins have the power to turbo-charge biochemical reactions inside the body.
View ArticleCould interstellar ice provide the answer to birth of DNA?
Researchers at the University of York have shown that molecules brought to earth in meteorite strikes could potentially be converted into the building blocks of DNA.
View ArticleDesigner binders protect silicon battery electrodes
In your electric car's battery, swapping an electrode with one made of silicon could let the battery store 10 times more energy. Why isn't silicon used? It falls apart. Scientists designed binders,...
View ArticleCooking fats in the atmosphere may affect climate more than previously thought
Fats being released into the atmosphere from cookers such as deep fat fryers may be enhancing the formation of clouds, which have a major cooling effect on the planet.
