China is using DNA samples to try to re-create the faces of Uighurs The news: Chinese researchers are using blood taken from Uighurs to try to work out how to use a DNA sample to re-create an image of a personâs face, according to an investigation by the New York Times. The samples are being gathered in Tumxuk, a city in Chinaâs Xinjiang region, where a million or more ethnic Uighurs, a persecuted

Fixing photosynthesis by engineering it to recycle a toxic mistake The worst, most important enzyme often uses the wrong chemical. We fixed that. The vast majority of life on Earth depends, either directly or indirectly, on photosynthesis for its energy. And photosynthesis depends on an enzyme called RuBisCO, which uses carbon dioxide from the atmosphere to build sugars. So, by extension, RuBisCO
'In a Tropical Forest' (Struggle between Tiger and Bull) by Henri Rousseau (VCG Wilson/Corbis) The modern world gives us such ready access to nachos and ice cream that itâs easy to forget: Humans bodies require a ridiculous andâfor most of Earthâs historyâimprobable amount of energy to stay alive. Consider a human dropped into primordial soup 3.8 billions years ago, when life first began. They wou
What really happens when we make and store memories has been unravelled in a discovery that surprised even the scientists who made it. The US and Japanese team found that the brain "doubles up" by simultaneously making two memories of events. One is for the here-and-now and the other for a lifetime, they found. It had been thought that all memories start as a short-term memory and are then slowly
The chemist who gave us the artificial leaf has genetically engineered bacteria to absorb hydrogen and carbon dioxide and convert them into alcohol fuel. When Harvard Professor of Energy Daniel G. Nocera announced he was working with bacteria last year, other scientists cautioned it would be difficult to achieve a productive level of efficiency. At the time, Nocera was aiming for 5 percent efficie
CRISPR, a new genome editing tool, could transform the field of biologyâand a recent study on genetically-engineered human embryos has converted this promise into media hype. But scientists have been tinkering with genomes for decades. Why is CRISPR suddenly such a big deal? The short answer is that CRISPR allows scientists to edit genomes with unprecedented precision, efficiency, and flexibility.
