If we know a protein’s structure, we can make educated guesses about its function. And by mapping thousands of protein structures, we can begin to decipher the biology of life.

The reCharge tire works like a stick of lip balm, pushing up new tread as the old stuff wears away.
Microfluidic device sheds light on how short-chain fatty acids produced by gut bacteria may influence neurological diseases.
Astronomers from the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) and CSIRO have just observed bizarre, never-seen-before behavior from a ‘radio-loud’ magnetar—a rare type of neutron star and one of the strongest magnets in the Universe.
Their new findings, published in the Monthly Notices of the Royal Astronomical Society (MNRAS), suggest magnetars have more complex magnetic fields than previously thought – which may challenge theories of how they are born and evolve over time.
Magnetars are a rare type of rotating neutron star with some of the most powerful magnetic fields in the Universe. Astronomers have detected only thirty of these objects in and around the Milky Way —most of them detected by X-ray telescopes following a high-energy outburst.
Recent advances in the field of robotics have enabled the fabrication of increasingly sophisticated robotic limbs and exoskeletons. Robotic exoskeletons are essentially wearable ‘shells’ made of different robotic parts. Exoskeletons can improve the strength, capabilities and stability of users, helping them to tackle heavy physical tasks with less effort or aiding their rehabilitation after accidents.
MIT study sheds light on the longstanding question of why cancer cells get their energy from fermentation.
In the 1920s, German chemist Otto Warburg discovered that cancer cells don’t metabolize sugar the same way that healthy cells usually do. Since then, scientists have tried to figure out why cancer cells use this alternative pathway, which is much less efficient.
MIT biologists have now found a possible answer to this longstanding question. In a study appearing in Molecular Cell, they showed that this metabolic pathway, known as fermentation, helps cells to regenerate large quantities of a molecule called NAD+, which they need to synthesize DNA and other important molecules. Their findings also account for why other types of rapidly proliferating cells, such as immune cells, switch over to fermentation.
A mitochondrial hormone expressed by cells deep in the brain appears to play a role in improving metabolism and fighting off obesity, according to a new study in mice.
A new study on the rotation of the universe’s first light could suggest physicists need new rule-breaking subatomic particles.
