NASA’s planetary defence mission was a success

NASA’s planetary defence mission was a success

Testing humanity’s ability to prevent the kind of disaster that wiped out the dinosaurs, NASA intentionally crashed its DART probe into an asteroid. The threat of a devastating asteroid may seem fanciful, but scientists understandably want to prepare for a dinosaur-esque situation. It’s for this reason that, last November, NASA launched...

This eye implant could cure blindness for millions of people

This eye implant could cure blindness for millions of people

Scientists in Sweden have developed a bioengineered cornea that can successfully restore sight. It’s made from proteins in pigskin, which are a by-product of the food industry. For the millions of people across the globe who are blind or have impaired sight as a result of damage to their corneas (a progressive condition known as keratoconus), a breakthrough development from scientists in Sweden may pose a solution. One that’s both environmentally...

There may be no link between serotonin levels and depression

There may be no link between serotonin levels and depression

A major review of 17 existing studies has uncovered ‘no convincing evidence’ depression is caused by a chemical imbalance. According to new research, depression may not be caused by low levels of serotonin. The finding comes after University College London conducted a major review of 17 existing studies and realised there was ‘no convincing evidence’ linking the mental health condition with a chemical imbalance. This has prompted

Scientists believe ‘space bubbles’ could help ease climate change

Scientists believe ‘space bubbles’ could help ease climate change

Researchers at MIT are advancing a concept to slow or potentially reverse climate change. It involves placing massive silicon bubbles at the direct point between the sun and our planet. Admittedly, this concept is a little wacky, but when we hear that research in the field of solar geoengineering is advancing to help stop climate change… it’s something we’ve got to look into. Last week, a group of scientists at MIT...

Innovative ‘sand battery’ is green energy’s beacon of hope

Innovative ‘sand battery’ is green energy’s beacon of hope

Two young engineers have succeeded in using sand to store energy from wind and solar by creating a novel battery capable of supplying power all year round. When you think of batteries, you probably think of lithium. If you’re old enough to remember when one started corroding inside your CD player or GameBoy, the idea of using batteries might bring back some sad childhood memories. Lithium batteries don’t hold much energy...
