Scientists say the ozone may be fully healed within 50 years
Before climate change dominated headlines globally, our deteriorating ozone was the prime ecological concern. Decades later, scientists now claim a full recovery could be on the cards before the century’s end. There’s belief bubbling that in the foreseeable future we may actually save ourselves… from ourselves. Amid the constant, demoralising talk...

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...
Misinformation about psychedelic therapy threatens its future
Ever since hallucinogenic drugs started being reconsidered as a potential treatment for mental illness, hype surrounding their integration into modern medicine has been rife. A new paper argues that this excitement could send us back to square one. For the last two years, I’ve written extensively about hallucinogenic drugs....
Scientists have found a way to turn plastic into diamonds
By recreating the extreme conditions of exoplanets, a team of researchers have successfully managed to produce nanodiamonds from PET plastic. As the climate disaster worsens, our need for technological solutions becomes more urgent. Over the last decade, research into climate innovation has produced a mixed bag of results despite the...
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...
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...
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...
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.

NASA plans to send swimming robots to habitable ocean worlds
Most nearby planets thought to be habitable are completely covered in water. With many taking years to get to, NASA has secured funding for a project that will help us get a look into their depths. As humans come to grips with the possibility of one day living on another planet, whether willingly or out of necessity, space experts are wasting no time trying to locate our options. Mars is –...
Drug that increases human lifespan to 200 years is in the works
Taken in pill form, the drug would eliminate cells in the human body that are responsible for advancing the ageing process – potentially doubling our lifespan. But is this desirable? Are you ready to live an additional hundred years? British computational biologist Dr Andrew Steele has published a new book on the longevity of human life, arguing it is entirely feasible for us to live well beyond a single century with...
