A new study is presenting a radical new theory of aging, suggesting two competing theories are actually intertwined. And even more controversially, the billions of dollars being invested in anti-aging treatments may be targeting the wrong mechanism.

In a move akin to puncturing an egg yolk without breaking the shell or egg white, researchers have figured out how to pierce the nucleus of a cell without hurting the rest of the structure. The breakthrough could be big news for medical treatments.

Scientists have discovered the largest known protein in biology. Given the fun name of PKZILLA-1, the protein was found in algae cells and helps them make toxins that are responsible for mass killings of fish.

The 3D printing of certain items could soon get a lot faster, simpler and more eco-friendly. That's because scientists have developed a new 3D printing ink which is easily extruded as a liquid, then solidifies on contact with a saltwater solution.

There could soon be a non-toxic, longer-lasting and less-smelly alternative to DEET for repelling mosquitos. Scientists have created genetically engineered human skin bacteria that are unappealing to the irritating and disease-spreading insects.

A wearable ultrasound patch could soon be saving lives, by monitoring the blood flow in hospital patients' brains. The device is only about the size of a postage stamp plus it works continuously, unlike traditional methods.

A new biodegradable plastic embedded with spores of plastic-eating bacteria manages to break down 90% of the material after five months in landfill. Weirdly, this actually made the plastic tougher and stronger during use.

Even when it’s ground into microparticles, 97% of an algae-based plastic biodegrades in compost and water in under seven months, a new study has reported. The researchers hope their plastic will eventually replace existing petroleum-based ones.

A new technique, which involves melting bacterial DNA found in blood samples, could deliver diagnoses of potentially fatal infections faster than ever before. Results may be obtained in a few hours, instead of days.

Researchers have created an ultra-thin sensor that can wirelessly record deep brain activity down to a resolution of one or two neurons. The device has potential applications in conditions such as epilepsy, Parkinson’s disease, and chronic pain.

Researchers have created a thin transparent neural implant that can monitor activity on the brain's surface but also account for functions at a deeper level. The hope is that it will lead to an accurate but less invasive brain-computer interface.

It’s not often that space throws something entirely new at you, but in 2019 astronomers discovered a completely unknown phenomenon they called odd radio circles (ORCs). Now, more data may have revealed just how these rare objects form.
