A loss of smell can be one of the earliest warning signs of Alzheimer’s disease, but the cause of this sensory change have been unclear. Now, a study reveals that the problem may not lie in the nose or olfactory bulb itself, as previously thought.

In a breakthrough, scientists have transferred a courtship behavior from one species to another, triggering the recipient to perform this completely foreign act as if it was natural. It's a feat that has never been genetically engineered before.

A massive study has found that ADHD medication has a real-world social impact – for the those on the drugs and the wider community. In nearly 150,000 newly diagnosed people, medication appeared to offer sweeping benefits beyond just symptom management.

Just a few days after scientists announced we're at a pivotal tipping point in Alzheimer's disease research, a team has made a huge breakthrough, proving that mitochondrial dysfunction fuels memory loss. Then they engineered a way to restore it.

We've long known how the nerve endings in our skin detect cold and swiftly relay the information to our brains, but we haven't understood exactly how it works. Scientists have now solved the puzzle, unlocking the mystery of this temperature pathway.

In a first-of-its-kind study, researchers zoomed in on PTSD at the single-cell level to better understand how it affects the brain. The findings revealed how trauma can lead to specific molecular changes in some brain cells.

In a comprehensive new study looking at 39,763 different foods and drinks from the biggest 25 companies in the country, scientists discovered that almost 20% rely on synthetic food dyes to attract consumers. Now, the fight is on to ban them for good.

Remarkable new findings about the sugar stores in neurons have unlocked an entire new method of treating cognitive decline, and it furthers our understanding of why GLP-1 weight loss drugs appear to provide a shield against Alzheimer's disease.

For the first time, Cortical Labs' mini-brain system has shown how its breakthrough biological computer system can, in response to drug intervention, alter activity and improve performance. It's a huge milestone for synthetic biological intelligence.

Exposure to common metals has again been linked to ADHD and specific symptoms. It builds on existing research that has found a strong association between environmental contaminants like lead and a higher rate of people diagnosed with the condition.

We all know the many health effects that a diet high in saturated fat and refined sugar has on our bodies. Now, in the first study of its kind on humans, scientists find that it may also be negatively impacting our ability to navigate and learn.

Scientists have uncovered an odd superpower triggered by tapping your finger to a beat – it may help you understand someone talking to you in a noisy place, like at a busy cafe. While it sounds a little woo-woo, there's emerging science behind it.
