In the human species, bigger brains suggest better brain health and cognitive function. And since the 1930s, our brains have been growing. Now, a new study shows how this is affecting our risk of developing dementia, particularly Alzheimer's disease.

Eating a keto diet prevented the mild cognitive impairment often seen in the early stages of Alzheimer’s disease, new research has found. The researchers suggest that adopting the diet may be a way of delaying the onset of full-blown Alzheimer's.

The 102-year-old tuberculosis vaccine shrank liver cancer tumors in mice, which suggests it may be replicated in a human trial. If this was the case, the vaccine might prove successful in tackling this notoriously hard-to-treat cancer.

Researchers have identified an accurate ‘signature’ that may signal a person’s risk of dementia five to 10 years before symptoms appear. The biomarker could provide an early diagnosis, allowing therapeutic interventions to slow the disease’s progress.

Research has found that some personality traits increase the risk of a dementia diagnosis, whereas others reduce it. The findings suggest that targeting these traits earlier in life may be a way of reducing dementia risk in the long term.

For centuries red wine has been thought to trigger headaches more than other drinks, and it's been unclear exactly why this is the case. Now researchers think they've solved the mystery, and the culprit is a chemical previously thought to be beneficial.

The way a sunflower bends to follow the Sun across the sky each day can be quite dramatic. Now, scientists have uncovered something equally dramatic: it does it through unique genetic transcription, which rewrites what we know about its special Sun dance.

Natural sugar allulose is 70% as sweet as table sugar, with only 10% of the calories, and does not affect blood glucose or insulin, making it an ideal sugar replacement. Yet producing it has been a huge roadblock. Scientists say they've cracked the code.

Using a method of total-body imaging, researchers have measured and tracked the body’s immune response to viral infection. It's a promising platform for studying human immunity in greater detail and may assist the study of other infectious diseases.

Researchers have identified a gene in golden retrievers associated with long life that’s related to a gene that causes cancer cells to grow quickly in humans. The discovery has the potential to help our furry besties and us.

Engineers at UC Davis have developed a new radar sensor that can pick up movements just 100th the width of a human hair. Better yet, the sensor itself is only the size of a sesame seed and is energy efficient.

As temperatures climb, so does violence. At least that's the conclusion reached by researchers looking at how ancient cultures in the south central Andes responded to climate change about 1,000 years ago. It may be an important cautionary tale.
