We live in an age of information. In theory, we can learn everything about anyone or anything at the touch of a button. All this information should allow us to make super-informed, data-driven decisions all the time.

The recent inquest into the death of Natasha Ednan-Laperouse from anaphylaxis after eating a Pret A Manger baguette she was unaware contained sesame, could lead to a change in labelling legislation. Indeed, a recent investigation found that undeclared allergens were present in a quarter of foods sampled. But a more fundamental issue needs to be addressed: why are more people experiencing severe food allergies than ever before?

Healthy sleep leads to healthy brains. Neuroscientists have gotten that message out. But parents, doctors and educators alike have struggled to identify what to do to improve sleep. Some have called for delaying school start times or limiting screen time before bed to achieve academic, health and even economic gains.

How long humans and other warm-blooded animals live—and when they reach sexual maturity—may have more to do with their brain than their body, according to a new study.

Modern medicine’s ability to keep us alive makes it tempting to think human evolution may have stopped. Better healthcare disrupts a key driving force of evolution by keeping some people alive longer, making them more likely to pass on their genes. But if we look at the rate of our DNA’s evolution, we can see that human evolution hasn’t stopped – it may even be happening faster than before.

A glucose-powered biofuel cell with electrodes made from cotton fiber could someday help power medical implants such as pacemakers and sensors.

Recent headlines claim that a glass of wine or a pint of beer a day shortens your life. It’s enough to dampen any thoughts of a celebratory drink or two at Christmas. But those conclusions are based on a partial view of the alcohol debate.

Heart attacks happen more frequently in winter, a major Swedish study has confirmed.

Bacteria are everywhere, including in and on our bodies. There are estimated to be as many bacteria in a human body as there are human cells.

Sleep has become widely recognised as playing a really important role in our overall health and wellness – alongside diet, stress management and exercise.

The Fountain of Youth may still be a myth, but a longer life expectancy is now a reality.

If you think you don’t have viruses, think again. It may be hard to fathom, but the human body is occupied by large collections of microorganisms, commonly referred to as our microbiome, that have evolved with us since the early days of man. Scientists have only recently begun to quantify the microbiome, and discovered it is inhabited by at least 38 trillion bacteria. More intriguing, perhaps, is that bacteria are not the most abundant microbes that live in and on our bodies. That award goes to viruses.

Changing the clock causes a temporary state of misalignment in our internal biological time. We may not feel ready to go to bed an hour earlier and our alarms will wake us up before we’ve had enough sleep.

Being depressed can negatively affect your appetite and what you eat, but can bad eating habits bring your mood down? Our latest study, a systematic review of the best available evidence, found a clear link between the quality of a person’s diet and their risk of depression. And it goes beyond the effect of diet on body size or other aspects of health that can affect mental health. 

It’s better light, not worse behavior, that explains crimes on a full moon
