Daily life aboard the International Space Station moves fast. Really fast. Traveling at approximately 17,000 miles per hour, 300 miles above the Earth, astronauts watch 16 sunrises and sunsets every “day” while floating around in a box with a handful of people they depend on for survival.
Often during the day I feel the need to have a bit of a lie-down. Whether it’s been a busy day, I didn’t sleep well the night before, or for no particular reason I know of. But some will warn that you’ll be ruined for sleep that night if you nap during the day.
Blooming spring flowers signal the beginning of spring, but for millions of people, they also signal the onset of the misery: allergy and asthma season. Itchy, watery eyes; sneezing, runny nose; cough and wheezing are triggered by an overreaction of the body to pollen.
Early in the 20th century, Alois Alzheimer first described a disorder of progressive memory loss and confusion in a 50-year-old woman. After she died, he examined her brain and saw that it was full of unusual protein clumps, known as plaques. Over a century later, we know that these plaques are full of a protein called beta-amyloid and are a hallmark of the disease that bears Alzheimer’s name. While other features of Alzheimer’s disease have been discovered, the theory that beta-amyloid is the main cause of this incurable disease has dominated.
Trying to keep up with what constitutes a “healthy” diet can be exhausting. With unending options at the supermarket, and diet advice coming from all directions, filling your shopping trolley with the right things can seem an overwhelming task.
Most people probably don’t think of everyday activities – such as hanging out the washing or putting away the groceries – as having an effect on their long-term health. But new research suggests that doing lots of these light-intensity physical activities reduces your risk of cardiovascular disease.
Always had the idea that the hours you spent behind your Nintendo, Xbox, PC or Playstation must have been good for something? You can now provide that vague notion with a scientific basis. A recently published study in the Journal of Communication shows that a certain type of intelligence increases through gaming.
Noninvasive treatment improves memory and reduces amyloid plaques in mice. By exposing mice to a unique combination of light and sound, MIT neuroscientists have shown that they can improve cognitive and memory impairments similar to those seen in Alzheimer’s patients.
For the past three decades or so, the conventional wisdom has been that drinking alcohol at moderate levels is good for us. The evidence for this has come from many studies that have suggested the death rate for moderate drinkers is lower than that for non-drinkers. In other words, we thought moderate drinkers lived longer than those who didn’t drink at all.
Whether playing video games has negative effects is something that has been debated for 30 years, in much the same way that rock and roll, television, and even the novel faced much the same criticisms in their time.
If you’ve ever wondered whether you could make a real contribution to the world but aren’t sure you have any really meaningful talents, perhaps you should look at how you play computer games. A growing body of research suggests that the virtual world can show you what you are truly capable of.
Have you recently carried heavy shopping bags up a few flights of stairs? Or run the last 100 metres to the station to catch your train? If you have, you may have unknowingly been doing a style of exercise called high-intensity incidental physical activity.
It’s that time of year when many are trying, and some are failing, to live up to their New Years’ resolution of losing weight. Many of these probably include resolutions to be more physically active in striving for this goal. But first, there are some common misconceptions about exercise and weight loss that need to be addressed.
The brain has no nociceptors – the nerves that detect damage or threat of damage to our body and signal this to the spinal cord and brain. This has led to the belief that the brain feels no pain. A belief that has entered popular culture.
