Regular ibuprofen use can impact reproductive health in men

Men might want to rethink how often they reach for ibuprofen, with the latest research showing that it can negatively affect their reproductive health. A small study of 31 otherwise healthy men between the ages of 18 and 35 showed that taking the equivalent of three tablets of Nurofen every day for six weeks is enough to cause a problem. By administering certain doses of ibuprofen and then blood testing for levels of the drug […] See more

El Niño lets Antarctic ice shelves grow taller, even as they lose weight

A study published today is the first report using satellite measurements to gauge ice sheet thickness during ENSO variations. El Niño and La Niña are the two phases of the El Niño Southern Oscillation (ENSO), and understanding how Antarctic ice shelves respond to ENSO variability is useful to understand how global climate changes might affect ice shelves around Antarctica. “There have been some idealised studies using models, and even some indirect observations off the ice […] See more

Exercise is the anti-ageing 'cure' for the heart

But you will have to commit to getting active four to five times a week. Sitting around all the time is bad for your heart – it makes the muscle shrink and stiffen as you age. “When the muscle stiffens, you get high pressure and the heart chamber doesn’t fill as well with blood,” says Benjamin D. Levine, founder and director of the Institute for Exercise and Environmental Medicine. “In its most severe form, blood can […] See more

How Felix fell faster than a speeding bullet

Sometimes time flies past incredibly quickly – it’s been five years since Austrian daredevil Felix Baumgartner skydived from the edge of space. During his record breaking jump he not only completed the highest skydive ever attempted, but also broke the sound barrier on his way down. It’s taken until now for scientists to catch up to him and analyse the aerodynamics of his jump, and they have found a pretty amazing result – Baumgartner, with […] See more

Space junk - how it got there and what we're going to do with it

On 17 March 1958, Vanguard became the first solar-powered satellite to be launched into space. It was also destined, once its mission ended, to become the first of a less salubrious class of orbiting object – space junk. From nothing in 1958, to more than 100 million pieces of human-made space junk that orbits the Earth today. It includes dead satellites, rocket parts, fuel tanks, paint flecks, nose cones, collision debris and more. The amount […] See more

Where are the snows of yesteryear?

The ice and snow of the Rocky Mountains is rapidly vanishing due to climate change. A study in 2016 suggested that smaller snowfalls and shrinking glaciers and other icy terrain could lead to shortage of water supplies. The 1,000-year-old Arikaree Glacier in Colorado, for example, has been thinning by about 1 metre a year for the past 15 years and will disappear completely in 25 years. Most scientists believe the process is now irreversible. This film […] See more

A salad a day keeps memory okay

A recipe for a good memory might be anything with lots of leafy vegetables. An observational study from the US found that people who regularly eat their greens had a slower decline of memory and thinking skills compared to people who never or rarely eat these types of veggies. The difference was so great, the salad-lovers were the equivalent of 11 years younger in age. “Adding a daily serving of green, leafy vegetables to your […] See more

The water within Mars

The reason Earth has water and Mars is a desert may be underfoot. Tens of kilometres under the barren, dried out surface of Mars may exist the water that astronomers have long suspected it should contain but somehow lost, turning it into a lifeless desert while Earth retained its oceans and allowed life to evolve. Recent discoveries by robotic explorers and orbiters of Mars have revealed that the red planet was once blue like Earth, […] See more

Cosmic rays might lead to cloudy days - but claims of affecting climate change look exaggerated

Thousands of light years away a star meets its end, exploding as a supernova. Cosmic rays spew out of this cataclysmic event, streaming across the universe unimpeded and unchecked. And when they reach Earth, according to Danish researchers, they might cause clouds to form. However, claims that these clouds are significant factors in climate change are exaggerated, say other scientists. Cosmic rays are streams of high-energy particles released from stars, supernovae, and the corona of […] See more
