Scientists reveal the most distant galaxy we’ve ever found: ScienceAlert

The galaxy whose light has traveled nearly 13.5 billion years to reach us has been confirmed to be the oldest galaxy found to date. By studying the galaxy’s oxygen content using the Atacama Large Millimeter/Subarray Array (ALMA), astronomers have precisely dated it to just 367 million years after the Big Bang, a time when the … Read more

Losing weight is one of the most common New Year’s resolutions, and yet it’s the one most of us struggle to achieve. By the time the second or third week of January rolls around, many of us find it difficult to commit to the lifestyle changes needed to lose weight, or at least keep it … Read more

Mysterious white clouds keep appearing near the Bahamas, and no one knows why: ScienceAlert

The slice of ocean wedged between Florida and the Bahamas is one of the most well-studied marine environments in the world, yet it’s also the center of an enduring geological puzzle. Since at least the 1930s, scientists in the area have observed eerie, billowing white clouds appearing in the calm surface of the turquoise water. … Read more

This asteroid lasted for 4 billion years. That could be a big problem: ScienceAlert

A huge amount of rock and other material flows around our solar system as asteroids and comets. If one of those comes towards us, can we successfully prevent an asteroid collision with Earth? Well maybe. But there appears to be one type of asteroid that is particularly hard to destroy. Asteroids are chunks of rocky … Read more

Physicists break the record for firing lasers in their university lane: ScienceAlert

Physicists have just set a new record by confining a self-focusing laser pulse to a cage of air, along a 45-meter (148-foot) long university corridor. With previous results well below a metre, this latest experiment led by physicist Howard Melchberg of the University of Maryland (UMD) breaks new ground for trapping light in channels known … Read more

This is certainly true of the age-old question of how often one should change up one’s exercise routine. Unfortunately, there is … Read more

Scientists have built a microscopic tractor beam using laser light: ScienceAlert

Tractor beams make intuitive sense. Matter and energy interact with each other in countless ways throughout the universe. Magnetism and gravity are both natural forces that can hold things together, so there is a kind of precedent. But the actual tractor beam geometry is something different. A tractor beam is a device that can move … Read more

Procrastination can be a sign of serious health problems, study finds: ScienceAlert

College students have a lot of freedom but not a lot of organization. This can be detrimental to habitual procrastinators. Studies have shown that at least half of college students procrastinate to a level that is potentially detrimental to their education. But this may not be the only negative consequence of putting things off until … Read more

There’s a simple way to offset the health risks of sitting all day: ScienceAlert

To reduce the harmful health effects of sitting, take a 5-minute walk every half hour. This is the main finding of a new study that my colleagues and I have published in the journal Medicine and Science in Sport and Exercise. We asked 11 healthy adults, middle-aged and older, to sit in our laboratory for … Read more
