Scientists at Scripps Institution of Oceanography are working with Antarctic tour operators like Hurtigruten to enable vacationers to serve as citizen scientists with the FjordPhyto citizen science project. Travelers collect samples of phytoplankton from Antarctic fjords in an effort to understand the base of the food web, helping scientists learn how one of the most fertile ocean regions in the world may be changing.

This iconic shot from the 1902 film A Trip to the Moon shows the fabled Man in the Moon embedded with a massive, bullet-like spacecraft that was launched from Earth by a giant cannon. (Credit: drmvm1/Flickr)
It’s been 50 years since humans first landed on the Moon. But for how long have we rehearsed those first steps in our imaginations? This we do know: We’ve been telling each other tales about our Moon-landing dreams for nearly 2,000 years.
The earliest known written story ab ...read more

Worldwide, people drink over 65 billion gallons of alcohol each year. The United States’ share, if divided equally across the adult population, would amount to about two and a half gallons of pure alcohol per person, annually. And this thirst seems to be universal: Fermented beverages have been found in nearly every society, as far back as archaeologists can detect their existence.
That’s the idea behind the “drunken monkey&rdquo ...read more
Two galaxy clusters, Abell 0399 and Abell 0401, are merging about 1 billion light-years from Earth. This image shows the clusters' cores (red) in X-ray-light. The two are linked by a thin filament (yellow and blue), which glows faintly in microwaves and radio waves.

Galaxy clusters are a great place to peer in on the physics that govern our universe. Not only are these cosm ...read more

Many marathon runners know the boost that can come from popping a mid-race energy gel. (Mmmm, calorie-rich goop.) But according to new research published in Science Advances, when it comes to endurance events, there’s a limit to how much energy th ...read more

Since 2004, the rate of death by suicide has exceeded that of death by combat injury for American soldiers. A review of more than 100 cases involving the suicide of an active-duty soldier found a significant association between firearm ownership, access and usage patterns and increased risk of suicide.
The study, published today in the open-access, online-only journal JAMA Network Open, conducted psychological autopsies of 135 U.S. soldiers who committed ...read more

NASA astronaut Scott Kelly spent a year in space while scientists monitored changes in his body, as well as that of his twin, Mark Kelly, who remained on the ground. Kelly came back to Earth in good shape, the experiment showed. And, some Russian cosmonauts have also spent even longer than Kelly in space without obvious long term ill effect from ...read more
Recent analysis of Planck data upholds mysteries that have existed since the spacecraft’s first results in 2013. (Credit: ESA/Planck Collaboration)
During its time in orbit, the European Space Agency's Planck spacecraft gave humanity the most sophisticated measurements ever made of the cosmic microwave background (CMB) radiation, the first flash of light that rippled across the universe after the Big Bang. Plank told us the shape of the universe and confirmed crucial components of the B ...read more
Though researchers don't know why methane levels are currently rising, the fossil fuel industry was likely to blame in the past. (Credit: Nick Stubbs/Shutterstock)
Carbon dioxide is climate change’s villainous star. But methane, an even more potent greenhouse gas, is CO2’s lesser-known evil twin. Researchers now find methane levels in the atmosphere are on an escalating upward trend. That’s a problem because emission scenarios that limit global warming to 2 degrees Celsius a ...read more
Your stress may be contagious to your dog. (Credit: Klymenok Olena/Shutterstock)
A knowing glance. A paw on your arm. A lick on the cheek. Most dog owners can recall a time when they were feeling down. And somehow, their dog just knew something was wrong and responded with a loving gesture.
Many dog lovers have long believed that canines are able to sense human emotions. And, a growing body of evidence on the emotional connection between man and his best friend adds weight to these heart ...read more
