As people search for solutions to the climate change crisis on Earth, scientists are working to create renewable energy sources as alternatives to fossil fuels. Now, scientists at Stanford University hope to offer a new solution as they are developing a single device that collects solar energy and shoots radiation out into space – acting as both a heater ...read more

Forming an Ocean
When you look out at the ocean, it’s difficult to imagine the swaying body of water being any other way. But, says a team of researchers, some of the H2O that covers much of our planet’s surface was once something very different: A stream of hydrogen traveling through the galaxy. Only on Earth did this hydrogen mix with oxygen to create the watery world we know today ...read more
A new study finds that an imbalance between one’s circadian rhythm and eating and sleeping habits may contribute to weight gain. (Credit: Pakula Piotr/Shutterstock)
Our weight might not be controlled solely by what we eat. When we eat, and when we get to sleep, may be just as important. A small study published this week in Current Biology found people who had been thrown off their circadian rhythms burn more calories in the late afternoon and evening hours than in the morning, ...read more

On Aug. 4, 1972, the crew of a U.S. Task Force 77 aircraft flying near a naval minefield in the waters off Hon La observed 20 to 25 explosions over about 30 seconds. They also witnessed an additional 25 to 30 mud spots in the waters nearby.
Destructor sea mines had been deployed here during Operation Pocket Money, a mining campaign launched in 1972 against principal North Vietnamese ports.
There was no obvious reason why the mines should have de ...read more
Using a small lava cove as trap, a small number of bulls have learned to round up pelagic yellowfin tuna, driving them into shallow nooks, where the exhausted fish often leap ashore in a last ditch attempt to escape. The oldest bull eats his fill after dispatching the prey with bites to nape and throat, while younger bulls take the scraps. (Credit: Tui de Roy)

It’s one of the cardinal rules of shipping something fragile: The more tightly you pack your cargo, the better its chances of reaching its destination in one piece. It turns out, the same rule applies for mailing mosquitoes, according to a new study in the Journal of Insect Science.
While your average Joe probably isn’t sending off boxes of the blood suckers (at least, let’s hope not), scientists sometimes need to ship live batches. Often, ...read more
Mid-September in Maine is a time when there is some relief from hot days, but there is no real sign of the leaves changing color just yet. On a beautiful Saturday morning in Brunswick (a small mid-coast town known for Bowdoin College), the Curtis Memorial Library held its annual How-To Festival, which brings together local businesses, organizations, and individuals. Attendees share their skills and knowledge of doing all things under the sun, ranging from every day activities to v ...read more
Last year, astronomers announced they’d detected a comet from another solar system: ‘Oumuamua. (Credit: NASA/ESA/STScI)
On October 19, 2017, astronomers first saw an object from another solar system traveling through our own. Zipping into our solar system from above, the interloper, now known as 1I/2017 U1 (‘Oumuamua), swung around the Sun and shot away again, never to return once it leaves our neck of the woods for interstellar space once more.
What have we learned about thi ...read more

A new report finds people spread through the Americas in multiple independent, relatively quick migrations. The discovery contrasts the notion that the peopling of the continents took the form of a slow expansion from the northern regions of modern day Alaska into South America as populations grew.

When the Americas were first settled, sometime in the past 25,000 years, it happened from the top down. Eurasians made their way across the Beringian land bridge (or followed the coastline, what’s known as the Kelp Highway hypothesis) from Siberia to Alaska and spread throughout their new territory.
Once they were her ...read more
