When you wake up in the morning, it might feel like your brain just switched on at the ring of an alarm, although you still might feel groggy for a while. But the actual process the brain goes through to wake up is a gradual, coordinated event. So exactly how does it happen?First, let’s define what it means to be awake. “Being awake means the brain is in a state that supports awareness, movement and thinking,” Rachel Rowe, a professor of integrative physiology at the University of Colorado Boulder, told Live Science in an email. “Unlike sleep, where brain waves…

I love the I/O on the front panel. You get three USB-A ports (5 Gbps), as well as a 10-Gbps USB-C port. The inclusion of a headphone jack and an SD card slot is also super convenient. On the back, you’ll find your usual assortment of ports, including one more USB-C port. That should cover all the bases, depending on what peripherals and accessories you use.In addition to the video ports on the back of the GPU, you’re getting upgraded port selection in the rear of the PC. For versions of the PC without discrete graphics, you now get HDMI…

After circling the central Caribbean Sea and remaining ‘near stationary’ this week, Tropical Storm Melissa is now about 160 miles (260 kilometers) southeast of Kingston, Jamaica, and drifting southeastward at 1 mph (1.6 km/h).The storm’s bafflingly slow advance, which is projected to stay below an average person’s walking speed at around 2 mph (3.2 km/h) over the weekend, could be dire for several Caribbean islands, experts warn.Tropical Storm Melissa will continue to lumber along a path somewhere between Jamaica and Haiti, with forecasters predicting a slow movement toward the northeast and north in the coming hours, and a westward drift…

When scientists sequenced the Neanderthal genome in 2010, they learned that Neanderthals interbred with human ancestors before mysteriously going extinct. As a result, many people alive today share up to 4% of their DNA with Neanderthals.This genetic breakthrough yielded powerful new information about the evolutionary history of Neanderthals and Homo sapiens, but it also raised a new question: Could we bring back Neanderthals?George Church, a Harvard University professor of genetics, answered this question in the affirmative in an interview with Der Spiegel in 2013. Church said that, by chopping the Neanderthal genome up into thousands of chunks and reassembling them…

What to Look for in a Laptop StandAccordionItemContainerButtonWhen shopping for a laptop stand, think about how and where you’ll use it, and how much you’re willing to spend.

Napoleon Bonaparte’s disastrous invasion of Russia in 1812 saw his massive “Grande Armée” almost destroyed by hunger, enemy attacks and the brutal winter. But now, scientists have identified another deadly force that left the French army on its knees — two previously unsuspected diseases.Researchers already believed that infectious disease played a role in the French army’s destruction, and it was long thought that typhus and trench fever killed thousands of French soldiers. But a new analysis of a mass grave in Lithuania filled with the skeletons of French soldiers hasn’t found traces of any of the bacteria that cause these…

Jim Sanborn couldn’t believe it. He was weeks away from auctioning off the answer to Kryptos, the sculpture he created for the CIA that had defied solution for 35 years. As always, wannabe solvers kept on paying him a $50 fee to offer their guesses to the remaining unsolved portion of the 1,800-character encrypted message, known as K4—wrong without exception. Then, on September 3, he opened an email from the latest applicant, Jarett Kobek, which started, “I believe the text of K4 is as follows …” He’d seen words like this thousands of times before. But this time, the text…

Quick factsWhat it is: HH 211, a baby star erupting with gargantuan energy jetsWhere it is: 1,000 light-years from Earth in the constellation Perseus.When it was shared: Sept. 17, 2025Most events in the universe are not fully understood, including the relatively simple process of star formation. Stars form in dense clouds of cold gas and dust. When these clouds reach a threshold mass, they collapse under their own gravity, leading to the birth of a baby star, or protostar.As these young stars form, they pull matter from their surroundings, developing a swirling disk of gas and dust around them known…

Microphones are common on most headphones and earbuds, but on gaming-specific headsets you’re more likely to find boom mics sticking out from one of the ears. These tend to provide better audio quality, as well as a few other features you may want to consider when buying a new headset.The first is a visual indicator for whether your mic is muted. I know that sounds a little funny, but it serves a dual purpose of letting you know that you’re being heard when you’re talking, and also ensuring your friends don’t hear you snacking. This might be a light, or…
