But, especially since the the 1970s when brewers adopted new manufacturing techniques, beer may have lost some of its past flavor. Beer had historically been brewed in open, horizontal vats, but the industry switched to the larger, closed vessels, as seen on any present-day brewery tour. These containers are easier to fill, empty, and clean, and they enable larger brewing volumes to save costs. But this modern method can reduce the flavor produced in the process....
Not enough has happened to address the problems that caused those blackouts since. Bills have passed to help fix issues with the grid, but many claim much more needs to be done. The Texas grid operator recently warned residents that extreme heat could soon cause blackouts. Still, recently, cryptocurrency mining has been becoming a sizable industry in Texas as Texas politicians have tried to court the tech industry. The highly energy-intensive practice is reportedly exacerbating these problems using limited energy resources....
This is the driving idea behind DARPA’s Upward Falling Payloads (UFP) program, which seeks to create technologies that would allow the Navy to leave unmanned systems and other distributed technologies hidden in the ocean depths for years on end and deploy them remotely at the push of a button when the need arises. Think: unmanned aircraft that travel to the surface and launch into the sky to provide reconnaissance or to disrupt or spoof enemy defenses, or perhaps submersible or surface sub-hunters that launch from the seafloor during times of heightened alert in a particular maritime theater....
Although more than 60 percent of Americans want to see this time-switching system done away with, we aren’t there yet. Earlier this year, the Senate unanimously voted to make daylight saving time permanent, but the Sunshine Protection Act has yet to be voted on in the House. Meanwhile, the biannual time changes cause residents of 48 states to face circadian misalignment. That, essentially, means our internal clocks are out of whack....
It turns out that the news release was based on research that has yet to be published in a peer-reviewed journal and won’t be until later this year. It’s impossible to judge evidence you can’t see, and the the authors of the new research declined to provide specifics before their study comes out. So we turned to a fossil expert who walked us through what it would take to get from bone to bird....
Hubble spotted the star WHL0137-LS, nicknamed “Earendel,” which is Old English for “morning star” or “rising light,” with a combination of its powerful instruments and lucky cosmic alignment. The mass of a huge galaxy cluster, called WHL0137-08, warped space through an effect called gravitational lensing. That distorted portion of the cosmos magnified the distant star’s light, and Hubble was in the right place to get a glimpse. The findings were published Wednesday in Nature....
Many seasoned drivers remember their first car with cruise control, or air conditioning. Heck, some people who started off in a Ford Model T have even gotten the chance to sit behind the wheel of an all-electric Mustang Mach-E. Technology has changed the way that the world uses the automobile, but some of the features found in modern cars seem to be a tad egregious. According to a new study from J....
Drones, it turns out, can add a festive air to any event. For example, they’re great at playing catch … unless the thing they’re supposed to catch is a pumpkin as it’s fired out of a cannon: The video by YouTube user Ugly Tutorials says that the pumpkin was fired at up to 200 mph. It destroyed the drone and gimbal, but the GoPro recording the video survived. Perhaps, after the pumpkin-shaped onslaught of Halloween and Thanksgiving, drone pilots are looking for a little help figuring out their vehicles....
This flight is part of the broader “Collaboration Leading Operational Unmanned Development for Meteorology and Atmospheric Physics” (CLOUD MAP) project, where four universities are trying to figure out how to use drones to better study weather. Drones are ideal because they can fly above towers and below where manned aircraft and balloons operate. It’s this lower atmospheric boundary layer that the drones are built to study. “There’s an impact during what we call the diurnal cycle, the night-day boundary, the sun comes out, starts heating up the ground, and that’s where a lot of our unstable weather phenomena starts to form,” says Jamey Jacob, a professor of Mechanical and Aerospace Engineering at Oklahoma State University....
But this unique sound could be controlled by a special area of the brain. A team of researchers led by Matthew Fuxjager at Brown University and Eric Schuppe at Wake Forest University have found regions in the woodpecker forebrain which have previously only been associated with both vocal learning in animals and language in humans. Their study, published today in the journal PLOS Biology, suggests that the activity in this region of a woodpecker’s brain is associated with tree drumming, instead of vocalization like in other animals....
“Haitian Creole is here in the US. It’s this huge language. It’s the third most spoken language in Miami after English and Spanish,” says Cindy Blanco, senior learning scientist at Duolingo. “We’re encouraging learners to use Haitian Creole in those restaurants. Part of this motivation is to make sure that we’re connecting language with culture and with community.” Duolingo, created by computer scientists at Carnegie Mellon University, combines language learning with technology, incorporating techniques like machine learning, for example....
What type of solar energy capture system you put on your home depends on your needs. If you want to go full tilt and generate usable electricity from your home’s rooftop—and even possibly contribute power back to the larger grid—tried and true photovoltaic arrays might be just the ticket. A typical installation involves the panels, which are constructed of many individual silicon-based photovoltaic cells and their support structures, along with an inverter, electrical conduit piping and AC/DC disconnect switches....
When you think of dyslexia, what first comes to mind might be some form of inversion–reading backwards, that kind of thing. But dyslexia is actually a broad term to cover lots of different ways in which people with otherwise normal intelligence levels have trouble reading. That could include difficulty converting letters into sounds, difficulty spelling, and difficulty separating the phonological tones of one letter from another. The benefit of ebook readers is largely in their customization....
Here are some of our favorites. Formulated with coal tar extract, which controls itchiness and flakiness, Neutrogena T/Gel Therapeutic Shampoo can combat different scalp conditions. It tackles seborrheic dermatitis and psoriasis, the culprits behind irritated, scaly scalps, and fights off common dandruff. The gentle cleanser is safe to incorporate into your daily grooming routine and starts working after one use, slowing down the overproduction of skin cells that leads to flakes....
Dairy farming first started in the Middle East almost 11,000 years ago, before spreading through the Balkans to Greece and Central Asia. But the cheeses that sit on our grocery shelves today are nearly all Western, and that’s shaped our perception of this snack, filling, topping, and (admit it) meal. Sampling recipes from different countries can change that, however: These eight varieties helped widen my views on cheese and cheese making....
But the Model X won’t have the electric SUV market all to itself for long. The Audi e-tron quattro debuted as a concept at the Frankfurt motor show in September. The company says it will be ready for the streets by early 2018. Here’s how they stack up, keeping in mind that the Audi – while close to being the real deal – is still a concept, while the Tesla is rolling on the road already:...
On December 10, 1958, microbiologist Esther Lederberg stood next to her husband. Clad in a pale, floor-length gown, clutching a small purse in gloved hands, she gazed unsmiling into the camera. Joshua Lederberg had just won a Nobel Prize in Physiology or Medicine for his discoveries in bacterial genetics. For him, it was the spectacular peak of his career. For her, a bittersweet moment. Esther had worked with Joshua in a lab for more than a decade....
“I think traditionally people kind of considered, ‘Well, you know, kids aren’t going to get that sick with this,’” Francis Collins, the agency’s head, said in the interview. Since the pandemic began, he says, “more than 400 children have died of COVID-19. And right now we have almost 2,000 kids in the hospital, many of them in ICU, some of them under the age of four.” This means that “kids are very seriously at risk,” he said....
One of the few backups an electrical grid has to rely on to keep the lights on and the AC cranking are peaker plants—power plants that run only when the power grid cannot keep up with energy demands. The plants are turned on when the need for electricity peaks, which tends to occur in the steamy summer months, igniting rows of fume-spewing smokestacks during peak electricity usage. Jennifer Rushlow, the associate dean for Environmental Programs and director of the Environmental Law Center at Vermont Law School, explains that peaker plants are often more polluting and inefficient than other energy sources, which can make them more of a burden than benefit for local communities....
