If you want to know if a person prefers to eat veggies or meat, then you might consider analyzing his hair. This study published in Proceedings of the National Academy of Sciences show that chemical traces of proteins from food can be found in hair strands.

"This information can be used to quantify dietary trends in ways that surveys cannot capture," says distinguished professor Jim Ehleringer, of the U's School of Biological Sciences. "We would like to see the health community begin to assess dietary patterns using hair isotope surveys, especially across different economic groups within the US."

Traveling great distances while not spending much time has been man’s dream ever since the distant past. As time goes by, transportation vehicles evolve and become much faster than before, allowing us to spend less time on travel and more time on things that matter more. And it would seem that we will go much much faster in the near future. How fast? Faster than sound itself.

The private spaceflight company Virgin Galactic and Rolls-Royce have teamed up to create a supersonic jet for high-speed passenger flights.  

The Spaceship Company (TSC), Virgin Galactic's aerospace-system manufacturing arm that builds the company's SpaceShipTwo space planes, is now working to develop a high-speed commercial aircraft capable of flying at Mach 3, or three times the speed of sound.

[On Aug. 3], TSC announced the completion of a mission concept review and unveiled the initial design concept for a high-speed aircraft. They also announced that they have signed a memorandum of understanding with Rolls-Royce to collaborate in design and development for the craft.

When we hear the word “parasite”, what comes into our minds are organisms that take advantage of their hosts and make them suffer. But while some of these parasites do cause harm to other organisms and creatures, this fact is only true for 4% of known parasites. The other parasites, meanwhile, play major ecological roles. And so, in reality, while there are some parasites that are known to be dangerous and should be eradicated, there are also some parasites which are to be protected.

About a dozen leading parasite ecologists, including University of Washington's Chelsea Wood, published a paper Aug. 1 in the journal Biological Conservation, which lays out an ambitious global conservation plan for parasites.

"Parasites are an incredibly diverse group of species, but as a society, we do not recognize this biological diversity as valuable," said Wood, an assistant professor in the UW School of Aquatic and Fishery Sciences. "The point of this paper is to emphasize that we are losing parasites and the functions they serve without even recognizing it."

Everything has an ending. Even our grand universe, despite looking majestic and eternal, will end some day. But how will our universe end? That’s what theoretical astrophysicist Katie Mack writes about in her book titled The End of Everything (Astrophysically Speaking). In the book, Mack enumerates some possibilities of how our universe will end. 

But far from being depressing, Mack’s account mixes a sense of reverence for the wonders of physics with an irreverent sense of humor and a disarming dose of candor.

Some potential finales are violent: If the universe’s expansion were to reverse, the cosmos collapsing inward in a Big Crunch, extremely energetic swells of radiation would ignite the surfaces of stars, exploding them. Another version of the end is quieter but no less terrifying: The universe’s expansion could continue forever. That end, Mack writes, “like immortality, only sounds good until you really think about it.” Endless expansion would beget a state known as “heat death”...

Perhaps more merciful than the purgatory of heat death is the possibility of a Big Rip, in which the universe’s expansion accelerates faster and faster, until stars and planets are torn apart, molecules are shredded and the very fabric of space is ripped apart.

Quezon City, Philippines — A man named Dino Rivera went outside of his house to buy something from the nearby store. On his way, however, he saw something that doesn’t seem to belong in the area. That something was an ostrich, and it was running fast towards the other side of the street.

Not much is known about the said flightless bird, but it is assumed that somehow, it broke free from the place where it was kept.

That, or someone played Jumanji.

What are your thoughts about this one?

Dr. Quentin J. Lee is principal of Childersburg High School in Alabama, and is doing his best to promote and enforce new safety rules as school opens for the fall to the tune of "Can't Touch This" by MC Hammer. If it takes a catchy song to explain social distancing, mask wearing, and hand washing, he's game to do it. He pulled it off well! -via reddit

Dr. Lee's previous video about COVID-19 is pretty good, too.

The area known as Alabama Hills is not in Alabama, and there aren't many hills, either. There you'll find a crop of rounded rock formations that proved to be quite useful. It's where you can place antagonists on different levels, hide them from each other, stage an ambush, shoot from safety, and convince whoever sees it that these rocks exist where you say they do.

These strange rock formations are versatile actors, having played Colorado, Arizona, Wyoming, Mexico, Spain, Iran, Afghanistan, India, and China—not to mention distant planets, alternate dimensions, and fantasy realms. It would be impossible to list all the screen legends that have shared scenes with these majestic bowed rock arches and potato-shaped stones, but they include Spencer Tracy, Errol Flynn, Clint Eastwood, Lucille Ball, Cary Grant, Cesar Romero, Natalie Wood, and Russell Crowe.

As of 2019, it’s been 100 years since the earliest confirmed filming in the area.

With a history like that, it's no wonder there's a film festival nearby, with tours to the rocks themselves. Read about Alabama Hills and its cinematic history at Atlas Obscura. And then keep your eye out for them during your next movie night.

Serial record-breaker David Rush has been practicing his poker chip stacking skills for about a year and a half. After that long time of training, Rush is now able to stack the poker chips at an amazing speed. Just a few days ago, he attempted to break the world record of the most number of poker chips stacked with one hand in a minute, which was 42.

The serial record-breaker said he managed to stack 49 chips, but the last was placed just after the time ran out, making his new record 48. The stack was able to remain standing on its own for at least 5 seconds, qualifying for the record.

David Rush currently has broken over 150 Guinness world records.

A truly amazing man.

Nikolai Rimsky-Korsakov’s Flight of the Bumblebee is already a very difficult piece to play on normal instruments such as the piano, violin, and wind instruments such as the trombone. But this trombonist, named Martyn Stroud, decided to take things to an entirely new level by playing the piece on a watering can.

Blowing into a trombone mouthpiece attached to the end of a watering can’s neck, [he] manages to emulate the frantic sound of the buzzing musical bumblebee.

We’re very impressed.

When someone dies in their 90s, or even older, people aren't all that curious about what caused their death. After all, there is a limit to how long a human body can last, and death in a person who has achieved an extremely advanced age is not a surprise. But what does it really mean to die of old age? Gizmodo spoke to four experts about that. University of California, San Francisco, professor of medicine Elizabeth Dzeng says, in part,

It’s common, in our society, to say that someone “died of old age.” But nobody ever actually dies of “old age.” There are always other pre-existing diseases—or new diseases—that cause the deaths in question. “Old age” isn’t something you’d put on a death certificate—most likely, it would be something like cardiac arrest, which occurs due to some underlying issue such as an infection, heart attack, or cancer. For example, a clot could go into the lungs which prevents somebody from oxygenating their brain or their body, and which then causes the heart to stop. When somebody dies, whether or not they’re young or old, some disease or disease-process has caused their body to stop working.

There's more, and they also address aging, filling out a death certificate, and the idea of dying peacefully in your sleep at Gizmodo.

Sandra and Lloyd Simpson adopted more than two dozen children in the 1970s and '80s, to add to several that Sandra gave birth to. That was something that Toronto had never seen, and won't likely see again. But Sandra saw the need in Canda's foster care system, then in Vietnamese refugee children, and in international adoptions that didn't work for other people.

With their sprawling numbers and the haphazard way they came together, the Simpsons pressed up against the boundaries of what it meant to be a family. They arrived in Forest Hill in 1978 like an asteroid, crashing into a wealthy white neighbourhood that had never seen so many Brown faces before, let alone enough Brown faces to field both sides of a baseball game, and all under one roof. They embodied a particular strain of mid-century Canadian liberalism—a belief that the complications and inconveniences of race could simply be discarded and replaced with a new collective identity.

Talk to the Simpsons today and they’ll say they were just like any other family. Over the course of 20 years in the big house on Russell Hill Road, they played on soccer teams and got into fistfights, snuck around with boyfriends and delivered newspapers. They experienced joy as well as tragedy—troubles with the law, illness and disability.

Now, 40 years later, the Simpson kids have grown into chefs, business owners, athletes, hospitality workers and parents with kids of their own. And they’ve had time to reflect on the singularity of their childhood and of their mother’s vision, and on the peculiar moment in time that allowed their family to flourish. Sandra pushed the limits of adoption so far that her motivations still seem alien, even to her own children. “To tell you the truth, she’s not normal,” her daughter Kathryn told me. “I don’t think anyone could really explain her.” She had a unique brand of stubborn, no-nonsense altruism that persevered in the face of bigoted NIMBYism. What happened on Russell Hill Road is not just the story of an extraordinary woman, but of a radical experiment in child rearing. Sandra Simpson didn’t keep the suffering of the world at a distance. She invited it into her home and made it family.

Mississippi is getting a new flag. The Commission to Redesign the Mississippi State Flag will select a new design from submitted entries by September, and the state's citizens will have a referendum to accept or reject the new flag during the November election. The deadline for submissions was August first, and now those hundreds of submission are in a gallery for public view. The only rules are that the design must contain the words "In God We Trust," and that no Confederate flags are used. You can "♥" flags, but that probably won't have any sway over the commission. Most of the submissions are straightforward, many with magnolia blossoms, but the few posted here show that there is a wide range of inspirations. -via Metafilter
