A study carried out in Finland and Sweden shows these results stem from the heat and light in these urban areas, altering the way these bugs behave. These behavioral differences could be the case for many other species that depend on temperature to know when seasons are changing. “This situation, where animals use day length to tell what time of year it is, and sort of make seasonal decisions, is a really common one,” says Matthew Nielsen, a physiology researcher at Stockholm University, and one of the authors of the study....

The bill is designed to encourage the fledgling private space industry. Among other things, it extends a sort of “grace period” that gives spaceflight companies the right to launch rockets with as little government oversight as possible, and gives companies property rights to the resources they mine from asteroids or other celestial bodies. Congress passed the bill earlier this month, and with Obama’s signature, it’s officially a law. The asteroid resources portion of the bill may cause an uproar overseas, particularly in Russia and China....

The first stages of construction will mostly involve putting in roads and power supplies. But when the telescope begins operating in 2021, GMT is expected to be the largest optical telescope on Earth–at least for a little while. It will produce images 10 times sharper than Hubble. The GMT will combine seven giant mirrors to create a lens that’s about 85 feet in diameter. By comparison, the world’s current largest telescope of this type–the Great Canary Telescope in Spain–has an aperture of just 34 feet....

SAMSUNG Galaxy Tab S7 Plus, 12.4″, 128GB Mystic Black (Wi-Fi), S Pen Included $499 (Was $699) The biggest deal we saw in Walmart’s tablet section was this Samsung Galaxy Tab S7 Plus, which is $200 off its $699 retail price. This tablet is like a mullet: both business and party combined. Use it for sending emails on-the-go, or demolish a few games of Contexto to get the leftover tryptophan fog out of your brain....

One of the problems with the beer flavor wheel is that it’s not particularly consumer-friendly. A brewer with at least a passing interest in chemistry will be able to recognize flavor/aromas such as “isoamyl acetate” (that’s the banana ester so very prevalent in, say, German hefeweizens.) But your regular beer drinker is probably not going to have a clue what that means. Beer writer Mark Dredge, who has a book, Craft Beer World, coming out soon, decided to make a more consumer-friendly beer flavor wheel....

Go ahead, love your movie stars and politicians. But don’t turn to them for scientific guidance, says the group Sense About Science. The Celebrities and Science Review 2008 has compiled the unsubstantiated claims that famous folks let loose on the public this year.Speaking of frauds, could a grandfatherly tortoise perpetrate one? We don’t think Jonathan the giant Seychelles tortoise meant to pull one over on anyone, but it turns out he might not be who people was thought to be....

You can go to a gas station, a smoke shop, or even online to purchase some of the hemp-derived products. But, there are tons of sketchy products on the market due to loose restrictions. Currently, delta 8 THC lives in a gray area of whether it is federally legal or not. The 2018 Farm Bill legalized the production of hemp products and derivatives that have lower than 0.3% delta 9 THC....

This spiffy little terrier is volunteer number one on day number one of an ambitious project launched by Harvard University evolutionary neuroscientist Erin Hecht to answer basic questions about what dogs do and why they do it. She plans to collect data on the psychology and behavior of hundreds of them across all breeds over many years: how easily they make friends, how well they behave, how they feel about vacuum cleaners....

Click here to see all of PopSci’s COVID-19 coverage. As the highly infectious delta variant of the novel coronavirus spreads, COVID-19 cases in the United States have continued to tick upwards. The number of new cases reported daily has increased fourfold over the last month, prompting the New York Times to comment that “the national outlook is worsening quickly.” Several states with unvaccinated hotspots, such as Florida, have been hit particularly hard....

But doctors disagree over the link between sexual activity and prostate cancer. While a 2002 paper in the journal Epidemiology backs the BJU study, a 2004 study in the Journal of the American Medical Association (JAMA) and a 2003 paper from the Australian Cancer Council Victoria claim that frequent masturbation and intercourse actually decreases the risk of prostate cancer. The BJU study, conducted by a team from the University of Nottingham in England, looked at one group of 431 men who had been diagnosed with prostate cancer before the age of 60, and 409 men who did not have the disease....

Although we’ve never detected dark matter, scientists know that it exists, and there are several theories as to what it’s like. It seems the stuff doesn’t interact with light, but gravity does have an effect on it. Now, in the Astrophysical Journal, one scientist has calculated that a planet’s gravity could give dark matter a hair-like shape. Simulations done in the 1990s suggested that dark matter moves around us in massive streams, some as large as our solar system....

Last night, Musk took to his Twitter account to ask people what they’d like to see in the upcoming software update (7.1) to the Tesla Motors touchscreen dashboard user interface (UI). Many asked for features that accounted for families that share a car or drive with multiple people in the car at once. While others wanted additional features for the HomeLink screen: Some specifically sought new navigation options: Others wanted support for Apple’s CarPlay and Google’s Android Auto, the new systems that let your smartphone take over your car’s dashboard screen....

In a nod to the Corn Belt, President Trump told crowds Tuesday evening that he has directed the Environmental Protection Agency to make a rule allowing year-round sales of gasoline containing up to 15 percent ethanol, or E15. Ethanol, a grain-based alcohol, is controversial among renewable fuel advocates, farmers, environmentalists, and petroleum groups. While ethanol fermented and distilled from corn is considered a renewable fuel because corn growth, which removes carbon dioxide from the air during photosynthesis, offsets carbon dioxide emitted during combustion, its production also takes a sizable toll on the environment....

For 12 years now, my lab team has used ultrasound to control cells in many animals. We even tweaked worm DNA to trick their neurons into action. When the high frequencies hit, the worms switched direction. We never thought to test this method on flora until one of my postdoctoral fellows, Corinne Lee-Kubli, received a touch-me-not plant as a gift. As a defense mechanism, its leaves fold inward when stroked or shaken....

This advice certainly comes from a good place. But it’s also fundamentally wrong. This is not to say that tetanus isn’t as bad as parents promise. In North America, the Cleveland Clinic estimates, 10 percent of cases are fatal. In countries with inadequate or inaccessible medical care, the number is believed to be much higher. Even survival takes its toll. On Friday, the U.S. Centers for Disease Control and Prevention released a new installment in its “Notes from the Field” series about an unvaccinated 6-year-old boy in Oregon who contracted tetanus after he got a cut in his forehead....

The result is a to-scale panorama that overwhelms and immerses the viewer. And while creating experiences on this scale has been interesting for some of Asisi’s past projects, it could be critical for the Great Barrier Reef, the subject of his newest work. Right now, corals all over the world are dying at an unprecedented rate, and their disappearance could hasten the destruction of one of the planet’s most diverse ecosystems....
