The individuals in this region are genetically distinct from other populations around the world—and they seem to stand out with their hunting prowess as well. In a just-published analysis of three orca kills in Bremer Bay, marine biologists showed that pods will take down the biggest prey they can find: blue whales. It further supports the idea that orcas may be the only natural predators adult blue whales have. There’s plenty of documentation of orcas attacking other giant mammals; they’ll regularly prey on young humpback whales and full-sized minke whales....
“The collapsibility, transportability, and deployability of Miura-ori folded objects makes it a potentially attractive design for everything from space-bound payloads to small-space living to laparoscopic surgery and soft robotics,” said Levi Dudte, one of the authors of the paper. Dudte and his Harvard colleagues are far from the first people to come up with the idea of using a Miura-ori fold in a scientific context, but they did manage to create an algorithm that lets them input a desired shape, and have the computer calculate a folding pattern that can be laid out on a flat material, essentially creating a blueprint for complicated shapes like vases....
The Firearms and Weapons Prohibition Legislation Amendment Bill 2015 is an amendment to the Firearms Act 1996, with the purpose in part: “to create a new offence of possessing digital blueprints for the manufacture of firearms on 3D printers or electronic milling machines.” The law does include a few legal exemptions, including for “research purposes and public benefit” (so that police wouldn’t get penalized if they printed one, say). Without successfully claiming those defenses, printing or milling a gun in New South Wales comes with a penalty of up to 14 years in prison....
In November, the spike in illnesses led to a 65 percent increase in the sale of children’s fever reducers and medications compared to November 2021, according to the Consumer Healthcare Products Association (CHPA). The association represents some of the companies that make the medications including Tylenol manufacturer Johnson & Johnson, Haleon the maker of Advil, and Perrigo, which manufacturers generic store brands. In a statement, CHPA said that it doesn’t yet have a timeline for when the supply may catch up with demand and stressed that the manufacturers were working to replenish the medications as quickly as possible....
A solution, then, might be found in an adaptive smart material that does both: a substance that keeps heat out in the summer and keeps heat from getting out in the winter. Thanks to a material that can switch between two phases—a material that was tested atop a professor’s house—researchers in California have developed such a roof coating. They published their work in the journal Science on December 17. “The whole point of our work is that our roof works not only in hot weather, but also in cold weather,” says Junqiao Wu, a materials scientist at the University of California, Berkeley, and Lawrence Berkeley National Laboratory, and one of the researchers behind the project....
The incident occurred during the initial part of Delta Flight 89’s trip from LA to Shanghai on January 14. When the aircraft was about 70 miles away from LAX, the flight crew told air traffic control that it had a problem with one of the Boeing 777’s two engines and was coming back. The wide-body aircraft can stay aloft with just one in an emergency. Before it landed back in Los Angeles, it dumped fuel at an altitude of some 2,300 feet, showering communities below with the substance....
These plant spikes screw directly onto the top of water bottles, making them an extremely convenient choice for plants that get very thirsty. Terracotta is solid yet porous, which means water will release slowly throughout the spike, for a more even application, rather than delivering watering to one single location. These glass-blown orbs add a pop of color to any home garden or houseplant collection. Flip them upside-down and fill with your desired amount of water, before sticking directly into the soil....
Prochlorococcus are the most numerous photosynthesizing organisms in the world. They suck up carbon dioxide, just like plants, storing the carbon in their cells. And they release oxygen into the atmosphere. In short, these tiny bacteria play a huge role in supporting a habitable planet. Scientists at Macquarie University wondered if the millions of tons of plastic sinking into the seas each year could pose a threat to these crucial organisms....
The polar ice has been thinning steadily over the years. Where there used to be thick ice, composed of layers formed over multiple years, nowadays the polar region is largely covered with single-year ice, a much thinner and more temporary layer that’s replaced every year. This less durable stuff is significantly more prone to melting away — which is exactly what it’s doing. In 2007, the melt came within 700 miles of the pole....
Under these guidelines, far fewer African American smokers are eligible for lung cancer screenings, according to a new study. That may be because screening guidelines are based on the amount a person smokes or has smoked and their age. Research shows that African American smokers have different behaviors than white smokers—they tend to smoke fewer cigarettes, but have a higher risk of lung cancer. They’re also less likely to successfully quit smoking, and often are diagnosed with cancer younger than white smokers....

Crowd at American Airlines Center (Actual Measurement: 115 dB) Ahead of the 2011 NBA playoffs, Dallas Mavericks owner Mark Cuban had the team’s home stadium outfitted with a revamped acoustics system. Microphones in the backboards transmitted sneaker squeaks and players’ voices through 60 gargantuan speakers, which also amplified and circulated sounds from the crowd. Fans couldn’t get enough of the din. As time expired and Dallas emerged victorious after a seemingly impossible comeback, the audience roared at 115 decibels—exactly the threshold for human pain....
That’s the lesson that researchers in Australia have been teaching goannas, Australian monitor lizards that are distantly related to Komodo dragons. In a paper published today in Biology Letters researchers revealed a new way to combat the effects that the highly toxic and invasive cane toad has had on local lizard populations. Some native Australian species, like frogs and snakes, have learned to avoid the toxic toads through trial and error, trying a few and deciding the food poisoning just wasn’t worth it....
A study published today in the Journal of Ecology seeks to solve a floral evolutionary mystery in China. The meadows of the Hengduan mountains in southwestern China are next to to the Qinghai-Tibet Plateau. Scientists consider the area to be a biodiversity hotspot, or an ecologically fragile place with unusually high numbers of different species. Here, dozens of species of closely-related plants appear to live in harmony. Rhododendrons are a genus of flowering shrubs that include bright purple and pink azaleas, the trumpet shaped elviira, and the blue peter....
When splotches of mold surfaced on Brandy Cabrera’s shower wall in September 2019, the 37-year-old bus attendant began to worry about her teenage son, who is autistic. “He has got to breathe in all that mold while he is taking a bath,” Cabrera says, referring to his longstanding morning routine. To fix the leak causing the mold, Cabrera followed protocol, contacting the New York City Housing Authority (NYCHA), which owns the Red Hook Houses, the public housing complex in Brooklyn where she has lived for the past 13 years....
There may be times where your house smells funkier than you’d like. And while there’s nothing particularly wrong with your walls smelling like day-old pizza, scientists say that prolonged exposure to stink can result in a slew of physical manifestations, like headache or nausea. It’s also been found that malodors can also have adverse psychological, physical, social, and even economic effects. The responsible—and healthy—way to tackle indoor odors is to stop the funk permanently....
