In regions of the United States and Mexico that are prone to hurricanes, aggressive spiders are evolving to survive and ride out the storm.When hurricanes rage along the Gulf of Mexico or charge up the East Coast, they can reshape an entire habitat in a short time. The winds destroy trees and spread debris for miles, putting new pressure on the creatures living in these environments.But how do creatures adapt when their habitats are so disturbed? Researchers looked at Anelosimus studiosus spiders that live in storm-prone areas along the coast to see how they changed. Their study was published Monday in the journal Nature Ecology and Evolution.These weather systems are called "black swan events": a surprising event with a major impact that is explained with the benefit of hindsight. They don't offer much lead time, so the researchers had to scramble to study the spider colonies before and after projected storms.The team monitored Subtropical Storm Alberto and Hurricanes Florence and Michael during the 2018 hurricane season. They tried to anticipate the systems' trajectories and study areas that included 240 female spider colonies, comparing them with areas where spider colonies were unaffected by such storms.The researchers returned to the sites hit by the storms 48 hours later. About 75% of the colonies survived the initial storm strikes."It is tremendously important to understand the environmental impacts of these 'black swan' weather events on evolution and natural selection," said Jonathan Pruitt, lead study author, evolutionary biologist and Canada 150 Chair in McMaster University's Department of Psychology, Neuroscience & Behaviour. "As sea levels rise, the incidence of tropical storms will only increase. Now more than ever we need to contend with what the ecological and evolutionary impacts of these storms will be for non-human animals."The A. studiosis spider species has two main personality traits that are inherited: docile and aggressive.Aggressiveness can be determined based on their speed, attackers pursuing prey, cannibalizing male spiders as well as eggs and their vulnerability to the invasion of predatory spiders.On the one hand, aggressive colonies are better at gathering resources in times of scarcity. But when deprived of food or subjected to overheating, aggressive colonies can also suffer from infighting."Tropical cyclones likely impact both of these stressors by altering the numbers of flying prey and increasing sun exposure from a more open canopy layer," Pruitt said. "Aggressiveness is passed down through generations in these colonies, from parent to daughter, and is a major factor in their survival and ability to reproduce."The researchers determined that after a storm passed, the colonies that aggressively pursued food and resources were able to produce more egg cases. The spiderlings also had a better chance of surviving into early winter.In areas that weren't hit by storms, docile colonies thrived.These findings were consistent even as the storms varied in duration, intensity and size. The researchers believe this shows that extreme events can shape animal behaviors. They would like to conduct more long-term studies to learn whether this is the case. 3250

Inside the lab at Bambu Global, nearly two decades of work in chemistry is getting put to use in a new coronavirus test.“We focused very heavily over that duration of time, in developing a very strong patent portfolio that's really focused on color change technologies,” said Saleem Miyan, president of Bambu Global.Enter NowAware, a new test the company developed to detect the presence of coronavirus.It works like this: a sample of saliva or mucus is added to their test, which causes it to change color, indicating the virus is present. The company said it’s more than 90 percent accurate.“We engineered the molecules,” said Robb Osinski, CEO of Bambu Global. “The chemistry behind the molecules is such that when it's in the presence of the coronavirus, it will change the molecular structure of our chemistry, turning it from what is a colorless form, to a colored form and thereby indicating the presence of the virus itself.”It’s not fool-proof; it might also indicate the presence of other similar viruses like SARS or MERS. However, it’s fast, taking just a few minutes, at a time when coronavirus testing has been slow or unavailable.The company is now awaiting FDA-emergency approval and said once that comes through, they could begin production within two weeks. The company said the cost of the test would be around .“Our ultimate goal is providing total reassurance for people that they don't have the virus, they aren't carrying the virus and that ultimately, they can administer this very low-cost solution somewhere that's truly convenient for them,” Miyan said.It's something that they hope, one day in the future, might be right at home.“Ultimately, we envision this being a household product that you can literally test yourself and then know whether or not you're carrying the virus or a virus,” Osinski said.This, as the world deals with a pandemic, still in its early stages of outbreak. 1926

In a victory for Democrats in Virginia, the Supreme Court held Monday that the Republican-led Virginia House of Delegates did not have the legal right to challenge a lower court opinion that struck several district maps they had drawn as an unconstitutional racial gerrymander.This means court-ordered maps that favored Democrats will continue to be used.Justice Ruth Bader Ginsburg wrote the opinion for a 5-4 court, joined by Justices Clarence Thomas, Sonia Sotomayor, Elena Kagan and Neil Gorsuch.Because the Supreme Court dismissed the challenge on standing grounds, justices did not rule if the maps constitute an unconstitutional racial gerrymander."One House of its bicameral legislature cannot alone continue the litigation against the will of its partners in the legislative process," Ginsburg wrote."If the State had designated the House to represent its interests, and if the House had in fact carried out that mission, we would agree that the House could stand in for the State. Neither precondition, however, is met here. " 1048

LAS VEGAS — There's nothing like a puppy to brighten someone's day. And while a new furry best friend is a popular holiday gift, there's a word of caution about the hidden risk of getting a puppy from a pet store. Questions are being raised after the Humane Society released undercover video they shot at the Petland store near Summerlin, Nevada. The Humane Society had members of their organization get jobs there and at a store in Kennesaw, Georgia to document conditions they've been trying to expose for years. The video was shot in November at Petland in the Boca Park shopping center. The Humane Society claims the store is just waiting for the Maltese puppy in the video to die, and that people need to know the truth about those doggies in the window. "Since 2006, we received over 1,200 complaints from consumers who have purchased sick and sometimes dying puppies from Petland," says Humane Society Western Region Director Heather Carpenter. The animal welfare organization offers this video as proof that there's a problem when pets are sold for profit. But Boca Park Petland store owner Jeff Fausett says not so fast."My reaction is it's a total fabrication of the events," Fausett says.He says the Humane Society is trying to make it look like Petland was warehousing a dog until it died. "That's never happened here. That's not what we're about," he says. There are a few simple facts he wants to make clear."This was not a dog that, one, was in our kennel for weeks," Fausett says. "It was at the vet for weeks. It had a birth defect and it went back. It wasn't going to die."According to Fausett, after Petland sent the puppy out for medical care due to a respiratory infection, the veterinarian discovered the dog's air passage was too narrow. Fausett says he would never sell a puppy with that condition and surgery would cost several thousand dollars. So he sent the dog back to the breeder. "He re-homes those dogs when he gets them. He doesn't destroy them," Fausett explains. "So whether we re-home it or he re-homes, it is academic." 2085
