See video of the heaviest stick insect ever discovered in Australia
The remote rainforest in Far North Queensland, Australia, is home to spiders, deadly snakes and the newly found 15.75-inch-long stick insects.
Angus Emmott, a researcher and professor at James Cook University, helped identify the new Acrophylla alta species, Reuters reported. Emmott said the creature's large size could be an evolutionary response to its cool, wet habitat.

Emmott said in a July 31 news release that the insects' "body mass likely helps them survive the colder conditions, and that's why they've developed into this large insect over millions of years."
"From what we know to date, this is Australia's heaviest insect," Emmott said.
Emmott added that every species of stick insect has its own distinct egg style, including different textures, pittings, surfaces and even shapes.
Why did the insect previously go undiscovered?
Located in the Wet Tropics region of Far North Queensland, the insect stayed undiscovered for so long because of its remote habitat, Emmott said
"It's restricted to a small area of high-altitude rainforest, and it lives high in the canopy. So, unless you get a cyclone or a bird bringing one down, very few people get to see them," he added.
Two specimens of the Acrophylla alta were added to the Queensland Museum's collection to aid future research, according to Reuters.
"To conserve any ecosystem, we actually need to know what's there and what makes it tick before we can think about the best ways to conserve it," Emmott said.

Study attributes 440 'excess deaths' to January's Los Angeles wildfires
By Steve Gorman LOS ANGELES (Reuters) -Wildfires that devastated parts of the Los Angeles area in January indirectly led to hundreds of deaths in the ensuing weeks, far exceeding the official toll of 31 fatalities, according to a study released on Wednesday. The research, published in the Journal of the American Medical Association, or JAMA, estimated 440 "excess deaths" were attributable to the fires from January 5 to February 1, using models that compared predicted mortality under normal circumstances to actual numbers documented during that period. The additional deaths likely reflect a mix of factors, including increased exposure of people with heart and lung disease to poor air quality from smoke and toxins released by the fires, as well as healthcare delays and disruptions, the study said. The findings "underscore the need to complement direct fatalities estimates with alternative methods to quantify the additional mortality burden of wildfires and of climate-related emergencies more broadly," the researchers wrote. Two wind-driven wildfires that erupted during the first week of January on opposite sides of Los Angeles damaged or destroyed nearly 16,000 structures combined - laying waste to much of the seaside district of Pacific Palisades and the foothill community of Altadena. Together, the blazes scorched 59 square miles (152 sq km), an area larger than Paris. The official tally of people who perished as a direct result of the fires stands at 31, after the most recent set of human remains were unearthed in Altadena in July, six months after the fires. Governor Gavin Newsom in February requested nearly $40 billion in wildfire aid from Congress. Some estimates put economic losses from the fires at more than $250 billion, making the conflagration one of the most costly natural disasters in U.S. history. The JAMA study acknowledged some limitations, saying the data may need to be revised upward in the future and the research did not reflect any fire-attributable deaths beyond Feb. 1.

Three people evacuated from Antarctica base in high-risk rescue involving 24-hours of darkness, sub-zero temperatures
Three people were evacuated from a US research base in Antarctica during a high-risk operation in round-the-clock darkness and sub-zero temperatures, according to authorities. The Royal New Zealand Air Force conducted the perilous operation Tuesday afternoon after the United Nations Science Foundation requested a medical evaluation for three staff members at McMurdo Station, including one who needed urgent medical help, the RNZAF said in a statement Wednesday. 3 Three people were evacuated from a US research base in Antarctica during a high-risk operation in round-the-clock darkness and sub-zero temperatures. via REUTERS Advertisement A crew aboard the C-130J Hercules braved total darkness and bone-chilling temperatures to reach the station overnight, authorities said. Flights conducted in the continent's mid-winter season, which is between March and October, are often the most dangerous due to varying weather conditions and on-ice landings, Air Component Commander Air Commodore Andy Scott said. 'The crew can only attempt the flight after a detailed analysis of the weather and airfield state. The United States Antarctic Program Winter Team must physically create the runway before we can depart by ensuring the ice is groomed and suitable for landing,' Scott said in a statement.

AP Although the team determines if the flight and landing can be carried out safely, it can still be 'extremely challenging' to fly using night vision goggles, the commander added. 'This, coupled with there being no airfields available to divert to once the aircraft is past a certain point south, adds to the risk, so these missions are not taken lightly,' Scott said. A doctor was aboard the flight to provide medical assistance to the research staff, whose ailments were not immediately known, according to the RNZAF.

'This mission wasn't just difficult; it was one of the most technically demanding operations an aircrew can face. In extreme conditions, with little margin for error, the RNZAF executed this mid-winter Antarctic medevac flawlessly,' the embassy's Chargé d'Affaires, Melissa Sweeney, said in a statement.

RNZAF delivered, just as they always do,' Sweeney said.

Kennedy cuts funding for mRNA vaccine research. See how they work and why it matters.
The federal government is cutting $500 million in research money for development of mRNA vaccines, which were widely used against the COVID-19 virus. Health Secretary Robert F. Kennedy Jr. said in a statement Aug. 5 that the multimillion-dollar cuts are being made because 'the data show these vaccines fail to protect effectively against upper respiratory infections like COVID and flu.' Research that helped develop mRNA vaccines won the Nobel Prize in Physiology or Medicine in 2023. Members of the scientific community are criticizing Kennedy for his decision. How do mRNA vaccines work? Messenger RNA vaccines, or mRNA, differ from traditional ones. Instead of growing a virus and weakening it to allow the body to engage its natural defenses, mRNA vaccines use pieces of genetic code to manufacture a protein, a piece of the virus. That causes the body to create its own antibodies against the virus. Pharmaceutical companies Moderna and Pfizer-BioNTech created mRNA vaccines for COVID-19 during the coronavirus pandemic. This is how those vaccines worked: Can't see our graphics? Click here to reload the page. It can take years to develop and test traditional vaccines before they can be used. However, mRNA vaccines can be manufactured in just months, according to The New York Times. They can be rapidly restructured to combat viruses as they change. An mRNA vaccine does not interact with or affect our DNA, the CDC says. The body discards the mRNA after it's used. How do traditional vaccines work? The HHS unit Biomedical Advanced Research and Development Authority helps companies develop medical supplies to address public health threats and had provided billions of dollars for development of vaccines during the COVID-19 pandemic, Reuters reported. HHS said the cancellation includes a contract awarded to Moderna for the late-stage development of its bird flu vaccine for humans and the right to purchase the shots. The health agency said it was also rejecting or canceling multiple pre-award solicitations, including proposals from Pfizer, Sanofi Pasteur, CSL Seqirus, Gritstone and others, Reuters said. Kennedy is a longtime vaccine skeptic. He has called COVID-19 vaccines the deadliest ever made, and in June he fired 17 members of a CDC panel that made recommendations on vaccine use. It's unclear whether patients should be expecting COVID-19 vaccines this fall, USA TODAY reported CONTRIBUTING Adrianna Rodriguez and Ken Alltucker SOURCE USA TODAY Network reporting and research; Reuters; Centers for Disease Control and Prevention;
