It hit the planet about 3.26 billion years ago and is estimated to have been up to 200 times larger than the space rock that later killed the dinosaurs. The new findings, published in the scientific journal Proceedings of the National Academy of Sciences on Monday, suggest that this massive collision not only brought destruction to Earth, but also helped early life thrive. The research has been a passion project for Drabon, who was inspired by numerous previous studies that showed the potential impact a meteorite collision can have on life forms. “We have long known that on the young Earth meteorite impacts were both more frequent and, on average, larger than today,” said Andrew Knoll, a Harvard geologist and study co-author. “While people have speculated about the potential biological and environmental consequences of ancient impacts, there has been little hard data to test varying hypotheses,” Knoll added.

CHICAGO — The CDC is deploying a team to Washington state to assess the health of farm workers who culled poultry suffering from bird flu after four workers are presumed to have been infected by the virus, U.S. and state health officials said on Monday. The cases fuel growing concern among public health experts, as infections of U.S. dairy cattle and more than two dozen farm workers have worried scientists and federal officials about the risks to humans. California and Washington have said they are seeking to administer seasonal flu vaccines to farm workers to reduce their risk of being infected with both bird flu and seasonal influenza. “We don’t have evidence yet of transmission between people,” said Roberto Bonaccorso, spokesperson for the Washington State Department of Health. The Centers for Disease Control and Prevention is awaiting specimens for testing from Washington and sending a team to support the state’s assessment of farm workers, an agency spokesperson said.

Spherules can be seen in this sample taken from another meteorite impact. Then all of a sudden, you have a giant tsunami, sweeping by and ripping up the seafloor.”This graphic shows the sequence of events following the S2 giant meteorite impact. When oceans boil and evaporate, they form salts such as those observed in the rocks directly after the impact, Drabon said. The researchers studied layers in this rock and determined that a global tsunami was initiated by the S2 meteorite impact 3.26 billion years ago. “Life during the time of the S2 impact was much simpler,” she said.

CNN —When scientists heard reports that a large, mysterious fish had been caught in Cambodia in 2020, excitement stirred. Could this be the “Mekong Ghost,” they asked - an elusive fish that hadn’t been seen since 2005 and was feared extinct? But the fish, which can grow as large as 66 pounds, was sold before scientists could get a closer look. The giant salmon carp has been rediscovered in Cambodia. Chhut Chheana/Wonders of the Mekong“I’ve been looking for it since then, kind of fascinated by it because it’s a very unusual giant fish,” Hogan said.

CNN —A mile and a half beneath the ocean’s surface, the seafloor seems nearly as alien as the surfaces of other planets. These hydrothermal vents belch warm towers of elements that draw clusters of animal life, such as tube worms. There, animals develop symbiotic relationships with bacteria that use chemical reactions to produce sugars necessary for life beyond the reach of sunlight. Mónika Naranjo-Shepherd/Schmidt Ocean InstitueThe arms of an underwater robot helped uncover communities of giant tube worms and snails living in volcanic caves beneath warm vents in the Pacific Ocean. The finding suggests unique ecosystems on the seafloor and within the subseafloor are connected, allowing life to thrive above and below the ocean bed.

CNN —The origin of modern humans’ long-standing love affair with carbs may predate our existence as a species, according to a new study. The study revealed these genes duplicated long before the advent of agriculture. Without amylase, humans would not be able to digest foods such as potatoes, pasta, rice or bread. The research also revealed duplication of the AMY1 gene existed in the genomes of Neanderthals and Denisovans, an extinct hominin first discovered in 2010 about whom relatively little is known. “This study’s genomic sleuthing is helping to finally time stamp some of those major milestones, and it is revealing tantalizing clues about humanity’s long love affair with starch.”

The previous record from the 2014 to 2017 mass bleaching affected just below 66% of the world’s reef area. Triggered by heat stress in warm oceans, coral bleaching occurs when corals expel the colourful algae living in their tissues. A bleached coral is not dead, but ocean temperatures need to cool off for any hope of recovery. “We’ve never had a coral bleaching event this big before.”In just the last six weeks, bleaching has been confirmed in the waters of Palau, Guam and Israel. What are we going to do about it?” said Emily Darling, who leads the Wildlife Conservation Society’s global coral reef conservation programme.

In a quest to find the first complete head, researchers conducted an analysis of Arthropleura fossils belonging to two juvenile individuals uncovered in the 1970s in France. Researchers studied scans of two Arthropleura fossils trapped in stone. Both fossilized insects still had most of their legs, and one of them had a complete head, including antennae, eyes, mandibles and its feeding apparatus — the first Arthropleura head ever documented, Lhéritier said. Researchers believe the two Arthropleura fossils belonged to juveniles because they reach just 0.9 inch (25 millimeters) and 1.5 inches (40 millimeters) long. But other fossils that preserve additional aspects of the arthropod’s body, including the head of an adult, will need to be found.

Phoenix on Tuesday snapped a streak of 21 straight days of record-breaking highs. Heat waves are expected to start earlier in the year and last later as a result of climate change, but Phoenix's streak still surprised scientists. The heat is finally expected to break heading into the weekend, as a cold front brings cooler conditions. The city on Tuesday finally snapped a streak of 21 straight days of record-breaking daily high temperatures. This summer was already the hottest on record in Phoenix, and 2024 is likely to end up as the warmest year in the city's recorded history.

The Summary New research offers insight into the evolutionary history of amylase genes, which are key to our ability to eat and digest starchy food. Amylase genes produce an enzyme in saliva and the gut that’s key to breaking down starches into sugar. New research published Thursday in the journal Science suggests the amylase gene has a much longer evolutionary history than scientists previously thought. Some studies have suggested that populations with higher numbers of amylase copies tend to eat more starch, though more research is needed to explore those theories. … There are things that just exist.”Both recent studies relied on a relatively new technology to analyze genetic material from ancient humans.

Texas is preparing to put a man to death Thursday in what would be the nation’s first execution involving a case of “shaken baby syndrome,” a diagnosis that has been re-evaluated in more recent years, leading to the overturning of similar convictions. Prosecutors argued that Nikki must have been shaken to death because she had been diagnosed with “the triad” — a swollen and bleeding brain and retinal hemorrhaging — symptoms once believed to be indisputable evidence of shaken baby syndrome. In 2009, the American Academy of Pediatrics changed the name of shaken baby syndrome to the more broadly defined “abusive head trauma” to include injuries caused by mechanisms other than shaking alone. It is now medical consensus that other medical conditions, including infections, accidental trauma and pre-existing illnesses, can also cause the symptoms associated with shaken baby syndrome. Hundreds of possible shaken baby and abusive head trauma cases are reported to hospitals in the U.S. every year, according to a nonprofit advocacy group.

CNN —A Travis County judge granted a Texas House committee’s last-minute temporary restraining order request against the state just 90 minutes before Robert Roberson was scheduled to be executed Thursday. While authorities have not confirmed the execution is delayed, Roberson’s attorneys and the committee fighting for him told CNN they believe the execution is currently halted. “This is an injustice and his blood is on Abbott and Anderson County,” she told CNN. I did not hear his voice,” Brian Wharton, the former detective who oversaw the investigation into Nikki’s death, told state lawmakers Wednesday at a hearing featuring the case. I don’t want to be there, I don’t want to watch it happen,” Wharton told CNN.

US efforts to produce semiconductor chips will continue regardless of who wins the election. AdvertisementNo matter who wins the presidential election this November, President Joe Biden can rest easy knowing one thing: The US's chip manufacturing push isn't going anywhere. The US has seen its share of overall chip production fall from 37% of the world's supply in 1990 to 12%. While many factories remain under construction, the federal funding has already helped boost US chip production. According to a report published last year by the trade and lobbying group Semiconductor Industry Association and Oxford Economics, the US semiconductor industry will face a shortage of 67,000 workers by 2030, including technicians, computer scientists, and engineers.

CNN —For the first time, scientists have found evidence that marine mammals could be inhaling microplastics, according to new research that detected the potentially harmful particles in the breath of bottlenose dolphins off the coasts of Louisiana and Florida. Previous research has discovered the tiny particles present in marine mammals’ tissues from exposure through consumption and then movement from the digestive tract into other organs. “We found that dolphins may be breathing in microplastics, even if they live in rural areas away from high levels of human activity. The researchers are unsure how inhalation of microplastics will affect dolphins, but they suspect it could have an impact on the creatures’ lung health, according to the study. The study team held up petri dishes to the mammals’ blowhole, through which dolphins inhale and exhale.

One of the National Football League's toughest competitions doesn't take place anywhere near a football field. For the seventh year in a row, data scientists and analytics buffs will be invited to test their mettle against each other in the league's Big Data Bowl, powered by Amazon Web Services. The competition's goal is to distill the copious amounts of data collected from every player during every NFL game into stats and insights that the league and its teams can learn from. The Big Data Bowl was first introduced by the NFL in 2018 and quickly became a fertile proving ground for teams to find bright minds to add to their front offices. This year's competition challenges participants to use data collected before the ball is snapped to help predict what an offense or defense is going to do during a given play.

London CNN —For consumers still scarred by jumps in their energy bills in recent years, the International Energy Agency has good news: Oil and natural gas prices will probably be lower over the next five years. Energy prices soared in the wake of Russia’s full-scale invasion of Ukraine in February 2022, which followed a rise in global demand as economies reopened after Covid lockdowns put lives on hold. And that “would move us into a very different energy world from the one we have experienced in recent years during the global energy crisis,” he added in a statement accompanying the IEA’s latest World Energy Outlook report. But global oil output has been increasing, thanks mostly to producers in the United States and other countries in the Americas. The energy body reiterated its previous forecasts that demand for oil, natural gas and coal will peak by the end of the decade.
