420 Million Years Ago, Oxygen Depletion Caused A Mass Extinction That Out Wiped 23 Percent Of All Marine Animals
Late in the prehistoric Silurian Period, around 420 million years ago, a devastating mass extinction event wiped 23 percent of all marine animals from the face of the planet.
For years, scientists struggled to connect a mechanism to this mass extinction, one of the 10 most dramatic ever recorded in Earth's history. Now, researchers have confirmed that this event, referred to by scientists as the Lau/Kozlowskii extinction, was triggered by an all-too-familiar culprit: rapid and widespread depletion of oxygen in the global oceans.
Trump's Executive Order Was Needed - 76% Of Kidney Transplant Candidates Receive At Least One Offer But Never Know It
Candidates who died without a transplant received a median of 16 offers (over 651 days) while waitlisted.
And most patients were never made aware they got an offer at all.
CDC, FDA Sound Alarm About Vaping, But With Millions More People Using Them Illnesses Are Still Just 25% of Raw Milk
Sure. I am all for smoking cessation and harm reduction products, but e-cigarettes are a device and a device can have lots of things put in it, including marijuana or whatever people might use. THC vape oil and cannabis vaping products are really sketchy, so obviously the issue may not be the e-cigarettes themselves, it may be bogus contaminants supplement hucksters are including.
But the devices will be the common denominator.
The Paris-based International Astronomy Union (IAU) is not really astronomy’s official governing body any more than NASA is. They often claim to be but they are a few hundred astronomers. They do not determine official designations any more than a few scholars with expert in CRISPR at a National Academy can tell FDA to stop treating harmless gene editing in plant varietals as a new drug in the regulatory scheme.
Pluto was demoted by a vote of 237 people, not the science community.
Experts say the remain found from between the 13th and 15th centuries in the Pampa La Cruz sector of the Huanchaco beach area over 300 miles north of Lima, make it the world’s largest child sacrifice site.
The evidence was clear; if you took a compass and drew a circle around a Whole Foods store, you were going to find anti-vaccine beliefs, organic food, and insistence that solar power would keep the lights running. And Whole Foods stores were only in wealthy areas, 80 percent of whom had voted for President Obama.
Celebrities and environmentalist jetting off to exotic locations to talk about climate change, renewable energy, and organic food may make you feel like the modern world is killing the planet but a huge collaborative study reveals that early humans across the entire globe were ruining their environments as far back as 10,000 years ago.
Farther back, 12,000 years ago, humans were mainly foraging, meaning they didn't interact with their environments as farmers do. By 3,000 years ago, farmers were feeding nations and causing free trade in many parts of the globe.
Instead of being ground in evidence, the plant-based and vegan diet fads could worsen an already low intake of an essential nutrient involved in brain health. And governments which spend time creating panic about salt and sugar fail to monitor dietary levels of this vital nutrient--choline--found predominantly in meat and eggs.
Before Clovis? The Original Native Americans May Have Arrived 1,000 Years Before Previously Believed
Artifacts from an archaeological dig at the Cooper's Ferry site located along the Salmon River, a tributary of the larger Columbia River basin in western Idaho, suggest that the original native Americans were here 1,000 years earlier than previously thought, about 16,000 years ago.
The findings add weight to the hypothesis that initial human migration to the Americas followed a Pacific coastal route rather than through the opening of an inland ice-free corridor. The belief is that timing and position of the Cooper's Ferry site, located at the confluence of Rock Creek and the lower Salmon River, is consistent with and most easily explained as the result of an early Pacific coastal migration.
Neither extreme turned out to be valid and a new study affirms what scientists have long said; there is no "gay" gene. The genome-wide association in Science used 477,522 people, 26,827 reported same-sex sexual behavior. Even when all tested genetic variants were taken into account, they collectively accounted for no more than a quarter of the same-sex behavior reported by the study participants.
Significant global landcover change had occurred by then, so if a new epoch really did start, it was not in the 20th century, finds a new study by a large international team of archaeologists and environmental scientists behind the ArchaeoGLOBE project.
This is an example to show how utterly unreliable the Daily Express is. This is me according to the Daily Express. End of world: Scientist’s terrifying warning of apocalypse asteroid - ‘Would boil oceans!’ It is nonsense! Unlike most of the people they misquote or quote out of context, I can write blog posts for Science 2.0 and most of my posts go to the top of Google News for a while. So I am writing this in the hope that some of you scared of this story will find this post and also our group.
Northwestern University computer scientists say they can prove that WhatsApp use played a key role in the electoral process. Their analysis shows that the Brazilian right in 2018 did what the American left did in 2008; they used social media to beat their opponents in a way that left them baffled.
The Most Volcanically Active Body In Our Solar System Is Not Earth, It's Jupiter's Moon Io. But Elsewhere...
The possible exomoon would orbit a hot giant planet, which in turn would race once around its host star in less than three days.
Theoretically, large amounts of sodium at an exoplanet could point to a hidden moon or ring of material, and ten years ago, researchers at Virginia calculated that such a compact system of three bodies: star, close-in giant planet and moon, can be stable over billions of years.
Pain Patients Are Not The Problem, Shows CDC, Opiod Deaths Are Due To Recreational Fentanyl Plus Benzos, Cocaine, And Meth
Attorneys will claim it, they will get thousands of people to sign up as litigants, and juries will agree with the emotional arguments they hear, but that has nothing to do with science or health. In appeals cases, science data is used, which is why so many spectacularly ridiculous judgments (like baby powder or a weedkiller magically causing cancer) get overturned.
The Northern White Rhino Is Not Going Extinct, It Isn't A Species And There Are 20,000 Of The Species Left
Called by some the square-lipped rhinoceros due to their square upper lip, they have a longer skull than black rhinos and a larger shoulder hump. They have two horns.
There are over 20,000 of them left, a big conservation win, but if you read environmental accounts they are going extinct, only two remain.
How can there be 20,000 of a species and yet only two?
If you are a believer in the precautionary principle over all, you buy armloads of organic food at the farmer's market on Saturday, ingest herbs and supplements to promote probiotic health, and religiously obey expiration dates, your refrigerator is probably where food goes to die.
How accurate that is beyond the last 30 years is unclear.
