Dinosaurs would have kept right on living, had an asteroid not wiped them out. That’s according to new research from the University of Bath and London’s Natural History Museum.
While it’s recently been en vogue to claim that dinosaurs were seeing their time of planet-wide domination come to an end even before a massive impact hurried them off the Earth, this new study claims that dinosaurs would have lived on.
The theory this study refutes claims that dinosaur species diversity was dwindling, a sign that the entire branch of the animal kingdom was winding down while avians and mammals were on the rise.
“What we found is that the dinosaurs were still dominant, they were still widespread and still doing really well,” explained lead author Joe Bonsor. “If the asteroid impact had never happened then they might not have died out and they would have continued after the Cretaceous.’
Bonsor and his fellow researchers believe that the prior theory is based on gaps in the fossil record and not hard evidence. Dinosaurs were an incredibly diverse group of animals that lived for hundreds of millions of years. While many of them died in that time, most of their remains were not fossilized. Bonsor thinks that the theory of diversity decline is based on lack of fossils and not proof.
He said: “Previous studies done by others have used various methods to draw the conclusion that dinosaurs would have died out anyway, as they were in decline towards the end of the Cretaceous period.
“However, we show that if you expand the dataset to include more recent dinosaur family trees and a broader set of dinosaur types, the results don’t actually all point to this conclusion – in fact only about half of them do.”
World Mental Health Day, observed on 10 October, is an opportunity to raise awareness of mental health issues and to mobilize efforts in support of mental health. This year, the theme is suicide prevention.
Scientists at North-Eastern Federal University (NEFU) in Yakutsk, Russia, on Monday announced a finding of “great importance” — a preserved Ice Age cave bear carcass, estimated to be to be between 22,000 and 39,500 years old.
The preserved bear was found by reindeer herders on Bolshoy Lyakhovsky Island, part of the Lyakhovsky Islands archipelago in northern Russia, according to a statement from NEFU.
“Today this is the first and only find of its kind — a whole bear carcass with soft tissues,” scientist Lena Grigorieva said in a statement. “It is completely preserved, with all internal organs in place.
North Korea fired gunshots at the wall of a South Korean guard post in the Demilitarized Zone (DMZ), a buffer area which separates the two countries, on Sunday,
The South Korean military responded by broadcasting a verbal warning and returning fire twice, according to protocol outlined in the response manual and on the judgment of the field commander, according to the JCS statement.
The South Korean military said that “the military is in the process of identifying situations over the military communication line with the North and preventing any additional situations from occurring.”
Under the military accord signed between the two Koreas on September 29, 2018, the South and North each demolished 11 guard posts along the DMZ, but dozens of guard posts remain.
There have been exchanges of fire between the Koreas in the past, including in 2017, when a North Korean solider defected at the JSA (Joint Security Area) and, in 2014, when a North Korean defector organization launched balloons of leaflets criticizing the country’s reclusive regime.
It is not known what caused this exchange of fire.
The tiny fossil is unassuming, as dinosaur remains go. It is not as big as an Apatosaurus femur or as impressive as a Tyrannosaurus jaw. The object is a just a scant shard of cartilagefrom the skull of a baby hadrosaur called Hypacrosaurus that perished more than 70 million years ago. But it may contain something never before seen from the depths of the Mesozoic era: degraded remnants of dinosaur DNA.
Genetic material is not supposed to last over such time periods—not by a long shot. DNA begins to decay at death. Findings from a 2012 study on moa bones show an organism’s genetic material deteriorates at such a rate that it halves itself every 521 years. This speed would mean paleontologists can only hope to recover recognizable DNA sequences from creatures that lived and died within the past 6.8 million years—far short of even the last nonavian dinosaurs.
But then there is the Hypacrosaurus cartilage. In a study published earlier this year, Chinese Academy of Sciences paleontologist Alida Bailleul and her colleagues proposed that in that fossil, they had found not only evidence of original proteins and cartilage-creating cells but a chemical signature consistent with DNA.
A Geneva Bible dating to 1615 that was stolen from a Pennsylvania library has been found in the Netherlands and returned to the US, authorities announced at a Thursday news conference.
The Bible, which has survived more than four centuries, was one of more than 300 items allegedly stolen from the Carnegie Library of Pittsburgh as part of a 20-year scheme by a former archivist Gregory Priore, 62, and rare books dealer John Schulman, 54, local outlet KDKA reports, both of whom had long worked closely with the library. They have been charged with theft, conspiracy and forgery, among other counts.
Investigators traced the tome to the American Pilgrim Museum in Leiden, which had paid about $1,200 for it. Allegheny County District Attorney Stephen Zappala explained that the director of the Leiden museum realized the Bible it had purchased belonged to the Carnegie Library and reached out to the institution. He’s “an honest man,” Zappala said, according to KDKA.
There are 695 cases in 22 states. HHS Secretary Alex Azar said the spike was “avoidable” and he called measles vaccines “among the most extensively studied medical products we have.”
The agency attributed the high number of cases primarily to a few large outbreaks — one in the state of Washington and two others in New York City and New York state. The New York outbreaks are among the largest and longest lasting since 2000.
“The longer these outbreaks continue, the greater the chance measles will again get a sustained foothold in the United States,” the CDC said.
Health and Human Services Secretary Alex Azar said, in a statement, said the rise in measles cases is “avoidable.”
“Measles is not a harmless childhood illness, but a highly contagious, potentially life-threatening disease,” he said. “We have the ability to safely protect our children and our communities. Vaccines are a safe, highly effective public health solution that can prevent this disease. The measles vaccines are among the most extensively studied medical products we have, and their safety has been firmly established over many years in some of the largest vaccine studies ever undertaken.”
Survey of U.S. adults found “critical gaps both in awareness of basic facts as well as detailed knowledge of the Holocaust”
NEW YORK — More than one-fifth of millennials in the U.S. — 22 percent — haven’t heard of, or aren’t sure if they’ve heard of, the Holocaust, according to a study published Thursday, on Israel’s Holocaust Remembrance Day. The study, which was commissioned by The Conference on Jewish Material Claims Against Germany and conducted by Schoen Consulting, also found that 11 percent of U.S. adults overall haven’t heard of the Holocaust or aren’t sure if they did.
Additionally, 41 percent of millennials believe two million Jews or fewer were killed during the Holocaust, the study found. Six million Jews were killed in World War II by Nazi Germany and its accomplices.
Two-thirds of millennials could not identify in the survey what Auschwitz was.
“The survey found there are critical gaps both in awareness of basic facts as well as detailed knowledge of the Holocaust,” said a news release on the findings.
On April 4, 1968, Walter Cronkite, then-anchor of the “CBS Evening News,” went on air with a detailed report on the shooting and the nation’s reaction to the tragedy
The Rev. Martin Luther King Jr. was standing on the balcony of the old Lorraine Motel in Memphis, Tennessee, when he was shot dead 50 years ago today. King, an iconic pastor who led non-violent protests against racial inequality in the civil rights movement, later died at a hospital. He was 39.
That night, Walter Cronkite — then-anchor of the “CBS Evening News” — went on air with a detailed report on the shooting and the nation’s reaction to the tragedy.
The April 4, 1968 broadcast
“Dr. Martin Luther King, the apostle of non-violence in the civil rights movement, has been shot to death in Memphis, Tennessee,” Cronkite said. “Police have issued an all-points bulletin for a well-dressed, young white man seen running from the scene. Officers also reportedly chased and fired on a radio-equipped car containing two white men.”
“Dr. King was standing on the balcony of a second-floor hotel room tonight when, according to a companion, a shot was fired from across the street. In the friend’s words, the bullet exploded in his face,” Cronkite reported.
Hundreds of schools were closed Monday morning in Oklahoma and Kentucky while thousands of teachers rallied at their state capitols, CBS News correspondent Omar Villafranca reports. They’re demanding higher pay and increased school funding.
Art teacher Laurissa Kovacs says her kids aren’t even getting the basics at Puterbaugh Middle School.
“The chairs are in awful condition,” Kovacs told Villafranca. “They’re broken and they literally hurt the kids to sit down. If you look through the stacks, you can just see how many of the broken areas and cracks that will pinch you and jagged tops.”
Kovacs says she’s had to bring in folding chairs from home to give her students a proper place to sit. She can’t take the frustration any longer.
A battle to take down a statue of President William McKinley in the small Northern California city of Arcata reflects a growing debate around the country on monuments that honor those who helped bring about the deaths of Native peoples.
No other city has taken down a monument to a president for his misdeeds. But Arcata is poised to do just that. The target is an 8½-foot bronze likeness of William McKinley, who was president at the turn of the last century and stands accused of directing the slaughter of Native peoples in the U.S. and abroad.
