National Guard officer to say he saw 'excessive' force used on protesters near the White House

  National Guard officer to say he saw 'excessive' force used on protesters near the White House Major Adam DeMarco will be before a House committee and will say the actions against peaceful protesters in Lafayette Square were 'deeply disturbing.'Major Adam DeMarco, who served as a liaison between the D.C. National Guard and the Park Police at Lafayette Square, plans to tell lawmakers the disproportionate use of force he witnessed against largely peaceful protesters was "deeply disturbing" to him and other Guardsman.

The winners of the 2020 Ig Nobel Prizes have been announced, and the honored experiments include frozen knives made from poop, an alligator forced to inhale helium, and vibrating earthworms. This annual contest highlights achievements that make “people laugh, then think.”

The 30th Ig Nobel Prize ceremony was held online this year due to covid-19. Normally, these prizes, awarded by the satirical humor magazine Annals of Improbable Research, are handed out at a live event held at Harvard University. Global pandemic or not, the 2020 Ig Nobels still managed to celebrate the quirkier side of scientific research.

Trump's controversial Pentagon No. 3 Anthony Tata is eligible to become acting Defense Secretary

  Trump's controversial Pentagon No. 3 Anthony Tata is eligible to become acting Defense Secretary President Trump's controversial pick for a top Pentagon post is eligible to be named Defense Secretary.Retired Army Brig. Gen. Anthony Tata, who once branded former President Obama a "terrorist leader" in a tweet, pulled his name from consideration for undersecretary for policy on Sunday. After Tata withdrew, he was promptly installed at the Pentagon "as the official performing the duties of the deputy undersecretary of Defense for policy," according to a Pentagon statement.

Experimental archaeologist Metin Eren and his colleagues from Kent State University were awarded the Materials Science Prize for manufacturing knives made from frozen poop.

The experiment was prompted by an ethnographic account of an Inuit man in Canada who claimed to have fashioned a knife made from his own feces. Eren’s team at the university’s Experimental Archaeology Lab decided to put this claim to the test, so they manufactured their own frozen poop knives—which they did using poop supplied by team members, Eren included. Unshockingly, the poopy knives didn’t work (the knife-edge blade “quickly melted and deteriorated,” according to the research), casting the ethnographic account into doubt.

Speaking to me by phone, Eren said he was “pretty excited” about winning the award. That his team might win an Ig Nobel prize crossed his mind during the frozen poop experiment, he admitted. Back in 2003, he and sister actually attended the Ig Nobel award ceremony at Harvard University.

Donald Trump seems to think he has already won the Nobel Peace Prize

Trump is heading to Ohio for campaign rallies. Here it is: "I said let's turn on the evening news. Let's watch it. This is gonna be a big show tonight. Get ready. And NBC, which is one of the most crooked, one of the worst newscasts.

“We knew this was a possibility,” said Eren. “We were very conscious of that fact.”

The Ig Nobels are “really important,” he added, because, in addition to promoting critical thinking, they “illustrate an important tool that humans have to do good and cause societal change—that tool being humor,” he said. The Ig Nobels provide a nice relief from outrage, another useful tool, said Eren.

Eren described the poop research as a “humorous rallying cry for demonstrating the importance of evidence and fact checking,” which he said is increasingly critical in this day and age.

As a fun aside, I actually got a chance to hold these poop blades. Last year, Gizmodo, along with Atlas Obscura, produced a video about Kent State’s Experimental Archaeology Lab, which includes a short clip about the frozen poop knives.

The Experimental Future of Digging Up the Past

Another winner was a paper co-authored by Stephan Reber from the University of Vienna, granted the Acoustics Prize. The team placed an alligator into a helium-filled chamber to study potential changes in its ability to produce sounds. The point of this strange experiment was to determine if crocodilians and other reptiles can convey their size through their vocalizations. The helium affected the gator’s vocalizations in the expected way (higher pitch), but the authors aren’t sure if this actually communicates size to potential mates.

(Photo credit: BERIT ROALD/AFP/Getty Images) October 7-14, 2019 - The Nobel Prizes are announced. The Nobel Peace Prize is awarded to Ethiopian Prime Minister Abiy Ahmed for his role in ending the 20-year war between Ethiopia and Eritrea.

The Psychology Prize went to a group of American and Canadian researchers for developing a method to identify narcissists by looking at their eyebrows. A team led by Ivan Maksymov from the Swinburne University of Technology got the Physics Prize for vibrating earthworms at high frequencies to measure potential changes in their shapes.

Richard Vetter from the University of California, Riverside, won the Entomology Prize for showing that entomologists are actually afraid of spiders. I don’t know if that’s appropriate, ironic, or simply strange, given that entomologists study insects, which spiders are not. Vetter’s paper has a great title, though: “Arachnophobic Entomologists: When Two More Legs Makes a Big Difference.”

A very sarcastic Ig Nobel for Medical Education was granted to several world leaders, including U.S. president Donald Trump, Brazilian president Jair Bolsonaro, U.K. prime minister Boris Johnson, and Belarusian president Alexander Lukashenko, among others. They were given the award for “using the Covid-19 viral pandemic to teach the world that politicians can have a more immediate effect on life and death than scientists and doctors can.” Yikes.

These workers joined the farmers, who have been protesting for two weeks now against the new selling prices for fruit and vegetables. With our correspondent in Bangalore, Côme Bastin The State of Assam produces nearly 50% of India's tea, and it is found on many tables around the world.
