Astronomers from the California Institute of Technology and elsewhere report the detection of a new eclipsing detached double white dwarf binary. The system, designated ZTF J2243+5242 has an orbital period of below 10 minutes, which makes it one of the shortest-period eclipsing binaries known to date. The finding is detailed in a paper published October 7 on arXiv.org.


Astronomers are interested in finding and studying double white dwarfs (DWDs), as their mergers are believed to produce new white dwarfs with higher masses. It is assumed that some high-mass white dwarfs in the solar neighborhood could be DWD merger products.

The Zwicky Transient Facility (ZTF), using the Palomar Observatory in California, is one of the most important astronomical surveys to search for double white dwarf binary systems. So

Blue and White minister: We’ll depose Netanyahu if he goes to elections

Science and Technology Minister Izhar Shay has threatened that if Prime Minister Benjamin Netanyahu tries to go to new elections during the current crisis the Blue and White party will “ensure” that he does not remain in his position.The minister’s comments come as trust between Netanyahu’s Likud and its senior coalition partner Blue and White has sunk to new lows in recent days, amid a renewed fight over the state budget and political demonstrations.“The Likud is going to abuse the citizens; whoever goes to elections will pay the price,” said Shai on Channel 12’s Meet the Press program in reference to comments made by Likud MKs and coalition chairman Miki Zohar of late calling on the prime minister to break up the coalition.“The Likud made known this week through Miki Zohar that they will not work on the budget in order to dismantle the government,” said Shai.A state budget for

3,500-pound great white shark dubbed “Queen of the Ocean” spotted off North America’s coast

A 3,500 pound great white shark dubbed Nukumi — meaning “Queen of the Ocean” — has been spotted off the coast of Nova Scotia. The massive 50-year-old shark was tagged and released by Ocearch, a research and exploring team that hopes its latest trip out to sea provides new clues to unravel the mysteries of great whites.

“When you see these big females like that that have scars from decades over their lives and multiple mating cycles, you can really kinda see the story of their life unfolding across all the blotches and healed wounds on their body,” team leader Chris Fischer told CBS News’ Jeff Glor. “It really hits you differently thank you would think.”

The White House Announces Quantum.Gov and Quantum Frontiers Report

Oct. 7, 2020 — The White House Office of Science and Technology Policy (OSTP) has announced the launch of Quantum.gov, the official website of the National Quantum Coordination Office, and the release of the Quantum Frontiers Report identifying key areas for continued quantum information science (QIS) research.

“With the launch of Quantum.gov, the White House has created an online home for the National Quantum Coordination Office and a new digital hub for the growing quantum community to connect with wide-ranging activities underway across the Federal Government. The newly published Quantum Frontiers Report lays out critical research questions for the entire U.S. innovation ecosystem to tackle in the years ahead, and will serve as an important roadmap for researchers around the country,” said Michael Kratsios, U.S. Chief Technology Officer.

Quantum.gov will feature resources and news on QIS activities from across the Federal government, geared towards both the research community and the

The Science Femme Was Allegedly a White Male Professor Who Posed as Woman of Color and Bullied Women

“The Science Femme” claimed to be a female academic. She claimed to have upended efforts by her social justice-obsessed department to draft a statement condemning racism.

And when Twitter users accused her of racism, she claimed to be a woman of color herself—and an immigrant to boot.

But The Science Femme, who tweeted from the handle @piney_the, wasn’t any of those things, digital sleuths began alleging late last month. Instead, they claimed, “she” was Craig Chapman, a white male assistant professor of chemistry at the University of New Hampshire. The allegations, bolstered by an internal chemistry department email, would make Chapman at least the fourth white academic revealed to have posed as a person of color in recent weeks.

In three of those cases, academics are accused of shamelessly trying to further their own careers. But in Chapman’s case, Twitter users who came into contact with @piney_the say the account

Researchers find ‘Queen of the Ocean’ ancient great white shark off Nova Scotia coast

Researchers off the coast of Nova Scotia found a nearly 2-ton great white shark believed to be roughly 50 years old, dubbing her a true “Queen of the Ocean.”

Coming in at more than 17 feet long and 3,541 pounds, she is the largest shark the group has been able to sample in the Northwest Atlantic, according to a Friday Facebook post by OCEARCH, a non-profit marine research organization. She’s been named Nukumi for “the legendary wise old grandmother figure” of the Indigenous Mi’kmaq people, a First Nations group native to that region of Canada.

Chris Fischer, the OCEARCH expedition leader, called Nukumi a “proper Queen of the Ocean” in a video log posted Saturday.

“She’s probably 50-years-old and certainly her first litters of pups she would have been having 30 years ago are also making babies, really humbling to stand next to a large animal like that,” Fischer said.

Massive, 50-year-old great white shark dubbed ‘Queen of the Ocean’ caught and tagged

Scientists from OCEARCH, an NGO that is tagging and sampling white sharks, described the female shark as “Queen of the Ocean” and say they have called her Nukumi.

“We named her ‘Nukumi’, pronounced noo-goo-mee, for the legendary wise old grandmother figure of the Native American Mi’kmaq people,” Ocearch wrote in a Facebook post Saturday.

The Mi’kmaq culture has deep roots in Nova Scotia, according to the post.

“With the new data we’ve collected, this matriarch will share her #wisdom with us for years to come,” OCEARCH wrote.

Nukumi is the largest of eight great whites that researchers have sampled during the current expedition, which has been running for 27 days as of Monday.

OCEARCH also posted a video showing Nukumi lying on a special submersible platform built onto the side of its research vessel with researchers around her, and subsequently swimming away.

OCEARCH is an ocean data-collection organization that has

How Blue and White is both left and right

The party formed to represent the Israeli center has been going to extremes.On one side there are the loud voices from the Left side of the party, but there are voices on the Center-Right side as well.On the Center-Left, there is Tourism Minister Asaf Zamir, whose resignation takes effect on Monday; Science and Technology Minister Izhar Shay, who almost quit last week; and MKs Miki Haimovich and Ram Shefa, who voted against limits on political demonstrations in the Knesset.Haimovich made news on Sunday, when she said there is a group that is growing in Blue and White that is interested in breaking up the partnership with Likud. Other MKs talked about starting to vote more independently.But even if they are growing, they are still the minority in the party. The overwhelming majority of the MKs in the Blue and White-Derech Eretz-Labor bloc prefers staying the course and continuing the strategy

Opinion | The White House coronavirus outbreak shows that testing alone is not enough

But the castle walls were penetrated — presumably by an asymptomatic carrier, a covid-era Trojan horse — and infections among the president’s circle have cascaded out this week. The spotlight is on the Rose Garden reception for Supreme Court nominee Amy Coney Barrett, an event attended by nearly all of those who have recently tested positive: the president, first lady, senators, aides.

Per protocol, attendees were tested before they got near the president. But other defenses were down. According to The Post: “After guests tested negative that day they were instructed they no longer needed to cover their faces. The no-mask mantra applied indoors as well. Cabinet members, senators, Barrett family members and others mixed unencumbered at tightly packed, indoor receptions.” No masks, no distancing and time spent among crowds indoors are a recipe for transmission.

All of this underscores the central flaw in the White House’s approach: Testing alone

COVID in the White House: a drastic case of science trumping politics

One can only wish Donald Trump (and first lady Melania Trump) a full recovery from COVID-19. In the meantime, the president’s illness could save many lives. To date, his focus has been on manipulating the truth about how this deadly disease is prevented — through wearing masks and social distancing — so as to minimize its effect on his reelection bid. Ironically, his illness exposes his lies to the surprisingly large minority of the population who believed him. Let’s hope they don’t continue to go maskless in public and thus follow Trump to the edge of the COVID-19 precipice.

May the president’s and first lady’s illness be a wake-up call to our country that when it comes to our nation’s health, science trumps politics.
