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

Double jeopardy for ecologically rare birds and terrestrial mammals

Common assumptions notwithstanding, rare species can play unique and essential ecological roles. After studying two databases that together cover all known terrestrial mammals and birds worldwide, scientists from the CNRS, the Foundation for Biodiversity Research (FRB), Université Grenoble Alpes, and the University of Montpellier have demonstrated that, though these species are found on all continents, they are more threatened by human pressures than ecologically common species and will also be more impacted by future climate change. Thus, they are in double jeopardy. The researchers’ findings, published in Nature Communications (October 8, 2020), show that conservation programs must account for the ecological rarity of species.


It has long been thought that rare species contribute little to the functioning of ecosystems. Yet recent studies have discredited that idea: Rarity is a matter not only of the abundance or geographical range of a species, but also of the distinctiveness

Common assumptions notwithstanding, rare species can play unique and essential ecological roles. After studying two databases that together cover all known terrestrial mammals and birds worldwide, scientists from the CNRS, the Foundation for Biodiversity Research (FRB), Université Grenoble Alpes, and the University of Montpellier[1] have demonstrated that, though these species are found on all continents, they are more threatened by human pressures than ecologically common species and will also be more impacted by future climate change. Thus they are in double jeopardy. The researchers’ findings, published in Nature Communications (October 8, 2020), show that conservation programmes must account for the ecological rarity of species.

Microsoft is being questioned by the US government over whether a diversity initiative amounts to racial discrimination.

The Department of Labor has singled out the firm’s pledge to double the number of “black and African American” senior staff by 2025.

Officials have warned the company the target appears “to imply that the employment action may be taken on the basis of race”.

Microsoft denies the accusation.

“We are clear that the law prohibits us from discriminating on the basis of race,” the firm’s lawyer Dev Stahlkopf blogged.

“We also have affirmative obligations as a company that serves the federal government to continue to increase the diversity of our workforce, and we take those obligations very seriously.

“One thing remains true of all our programmes. We hire and promote the most-qualified person. And nothing we announced

New Research From Accenture and Girls Who Code Outlines Steps to Double the Number of Women in Technology in 10 Years

Joint report reveals just eight percent of women of color say it’s easy to thrive in technology

An inclusive culture is key to unlocking opportunities for women who are studying and working in technology, and holds the potential to double their number over the next 10 years, according to a joint research report by Accenture (NYSE: ACN) and Girls Who Code, an international nonprofit working to close the gender gap in technology.

Radiation levels on moon more than double those on space station

Sept. 25 (UPI) — Radiation levels on the surface of the moon are 2.6 times greater than those measured on the International Space Station, according to a new study.

NASA intends to put the first woman on the moon by 2024 — and the first man since 1972. Earlier this week, the space agency released new details about its Artemis program, including its decision to target a landing spot on the lunar South Pole near Shackleton Crater.

Regardless of where NASA’s lunar landers touch down, Artemis astronauts will need to protect themselves from increased radiation levels.

Using the Lunar Lander Neutron and Dosimetry, or LND, scientists were able to, for the first time, measure radiation levels on the lunar surface.

Scientists shared the first-of-their-kind measurements in a new paper, published Friday in the journal Science Advances.

“The radiation exposure we have measured is a good benchmark for the radiation within
