MoonRanger, a small robotic rover being developed by Carnegie Mellon University and its spinoff Astrobotic, has completed its preliminary design review in preparation for a 2022 mission to search for signs of water at the moon’s south pole.


Whether buried ice exists in useful amounts is one of the most pressing questions in lunar exploration, and MoonRanger will be the first to seek evidence of it on the ground. If found in sufficient concentration at accessible locations, ice might be the most valuable resource in the solar system, said William “Red” Whittaker, University Founders Research Professor in the Robotics Institute.

“Water is key to human presence on and use of the moon,” explained Whittaker, who is leading development

Wreck of 17th-Century Danish Warship Found in the Baltic Sea | Smart News

Marine archaeologists have located the wreck of a Danish warship defeated at sea approximately 376 years ago, reports the German Press Agency (DPA).

Per a statement from the Viking Ship Museum in Roskilde, the Delmenhorst sank during the Battle of Fehmarn, an October 1644 maritime clash between Christian IV’s Danish forces and a joint Swedish-Dutch fleet.

Researchers using multibeam sonar spotted the Delmenhorst’s remains while surveying the Fehmarn Belt, a strait in the western part of the Baltic Sea, ahead of construction of a planned underwater tunnel connecting northern Germany to the Danish island of Lolland. The wreck had come to rest just 500 feet from Lolland’s southern shore, at a depth of some 11.5 feet.

Space junk even worse than what we can see, astronomers say

Tracking space junk

Orbital debris, not functional satellites, make up 95 percent of the objects in this computer-generated illustration of objects in low-Earth orbit.

The debris and detritus orbiting above our heads has been multiplying as humans send more and more satellites and rockets into space. All that space junk can pose a threat to operating satellites, and new research suggests that the problem could be much worse than previously thought. 

Astronomers at the University of Warwick attempted to cross-reference detected orbital debris in geosychronous orbit — the altitude where many large communications satellites circle our planet — with objects in public satellite catalogs. They found that more than 75 percent of the debris did not have a match. 

Most of the unknown objects were faint and small, measuring 39 inches (one meter) or less.

This Priestess Is Teaching Others The Truth About Vodou And Hoodoo

Manbo Jessyka Winston had no plans to turn her spiritual practice into a business. However, in 2016, Winston believes her spirits guided her to create Haus of Hoodoo, a New Orleans-based botanica, or religious store, with an Instagram following of more than 100,000.

The native of Ayiti is now using her social media platform as a tool to help combat some of the false beliefs surrounding Vodou and Hoodoo.

Vodou means “spirit or deity” in the Fon language of what is now Benin. Africans who were enslaved and brought to colonial Saint-Domingue, or present-day Haiti, developed the practice in the 16th and 17th centuries. One of the main ideologies of Vodou is that humans live among Iwa, or spirits, as well as Mystè (mysteries), Anvizib (the invisibles), Zanj (angels) and souls of the ancestors. Winston is a “manbo,” a Vodou priestess.

“Vodou is something that’s just always part

Antarctic Ice Sheet to melt, raise sea levels by 8.5 feet even under Paris Agreement

Sept. 23 (UPI) — The Antarctic Ice Sheet will suffer irreversible ice loss raising ocean levels by 8.5 feet even if the world meets global warming goals laid out by the Paris Agreement on Climate change, scientists said in a report published Wednesday.

The analysis determined there are a number of temperature thresholds above pre-industrial levels that will ultimately lead to increasing sea levels if the world’s nations don’t rein in emissions and global warming.

The study, published Wednesday in the journal nature, was conducted by researchers at the Potsdam Institute for Climate Impact Research and the University of Potsdam in Germany, Columbia University in New York City, and Stockholm University in Sweden.

The researchers determined that if global warming is maintained at 2 degrees Celsius above pre-industrial levels — as laid out by the Paris Agreement — sea levels would rise by 8.5 feet.

If the climate agreement is

Mystery of giant proton pump solved

Mitochondria are the powerhouses of our cells, generating energy that supports life. A giant molecular proton pump, called complex I, is crucial: It sets in motion a chain of reactions, creating a proton gradient that powers the generation of ATP, the cell’s fuel. Despite complex I’s central role, the mechanism by which it transports protons across the membrane has so far been unknown. Now, Leonid Sazanov and his group at the Institute of Science and Technology Austria (IST Austria) have solved the mystery of how complex I works: Conformational changes in the protein combined with electrostatic waves move protons into the mitochondrial matrix. This is the result of a study published today in Science.


Complex I is the first enzyme in the respiratory chain, a series

Hundreds of whales wash ashore in Tasmania, leaving scientists puzzled

The deaths of nearly 400 pilot whales on the shore of Tasmania’s west coast has captured global attention, both for the rescue efforts from local agencies and for the puzzling cause behind such a tragic event.

Images captured by helicopters paint the stunning scene, as the bodies of the hundreds of massive sea creatures lay in the shallow waters of the Macquarie Harbor.

Whale carcasses are scattered along the water’s edge near Strahan, Australia, Wednesday, Sept. 23, 2020. Authorities revised up the number of pilot whales rescued from Australia’s worst-ever mass stranding from 50 to 70 on Thursday, Sept. 24, 2020, as the focus shifted to removing 380 carcasses from Tasmania state shallows.

According to authorities, 70 beached whales were rescued by locals and staff members from the Tasmania Parks and Wildlife Service. Marine and Conservation Program wildlife biologist Dr. Kris Carlyon said the stranding

What the post-coronavirus workplace might look like

What will the post-Covid workplace look like? Steelcase is one of the largest manufacturers of office furniture — desks, chairs, storage products and office pods — and they have a lot of ideas.

They are partnering with MIT to better understand how air circulates in an office environment.

“Well, we know that the six-foot rule is not as simple as that,” CEO Jim Keane told me. “The science shows that particles travel through the air, depending on whether they’re larger particles or smaller particles, based on models that MIT has built. So, we’re using those models to test different kinds of furniture configurations to identify which furniture will best protect the workforce in the future.”

“In the very short run, offices need more separation between desks, and, in some cases, screens or partitions in order to comply with science-based guidelines, for example, the 6-foot rule,” Keane said. “Our own analysis
