In a statement, Roscosmos noted that the first missions to explore Venus were carried out by the Soviet Union.

“The enormous gap between the Soviet Union and its competitors in the investigation of Venus contributed to the fact that the United States called Venus a Soviet planet,” Roscosmos said.

The Russians claim to have extensive material that suggests that some objects on the Venusian surface have changed places or could be alive, although these are hypotheses that have yet to be confirmed.

Over the past five decades, space travel advocates have been pushing to expand our footprint in space. They dream about lunar bases, missions to Mars and colonies in free space. The visions are ever changing, with government efforts joined by those of private companies like Elon Musk’s SpaceX — in the midst of an effort to send tourists on a trip around the Moon — gravitating toward the space tourism sector. While the goals and how to accomplish them are in constant flux, there remain certain obstacles that must be overcome before we take that next big step. And one of the biggest is the need to protect the health of our future space explorers.

That’s what’s prompted NASA to turn to the fast-moving world of gene therapy to solve several potential medical issues facing astronauts on lengthy space missions.

The US space agency and the associated Translational Institute for Space Health Research (TRISH) at the Baylor College of Medicine are now calling for proposals from private companies and other groups to develop a kind of gene therapy for astronauts. But this would be different than recent gene therapies that target specific diseases such as hemophilia or various types of cancer. Instead, the idea here is to minimize the damage from space radiation through a kind of preventive treatment. Exposure to radiation in space can cause cancer, cardiovascular disease, cataracts and the loss of cognitive function due to accelerated death of brain cells. These different disease categories involve very different mechanisms — cancer and heart disease result from radiation damaging DNA, while loss of brain tissue results simply from radiation killing off mature cells, and still other diseases result from radiation destroying stem cells.

When a virus invades your cells, it changes your body. But in the process, the pathogen changes its shape, too. A new mathematical model predicts the points on the virus that allow this shape-shifting to occur, revealing a new way to find potential drug and vaccine targets. The unique math-based approach has already identified potential targets in the coronavirus that causes COVID-19.

Outlined in April in the Journal of Computational Biology, the strategy predicts protein sites on viruses that stash energy—important spots that drugs could disable. In a rare feat, the work proceeds from pure mathematics, says study author and mathematician Robert Penner of the Institute of Advanced Scientific Studies in France. “There’s precious little pure math in biology,” he adds. The paper’s predictions face a long road before they can be verified experimentally, says John Yin, who studies viruses at the University of Wisconsin–Madison and was not involved in the research. But he agrees that Penner’s approach has potential. “He’s coming at this from a mathematician’s point of view—but a very scientifically informed mathematician,” Yin says. “So that’s highly rare.”

Penner’s method takes advantage of the fact that certain viral proteins alter their shape dramatically when viruses breach cells, and this transformation depends on unstable features. (A stable protein site, by definition, resists change.) By identifying “high free energy sites”—areas on a viral protein that store lots of energy—Penner realized he could spot likely “spring” points that mediate this change in shape. He calls such high-energy spots exotic sites. Finding them required some complex math.

Akon has released detailed plans of Akon City, his $6 billion futuristic cryptocurrency city, which he calls a “real-life Wakanda,” referring to the hit movie Black Panther. There will be seven major districts, and the city will be run on the akoin cryptocurrency.

Senegalese-American star and philanthropist Akon, whose full name is Aliaune Damala Badara Akon Thiam, unveiled Monday some major details of his planned Akon City. The $6 billion futuristic city in Senegal, Africa, will be run on the akoin cryptocurrency.

The city will be divided into seven major districts: the African culture village district, the offices and residential district, the entertainment district, the health and safety district, the education district, the technology district, and the Senewood district.

Engineers from Caltech and NASA’s Jet Propulsion Lab built a three-inch drone that could be launched from a barrel. It’s called SQUID, or the Streamlined Quick Unfolding Investigation Drone. And this year, the team has debuted a larger six-inch version of the drone.

A team of astrobiologists from NASA’s Goddard Space Flight Center and the Carnegie Institution for Science has found a wide diversity of amino acids in Asuka 12236, a carbonaceous chondrite meteorite recovered from the Nansen Ice Field in Antarctica by Belgium and Japan researchers in 2012.

Boosting seedling survival rates from 10% to at least 90%.

Conserving existing forests, restoring forest ecosystems and reforesting suitable lands is essential if we are to transition to a sustainable pathway for our economies and societies at the required speed and scale.

Such a transformation is the goal of 1t.org – the Trillion Tree Platform announced at the World Economic Forum Annual Meeting 2020 in Davos. Set up to support the UN Decade on Ecosystem Restoration (2021−2030), 1t.org seeks to raise ambition for 1 trillion tree commitments and empower and connect a global community of innovators and ecopreneurs who are developing the needed solutions to achieve the trillion trees goal.

Battery technology is key to Tesla’s future — for more reasons than its electric cars.

Summary: Researchers found specific neurons in the striosome that help mice learn to avoid negative experiences.

Cold Spring Harbor Laboratory (CSHL) scientists have discovered neurons in the mouse brain that help an animal learn to avoid negative experiences. The cells reside in a part of the brain involved in regulating the motivations that influence behavior.
