Researchers at the George Washington University have taken a major step toward reaching one of the most sought-after goals in physics: room temperature superconductivity.

Superconductivity is the lack of electrical resistance and is observed in many materials when they are cooled below a critical temperature. Until now, superconducting materials were thought to have to cool to very low temperatures (minus 180 degrees Celsius or minus 292 degrees Fahrenheit), which limited their application. Since electrical resistance makes a system inefficient, eliminating some of this resistance by utilizing room temperature superconductors would allow for more efficient generation and use of electricity, enhanced energy transmission around the world and more powerful computing systems.

“Superconductivity is perhaps one of the last great frontiers of scientific discovery that can transcend to everyday technological applications,” Maddury Somayazulu, an associate research professor at the GW School of Engineering and Applied Science, said. “Room temperature superconductivity has been the proverbial ‘holy grail’ waiting to be found, and achieving it—albeit at 2 million atmospheres—is a paradigm-changing moment in the history of science.”

A small cotton shoot is growing onboard Chang’e 4 lunar lander, scientists confirm.

Astronomers using the ALMA telescope have discovered an oddly tilted planet-forming disk within a double binary star system, a configuration that up until this point only existed in theory.

Quadruple star systems featuring two binary pairs are nothing unusual, nor is the discovery of a surrounding protoplanetary disk—a ring of gas and dust that gradually congeals to form planets. A star system located 146 light-years from Earth, called HD 98800, has all these things, but as new research published today in Nature Astronomy reveals, this system features an exceptionally strange protoplanetary disk.

In the study, researchers focused on a mechanism that routinely serves the cell by marking human virus-like genes in order to avoid identifying them as viruses. Together with the Harvard team, Levanon has discovered that “when inhibiting this mechanism, the immune system can be harnessed to fight cancer cells in a particularly efficient manner, and most effectively in lung cancer and melanoma.”

“We found that if the mechanism is blocked, the immune system is much more sensitive,” Levanon said. “When the mechanism is deactivated, the immune system becomes much more aggressive against the tumor cells.”

According to researchers, most patients with cancer either do not respond to immune checkpoint blockade (a type of drug that blocks certain proteins made by some types of immune system cells, such as T cells, and some cancer cells) or develop resistance to it. The National Cancer Institute (NCI) says these proteins help keep immune responses in check and can keep T cells from killing cancer cells. “When these proteins are blocked, the ‘brakes’ on the immune system are released and T cells are able to kill cancer cells better,” says the NCI. Some immune checkpoint inhibitors are used to treat cancer as immunotherapy uses the body’s immune system to fight cancer.

The dark waters of a lake deep beneath the West Antarctic ice sheet and a few hundred miles from the South Pole are teeming with bacterial life, say scientists — despite it being one of the most extreme environments on Earth.

The discovery has implications for the search for life on other planets — in particular on the planet Mars, where signs of a buried lake of liquid saltwater were seen in data reported last year by the European Space Agency’s orbiting Mars Express spacecraft.

Expedition leader John Priscu, a professor of polar ecology at the University of Montana, told Live Science in a telephone interview from Antarctica this week that early studies of water samples taken from Lake Mercer — which is buried beneath a glacier — showed that they contained approximately 10,000 bacterial cells per milliliter.

The proposed facility would become the most powerful collider ever built.

For the first time, scientists have used rapid 3D printing technologies to create a spinal cord. The team at UC San Diego then put neural cells in it and implanted it into rats, who walked again.
