Fusion Researchers Find Safer, More Effective Way to Create a Star on Earth

Posted by in category: nuclear energy

A major issue with operating ring-shaped fusion facilities known as tokamaks is keeping the plasma that fuels fusion reactions free of impurities that could reduce the efficiency of the reactions. Now, scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory ( PPPL ) have found that sprinkling a type of powder into the plasma could aid in harnessing the ultra-hot gas within a tokamak facility to produce heat to create electricity without producing greenhouse gases or long-term radioactive waste.

Fusion, the power that drives the sun and stars, combines light elements in the form of plasma — the hot, charged state of matter composed of free electrons and atomic nuclei — that generates massive amounts of energy. Scientists are seeking to replicate fusion on Earth for a virtually inexhaustible supply of power to generate electricity.

Tumor-Infiltrating Lymphocytes ‘Capable of Destroying the Last Cancer Cell’

Posted by in category: biotech/medical

Nearly a quarter of patients, 23.7%, treated with adoptive cell transfer tumor-infiltrating lymphocytes for metastatic melanoma have experienced complete and durable responses, according to data presented at ASCO Annual Meeting.

The trial (NCT01174121), conducted by the NCI, has been enrolling patients since 2010, and the subset of patients with metastatic melanoma have shown impressive responses to the therapy over time, with only two complete responders experiencing disease recurrence that resulted in death.

“We have a group of 44 patients with melanoma that are likely cured. They have had no other treatment since their TIL and have been free of disease for more than 5 years,” Stephanie L. Goff, MD, FACS, an associate research physician with the surgery branch at the NCI, told Cell Therapy Next.

First chip-to-chip quantum teleportation harnessing silicon photonic chip fabrication

Posted by in categories: internet, particle physics, quantum physics, supercomputing

The development of technologies which can process information based on the laws of quantum physics are predicted to have profound impacts on modern society.

For example, quantum computers may hold the key to solving problems that are too complex for today’s most powerful supercomputers, and a quantum internet could ultimately protect the worlds information from malicious attacks.

However, these technologies all rely on “,” which is typically encoded in single quantum particles that are extremely difficult to control and measure.

Incredible sights from space as astronauts celebrate Christmas and Hanukkah

Posted by in category: space

Astronauts may be far from home, but they still celebrate the holidays.

Residents of the International Space Station posted an incredible photo and video for the holidays, celebrating both Hanukkah and Christmas far above the world.

Astronaut Jessica Meir posted a stunning picture from the station’s cupola, the small, panoramic, ESA-built observatory module of the station. It allows for observation of activities like spacewalks and shuttle approaches, but also provides the perfect place to celebrate Hanukkah.
