Early clinical trial data show gene therapy reversing sickle cell anemia

After over a decade of preclinical research and development, a new gene therapy treatment for sickle cell anemia (SCA) is reversing disease symptoms in two adults and showing early potential for transportability to resource-challenged parts of the world where SCA is most common.

NASA's OSIRIS-REx spacecraft arrives at asteroid Bennu

NASA's Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer (OSIRIS-REx) spacecraft completed its 1.2 billion-mile (2 billion-kilometer) journey to arrive at the asteroid Bennu Monday. The spacecraft executed a maneuver that transitioned it from flying toward Bennu to operating around the asteroid.

Life has a new ingredient

Our prehistoric Earth, bombarded with asteroids and lightening, rife with bubbling geothermal pools, may not seem hospitable today. But somewhere in the chemical chaos of our early planet, life did form. How? For decades, scientists have created miniature replicas of infant Earth in the lab in order to hunt for life's essential ingredients. Now, one of those replicas points to a possible new ingredient in the world's first RNA.

New quantum materials could take computing devices beyond the semiconductor era

Scientists in industry and academia are looking for new materials to succeed highly successful semiconductor transistors. Scientists have hit on a very promising post-transistor technology: multiferroics, which use magnetic spin states instead of electron charge to store binary data. They have shown that these MESO (magneto-electric spin-orbit) devices can greatly improve energy efficiency and pack more logic devices onto a chip.

In death, Lonesome George reveals why giant tortoises live so long

Genetic analysis of DNA from Lonesome George and samples from other giant tortoises of the Galapagos -- which can live more than 100 years in captivity -- found they possessed a number of gene variants linked to DNA repair, immune response, and cancer suppression not possessed by shorter-lived vertebrates.

Will light be the basis for quantum computing?

Using a compact optical platform that exploits the quantum characteristics of light, scientists are one step closer to realizing the first powerful photonic quantum computer. The researchers revealed to have generated a particular class of quantum states - d-level cluster states, robust and powerful than any other such states demonstrated thus far -, as well as to have used them to implement novel quantum operations.

LIGO and Virgo announce four new gravitational-wave detections

The LIGO and Virgo collaborations have now confidently detected gravitational waves from a total of 10 stellar-mass binary black hole mergers and one merger of neutron stars, which are the dense, spherical remains of stellar explosions. Six of the black hole merger events had been reported before, while four are newly announced.

Combination of space-based and ground-based telescopes reveals more than 100 exoplanets

Astronomers using a combination of ground and space based telescopes have reported more than 100 extrasolar planets (exoplanets) in only three months. These planets are quite diverse and expected to play a large role in developing the research field of exoplanets and life in the Universe.
