The study suggests an increasing risk of future megadroughts in the American Southwest due to climate change.

Atmosphere of midsize planet revealed by Hubble, Spitzer

Two NASA space telescopes have identified the detailed chemical 'fingerprint' of a planet between the sizes of Earth and Neptune. No planets like this can be found in our own solar system, but they are common around other stars.

Physicists use light waves to accelerate supercurrents, enable ultrafast quantum computing

Scientists have discovered that terahertz light -- light at trillions of cycles per second -- can act as a control knob to accelerate supercurrents. That can help open up the quantum world of matter and energy at atomic and subatomic scales to practical applications such as ultrafast computing.

Researchers decipher the history of supermassive black holes in the early universe

Astrophysicists have found evidence for the direct formation of black holes that do not need to emerge from a star remnant. The production of black holes in the early universe, formed in this manner, may provide scientists with an explanation for the presence of extremely massive black holes at a very early stage in the history of our universe.

Researchers grow active mini-brain-networks

Cerebral organoids are artificially grown, 3D tissue cultures that resemble the human brain. Now, researchers report success with functional neural networks derived from these organoids. Although the organoids aren't actually 'thinking,' the researchers' new tool -- which detects neural activity using organoids -- could provide a method for understanding human brain function.

Wood products mitigate less than one percent of global carbon emissions

The world's wood products -- all the paper, lumber, furniture and more -- offset just one percent of annual global carbon emissions by locking away carbon in woody forms, according to new research.

Evolution of life in the ocean changed 170 million years ago

New research identifies a previously overlooked global event which changed the course of the evolution of life in the oceans. It coincided with a rise in calcium carbonate-secreting plankton and their subsequent deposition on the ocean floor.

Space station mold survives high doses of ionizing radiation

The International Space Station, like all human habitats in space, has a nagging mold problem. Astronauts on the ISS spend hours every week cleaning the inside of the station's walls to prevent mold from becoming a health problem. New research finds mold spores may also survive on the outside walls of spacecraft.

NASA's TESS mission finds its smallest planet yet

NASA's Transiting Exoplanet Survey Satellite (TESS) has discovered a world between the sizes of Mars and Earth orbiting a bright, cool, nearby star. The planet, called L 98-59b, marks the tiniest discovered by TESS to date.
