Baby corals are just as susceptible as adults to deadly reef disease

Baby corals are just as susceptible as adults to a deadly disease that has been spreading across Florida's reefs since 2014, according to a new study. The findings showed that stony coral tissue loss disease (SCTLD) infects baby corals with similar severity and mortality that we see in adult colonies. This is the first study to show the impacts of any coral disease on baby corals.

Baby corals are just as susceptible as adults to deadly reef disease, study finds

Baby corals are just as susceptible as adults to a deadly disease that has been spreading across Florida's reefs since 2014, according to a new study led by scientists at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science. The findings showed that stony coral tissue loss disease (SCTLD) infects baby corals with similar severity and mortality that we see in adult...

Getting a better view of landslide risk with LiDAR

In the mountains of North Carolina, landslides are no joke. Triggered by heavy rains, mountainside soils can become saturated and "unstuck." As a result, what starts as a small landslide can quickly escalate into a huge debris flow that uproots trees and dislodges boulders, scouring everything in its path as it quickly flows downhill at speeds up to 30 mph. The cost—in both infrastructure and...

Uncovering warped protein interactions in cancer

Scientists at Emory have revealed widespread distortions of a cell's protein interaction machinery resulting from cancer-causing mutations. They developed a process resembling ground-penetrating radar, for its ability to map the hidden landscape of anti-cancer drug opportunities.

Scientists discover comet's hourglass-shaped dust trail

Researchers from Finland, Canada, and Russia have discovered an unusual, hourglass-shaped dust trail of the comet 17P/Holmes. The particles that formed the dust trail were released by the most powerful of the thus-far documented outbursts by a comet. It happened in October 2007. Astronomers carried out observations of the cometary dust trail using telescopes in Australia, Finland, and the U.S. The...

The Laser Interferometer Space Antenna reaches a crucial milestone

LISA, the Laser Interferometer Space Antenna, has reached an important milestone: it has passed the comprehensive "Mission Formulation Review" (MFR) and now enters the next phase of development. The review team, consisting of experts from ESA, NASA, the scientific community and industry, identified no showstoppers and confirmed that LISA has successfully reached a maturity sufficient to proceed to...

New black hole sonifications with a remix are now available for listening

Since 2003, the black hole at the center of the Perseus galaxy cluster has been associated with sound. This is because astronomers discovered that pressure waves sent out by the black hole caused ripples in the cluster's hot gas that could be translated into a note—one that humans cannot hear, some 57 octaves below middle C. Now a new sonification brings more notes to this black hole sound...

A 'factory reset' for the brain may cure anxiety, drinking behavior, study suggests

Gene editing may be a potential treatment for anxiety and alcohol use disorder in adults who were exposed to binge drinking in their adolescence, according to the results of an animal study. The researchers used a gene-editing tool called CRISPR-dCas9 in their experiments to manipulate the histone acetylation and methylation processes at the Arc gene in models of adult rats.
