Baby corals are just as susceptible as adults to deadly reef disease
Engineers have demonstrated the effectiveness of new technology to cut diesel emissions. The advancement successfully reduced heavy-duty diesel engine nitrogen oxide (NOx) emissions to meet the California Air Resources Board (CARB) 2027 standards.

Higher antioxidant levels linked to lower dementia risk
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.

Neuroscientists find multiple brain regions control speech, challenging common assumption
People with higher levels of antioxidants in their blood may be less likely to develop dementia, according to a new study.

Baby corals are just as susceptible as adults to deadly reef disease, study finds
Neurobiologists give new meaning to the term 'motor mouth'. By carefully mapping neural networks in marmoset and macaque monkeys, they determined that multiple areas in the brain's frontal lobe control the muscles of vocalization and could provide a foundation for complex speech.
Getting a better view of landslide risk with LiDAR
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...
Uncovering warped protein interactions in cancer
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...
To refine water forecasts, Western cities map snow by plane
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.
New study provides insight on Britons living in the EU post-Brexit
At a tiny airport surrounded by mountains, a three-person crew takes off for the inaugural flight above the headwaters of the Colorado River to measure the region's snow by air.
California's 2020 wildfire season: Report summarizes record-breaking fire year and calls for shift in strategy
A new picture of Britons living in the EU post-Brexit flags the "deep transformation" that has come with the removal of freedom of movement.
Mentioning 'white privilege' increases online polarization, finds a new study
Just over 9,900 wildfires burned about 4.3 million acres in 2020. That's more than twice the previous record of acres burned in California. Yet it is about average compared to burn rates likely experienced before Euro-American settlement, according to a study from the University of California, Davis, that summarizes the 2020 fire season and examines its drivers.
Will climate change increase the risk of aflatoxin in US corn?
If there's an online discussion about race, using the term "white privilege" can create a polarized situation, say University of Michigan researchers.
Scientists discover comet's hourglass-shaped dust trail
As climate change continues to alter weather patterns around the planet including the Midwest, researchers at Michigan State University (MSU) are modeling the impact on crops such as corn.
Major 2020 Alaska quake triggered neighboring 2021 temblor
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
A study of two powerful earthquakes in adjacent areas off the Alaska Peninsula in 2020 and 2021 shows a connection between the two. It also suggests they may be a part of an 80-year rupture cascade along the fault.
Researchers develop new evolutionary approach for identifying proteins that functionally interact
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
Jacob Steenwyk, a graduate student in biological sciences, and collaborators at Vanderbilt, Tel Aviv University and University of Wisconsin-Madison measured the coevolution of pairs of genes shared across budding yeasts to identify the genes that participate in the same cellular or molecular functions.
A 'factory reset' for the brain may cure anxiety, drinking behavior, study suggests
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...

Will climate change increase the risk of aflatoxin in U.S. corn?
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.

The gene-edited pig heart given to a dying patient was infected with a pig virus
An analysis of more than 400 singers who sought treatment for vocal injuries provides a wealth of data on a topic that's often considered taboo to discuss in the singing community.
Links between paranormal beliefs and cognitive function described by 40 years of research
The pig heart transplanted into an American patient earlier this year in a landmark operation carried a porcine virus that may have derailed the experiment and contributed to his death two months later, say transplant specialists. David Bennett Sr. was near death in January when he received a genetically edited pig heart in a pioneering…

Scientists identify the most extreme heatwaves ever recorded globally
In a review of 71 studies that explored links between belief in paranormal phenomena and cognitive function, most of the findings align with the hypothesis that such beliefs are associated with cognitive differences or deficits.

A new study has revealed the most intense heatwaves ever across the world -- and remarkably some of these went almost unnoticed decades ago.
