New technology reduces heavy-duty diesel emissions to meet stringent CARB 2027 NOx requirements
- ScienceDaily
- 22/5/4 23:08
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.
Baby corals are just as susceptible as adults to deadly reef disease
- ScienceDaily
- 22/5/4 23:08
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
- ScienceDaily
- 22/5/4 23:08
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.
A 'factory reset' for the brain may cure anxiety, drinking behavior, study suggests
- ScienceDaily
- 22/5/4 21:36
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.

- 22/5/4 21:12
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
- ScienceDaily
- 22/5/4 20:45
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.
Scientists identify the most extreme heatwaves ever recorded globally
- ScienceDaily
- 22/5/4 20:45
A new study has revealed the most intense heatwaves ever across the world -- and remarkably some of these went almost unnoticed decades ago.
Scientists engineer new tools to electronically control gene expression
- ScienceDaily
- 22/5/4 20:45
Researchers have created an improved method for turning genes on and off using electrical signals.
Researchers find link between Parkinson's gene and vocal issues that could lead to earlier diagnosis
- ScienceDaily
- 22/5/4 20:45
Neuroscientists found that higher levels of the alpha-synuclein protein in the brain can lead to changes in vocal production.
Patients with past cancer history not associated with higher risk of COVID-19-related death or hospitalization
- ScienceDaily
- 22/5/4 20:45
Patients diagnosed with cancer more than one year ago and those not receiving active treatment were no more vulnerable to worse COVID-19 outcomes than patients without cancer, according to a new study.
California's 2020 wildfire season
- ScienceDaily
- 22/5/4 20:45
A new study summarizing the 2020 California wildfire year said just over 9,900 wildfires burned 4.3 million acres in 2020. That's twice the previous record but only average compared to burn rates before Euro-American settlement. Fire severity is the far greater concern.
Major 2020 Alaska quake triggered neighboring 2021 temblor
- ScienceDaily
- 22/5/4 20:45
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.
Daily steroids safe and slows progression of duchenne muscular dystrophy, study suggests
- ScienceDaily
- 22/5/4 19:56
New research recommends daily steroid doses for children with Duchenne muscular dystrophy, marking a significant change in how the disease is treated.
New study reviews anti-cancer activity of sustained release capsaicin formulations
- ScienceDaily
- 22/5/4 19:56
A study provides the first published in-depth description of the anti-cancer activity of capsaicin sustained release formulations. Capsaicin is naturally found in chili peppers and is the agent that provides the hot and spicy taste when eating chili peppers.
Bye, bye, biopsy? Handheld device could painlessly identify skin cancers
- ScienceDaily
- 22/5/4 19:56
A new device uses millimeter-wave imaging -- the same technology used in airport security scanners -- to scan a patient's skin to detect if they have skin cancer. Millimeter-wave rays harmlessly penetrate about 2mm into human skin, so the team's imaging technology provides a clear 3D map of scanned skin lesions.
How mosquito brains encode human odor so they can seek us out
- ScienceDaily
- 22/5/4 19:08
Some strains of Aedes aegypti -- the mosquito that carries Zika, malaria and dengue fever -- have evolved to bite humans almost exclusively. A team has now discovered how they target us so precisely.
The quest for an ideal quantum bit
- ScienceDaily
- 22/5/4 19:08
Scientists have developed a qubit platform formed by freezing neon gas into a solid, spraying electrons from a light bulb's filament onto it, and trapping a single electron there. This system shows great promise as an ideal building block for quantum computers.
Surprising risk factors may predict heart attacks in young women
- ScienceDaily
- 22/5/4 19:08
A new study has for the first time identified which risk factors are more likely to trigger a heart attack or acute myocardial infarction (AMI) for men and women 55 years and younger.
A new 225-million-year-old reptile from Brazil

- 22/5/4 19:08
A reassessment of Faxinalipterus minimus, a purported Triassic pterosaur from southern Brazil resulted in the description of a new taxon -- researchers present Maehary bonapartei a small reptile that is considered to be the most basal of the evolutionary lineage that gave rise to pterosaurs. The study also demonstrates that Faxinalipterus minimus is not a winged reptile, contrary to what was...
Astronomers discover a rare 'black widow' binary, with the shortest orbit yet

Astronomers discovered a 'black widow binary' -- a rapidly spinning neutron star circling and slowly consuming a smaller companion star. Named ZTF J1406+1222, the pair has the shortest orbital period yet identified, and is unique in that it appears to host a third star that orbits around the two inner stars every 10,000 years.
