If clinically validated, the DeepDOF microscope could allow surgeons to inspect tumor margins within minutes.
Alzheimer's disease: regulating copper in the brain stops memory loss among mice
- EurekAlert
- 20/12/17 06:00
Alzheimer's disease is characterized by the presence of amyloid plaques1 in the patient's brain. These plaques sequester copper, and contain approximately five times as much as a healthy brain. Two CNRS scientists from the Coordination Chemistry Laboratory recently developed, with their colleagues from the Guangdong University of Technology and Shenzhen University (China), a molecule that...

Big data will analyze the mystery of Beethoven's metronome
- EurekAlert
- 20/12/17 06:00
Data science and physics research at the Universidad Carlos III de Madrid and UNED has analysed a centuries-old controversy over Beethoven's annotations about the tempo (the playing speed) of his works, which is considered to be too fast based on these marks. In this study, published in the PLOS ONE journal, it is noted that this deviation could be explained by the composer reading the metronome...
Can water saving traits help wine survive climate change?
- EurekAlert
- 20/12/17 06:00
Climate change is expected to make many grape-growing regions too hot and dry to produce high-quality wine from traditional varieties. But scientists at the University of California, Davis, have found that wine grape varieties from regions that are more prone to stress have traits that could help them cope with climate change.

Catalysts are indispensable for many technologies. To further improve heterogeneous catalysts, it is required to analyze the complex processes on their surfaces, where the active sites are located. Scientists of Karlsruhe Institute of Technology (KIT), together with colleagues from Spain and Argentina, have now reached decisive progress: As reported in Physical Review Letters, they use calculation...
Cataract surgery in infancy increases glaucoma risk
- EurekAlert
- 20/12/17 06:00
Children who undergo cataract surgery as infants have a 22% risk of glaucoma 10 years later, whether or not they receive an intraocular lens implant. The findings come from the National Eye Institute (NEI)-funded Infant Aphakic Treatment Study, which today published 10-year follow-up results in JAMA Ophthalmology. NEI is part of the National Institutes of Health.
CCNY scientists provide new insights into cholera microbe and chances of pandemic strain
- EurekAlert
- 20/12/17 06:00
Researchers at The City College of New York have uncovered a novel way in which Vibrio cholerae, the aquatic microbe that causes cholera, may increase its competitive fitness, and the likelihood of creating pandemic strains of the bacteria.
Change in global precipitation patterns as a result of climate change
- EurekAlert
- 20/12/17 06:00
The Earth's climate system is largely determined by the differences in temperature between the tropics and the poles. Global warming is likely to cause global atmospheric circulation to change and progressively revert to a situation similar to that of 5,000 to 10,000 years ago. This is the conclusion of a study published in Nature Communications.
Childhood intervention can prevent 'deaths of despair'
- EurekAlert
- 20/12/17 06:00
Mortality rates among young adults are rising in the US due in part to 'deaths of despair' -- preventable deaths from suicide, drug overdoses and alcohol-related liver disease. An intensive childhood intervention program called Fast Track could help reduce these deaths by reducing risky behaviors in adolescence and young adulthood, finds new research from Duke University and the Conduct Problems...
Computational model reveals how the brain manages short-term memories
- EurekAlert
- 20/12/17 06:00
Salk scientists have developed a new computational model showing how the brain maintains information short-term using specific types of neurons. Their findings, published in Nature Neuroscience on December 7, 2020, could help shed light on why working memory is impaired in a broad range of neuropsychiatric disorders, including schizophrenia, as well as in normal aging.

- EurekAlert
- 20/12/17 06:00
DALLAS - Dec. 17, 2020 - DNA that ends up where it doesn't belong in cancer cells can unleash an immune response that makes tumors more susceptible to immunotherapy, the results of two UT Southwestern studies indicate. The findings, published online today in Cancer Cell, suggest that delivering radiation - which triggers DNA release from cells - before immunotherapy could be an effective way to...
