Frequent marijuana use linked to heart disease
2023-02-24
People who used marijuana daily were found to be about one-third more likely to develop coronary artery disease (CAD) compared with people who have never used the drug, according to a study presented at the American College of Cardiology’s Annual Scientific Session Together With the World Congress of Cardiology.
As cannabis becomes legal in an increasing number of U.S. states, this study is among the largest and most comprehensive to date to examine the potential long-term cardiovascular implications of using the drug. CAD is the most common form of heart disease and occurs when the arteries that supply blood to the heart ...
Cognitive behavioral therapy delivered via smartphone app lowers blood sugar, improves health behaviors in patients with diabetes
2023-02-24
People with Type 2 diabetes who were given a smartphone app that delivers personalized cognitive behavioral therapy (CBT) saw significantly greater reductions in their blood sugar and less need for higher doses of diabetes medications at six months compared with those who only received standard diabetes care and a control app, in a study presented at the American College of Cardiology’s Annual Scientific Session Together With the World Congress of Cardiology. A clear “dose effect” was seen, with patients completing more CBT lessons seeing the greatest benefits.
“When studied in a large randomized controlled ...
Is the middle Cambrian Brooksella a hexactinellid sponge, trace fossil or pseudofossil?
2023-02-24
More than 100 years ago, Charles Doolittle Walcott from the Smithsonian Institution was asked to examine strange star-shaped fossils with lobes hailing from the ~ 514-million-year-old Conasauga Formation in Alabama. Walcott described these odd fossils as jellyfish that likely floated in the middle Cambrian seas of what is now the southeastern United States. Little did he know that the Cambrian fossil he named would cause over 100 years of controversy.
The controversy hinged on the interpretation of what Brooksella really was: Was it truly a jellyfish ...

Faster and sharper whole-body imaging of small animals with deep learning
2023-02-24
It takes a few moments for the sound of thunder to reach our ears after a flash of lightning. This phenomenon is due to the photoacoustic (PA) effect where materials near the lightning instantly expand as the optical energy of the lightning is absorbed and converted into thermal energy. Using this PA effect, photoacoustic computed tomography (PACT) has become a premier preclinical and clinical imaging modality to take images inside the body without using a contrast medium. However, its low-quality images, which can be improved with multiple ultrasound sensors and a multi-channel data acquisition (DAQ) system, ...
Calming the destructive cells of ALS by two independent approaches
2023-02-24

· Normally supportive cells attack the diseased neurons and destroy them
· This pathology occurs in 90% of ALS patient brains and in frontotemporal dementia and Alzheimer’s disease
CHICAGO --- Northwestern Medicine scientists have discovered two ways to preserve diseased upper motor neurons that would normally be destroyed in ALS, based on a study in mice. Upper motor neurons initiate movement, ...
Marine heatwaves decimate sea urchins, molluscs and more at Rottnest
2023-02-24
Curtin University researchers believe rising sea temperatures are to blame for the plummeting number of invertebrates such as molluscs and sea urchins at Rottnest Island off Western Australia, with some species having declined by up to 90 per cent between 2007 and 2021.
Lead author Adjunct Professor Fred Wells, from Curtin’s School of Molecular and Life Sciences, said the west end of Rottnest Island had suffered a “catastrophic decline” in biodiversity.
“Since 1982, we have monitored biodiversity of marine molluscs and echinoderms ...
Ultrafast synthesis of cobalt/carbon nanocomposites by magnetic induction heating for oxygen evolution reaction
2023-02-24
This study is led by Dr. Shaowei Chen (University of California). Natural gas reforming accounts for 95% of the hydrogen gas produced in the United States; yet the hydrogen is non-sustainable and “grey”, as it originates from fossil fuels . To obtain sustainable “green” hydrogen gas, electrochemical water splitting by using renewable electricity has emerged as one of the most promising technologies, which consists of hydrogen evolution reaction (HER) at the cathode and oxygen evolution reaction (OER) at the anode . Yet, due to the sluggish electron-transfer kinetics and complex reaction pathways, OER typically entails a large overpotential and severely ...

“First, software today is everywhere; organisations, companies, governments ...
How the close dinosaurian relatives of birds evolved gigantic and miniature sizes
2023-02-23
An analysis of fossils of non-avialan theropod dinosaurs – a dinosaur clade that includes an array of body sizes – has provided findings that run contrary to expectations regarding the factors that inform the evolution of body size diversity. “Once quantified and analyzed in a phylogenetic framework [like this], we predict that diverse growth strategies will be recognized in other clades,” say the study’s authors. Over evolutionary history, many taxa have evolved very large and very small body sizes, and even closely related species can exhibit widely disparate sizes. ...
How does a person’s ethnicity impact their risk of death?
2023-02-23
In the UK, disparities in mortality risk factors exist between ethnic groups, with differences in overall mortality, top causes of mortality and individual mortality risk factors, according to a new study published this week in the open-access journal PLOS Global Public Health by I. King Jordan of Georgia Institute of Technology, US, and colleagues.

Plastic upcycling to close the carbon cycle
2023-02-23
RICHLAND, Wash.—There’s a lot of potentially useful raw materials bound up in used face masks, grocery bags and food wrap. But it has been much cheaper to keep making more of these single-use plastics than to recover and recycle them.
Now, an international research team led by the Department of Energy’s Pacific Northwest National Laboratory has cracked the code that stymied previous attempts to break down these persistent plastics. They reported their discovery in today’s issue of Science.
Low temperature and reaction control
Typically, recycling plastics requires ‘cracking’ or ...
Evolution of dinosaur body size through different developmental mechanisms
2023-02-23
The meat-eating dinosaurs known as theropods that roamed the ancient Earth ranged in size from the bus-sized T. rex to the smaller, dog-sized Velociraptor. Scientists puzzling over how such wildly different dinosaur sizes evolved recently found – to their surprise– that smaller and larger theropod dinosaurs like these didn’t necessarily get that way merely by growing slower or faster.
In a new paper published in Science, “Developmental strategies underlying gigantism and miniaturization ...
