Cannabinoid CBG reduces anxiety and stress in first human clinical trial
A lesser-known cannabinoid that is gaining in popularity Cannabigerol (CBG) effectively reduced anxiety in a clinical trial without the intoxication typically associated with whole plant cannabis. It may even have some memory enhancing effects, according to a new study. For the study, researchers conducted the first human clinical trial investigating the acute effects of CBG on anxiety, stress and mood. The research revealed that 20 mg of hemp-derived CBG significantly reduced feelings of anxiety at 20, 45 and 60 minutes after ingestion compared to a placebo.

Surprising finding in glioblastomas
Glioblastomas are highly aggressive, usually incurable brain tumors. If all therapeutic options are exhausted, patients have an average life expectancy of less than two years. Now researchers have made a surprising discovery: in the vicinity of glioblastomas, they found islands of highly potent immune cells in the neighboring bone marrow of the skull, which play a central role in defending against cancer. The new data may open up prospects for innovative therapies. On the other hand, they cast a shadow over conventional strategies.

What's the weather like in the deep sea?
A new study has revealed how even the deepest seafloors are affected by the daily back-and-forth of the tides, and the change of the seasons, and that currents at the bottom of the ocean are far more complicated than previously thought. These findings are helping us understand the deep-sea pathways of nutrients that support important deep-sea ecosystems, assess where microplastics and other pollutants accumulate in the ocean, and reconstruct past climate change.
Researchers explore the potential of clean energy markets as a hedging tool
Clean energy investments offer potential stability and growth, especially during volatile market conditions. A recent study explored the relationship between clean energy markets and global stock markets. Significant spillovers were observed from major indices like the SP500 to markets such as Japan's Nikkei225 and Global Clean Energy Index. These interactions suggest opportunities for optimizing investment portfolios and leveraging clean energy assets as hedging tools in volatile market environments.
Most blood thinner dosing problems happen after initial prescription
More than two-thirds of people taking blood thinners take direct oral anticoagulants, or DOACs, which are under- or over-prescribed in up to one in eight patients. A new study finds that most prescribing issues for DOACs occur after a provider writes the initial prescription. Researchers say the findings highlight why patients on DOACs need to be monitored consistently.

They describe that the so-called callyaerins act against the infectious disease by employing a fundamentally different mechanism compared to antibiotic agents used to date.
Improving Alzheimer's disease imaging -- with fluorescent sensors
Neurotransmitter levels in the brain can indicate brain health and neurodegenerative diseases like Alzheimer's. However, the protective blood-brain barrier (BBB) makes delivering fluorescent sensors that can detect these small molecules to the brain difficult. Now, researchers demonstrate a way of packaging these sensors for easy passage across the BBB in mice, allowing for improved brain imaging. With further development, the technology could help advance Alzheimer's disease diagnosis and treatment.
A coating of solar cells with special organic molecules could pave the way for a new generation of solar panels. This coating can increase the efficiency of monolithic tandem cells made of silicon and perovskite while lowering their cost -- because they are produced from industrial, microstructured, standard silicon wafers.
Strong El Nino makes European winters easier to forecast
Forecasting European winter weather patterns months in advance is made simpler during years of strong El Ni o or La Ni a events in the tropical Pacific Ocean, a new study has found.
Physicists use light to probe deeper into the 'invisible' energy states of molecules
Physicists have experimentally demonstrates a novel physical effect that was predicted 45 years ago. The effect will result in a new chemical analysis technique, to simultaneously identify molecular bonds and their 3D arrangement in space. This new technique will find applications in pharmaceutical science, security, forensics, environmental science, art conservation, and medicine.

Green hydrogen: 'Artificial leaf' becomes better under pressure
Hydrogen can be produced via the electrolytic splitting of water. One option here is the use of photoelectrodes that convert sunlight into voltage for electrolysis in so called photoelectrochemical cells (PEC cells). A research team has now shown that the efficiency of PEC cells can be significantly increased under pressure.
Key challenges and promising avenues in obesity genetics
Research on the genetics of obesity dates to the early 1920s, with many of the initial findings indicating the complexity and multifaceted nature of obesity perfectly resonating with more modern discoveries. Researchers have collected nearly a century's worth of considerations and advancements to frame their perspectives on modern research into the genetics of obesity.

Recent volcanic 'fires' in Iceland triggered by storage and melting in crust
Scientists have detected geochemical signatures of magma pooling and melting beneath the subsurface during the 'Fagradalsfjall Fires', that began on Iceland's Reykjanes peninsula in 2021. Samples show that the start of the eruption began with massive pooling of magma, contrasting initial hypothesis for magma ascent straight from the mantle.

Gut microbes implicated in bladder cancer
Bladder cancer is the tenth most common type of cancer worldwide and is often linked to exposure to harmful chemicals, such as those found in tobacco smoke. A new study shows that the bacteria in our guts may play an important role in bladder cancer development. The scientists showed experimentally that certain gut bacteria can transform a class of carcinogens, often found in cigarette smoke, into related chemicals that accumulate in the bladder and give rise to tumors.
Unraveling a key junction underlying muscle contraction
Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal kingdom and setting the stage for possible future treatments for muscular disorders.
For bigger muscles push close to failure, for strength, maybe not
When lifting weights, do you wonder how pushing yourself to the point of failure -- where you can't do another rep -- impacts your results? New research finds that if you're aiming for muscle growth, training closer to failure might be more effective. It doesn't matter if you adjust training volume by changing sets or reps; the relationship between how close you train to failure and muscle growth remains the same. For strength, how close you push to failure doesn't seem to matter as much.

Study finds genetic variant among people who experience a rare recovery from ALS
Though exceedingly rare, some people diagnosed with amyotrophic lateral sclerosis (ALS) partially or fully recover from the lethal neurodegenerative disease. A better understanding of this baffling phenomenon, reported in medical literature for at least 60 years, could point to potential new treatment approaches. To that end, researchers launched a study of ALS recovery patients and found certain genetic factors that appear to protect against the disease's typical assault on motor neurons.
