New study uncovers the interaction of calcium channels

A research team led by Professor Byung-Chang Suh has observed the dynamic combination of alpha 1 and beta subunits in calcium channels, revealing competitive replacement and stability. This breakthrough enables precise control of calcium ion inflow inside cells and opens a new horizon for treating high blood pressure and brain diseases.

Researchers develop new devices to test retinal cells

Researchers developed two new devices to mechanically stress human retinal cells, mimicking slow and continuous stress levels as well as high levels of stress. The study found that mechanical stress results in the expression of vascular endothelial growth factor, a protein linked to disease initiation and progression.

Peptide engineered by NTU Singapore successfully exploits Achilles' heel of Zika virus

Scientists at NTU Singapore have engineered an antiviral peptide that exploits the Zika virus' viral membrane, reducing disease symptoms and deaths in infected mice. The peptide can cross the blood-brain barrier to tackle viral infection in mouse brains, a critical feature since Zika targets the brain and central nervous system.

'Cellular dust' provides new hope for regenerative medicine

Extracellular vesicles, or 'cellular dust', have shown therapeutic properties similar to stem cells without their disadvantages. These gel-like vesicles can be produced by a single donor for several patients and have demonstrated potential in repairing heart, liver, and kidney lesions.

Plump songbirds more likely to survive migration over Gulf of Mexico

A new study provides the first survival estimates for small migratory birds crossing the Gulf of Mexico, revealing that fatter birds and stronger tailwinds significantly increase their chances of survival. By understanding these factors, conservation efforts can be implemented to improve birds' ability to cross the Gulf.

Drug improves survival in metastatic breast cancer

A phase III clinical trial found that palbociclib improves overall survival in women with hormone receptor-positive metastatic breast cancer. The drug, used in combination with standard treatment, led to a clinically meaningful improvement in median overall survival, even in patients who showed sensitivity to prior hormone therapy.

Ice-age climate clues unearthed

A new computational model, PRYSM, has been developed to interpret climate data from lake sediments, revealing that lake temperature proxies underestimated air temperature changes. The model is designed to compare paleoclimate data with climate model simulations, aiming to improve interpretations of past climate changes.

Flu virus could evolve resistance to pandemic drug

A recent study by Imperial College London suggests that the flu virus can develop resistance to favipiravir, a potential pandemic drug, if it undergoes two specific genetic mutations. This finding highlights the need for close monitoring and surveillance to prevent the emergence of resistant strains.

Cannabis pain relief without the 'high'

A team of scientists at McGill University Health Centre has identified the effective dose of cannabidiol (CBD) for safe pain relief without the risk of addiction or euphoria. The study found that low doses of CBD alleviate both pain and anxiety in animal models of chronic pain, offering a potential alternative to THC and opioids.

Data does the heavy lifting: Encouraging new public health approaches to promote the health benefits of muscle-strengthening exercise (MSE)

A new study in the American Journal of Preventive Medicine reports that most US adults do not engage in muscle-strengthening exercise (MSE), with nearly 60% doing no MSE at all. The investigation found that low-to-moderate frequency of MSE is linked to fewer reported health conditions such as diabetes, obesity, and cancer.

New nurses with bachelor's degrees feel better prepared than nurses with associate degrees

A new study by NYU Rory Meyers College of Nursing found that nurses with bachelor's degrees report being better prepared in quality and safety measures, but the gap in preparedness between associate and bachelor's degree nurse graduates has doubled since 2007. This highlights the need for increased educational attainment among new nurs...
