The rate of overdose deaths among U.S. teenagers nearly doubled in 2020, the first year of the COVID pandemic, and rose another 20% in the first half of 2021 compared with the 10 years before the pandemic, even as drug use remained generally stable dur…

Scanning the brains of newborns, researchers have found that maternal exposure to poverty and crime can influence the structure and function of young brains even before babies make their entrances into the world.

Modern methods of creating plant-based meat can yield high optical similarities and targeted molecular-sensory methods, but on a molecular scale, it appears completely different from the food it tries to mimic. Scientists investigate the molecular func…

Vesicles secreted from human heart cells may repair damaged tissue and prevent lethal heart rhythm disorders, according to a new study.

A study indicates that SARS-CoV-2 spreads extensively in households, with children being a significant source of that spread. Approximately 50 percent of household members were infected from the first-infected individual during the study period. Althou…

Silica exposure is a driving force behind rising rates of coal workers’ pneumoconiosis, according to a new study that compared the pathology and mineralogy of the disease across generations. The study offers scientific evidence explaining why progressi…

Collective wisdom dictates that online shoppers gravitate toward the highest-rated products. But new research debunks this and shows top reviews carry more sway in a customer’s final buying decisions when they are comparing products.

An enzyme that can help release phosphorus from its organic forms has been identified.

Researchers have unraveled new secrets behind coronaviruses’ battle plans — providing new insights into how these deadly viruses sometimes win the war against human immune systems. The immunologists have discovered how SARS and MERS proteins block the…

Subarachnoid hemorrhage is a type of bleeding stroke which can lead to a delayed ischemic stroke after just a few days. Researchers have shown that massive electrochemical waves in the brain act as a marker announcing an impending ischemic stroke. Elec…

A new article finds a strong link between the actions of free radicals and free iron in the skin — a link that causes skin to age prematurely after exposure to the sun. The researchers have also identified antioxidants that can be added to skin produc…

Helping green sea turtles suffering with large debilitating tumors may be a simple as sunlight. Turtles with fibropapillomatosis are treated at rehab facilities where the tumors are surgically removed. Many do not survive or the tumors regrow. Research…

Researchers present reasons to assess the effectiveness and safety of vaccines with both conventional and challenge trials and argue that pandemic preparedness should include groundwork for both trial types.

Milling rice to separate the grain from the husks, produces about 100 million tons of rice husk waste globally each year. Scientists searching for a scalable method to fabricate quantum dots have developed a way to recycle rice husks to create the firs…

Researchers have developed a 3D printing technique to fabricate microfluidic devices for biomedical applications at a microscale not previously possible.

While there are no successful non-invasive therapeutics currently available for the treatment of vision loss, researchers at have come up with a new idea to address this growing problem. Currently, ophthalmologists use electronic technology to directly…

Generating power while purifying the environment of greenhouse gases should be achievable using bacteria. Microbiologists have demonstrated that it is possible to make methane-consuming bacteria generate power in the lab.

Medical imaging is an important part of modern healthcare, enhancing both the precision, reliability and development of treatment for various diseases. Artificial intelligence has also been widely used to further enhance the process. However, conventio…

For cancer patients, COVID-19 poses a particular risk due to their often compromised immune systems. Now, a study shows that, due to Omicron, there is an increasing number of breakthrough infections in people with cancer, especially while they are unde…

A research team has developed an innovative technology for in vivo imaging of the important biological processes involved in the injury and repair of spinal cords, paving the way for a better understanding of the pathology and potential treatment of sp…
