For The Better

Aerosols carried in wildfire smoke plumes that are hundreds of hours old can still affect climate, according to a new study.

New research highlights disparities in fine particulate matter (PM2.5) trends between American Indian (AI) and non-AI populated U.S. counties. PM2.5 is one of several air pollutants regulated by the U.S. EPA. Downward trends in PM2.5 concentrations wer…

Parkinsonism is a term for a group of neurological conditions that cause movement problems including tremors, slowed movement and stiffness, with Parkinson’s disease being one of the better knowns causes. A new study suggests that older people taking s…

Public health experts have long been concerned by the emergence of so-called ‘superbugs’ — existing bacterial, viral, or fungal pathogens that have evolved to evade the antibiotics, antivirals and antifungals developed to kill them. The scope and seve…

Researchers found that niacin limits Alzheimer’s disease progression when used in models in the lab, a discovery that could potentially pave the way toward therapeutic approaches to the disease.

In-vitro fertilization (IVF) clinics that offer money-back guarantees (MBGs) for their services achieve a higher live-birth success rate with less aggressive treatments than clinics that do not provide money-back guarantees.

Scientists have discovered a new family of helpful proteins in the lung. When stimulated, these bitter taste receptors, called T2Rs, prevent fluid from entering the lung through blood vessels. The findings could pave the way for new treatment for patie…

Pancreatic cancer is notoriously difficult to cure or even treat. Now, a new strategy has succeeded in making pancreatic tumors visible to the immune systems of mice and vulnerable to immune attack, reducing cancer metastases by 87%.

Researchers may have developed long-lived biological computers that could potentially persist inside cells. Researchers forgo the traditional DNA-based approach, opting instead to use the nucleic acid RNA to build computers. The results demonstrate tha…

In a new study, researchers report that a group of cone snails produces a venom compound similar to the protein somatostatin. While they continue to learn more about this venom compound and its possible pharmaceutical applications, the results show the…

One of the great mysteries of late medieval history is why did the Norse, who had established successful settlements in southern Greenland in 985, abandon them in the early 15th century? The consensus view has long been that colder temperatures, associ…

A study in mice and lab-grown cells finds sulforaphane could help prevent and treat illnesses caused by certain coronaviruses, including COVID-19.
