Carbon offsets from forest conservation projects have been overestimated

A new analysis reveals that emission reductions from REDD+ programs have been overestimated, with most projects failing to significantly reduce deforestation. The study found that only a subset of projects have made substantial contributions to climate change mitigation, and many more credits are available than their actual value.

BU researchers describe rebuilding, regenerating lung cells

Researchers from the Center for Regenerative Medicine at Boston University School of Medicine have discovered a novel approach for engrafting engineered cells into injured lung tissue. They successfully reconstituted the stem cell compartment of injured airways and alveoli using cells engineered from pluripotent stem cells, resulting i...

FDA approving drugs after fewer trials, providing less information to public, OSU studies find

A recent study found that the FDA approved 65% of novel drugs in 2022 based on a single clinical trial, while only half of the available studies were classified as randomized clinical trials. This lack of transparency raises concerns about the completeness of the approval process and patient access to accurate information.

The swansong of African hydropower?

New study finds that up to 67% of future hydropower plants in Africa may not be worth the investment due to economic competition with solar and wind power. However, some new hydropower plants could still provide cheap power in the short-term and help integrate solar and wind energy.

High drug price associated with decreased treatment retention for patients with chronic liver disease

A study by researchers at the University of Minnesota Medical School found that high costs for hepatic encephalopathy treatment are associated with decreased treatment retention among patients. Patients who are younger and have metastatic cancer or depression are more likely to skip their medication.

Community-based services could reduce the risk of frailty in older adults with low care needs

Research finds that community-based adult day services can reduce the risk of frailty among older adults by 40%, while home-based personal assistance services have no significant effect. This study suggests that active community engagement may help maintain independence and prevent frailty in older adults.

Sweet corn yield at the mercy of the environment, except for one key factor

A new study by the University of Illinois and USDA-Agricultural Research Service has identified the key factors influencing sweet corn yield. The analysis found that seed source is a significant variable, with processors having a choice over which hybrids to use, and high nighttime temperatures also impact yield.

Severe COVID-19 survivors may show increased vascular risk associated with stress

Researchers found that severe COVID-19 survivors exhibit elevated muscle sympathetic nerve activity in response to mental stress, which accelerates heartbeat and increases blood pressure. This exaggerated reaction, combined with impaired vasodilation, poses a significant risk for cardiovascular complications.
