A new study finds that temporary nature-based carbon removal can lower global peak warming levels but only if complemented by ambitious fossil fuel emission reductions.

Researchers have discovered increased levels of of a microRNA in type 2 diabetes, which has a negative effect on insulin secretion. Their experiments on human insulin producing cells in the pancreas also demonstrates that it is possible to increase the…

A team has successfully increased the levels of energy absorbed by wafer-thin photovoltaic panels by 25%. Their solar panels, just one micrometer thick, convert light into electricity more efficiently than others as thin and pave the way to make it eas…

A new study reports that, among youth with substance use and depression, a significant proportion show early improvements in depression during their treatment for substance use. Youth who are using cannabis less frequently prior to treatment and those …

Researchers have created a genome editing technology that allows for slight variations in target DNA but retains local specificity, and which could help realize the potential of CRISPR/Cas-based gene therapy and pathogen diagnosis.

According to the latest assessment report from the Intergovernmental Panel on Climate Change, a considerable reduction in CO2 emissions is required to limit the consequences of climate change. Producing fuel from renewable sources such as waste wood an…

A new approach could cut the time it takes to alter patients’ immune cells for infusion back into the body to find and attack cancer. The cell manufacturing process for this type of immunotherapy that was pioneered at Penn — CAR T cell therapy — typi…

New research is breaking ground in repurposing an FDA-approved drug as a potential treatment in Down syndrome and normal aging. The results suggest that GM-CSF may improve cognitive function in people with Down syndrome. The drug sargramostim (GM-CSF, …

Some people recovering from COVID-19 pneumonia have CT evidence of damage to their lungs that persists a full year after the onset of symptoms, according to a new study.

A newly published study of orb-weaving spiders has yielded some extraordinary results: The spiders are using their webs as extended auditory arrays to capture sounds, possibly giving spiders advanced warning of incoming prey or predators.

Using lessons learned from the eye-imaging technology optical coherence tomography (OCT), engineers have demonstrated a LiDAR system that is fast and accurate enough to potentially improve the vision of autonomous systems such as driverless cars and ro…

Artificial intelligence (AI) is an effective tool for fracture detection that has potential to aid clinicians in busy emergency departments, according to a new study.

Researchers discovered that two distinct classes of fibroblast cells accumulate in pancreatic tumors and play opposing roles to promote and restrain pancreatic cancer growth. Appropriately targeting these cells may offer options to improve treatment ou…

Thanks to avocados’ rise to superfood stardom, there are now more avocado-derived products in the supply chain than ever. In a unique study, researchers looked at the possibility of using avocado meal — the ground, dried, and defatted pulp, seed, and …

Staying well-hydrated may be associated with a reduced risk for developing heart failure. New findings suggest that consuming sufficient amounts of fluids throughout life not only supports essential body functioning but may also reduce the risk of seve…

Researchers have found that dysfunction in an important cell subtype in the brain’s neuronal network contribute to chronic symptoms in the neurodevelopmental disorder Dravet syndrome.

Researchers advocate for a paradigm change in the science of forecasting corrosion damage within reinforced concrete structures. They discuss the severe flaws in using the chloride threshold concept for forecasting corrosion and say change is needed to…

Researchers want to leverage the centuries-old art of cutting paper, kirigami, into designs to develop a sensor sheet that can stretch and breathe with the skin while collecting electrocardiographic data. Scientists in Japan use cuts in a film made of …

Chemotherapy is known for its painful side-effects. It also has limitations when the cancer has metastasized to the lymph nodes. The lymphatic drug delivery system, where anticancer drugs are injected directly into the sentinel lymph nodes under ultras…

A new heat storage material could help to significantly improve the energy efficiency of buildings. It can be used to store surplus heat and release it back into the environment when needed. Unlike existing materials, the new one can absorb significant…
