A study is outlining strategies that should be employed by cannabis growers to mitigate the plant’s ability to absorb heavy metals from soil. The study indicates it is possible cannabis contaminated with heavy metals could lead to chronic diseases.

Currently, most diabetics have to check their blood glucose levels by performing finger-prick blood tests, or via implanted sensors. An experimental new device, however, could someday do the job while simply adhered to the surface of the user's skin.

While implanted artificial teeth do offer a longer-term alternative to dentures, they may need to be surgically replaced if gum infections occur. Scientists are thus working on a better implant, that would generate electricity via mouth movements.

Scientists have demonstrated a new type of lithium-battery they say is built specifically for eVTOL flight, leveraging an innovative high-temperature charging technology to give it enough juice for meaningful aerial trips in just five to 10 minutes.

According to Pennsylvania State University's Asst. Prof. Long He, the mushroom-farming industry is currently experiencing a labor shortage. His team has thus set about addressing that problem, by developing a mushroom-picking robot.

With a view to one day developing transparent solar cells that can double as windows in homes and other buildings, an international team of scientists has demonstrated a new type of transparent electrode that can function as a key building block.

Scientists have developed a new way to patch up injuries by 3D printing both hard and soft tissues at the same time, using two different “bioinks.” In tests on rats, the team was able to repair holes in the skulls and skin of the rodents in minutes.

Antibiotic-resistant bacteria are an urgent public health threat. A new single-dose drug has been developed that works on a different mechanism to most antibiotics, and tests in mice show that it can be used to treat multi-drug-resistant gonorrhea.

Researchers at Pennsylvania State University studying an approved anti-depressant drug have found it can interfere in the chain of events leading to osteoarthritis, halting its progress and even promoting the regeneration of cartilage.

In 2019, we looked at an innovative battery for electric vehicles that could be charged in 10 minutes. The researchers behind it have now added a couple more desirable attributes, including a cost they say is on par with internal combustion engines.

Engineers at Penn State University have developed a new type of flexible cement they say can be used to contain methane leaks, by being fed into the the very fine gaps around deteriorating gas wells that traditional cements are unable to fill.

Decades of overuse means bacteria are quickly developing resistance to antibiotics. A new study has found that an FDA-approved drug can act as an "anti-antibiotic,” reducing the development of drug resistance when taken alongside an antibiotic.
