Producing ‘green’ energy — literally — from living plant ‘bio-solar cells’

Scientists have turned to photosynthesis to generate current

15-Dec-2022

Though plants can serve as a source of food, oxygen and décor, they’re not often considered to be a good source of electricity. But by collecting electrons naturally transported within plant cells, scientists can generate electricity as part of a “green,” biological solar cell. Now, researchers ...

Drug discovery and development — in space?

The low-gravity environment could speed up the development and discovery of complex molecules used in medicines

21-Nov-2022

Carrying out scientific experiments in space allows scientists to study and make drugs without gravity, which can lead to surprising results that improve research back on Earth. According to a cover story in Chemical & Engineering News, an independent news outlet of the American Chemical Society, ...

Artificial intelligence against hair loss?

AI helps researchers design microneedle patches that restore hair in balding mice

09-Nov-2022

Hair loss is undesirable for many men — and women — because one’s hairstyle is often closely tied to their self-confidence. And while some people embrace it, others wish they could regrow their lost strands. Now, researchers reporting in ACS’ Nano Letters have used artificial intelligence (AI) to ...

Biosensor detects brain tumors with less than a drop of blood

30-Sep-2022

Despite significant advances, mortality from brain tumors remains high with five-year survival rates of 36%, according to the National Cancer Institute. More accurate diagnoses might improve the situation, but tissue biopsies are invasive and can miss important information about a tumor’s ...

Nanoplastics can disrupt human liver, lung cells’ processes in lab experiments

What happens when people unknowingly eat, drink or inhale nearly invisible pieces of plastic?

20-Sep-2022

Although it’s unclear what impact this really has on humans, researchers have now taken a step toward answering that question. In ACS’ Environmental Science & Technology, a team reports laboratory results indicating that tiny plastic particles could enter liver and lung cells and disrupt their ...

Detecting nanoplastics in the air

“Nanoplastics are a major concern if they’re in the air that you breathe, getting into your lungs and potentially causing health problems”

29-Aug-2022

Large pieces of plastic can break down into nanosized particles that often find their way into the soil and water. Perhaps less well known is that they can also float in the air. It’s unclear how nanoplastics impact human health, but animal studies suggest they’re potentially harmful. As a step ...

Food allergies can be reversed in mice by targeting the microbiome

23-Aug-2022

Although many people with dietary allergies experience mild symptoms when exposed to triggering foods, some face potentially fatal consequences. A bacterial compound called butyrate that’s made by healthy microbiomes has shown promise against allergic reactions in lab tests, but it’s nasty to ...

New drug candidate fights off more than 300 drug-resistant bacteria

16-Aug-2022

Urinary tract infections are common, yet are increasingly tough to treat because the bacteria that cause them are becoming resistant to many antibiotics. Now, in ACS Central Science, researchers report a new molecule that inhibits drug-resistant bacteria in lab experiments, as well as in mice ...

Lager beer, whether it contains alcohol or not, could help men’s gut microbes

17-Jun-2022

Like wine, beer can have health benefits when consumed in moderation. Non-alcoholic beers have become wildly popular recently, but are these drinks also healthful? In a pilot study, researchers in ACS’ Journal of Agricultural and Food Chemistry report that compared to their pre-trial microbiome, ...

Edible, fluorescent silk tags can suss out fake medications

The codes within the tags can be read by a smartphone app

20-Apr-2022

Recent developments such as the explosion of online pharmacies and supply chain issues have made it easier for counterfeiters to profit from fake or adulterated medications. Now, researchers reporting in ACS Central Science have created edible tags with fluorescent silk proteins, which could be ...
