Solar cells are vital for the green energy transition. They can be used not only on rooftops and solar farms but also for powering autonomous vehicles, such as planes and satellites. However, photovoltaic solar cells are currently heavy and bulky, making them difficult to transport to remote locations off-grid, where they are much needed.

In a collaboration led by Imperial College London, alongside researchers from Cambridge, UCL, Oxford, Helmholtz-Zentrum Berlin in Germany, and others, researchers have produced materials that can absorb comparable levels of sunlight as conventional silicon solar cells, but with 10,000 times lower thickness.

The material is sodium bismuth sulfide (NaBiS₂), which is grown as nanocrystals and deposited from solution to make films 30 nanometers in thickness. NaBiS₂ is comprised of nontoxic elements that are sufficiently abundant in the earth’s crust for use commercially. For example, bismuth-based compounds are used as a nontoxic lead replacement in solder, or in over-the-counter stomach medicine.

Engineers at RMIT University have developed a method to use disposable personal protective equipment (PPE) to make concrete stronger, providing an innovative way to significantly reduce pandemic-generated waste.

The RMIT team is the first to investigate the feasibility of recycling three key types of PPE—isolation gowns, face masks and rubber gloves—into concrete.

Published in the journals Case Studies in Construction Materials, Science of the Total Environment and Journal of Cleaner Production, the studies by RMIT School of Engineering researchers demonstrate the potential for PPE to be used as reinforcement materials in structural concrete.

Researchers at Washington University School of Medicine in St. Louis have found a new druggable pathway that potentially could be used to help prevent Alzheimer’s dementia.

Amyloid beta accumulation in the brain is the first step in the development of Alzheimer’s dementia. Scientists have poured countless hours and millions of dollars into finding ways to clear amyloid away before cognitive symptoms arise, with largely disappointing results.

In this study, published Aug. 24 in the journal Brain, researchers found a way to increase clearance of waste products from the brains of mice by ramping up a genetic quirk known as readthrough. This same strategy also may be effective for other neurodegenerative diseases characterized by the buildup of toxic proteins, such as Parkinson’s disease, the researchers said.

Life science continued dominating the research schedule aboard the International Space Station on Wednesday to benefit humans living on and off the Earth. The seven Expedition 67 orbital residents explored how living in microgravity affects tissue regeneration, crew psychology, and the human digestion system.

Learning to heal wounds in space is critical as NASA and its international partners plan crewed missions to the Moon, Mars, and beyond. Four station astronauts have been partnering together this week for the skin healing study taking place inside the Kibo laboratory module. Flight Engineers Kjell Lindgren, Bob Hines, and Jessica Watkins, all from NASA, with Samantha Cristoforetti of ESA (European Space Agency), are studying surgical techniques such as biopsies, suture splints, and wound dressing, inside Kibo’s Life Science Glovebox.

Scientists on Earth seek to identify the molecular mechanisms that occur during tissue regeneration in weightlessness. Observations may offer advanced therapies and provide insights into how space-caused accelerated skin aging affects an astronaut’s healing properties. The biomedical experiment may also contribute to better wound healing techniques on Earth.

The number of vulnerability disclosures impacting extended internet of things (XIoT) devices increased by 57% in the first half of 2022 compared to the previous six months, according to a new report by Team82, the research team of cyber-physical systems (CPS) security firm Claroty.

The research also found that vendor self-disclosures increased by 69%. This would be a first for the industry, which usually relies more for disclosures on independent research teams. According to Team82, the trend indicates that more operational technology (OT), IoT, and internet of medical things (IoMT) vendors are establishing vulnerability disclosure programs and dedicating more resources to them.

Additionally, fully or partially remediated firmware vulnerabilities increased by 79% over the same time period, a significant improvement considering the relative challenges in patching firmware versus software vulnerabilities.

The Tasmanian devil may hold the key to cancer immunity especially if we use crispr to edit it into our dna.

Evidence suggests newly evolved genes protect the iconic marsupials against devil tumor facial disease.

Talking about some of the ideas and philosophy surrounding life extension technologies. Our own psychology and coping mechanisms that view death as a good thing. The same way we used to see some diseases as a part of a gods plan. As soon as we cured these diseases, somehow they were not a part of gods plan anymore. The same will happen with aging and death, and that is just a matter of time. Picking apart some of the ways of thinking that suggest a longer life would be a boring or bad thing. We live for all of the pleasant and amazing experiences that we can have in the world, what else could possibly matter more. The end and absence of meaning (death) does not give life meaning. It is life that gives life meaning.

In order to bridge the gap between AI researchers and medical professionals we developed a very accessible free prototype system which can be used by medical professionals to understand the reality of Deep Learning tools for chest X-ray diagnostics.

“I believe we can train the algorithm not only to picture accurately a face you’re looking at, but also any face you imagine vividly, such as your mother’s,” explains Dado.

“By developing this technology, it would be fascinating to decode and recreate subjective experiences, perhaps even your dreams,” Dado says. “Such technological knowledge could also be incorporated into clinical applications such as communicating with patients who are locked within deep comas.”
