Researchers invent soft, bioelectronic sensor implant

14 January 2025 at 23:17
Scientists describe their construction of complementary, internal, ion-gated, organic electrochemical transistors that are more amenable chemically, biologically and electronically to living tissues than rigid, silicon-based technologies. The medical device based on these transistors can function in sensitive parts of the body and conform to organ structures even as they grow. The result is a biocompatible sensor that can monitor brain functions in pediatric patients as they develop and grow.

Gene editing extends lifespan in mouse model of prion disease

14 January 2025 at 23:17
Researchers have developed a gene-editing treatment for prion disease that extends lifespan by about 50 percent in a mouse model of the fatal neurodegenerative condition. The treatment, which uses base editing to make a single-letter change in DNA, reduced levels of the disease-causing prion protein in the brain by as much as 60 percent. The work demonstrates that lowering levels of the prion protein improves lifespan in animals that have been infected with a human version of the protein.

Ecologist highlights critical gaps in global wildlife trade monitoring

14 January 2025 at 17:54
Using 22 years of LEMIS data, a recent study explores the dimensions of wildlife trade and obtain one of the most comprehensive overviews to date. The study reveals striking findings: between 2000 and 2022, the US traded almost 30,000 wild species and over 2.85 billion individuals, with over 50% of individuals from most taxa sourced directly from the wild. These findings are significant as the impact of trade on most of these species has never been assessed.

Hearing impairment may be a sign of increased risk of Parkinson's disease

14 January 2025 at 17:52
There may be a link between hearing impairment and an increased risk of developing Parkinson's according to new research. This is one of the first studies to examine whether sensory impairments, such as hearing loss, might increase the risk for Parkinson's or serve as an early warning sign. Parkinson's UK reports that an estimated 153,000 people in the UK currently live with Parkinson's, which is the fastest-growing neurological condition in the world.

Great Barrier Reef fish evidence suggests shifts in major global biodiversity patterns

14 January 2025 at 17:52
Life on the Great Barrier Reef is undergoing big changes in the face of climate change and other human-caused pressures, a new study reveals. From food security to controlling seaweed and even making sand for beaches, reef fish are a hugely important part of marine ecosystems providing a range of benefits to humans and coral reef ecosystems. New research reveals significant transformations in fish communities on the Great Barrier Reef, the World's largest coral reef ecosystem.

Genetic tweak optimizes drug-making cells by blocking buildup of toxic byproduct

14 January 2025 at 17:52
Scientists have developed a new strategy to enhance pharmaceutical production in Chinese hamster ovary (CHO) cells, which are commonly used to manufacture protein-based drugs for treating cancer, autoimmune diseases and much more. By knocking out a gene circuit responsible for producing lactic acid -- a metabolite that makes the cells' environment toxic -- researchers eliminate a primary hurdle in developing cells that can produce higher amounts of pharmaceuticals like Herceptin and Rituximab, without compromising their growth or energy production.

SCP-Nano: A new technology to visualize nanocarriers in cells and tissues

14 January 2025 at 17:51
How can we ensure that life-saving drugs or genetic therapies reach their intended target cells without causing harmful side effects? Researchers have taken an important step to answer this question. They have developed a method that, for the first time, enables the precise detection of nanocarriers -- tiny transport vehicles -- throughout the entire mouse body at a single-cell level.

Hepatitis E vaccination is effective in an epidemic

14 January 2025 at 17:51
Hepatitis E, a potentially serious viral liver disease, is transmitted through contaminated water. The risk is particularly high in populations with limited access to safe water and sanitation. In South Sudan, outbreaks have regularly ravaged camps for internally displaced persons and their host populations. Although a vaccine has been available since 2011, its 3-dose regimen makes it difficult to administer in such a context.

New training technique for highly efficient AI methods

14 January 2025 at 17:51
AI applications like ChatGPT are based on artificial neural networks that, in many respects, imitate the nerve cells in our brains. They are trained with vast quantities of data on high-performance computers, gobbling up massive amounts of energy in the process. Spiking neurons, which are much less energy-intensive, could be one solution to this problem. In the past, however, the normal techniques used to train them only worked with significant limitations. A recent study has now presented a possible new answer to this dilemma, potentially paving the way for new AI methods that are much more energy-efficient.

Direct discharge electrical pulses for carbon fiber recycling

14 January 2025 at 17:51
Carbon fiber-reinforced polymers (CFRPs) are used in the aerospace, automotive, and sports equipment industries. However, their recycling remains a major problem. In a recent study, researchers demonstrated a novel direct discharge electrical pulse method for the efficient, effective, and environmentally friendly separation of CFRPs to recover high-quality carbon fibers. This work is expected to pave the way for a more sustainable world.
