Bionic nerves to battle wasting muscle

Researchers have developed tiny implants, called BIONs, that can be injected into muscles to stimulate them and prevent wasting. The implants use radio signals to activate electrical stimuli, offering a potential breakthrough in treating stroke patients who are at risk of serious complications such as thrombosis and muscle dislocation.

Does Hale-Bopp have a moon?

Astronomers discovered a potential satellite orbiting Comet Hale-Bopp using Hubble Space Telescope images. Sekanina's model suggests a 33-kilometre-wide moon about 200 kilometres from the comet's nucleus.

Early planet formation triggers planet offspring

Researchers found that massive planets can trigger the formation of additional planets through violent processes, leading to a different-looking system. The study suggests an upper limit to planetary growth due to unstable conditions, raising questions about the possibility of habitable Earth-like planets in such environments.

MIT researchers 'amplify' atoms

MIT researchers have developed XenoMouse technology, which enables the amplification of atoms for genomics-based antibody drug development. This breakthrough could lead to the creation of fully human monoclonal antibody drugs with high affinity and reduced side effects.

Meet the chemical that lets sea creatures thrive

Deep-sea animals have higher concentrations of trimethylamine oxide (TMAO), a compound that helps proteins withstand high pressures and misfolded proteins. TMAO's protective power extends beyond sea creatures to humans, with potential applications in cystic fibrosis treatment.

Products must be essential to patient care

The American College of Physicians recommends that physicians only sell products from their offices if they are clinically relevant to the patient's condition. The guidelines emphasize transparency and disclose financial interests in products, ensuring patients have access to alternative options and reasonable charges.

Cranfield professor receives top safety award

Professor Helen Muir has received the Whittle Safety Award for her pioneering work on passenger behaviour in emergencies, significantly improving air travel safety. Her research and contributions have been widely recognized globally, with Vice-Chancellor Prof. Frank Hartley praising her achievements.

Post-traumatic stress disorder may follow traffic crashes, according to doctors at The Children's Hospital of Philadelphia

A recent study published in Pediatrics found that even minor injuries from traffic crashes can lead to post-traumatic stress disorder (PTSD) in children. The study, conducted at The Children's Hospital of Philadelphia, analyzed 102 patients between the ages of 3 and 18 who were involved in traffic-related incidents.

Genetic extremism overstates risks

A group of Oregon State University scientists emphasize the potential benefits of genetic engineering in forestry, including faster-growing trees that can reduce the burden on native forests. They argue against 'genetic extremism' and call for a more careful analysis of the issues based on science.

Explaining how ozone "chokes up" plants

Researchers identified how ozone 'chokes up' plants by directly affecting guard cells, inhibiting stomatal opening and reducing photosynthesis. This knowledge may lead to breeding or genetically engineering less ozone-sensitive plant varieties to improve productivity in regions with high ozone exposure.

Feeding the world by cleaning the air: study ties heavy regional haze to reductions in China's crop production

A new study suggests that cleaning up air pollution in China could increase crop production by up to one-third. Heavy regional haze scatters and absorbs solar radiation, reducing plant growth and food production. Researchers estimate that China loses around 10-30% of its crop production to haze.

Poverty impacts mental development of children exposed to cocaine before birth

Research suggests that poverty has a greater impact on the mental development of children exposed to cocaine before birth, even when controlling for IQ scores and preschool attendance. Children who had been exposed to cocaine performed no worse than low-income children without cocaine exposure in problem-solving tests.

Americans trust each other less, but still trust institutions

Research at Ohio State University found that Americans' trust in individuals has declined by about 10% between 1975 and 1994, with a decline of half a percent per year. Despite this, trust in institutions such as government, religion, and education remained stable, and people maintained their involvement in clubs and organizations.

Eating margarine with Stanol lowers cholesterol by 10 percent

A new study found that consuming three servings of a margarine-like spread containing stanol can lower total and low-density lipoprotein cholesterol levels by up to 10%. The study, which involved over 300 participants with mildly elevated cholesterol levels, showed no adverse effects from using the fortified margarine.

Researchers discover cause of a human immunodeficiency

A team of scientists has discovered that a lack of the B cell linker protein (BLNK) is responsible for an immunodeficiency in mice and a young man with recurring bacterial infections. The study reveals that BLNK plays a crucial role in B lymphocyte development, leading to impaired immune function.

Behind the mask

Researchers at Princeton University developed a new patterning technology called Lithographically Induced Self Assembly (LISA), which creates arrays of ultrasmall pillars without the need for a carefully engineered mask. The technique has potential applications in computer memory chips, flat-panel displays, and DNA sorting.

Waste not

The US Navy is developing a new system to treat non-oily wastewater from its vessels, eliminating costs and fines associated with discharging wastewater. The Aerated Non-Oily Wastewater Membrane Treatment System (AMTS) has shown promise in treating graywater and vacuum-collected sewage, allowing ships to remain on their stations longer.

If you think so it will happen

Researchers are decoding neural activity to translate brain signals into prosthetic limb movements, potentially empowering paralyzed patients to regain control. The technology involves implanting electrodes in the brain and using computer algorithms to interpret neural patterns.
