Researcher creates cell lines to help treat mitochondrial diseases in children

Science Daily - 15/07/2021
The mitochondrion has garnered quite the reputation for its role as the 'powerhouse of the cell.' These tiny, but mighty organelles play various life-sustaining roles, from powering our own cells and organs to fueling chemical and biological processes. But when they aren't working properly, a number of rare diseases can occur.

Fluorescence lighting helps detect impurities in water

Science Daily - 15/07/2021
Shining a beam of light into potentially contaminated water samples may hold the key to real-time detection of hydrocarbons and pesticides in water. Researchers are testing the use of fluorescence to monitor water quality. The results, they say, show great promise.

Repairs using light signals

Science Daily - 15/07/2021
Repairing complex electrical appliances is time consuming and rarely cost-effective. The working group has now developed a smart microparticle that enables defective components in these appliances to be identified more quickly and easily by using light signals. In the long-term, this could make repairs easier and extend the operating life of devices.

Hope for psychosis sufferers

Science Daily - 15/07/2021
Scientists have opened the door to improved treatment of brain dysfunction which causes psychosis.

Thinking without a brain

Science Daily - 15/07/2021
If you didn't have a brain, could you still navigate your surroundings? Thanks to new research on slime molds, the answer may be 'yes.' Scientists discovered that the brainless Physarum polycephalum uses its body to sense mechanical cues in its environment, and decides where to grow based on that information. This finding provides a model for understanding different types of cognition, including our own.

Study shows strong association between perceived risk, availability and past-year cannabis use

Science Daily - 15/07/2021
Combined perceptions of the risk and availability of cannabis influence the risk of cannabis use more than perceived risk and perceived availability alone, according to a new study. Researchers observed that those who perceived cannabis as low-risk and available were more likely to report using the drug in the past year and almost daily compared to those individuals who perceived cannabis as high-risk and unavailable. This is the first study to consider the joint effects of perceived risk and perceived availability.

Heart problems resolve in majority of kids with COVID inflammatory syndrome, study finds

A new avenue for fighting drug-resistant bacteria

Science Daily - 15/07/2021
A small regulatory RNA found in many problematic bacteria, including Escherichia coli, appears to be responsible for managing the response of these bacteria to environmental stresses. Researchers see a promising avenue for more effective treatment of antibiotic-resistant bacteria.

Pandemic of antibiotic resistance is killing children in Bangladesh, researchers find

Pneumonia is the leading cause of death in children worldwide. A new study identifies an unusual pattern of deadly bacteria with resistance to all standard antibiotic therapy in children with pneumonia in Bangladesh. The findings signal an emerging pandemic of fatal antibiotic resistance.

Ultra-processed food linked to higher risk of IBD

Science Daily - 15/07/2021
A higher intake of ultra-processed food is associated with higher risk of inflammatory bowel disease (IBD), finds a new study.

New study suggests benefit-to-harm balance of statins for healthy adults 'generally favorable'

Science Daily - 15/07/2021
Statins are associated with a small increased risk of side effects in patients without a history of heart disease, but these effects are mild compared with the potential benefits of treatment in preventing major cardiovascular events, say researchers.

'Neuroprosthesis' restores words to man with paralysis

Science Daily - 15/07/2021
Researchers have successfully developed a 'speech neuroprosthesis' that has enabled a man with severe paralysis to communicate in sentences, translating signals from his brain to the vocal tract directly into words that appear as text on a screen.

Dogs may not return their owners' good deeds

Science Daily - 15/07/2021
Domestic dogs show many adaptations to living closely with humans, but they do not seem to reciprocate food-giving according to a new study.

Think about this: Keeping your brain active may delay Alzheimer's dementia 5 years

Science Daily - 15/07/2021
Keeping your brain active in old age has always been a smart idea, but a new study suggests that reading, writing letters and playing card games or puzzles in later life may delay the onset of Alzheimer's dementia by up to five years.

Have you ever wondered how many species have inhabited the Earth?

Scientists and engineers have devised a new method for making urea that is more environmentally friendly than today's process and produces enough to be competitive with energy-intensive industrial methods.

Roadless forests see more blazes and greater severity, but fire resilience is the result

Science Daily - 15/07/2021
Roadless national forests in the American West burn more often and at a slightly higher severity than national forests with roads, but the end result for the roadless forests is greater fire resilience, researchers say.

The delicate balance of protecting river deltas and society

Science Daily - 15/07/2021
