New insight into how 'tidying up' enzymes work

Researchers have gained insight into how 'tidying up' enzymes, like cytochromes P450, break down drug molecules. The study reveals that the oxygen transfer process can be influenced by three factors: molecular docking, oxygen-accepting ability, and enzyme pocket shape.

What's mine is virtually yours

A study by University of Bristol academics found that virtual MIMO technology can increase data capacity by up to 50% but also makes things worse for some users in certain scenarios. The researchers propose metrics to determine when to use this technology, highlighting the need for careful design and intelligence in the network.

Today's children do engage in active play

Research suggests that actively engaging children in leisure time can boost their physical activity levels. However, the study found that boys and girls have different preferences for active play due to societal pressures. The researchers also noted that boys tend to have more freedom to roam during active play.

Smartphones -- the grip of death

New research from the University of Bristol's Centre for Communications Research investigates how smartphone grips impact wireless signal strength. Holding a device can lead to a 100-fold reduction in sensitivity and signal fluctuations, impairing service quality.

Noise distracts fish from their dinner

A study found that brief exposure to noise playback caused three-spined sticklebacks to make more foraging mistakes and be less efficient in consuming food. The researchers suggest that noise pollution could have a wider range of detrimental effects on fish behavior than previously thought.

When continents formed

Researchers at the University of Bristol have developed a new methodology for calculating model ages of continental crust formation. This approach uses the isotope composition of newly formed crust to estimate age, resulting in significantly younger and more consistent dates than previous methods based on mantle isotopes.

Energy use in the media cloud

Researchers estimate global media consumption will drive 2,570 exabytes of data per year by 2030. To achieve renewable energy infrastructure, a 60-performance improvement in efficiency is needed, potentially reached by 2021. Behaviour change strategies like reducing digital waste and persuasive web design can reduce overall demand.

A speed gun for the Earth's insides

Researchers at the University of Bristol have developed a method to measure the movement of the Earth's deep interior, which controls continents and ocean locations. This technique uses seismic waves to study the properties of a mysterious layer called D″, where the mantle meets the core.

Dogs may be pessimistic too

A new study by the University of Bristol has found that dogs with separation-related behaviors tend to make more pessimistic judgments, suggesting a cognitive bias. The research provides insight into animal emotions and highlights the importance of addressing underlying negative emotional states in dogs.

Screen time linked to psychological problems in children

A study of over 1,000 children found that excessive screen time is related to higher psychological difficulty scores, regardless of physical activity. Children who spent more than two hours per day on screens had better psychological scores, while those with moderate physical activity fared better in certain areas but worse in others.

Life threatening breathing disorder of Rett syndrome prevented

Researchers at the University of Bristol have discovered a way to prevent intermittent episodes of breath holding associated with Rett syndrome by increasing levels of aminobutyric acid and stimulating serotonin receptors. This breakthrough has significant implications for alleviating symptoms in patients with this debilitating disease.

Taking the pulse of coral reefs

Coral reefs are surprisingly noisy places with fish and invertebrates producing clicks and grunts that provide useful information about the state of the reef. Healthier reefs were found to be louder, with a clear association between overall noise level generated and the amount of living coral.

Less is more for a hungry bat

Researchers discovered that the barbastelle bat can catch earless moths by using an unusual whispering strategy. By producing quieter echolocation calls than other bats, the barbastelle can hear unsuspecting moths before they become aware of its presence, giving it an advantage in hunting.

Marine Pied Piper leads Nemo astray

A new study found that short exposure to artificial noise makes fish attracted to inappropriate sounds, putting their survival at risk. The researchers used underwater experiments to show that baby reef fish can learn and remember specific sounds, including those made by humans.

Major step ahead for cryptography

A new encryption scheme developed by Professor Nigel Smart allows for computations to be performed on encrypted data, enabling secure storage and access of sensitive information. This technology has the potential to revolutionize fields such as medical care research and electronic voting, while maintaining patient privacy.

Baby corals dance their way home

Researchers discovered that coral larvae can detect sound waves to locate suitable habitats, which is essential for their survival. The study highlights the importance of understanding how corals respond to their environment, particularly in light of human noise pollution.

Bone-marrow stem cells in MS show promise

A small trial of bone marrow stem cell therapy in patients with MS found the procedure to be well-tolerated and suggested potential benefits. The study's results, published in Clinical Pharmacology and Therapeutics, provide a promising lead for further research into this emerging treatment option.
