AMIHOT II trial data presented at TCT

The AMIHOT II trial found that infusing oxygen-saturated blood into the previously blocked artery after an angioplasty procedure significantly reduced the size of the 'infarct zone', or damaged heart tissue. The study showed a 6.5% reduction in infarct zone size and no significant increase in Major Adverse Cardiac Events at 30 days.

Fewer adverse cardiac events at one year

The SPIRIT III trial found that the Xience V everolimus-eluting coronary stent significantly reduced major adverse cardiac events, including heart attacks and deaths from cardiac causes, by 50% after 12 months compared to the Taxus paclitaxel-eluting stent. This reduction in events is an important finding for patients with heart disease.

Schools not sustaining mental health aid to children displaced by Hurricanes Katrina and Rita

A RAND Corporation study found that many schools in Louisiana, Mississippi, Alabama, and Texas struggled to provide ongoing mental health support to students displaced by the hurricanes. Despite initial efforts, schools often returned to academics-only focus within six months, citing barriers such as lack of resources and staff training.

Research for a better old age

The New Dynamics of Ageing Programme has funded 12 research projects, totaling £3million, to investigate various aspects of ageing. These studies aim to enhance the quality of life, productivity, and self-sufficiency of older adults, with a focus on improving their health, social engagement, and community support.

The difference between fish and humans: scientists answer century-old developmental question

Researchers have discovered a key difference in the way gastrulation occurs between higher vertebrate species and less evolutionarily advanced animals. The study reveals that higher vertebrates acquire a new mechanism of 'cell intercalation' to position their axis at the midline, distinguishing them from fish and other lower vertebrates.

Nanofabrication method paves way for new optical devices

A new fabrication technique using soft lithography has enabled the mass production of plasmonic metamaterials, which exhibit exceptional optical properties due to their unique structure. The technique allows for scalable manufacturing and can produce materials with high-quality transmission behavior, focusing light in microscale patches.

New technology reveals seal behavior

Researchers used sensors attached to 85 seals to track their movements and collect data about the marine environment. The results show that elephant seals adopted different strategies to find food, visiting colder waters nearer the continental shelf.

Music hath charms to probe the brain's auditory circuitry

The study explores how the brain processes musical movements and transitions, finding two distinct networks involved in perceiving these events. The ventral region detects salient events, while the dorsal region focuses attention on event boundaries, forming a tightly coupled network that maintains attention during movement transitions.

Parents seeking sex abandon 1 in 3 offspring

A study published in Journal of Evolutionary Biology found that penduline tit parents frequently abandon 1 in 3 clutches of eggs to pursue new mates. This unique breeding strategy allows for improved reproductive success but also poses risks for the young.

Hidden order found in a quantum spin liquid

Researchers have discovered a hidden magnetic order in a ceramic material that extends over chains of 100 atoms, with potential applications in quantum computing and information processing. The team found that the magnetic excitations can propagate long distances at low temperatures, but can be disrupted by defects or heat.

£2 million dwarfism study launched

An international team of researchers has been awarded £2 million to study the genetic causes of dwarfism and develop future treatments. The EuroGrow project aims to investigate the most common bone disorders that lead to short stature, with a focus on achondroplasia, pseudoachondroplasia, and spondyloepiphyseal dysplasia congenita.
