Standing up for athletes at risk

Tel Aviv University's Dr. Sami Viskin has developed a new test to detect 'sudden death syndrome' in young athletes, which can be done at the patient's bedside using an electrocardiogram (ECG). The test detects a measurable difference in heart rate called the QT interval, which can help doctors identify patients at risk for sudden death.

DFG establishes 4 new research units

The Deutsche Forschungsgemeinschaft (DFG) has approved four new research units focused on novel synthesis methods in chemistry, quantum diamonds, minimally invasive surgical procedures in medicine, and economic mechanisms in firms and markets. The Research Units will receive a total of 10.2 million euros over three years.

Antidepressants may not improve all symptoms of depression, UT Southwestern researchers find

Researchers analyzed data from the largest study on depression treatment, finding that even responders experience residual symptoms like insomnia and decreased concentration. The study suggests a need for more targeted antidepressant therapies to decrease depressive symptoms and understand their association with concentration.

Giant tortoises show rewilding can work

The introduction of Aldabra tortoises on the island of Mauritius has successfully dispersed ebony seeds, aiding the recovery of a critically endangered tree species. This rewilding experiment demonstrates the potential for restoring extinct interactions in ecosystems.

What do you know about that fracture?

A recent study by American Academy of Orthopaedic Surgeons highlights the lack of knowledge about osteoporosis among certain patient groups, increasing their risk of fractures. Patients with fragility fractures, male individuals, and those who are unemployed or have limited English proficiency tend to know less about osteoporosis.

A new ending to an old 'tail'

Researchers at the Salk Institute have uncovered a new structural beacon, called the C-tail, which is found in half of all telomeres in alternative lengthening of telomeres (ALT) tumors. This unique feature may be a key to understanding cancer cell immortality and developing effective treatments.

Early warning system for Alzheimer's disease

Researchers at the University of Strathclyde have developed a new technique that can detect Alzheimer's disease earlier than current methods. This approach uses fluorescence signals to identify clusters of peptide associated with the disease, allowing for potential treatment development and screening patients without needles or wires.

First articles in new neuroscience journal -- Brain Connectivity -- debut online

The new journal Brain Connectivity debuts with four compelling articles exploring brain connectivity, functional networks, and neurological disorders. Researchers discuss advances in neuroimaging methods, brain activity reconstruction, and white matter studies, shedding light on the organization and development of brain connections.

Wayne State University chosen as Michigan's sole participant in EcoCAR 2

Wayne State University students will explore advanced vehicle solutions to minimize petroleum usage and reduce emissions through research collaboration with industry. The university was chosen as Michigan's sole participant in EcoCAR 2, a three-year competition that aims to inspire and educate the next generation of automotive engineers.

Evolution can cause a rapid reduction in genome size

Researchers have decoded the entire genome of lyre-leaved rock cress, a close relative of the thale cress, revealing that its genome is significantly larger. The study found that considerable elements were lost from the thale cress genome, with hundreds of thousands of small deletions accounting for most of the differences in size.

Salmonella utilize multiple modes of infection

Researchers at Helmholtz Centre for Infection Research found a new Salmonella infection mechanism targeting the actin cytoskeleton and exploiting myosin II motor protein. This approach allows bacteria to pull themselves into host cells without forming ruffles, expanding the known invasion strategies.
