A laser system built on principles of supersymmetry

A team of researchers from the University of Central Florida and Michigan Technological University has developed a laser system concept built on the principles of supersymmetry. In their paper published in the journal Science, the group reports that their system is meant to solve the problem of producing more light with a compact laser system….

Research team develops a high-performance quantum dot mode-locked laser on silicon

Ten years into the future. That’s about how far UC Santa Barbara electrical and computer engineering professor John Bowers and his research team are reaching with the recent development of their mode-locked quantum dot lasers on silicon. It’s technology that not only can massively increase the data transmission capacity of data centers, telecommunications companies and…

Challenges and opportunities for brain health

Ever wondered how the World Federation of Neurology is working to foster quality neurology and brain health worldwide? William M Carroll and Wolfgang Grisold, of the World Federation of Neurology, discuss what can be done to increase research into neurological disorders and promote better and lasting brain health. Brain-related disorders such as epilepsy, Alzheimer’s disease,…

NIH study provides answer to long-held debate on blood sugar control after stroke

Findings may have immediate impact on clinical practice WHAT Hyperglycemia, or increased glucose, is common in patients with acute ischemic stroke and is associated with worse outcomes compared to normal glucose levels. Doctors all over the world have debated whether intensive glucose management, which requires the use of IV insulin to bring blood sugar levels…

How sperm stem cells maintain their number

The steady production of sperm relies on the number of sperm stem cells in the testis remaining constant. Researchers including Asst. Prof. Yu Kitadate and Prof. Shosei Yoshida (developmental biologists at the National Institute for Basic Biology within the National Institutes of Natural Sciences in Japan) and Prof. Benjamin Simons (a theoretical physicist at the…

Mesenchymal stems cells: Vital role in repair of damaged organs

In adults, mesenchymal stems cells (MSCs) are primarily found in bone marrow and they play a vital role in repair of damaged organs. The transformation of a single MSC into complex tissue like cartilage and bone starts with its association with other MSCs in order to form microscopic clusters via a process termed as condensation….

Fiber laser system emits exceptionally pure light

Recently researchers from Massachusetts have developed a novel fiber laser system that has a compact size and is able to emit light with a high level of spectral purity. Moreover, the fiber laser’s light remains unchanged to environmental conditions. The researchers confirm that the novel laser system will be useful for future scientific applications that…

CNS releases new clinical practice guidelines for thoracolumbar spine trauma

The Congress of Neurological Surgeons (CNS) has issued new clinical practice guidelines on the evaluation and treatment of patients with thoracolumbar spine trauma. The Congress of Neurological Surgeons Systematic Review and Evidence-Based Guidelines on the Evaluation and Treatment of Patients with Thoracolumbar Spine Trauma have been published today in full text on the CNS website…

Medicare reconsiders paying for seniors’ spine operations at surgery centers

Medicare is reviewing whether seniors should undergo spine surgeries at same-day surgery centers, the government-run health program announced Wednesday, five months after a USA Today Network-Kaiser Health News investigation revealed a spate of patient deaths following the procedures. The proposal states that Medicare officials will examine whether these procedures “pose a significant safety risk” to…
