Diamond-based circuits can take the heat for advanced applications

Apr 10 2018 - 00:04
When power generators transfer electricity, they lose almost 10 percent of the generated power. To address this, scientists are researching new diamond semiconductor circuits to make power conversion systems more efficient. Researchers in Japan successfully fabricated a key circuit in power conversion systems using hydrogenated diamond. These circuits can be used in diamond-based electronic devices that are smaller, lighter and more efficient than silicon-based devices. They report their findings in this week's Applied Physics Letters.

Research suggests alternative treatment for beta blocker intolerant heart attack patients

Apr 10 2018 - 00:04
Beta blockers have become a prescription drug staple for recovering heart attack patients. However, these blood pressure-reducing medications cannot be tolerated by many patients who are at higher risk for developing cardiovascular disease, including those with chronic obstructive pulmonary disease (COPD) and asthma, the elderly, and diabetics. As seen in the March 26 issue of Thyroid, researchers at New York Institute of Technology College of Osteopathic Medicine (NYITCOM) now pose a new treatment for patients with beta blocker intolerance: thyroid hormone therapy.

Impact of Medicare annual wellness visit on detection of cognitive impairment is minimal

Apr 10 2018 - 00:04
In the first nationwide study to measure the effect of the Medicare Annual Wellness Visit on early identification of cognitive impairment such as Alzheimer's disease, researchers from the Indiana University Center for Aging Research, Regenstrief Institute and IU Center for Health Innovation and Implementation Science found the visit has only minimal impact on detection of cognitive impairment as well as on subsequent cognitive testing and care.

Hepatitis C: A novel point-of-care assay

Apr 10 2018 - 00:04
One of the major challenges identified by the WHO in efforts to eradicate the hepatitis C virus is the diagnosis of chronic cases that are generally asymptomatic. Major progress is required for new diagnostic techniques that can be 'decentralized,' in other words accessed by populations and countries with limited resources. Scientists from the Institut Pasteur and Inserm, in collaboration with the company genedrive, have developed and validated a rapid, reliable, point-of-care HCV assay.

Researchers propose a blockchain data network to boost manufacturing

Apr 10 2018 - 00:04
Researchers are proposing the creation of a public, open-source network that uses blockchains -- the technology behind cryptocurrencies -- to share verifiable manufacturing data. The system could be used as a peer-to-peer network that allows companies to find small- and medium-sized manufacturers that are capable of producing specific components on a reliable basis.

New study shows invasive Chinese privet can be well controlled with lower concentrations of herbicide

Apr 10 2018 - 00:04
Chinese privet is one of the most invasive shrubs in the southeastern United States -- frequently growing in dense thickets along roadsides, on rights of way and in forests. Now the journal Invasive Plant Science and Management has good news for land managers battling the shrub. Researchers say you can achieve great control with much less herbicide than typically used.

Bugs, microbes and death can inform the living

Apr 10 2018 - 00:04
A Michigan State University study, published in the current issue of Nature Scientific Reports, shows that the postmortem microbiome -- populations of micro-organisms that move in after death -- can provide crucial insights into public health. What's telling is that regardless of many factors -- sex, ethnicity or even type of death -- the microbiome is consistent and distinct, depending on the number of days after death.
