More than 100 years ago, German Nobel laureate Paul Ehrlich popularized the "magic bullet" concept -- a method that clinicians might one day use to target invading microbes without harming other parts of the body. Although chemotherapies have been highly useful as targeted treatments for cancer, unwanted side effects still plague patients. Now, researchers at the University of Missouri have demonstrated that specialized nucleic acid-based nanostructures could be used to target cancer cells while bypassing normal cells.
You probably know Easter Island as "the place with the giant stone heads." This remote island 2,300 miles off the coast of Chile has long been seen as mysterious--a place where Polynesian seafarers set up camp, built giant statues, and then destroyed their own society through in-fighting and over-exploitation of natural resources.
Philadelphia, August 13, 2018 - The incidence of coronary artery compression in children fitted with epicardial pacemakers may be slightly more common than previously believed, say noted cardiologists. After reviewing patient records at Boston Children's Hospital, they advocate for stricter monitoring to identify patients at risk and prevent complications.
AUGUSTA, Ga. (Aug. 13, 2018) - Higher levels of oxidative stress in males results in lower levels of a cofactor needed to make the powerful blood vessel dilator nitric oxide, researchers report.
An antioxidant appears to help level the playing field between males and females of the cofactor BH? deep inside the kidneys - where the fine-tuning of our blood pressure happens - and restore similar production levels of protective nitric oxide.
Yokohama, Japan - Researchers have demonstrated holonomic quantum gates under zero-magnetic field at room temperature, which will enable the realization of fast and fault-tolerant universal quantum computers.
A quantum computer is a powerful machine with the potential to solve complex problems much faster than today's conventional computer can. Researchers are currently working on the next step in quantum computing: building a universal quantum computer.
LAWRENCE -- In ethnic enclaves, Mexican immigrants tend to spend less on food per week while East Asian immigrants spend more, which could explain the difference in assimilation rates and contrast in ethnic population density among the two groups, according to a University of Kansas study.
LAWRENCE -- A group of Americans and Europeans has relocated to a Costa Rican community in recent decades, and despite the government cheering the economic jolt, their isolation from locals there more highlights the privilege of these migrants who drastically transform coastal villages, according to a study by a University of Kansas researcher.
"Americans and Europeans are not thought of as migrants, more like expatriates or tourists," said Erin Adamson, a doctoral candidate in sociology. "But they have a really large economic impact on the places they go."
A major new study has shown that rotavirus vaccination reduced infant diarrhoea deaths by 34% in rural Malawi, a region with high levels of child deaths.
The study led by scientists at the University of Liverpool, UCL, Johns Hopkins Bloomberg School of Public Health and partners in Malawi provides the first population-level evidence from a low-income country that rotavirus vaccination saves lives.
Nature has provided us not only the fantastic materials, but also the inspiration for the design and fabrication of high-performance biomimetic engineering materials. Woods, which have been used for thousands of years, have received considerable attention due to the low density and high strength. The unique anisotropic cellular structure endow the woods with outstanding mechanical performances. In recent decades, various materials have been produced into monolithic materials with anisotropically cellular structures, trying to duplicate the lightweight and high-strength woods.
WASHINGTON - The U.S. Naval Research Laboratory's unique expertise in sun-viewing telescopes will be an integral part of the historic NASA Parker Solar Probe mission scheduled to launch Aug. 11 to better understand how the Sun affects our solar system.
The mission to "touch the Sun" is 60 years in the making and will bring a spacecraft carrying a suite of instruments the closest ever before to the Sun with NRL's Space Science Division's coronagraph telescopes called the Wide-Field Imager for Solar Probe, or WISPR, being the only imager.
