Today, the Centers for Disease Control and Prevention (CDC) confirmed test results reported late last night by the Texas Department of State Health Services’ public health laboratory showing that a healthcare worker at Texas Presbyterian Hospital is positive for Ebola. Show More Summary
Two research teams working in the same laboratories have found distinct solutions to a critical challenge that has held back the realization of super powerful quantum computers. The teams created two types of quantum bits, or "qubits" -- the building blocks for quantum computers -- that each process quantum data with an accuracy above 99%.
In spite of its dangerous reputation, cholesterol is in fact an essential component of human cells. By mapping the structure of a key enzyme involved in making it, researchers have gained new insight into this complex process with implications for understanding and treating disease, including high cholesterol.
The efficacy of nine essential oil-based products and two detergents that are labeled and marketed for bed bug control were evaluated by researchers. When the researchers sprayed the 11 non-synthetic pesticides directly on bed bug nymphs,...Show More Summary
Medical devices implanted in the body or in contact with flowing blood present two critical, life-threatening challenges for doctors treating their patients: blood clotting and bacterial infection. A team of scientists and engineers has developed a new surface coating for medical devices using FDA-approved materials. Show More Summary
Engineering researchers have made fluorescent molecules emit photons 1,000 times faster than normal -- a record in the field and an important step toward superfast light emitting diodes and quantum cryptography.
A technique to jump-start the body's systems for creating blood vessels has been developed by scientists, opening the door for potential new treatments for diseases whose impacts include amputation and blindness.
An innovative laboratory culture system has succeeded, for the first time, in reproducing the full course of events underlying the development of Alzheimer's disease. Using this system, investigators provide the first clear evidenceShow More Summary
Using a first-of-its-kind, high-resolution numerical model to describe ocean circulation during the last ice age about 21,000 year ago, oceanographers have shown that icebergs and meltwater from the North American ice sheet would have regularly reached South Carolina and even southern Florida.

Spintronics is a new field of electronics, using electron spin rather than charge. Scientists have now shown that a conventional electrical insulator can be used as an optimal spintronic device.
A new study led by a Canadian marine zoologist reviews the world list of specialist driftwood talitrids, which so far comprises a total of 7 representatives, including two newly described species. These tiny animals all live in and feed on decomposing marine driftwood. Show More Summary
A noninvasive method of delivering a promising therapy for persistent Clostridium difficile infection appears to be as effective as treatment via colonoscopy or through a nasogastric tube.
The long term population dynamics of the Crown-of-Thorns starfish, Acanthaster planci, has been the focus of recent study. This is one of the most long term and extensive surveys of its kind, with data spanning over 24 years through cooperation with the Japanese fishing population of Onna Village in Okinawa.

Small cues that display a user's transaction history may help a website feel almost as interactive as chatting with an online customer service agent, paving the way for more cost-effective websites, according to researchers.
No single 'one-size-fits-all' model can explain how biodiversity hotspots come to be, finds a study of more than 700 species of reptiles and amphibians in Madagascar. By analyzing the distribution of Madagascar's lizards, snakes, frogs...Show More Summary
Observing the quantum behavior of light is a big part of Alan Migdall's research at the Joint Quantum Institute. Many of his experiments depend on observing light in the form of photons -- the particle complement of light waves -- and...Show More Summary
Guidelines on how many pitches young athletes should throw have been developed to stem the tide of injuries, but many coaches are not following the recommendations consistently, according to a study.
Telling youths who are juggling multiple electronic devices to 'focus on the task at hand' may not always be good advice, according to research. Contrary to popular belief that multitasking leads to poor performance, researchers found the opposite is true for adolescents who spend a lot of time switching between media devices and tasks.

While it may take time before it’s known what impact email exchanges might have on patients and their care, a new study offers some early insights into the effects on doctors, suggesting that reimbursement models and physician workflow may need to adjust to accommodate message management.
More than 90 percent of potential pediatric fractures are splinted improperly in emergency rooms and urgent care centers, which can lead to swelling and skin injuries, according to a study.
