Quantum computer built inside a diamond

A team of scientists has built a quantum computer in a diamond, the first of its kind to include protection against "decoherence" -- noise that prevents the computer from functioning properly.

Quantum control protocols could lead to more accurate, larger scale quantum computations

A protocol for controlling quantum information pioneered by researchers at UC Santa Barbara, the Kavli Institute of Nanoscience in Delft, the Netherlands, and the Ames Laboratory at Iowa State University could open the door to larger-scale, more accurate quantum computations. Their findings, in a paper titled "Decoherence-protected quantum gates for a hybrid solid-state spin register," are...

Reducing hospital admissions for asthmatics

Children with moderate or severe asthma attacks who are treated with systemic corticosteroids during the first 75 minutes of triage in the emergency department were 16 percent less likely to be admitted to the hospital.

Reproductive seasonality observed in male giant pandas

A three-year study of giant pandas reveals that reproductive seasonality exists not only in female pandas, but in male pandas as well. According to the authors, this new understanding of the regulators of male reproductive function will allow continued improvement of the captive panda management program and will, one day, assist in reintroducing pandas into the wild.

Researchers develop a new cell and animal model of inflammatory breast cancer

Inflammatory breast cancer is a very aggressive, often misunderstood type of cancer. The five-year survival rate is between 25 and 50 percent. The reason for the poor prognosis is that IBC usually grows rapidly and often spreads quickly to other parts of the body. Researchers at Fox Chase have developed a new cell and animal model that holds promise for providing a detailed understanding the...

Researchers present new findings for glioblastoma at American Association for Cancer Research

Physician-scientists from University Hospitals Case Medical Center's Seidman Cancer Center and Case Western Reserve University School of Medicine presented new research findings in 24 presentations this week at Annual Meeting of the American Association for Cancer Research.Two innovative studies are investigating novel methods that may help clinicians bring a greater specificity to the treatment...

Researchers uncover a viable way for colorectal cancer patients to overcome drug resistance

When combined with other treatments, the drug cetuximab has been shown to extend survival in certain types of cancer. Unfortunately, about 40 percent of colorectal cancer patients -- specifically those who carry a mutated form of a gene called KRAS -- do not respond to the drug. Researchers at Fox Chase, however, have been working on a way to overcome this resistance by unleashing a second...

Rising CO2 levels linked to global warming during last deglaciation

Many scientists have long suspected that rising levels of carbon dioxide and the global warming that ended the last Ice Age were somehow linked, but establishing a clear cause-and-effect relationship between CO2 and global warming from the geologic record has remained difficult. A new study identifies this relationship and provides compelling evidence that rising CO2 caused much of the global...

Scientists uncover multiple faces of deadly breast cancer

An international team of scientists, including four at Simon Fraser University, has made a discovery that will change the way the most deadly form of breast cancer is treated. The journal Nature has just published the team's findings online in the paper The clonal and mutational evolution spectrum of primary triple negative breast cancers. The study is the largest genetic analysis of what were...

Sexually abused boys at risk for more unsafe sex: UBC research

Young males who have been sexually abused are five times more likely to cause teen pregnancy compared to those with no abuse history, according to University of British Columbia research. Sexually abused boys are also three times more likely to have multiple sexual partners and twice as likely to engage in unprotected sex.

Single baby boomers facing increased challenges as they age

Nick and Bobbi Ercoline, the couple depicted on the "Woodstock" soundtrack album cover, have now been happily married for over 40 years. However, a new special issue of The Gerontologist showing the Ercolines as they look today -- a portrait of successful aging -- finds that their unmarried baby boomer counterparts generally fare much poorer in terms of economic, health, and social outcomes.

Some 'improved cookstoves' may emit more pollution than traditional mud cookstoves

The first real-world, head-to-head comparison of "improved cookstoves" (ICs) and traditional mud stoves has found that some ICs may at times emit more of the worrisome "black carbon," or soot, particles that are linked to serious health and environmental concerns than traditional mud stoves or open-cook fires. The report, which raises concerns about the leading hope as a clean cooking technology...

Spontaneous gene glitches linked to autism risk with older dads

Researchers have turned up a new clue to the workings of a possible environmental factor in autism spectrum disorders (ASDs): fathers were four times more likely than mothers to transmit tiny, spontaneous mutations to their children with the disorders. Moreover, the number of such transmitted genetic glitches increased with paternal age. The discovery may help to explain earlier evidence linking...

Sports take brain as well as brawn

Elite soccer players have superior executive functions relative to non-players, and there is a significant correlation between their cognitive function and number of goals and assists.

Stickleback genome holds clues to adaptive evolution

Scientists searching for genetic clues to vertebrate evolution have long been fascinated by the tiny marine stickleback fish, known for its ability to adapt and thrive in salty oceans or freshwater streams around the world. Now, a team of researchers from the Broad Institute and Stanford University has analyzed the entire genetic sequence of 21 threespine sticklebacks and identified which regions...

Studies: Memory declines faster in years closest to death; mental activity best protection

New research finds that a person's memory declines at a faster rate in the two- and-a-half years before death than at any other time after memory problems first begin. A second study shows that keeping mentally fit through board games or reading may be the best way to preserve memory during late life. Both studies are published in the April 4, 2012, online issue of Neurology, the medical journal...
