Pancreatic cancer loses viral defenses when talking with supporting cells

Science Daily - Mon, 20/04/2015 - 4:29pm
Researchers have unlocked a way to make pancreatic cancer cells more vulnerable to cancer-killing viruses, known as oncolytic viruses. The scientists have discovered how they can exploit the communication, or cross-talk, between pancreatic cancer and a specific cell type that supports the tumor. They found that this cross-talk weakens the ability of both cell types to fight off cancer-fighting viruses.

Two tested approaches to treating childhood obesity appear effective

Science Daily - Mon, 20/04/2015 - 4:29pm
A study of two protocols for the treatment of childhood obesity finds that both were successful in limiting one-year weight gain in obese children. Both interventions use information technology to provide clinicians with up-to-date obesity management guidelines and tools to help families manage behaviors related to obesity and fitness.

Fake malaria drugs not as common as previously reported

Science Daily - Mon, 20/04/2015 - 4:28pm
A rigorous analysis of antimalarial drug quality conducted in Cambodia and Tanzania found no evidence of fake medicines, according to new research. Previous reports had suggested that up to one third of antimalarials could be fake. Researchers analysed 2,028 antimalarials from Tanzania and Cambodia. Samples were selected in a rigorous and representative way making this one of the most recent comprehensive data sets on antimalarial quality.

Genetic code of Upland cotton cracked

Science Daily - Mon, 20/04/2015 - 4:28pm
In a groundbreaking achievement, scientists have decoded the intricately woven genetic makeup of Upland cotton for the first time in the ancient plant's history. Upland cotton, which accounts for more than 90 percent of cultivated cotton worldwide and has a global economic impact of $500 billion, is the main source of renewable textile fibers.

Happily ever after: Scientists arrange protein-nanoparticle marriage

Science Daily - Mon, 20/04/2015 - 4:28pm
Researchers have discovered a way to easily and effectively fasten proteins to nanoparticles -- essentially an arranged marriage -- by simply mixing them together. The biotechnology is in its infancy. But it already has shown promise for developing an HIV vaccine and as a way to target cancer cells.

Reducing global tobacco use

Science Daily - Mon, 20/04/2015 - 4:28pm
Although global efforts to cut tobacco use have had some success, more can be done to reduce the number of deaths from smoking, according to a new commentary. More than 170 countries have signed the World Health Organization's (WHO) Framework Convention on Tobacco Control agreement since it was adopted in 2005. However, smoking rates are still high in many low- and middle-income countries compared with Canada and other high-income countries where efforts to curb smoking have been more successful.

Vampire squid discovery shows how little we know of the deep sea

Science Daily - Mon, 20/04/2015 - 4:28pm
Among soft-bodied cephalopods, vampire squid live life at a slower pace. At ocean depths from 500 to 3,000 meters, they don't swim so much as float, and they get by with little oxygen while consuming a low-calorie diet of zooplankton and detritus. Now, researchers have found that vampire squid differ from all other living coleoid cephalopods in their reproductive strategy as well.

Construction of the LSST telescope begins in Chile

Science Daily - Mon, 20/04/2015 - 4:26pm
The first stone of the future LSST telescope was laid on 14 April 2015 by the Chilean President Michelle Bachelet, at the Cerro Pachón site in the Chilean Andes. The LSST will be equipped with the most powerful digital camera ever built. The 8.4-meter-diameter telescope will shed light on the nature of dark energy, which accelerates the expansion of the Universe.< The LSST will achieve first light in 2019 and will be fully operational in 2022. The 8.4-meter-diameter telescope will image the sky systematically for ten years, providing a three-dimensional film of the entire visible Universe.

Video games in care homes: connecting older adults, or exposing age-related vulnerability?

Science Daily - Mon, 20/04/2015 - 4:26pm
Introducing video games as a means of bringing older adults in long-term care together may not always be an easy task, according to new research. Offering stimulating and accessible leisure activities such as this can be difficult for care providers as the impact of age-related changes and impairments on residents grows, authors of a new study warn.

Giant magnetic effects induced in hybrid materials

Science Daily - Mon, 20/04/2015 - 4:25pm
For a magnetic thin film deposited onto a transition metal oxide film, the magnetic properties change dramatically as the oxide undergoes a structural phase transition. The hybrid between a simple magnetic material and a transition-metal oxide provides a "window" to understand the metal-to-insulator transition and offers dramatic tunability of magnetic properties. Potential applications are envisioned in the fields of information storage and power transmission.

Ways to avoid catching diseases from pets

Science Daily - Mon, 20/04/2015 - 4:25pm
Pets can pass diseases to humans, especially when a pet owner's immune system is compromised. Here, veterinarians outline ways for families to avoid disease transmission by choosing the right type of pet--or making small changes in the ways they enjoy the pets they already have.

Pancreatic cancer breakthrough: Scientists turn cancer cells into normal cells

Science Daily - Mon, 20/04/2015 - 4:25pm
Scientists have found a novel avenue for therapeutic intervention of the "silent cancer." A new research study has shown that pancreatic cancer cells can be coaxed to revert back toward normal cells by introducing a protein called E47. E47 binds to specific DNA sequences and controls genes involved in growth and differentiation. The research provides hope for a new treatment approach for the more than 40,000 people who die from the disease each year in the United States.

Higher-than-expected pediatric cancer rates identified in two Florida areas

Science Daily - Mon, 20/04/2015 - 4:03pm
Higher-than-expected rates of pediatric cancers have been identified in the Miami metro area and an area west of the Everglades in a series of five statistical analyses. Comparisons across analyses reveal characteristics of the detected patterns, including the number of cases (two), types of cancer (leukemia or brain/central nervous system cancer) and the racial composition and timing of the cluster west of the Everglades.
