Anti-cancer drug gets a boost when combined with antirheumatic

Mié, 03/29/2017 - 22:00
Scientists at EPFL and NTU have discovered that combining an anticancer drug with an antirheumatic produces improved effects against tumors. The discovery opens a new path for drug-drug synergy.

Blind tadpoles learn visually with eyes grafted onto tail, neurotransmitter drug treatment

Mié, 03/29/2017 - 22:00
Blind tadpoles were able to process visual information from eyes grafted onto their tails after being treated with a small molecule neurotransmitter drug that augmented innervation, integration, and function of the transplanted organs. The work, which used a pharmacological reagent already approved for use in humans, provides a potential road map for promoting innervation -- the supply of nerves to a body part -- in regenerative medicine.

Napping flies have higher resistance to deadly human pathogen

Mié, 03/29/2017 - 22:00
A new University of Maryland study finds that fruit flies that take frequent naps have the strongest resistance to both a fungal infection and to Drosophila 'superbug' bacteria. The unexpected finding of dual resistance to the two different pathogens suggests genes regulating factors involved in general immune system resistance to disease played a bigger role than did the genes conferring disease-specific resistance.

When it comes to biological populations, expect the unexpected

Mié, 03/29/2017 - 22:00
More than three decades of data on the physical, chemical and biological variables in 11 Midwestern lakes show that while lake temperatures and nutrient concentrations rise within relatively expected ranges, biological organisms achieve high population extremes.

Cannabis use may predict opioid use in women undergoing addictions treatment, study says

Mar, 03/28/2017 - 22:00
Researchers have found that women in methadone treatment who use cannabis are 82 per cent more likely to continue using opioids. This means that women who use cannabis are at high risk of failing methadone treatment. Tailoring treatment to the patient's sex can help to deliver more accurate, personalized treatment.

New research into light particles challenges understanding of quantum theory

Mar, 03/28/2017 - 22:00
Scientists have discovered a new mechanism involved in the creation of paired light particles, which could have significant impact on the study of quantum physics.Researchers at the University of East Anglia (UEA) have shown that when photons -- the fundamental particles of light -- are created in pairs, they can emerge from different, rather than the same, location.

Very low frequency electromagnetic field exposure linked to motor neurone disease

Mar, 03/28/2017 - 22:00
Workplace exposure to very low frequency electromagnetic fields may be linked to a doubling in risk of developing the most common form of motor neurone disease -- amyotrophic lateral sclerosis, or ALS for short -- suggests research published online in Occupational & Environmental Medicine.

Every £1 spent on public health in UK saves average of £14

Mar, 03/28/2017 - 22:00
Every £1 spent on public health returns an extra £14 on the original investment, on average -- and in some cases, significantly more than that -- concludes a systematic review of the available evidence, published online in the Journal of Epidemiology & Community Health.

A faster single-pixel camera

Mar, 03/28/2017 - 22:00
Reporting their results in the journal IEEE Transactions on Computational Imaging, researchers from the MIT Media Lab now describe a new technique that makes image acquisition using compressed sensing 50 times as efficient. In the case of the single-pixel camera, it could get the number of exposures down from thousands to dozens.

Researchers track perfluorinated chemicals in the body

Mar, 03/28/2017 - 22:00
New research in the journal Environmental Science & Technology Letters shows scientists have developed a method to track perfluorinated alkyl substances (PFAS) in the body. PFAS are potentially toxic chemicals found in stain-resistant products, nonstick cookware, fire-fighting foams and -- most recently -- fast food wrappers.

IUPUI researcher lays groundwork for new ways to prevent youth violence in Caribbean

Mar, 03/28/2017 - 22:00
A study by an Indiana University School of Social Work associate professor at Indiana University-Purdue University Indianapolis has laid the groundwork for new strategies dealing with youth violence in five Caribbean countries

Nurse volunteer activities improve the health of their communities, workforce study says

Mar, 03/28/2017 - 22:00
A new study describes nurses' perceptions of how they promote health in their communities through a whole lot of both formal and informal volunteer work.

Making bones stronger

Mar, 03/28/2017 - 22:00
New treatments for osteoporosis are desperately needed. Two University of Delaware scientists report estimates of potentially the most effective dosage of a particular peptide, with results that could raise density levels in badly degraded bones back to healthy levels.

Brain scans show dopamine levels fall during migraine attacks

Mar, 03/28/2017 - 22:00
Using PET scans of the brain, University of Michigan researchers showed that dopamine falls and fluctuates at different times during a migraine headache.

Team highlights work on tuning block polymers for nanostructured systems

Mar, 03/28/2017 - 22:00
High-performance materials are enabling major advances in a wide range of applications from energy generation and digital information storage to disease screening and medical devices. Block polymers, which are two or more polymer chains with different properties linked together, show great promise for many of these applications, and a research group at the University of Delaware has made significant strides in their development over the past several years.

Case comprehensive cancer center analyzes brain tumor data, doubles known risk factors for glioma

Mar, 03/28/2017 - 22:00
A massive new study involving blood samples from over 30,000 individuals has identified 13 new genetic risk factors for glioma, the most common type of malignant brain tumor in adults.

Reusable carbon nanotubes could be the water filter of the future, says RIT study

Mar, 03/28/2017 - 22:00
Enhanced single-walled carbon nanotubes offer a more effective and sustainable approach to water treatment and remediation than the standard industry materials -- silicon gels and activated carbon -- according to a paper by RIT researchers John-David Rocha and Reginald Rogers.

Fred Hutch scientists to cover advances in immunotherapy, proteomics at AACR

Mar, 03/28/2017 - 22:00
Scientists from the Fred Hutchinson Cancer Research Center in Seattle are scheduled to present and discuss the latest developments in immunotherapy and proteomics at the American Association for Cancer Research Annual Meeting, Research Propelling Cancer Prevention and Cures, on April 1-5.
