Anti-cancer drug gets a boost when combined with antirheumatic

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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

EurekAlert! - 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.
