Is the finger-stick blood test necessary for type 2 diabetes treatment?

Posted: 10 Jun 2017 07:21 PM PDT

Blood glucose testing does not offer a significant advantage in blood sugar control or quality of life for type 2 diabetes patients who are not treated with insulin, suggests new research.

Graphene electrodes offer new functionalities in molecular electronic nanodevices

Posted: 09 Jun 2017 04:31 PM PDT

An international team of researchers has revealed a new way to tune the functionality of next-generation molecular electronic devices using graphene. The results could be exploited to develop smaller, higher-performance devices for use in a range of applications including molecular sensing, flexible electronics, and energy conversion and storage, as well as robust measurement setups for resistance standards. 

New form of carbon that's hard as a rock, yet elastic, like rubber

Posted: 09 Jun 2017 04:31 PM PDT

Carbon is an element of seemingly infinite possibilities. This is because the configuration of its electrons allows for numerous self-bonding combinations that give rise to a range of materials with varying properties. A team of scientists has developed a form of ultrastrong, lightweight carbon that is also elastic and electrically conductive. A material with such a unique combination of properties could serve a wide variety of applications from aerospace engineering to military armor.

Male farmers at highest risk of contracting 'monkey malaria' in Malaysia

Posted: 09 Jun 2017 04:31 PM PDT

Adult male farmers in Malaysia are more than twice as likely to contract Plasmodium knowlesi malaria -- an infection usually found only in monkeys -- than other people in their communities, according to a new study.

New cancer drug tested in mice may benefit certain leukemia patients

Posted: 09 Jun 2017 04:30 PM PDT

Up to 30 percent of adult acute lymphoblastic leukemia or ALL patients have Philadelphia chromosome, where two segments of chromosomes have aberrantly fused together. Adult ALL patients often see high relapse rates, and treatment-related deaths remain high. Researchers now report on a study that could provide better therapeutic options for patients.

Chemicals used to combat Zika, agricultural pests impact motor skills in infants

Posted: 09 Jun 2017 10:59 AM PDT

A chemical currently being used to ward off mosquitoes carrying the Zika virus and a commonly used insecticide that was threatened with a ban in the United States have been associated with reduced motor function in Chinese infants, a study found.

The brain's rejuvenating cells

Posted: 09 Jun 2017 10:59 AM PDT

A unique immune cell type has been discovered, which may lead to a future treatment for Alzheimer's disease, say investigators.

Analysis of complex protein interactions

Posted: 09 Jun 2017 10:57 AM PDT

A new, novel approach to monitor functional protein complexes has now been created by scientists.

Soft shelled turtles, food in China, likely spread cholera

Posted: 09 Jun 2017 10:38 AM PDT

The pathogen, Vibrio cholerae can colonize the surfaces, as well as the intestines of soft shelled turtles. This finding is strong evidence that soft shelled turtles in China, where they are grown for human consumption, are spreading cholera.

Fractal planting patterns yeild optimal harvests, without central control

Posted: 09 Jun 2017 10:38 AM PDT

Bali's famous rice terraces, when seen from above, look like colorful mosaics because some farmers plant synchronously, while others plant at different times. The resulting fractal patterns are rare for human-made systems and lead to optimal harvests without global planning.

Flaws in a tumor's genetic mending kit drive treatment response to immunotherapy

Posted: 09 Jun 2017 09:03 AM PDT

In an expanded, three-year clinical trial of 86 patients with colorectal and 11 other kinds of cancer that have so-called 'mismatch repair' genetic defects, scientists have found that half of the patients respond to an immunotherapy drug called pembrolizumab (Keytruda).

Robotic device developed to help stroke survivors recover

Posted: 09 Jun 2017 09:03 AM PDT

A new robotic tool has been developed for assessments of muscle overactivity and movement dysfunction in stroke survivors.

7 in 10 smartphone apps share your data with third-party services

Posted: 09 Jun 2017 07:38 AM PDT

Our mobile phones can reveal a lot about ourselves: where we live and work; who our family, friends and acquaintances are; how (and even what) we communicate with them; and our personal habits. With all the information stored on them, it isn't surprising that mobile device users take steps to protect their privacy. However, more than 70 percent of smartphone apps are reporting personal data to third-party tracking companies like Google Analytics, the Facebook Graph API or Crashlytics.

What will the future internet look like?

Posted: 09 Jun 2017 07:38 AM PDT

To tackle the all-important question "What will the future internet look like?" in the Digital Age, researchers have exchanged ideas to further progress.

Row, Row, Row Your Bots: But are they synchronized?

Posted: 09 Jun 2017 07:38 AM PDT

To get maximum propulsion, should a boat's team of rowers set their strokes to the same rhythm? Or should the rowers stagger the dropping and pulling of the oars through the water? Athletes and scientists have looked at the question, offering illuminating but inconclusive observations.

Demo plant produces renewable fuel from carbon dioxide captured from the air

Posted: 09 Jun 2017 07:38 AM PDT

The unique Soletair demo plant developed in Finland uses carbon dioxide to produce renewable fuels and chemicals. The aim of the project is to demonstrate the technical performance of the overall process and produce 200 liters of fuels and other hydrocarbons for research purposes. This concerns a one-of-a-kind demo plant in which the entire process chain, from solar power generation to hydrocarbon production, is in the same place.

Study improves remote detection of hazardous radioactive substances

Posted: 09 Jun 2017 07:22 AM PDT

A new method has been proposed that might be used to detect nuclear hazards from up to a few hundred meters away.

The first nanometrically-sized superelastic alloy

Posted: 09 Jun 2017 07:22 AM PDT

Researchers have explored superelasticity properties on a nanometric scale based on shearing an alloy's pillars down to nanometric size. The researchers have found that below one micron in diameter the material behaves differently and requires much higher stress for it to be deformed. This superelastic behavior is opening up new channels in the application of microsystems involving flexible electronics and microsystems that can be implanted into the human body.

Study examines link between obesity, food container chemical subsitutes

Posted: 09 Jun 2017 06:12 AM PDT

A pair of common chemicals that manufacturers use to make plastic food containers, water bottles, and other consumer products do not contribute to obesity to the extent of the chemical it's replacing.
