Engineering a better device to capture -- and release -- circulating tumor cells

Apr 18 2018 - 00:04
Yaling Liu, of Lehigh University, has created an innovative microfluidic device that uses magnetic particles and wavy-herringbone design to capture and release circulating tumor cells with an 80-95% capture efficiency rate at different tumor cell concentrations. Liu will present some of his findings today, April 18th, at a conference taking place in Istanbul, Turkey called The Future of Medicine hosted by Royal Academy of Science International Trust (RASIT) and Bahçe?ehir University.

Direct electrical current used to preferentially inhibit pain-transmitting neurons

Apr 18 2018 - 00:04
Using computer models and laboratory rats, Johns Hopkins researchers have demonstrated that "direct electrical current" can be delivered to nerves preferentially, blocking pain signals while leaving other sensations undisturbed.

New study improves 'crowd wisdom' estimates

Apr 18 2018 - 00:04
In a new study published in the Journal of the Royal Society Interface, researchers Albert Kao (Harvard University), Andrew Berdahl (Santa Fe Institute), and their colleagues examined just how accurate our collective intelligence is and how individual bias and information sharing skew aggregate estimates. Using their findings, they developed a mathematical correction that takes into account bias and social information to generate an improved crowd estimate.

Some kitchen cabinets can emit potentially harmful compounds

Apr 18 2018 - 00:04
Probably the last place anyone would want to find airborne polychlorinated biphenyl compounds (PCBs) is in the kitchen, yet that's exactly where scientists detected their presence, according to a new report in ACS' journal Environmental Science & Technology. They say that the PCBs, which are widely considered carcinogenic, are unwanted byproducts of sealant breakdown in modern kitchen cabinetry.

The 'radical' ways sunlight builds bigger molecules in the atmosphere

Apr 18 2018 - 00:04
With summer approaching, 'sea and sun' might conjure up images of a beach trip. But for scientists, the interactions of the two have big implications for the climate and for the formation of tiny droplets, or aerosols, that lead to clouds. In ACS Central Science, researchers demonstrate that sunlight can cause certain molecules at the ocean's surface to activate others, resulting in larger molecules that could affect the atmosphere.

New research shows Transcendental Meditation empowers disadvantaged Ugandan mothers

Apr 18 2018 - 00:04
A new study with disadvantaged women in Uganda using measures of self-efficacy, perceived stress, and mental and physical quality of life, found significant differences between a group practicing Transcendental Meditation and controls after three months. Results indicate improved ability to cope with difficult situations, decreased perceived stress, and improved clarity of mind and physical vitality. In follow-up questionnaires after 8 and 36 months, the women reported improvements in health, employment, and social relationships.

Overcoming bias about music takes work

Apr 18 2018 - 00:04
Expectations and biases play a large role in our enjoyment of experiences such as art and wine. Now, researchers at the University of Arkansas, Arizona State University and the University of Connecticut have found that simply being told that a performer is a professional or a student changes the way the brain responds to music, and overcoming this bias takes a deliberate effort. The results will be published in Scientific Reports on April 18.

Low-income HIV patients suffer with healthcare access

Apr 18 2018 - 00:04
Quebecers are not created equal when it comes to accessing anti-retroviral treatment (ART) for HIV and AIDS, a long-term study undertaken by a team from the Research Institute of the McGill University Health Centre (RI-MUHC) in Montreal has revealed. Researchers observed that HIV-infected persons who count on social assistance and other income security programs in Quebec do not have early access to ART due to their presumed lower socio-economic status.

Root exudates affect soil stability, water repellency

Apr 18 2018 - 00:04
We might think of roots as necessary, but uninteresting, parts of the crop production process. New research, however, focuses on what's going on in the soil with the plant's roots and the chemicals they produce.

Mayo Clinic study finds no evidence that anesthesia in young children lowers intelligence

Apr 18 2018 - 00:04
A Mayo Clinic study finds no evidence that children given anesthesia before their third birthdays have lower IQs than those who did not have it. A more complex picture emerges among people who had anesthesia several times as small children: Although their intelligence is comparable, they score modestly lower on tests measuring fine motor skills, and their parents are more likely to report behavioral and learning problems. The findings are published in Anesthesiology.

Active young adults with Type 1 diabetes have muscle complications: Study

Apr 18 2018 - 00:04
A new study from McMaster and York universities has found that poor muscle health may be a complication of Type 1 diabetes, even among active twenty-somethings. The researchers found structural and functional changes in the power generation parts of the cell, or mitochondria, of those with diabetes. Not only were the mitochondria less capable of producing energy for the muscle, they were also releasing high amounts of toxic reactive oxygen species, related to cell damage.

Active young adults with Type 1 diabetes have muscle complications: Study

Apr 18 2018 - 00:04
The research team analyzed muscle biopsies of young adults with and without Type 1 diabetes who exceed Diabetes Canada's recommended weekly levels for physical activity. The researchers found structural and functional changes in the power generation parts of the cell, or mitochondria, of those with diabetes.

ALS treatment delays disease and extends life in rats

Apr 17 2018 - 00:04
Investigators at Cedars-Sinai are exploring a new way to treat amyotrophic lateral sclerosis (ALS) by transplanting specially engineered neural cells into the brain. Their new study shows the transplanted cells delayed disease progression and extended survival in animal models.

Battery's hidden layer revealed

Apr 17 2018 - 00:04
An international team led by Argonne National Laboratory makes breakthrough in understanding the chemistry of the microscopically thin layer that forms between the liquid electrolyte and solid electrode in lithium-ion batteries. The results are being used in improving the layer and better predicting battery lifetime.

Alpine grassland productivity not sensitive to climate warming on third pole

Apr 17 2018 - 00:04
HE Jinsheng's research team at the Northwest Institute of Plateau Biology, collaborating with scientists from Peking University, established a warming-by-precipitation manipulative experiment at the Haibei National Field Research Station of Alpine Grassland Ecosystem. By combining the field manipulative experiment, 32 years of field monitoring and a meta-analysis from nine sites across the plateau, the impact of climate change on species composition and net primary productivity in Tibetan alpine grasslands was investigated.

350,000 stars' DNA interrogated in search for sun's lost siblings

Apr 17 2018 - 00:04
An international team of astronomers has revealed the 'DNA' of more than 350,000 stars in the Milky Way, which should help them find the siblings of the sun, now scattered across the sky. This is the first major announcement of an ambitious survey as part of a quest to uncover the formulation and evolution of galaxies -- after the Australian-led Galactic Archaeology survey, called GALAH, commenced three years ago.
