New silicon structure opens the gate to quantum computers

Dom, 12/10/2017 - 23:00
In a major step toward making a quantum computer using everyday materials, a team led by researchers at Princeton University has constructed a key piece of silicon hardware capable of controlling quantum behavior between two electrons with extremely high precision.

Single-dose vaccine could provide faster protection in cholera epidemics

Dom, 12/10/2017 - 23:00
Each year there are more than three million cases of cholera worldwide. Research at the University of Maryland School of Medicine now shows that giving a stronger single-dose of a live oral vaccine could be an effective tool in controlling outbreaks more quickly.

Survivorship care plan improves cancer care-related distress levels for HCT recipients

Dom, 12/10/2017 - 23:00
Survivorship care plan improves patient cancer care-related distress levels for hematopoietic cell transplant recipients. Results from a recent multicenter study presented at the American Society of Hematology (ASH) Annual Meeting.

CAR T-cell therapies drive outcomes in lymphoma, myeloma

Dom, 12/10/2017 - 23:00
For people with certain types of aggressive, refractory blood cancers, treatment options are woefully limited. But three studies being presented today at the 59th American Society of Hematology (ASH) Annual Meeting and Exposition in Atlanta spotlight the emerging role played by chimeric antigen receptor (CAR) T-cell therapies in helping individuals mount a clinical response and, in some cases, achieve durable remission.

Drug suppresses spread of breast cancer caused by stem-like cells

Dom, 12/10/2017 - 23:00
Rare stem-like tumor cells play a critical role in the spread of breast cancer, but a vulnerability in the pathway that powers them offers a strategy to target these cells using existing drugs before metastatic disease occurs, report University of California San Diego School of Medicine and Moores Cancer Center researchers.

Quality control is vital for the energy production of cells

Dom, 12/10/2017 - 23:00
Researchers have uncovered a mitochondrial error-correction mechanism, which is vital for the construction of the mitochondrial respiratory chain and the energy production of cells.

Your mood depends on the food you eat, and what you should eat changes as you get older

Dom, 12/10/2017 - 23:00
Diet and dietary practices differentially affect mental health in young adults versus older adults, according to new research from Binghamton University, State University of New York.

Researchers invent novel RNA nanotech to decorate exosomes for effective cancer therapy

Dom, 12/10/2017 - 23:00
A new study shows that attaching antibody-like RNA nanoparticles to microvesicles can deliver effective RNA therapeutics specifically to cancer cells. Researchers used RNA nanotechnology to apply the RNA nanoparticles and control their orientation. The microscopic, therapy-loaded extracellular vesicles successfully targeted three types of cancer in animal models. The findings could lead to a new generation of anticancer drugs that use siRNA, microRNA and other RNA-interference technologies.

How do you track a secretive hawk? Follow the isotopes

Dom, 12/10/2017 - 23:00
A study by the University of Cincinnati found that the rare Henst's goshawk of Madagascar hunts lemurs in low-lying areas that are most at risk to deforestation. Researchers could use this isotope analysis to study the habitat and prey needs of other threatened species that are difficult to track.

Researchers examine how errors affect credibility of online reviews

Dom, 12/10/2017 - 23:00
Shoppers increasingly consult online reviews before making holiday purchases. But how do they decide which reviewers to trust?Recently published research from the Indiana University Kelley School of Business at IUPUI shows that consumer trust in online reviews is influenced by spelling errors and typos. But how much those errors influence each consumer depends on the type of error and that consumer's general tendency to trust others.

Violence a matter of scale, not quantity, researchers show

Dom, 12/10/2017 - 23:00
Researchers at the University of Notre Dame studying violence found the larger the population of a society, the smaller its war group size, proportionally -- which means fewer casualties in a conflict.

Natural route masters

Dom, 12/10/2017 - 23:00
Few people draw a parallel between bumblebees and travelling salesmen but that's what comes after months of tracking the flight paths of the foraging pollinators as they refine their routes around multiple destinations and, in the process, provide insights into analogous problems in logistics and robotics and into how land might be used more efficiently.

Researchers find simpler way to deposit magnetic iron oxide onto gold nanorods

Dom, 12/10/2017 - 23:00
Researchers have found a simpler way to deposit magnetic iron oxide (magnetite) nanoparticles onto silica-coated gold nanorods, creating multifunctional nanoparticles with useful magnetic and optical properties.

High-intensity exercise delays Parkinson's progression

Dom, 12/10/2017 - 23:00
High-intensity exercise three times a week is safe for individuals with early-stage Parkinson's disease and decreases worsening of motor symptoms, according to a new phase 2, multi-site trial led by University of Colorado Anschutz Medical Campus and Northwestern Medicine scientists.

Certain books can increase infant learning during shared reading, study shows

Dom, 12/10/2017 - 23:00
Parents and pediatricians know that reading to infants is a good thing, but new research shows reading books that clearly name and label people and objects is even better.

Electromagnetic water cloak eliminates drag and wake

Dom, 12/10/2017 - 23:00
Engineers at Duke University develop a realistic proposition for creating a water cloak that moves water around an object by applying forces on dissolved ions through a carefully designed electromagnetic field.

Saturn's rings cast shadows, affect the planet's ionosphere

Dom, 12/10/2017 - 23:00
Data collected by the Cassini spacecraft, before it was deliberately crashed into Saturn's atmosphere in September 2017, show that the planet's illustrious rings are casting a shadow in ionized particles over the planet.

Insights on how SHARPIN promotes cancer progression

Dom, 12/10/2017 - 23:00
SBP and Technion Institute researchers have SHARPIN-ed their knowledge of how a malicious form of a protein drives the formation of melanoma through modulation of the PRMT5 pathway. The new research was published in the Journal of Clinical Investigation.

Dark side of the moon: Motorcycle deaths linked to full moons

Dom, 12/10/2017 - 23:00
On nights illuminated by a full moon, fatal motorcycle accidents increased by 5 percent compared to nights without a full moon. On evenings when the supermoon decorated the sky, this increased to 32 percent.

Study identifies barriers to transplant therapy to treat multiple myeloma among racial minority groups

Dom, 12/10/2017 - 23:00
A study by researchers at Mayo Clinic's campus in Jacksonville, Fla., has found that barriers to patients receiving stem cell therapy as part of their treatment for multiple myeloma include income, education, insurance status and access to care at an academic center or facility that treats a high volume of patients.
