Quantum particles at play: Game theory elucidates the collective behavior of bosons

3 hours 12 min ago
Quantum particles behave in strange ways and are often difficult to study experimentally. Using mathematical methods drawn from game theory, physicists have shown how bosons, which like to enter the same state, can form multiple groups.

Mathematics reveals how fluid flow affects bacteria

3 hours 13 min ago
Researchers have used mathematical equations to shed new light on how flowing fluid hinders the movement of bacteria in their search for food.

Patient portals could widen health disparities

4 hours 53 min ago
Online patient portals are increasingly important for doctor-patient communication and access to health care information. But patient portals could widen the gap in health disparities. Patients with low health literacy, less education and who are African American were much less likely to use these portals compared with white patients and those who were more health literate. These people lose the opportunity to easily engage their doctor about health concerns or medications, quickly refill prescriptions and get lab results, authors of a new report say.

Blogging on the ice: Connecting audiences with climate-change sciences

5 hours 52 min ago
Climate change is a perennially controversial subject frequently splashed across mainstream headlines. However, what we see in the news is not always what the scientists at the front line of climate change experience. Some scientists have been trying to counteract these misconceptions via citizen journalism and directly connecting with the public through blogging rather than official media channels.

Researchers train computers to identify gene interactions in human tissues

Mon, 04/27/2015 - 16:48
Researchers have trained a computer to crunch big biomedical data in order to recognize how genes work together in human tissues. Combining genomic data from 38,000 experiments, this research group has generated functional genetic maps for 144 human tissues types and organs. This big step in the use of large genomic data sets enables great strides in functional human genetics, with important applications for treatment of disease. The findings shed light on genetic interactions that underlie human diseases, the investigators say.

Is the universe a hologram?

Mon, 04/27/2015 - 14:16
The 'holographic principle,' the idea that a universe with gravity can be described by a quantum field theory in fewer dimensions, has been used for years as a mathematical tool in strange curved spaces. New results suggest that the holographic principle also holds in flat spaces. Our own universe could in fact be two dimensional and only appear three dimensional -- just like a hologram.

Mass and shape of single molecules revealed

Mon, 04/27/2015 - 14:16
Scientists have developed a revolutionary new technology that can image and weigh single molecules and instantly identify a single virus or bacteria particle.

Computer cooling system could save U. S. $6. 3 billion in electricity a year

Mon, 04/27/2015 - 14:13
A patented passive cooling system for computer processors could save U.S. consumers more than 6.3 billion dollars per year in energy costs.

3-D image of live embryo turning itself inside out

Mon, 04/27/2015 - 12:28
Researchers have captured the first 3-D video of a living algal embryo turning itself inside out, from a sphere to a mushroom shape and back again. The results could help unravel the mechanical processes at work during a similar process in animals, which has been called the 'most important time in your life.'

Outsmarting smartphones: Technology reduces distracted driving among teens

Mon, 04/27/2015 - 12:27
Technology can bolster efforts by parents, lawmakers and insurance companies to reduce distracted driving among novice teen drivers, according to a new study.

Parents sound off on mobile device use by children

Sun, 04/26/2015 - 15:05
Smartphones and tablets have become part of everyday life, but parents still worry that mobile devices may not be the best thing for their children, according to a new study.

How hospitals can improve outcomes of weekend surgeries

Sun, 04/26/2015 - 01:56
Studies have shown that patients who undergo surgeries on weekends tend to experience longer hospital stays and higher mortality rates and readmissions. For the first time, a new study has identified five resources that can help hospitals overcome this 'weekend effect': increased nurse-to-bed ratio; full adoption of electronic medical records; inpatient physical rehabilitation; a home-health program; and a pain management program.

Scientists develop first liquid nanolaser

Sat, 04/25/2015 - 01:31
Scientists have developed the first liquid nanoscale laser. And it's tunable in real time, meaning you can quickly and simply produce different colors, a unique and useful feature. The laser technology could lead to practical applications, such as a new form of a 'lab on a chip' for medical diagnostics. In addition to changing color in real time, the liquid nanolaser has additional advantages: it is simple to make, inexpensive to produce and operates at room temperature.

Team develops faster, higher quality 3-D camera

Sat, 04/25/2015 - 01:31
Inspired by the Microsoft Kinect and the human eye, scientists have developed an inexpensive 3-D camera that can be used in any environment to produce high-quality images.

Direct visualization of magnetoelectric domains

Fri, 04/24/2015 - 18:17
Using a novel microscopy technique, scientists revealed a major enhancement of coupling between electric and magnetic dipoles. The discovery could lead to devices for use in computer memory or magnetic sensors.

A new clinical trial is testing the feasibility and efficiency of a doctor in New York City remotely performing long-distance, tele-robotic ultrasound exams over the Internet on patients in Chicago.

Taking quantum sensing to a new level

Thu, 04/23/2015 - 18:27
Thermal imaging, microscopy and ultra-trace sensing could take a quantum leap with a new technique. Scientists used quantum correlated beams of light to overcome the fundamental detection limit of microcantilever-based sensors caused by intensity fluctuations.

Simplified model predicts patterns that form from honey-like fluids

Thu, 04/23/2015 - 17:04
Drizzling honey on toast can produce mesmerizing, meandering patterns, as the syrupy fluid ripples and coils in a sticky, golden thread. Dribbling paint on canvas can produce similarly serpentine loops and waves. The patterns created by such viscous fluids can be reproduced experimentally in a setup known as a "fluid mechanical sewing machine," in which an overhead nozzle deposits a thick fluid onto a moving conveyor belt. Researchers have carried out such experiments in an effort to identify the physical factors that influence the patterns that form.
