Peering into a grocery store bin, it's hard to tell if a peach or tomato or avocado is starting to go bad underneath its skin.
But an affordable camera technology being developed by the University of Washington and Microsoft Research might enable consumers of the future to tell which piece of fruit is perfectly ripe or what's rotting in the fridge.
Scientists have developed a new test to identify patients who are at risk of suffering a relapse from testicular cancer.
Assessing just three features of a common kind of testicular cancer - called non-seminomatous germ cell tumor - can identify those at most at risk of relapse even where there is no evidence of tumor spread.
The researchers believe the test could be used in the clinic to make decisions about which patients should be given chemotherapy.
Use of a qualification test within a retinal practice appeared to be effective in predicting which patients with intermediate age-related macular degeneration (AMD) would be good candidates to initiate use of a home monitoring device for progression to more severe AMD, according to a study published online by JAMA Ophthalmology.
An international team of scientists have identified potential 'tipping points' where abrupt regional climate shifts could occur due to global warming.
In the new study, published in Proceedings of the National Academy of Sciences of the United States of America (PNAS), the scientists analysed the climate model simulations on which the recent 5th Intergovernmental Panel on Climate Change (IPCC) reports are based.
Computers have scanned aerial photographs and conducted the first automated mass-crowd count in the world, thanks to the work of researchers at the University of Central Florida.
Counting large-scale crowds (such as the Million Man March in Washington, D.C.) has been a long, tedious process involving people examining aerial photographs one at a time. Until now, each photograph had to be divided into sections and the examiners counted the number of heads per inch.
Magnetic nanostructures - or rather: the interaction between charge, spin and current flow as a function of a temperature gradient in such structures - this is what the fast growing research area named "spin caloritronics" deals with. And this area of research has already come up with a number of newly discovered interesting effects and promising applications. Scientists from the Physikalisch-Technische Bundesanstalt (PTB) have, for the first time, succeeded in measuring the thermoelectric properties of a single magnetic domain wall.
Amsterdam, October 15, 2015 - Paper sensors that can be analyzed using an Android program on a smartphone could be used to detect pesticides rapidly and cheaply, according to a new study published in Biosensors and Bioelectronics.
As the role of pesticides in the decline of pollinator populations and their potential effect on health becomes clearer, it is increasingly important to be able to detect them in the environment and on foods. Usually the equipment used to detect pesticides and other chemicals is large, expensive and slow, making on-the-spot detection challenging.
Miss Georgia tripped in the final round of the 2015 Miss America Pageant. Jennifer Lawrence stumbled on her way to accept an Oscar. Even rock stars, world leaders and presidential candidates have fallen in front of the crowd or completely off stage.
And robots can too.
Protected and intact forests have been lost at a rapid rate during the first 12 years of this century. According to researchers at Aalto University, Finland, 3% of the protected forest, 2.5% of the intact forest, and 1.5% of the protected intact forest in the world were lost during 2000 - 2012. These rates of forest loss are high compared to the total global forest loss of 5% for the same time period.
A computer can do as good a job of predicting how many patients will be discharged from a hospital unit on a given day as doctors and nurses can, according to new research from the University of Maryland's Robert H. Smith School of Business and Johns Hopkins University. In some cases, the computer does even better.
The Global Precipitation Measurement (GPM) mission core satellite found moderate to heavy rainfall occurring in Tropical Depression Champi before it strengthened into a tropical storm.
Tropical Depression Twenty Five (TD25W) formed on Tuesday, October 13 east of Guam. The GPM core observatory satellite saw TD25W on October 13, 2015 at 1313 UTC (9:13 a.m. EDT) and found moderate to heavy rainfall falling at a rate of up to 67 mm (2.6 inches) per hour.
Researchers at ETH Zurich are using America's fastest supercomputer to make huge gains in understanding the smallest electronic devices.
The team, led by Mathieu Luisier, focuses on further developing the front line of electronics research - simulating and better understanding nanoscale components such as transistors or battery electrodes whose active regions can be on the order of one-billionth of a meter, or about as long as your fingernails grow in one second.
A team of researchers from Brown University, ETH Zurich, and the Swiss National Supercomputing Centre is using America's most powerful supercomputer to help understand and fight diseases affecting some of the body's smallest building blocks.
Totally internal confined whispering-gallery modes can have high Q factors in wavelength scale optical microresonators, such as microspheres and two-dimensional microdisk resonators. Square optical resonators can also support high Q whispering-gallery modes, suitable to realize unidirectional microlasers.
Drivers are more likely to get behind the wheel drowsy than drunk despite it being just as dangerous, and the worst offenders are those under 30, a QUT study has found.
The research undertaken by QUT's Centre for Accident Research & Road Safety - Queensland (CARRS-Q) will be presented today at the 2015 Australasian Road Safety Conference on the Gold Coast, which runs until October 16.
