UCLA researchers developed the technique and measuring device
UCLA biophysicists have developed a new method to rapidly determine a single cell’s stiffness and size — which could ultimately lead to improved treatments for cancer and other diseases. (more…)
Lightweight, compact device converts an ordinary smartphone into an advanced fluorescence microscope
Fluorescence microscopes use technology that enables them to accomplish tasks not easy to achieve with normal light microscopes, including imaging DNA molecules to detect and diagnose cancer, nervous system disorders such as Alzheimer’s disease, and drug resistance in infectious diseases. (more…)
As the climate warms and sea ice retreats, the North is changing. An ice-covered expanse now has a season of increasingly open water that is predicted to extend across the whole Arctic Ocean before the middle of this century. Storms thus have the potential to create Arctic swell – huge waves that could add a new and unpredictable element to the region. (more…)
A solar tsunami observed by NASA’s Solar Dynamics Observatory (SDO) and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun’s magnetic field.
Solar tsunamis are produced by enormous explosions in the Sun’s atmosphere called coronal mass ejections (CMEs). As the CME travels out into space, the tsunami travels across the Sun at speeds of up to 1000 kilometres per second.
Similar to tsunamis on Earth, the shape of solar tsunamis is changed by the environment through which they move. Just as sound travels faster in water than in air, solar tsunamis have a higher speed in regions of stronger magnetic field. This unique feature allowed the team, led by researchers from UCL’s Mullard Space Science Laboratory, to measure the Sun’s magnetic field. The results are outlined in a paper soon to be published in the journal Solar Physics. (more…)
Dozens of atmospheric scientists, including three University of Washington faculty members, are taking part in what’s being described as one of the largest atmospheric field campaigns in decades.
The six-week Southeast Atmosphere Study, through July 15, includes scientists from more than 30 different institutions. Together they are studying how pollutants combine with natural vegetation emissions to affect climate and air quality in the Southeastern U.S. (more…)
Even in the same animal, not all bites are the same. A new study finds that because the force in a muscle depends on how much it is stretched, an animal’s bite force depends on the size of what it is biting. The finding has direct implications for ecology and evolution.
PROVIDENCE, R.I. [Brown University] — Many animals prefer food — snails, nuts, etc. — that must be cracked and crushed. Scientists have measured the maximum force of their impressive bites before, but a new study introduces a significant subtlety: bite force depends not only on the size and strength of the eater, but also the size of the eatee. That insight has important implications in the lives of predators and prey. (more…)
New Report “Digital Wallet Road Map 2013” Offers Data, Insights and Strategies for Overcoming Barriers on Awareness, Understanding of Benefits, Availability and Security Concerns
RESTON, VA, February 4, 2012 – comScore, Inc., a leader in measuring the digital world, today released the Digital Wallet Road 
Map 2013, a study which measures consumer awareness, perceptions and intent to use current digital wallet offerings. The study found that digital wallets, which store a virtual copy of the contents of a consumer’s physical wallet to facilitate online or offline retail transactions, only had awareness among 51 percent of U.S. consumers for wallets other than PayPal.
“Digital wallets represent an innovative technology that has not yet reached critical mass among consumers due to a variety of factors, including low awareness and a muddied understanding of their benefits,” said Andrea Jacobs, comScore Payments Practice Leader. “This study delves deeply into the mindset of consumers with respect to their potential use of digital wallets, in addition to helping size the market opportunity. The study also provides guidance on how digital wallet providers, marketers, developers and retailers can contribute to growing adoption of this technology.” (more…)
PASADENA, Calif. – In a clever reuse of hardware originally built to test parts of NASA’s QuikScat satellite, the agency will launch the ISS-RapidScat instrument to the International Space Station in 2014 to measure ocean surface wind speed and direction.
The ISS-RapidScat instrument will help improve weather forecasts, including hurricane monitoring, and understanding of how ocean-atmosphere interactions influence Earth’s climate. (more…)
