Physicist cracks women's random but always lucky choice of X chromosome

A University of Warwick physicist has uncovered how female cells are able to choose ...e. Now researchers led by University of Warwick physicist Dr Mario Nicodemi have explained how this randomness occurs and why that it is beneficial. This will...

Fused nasal bones helped tyrannosaurids dismember prey

...prey." Snively and co-authors, number-crunching physicist Donald Henderson from the Royal Tyrrell Museum of Palaeontology and Doug Phillips from the University of Calgary, compared the skulls and teeth of a number of tyrannosaurids to non-tyrannosaurids. In one of the first studies that looked at the struct...

Danish researches solve virus puzzle

This interdisciplinary work between physics and biology has been very fruitful and will be published April 3rd in the prestigious scientific journal PNAS, Proceedings of the National Academy of S...

Microfluidic chip helps solve cellular mating puzzle

...o and Paliwal, who teamed up with Alex Groisman, a physicist from the University of California, San Diego. In place of the microscopic electrical circuitry of a computer chip, their device consists of a series of tiny channels and chambers, some 20 times smaller than the diameter of human hair. Within the chip...

Penn researcher shows that DNA gets kinky easily at the nanoscale

...om the United States and the Netherlands, led by a physicist from the University of Pennsylvania, DNA is much more flexible than previously believed when examined over extremely small lengths. They used a technique called atomic force microscopy to determine the amount of energy necessary to bend DNA over nan...

Salmon farms kill wild fish, study shows

... salmon, " said study co-author Dr. Neil Frazer, a physicist at the University of Hawai'i. "We considered only the direct effects of sea lice on fish survival. We did not include the secondary effects of increased predation on infected fish." "The debate is over," said study co-author Alexandra Morton, a bio...

Nanoparticle assembly enters the fast lane

...rogrammable rules," said Oleg Gang, the Brookhaven physicist who leads the research team. "Using biological materials such as DNA, we are developing approaches to control the assembly of inorganic nano-objects. However, in order to really turn this attractive approach into nanotechnology, we have to understan...

NASA study: Alaskan fires affected Houston air quality in 2004

...n the air ?across North America. That same summer, physicist Gary Morris, both an associate professor at Valpariaso and an adjunct assistant professor at Rice, launched the Tropospheric Ozone Pollution Project (TOPP) at Rice's Houston campus with funding support from both NASA and Rice's Shell Center for Susta...

Researchers use multiphoton microscopy to watch chromosomes in action

...ce microscopy, a technique pioneered at Cornell by physicist Watt W. Webb, researchers have for the first time been able to watch chromosomes change their form in order to activate their genes to synthesize key proteins in fruit fly cells. The advance could be a significant step toward understanding the basic ...

Quick -- what’s that smell?

...it takes to identify complex odors." Rinberg, a physicist and computational neuroscientist, comments, "The development of color television was based on extensive studies of visual sensory processing. Modern MP3 players are built based on a deep knowledge about properties of our hearing capabilities. Similar...

Rice scientists unveil 'nanoegg'

...ctrical properties, said co-author and theoretical physicist Peter Nordlander, professor of physics and astronomy. The reasons for this have to do with the odd and often counterintuitive rules that govern how light interacts with electrons at the nanoscale. "All metal particles have a sea of free electrons f...

MIT 'seeing machine' offers hope to blind

...ences; the late Steve Benton, an acclaimed optical physicist and MIT professor; and former MIT affiliate James Cain. She has also worked with dozens of MIT graduate students and undergraduates, including Sylvia Gonzalez (S.B. 2003) and Shima Rayej (S.B. 2004), who helped design and construct the seeing machi...

Radiation-armed robot rapidly destroys human lung tumors

... patients just 3-4 months after treatment, medical physicist Cihat Ozhasoglu, Ph.D. of the University of Pittsburgh Medical Center will report in early August at the 48th Annual Meeting of the American Association of Physicists in Medicine in Orlando. Although it is too early to determine the technique's long...

"Obviously, a key objective is to bring these patients home and to ensure that their loved ones and the environment are properly protected." ...

Purdue creates new low-cost system to detect bacteria

...ing a mathematical method created in 1934 by Dutch physicist Fritz Zernike, who created a set of mathematical "descriptors" subsequently called radial Zernike polynomials. These descriptors can be used to analyze how light-wave patterns are distorted after passing through lenses having complex flaws or aberrat...
