Read morePenn researchers show that protein unfolding is key for understanding blood clot mechanics
Fibrin, the chief ingredient of blood clots, is a remarkably versatile polymer. On one hand, it forms a network of fibers -- a blood clot -- that stems the loss of blood at an injury site while remain...
Life Sciences | Read moreJoint research into an enzyme that causes genetic diseases
Pyruvate carboxylase is a metabolic enzyme that plays a fundamental role in the metabolism of fatty acids (the components of fats) and sugars. When its function is not adequately performed (for exampl...
Life Sciences | Read moreNew study reveals structure of the HIV protein shell
Previously, scientists had known that the genetic material within HIV is enclosed within a shell called the capsid, which is formed by a honeycomb arrangement of about 250 hexagonal protein building b...
Life Sciences | Read moreTerahertz waves are effective probes for IC heat barriers
Their technique, described in a recent paper,* could become an important quality-control tool to help monitor semiconductor manufacturing processes and evaluate new insulating materials.Chip m...

Computers that could switch on instantly without the time-consuming process of “booting” an operating system is just one of the possibilities, according to a new paper by a team of researchers spannin...
Materials Sciences | Read moreNew Imaging Technique Reveals The Atomic Structure Of Nanocrystals
Optical and electronic properties of small assemblages of atoms called quantum dots depend upon their electronic structure – not just what’s on the surface, but also what’s inside. While scientists ca...
Physics and Astronomy | Read moreResearchers shake up scientific theory on motor protein
Researchers from the University's Astbury Centre for Structural Molecular Biology and from the University of Tokyo have for the first time identified key elements of dynein's structure, and ...
Life Sciences | Read moreNew Catalyst Paves the Path for Ethanol-Powered Fuel Cells
The highly efficient catalyst performs two crucial, and previously unreachable steps needed to oxidize ethanol and produce clean energy in fuel cell reactions. Their results are published online in th...

This instrument, which will be devoted to studying matter at the atomic scale, is one of the best-performing in Europe. The microscope and its installation cost 2.38 M€, half of which was funded by CN...
Physics and Astronomy | Read moreResearchers Discover “On Switch” for Cell Death Signaling Mechanism
The research, performed by Stefan Riedl, Ph.D., and colleagues, published online on Dec. 31 in the journal Nature, highlights how protein-protein interactions between Fas receptor and Fas-associated d...
Life Sciences | Read moreBrilliant light source for X-ray microscopy permits three-dimensional imaging of biological cells
The task of analyzing the internal structure of biological cells is a relatively complex affair. When using an electron microscope, the whole cells first have to be fixed, followed by the time-consumi...
Physics and Astronomy | Read moreProtein 'tubules' free avian flu virus from immune recognition
Two domains or portions of the protein NS1 combine to form tiny tubules where double-stranded RNA is hidden from the immune system, said Dr. B. V. Venkataram Prasad, professor of biochemistry and mole...
Life Sciences | Read moreResearch About Plant Viruses Could Lead to New Ways to Improve Crop Yields
The cost of worldwide crop losses due to plant diseases is estimated at $60 billion annually. Although there are no good estimates of the cost of plant viruses alone, the viruses are generally conside...
Agricultural and Forestry Science | Read moreScientists peel away the mystery behind gold's catalytic prowess
Few materials have exercised as much of a hold on the human imagination, or on human history, as has gold.But for all of its popular uses – money, medals, jewelry and more – gold's potent...
