Quantum dots spotlight DNA-repair proteins in motion, says Pitt expert
Repair proteins appear to efficiently scan the genome for errors by jumping like fleas between DNA molecules, sliding along the strands, and perhaps pausing at suspicious spots, say researchers at the University of Pittsburgh, the University of Essex and the University of Vermont who tagged the proteins with quantum dots to watch the action unfold. The findings are available today in Molecular Cell.

Water oxidation advance boosts potential for solar fuel
Emory University chemists have developed the most potent homogeneous catalyst known for water oxidation, considered a crucial component for generating clean hydrogen fuel using only water and sunlight. The breakthrough, published March 11 in Science, was made in collaboration with the Paris Institute of Molecular Chemistry.The fastest, carbon-free molecular water oxidation catalyst to date "has really upped the standard from the other known homogeneous WOCs," said Emory chemist Craig Hill, whose lab led the effort.

First whole genome sequencing of family of 4 reveals new genetic power
(Institute for Systems Biology) The Institute for Systems Biology (ISB) has analyzed the first whole genome sequences of a human family of four. The findings of a project funded through a partnership between ISB and the University of Luxembourg was published online today by Science on its Science Express website. It demonstrates the benefit of sequencing entire families, including lowering error rates, identifying rare genetic variants and identifying disease-linked genes.

An end to lice: The effectiveness of a new oral treatment has been demonstrated
(INSERM (Institut national de la santé et de la recherche médicale)) French medical researchers from the AP-HP (Henri Mondor Hospital and Avicenne Hospital) and Inserm (Unit 738 "Models and methods for therapeutic evaluation of chronic illnesses" and CIC 202, at Tours) have recently demonstrated the effectiveness of a new molecule in the fight against lice. Faced with the emergence of increasing resistance to conventional treatments by these parasites, this new medication represents a real therapeutic alternative which is effective in 95 percent of cases.

Samsung Plans E-Reader, Barnes and Noble Partnership
Samsung will partner with Barnes Noble for its upcoming E60 eReader, which will access Barnes Noble's e-book store for downloadable texts and leverage the booksellers e-book lending feature. Originally announced at CES, the 6-inch Samsung device will rely on either a PC connection or built-in WiFi for book downloading, and include a stylus for inputting notes or using the scheduling and memo features. The device will also include a substantial audio component, with speakers for text-to-speech and the ability to leave audio memos. Despite being categorized as a niche industry early in 2009, e-readers have proliferated in recent months, leading to increased competition.
- Samsungs E60 eReader will make its debut in partnership with Barnes amp; Noble at some point in the spring, adding yet another competitor to the already crowded e-reader space. The device features a 6-inch screen, sliding form-factor, embedded front speakers for text-to-speech and a stylus for ...

Apple iPad Sales May Approach 7 Million in 2010, Says Report
General expectations of the Apple iPad's level of success are overly pessimistic, says a Broadpoint AmTech report, which predicts 2010 sales of up to 4 million units, or actual unit shipments of up to 7 million. An analyst suggests that getting a little quality time with the iPad will convert naysayers.
- Think the Apple iPad is nice enough, but no show-stopper? Don't be too quick to judge, Broadpoint AmTech analyst Brian Marshall wrote in a March 9 research note to investors, predicting that the next major catalyst for a rise in Apple shares will be the iPad launch. quot;We believe th...

Google Gesture Search Rekindles Android Fragmentation Debate
Google's Gesture Search feature for Android smartphones reignited the complaint about fragmentation and inconsistency among Google's mobile operating system platform because it only works on devices running Android 2.0 or greater, such as the Motorola Droid and Google Nexus One. Laptop Magazine's Mark Spoonauer said this means Google is favoring newer versions of its OS, punishing owners of devices running older flavors of Android, as well as Google's partners. Kevin Tofel tried to diffuse the situation by arguing that Google isn't the only mobile platform maker that faces this quandary.
- News Analysis: When Google released its Google Gesture Search feature for Android smartphones March 3, it fanned the flames of a long-standing complaint about fragmentation and inconsistency among Google's mobile operating system platform. Google Gesture Search, which lets users su...
