AUSTIN, Texas — Seed size is controlled by small RNA molecules inherited from a plant’s mother, a discovery from scientists at The University of Texas at Austin that has implications for agriculture and understanding plant evolution.
“Crop seeds provide nearly 70 to 80 percent of calories and 60 to 70 percent of all proteins consumed by the human population,” said Z. Jeff Chen, the D.J. Sibley Centennial Professor in Plant Molecular Genetics at The University of Texas at Austin. “Seed production is obviously very important for agriculture and plant evolution.” (more…)
*Increase in ocean acidification led to collapse of oyster seed production at Oregon hatchery*
Marine researchers have definitively linked the collapse of oyster seed production at a commercial oyster hatchery in Oregon to an increase in ocean acidification.
Larval growth at the hatchery declined to a level considered by the owners to be “non-economically viable.”
A study by the scientists found that increased seawater carbon dioxide (CO2) levels, resulting in more corrosive ocean water, inhibited the larval oysters from developing their shells and growing at a pace that would make commercial production cost-effective. (more…)
In a study that pushed quantum mechanical theory and research capabilities to the limit, UA researchers have found a way to see the molecule that likely made the universe – or at least the hot and fiery bits of it.
Lurking in the vast, chilly regions between stars, the unassuming molecule known as a triatomic hydrogen ion, or H3+, may hold secrets of the formation of the first stars after the Big Bang.(more…)
U launches groundbreaking new Ojibwe-English ‘talking’ dictionary.
Eugene Stillday was born in Ponemah on the Red Lake Indian Reservation, where he grew up speaking Ojibwe. That is, until his public school teachers forbade him from the practice and punished him and his classmates for speaking the only language they knew.
“[So] we developed a system,” Stillday says. “We’d be talking to each other in Ojibwe, and when the teacher came nearby we’d just naturally swing into English, and when she left, you know, right back to Ojibwe.” (more…)
Cybersecurity expert Hathaway discusses risks of modern digital world
The near future of digital technology could allow citizens to turn on their toaster ovens via the Internet from just about anywhere, but these developments could pose serious threats to individuals’ safety, according to a cybersecurity expert.
Melissa Hathaway, a former senior director for cyberspace in the National Security Council, highlighted examples of the threats the Internet has created for both national and personal security during a University of Delaware Global Agenda speaker series presentation on Wednesday night, April 11, in Mitchell Hall.

Bat wings are like hands: meaty, bony and full of joints. A new Brown University study finds that bats take advantage of their flexibility by folding in their wings on the upstroke to save inertial energy. The research suggests that engineers looking at flapping flight should account for wing mass and consider a folding design.
PROVIDENCE, R.I. [Brown University] — Whether people are building a flying machine or nature is evolving one, there is pressure to optimize efficiency. A new analysis by biologists, physicists, and engineers at Brown University reveals the subtle but important degree to which that pressure has literally shaped the flapping wings of bats.
The team’s observations and calculations show that by flexing their wings inward to their bodies on the upstroke, bats use only 65 percent of the inertial energy they would expend if they kept their wings fully outstretched. Unlike insects, bats have heavy, muscular wings with hand-like bendable joints. The study suggests that they use their flexibility to compensate for that mass. (more…)
*AICTE adopts cloud to improve technical education and prepare students for the workforce of tomorrow.*
NEW DELHI and REDMOND, Wash. — Microsoft Corp. and All India Council for Technical Education (AICTE) announced today that AICTE is deploying Microsoft Live@edu over the next three months to more than 10,000 technical colleges and institutes throughout India. The cloud deployment will expand students’ access to high-quality technical education and collaboration.
Live@edu is a hosted communication and collaboration service that offers email, Microsoft Office Web Apps, instant messaging and storage to AICTE’s more than 7 million students and nearly 500,000 faculty members, for a total reach of 7.5 million users — roughly double the size of the Los Angeles population — making AICTE Microsoft’s largest cloud customer ever. Live@edu is the first step in AICTE’s deployment of Microsoft cloud computing for education. AICTE also plans to deploy Microsoft Office 365 for education when it becomes available later this year, providing access to Microsoft Exchange Online email and calendar, Microsoft SharePoint Online, Microsoft Lync Online and Microsoft Office Professional as the technical infrastructure to support member colleges and institutes.
