The University of Rochester will mark another important step in the effort toward attaining sustainable fusion, the ultimate source of clean energy, Friday, May 16. University President Joel Seligman, along with special guests, will dedicate the new Omega EP (Extended Performance) laser facility at the Robert L. Sproull Center for Ultra High Intensity Laser Research at the Laboratory for Laser Energetics (LLE).

The Omega EP comprises a new set of four ultra-high-intensity laser beams that will unleash more than a petawatt—a million billion watts—of power onto a target just a millimeter across. Working in conjunction with LLE's original 60-beam Omega laser, the Omega EP will open the door to a new concept called "fast ignition," which may be able to dramatically increase the energy derived from fusion experiments and provide a possible new avenue toward clean fusion power. If successful, fast ignition could lead to the highest energy densities ever achieved in a laboratory.

Census of Marine Life-affiliated scientists, plumbing the secrets of a vast underwater mountain range south of New Zealand, captured the first images of a novel “Brittlestar City” established against daunting odds on the peak of a seamount – an underwater summit taller than the world’s tallest building.

Its cramped starfish-like inhabitants, tens of millions living arm tip to arm tip, owe their success to the seamount’s shape and to the swirling circumpolar current flowing over and around it at roughly four kilometers per hour. It allows Brittlestar City’s underwater denizens to capture passing food simply by raising their arms, and it sweeps away fish and other hovering would-be predators.

Discovery of this marine metropolis, announced today along with important new insights into seamount geology and physics, highlighted a month-long April expedition to survey the Macquarie Ridge aboard the Research Vessel Tangaroa of New Zealand’s National Institute of Water & Atmospheric Research, host of the Census of Marine Life seamount programme, CenSeam. The voyage was largely funded by the New Zealand Foundation for Research, Science and Technology.


With systems biology methods, CancerSys investigates molecular- and cell-biological processes in the formation of tumors in the liver

Systems Biology is a young field with the overall aim of creating a holistic picture of dynamic life processes with regard to all levels - from the genome via the proteome and the organisation of the cell organelles all the way to the complete cell or even an entire organism. In doing so, Systems Biology takes into consideration the dynamic interplay of the components involved. In order to achieve this high aspiration, Systems Biology combines quantitative methods used in molecular biology with knowledge gathered in mathematics, informatics and systems science.

Obesity experts today questioned Burger King's commitment to improve its standards on marketing to children on the day it launched its new 'Indiana Jones' campaign in the US with toys, internet games and scratch competition prizes.

They fear the new campaign running on children's cable channels such as Nickelodeon and Disney will in effect promote the overall brand range including another Indiana Jones special - the Indy Double Whopper being sold in the USA at $4.29. The standard Double Whopper contains almost 1000 kcalories and a heart-stopping 30 grams of saturated fat.

Burger King's latest sales drive to children includes games linked to the latest Indiana Jones film, the Kingdom of the Crystal Skull. Promotions include a 'Reveal the Secret' scratch and win game, and a 'Big Dig' online game, and an 'adventure heroes' toy series to collect. Burger King has pledged to restrict its advertising to children under 12, which uses third-party licensed characters, to Kids Meals meeting its nutrition criteria.

Rochester Medical Center scientists reported in the May issue of Molecular Therapy that a vaccine they created prevents the development of Alzheimer’s disease-like pathology in mice without causing inflammation or significant side effects.

Alzheimer’s is a progressive neurodegenerative disease associated with dementia and a decline in performance of normal activities. Hallmarks of the disease include the accumulation of amyloid plaques in the brains of patients and the loss of normal functioning tau, a protein that stabilizes the transport networks in neurons. Abnormal tau function eventually leads to another classic hallmark of Alzheimer’s, neurofibrillary tangle in nerve cells. After several decades of exposure to these insults, neurons ultimately succumb and die, leading to progressively damaged learning and memory centers in the brain.

Women ask for considerably lower salaries in salary negotiations than men but it may be because they are expected to do so, according to a dissertation in psychology by Una Gustafsson at Lund University in Sweden.

Conceptions of good and poor negotiators are tied to stereotypical notions of masculine and feminine characteristics: good negotiators are regarded as being decisive, strong, and self-assertive - masculine qualities. Poor negotiators are seen as being concessive, emotional, and overly focused on relationships, which are regarded as feminine qualities, she says.

But Una Gustafsson also warns against placing the entire blame on the women’s own behavior.
