A new species of bamboo-feeding plant lice found in Costa Rica
06-Feb-12
Several periods of field work during 2008 have led to the discovery of a new species of bamboo-feeding plant lice in Costa Rica's high-altitude region "Cerro de la Muerte". The discovery was made thanks to molecular data analysis of mitochondrial DNA. The collected records have also increased the overall knowledge of plant lice (one of the most dangerous agricultural pests worldwide) from the region with more that 20%. The study was published in the open access journal ZooKeys.
Time = money = less happiness, study finds
06-Feb-12
What does "free time" mean to you? When you're not at work, do you pass the time -- or spend it?
New methodology assesses risk of scarce metals
06-Feb-12
Yale researchers have developed a methodology for governments and corporations to determine the availability of critical metals, according to a paper in Environmental Science & Technology.
Gender wage gap shrunk faster than previously thought
06-Feb-12
The gap in wages between men and women has decreased sharply over the past 30 years, and a new University of Georgia study reveals that decline was even greater than previously recognized.
The butterfly effect in nanotech medical diagnostics
06-Feb-12
Tiny metallic nanoparticles that shimmer in the light like the scales on a butterfly's wing are set to become the color-change components of a revolutionary new approach to point-of-care medical diagnostics, according to a study published in International Journal of Design Engineering.
ESO team succeeds in linking telescopes at Paranal Observatory into giant VLT
06-Feb-12
(PhysOrg.com) -- Researchers working as part of the European Southern Observatory (ESO) at the Cerra Paranal Mountain Observatory in the Atacama Desert in Chile, have succeeded in virtually connecting all four main Unit Telescopes (UTs) at the site, completing a project ten years in the making. Connecting the telescopes together virtually allows for the creation of a single virtual mirror that allows researchers to capture images from space as if all of the telescopes were in fact one giant telescope with a mirror 130m in diameter. Combined, the telescopes are known as the Very Large Telescope (VLT).
Women born to older mothers have a higher risk of developing breast cancer
06-Feb-12
A new study analyses the influence that certain birth and infancy characteristics have on mammographic density – an important indicator of breast cancer risk. The results reveal that women born to mothers aged over 39 years and women who were taller and thinner than the average girl prior to puberty have a higher breast density. This brings with it an increased risk of developing breast cancer.
Progress and promise in DIAL LIDAR
06-Feb-12
For climatologists and environmental policy makers who need to determine the flux of greenhouse gases (GHG), there are three paramount questions: Where is it, how much is there, and how is it moving? A new measurement approach is being developed and tested by a PML research team and NIST colleagues that may provide answers of unprecedented accuracy to all three.

In this video Dr Beverley Glover explains how a daisy is a collection of tiny flowers grouped together to make it look like a single big flower.
PML's Pernstich develops open-source software to automate test equipment
06-Feb-12
A free, easily customizable software program for automating test equipment via GPIB or RS232 bus may sound too good to be true, especially for smaller companies, graduate students, and hobbyists or for day-to-day laboratory work. But that's exactly what Kurt Pernstich of the PML's Semiconductor and Dimensional Metrology Division has created.
High planetary tilt lowers odds for life?
06-Feb-12
Highly-tilted worlds would have extreme seasons, subjecting life to alternating periods of scorching and subzero temperatures. This could make the development of all but hardiest, simplest creatures a long shot.
Jurassic salamanders with stomach contents found from Inner Mongolia
06-Feb-12
Paleontologists from Chinese Academy of Sciences reported two Jurassic salamanders with stomach contents from Daohugou, Ningcheng County, Inner Mongolia, China, as reported in Chinese Science Bulletin online January 2012 (Vol.57, No.1). This is the first report of well-established fossil caudates with food in their stomachs, and these specimens provide important evidence supporting hypotheses about ecological interactions in the Jurassic ecosystem of Daohugou.
3Qs: Figuring out Facebook's financials
06-Feb-12
Following much anticipation, Facebook filed for an initial public offering (IPO) after U.S. markets closed on Wednesday. Reports have speculated that the social media giant’s offering — pending approval from the Securities and Exchange Commission (SEC) — could top rival Google Inc.’s 2004 IPO, which holds the record for the largest U.S. Internet IPO, raising $1.9 billion at a valuation of $23 billion. Northeastern University news office asked David Sherman, professor of accounting in the College of Business Administration, to analyze Facebook’s IPO prospectus and explain what it reveals.
Playing RFID tag with sheets of paper
06-Feb-12
Radio Frequency Identification (RFID) tags are an essential component of modern shopping, logistics, warehouse, and stock control for toll roads, casino chips and much more. They provide a simple way to track the item to which the tag is attached. Now, researchers in France have developed a way to deposit a thin aluminum RFID tag on to paper that not only reduces the amount of metal needed for the tag, and so the cost, but could open up RFID tagging to many more systems, even allowing a single printed sheet or flyer to be tagged.
