NASA Satellites Paint Grim Picture For The Future of Antarctica’s Ice Shelves
For the entire 64 years NASA has been around, agency administrators have been forced to answer the dreaded what’s-the-point? question. What’s the point, legislators and taxpayers ask, of spending so much money in space when there are so many problems on Earth? NASA has always had a ready answer, pointing to the generations of Earth-observing satellites it has launched, which have...
Respected snake researcher dies from rattlesnake bite
A respected snake researcher who had been making significant discoveries about the species since childhood has died after being bitten by a timber rattler.
Do videos show ivory-billed woodpecker, or is it extinct?
The federal government has been asked to consider at least two videos made in recent years as evidence that ivory-billed woodpeckers may still exist.
Overcoming a major manufacturing constraint
Additive manufacturing (AM) using two-photon polymerization lithography (TPP) has increased in usage in industry and research. Currently, a major constraint of TPP in general and specifically of the material IP-Q (Nanoscribe GmbH, Germany) is the users' limited access to knowledge about material properties. Due to the nature of the process, the elastic properties in particular depend not only on...
Bug eyes and bat sonar: Bioengineers turn to animal kingdom for creation of bionic super 3D cameras
A pair of UCLA bioengineers and a former postdoctoral scholar have developed a new class of bionic 3D camera systems that can mimic flies' multiview vision and bats' natural sonar sensing, resulting in multidimensional imaging with extraordinary depth range that can also scan through blind spots.
Optical microscope strategy allows observers to check electrons moving inside gold
A team led by DGIST professor Seo Dae-ha has developed an experimental strategy to control and observe the chemical reaction of a single nanocatalyst using an optical microscope. The work is expected to contribute to catalyst design based on accurate understanding of the photocatalytic reaction through an analysis method that helps understanding the electron excitation phenomenon and transition...
How monsoon winds impact climate change by transporting pollutants into the upper atmosphere
While the Asian monsoon brings rain that is vital for the agricultural economy of the vast region, it is also known to suck up into the upper atmosphere chemical pollutants that accelerate climate change.
A review article clarifies genotype-independent plant transformation
Recently, researchers from North Carolina State University and the Beltsville Agricultural Research Center published the first review of research progress on genotype-independent plant transformation. In this review, researchers discussed recent advances in the use of regulatory genes in plant transformation and regeneration, as well as their potential to facilitate genotype-independent plant...
A simple way of sculpting matter into complex shapes
A new method for shaping matter into complex shapes, with the use of 'twisted' light, has been demonstrated in research at the University of Strathclyde.
