Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…
On that date the comet passed by Mars at approximately 87,000 miles (about one-third the distance between Earth and the Moon). At that time, the comet and Mars…
The brightest synchrotron light source in the world has delivered its first x-ray beams. The National Synchrotron Light Source II (NSLS-II) at the U.S….
Plasmonic devices combine the ‘super speed’ of optics with the ‘super small’ of microelectronics. These devices exhibit quantum effects and show promise as…
Rosetta’s comet 67P/Churyumov-Gerasimenko is beginning to show a clearly visible increase in activity. While in the past months most of the dust emitted from…
Re-examining longstanding beliefs about the physics of these devices, Princeton engineers have now shown that carefully restricting the delivery of power to…
“It took 50 years to show that this phenomenon indeed happens,” said Vesna Mitrovic, associate professor of physics at Brown University, who led the work. “We…
Chinese Hamster ovary (CHO) cells are commonly used as a mammalian expression system for the production of recombinant proteins. They are one of the few cell types that can be grown at high cell density as the cells are resistant to metabolic stress. However, given the considerable production costs it is of major importance to maximize the recombinant protein yield. The present invention allows for significantly increasing the recombinant protein expression level in CHO cells using a standard promoter. This is achieved by silencing the Galectin-1 gene through RNAi. The lentiviral Galectin-1-knockdown (>90%) increases the expression level of the protein of interest more than 1,5-fold. No further amendments are required.
Standard quantum theory places no limit on particle size and current experiments use larger and larger particles, which exhibit wave-like behaviour. However,…
The invention concerns a process for the production of bifurcated vascular prostheses by the polymer-processing technology electrospinning.
The roadmap focuses on strategic and tactical objectives to support the federal government's accelerated adoption of cloud computing. This final document…
The pair of patches was spotted by a NASA-led international team of researchers investigating the chemical make-up of Titan’s atmosphere.
On an otherwise quiet Sunday on September 28, the Suomi NPP mission team was monitoring a possible close approach of a debris object. By early evening, the…
NASA’s Solar Dynamics Observatory captured images of the event, which occurred in the lower half of the sun. This flare is classified as an X1.6 class flare….
The European Space Agency's Rosetta mission will deploy its lander, Philae, to the surface of Comet 67P/Churyumov-Gerasimenko on Wednesday 12th November after…
Massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, a study has found.
The present innovation provides stable aqueous suspensions of water-insoluble, but biodegradable diblock copolyesters which can be further processed in multiple ways, for instance via electrospinning.
