Researchers have developed a powdered form of an anthrax vaccine that could potentially be inhaled through the nose and eliminate the need for needle injections. The new vaccine, which appears promising in preliminary animal studies, may offer a faster and easier way to protect the general population as well as soldiers on the battlefield in the event of a deadly bioterror attack, the researchers say.
The development, a joint project of BD Technologies and the U.S. Army Medical Research Institute of Infectious Disease, was described today at the 228th national meeting of the American Chemical Society, the worlds largest scientific society.
The vaccine represents a growing pipeline of needle-free drug delivery technologies that are being developed for consumers, such as the FluMistTMintranasal vaccine currently sold to combat influenza. Considered the next generation anthrax vaccine, the new formulation is based on an anthrax recombinant protective antigen (rPA) and can be formulated as a dry powder and self-administered through the nose using a novel, disposable powder delivery device, the researchers say.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
