A team of researchers from the Department of Biochemistry and Molecular Biology and the Institute of Neuroscience at the Universitat Autònoma de Barcelona has discovered that tetanus toxin, which causes tetanus, could be extremely useful as a therapy against psychological disorders such as depression, anxiety and anorexia, and to slow the progress of neurodegenerative disorders such as Parkinson’s disease.
Tetanus toxin is a neurotoxin belonging to the same family as botulinum neurotoxins, which cause botulism. These have been successfully used as a therapy to treat disorders caused by abnormal muscular contractions such as strabismus, cerebral palsy, anal contractions and torticollis. Recently these toxins have been used even in cosmetics against wrinkles. For these therapeutic and cosmetic applications, the scientists are working with sublethal doses of toxins.
Led by José Aguilera, scientists from the Department of Biochemistry and Molecular Biology and the Institute of Neuroscience at the UAB, have studied whether it would also be possible to use sublethal doses of tetanus toxin and molecules derived from tetanus toxin for therapeutic purposes. The results have been obtained in the laboratory after 20 years of studying these toxins, and they are very encouraging.

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.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
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...
