A team of researchers from the Universitat Autònoma de Barcelona, lead by Professor Jordi Alberola, has demonstrated the efficacy and safety of a new type of antibiotic, belonging to the family called antimicrobial peptides, for treating canine leishmaniasis, which is a disease that also affects humans. It is the first time that these antibiotics have been demonstrated to be useful against parasitic diseases in real clinical situations. The antibiotic can also improve treatment of other infections, parasitic or not, in that no side effects have been observed and it is very difficult for organisms to develop resistance to them. In addition, it can also have a direct application as a drug for treating co-infection of leishmaniasis with HIV, which 10 % of people with AIDS suffer from. The findings will be published this month (February) in the magazine Antimicrobial Agents and Chemotherapy, which is the most prestigious in its field.
Twelve million people around the world are affected by leishmaniasis; 400 million more are at risk of suffering the disease and every year between 60,000 and 100,000 people die from it. Furthermore, nearly 2 million new cases are reported every year. The different forms of leishmaniasis are caused by unicellular parasites of the Leishmania genus, which are mainly spread by biting insects, similar to mosquitoes, called phlebotoms. Clinical manifestations range from slight cutaneous lesions to visceral complications that may lead to the individual’s death.
Dogs are the main reservoir of the parasite in Spain and in the rest of the Mediterranean basin, the Middle East and South America. Epidemiological studies show that around 70% of dogs in the Mediterranean area are infected. Consequently, eradication of the disease in dogs is considered to be one of the main objectives for improving human health.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
