The US saw nearly 20,000 cases of Lyme disease in 2006 and there are up to 2,000 cases a year in the UK, a figure that is increasing steadily. Now scientists at the Centers for Disease Control and Prevention in Fort Collins, Colorado, USA, have developed an injection that protects against two severe diseases transmitted by tick bites: Lyme disease and Anaplasmosis.
“Along the North-eastern seaboard of the US, ticks are often co-infected with the bacteria that cause Lyme disease and Anaplasmosis,” says Dr Nordin Zeidner. “Currently there is no vaccine to protect against either organism. We have shown that a single injection of sustained-release antibiotics can prevent both diseases in mice.”
A single dose of doxycycline given orally is only 20-30% effective at preventing these diseases in mice. The researchers found that a new formulation of doxycycline hyclate that is programmed to release the drug over a 20 day period is 100% effective.
“The underlying copolymer formulation has been in use for over 20 years. It has no adverse effect on humans and it can be programmed to release a drug over several weeks to several months,” says Dr Zeidner. “We plan to test the doxycycline formulation to develop different release kinetics and delivery methods. For example, a slow release patch could be used in conjunction with current recommended protection against ticks, such as repellents and personal tick checks.”

Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
