Anthrax, rabbit fever and brucellosis

How can the population be better protected from highly pathogenic bacteria in food?

08-Aug-2016

Infectious diseases such as anthrax, tularaemia (rabbit fever) and brucellosis only occur rarely in Germany. However, these pathogens can do great harm if they are allowed, deliberately or by mistake, to enter the food chain. The reasons for such dissemination can be natural catastrophes such as ...

Better Contrast Agents Based on Nanoparticles

05-Aug-2016

Scientists at the University of Basel have developed nanoparticles which can serve as efficient contrast agents for magnetic resonance imaging. This new type of nanoparticles produce around ten times more contrast than the actual contrast agents and are responsive to specific environments. ...

Beating the heat a challenge at the nanoscale

03-Aug-2016

Rice University scientists who analyze the properties of materials as small as a single molecule have encountered a challenge that appears at very low temperatures. In trying to measure the plasmonic properties of gold nanowires, the Rice lab of condensed matter physicist Douglas Natelson ...

Novel 'repair system' discovered in algae may yield new tools for biotechnology

02-Aug-2016

A new way of fixing inactive proteins has been discovered in an algae, which uses chloroplast extracts and light to release an interrupting sequence from a protein. Research specialist Stephen Campbell and Professor David Stern at the Boyce Thompson Institute report the discovery. This repair ...

The Glowing Brain

Method conveys medical interrelationships quickly and intuitively

01-Aug-2016

On the monitor, a brain spins slowly and can be examined from every angle. Suddenly, some sections start glowing, first on the side and then the entire back of the head. These spectacular images show which brain areas activate when we speak, see, hear, or touch.. The method originated at the ...

New non-invasive imaging method for showing oxygen in tissue

29-Jul-2016

Learning how to look inside a body without having to cut it open is still an important part of medical research. One of the great challenges in imaging remains the visualization of oxygen in tissue. A team led by Prof. Vasilis Ntziachristos, Chair for Biological Imaging at the Technical ...

Severity of enzyme deficiency central to favism

27-Jul-2016

The congenital disease favism causes sickness and even jaundice in patients after they consume beans. The culprit is a particular enzyme deficiency, which destroys the red blood cells. Scientists from the University Children’s Hospital Zurich have now discovered that, in the event of a severe or ...

Ultrasensitive sensor using N-doped graphene

26-Jul-2016

A highly sensitive chemical sensor based on Raman spectroscopy and using nitrogen-doped graphene as a substrate was developed by an international team of researchers working at Penn State. In this case, doping refers to introducing nitrogen atoms into the carbon structure of graphene. This ...

Mapping electromagnetic waveforms

Novel electron microscope can visualize electromagnetic fields oscillating at frequencies of billions of cycles per second

26-Jul-2016

Temporally varying electromagnetic fields are the driving force behind the whole of electronics. Their polarities can change at mind-bogglingly fast rates, and it is difficult to capture them in action. However, a better understanding of the dynamics of field variation in electronic components, ...

Why is Usain Bolt the fastest person on Earth?

Researchers observe muscles at work with the help of new microscopes

25-Jul-2016

Twenty metres before the finish line Usain Bolt already opens his arms in triumph and ramps up his speed: even with his “handbrake” on, at 9.58 seconds, he runs the 100 metre stretch faster than anyone ever before in 2009 in Berlin. In the process, he reached a maximum speed of almost 45 ...
