Resident European shrimps may be beating back invaders from America, which means Europe has fared better on this battlefront than it has against the Californian grey squirrel and American crayfish. 

The researchers mapped the occurrence of the interloper and found it only existed where native shrimps were absent or rare. When native shrimps were common, the American shrimp simply could not establish and it disappeared. 

Chemists recently achieved a breakthrough in efforts to develop an economical means of harnessing artificial photosynthesis by narrowing the voltage gap between the two crucial processes of oxidation and reduction, according to a new paper.

The team reports it has come within two-tenths of the photovoltage required to mimic oxidation and reduction respectively using unique photoanodes and photocathodes the team developed using novel nanowire components and coatings. Narrowing the gap using economical chemical components, the group moves researchers closer to using the man-made reaction for unique applications such as solar energy harvesting and storage.

Normally muscles contract in order to support the body, but in a rare condition known as cataplexy the body's muscles "fall asleep" and become involuntarily paralyzed. Cataplexy is incapacitating because it leaves the affected individual awake, but either fully or partially paralyzed. It is one of the bizarre symptoms of the sleep disorder called narcolepsy.

Observational studies have reported that statins improve outcomes of various infections. Ventilator-associated pneumonia (VAP) is the most common infection in the intensive care unit (ICU) and is diagnosed in approximately 8 to 28 percent of ICU patients receiving mechanical ventilation.

Ventilator-associated pneumonia is associated with increased mortality rates and high health care costs. New treatments are needed to improve the outcomes of VAP, according to background information in the article. 

Phones are terrific today. They can play games and watch videos and check email - they are just terrible at making calls.

And during a natural disaster, when too many people take to their mobile phones at once, cellular networks easily overload.   Mai Hassan, a PhD student in the Department of Electrical and Computer Engineering at the University of British Columbia, has developed a solution to ensure that calls don't get dropped and texts make it to their destination.

Hassan found a way to opportunistically use television and radio channels to transmit cellular signals when systems are pushed beyond capacity.

Thermonuclear fusion can be achieved through a controlled reaction between two light variants of hydrogen, called deuterium and tritium - that sounds simple enough but improving the ignition stage of fusion reaction isn't trivial.

Theoretical calculations described in a paper published in EPJ D involve increasing the uniformity of irradiation using high-power laser beams on the external shell of a spherical capsule containing a mix of deuterium and tritium.
