Madrid, Spain: The antibiotic combination treatment piperacillin-tazobactam was significantly less effective than meropenem when treating potentially fatal bloodstream infections (BSI) caused by ceftriaxone-resistant Escherichia coli and Klebsiella pneumoniae and should be avoided when treating these organisms, according to research presented at the 28th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID) [1].

A new microchip technology capable of optically transferring data could solve a severe bottleneck in current devices by speeding data transfer and reducing energy consumption by orders of magnitude, according to an article published in the April 19, 2018 issue of Nature.

Barcelona, Spain: A rare but potentially serious complication following radiation treatment for cervical cancer is a narrowing of the tube (the ureter) that takes urine from the kidneys to the bladder, which can lead to kidney damage and sometimes life-threatening infections. This is called ureteral stricture and, until now, there have been concerns that brachytherapy might increase the risk, although the treatment itself is associated with better survival.

PROVIDENCE, R.I. [Brown University] -- Brown University researchers have developed a new theory to explain why stretching or compressing metal catalysts can make them perform better. The theory, described in the journal Nature Catalysis, could open new design possibilities for new catalysts with new capabilities.

COLUMBUS, Ohio--You can wear an exoskeleton, but it won't turn you into a superhero.

That's the finding of a study in which researchers tested a commercially available exoskeleton--a mechanical arm attached to a harness--that's typically worn by workers to help them carry heavy objects hands-free.

In the journal Applied Ergonomics, the researchers report that that the device relieved stress on the arms just as it was supposed to--but it increased stress on the back by more than 50 percent.

In a recent study published in Science, researchers at ICFO - The Institute of Photonic Sciences in Barcelona, Spain, along with other members of the Graphene Flagship, reached the ultimate level of light confinement. They have been able to confine light down to a space one atom, the smallest possible. This will pave the way to ultra-small optical switches, detectors and sensors.

Ljubljana, Slovenia - 20 April 2018: Faster walking patients with heart disease are hospitalised less, according to research presented today at EuroPrevent 2018, a European Society of Cardiology congress, and published in the European Journal of Preventive Cardiology.1,2

The three-year study was conducted in 1,078 hypertensive patients, of whom 85% also had coronary heart disease and 15% also had valve disease.

CAMBRIDGE, MASS.--Two and a half years ago, a team of researchers led by groups at MIT, the University of California at Berkeley, and Boston University announced a milestone: the fabrication of a working microprocessor, built using only existing manufacturing processes, that integrated electronic and optical components on the same chip.

A Dutch-Texan team found that most Houston-area drowning deaths from Hurricane Harvey occurred outside the zones designated by government as being at higher risk of flooding: the 100- and 500-year floodplains. Harvey, one of the costliest storms in US history, hit southeast Texas on 25 August 2017 causing unprecedented flooding and killing dozens. Researchers at Delft University of Technology in the Netherlands and Rice University in Texas published their results today in the European Geosciences Union journal Natural Hazards and Earth System Sciences.

For the first time, scientists have successfully created optically active, chiral gold nanoparticles using amino acids and peptides. Many chemicals significant to life have mirror-image twins (left-handed and right-handed structures), a characteristic that is conventionally called chirality. This study describes how chirality, which is typically observed in organic molecules, can be extended to three-dimensional metallic nanostructures. This newly discovered synthesis method was described in Nature (April 19th) and was featured on the cover.
