Researchers have used gene editing to completely eliminate populations of mosquitoes in the lab.
The team tested their technique on the mosquito Anopheles gambiae, which transmits malaria.
They altered part of a gene called doublesex, which determines whether an individual mosquito develops as a male or as a female.
Researchers at Syracuse University, working with collaborators at the University of Wisconsin (UW)-Madison, have developed a new technique for measuring the state of quantum bits, or qubits, in a quantum computer.
Their findings are the subject of an article in Science magazine, which elaborates on the experimental efforts involved with creating such a technique.
The Plourde Group—led by Britton Plourde, professor of physics in Syracuse’s College of Arts and Sciences (A&S)—specializes in the fabrication of superconducting devices and their measurement at low temperatures.
Adequate supply of blood and structural and functional integrity of blood vessels are key to normal brain functioning. On the other hand, cerebral blood flow shortfalls and blood–brain barrier dysfunction are early findings in neurodegenerative disorders in humans and animal models. Here we first examine molecular definition of cerebral blood vessels, as well as pathways regulating cerebral blood flow and blood–brain barrier integrity. Then we examine the role of cerebral blood flow and blood–brain barrier in the pathogenesis of Alzheimer’s disease, Parkinson’s disease, Huntington’s disease, amyotrophic lateral sclerosis, and multiple sclerosis. We focus on Alzheimer’s disease as a platform of our analysis because more is known about neurovascular dysfunction in this disease than in other neurodegenerative disorders. Finally, we propose a hypothetical model of Alzheimer’s disease biomarkers to include brain vasculature as a factor contributing to the disease onset and progression, and we suggest a common pathway linking brain vascular contributions to neurodegeneration in multiple neurodegenerative disorders.
Five years after he was paralysed in a snowmobile accident, a man in the US has learned to walk again aided by an electrical implant, in a potential breakthrough for spinal injury sufferers.
A team of doctors at the Mayo Clinic in Minnesota say the man, using a front-wheeled walker, was able to cover the equivalent of the length of a football pitch, issuing commands from his brain to transfer weight and maintain balance—all previously thought impossible for paralysed patients.

Errors: I made an off hand comment about adding efficiencies in the video without thinking. This is obviously incorrect, but the final calculation does in fact multiply the efficiencies.
Apparently, amyloid beta drives its own production in a vicious circle.
In a study at King’s College London, scientists have shown that a vicious circle in which the ill-famed amyloid-beta protein stimulates its own production might be a key factor in the etiology of neurodegeneration in Alzheimer’s disease; furthermore, a drug known as fasudil seems to be effective against amyloid-beta in a mice model of the disease [1].
