New Genetic Engineering Technique Could Help Design, Study Biological Systems

Djuranovic-Arthur-for-web.jpg

A new technique helps biologists tinker with genes, whether the goal is to turn cells into tiny factories churning out medicines or to study their effects on human health. The technique allows scientists to precisely regulate how much protein is produced from a particular gene.

Brain Stimulation Used Like a Scalpel to Improve Memory

TMSimageSlider.jpg

Northwestern Medicine scientists showed for the first time that non-invasive brain stimulation can be used like a scalpel, rather than like a hammer, to cause a specific improvement in precise memory.Precise memory, rather than general memory, is critical for knowing details such as the specific color, shape and location of a building you are looking for, rather than simply knowing the part of town it’s in.

New Low-Cost Technique Converts Bulk Alloys to Oxide Nanowires

fig1-small.jpg

A simple technique for producing oxide nanowires directly from bulk materials could dramatically lower the cost of producing the one-dimensional (1D) nanostructures. That could open the door for a broad range of uses in lightweight structural composites, advanced sensors, electronic devices – and thermally-stable and strong battery membranes able to withstand temperatures of more than 1,000 degrees Celsius.

Chemists Cook Up New Nanomaterial and Imaging Method

A team of chemists led by Northwestern University’s William Dichtel has cooked up something big: The scientists created an entirely new type of nanomaterial and watched it form in real time — a chemistry first.“Our work sets the stage for researchers interested in studying the fundamental properties of interesting materials and applied systems, such as solar cells, batteries, sensors, paints and drug delivery systems,” said Dichtel, the Robert L.

Older Adults with Arthritis Need Just 45 Minutes of Activity Per Week

Older adults who suffer from arthritis need to keep moving to be functionally independent. But in an examination of a goal that is daunting for most of this aging population, a new Northwestern Medicine study found that performing even a third of the recommended activity is beneficial.

New Genital Herpes Vaccine Candidate Provides Powerful Protection in Preclinical Tests

Approximately 500 million people around the world are infected with the genital herpes virus known as herpes simplex virus 2 (HSV2). A vaccine that could bring an end to this global pandemic is needed desperately, yet no candidate vaccine has ever performed well in clinical trials. Now scientists in the Perelman School of Medicine at the University of Pennsylvania have shown that a new type of vaccine provides powerful protection in standard guinea pig and monkey models of HSV2 infection.

What Causes Sleepiness When Sickness Strikes

It’s well known that humans and other animals are fatigued and sleepy when sick, but it’s a microscopic roundworm that’s providing an explanation of how that occurs, according to a study from researchers at the Perelman School of Medicine at the University of Pennsylvania. A study published this week in eLife reveals the mechanism for this sleepiness.

Chip-Sized, High-Speed Terahertz Modulator Raises Possibility of Faster Data Transmission

Modulator.jpg

Tufts University engineers have invented a chip-sized, high-speed modulator that operates at terahertz (THz) frequencies and at room temperature at low voltages without consuming DC power. The discovery could help fill the “THz gap” that is limiting development of new and more powerful wireless devices that could transmit data at significantly higher speeds than currently possible.

The Philadelphia Pediatric Medical Device Consortium (PPDC) has announced seed grants of $50,000 each to three companies developing medical devices for children. The child-sized devices are a powered orthotic arm brace that amplifies weak nerve signals, a hand-operated rapid blood delivery system for emergency situations and a device that gradually corrects deformed ears in babies.

First Cell Culture of Live Adult Human Neurons Shows Potential of Brain Cell Types

EberwineCellReportsHumanNeurons.jpg

Studying brain disorders in people and developing drugs to treat them has been slowed by the inability to investigate single living cells from adult patients. In a first-of-its-kind study, researchers were able to grow adult human neurons donated from patients who had undergone surgery. From these cell cultures, they identified more than five brain cell types and the potential proteins each cell could make.
