Engineering on a blue streak — ScienceDaily

A pair of engineers at the University of Delaware has developed a process to form interwoven polymer networks more easily, quickly and sustainably than traditional methods allow. Their secret ingredient? Blue light. Abhishek Shete, graduate research assistant in materials science and engineering, and Christopher Kloxin, assistant professor in materials science and engineering and chemical and biomolecular engineering, describe their method in a paper featured on the cover of the 24th issue of Polymer Chemistry. The paper is titled “One-pot blue-light…

What’s in your rum? Flavor scientists create a lexicon of terms to describe nuances of popular beverage — ScienceDaily

Aficionados use words like “oaky” to describe some wines, or “hoppy” when talking about certain beers. But for rum — a product with over 1,000 different varieties — putting the words together to describe what imbibers are smelling and tasting is a bit more difficult. Consequently, researchers at the University of Illinois were interested in creating a rum flavor lexicon, but needed to find a way around the biggest problem with tasting rum — sensory fatigue. Having a set of…

The Case Against Kotlin – Pinterest Engineering – Medium

Ryan Cooke | Android Engineer, Core Experience It’s a big decision to start using Kotlin in your app. Right now, Kotlin may be nearing the “Peak of Inflated Expectations” in the Hype Cycle. You can find endless quality blogs, podcasts and videos on the virtues of Kotlin. For this post let’s assume you understand the benefits of it. Here we’ll look in-depth at the challenges Android developers will likely face with Kotlin and offer solutions. There are real costs to…

Newly discovered biomarkers may lead to promising diagnostic tool for Alzheimer’s — ScienceDaily

Diagnosing Alzheimer’s disease and determining a patient’s prognosis is an inexact business, and that stands in the way of better personalized care and advances in treatment. A new study from The Ohio State University has identified a potential new way of confirming the disease and predicting a patient’s outlook. First, the team of researchers discovered new physical biomarkers that could help pinpoint a diagnosis — changes to proteins found in the spinal fluid and blood of patients. In particular, as…

Goal is to reduce unnecessary use of antibiotics, combat antibiotic resistance — ScienceDaily

Antibiotics are lifesaving drugs, but overuse is leading to one of the world’s most pressing health threats: antibiotic resistance. Researchers at the University of Rochester Medical Center are developing a tool to help physicians prescribe antibiotics to patients who really need them, and avoid giving them to individuals who don’t. Scientists from the University’s National Institutes of Health-funded Respiratory Pathogens Research Center identified 11 genetic markers in blood that accurately distinguished between viral and bacterial infections (antibiotics help us fight…

Application DDoS In Microservice Architectures By Scott Behrens and Bryan Payne Introduction We’d like to introduce you to one of the most devastating ways to cause service instability in modern micro-service architectures: application DDoS. A specially crafted application DDoS attack can cause cascading system failures often for a fraction of the resources needed to conduct a more traditional DDoS attack. This is due to the complex, interconnected relationships between applications. Traditional DDoS attacks focus on exhausting system resources at the…

Open Sourcing Jaqen, A Tool For Developing DNS Rebinding PoCs

Editor’s note: Members of the information security team at LinkedIn have an opportunity to work on research topics under a well-defined framework that allows them to evaluate new products and technologies, as well as explore the related threat surface. The team strives to find new and innovative ways to help simplify and strengthen security and contribute back to the community where possible to do so. In early 2017, Luke Young had the opportunity to make use of this framework and…

Crops that kill pests by shutting off their genes — ScienceDaily

Plants are among many eukaryotes that can “turn off” one or more of their genes by using a process called RNA interference to block protein translation. Researchers are now weaponizing this by engineering crops to produce specific RNA fragments that, upon ingestion by insects, initiate RNA interference to shut down a target gene essential for life or reproduction, killing or sterilizing the insects. The potential of this method is reviewed in Trends in Biotechnology‘s upcoming special issue on environmental biotechnology.…

No one knew just how many Ubers and Lyfts were out there—until now

Northeastern researchers Alan Mislove and Christo Wilson created a program that works to determine the volume of drivers for these ride-hailing services in San Francisco, collecting data that are typically held closely by both companies. Credit: Northeastern University In urban areas—and in not so urban areas—around the globe, Uber and Lyft are ubiquitous. But knowing just how many are out there at a given time is a problem that’s eluded municipal transportation officials since the ride-hailing services burst onto the…

Using magnetic resonance to evaluate food quality

The applications and benefits of nuclear magnetic resonance (NMR) in medicine are well known, but the technology is also used in other areas such as agribusiness, where its applications include quality analysis of seeds and other products of animal and plant origin. NMR has recently reached the retail commerce sector, where it expedites the assessment of meat and fruit quality in supermarkets. Fine Instrument Technology (FIT), a Brazilian company based in São Carlos (São Paulo State, Brazil), has developed a…
