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…

Pressure sensor can identify early stages of flat feet

It records the data from mobile sensors placed on an insole of a shoe. Later, it is being sent via Bluetooth connection to a computer for visualization. Credit: KTU A team of researchers at Kaunas University of Technology (KTU) have designed a device for measuring pressure on human feet. Its applications include pediatric illnesses and monitoring the physical condition of professional athletes. The most mechanical pressure is endured by the feet, which bear all of a person’s weight while walking.…

Mizzou summer program gives KAU students real-world experience

An international program offering hands-on, interdisciplinary projects that prepare students for real-world issues facing engineers in their home country is sure to attract high-quality attendees. And when it offers exposure to new cultures and novel educational methods, it attracts the best and brightest. In its fourth year, the University of Missouri’s King Abdulaziz University Internship for Engineering students has the formula down pat. The six week-long internship saw 24 students from King Abdulaziz University (KAU) in Jeddah, Saudi Arabia, come…

Somersaulting simulation for jumping bots

A simulation (top row) and real-world experiment (bottom row) match for the same jumping mechanism designed to flip over a wall and land right side up on the other side. This simulation was generated by a new method that accurately predicts the real-world behavior of such mechanisms undergoing large-deformations, high-speed dynamics, frictional contact and impact. It does so at speeds fast enough to now be used in automated design algorithms that must rapidly, yet accurately, predict whether a design will…
