Startup develops animal detection system to prevent roadkill

Through means of sensors e transmitters, an animal detection system aims to feed message boards for drivers hundreds of meters before wild specimen can cross the road. Credit: Fernanda Delborgo Abra / ViaFauna Wildlife road accidents threaten endangered species, but roadkill incidents also jeopardize drivers and passengers, and may oblige road operators to disburse costly compensation. Considering that domestic animals such as horses, cattle and dogs are just as likely to be victims, the scale of the problem is apparent.…

Researchers design the building blocks of synthetic muscle using computational method

Muscle is made up of molecular motors called myosin that form complex combinations to perform specific functions, such as powering muscle contraction. Synthetic myosin could one day be used in regenerative medicine and robotics. Credit: Paul Egan/College of Engineering, Carnegie Mellon University Each time you flex your bicep, millions of molecular motors work together in a complex process inside your muscle. These motors—called myosin—are chemically-powered proteins. Combinations of them perform different muscular functions like maintaining a heartbeat or bearing weight. …

Researchers develop spectroscopic ‘science camera’ system for smartphones

Credit: Micro and Nanotechnology Lab, University of Illinois at Urbana-Champaign The latest versions of most smartphones contain at least two and sometimes three built-in cameras. Researchers at the University of Illinois would like to sell mobile device manufactures on the idea of adding yet another image sensor as a built-in capability…

Key process to be modernized in production of life-saving drugs, food preservation

Research scientist Nithin Raghunathan works in the LyoHUB Lyophilization Technology Demonstration Facility at the Birck Nanotechnology Center at Purdue University. Credit: Purdue University image/Erin Easterling A consortium of experts is working to modernize a process that is used in making a wide range of products, from freeze-dried space foods to life-saving wonder drugs. The process, called “lyophilization,” removes water at low temperature and pressure. Lyophilization is needed for products that would be damaged if they were dried by heating, but…

The Story of Two Outages

Over the last two days, Cloudflare observed two events that had effects on global Internet traffic levels. Cloudflare handles approximately 10% of all Internet requests, so we have significant visibility into traffic from countries and networks across the world. On Tuesday, September 5th, the government of Togo decided to restrict Internet access in the country following political protests. The government blocked social networks and rate-limited traffic, which had an impact on Cloudflare. This adds Togo to the list of countries…

PupilScreen aims to allow parents, coaches, medics to detect concussion, TBIs with a phone

The UW researchers initially tested PupilScreen with a 3-D printed box that controls the eye’s exposure to light. They are now training their deep learning algorithms to produce similar results with the smartphone camera alone. Credit: Dennis Wise/University of Washington University of Washington researchers are developing the first smartphone app that is capable of objectively detecting concussion and other traumatic brain injuries in the field: on the sidelines of a sports game, on a battlefield or in the home of…

High-frequency chip brings researchers closer to next generation technology

A new high-frequency chip developed at UC Davis uses a phased array to transmit and receive millimeter waves. The technology could increase data transfer rates. In this photo, a prototype chip is held by graduate student Hossein Jalili. Credit: Maria Ines Perez-Vargas/UC Davis novel, high-frequency electronic chip potentially capable of transmitting tens of gigabits of data per second—a rate that is orders of magnitude above the fastest internet speeds available today—has been developed by engineers at the University of California,…

Build Your Data Science Team Like a Swiss Army Knife

Though far from a reality in many fields, it is now widely accepted that building a diverse team will make your organization more successful. Many insightful articles and research studies have driven this point home, focusing on diversity axes like gender, ethnicity, culture, age, orientation, and physical ability. Those dimensions are all important. If you participate in the hiring process for your team, and haven’t taken the time to read about why diversity is critical, you absolutely must. Like, now.…

Greening the concrete jungle—how to make environmentally friendly cement

With some tweaks to the recipe, cement and concrete can be made kinder to the planet. Credit: Postman Photos/Shutterstock.com Cement is the world’s most widely used material apart from water, largely because it is the key ingredient in concrete, the world’s favourite building material. But with cement’s success comes a huge amount of greenhouse emissions. For every tonne of cement produced in Australia, 0.82 tonnes of CO₂ is released. That might not sound like much, especially when compared with the…

Hacker Trackers camp teaches high schoolers cyber security skills

The four-day-long Hacker Trackers camp, led by Assistant Professor Prasad Calyam, gives high school students training and development in Python coding and cyber security.
