Set goals at an early age
March 20, 2019
Jerry Ross, 71, was in Class 4 when he decided that he wanted to join his country’s space programme. Just nine years later, in 1980, he was selected as an astronaut. A retired US Air Force officer, Ross intensively worked in the area of space walks or EVAs (extra-vehicular activity), and as a result, the former NASA astronaut became the first person ever to fly seven times to space. During his career with NASA, he logged more than 1,393 hours in space. To document several such experiences for his granddaughters and to encourage the young to figure out what they would like to do in their life early on, he wrote his first book in 2013, Spacewalker: My Journey in Space and Faith as NASA's record-setting frequent flyer.
Veteran US astronaut cautions against space travel, says it’s a risky proposition
March 13, 2019
Most people are fired up about space flights — going up and coming down — but there are some harsh ground realities, cautions veteran US astronaut Jerry Ross. For most corporate Earthlings, ‘hang in there’ could have a world of different meanings. For Jerry Ross, astronaut and a member of seven US space shuttle missions, it meant adjusting to the darkness of the universe while floating in space.
Your body is your internet -- and now it can't be hacked
March 12, 2019
Someone could hack into your pacemaker or insulin pump and potentially kill you, just by intercepting and analyzing wireless signals. This hasn't happened in real life yet, but researchers have been demonstrating for at least a decade that it's possible. Before the first crime happens, Purdue University engineers have tightened security on the "internet of body." Now, the network you didn't know you had is only accessible by you and your devices, thanks to technology that keeps communication signals within the body itself.
India's farmers burdened with 'choice overload'
March 2, 2019
Faced with choice overload, and without a reliable measure to understand what a 'good yield' means, Indian farmers tend to follow rich villages when making important agricultural decision, scientists say. "Consumer scientists call this 'choice overload.' When you step into a supermarket and there are 70 types of mustard to buy, it becomes a stressful situation and people no longer want to deal with making that decision," said Andrew Flachs, an environmental anthropologist at Purdue University in the US.
5G, 4G Networks Have Flaws That Allow Location Tracking, Phone Snooping: Report
February 26, 2019
A new research paper outlines security flaws in 4G and 5G networks that allow hackers to eavesdrop on phone calls and track users' locations using their smartphones. According to one of the co-authors Syed Rafiul Hussain, the attack can be carried out by anyone who is well versed with cellular paging protocols. Researchers claim that these new attacks can even defeat newer protections that have been put into place claiming ‘better security'. The attacks affect major US carriers, and Europe and Asia carriers are also vulnerable. Co-authors of this new research paper are Ninghui Li, Syed Rafiul Hussain, and Elisa Bertino from Purdue University, and Mitziu Echeverria and Omar Chowdhury from University of Iowa.
High-altitude balloon makes space more accessible to micro-satellites
February 23, 2019
The test launch of the “rockoon” in December was a success. Leo Aerospace is seeking to make space more accessible for those wanting to deploy small satellites. A startup that plans to use high-altitude balloons to deploy rockets has successfully fired a test launch, moving closer to its goal of helping end the backlog of micro-satellites that wait months or longer to “hitch” a ride on larger rockets.
Holostream: Relieving the pain and time of sharing 3D video content
February 23, 2019
You might have a music video – and a Purdue University professor – to thank for making a future trip to see the doctor much easier. Song Zhang, an associate professor of mechanical engineering in Purdue’s College of Engineering, was working on a music video and knew there had to be an easier way to share 3D content.
Super Flexible Nano-materials to Make Fuel Cell Cars Cheaper
February 22, 2019
Scientists have developed a new method of increasing the reactivity of ultrathin nanosheets, just a few atoms thick, an advance that can make fuel cells for hydrogen cars cheaper in the future. The research, published in the journal Science, offers promise towards faster, cheaper production of electrical power using fuel cells, and also of bulk chemicals and materials such as hydrogen. "We are essentially using force to tune the properties of thin metal sheets that make up electrocatalysts, which are part of the electrodes of fuel cells," said Jeffrey Greeley, a professor at Purdue University in the US.
Enlarged Prostate Could Actually Be Stopping Tumor Growth, Simulations Show
February 5, 2019
For men older than about 60, an enlarged prostate means feeling the urge to make a pit stop way too often throughout the day. But a new study shows that if these men also happen to have prostate cancer, the larger prostate actually impedes tumor growth. “It’s already known that forces and stresses have an impact on tumor growth, and that patients with enlarged prostates tend to have slower cancer growth, but it wasn’t known why,” said Hector Gomez, associate professor of mechanical engineering at Purdue University, who builds models and simulations for understanding tumor growth, cellular migration and blood flow.
When Sanjay Reddy, Habil Khorakiwala bonded over alma mater Purdue University
January 31, 2019
They may be thousands of miles away from the university where they spent their formative years, but nothing diminishes the love which the Purdue University alumni in India have for their alma mater. They simply couldn’t miss a chance to hear some of the illustrious graduates of the American university and bond over stories from the good old days. At the International Ideas Festival hosted a couple of weeks back in Mumbai, Purdue alumni in India gathered to hear about big ideas.
