Universal Class

Universal Class is a great resource that the Downers Grove Public Library provides for Downers Grove patrons.  Universal Class consists of “self-directed online classes on over 500 topics.”  Each class that you complete will give you a certificate of course completion and CEUs (Continuing Education Units).  It’s structured just like an online college course, giving you 6 months to complete the course with an instructor grading your assignments and exams.

Bitcoin: the Future of Online Business?

You’ve all heard of Euros, Pesos, Rubles, Rupees, and of course Dollars. But have you heard of the newly created digital currency called Bitcoin?

Bitcoin is a decentralized (not created by any one government) peer-to-peer, electronic currency that only exists online. There is no central body controlling the Bitcoin network, and it's managed and regulated by its users.

Electronic Tattoos: More than just Body Art

     Researchers at the University of Illinois have developed an electronic tattoo that can be “printed” directly on the body and can be worn for an extended period while doing normal daily activities. This device would track patients' symptoms by measuring heart rate and temperature, strain and hydration and then sending the information back to a doctor. E-tattoos like this could be used to track health and monitor healing near the skin’s surface, as in the case of monitoring surgical wounds after a patient leaves the hospital.  

Cancer Detecting Goggles

Advancements in medical technology continue as the latest instrument used in surgery are goggles that are able to detect cancer cells. Still in the trial phase, Washington University doctors created a set of goggles that are able to detect cancer cells with the use of dye. By injecting a patient with dye, the goggles allow a doctor to be able to distinguish between cancer cells which through the goggles light up due to the dye, and healthy tissue. This technology has the ability to save many lives of patients because the goggles can show a doctor how far the cancer has progressed.

3-D Osteoid Medical Cast

For anyone who has broken a bone, you understand how uncomfortable and inconvenient wearing a cast may be. Now with 3D printing a Turkish designer named Deniz Karasahin has created the “Osteoid Medical Cast”. Unlike the plaster casts, the Osteoid Medical Cast has ventilation holes that help with the weight, itchiness, and smell. The holes are also for a low- intensity ultrasound machince to be connected to the cast to aid in healing.

Scientists Try Using a 3-D Printer to Build a Human Heart

Next time that you print something from your computer, think about the fact that research is being done to print an actual human heart from a 3-D printer!

Scientists hope that they will be able to use a 3-D printer to create a new heart for a patient with their own cells. They could then transplant it into the patient, and because the heart was ‘built’ from the patient’s own cells, he or she would not need anti-rejection drugs.

The Heartbleed Bug - What You Need to Know

Security researchers have recently discovered a serious bug, nicknamed Heartbleed,  that affects nearly two-thirds of all websites and could be one of the biggest security threats ever seen on the Internet. If you have logged into any of the affected sites over the past two years, your account information could be compromised, allowing cybercriminals to snap up your credit card information or steal your passwords.
