Buruli ulcer is not an affliction you would like anyone to contract. Caused by Mycobacterium ulcerans, it produces a toxin which necrotizes tissue and hampers immune response. Up to 6000 cases are reported annually to the World Health Organization from 15 countries. Though 80 percent of cases can be cured by antibiotics if caught early, late reporting is typical, leading to a high proportion of permanent disability.
Smartphones have revolutionized the way we work, play, communicate and carry out our day to day lives. Recently, researchers discovered a surprising and potentially life-saving application for this technology: early earthquake detection. This unconventional pocket detector could provide precious seconds for people to take shelter or for utilities to implement emergency shutdown procedures.
The presence of oxygen in the Earth’s atmosphere is a critical component to life as we know it. But how did our atmosphere come into existence? What events created the oxygen rich air that we breathe? Scientists think that the answer lies in the lowliest of creatures; creatures that we don’t even notice unless we pull back the muck and ‘dig deep’.
The Millennials are often called the “Selfie-generation.” They pride themselves on using those selfies to create their personal online brand — defining who they are, what they like and what they stand for. But even if you aren’t a Millennial, it’s likely that you use Facebook, Twitter, LinkedIn or Instagram and you’ve probably taken at least a few selfies. While some credit the selfie as pure narcissism, others consider them a form of self-expression and a way to control how others perceive us online. But what do those selfies really say about you? How do others perceive you based on your social media photos?
There’s no denying that grizzly bears are huge animals and gain even more weight when getting ready to hibernate (they can gain 100 pounds before hibernation). If humans don’t take care of themselves, it can lead to weight gain or other serious issues such as diabetes. Grizzly bears can stuff their stomachs and then sleep like there’s no tomorrow knowing that they don’t have to worry about their diet or diabetes. New research, published in the August 2014 issue of Cell Metabolism, sheds some light into this seemingly unfair phenomenon.
Every great student requires a great teacher. The fields about which we have written, and the fields about which we will continue to write, all encourage students to begin taking STEM courses in high school. These STEM courses need good teachers to teach them. If learning about science, technology, engineering, and mathematics is what you want to do in college, and then you want to pass that knowledge on to future generations, consider becoming a STEM teacher.
It’s unsettling when a strong rain storm brings down power lines and leave entire neighborhoods without electricity. But, what if you could simply plug a cell phone into the window and let it charge as the storm rages on outside? Continue reading “Smart Window Converts Weather into Electricity” »
The room is quiet and the only sound is that of pencils scratching answers on papers as everyone focuses on the exam. Then the silence is broken by the unmistakable sound of someone cracking their knuckles. Scientists now know why knuckles make that distinct popping sound when cracked. Continue reading “MRI Scan Reveals Why Knuckles Crack” »
Straight or Curly? Why won’t this frizzy hair go away? I want to wear lipstick but what color is right for me? I put on deodorant every morning, but I’m still a sweaty mess by noon. No one understands my dilemmas and my reputation is everything.

Dinosaurs first appeared during the Triassic Period of the Mesozoic Era over 245 to 208 million years ago and dominated the planet for 135 million years. Among the largest were the herbivorous sauropods known for their long necks and tails and immense size. For generations of children, the most famous of these giants was the Brontosaurus, or “thunder lizard.” Continue reading “The Name Game: Brontosaurus vs. Apatosaurus” »
