Nashville School Uses Augmented Reality
Posted by Karen Hurst in categories: augmented reality, education
Nice
J.E. Moss Elementary School, a Title I school in Nashville, TN, has adopted an augmented reality program to help improve reading skills in one of its kindergarten classes.
Letters alive, a supplemental reading software kit from Alive Studios, has aided teacher Greg Smedley-Warren and boosted his kindergarten class’ literacy scores above all the other kindergarten classrooms in his school, according to a prepared statement. His class includes several ELL and “at risk” students.

Lele flagella motor research develops novel insights in cellular mechanics
Posted by Karen Hurst in categories: biotech/medical, electronics, engineering, nanotechnology
Using bacteria to aid in the design of superior biomedical implants capable of resisting colonization by infectious bugs.
Dr. Pushkar Lele, assistant professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, is developing novel insights in cellular mechanics with bacteria to aid in the design of superior biomedical implants capable of resisting colonization by infectious bugs. Lele’s group also focuses on unraveling the fundamental principles underlying interactions in biological soft-matter to build bio-nanotechnology-based molecular machines. Lele’s lab currently focuses on a unique electric rotary device found in bacteria — the flagellar motor.
According to Lele, it is well established how motile bacteria employ flagellar motors to swim and respond to chemical stimulation. This allows bacteria to search for nutrients and evade harmful chemicals. However, in his recent work, Lele has now demonstrated that the motor is also sensitive to mechanical stimulation and identified the protein components responsible for the response. Sensing initiates a sensitive control of the assemblies of numerous proteins that combine to form the motor. Control over motor assemblies facilitates fine-tuning of cellular behavior and promotes chances of survival in a variety of environments.

US military agency DARPA: We want biometric tech to ID individual hackers

Of course; makes sense.
DARPA hopes it can ‘fingerprint’ individual cyberattackers and build a picture of their handiwork over time.

‘Super males’ emerge from male-dominated populations, study finds
Posted by Karen Hurst in category: futurism
Science proving that Alpha males still capture their mates — glad to see how science has gone backwards.
Males who evolve in male-dominated populations become far better at securing females than those who grow up in monogamous populations, according to new research into the behaviour of fruit flies at the University of Sheffield.
The study, led by Dr Allan Debelle and Dr Rhonda Snook in the University’s Department of Animal and Plant Sciences, looked at the mating patterns of fruit flies after they evolved for 100 generations in either polyandrous populations (where several males have to compete for a single female) and monogamous populations (where each male has access to only one female).

Use Your Brain. Ditch Your Fitness Tracker
Posted by Karen Hurst in categories: health, neuroscience, wearables
Interesting approach.
If you’re at all interested in your health, it’s likely you’ve joined the 20 percent of Americans who’ve incorporated fitness trackers into their daily ensemble. From monitoring steps and daily activity to sleep, an ever-growing number of devices are tracking and analyzing our body’s data in an effort to make us better.
But how good is this tracking? Despite noble intentions, the scientific reality is that much of the data these trackers provide is insufficient and inaccurate — and in turn, are not as effective as they promise.

Humans Are Fatter Than Primates, But It Fuels Our Bigger Brains
Posted by Karen Hurst in categories: energy, food, neuroscience
Left hemisphere of J. Piłsudski’s brain, lateral view.
A new study has found that a faster metabolism is the main reason that humans were able to evolve bigger brains than other closely related apes. Humans burned 635 more calories per day than gorillas, and a whopping 820 more calories per day than the orangutans in the study.
Although the study findings seem promising, more research on the issue is required since the research was performed only on adults.

Gene replacement therapy offers viable treatment option for fatal disease
Posted by Karen Hurst in categories: biotech/medical, genetics
New cure for SMA?!
Spinal muscular atrophy (SMA) is a disease that causes progressive degeneration in the nerve cells that control muscles, thereby causing muscle weakness and eventually death. SMA affects approximately 200,000 people in the U.S., often children. Now, researchers at the University of Missouri are studying a subtype of SMA, spinal muscular atrophy with respiratory distress type 1 (SMARD1), and have developed a gene replacement therapy that can be used to treat and control the disease in the future.
SMARD1 is a rare genetic condition with high mortality rate that develops primarily between the ages of six weeks and six months. The condition targets the spinal cord and leads to atrophy of body muscles and paralysis of the diaphragm, which is responsible for breathing. As the disease progresses, children with a SMARD1 diagnosis become paralyzed and require continuous artificial ventilation. The average life expectancy of a child diagnosed with SMARD1 is 13 months. Currently, there is no cure or effective treatment for this disease.
“Monogenic diseases like SMARD1, a disease that is caused by one gene, are ideal for gene therapy since the goal of the therapy is to replace the missing or defective gene,” said Chris Lorson, an investigator in the Bond Life Sciences Center and a professor of veterinary pathobiology. “Our goals for this study were to develop a vector that would improve the outcomes of the disease and for the vector to be effective in a single dose.”

Navigate your smartwatch

New tech from Carnegie Mellon makes it much easier to play ‘Angry Birds’ on your wrist.
Smartwatches walk a fine line between functionality and fashion, but new SkinTrack technology from Carnegie Mellon University’s Future Interfaces Group makes the size of the screen a moot point. The SkinTrack system consists of a ring that emits a continuous high-frequency AC signal and a sensing wristband that goes under the watch. The wristband tracks the finger wearing the ring and senses whether the digit is hovering or actually making contact with your arm or hand, turning your skin into an extension of the touchscreen.
