newsweek:

Will the problem of memory loss one day be forgotten? In the next few weeks the Pentagon’s research-and-development arm will announce a plan to fund the creation of a brain implant to help wounded soldiers recover their mental faculties.

The research could also impact the millions of civilians affected by Alzheimer’s and other degenerative brain disorders. We know in broad outline what it takes to lay down a memory.

Throughout the years every single one of our experiences—from a major life event to the humdrum—has made and broken some of the vast network of connections that carry signals between the neurons in our brains: it is these patterns of connections that are central to our identity, our skills and how we think.

But traumatic brain injuries (TBI) can damage a person’s ability to retrieve memories, or to form or retain memories of new experiences. And since 2000, there have been almost a quarter million U.S. service personnel who have been diagnosed with TBI. That’s why the U.S. Defense Advanced Research Projects Agency (DARPA) has launched the Restoring Active Memory (RAM) program. the RAM program will seek to find new methods for analysis and decoding of the neural networks to understand how to reverse damage caused by a brain injury.

First, DARPA will try to create an implant that might bridge gaps in an injured brain, in order to help the injured overcome the loss of motor memories. Motor memories are those formed out of repetition—for example, when riding a bike or developing a one-handed tennis backhand.

Wormlike Motion Lets Gels Wiggle Through Water


Next time you spot an earthworm sliding through fresh dirt, take a closer look. What you’re seeing is an organic movement called peristaltic locomotion that has been meticulously refined by nature.



Jarod Gregory, an undergraduate student in the Univ. of Cincinnati’s College of Engineering and Applied Science, used a worm’s contracting and expanding motion to provide a way for gels to swim in water.

Could An STD Cause Prostate Cancer?

Trichomoniasis is the most common STD in the world, and people have been finding links between the infection and prostate cancer! Tara and Laci are here to report on this finding, and also discuss research showing that dogs are able to sniff out patients with prostate cancer!

Observatory Helps Explain ‘Red and Dead Galaxies’


NASA’s Chandra X-ray Observatory has shed new light on the mystery of why giant elliptical galaxies have few, if any, young stars. This new evidence highlights the important role that supermassive black holes play in the evolution of their host galaxies.



Because star-forming activity in many giant elliptical galaxies has shut down to very low levels, these galaxies mostly house long-lived stars with low masses and red optical colors. Astronomers have therefore called these galaxies “red and dead.”

Nanotubes Used to Track Movement Inside Cells


Chemical engineers from Rice Univ. and biophysicists from Georg-August Universität Göttingen and the VU Univ. Amsterdam have successfully tracked single molecules inside living cells with carbon nanotubes. Through this new method, the researchers found that cells stir their interiors using the same motor proteins that serve in muscle contraction. The study, which sheds new light on biological transport mechanisms in cells, was published in Science.



The team attached carbon nanotubes to transport molecules known as kinesin motors to visualize and track them as they moved through the cytoplasm of living cells.

Equivalence Principle

Paul Andersen explains how inertial mass and gravitational mass are equivalent. He shows you too simple methods for calculated individual inertial mass and gravitational mass. Albert Einstein used this principle to build his general theory of relativity.

Evolution Picked Brains Over Brawn


Compared to many other species in the animal kingdom, human muscles are relatively weak. A team of researchers have delved into the evolutionary mechanisms that have caused humans to prioritize brain development over pure muscle power.



While humans are almost certainly one of the smartest species to have ever walked the planet, Homo sapiens may have paid a steep price for all of that added brain power. While humans are more intelligent than other animals, they have weaker muscles. New research conducted by scientists from the Chinese Academy of Sciences (CAS) in Shanghai shows that all of the energy put into brain development may have led to decreased development in human musculature. The researchers published their findings in the online journal PLOS Biology.
