The folks at Backyard Brains have developed a device called RoboRoach that lets you control the movement of a cockroach with your iPhone! With the RoboRoach you can control a single insect, but what if you had control of an entire swarm? One researcher is trying to develop such technology to aid in search-and-rescue missions.

Scientists still debate the exact function of sleep, with some arguing that it aids our memory, while others argue that it helps to conserve energy, and still other argue that it is needed to discharge our emotions. Well, a new study published in Science presents data suggesting that during sleep harmful toxins are cleared from our brains, which might prevent diseases like Alzheimer’s.

The light show at the Mickey Hart Band concert is part science, part art. Mickey Hart, best known as the percussionist for the Grateful Dead, wears an EEG cap while he plays which powers the light show for concert. Read more at NPR’s coverage: This is Musician Mickey Hart’s Brain on Music
After being hospitalized for 2 months, Kali Hardig, 12, gets to go home after recovering from amebic meningoencephalitis which health officials believe she contracted at a Little Rock, Ark., waterpark in July. She is only the third known survivor of the deadly infection in the last 50 years. Read more at Daily News: Arkansas girl survives brain-eating amoeba
Using fMRI, scientists have located a part of the brain – just above each of the ears – that responds to quantities. It allows us to look at objects and quickly tell how many there are. This ability maxs out at five objects for most people, but anything less than that and we can quickly tell how many objects there are without even counting thanks to this region of the brain.

In an effort to help surgeons identify and remove brain tumors, scientists have developed a paint that is attracted to specific channels on cancerous cells. The hope is that with this paint, doctors can more accurately remove just the tumor and not any healthy brain tissue. By sparing the surrounding healthy brain tissue, patients will have fewer symptoms after surgery. Read more at NPR’s coverage: Why Painting Tumors Could Make Brain Surgeons Better
This year’s Nobel Prize in Physiology and Medicine has been awarded to three scientists who helped us understand how our cells communicate. The research, conducted over the last 30 years, has broad reaching implications including links to neurodegenerative diseases, cystic fibrosis, muscular dystrophies and some autoimmune disorders..

In an effort to figure out how language helps babies learn, researchers studied infant learning in response to lemur screeches. Amazingly, 3 month old human infants learned in response to lemur shrieks. Although, this effect was gone by 6 months, at which point only human speech helped the babies learn.

As part of ongoing research to determine the causes of migraines, researchers using MRI discovered that the brains of those of us who suffer from migraines have white matter abnormalities that appear similar to mini-strokes. There is also a slightly increased risk for stroke for those who experience migraines with aura (flashing lights before a migraine), making it very important to practice stroke prevention.

The NFL has agreed to pay $765 million dollars to resolve a lawsuit brought by over 4,500 ex-players and their families, accusing the league of concealing the dangers of repeated head trauma. The money will go to players or families of players who sustained cognitive injury as well as to funding scientific research. The league has denied any wrongdoing and insists that safety has always been a top priority, but research has indicated a link between repeated head trauma and development of brain disorders, including chronic traumatic encephalopathy (CTE), depression and Alzheimer’s disease.

The Japanese company Scentee has created an attachment for the iPhone that can spray out scents ranging from flowers to cooked meats. In their commercial, the company makes it seem like smelling food can actually hold off cravings, yet scientists beg to differ. You’ll be able to test it yourself in late November 2013 when Scentee makes its debut in the United States. Read more at NPR’s coverage: A Japanese iPhone Gadget Teases The Tummy With Food Smells

NPR – Don’t Call It A Mind-Meld: Human Brains Connect Via Internet. Using electroencephalography (EEG) and transcranial magnetic stimulation (TMS), researchers were able to have one person’s thoughts control another person’s actions. In this case, the subjects (who were also the researchers) were only playing a video game and pressing a button to fire, but still – very cool!
