In people with Alzheimer’s disease, a new investigational drug can dramatically reduce the amount of amyloid beta plaque, the tangled clumps of proteins that form in the brains of Alzheimer’s patients, according to a new early study of the drug.

The drug works by spurring the immune system to recognize and clear the plaques.

“We believe that’s a hint of efficacy,” study co-author Dr. Alfred Sandrock, a neurologist and an executive vice president at Biogen, said during a news briefing. “We believe that needs to be confirmed with further studies.” Biogen is the Cambridge, Massachusetts, company that funded the trial and applied to patent the drug.

A new technique uses the curious physical laws of the nano-scale itself to “program” nanobots. Welcome to the future of nanotechnology.

Nanorobotics has long been touted as one of the most promising “miracle technologies” of the future. But one of the fundamental problems with such extreme miniaturization is how to “program” nanobots—after all, you can’t very well shrink computer circuitry to fit within nanometer-scale technology.

In a study published in Nature Medicine, researchers report that they have successfully coaxed stem cell-derived neurons to regenerate lost tissue in damaged corticospinal tracts of rats.

Stem cells are an amazing part of medical research. Because of their ability to become virtually any cell in the human body, they could hold the cure for many varied and grave diseases—from bones, to sight, to memory and thinking, stem cells could help us correct a host of conditions.

In fact, it seems that stem cells might be the key to repairing spinal cord injuries.

There is a stark contrast between the cover stories in current issue of Boys’ Life –vs- Girls’ Life. [see it here]. The Boys cover effectively urges males to learn, build, think and question assumptions. But, the Girls cover wonders “Oh My! What will you do with your hair and nails today!

Although I am a feminist—and readily jarred by the juxtaposition of contrary messages—I am giving editors at Girls’ Life a ‘get out of jail’ pass this time. It may not be the sexism that it seems.

Jennifer Wright (@JenAshleyWright) kicked up a firestorm last week, when she tweeted a photo of two side-by-side magazines on a newsstand. The contrast between cover features of Boy’s Life –vs- Girl’s Life is startling. With characteristic sarcastic wit, she tweeted:

“Why are you feminists always complaining?
We treat boys and girls exactly the same.”

For those who are reading without the above image, the current issue of these magazines calls out to readers like this:

  • Boys: Would you like to build and fly the next generation of jet fighters?
  • Girls: What on Earth can you do with your hair and nails this weekend?

Boy'sLife-vs-Girl'sLife

The difference between these covers suggests that the respective magazine editors are pushing 19th century aspirations onto the next generation of 21st century women. It’s a reminder of lingering differences in the way we perceive the sexes. But does this contrast present a fair and balanced comparison?

Certainly, there is work to do—but, the stark difference between these magazine covers may not point to a societal ill in the way that seems to jump off the screen.

Bloomberg Businessweek alleges that Page has invested more than $100 million of his own personal funds into a flying car company since they started in 2010 and is currently funding another flying car startup.

You know how, when you’re stuck in traffic, you wish that you could pull a secret lever in your car that would make it shoot up in the air, fly you out of the congested street, and quickly whisk you to your meeting—where you are, of course, a corporate (and punctual) hero?

Well, it seems Google cofounder Larry Page may have been thinking the same thing. Bloomberg Businessweek claims that Page secretly owns a startup named Zee. Aero, a company that has been so evasive that employees were allegedly given cards with instructions on how to deflect reporters.

Stanford University School of Medicine scientists have identified a brain circuit that’s indispensable to the sleep-wake cycle. This same circuit is also a key component of the reward system, an archipelago of interconnected brain clusters crucial to promoting behavior necessary for animals, including humans, to survive and reproduce.

It makes intuitive sense that the reward system, which motivates goal-directed behaviors such as fleeing from predators or looking for food, and our sleep-wake cycle would coordinate with one another at some point. You can’t seek food in your sleep, unless you’re an adept sleepwalker. Conversely, getting out of bed is a lot easier when you’re excited about the day ahead of you.

But until this study, no precise anatomical location for this integration of the ’s reward and arousal systems has been pinpointed, said Luis de Lecea, PhD, professor of psychiatry and behavioral sciences.
