Camera aboard NASA spacecraft confirms asteroid phenomenon
Posted by Genevieve Klien in category: space
WASHINGTON – A U.S. Naval Research Laboratory-built camera mounted on the NASA Parker Solar Probe revealed an asteroid dust trail that has eluded astronomers for decades.
Karl Battams, a computational scientist in NRL’s Space Science Division, discussed the results from the camera called Wide-Field Imager for Solar Probe (WISPR) on Dec. 11 during a NASA press conference.
WISPR enabled researchers to identify the dust cloud trailing the orbit of the asteroid 3200 Phaethon.

The Battle Is For The Customer Interface
Posted by Amnon H. Eden in categories: internet, mobile phones
The power shift continues.
Uber, the world’s largest taxi company, owns no vehicles. Facebook, the world’s most popular media owner, creates no content. Alibaba, the most valuable retailer, has no inventory. And Airbnb, the world’s largest accommodation provider, owns no real estate. Something interesting is happening.
Since the Industrial Revolution, the world has developed complex supply chains, from designers to manufacturers, from distributors to importers, wholesalers and retailers, it’s what allowed billions of products to be made, shipped, bought and enjoyed in all corners of the world. In recent times the power of the Internet, especially the mobile phone, has unleashed a movement that’s rapidly destroying these layers and moving power to new places.

The Rise Of Open-Source Software
Posted by Derick Lee in categories: business, entertainment
Open-source software powers nearly all the world’s major companies. This software is freely available, and is developed collaboratively, maintained by a broad network that includes everyone from unpaid volunteers to employees at competing tech companies. Here’s how giving away software for free has proven to be a viable business model.

Bone bandage soaks up pro-healing biochemical to accelerate repair
Posted by Saúl Morales Rodriguéz in category: biotech/medical
Researchers at Duke University have engineered a bandage that captures and holds a pro-healing molecule at the site of a bone break to accelerate and improve the natural healing process.
In a proof-of-principle study with mice, the bandage helped to accelerate callus formation and vascularization to achieve better bone repair by three weeks.
The research points toward a general method for improving bone repair after damage that could be applied to medical products such as biodegradable bandages, implant coatings or bone grafts for critical defects.

New methods could help researchers watch neurons compute
Posted by Saúl Morales Rodriguéz in categories: computing, neuroscience
Since the 1950s at least, researchers have speculated that the brain is a kind of computer in which neurons make up complex circuits that perform untold numbers of calculations every second. Decades later, neuroscientists know that these brain circuits exist, yet technical limitations have kept most details of their computations out of reach.
Now, neuroscientists reported December 12 in Cell, they may finally be able to reveal what circuits deep in the brain are up to, thanks in large part to a molecule that lights up brighter than ever before in response to subtle electrical changes that neurons use to perform their compuations.
Currently, one of the best ways to track neurons’ electrical activity is with molecules that light up in the presence of calcium ions, a proxy for a neuron spike, the moment when one neuron passes an electrical signal to another. But calcium flows too slowly to catch all the details of a neuron spike, and it doesn’t respond at all to the subtle electrical changes that lead up to a spike. (One alternative is to implant electrodes, but those implants ultimately damage neurons, and it isn’t practical to place electrodes in more than a handful of neurons at once in living animals.)
