Immune and Nerve Cells Work Together to Fight Gut Infections
Posted by Shailesh Prasad in categories: biotech/medical, neuroscience
Nerve cells in the gut play a crucial role in the bodyâs ability to marshal an immune response to infection, according to a new study from Weill Cornell Medicine scientists.
The study, published in Nature, shows that the immune system and nervous system have co-evolved to respond to infectious threats. This means that scientists looking for ways to treat diseases like inflammatory bowel disease or asthma that involve an excessive immune system response may also have to address the nervous systemâs role.
âThe immune system and neuronal system donât act independently,â said senior author Dr. David Artis, director of the Jill Roberts Institute for Research in Inflammatory Bowel Disease and the Michael Kors Professor of Immunology at Weill Cornell Medicine. âThey are working together.â

A Tunisian Energy Company Wants to Pipe Electricity from the Sahara to Europe
Posted by Shailesh Prasad in categories: government, solar power, sustainability
The company TuNur aims to produce solar energy cheaply in the Sahara desert and distribute it to Europe. However, there are lingering questions about whether the company behind the project can actually pull it off.
Energy company TuNur is seeking approval from the Tunisian government for a 4.5GW solar park situated in the Sahara desert. If itâs given the green light, the project would distribute electricity to Malta, Italy, and France via submarine cables.

California-based SSL, formerly known as Space Systems Loral, says itâll receive continued funding from NASA for an on-orbit satellite assembly program known as Dragonfly. SSL and its partners, including Bothell, Wash.-based Tethers Unlimited, recently completed a successful ground demonstration of the Dragonfly system, which is designed to assemble pieces of space hardware in orbit robotically. The next step is to move forward with a detailed design for a semi-autonomous assembly system that could be sent into space sometime in the 2020s. Check out this 11-second video clip about the Dragonflyâs ground test:

Nanotechnology experts create first terahertz-speed polarization optical switch
Posted by SaĂșl Morales RodriguĂ©z in categories: electronics, nanotechnology
A Sandia National Laboratories-led team has for the first time used optics rather than electronics to switch a nanometer-thick thin film device from completely dark to completely transparent, or light, at a speed of trillionths of a second.
The team led by principal investigator Igal Brener published a Nature Photonics paper this spring with collaborators at North Carolina State University. The paper describes work on optical information processing, such as switching or light polarization control using light as the control beam, at terahertz speeds, a rate much faster than what is achievable today by electronic means, and a smaller overall device size than other all-optical switching technologies.
Electrons spinning around inside devices like those used in telecommunications equipment have a speed limit due to a slow charging rate and poor heat dissipation, so if significantly faster operation is the goal, electrons might have to give way to photons.
