Injectable foam stops internal bleeding on the battlefield

The polyurethane foam begins as two liquids stored separately and injected together into the abdominal cavity.

Despite the best efforts of military first responders to stabilize abdominal wounds sustained on the battlefield, they have few options when it comes to stopping internal bleeding caused by gunshots or explosive fragments.  DARPA is studying a new type of injectable foam that molds to organs and slows hemorrhaging. This could provide field medics with a way to buy more time for soldiers en route to medical treatment facilities.

California To Be First U.S. State to Ban Styrofoam Containers

styrofoam-ban-california

 Styrofoam takes forever to biodegrade, it clogs up waterways, and wildlife mistake it for food and ingest it.

The state Senate in California just voted to ban the sale of Styrofoam containers.  Restaurants and shops would be banned from distributing food in foam containers.  Californian’s takeout and sodas will have to be sold in more sustainable, or ideally, reusable containers. Some 50 municipalities in the state have already enacted such bans. If the measure passes the state Assembly, it will make California the first in the nation to ban styrofoam.

Robotic System That Will Operate On A Beating Heart

Robotic System That Will Operate On A Beating Heart 

This device lets surgeons attach small anchors to tissue inside a beating heart by compensating for the heart’s movement. 

Fixing the heart is hard. Certain procedures have to be performed on a stationary organ, so the heart is stopped and the patient put on a cardiopulmonary bypass machine. But stopping the heart increases the risk of brain damage. Now researchers at Harvard University and Children’s Hospital Boston are testing a robotic system that could help surgeons perform a common valve repair while the heart beats on. The system uses 3-D ultrasound images to predict and compensate for the motion of the heart so that the surgeon can work on a patient’s mitral valve as it moves.

Sound Wave Chair

Sound Wave Chair 

 Sound Chair

Although this chair looks like it’s made from LEGO, designer Matthew Plummer Fernandez actually used a much more geeky material in building it: sound waves. The Sound/Chair has contours that precisely match sound waves mapped on a 3D graph of volume (height), frequency (depth), and time (width).  We love the purple color, too (but then again, we would).
