Named ZTF J1406+1222, the pair has the shortest orbital period yet identified, and is unique in that it appears to host a third star that orbits around the two inner stars every 10,000 years. |
| Remote programming of cardiac implantable devices is safe for MRI scan, study suggests Posted: 04 May 2022 08:04 AM PDT More than 60 million magnetic resonance imaging (MRI) scans are performed worldwide each year, but imaging for the millions of patients with cardiac implantable electronic devices (CIEDs) such as pacemakers is a logistical challenge, because of concerns with how the magnetic field affects the implants. Now, a newly published study reveals safe and effective reprogramming of these devices is possible, even from a remote location. |
| A new wearable technology -- for plants Posted: 04 May 2022 07:09 AM PDT Plants can't speak up when they are thirsty.

| Urbanization linked to poor ecological knowledge, less environmental action Posted: 04 May 2022 05:26 AM PDT A new study highlights a sharp contrast between urban and suburban ways of thinking about coastal ecosystems. The authors of the study used statistical and cognitive science techniques to analyze data from a survey of 1,400 residents across the U.S. East Coast. Their results showed that surveyed residents of urban centers often held a more simplistic, and less realistic, understanding of coastal ecosystems than residents in suburban areas. The research also uncovered a lower propensity to take pro-environmental actions among urban populations. |

| Image-based mechanical simulations improve accuracy in gauging healing progress of bone fractures Posted: 02 May 2022 06:48 AM PDT When you first break a bone, the body sends out an inflammatory response, and cells begin to form a hematoma around the injured area. Within a week or two, that blood clot is replaced with a soft material called callus that forms a bridge of sorts that holds the fragments together. Over months, the callus hardens into bone, and the healing process is complete. But sometimes, that bridge between the bones fails to form, creating a nonunion. |
