Astronomers observe up to three newborn planets evolving from a disk of gas and dust particles circling a distant Sun-like star.

 

While 1,900 planets have been discovered outside our solar system, these are the first to be seen that are still forming. The discovery, reported in the journal Nature, has provided scientists with direct evidence of how gas and dust particles coalesce to create planets.

To better understand how educating individuals can make a global difference, consider what we should stop doing, what we should start doing, and what we should continue doing.

What Should We Stop Doing?Stop teaching as if we have the answers.Stop rushing.Stop talking.What Should We Start Doing?Start looking for problems to solve, actions to take, and beauty to create.Start seeking out authentic, high-stakes audiences for student work.

International firm Penda Architecture and Design has designed a meadow with sunken pathways for China’s International Garden Expo 2015.

As part of China’s International Garden Expo, Beijing– and Vienna–based firm Penda Architecture and Design has designed a temporary meadow, named “Where the River Runs,” sited for Wuhan, China. The installation, which contains sunken pathways and hidden meeting places, allows visitors to walk along a winding trail through the meadow, mimicking an imaginary river. With this installation, the architects hope to highlight that clean water is not an endless resource. 

The pathways lead towards a central, sheltered plaza below the landscaped surface. As visitors wind towards the plaza, they are invited to sprinkle seeds over the grass to encourage the growth of new plants and flowers…

A team of researchers with Ulsan National Institute of Science and Technology and Dong-A University, both in South Korea, has developed an artificial skin that can detect both pressure and heat with a high degree of sensitivity, at the same time. In their paper published in the journal Science Advances, the team describes how they created the skin, what they found in testing it and the other types of things it can sense.

Many scientists around the world are working to develop artificial skin, both to benefit robots and human beings who have lost skin sensation or limbs. Such efforts have led to a wide variety of artificial skin types, but until now, none of them have been able to sense both pressure and heat to a high degree, at the same time.


The new artificial skin is a sandwich of materials; at the top there is a flexible surface meant to mimic the human fingerprint (it can sense texture), beneath that sit sensors sandwiched between graphene sheets. The sensors are domed shaped and compress to different degrees when the skin is exposed to different amount of pressure. The compression also causes a small electrical charge to move through the skin, as does heat or sound, which is also transmitted to sensors—the more pressure, heat or sound exerted, the more charge there is—using a computer to measure the charge allows for measuring the degree of sensation “felt.” The ability to sense sound, the team notes, was a bit of a surprise—additional testing showed that the artificial skin was actually better at picking up sound than an iPhone microphone.
