Electronic structure of a semiconductor device – how it behaves when voltage is applied – visualized for the first time. Insights from the technique will help development of high performance electronics with low power consumption. This will help to to pave the way for two dimensional semiconductors in future electronics
The internet is unique in that it has no central control, administration or authority. It has given everyone with access to it a platform to express their views and exchange ideas with others instantaneously. But in recent years, internet services such as search engines and social media platforms have increasingly been provided by a small number of very large tech firms.
There are many unspoken rules of human interaction, whether that’s whether or not to look them in the eyes, the firmness of the handshake, smiling or words of greeting. Little things like this can lead to big judgments about trustworthiness or social acceptability.
Flying faster than the speed of sound still sounds futuristic for regular people, more than 15 years after the last commercial supersonic flights ended. The planes that made those journeys, the 14 aircraft collectively known as the Concorde, flew from 1976 to 2003. It traveled three times faster than regular passenger aircraft, but the airlines that flew it couldn’t make a profit on its trips.
The ESA is helping a group of students from Zurich test and develop their hopping exploration robot. Called SpaceBok, the robot is designed to operate on low-gravity bodies like the Moon or asteroids. It’s based on the concept of ‘dynamic walking’, something that animals on Earth use.
Many people who are old enough to have experienced the first moon landing will vividly remember what it was like watching Neil Armstrong utter his famous quote: “That’s one small step for a man, one giant leap for mankind.”. Half a century later, the event is still one of the top achievements of humankind. Despite the rapid technological advances since then, astronauts haven’t actually been back to the moon since 1972.
The island of Santorini in the Mediterranean has attracted people for millennia. Today, it feels magical to watch the sun set from cliffs over the deep bay, surrounded by cobalt blue churches and whitewashed houses. This mystical place attracts about 2 million tourists per year, making it one of the top destinations in Greece.
Imagine a world where humans co-existed with beings who, like us, had minds, thoughts, feelings, self-conscious awareness and the capacity to perform purposeful actions – but, unlike us, these beings had artificial mechanical bodies that could be switched on and off.
As driverless cars become more capable and more common, they will change people’s travel habits not only around their own communities but across much larger distances. Our research has revealed just how much people’s travel preferences could shift, and found a new potential challenge to the airline industry.
While the look and feel of our cars has changed in the past 100 years, the way we drive them hasn’t. But fundamental change is coming. In the next decade, not only will the way they’re powered and wired have shifted dramatically, but we won’t be the ones driving them anymore.
By oxidizing methane and converting it to methanol, methanotrophic bacteria (or “methanotrophs”) can pack a one-two punch. Not only are they removing a harmful greenhouse gas from the environment, they are also generating a readily usable, sustainable fuel for automobiles, electricity and more.
As artificial intelligence systems take on more tasks and solve more problems, it’s hard to say which is rising faster: our interest in them or our fear of them. Futurist Ray Kurzweil famously predicted that “By 2029, computers will have emotional intelligence and be convincing as people.”
Whenever I visit the Sahara I am struck by how sunny and hot it is and how clear the sky can be. Aside from a few oases there is little vegetation, and most of the world’s largest desert is covered with rocks, sand and sand dunes. The Saharan sun is powerful enough to provide Earth with significant solar energy.
The parasitic wasp can do something special. The insect is able to puncture rotten wood or a fruit and thus lay eggs in larvae that live in these kinds of places. The wasp uses a long tube for this. But this tube is so long that the animal cannot push it into the material itself. The secret is that this "needle", which consists of three separate parts, can pull itself forward.
Some of the most famous scientific discoveries happened by accident. From Teflon and the microwave oven to penicillin, scientists trying to solve a problem sometimes find unexpected things. This is exactly how we created phosphorene nanoribbons – a material made from one of the universe’s basic building blocks, but that has the potential to revolutionise a wide range of technologies.
In 2011, Microsoft co-founder Paul G. Allen and Scaled Composites founder Burt Rutan announced the creation of Stratolaunch Systems. With the goal of reducing the associated costs of space launches, the company set out to create the world’s largest air-launch-to-orbit system. After many years, these efforts bore fruit with the unveiling of the massive Scaled Composites Model 351 Stratolaunch air carrier in the Summer of 2017.
