Single DNA molecule used to create smallest diode in all the land

Single DNA molecule used to create smallest diode in all the land

Researchers have created the world's smallest diode and they did it using a single molecule of DNA. The creation was devised by researchers from the University of Georgia and Ben-Gurion University in Israel. The creation has shown for the first time that nanoscale electronic components can be made using a single DNA molecule. The breakthrough is seen as an advance that could aid in the search for replacement in silicon chips.

Pluto’s heart may be heavy enough to have tipped it over

Pluto’s heart may be heavy enough to have tipped it over

One of the coolest things about Pluto that was shown in the images sent back by the New Horizons probe is the heart-shaped area on the surface dubbed Tombaugh Regio. Scientists have been researching the data gathered by New Horizons and the study is now suggesting that the heart-shaped area might be heavy enough to have tipped the dwarf planet on its side. The west side of the heart called Sputnik Planum with its smooth surface is through to be what remains of a large crater that filled with nitrogen ice.

Reverse photosynthesis breaks down plants for clean biofuels

Reverse photosynthesis breaks down plants for clean biofuels

Researchers have discovered what is being called a major milestone in the world of biofuels: reverse photosynthesis, a process that uses the sun’s rays to break down plants rather than build them up. Such a discovery has two major benefits over current methods used to break down plant biomass — the process itself is faster, and because the sun is being used, the process produces far less pollution, potentially providing a solution to one of the petrochemical industry’s biggest problems.

Blue Origin shares video of important third landing

Blue Origin shares video of important third landing

Over the weekend, Blue Origin, the space agency backed by Amazon's Jeff Bezos, made yet another successful landing of the New Shepard rocket. In fact, this is the third time that very same rocket was launched and landed, first in November and then in January. The company has finally shared the edited video footage of that launch. And while the video seemed almost ordinary and normal, which is probably part of the message, it almost belies the significance of Blue Origin's achievement in the fields of space science and space travel.

Blue Origin reusable rocket completes third launch and landing

Blue Origin reusable rocket completes third launch and landing

Jeff Bezos and his private spaceflight agency Blue Origin are now three-for-three in successfully launching and landing their reusable rocket into space. Their New Shepard rocket — the same one that was launched and landed in November and again in January — repeated the feat once again on Saturday morning, lifting off at 11:18 AM Eastern. Bezos tweeted updates as the event took place, noting that the landing was "perfect."

NASA sending fungi into space to study drug development

NASA sending fungi into space to study drug development

A team of researchers from NASA and the University of Southern California will be the first in the world send fungi into space with the goal of developing medical drugs. The fungi, which are known to produce molecules called secondary metabolites, will hitch a ride to the International Space Station aboard a SpaceX rocket scheduled to launch on April 8th. Secondary metabolites can be used to create beneficial medicine for humans, such as the antibiotic penicillin.

Blue Origin to launch its reusable rocket a third time

Blue Origin to launch its reusable rocket a third time

Blue Origin, the private space agency owned by Amazon's Jeff Bezos, has revealed that for a third time it will be launching its reusable rocket later today, followed of course by another successful landing attempt. "Working to fly again tomorrow. Same vehicle. Third time. #LaunchLandRepeat," Bezos tweeted on Friday, indicating that they will be using the same New Shepard rocket that has already been launched and made a soft landing on two separate occasions.

Possible North America Viking settlement spotted from space

Possible North America Viking settlement spotted from space

A second Viking settlement may have been found in North America, and it’ll be detailed in an upcoming NOVA documentary called “Vikings Unearthed.” The discovery was made from space, in that archaeologists spotted evidence of the settlement in photos taken by a satellite. The discovery was made some time last summer, and though the precise location of the settlement hasn’t been revealed to the public, it is somewhere in the southern region of Newfoundland.

Sun-like star has a planet developing around it right now

Sun-like star has a planet developing around it right now

Scientists the world over are always out for new insights to exactly how planets form around stars early in their existence. Recently scientists snapped images of a very young planet that is currently forming around its parent star. That parent star is called TW Hydrae and it has a planet forming disc orbiting around it. One curious planet is forming around the star at roughly the same distance that Earth is from the sun.

Image shows what scientists describe as almost a spider

Image shows what scientists describe as almost a spider

The image you see here is a computer tomography picture of an arachnid that is 305 million years old. It might look like a spider, but it isn't quite a spider according to scientists. The ancient arachnid has scientists aflutter because it is believed to show the stepwise evolution of arachnids into spiders. The only thing this fossil lacks that sets it apart from a spider is the spinnerets spiders use to turn silk into webs.

NASA’s helping track deer birth rates from space

NASA’s helping track deer birth rates from space

NASA is using its satellites to help researchers track deer births from space. This is made possible by tracking vegetation across the nation using satellite imagery. Mule deer, the variety cited by NASA, are in need of ample amounts of vegetation during the late stages of pregnancy and for a while after giving birth -- knowing that, and by using NASA's satellite data, researchers have been able to figure out when fawning season will start.

Chinese AI engineers want to challenge Google’s AlphaGo bot

Chinese AI engineers want to challenge Google’s AlphaGo bot

Earlier this month, headlines were made around the world when Google's artificial intelligence, dubbed AlphaGo, was able to beat the current world champion in four out of five matches of the ancient board game Go. Now the bot may have to face an opponent of its own type: a group of Chinese computer engineers have announced that they plan to challenge Google, pitting AlphaGo against their own AI program.
