NASA Juno spacecraft discovers Jupiter’s magnetic field changes over time

NASA Juno spacecraft discovers Jupiter’s magnetic field changes over time

NASA has a spacecraft orbiting Jupiter called Juno that has been toiling away for a long time now. One of the things Juno has been doing is investigating the magnetic field of the planet. Juno has discovered that the internal magnetic field of Jupiter changes over time; the phenomenon is called secular variation.

Unchecked climate change may cause 6.5ft ocean rise by 2100

Unchecked climate change may cause 6.5ft ocean rise by 2100

If climate change is allowed to continue at its current rate, the world may face a 6.5ft rise in ocean levels by the year 2100. The warning comes from nearly two dozen ice sheet experts who were quizzed on plausible sea level rise (SLR) based on anticipated ice sheet melting under global temperature increase projections. Such a drastic ocean level increase would be catastrophic for many coastal cities around the world.

FSTAR robot flies or drives with a reconfigurable design

FSTAR robot flies or drives with a reconfigurable design

Prof. David Zarrouk from Ben-Gurion University of the Negev (BGU) has created an interesting robot that is reconfigurable. The robot can fly like a typical quadcopter and then drive on rough terrain if needed. The idea was to create a robot that can squeeze itself into tight spaces using the same motors that it uses for flying; the robot is called FSTAR.

Doggo the robot navigates rough terrain and does backflips

Doggo the robot navigates rough terrain and does backflips

Researchers at Stanford University have developed a new robot that is dog-like and designed to be able to navigate rough terrain and offer lots of agility. The robot is called Doggo, and it can trot, jump, and backflip with no need for treats as a reward. Doggo is designed with reproducibility in mind. Rather than keeping the construction methods and code under wraps, the researchers put it all onto the web freely so users can build their own versions.

Audacious climate change plan appeals to wallets more than ethics

Audacious climate change plan appeals to wallets more than ethics

Increasing carbon dioxide in the atmosphere to improve climate change seems paradoxical, but Stanford researchers argue that new tech and the promise of bottom line profits could coax big industry into getting greener. A new study proposes a more pragmatic approach to greenhouse gases, along with a financial lure to maximize compliance.

Complete Mars 2020 spacecraft revealed for the first time

Complete Mars 2020 spacecraft revealed for the first time

NASA has revealed the spacecraft that the new Mars rover will use to travel to the red planet in 2020, as the US space agency continues to pave the way for an eventual manned mission. Mars 2020 will see a brand new rover set loose on the surface of the planet, complete with a toolkit of all-new instrumentation to do research.

Next optical atomic clock chip is smaller than a coffee bean

Next optical atomic clock chip is smaller than a coffee bean

Most of us take time for granted and presume that seconds are just, well, seconds. For some applications in science and technology, however, being precise down to the millisecond can make a world of difference. For that kind of precision, atomic clocks are the name of the game and the NIST's in-development clock has a beating hart so small that a coffee bean would stand tall beside it.

T-Cell “training” video could help fight Type 1 diabetes

T-Cell “training” video could help fight Type 1 diabetes

Forget outer space or the deep ocean or even the quantum realm. Our bodies are a microcosm of its own, with many parts and processes we still don't completely understand. One of those is our body's own immune system that protects us from diseases. Its most lethal weapon, the T cells, are also unfortunately also the cause of some life-threatening diseases. Doctors are now seeing, for the first time, the T-cells' "safety test" training recorded on video which can hopefully inform them how to properly train these killers.

NASA shares first image of Astrobee ‘Bumble’ robotic assistant on ISS

NASA shares first image of Astrobee ‘Bumble’ robotic assistant on ISS

Last month, a spacecraft arrived at the International Space Station carrying, among other cargo, small cube-shaped robots called Astrobees. The devices are designed to operate in the space lab's unique microgravity environment, offering assistance to the astronauts located on the ISS. In its most recent update on the matter, NASA shared an image of the Astrobee robot 'Bumble' on the ISS alongside some details about how it and its 'Honey' companion are operating.

Milk carton of the future shows exact expiration with QR code

Milk carton of the future shows exact expiration with QR code

Food scientists are developing a milk carton suitable for a future in which most people own a smartphone, Cornell University has announced. The cartons would reduce food waste by helping consumers tell whether their milk (and, presumably, other beverages) are still in good quality and suitable for consumption. In comparison, existing 'Best by' dates are often imprecise.

NASA details Ultima Thule in first profile of Kuiper Belt object

NASA details Ultima Thule in first profile of Kuiper Belt object

NASA has published the first batch of results from the New Horizons' Kuiper Belt object flyby that took place on January 1, 2019. Only about 10-percent of the data from that flyby has been transmitted back to researchers on Earth, but the findings have been shared in a study published on May 17. According to the space agency, the object -- which is nicknamed Ultima Thule -- is 'far more complex than expected.'

You may be genetically hardwired to love dogs

You may be genetically hardwired to love dogs

Genetics may explain why some people are self-avowed dog lovers, according to a new study. The research found that dog ownership has a heritable component, meaning a person's genetic makeup may heavily influence whether they choose to own a dog. Uppsala University researchers behind the study describe the genetic influence as both 'significant' and surprising.
