Intelligent alien life hunters pick up 15 high-energy bursts far across the universe

Intelligent alien life hunters pick up 15 high-energy bursts far across the universe

Instruments at the Green Bank Telescope in West Virginia identified 15 mysterious high-energy radio signals which are still unattributed. Brief but intense radio pulses have been recorded emanating from FRB 121102, a dwarf galaxy some 3 billion years away. Scientists working at Breakthrough Listen – a $100 million effort to search for alien signals – […]

How old is the oldest tree?

How old is the oldest tree?

Just like Treebeard the Ent claims to be the oldest creature in Middle Earth, trees are among the oldest living beings on real Earth. The oldest tree depends on what you count as a “tree” but ranges from 5,000 to 80,000 years. Now that’s a long time! Trees have been around for such a long […]

We’re made of stardust, but heavier elements are made of black-hole-and-neutron-star dust

We’re made of stardust, but heavier elements are made of black-hole-and-neutron-star dust

Heavier chemical elements could be the love child of two very spectacular and exotic lovers – neutron stars and tiny black holes. “Papa?” Image via Digitaltrends. We are, as Carl Sagan once put it, “made of star stuff.” Considering that what we call a star is actually a ginormous reactor mashing hydrogen and helium atoms […]

Jupiter now officially has 69 moons. There are likely more to be confirmed

Credit: NASA. It’s amazing how astronomers are still discussing the possibility of finding a new planet in the solar system in 2017. Compared to that, finding new moons shouldn’t be all that surprising, especially around Jupiter which is some 630 million miles away from Earth. In fact, the environment around Jupiter, a planet 317 times […]

Organic food requires 40% more land than conventional farming for the same carbon footprint

Organic food requires 40% more land than conventional farming for the same carbon footprint

Credit: Pixabay. Many people are rightfully disappointed by how most conventional farmers grow food, which has springboarded a massive movement around ‘organic food’. This is supposedly food derived from crops and meat that’s been grown in a healthier and simpler manner, akin to how it was done in the good ol’ days before intensive agriculture. […]

Ancient climate change turned whales into Earth’s largest ever organisms, study reports

Ancient climate change turned whales into Earth’s largest ever organisms, study reports

Ancient shifts in climate may have powered the baleen whale’s growth to such “ginormous” sizes, a new paper reports. “Ginormous” seems rather fitting. With some individuals growing to be the length of an average basketball court and weighing upwards of 200,000 kilograms (441,000 pounds), the blue whale is big fry indeed – in fact, they’re […]

Pet dogs help kids feel less stressed, new study confirms

A new study confirmed what I’d assume most people already knew: a pet dog provides valuable moral support for a kid. Image credits: poppofaticus. Pet ownership affects children in more ways than one, generally with an overwhelmingly positive impact. It starts with basic, physical health – having a dog tends to make you healthier because […]
