Thirty years ago, archaeologists digging at one of England’s earliest medieval villages discovered the remains of 73 worn cooking pots. Used for the last time half a century ago, they still hold tiny remnants of their last meal. Which means they provide fascinating insight into what medieval people actually ate on a day-to-day basis. Chemically
You may not realise it, because we always see the same side of it from Earth, but the Moon is pretty weird. The side we see is very different from the far side, which is always facing away from us, and the contrast between these two sides has been a baffling oddity. Now we have a
Various long-exposure campaigns, like the Hubble eXtreme Deep Field (XDF) shown here, have revealed thousands of galaxies in a volume of the Universe that represents a fraction of a millionth of the sky. But even with all the power of Hubble, and all the magnification of gravitational lensing, there are still galaxies out there beyond
There’s no doubt we have too much plastic in our oceans, and it’s all our fault. But an unexpected source of support might help us to solve this terrible environmental problem: marine microbes that eat plastic, breaking the ubiquitous waste material down. In new research, an international team of scientists studied how microbial communities build
ARCADIA, Calif. — SpaceX filed a bid protest in federal court against the government May 17, but most details about the protest, including the specific award being protested, remain undisclosed. SpaceX filed the complaint with the Court of Federal Claims, but requested that the details of the complaint be kept under seal. Even the specific
If you think your mom is laying it on thick about producing grandchildren, take heart: At least you’re not a male bonobo. Bonobo mothers have been seen performing a variety of behaviors that seem to lend their sons an advantage when it comes to fathering babies, according to a study published Monday in Current Biology
Tiger sharks, aptly named because of their tiger-like stripes on the sides of their body, are arguably one of the most infamous sharks in the world. Known as “garbage cans of the sea” because of the junk that has been found in their stomachs (like chicken wire, TNT, and parts of a suit of armor),
WASHINGTON — EchoStar Corp. on May 20 agreed to sell its waning broadcast satellite services business to Dish Networks for $800 million, reshaping EchoStar as a company whose primary focus is on internet connectivity. The sale includes nine satellites — half of EchoStar’s fleet when counting leased payloads — plus employees who handled satellite operations,
The Solar System might be a soggier place than we previously thought – even in the glacially cold reaches of the Kuiper Belt. There, dwarf planet Pluto could be harbouring liquid oceans under a shell of nitrogen ice. It was thought that the temperature required to maintain a liquid ocean on Pluto was too high
Hey, I wonder if there’s any science around here? Free for commercial use (via Pixabay) For decades the standard route from science to the public has been a follows. Scientist does research. Scientist writes a paper. Sometimes the scientist tells the press office at their university that they wrote a paper. If the press office
Those who watched the full 51-minute version of Jeff Bezos’ May 9 Blue Moon announcement were treated to a tutorial on the work of Dr. Gerard K. O’Neill. In the 1970s Dr. O’Neill popularized the idea of space colonies that rotate in orbit allowing tens of thousands of inhabitants to live comfortable lives in Earth-like
It’s long been known that cannabis plants are indigenous to Central Asia, but a new study provides a fresh focus on where exactly this genus may have first evolved millions of years ago. Documents dating back to the middle ages show humans have been hypothesising about the geographical origins of cannabis for over a thousand
Sound isn’t just something we hear. It’s a formidable physical phenomenon – a wave of pressure that reverberates through the air around us. But the medium sound moves through doesn’t have to be air. Incredibly loud sounds can also travel through water, sometimes even being the result of particularly noisy fish. But if you really want
A new breeding ground for endangered scalloped hammerhead sharks (Sphyrna lewini) has been found in the Galápagos Islands, according to the Ecuadorian government. The area was discovered in the coastal area of Santa Cruz Island during a recent Galápagos National Park Directorate (GNPD) monitoring excursion. According to Eduardo Espinoza, the park ranger who led the
Did you know that there are forests in the Arctic? Lush underwater forests of large brown seaweeds (kelps) are particularly striking in the Arctic, especially in contrast to the land where ice scour (scraping of sea ice against the sea floor) and harsh climates leave the ground barren with little vegetation. Kelp forests have been
WASHINGTON — In order to meet the goal of landing humans on the moon in 2024, NASA needs to get one element of its proposed lunar Gateway on contract in the near future so it will be ready in time. NASA’s latest plans for getting humans back to the surface of the moon involve the
Researchers have pinpointed a previously unknown source of volcanoes in the extreme depths of Earth – in the transition zone between the upper and lower mantle. Until now, we thought we had a handle on the ways in which volcanoes form, welling up from the molten regions in the upper mantle beneath our planet’s crust,

As the world becomes increasingly interconnected and technology-dependent, a new wave of smart applications is changing how we approach everyday activities.

The HAC draft report notes that the decision to not back the $72 million request should not be read as a complete rejection of the idea of establishing a Space Force. WASHINGTON — The House Appropriations Committee says in a draft report says it will not support the Pentagon’s $72.4 million request to establish a
Finally, 130 years after it was established, the kilogram as we know it is about to be retired. But it’s not the end: tomorrow, 20 May 2019, a new definition will be put in place – one that’s far more accurate than anything we’ve had until now. After the shift was unanimously voted in at the
