MIT creates a new mathematical model to predict the stability of a knot

Humans have known for generations that some knots are stronger than others. This is apparent in sailing, where different types of knots are used for different needs. What exactly makes one type of knot more stable than others hasn't been well known, until now. MIT mathematicians and engineers have developed a mathematical model that predicts how stable a knot is.

Stanford scientists create a miniature particle accelerator-on-a-chip

There are particle accelerators scattered around the world that are used by scientists and researchers to study the atomic and molecular structures of inorganic and biological materials. The typical particle accelerator is a massive device. The accelerator that Stanford University has is nearly 2 miles long and can accelerate electrons to nearly the speed of light.

Water is common on exoplanets, but it’s not as plentiful as expected

Water is common on exoplanets, but it’s not as plentiful as expected

Scientists have discovered something strange about the exoplanets that have been discovered and studied so far. Water, which is essential for life as we know it, is said to be common, but unexpectedly scarce on exoplanets. What scientists have found is that many exoplanets have water, but there is less water on the distant worlds than expected.

Details on the demise of the moon’s magnetic field announced

Details on the demise of the moon’s magnetic field announced

If we took a compass to the moon today, it wouldn't work because the moon has no magnetic field. That wasn't always the case. Scientists at MIT have pinned down the timing of the demise of the lunar dynamo. Scientists say that at one point in the lifecycle of the moon, billions of years ago, it had a magnetic field that was likely stronger than the field that the Earth has today.

Laser-ranging telescopes use algorithms to detect space junk

Laser-ranging telescopes use algorithms to detect space junk

Researchers in China have improved the accuracy of detecting space junk in orbit around the earth. The goal of the project is to allow more effective plotting of safe routes for spacecraft maneuvers. The researchers say that after more than 50 years in space, there is all sorts of debris in orbit that spacecraft need to avoid for safety.

NASA shares frozen moonrise image snapped from space

NASA shares frozen moonrise image snapped from space

Shortly before Christmas, an image was captured from the International Space Station that shows the moon over a frozen winter landscape, offering a unique and somewhat stunning frosty perspective of the celestial body. The image was captured using a Nikon D5 digital camera using a 50mm lens by a member of the Expedition 61 crew.

SpaceX Crew Dragon animation reveals the ISS round trip in store

SpaceX Crew Dragon animation reveals the ISS round trip in store

SpaceX's Crew Dragon capsule has had something of a rocky year, but assuming things go to plan from here on out, we should see it begin to do crewed test flights early next year. Today, SpaceX gave us a taste of what's ahead by releasing a new, three-minute long animation that details a round trip for the Crew Dragon capsule, from lift-off here on Earth to splash down in the ocean.

HabEx mission wants to search for Earth-like exoplanets

HabEx mission wants to search for Earth-like exoplanets

A new space mission called Habitable Exoplanet Observatory or HabEx wants to use a new space telescope to search for habitable Earth-like exoplanets. The mission would use a telescope with a mirror larger than Hubble's and would use origami techniques to utilize an external starshade to block the light from target stars.

Astronaut Christina Koch breaks record for longest female space flight

Astronaut Christina Koch breaks record for longest female space flight

NASA took the time to brag on one of its astronauts not long ago for setting a record for space flight duration. NASA Astronaut Christina Koch has set a record for the longest space flight by a woman after spending 288 days in orbit. That eclipses the record set by former station commander Peggy Whitson.

Scientists are developing the perfect foamy beer head

Scientists are developing the perfect foamy beer head

Researchers with the University of Manchester are paving the way for the perfect foamy beer head, one that will last all the way to the bottom of the glass. At the heart of the research is what makes foams last a long time and how to tweak this for a desirable outcome. In addition to cases in which the foam's longevity could be extended, the same technology could reduce foaming in cases where it is undesirable, such as in laundry detergent.

Cotton candy super-puff worlds found in Kepler 51 star system

Cotton candy super-puff worlds found in Kepler 51 star system

Fluff surrounds the solid interiors of each of the three planets in the Kepler 51 star system. Each of these planets was discovered to have masses "only a few times larger than Earth's" with radii larger than Neptune. Because of these extreme variables, all three studied Kepler 51 planets are now part of a relatively new class of planets called super-puffs!

Researchers show parenting is 40 million years older than previously thought

Researchers show parenting is 40 million years older than previously thought

The creature called Dendromaia was discovered with a younger Dendromaia wrapped around it in fossil form. The fossil pair were dated to approximately 300-MILLION-years-old, making this the new eldest-known example of "parental care" in an animal on our planet Earth. Per research on this find, this puts parental care in animals approximately 40 million years BEFORE the otherwise eldest proof of this characteristic. This is now the eldest-known caring parent ever found.
