Morphospecies theory says t-rex was king carnivore at all stages of life

Morphospecies theory says t-rex was king carnivore at all stages of life

A study released this week shows how the tyrannosaurus consumed different resources at multiple stages of growth. Modern meat-eating mammals can easily be arranged in a chart showing average adult size - each of these animals have a unique effect on their own ecosystem. Given the average size of adult dinosaurs, there appeared to be a massive gap in the middle of the chart from smallest to largest.

People who like cold weather may have a useful genetic mutation

People who like cold weather may have a useful genetic mutation

Are you one of those people who wear shorts in the dead of winter, goes swimming when everyone else is still wearing jackets, and who finds they can handle winter camping more comfortably than their friends? If so, you may be one of the many people who has a genetic mutation linked to increased cold resilience, a benefit in cold climates, but one that may come with a sacrifice in sports performance.

Caltech seismologists use underwater cables to detect earthquakes

Caltech seismologists use underwater cables to detect earthquakes

Seismologists at Caltech have worked with optics experts from Google to develop a new method to detect earthquakes in the ocean. Together, the team developed a method that allows the use of existing underwater telecommunications cables to detect earthquakes. They believe the new technique could lead to improved earthquake and tsunami warnings around the world.

Researchers create a material that could change soft robotics

Researchers create a material that could change soft robotics

Scientists often look to the natural world for inspiration and ideas when creating synthetic materials. Plants and animals can rapidly respond to changes in the environment. An example is the way a Venus flytrap can close quickly when touched by an insect. Researchers have printed liquid metal circuits onto a single piece of soft polymer to create an intelligent material that can curl under pressure or mechanical strain and expand when stretched.

UT researchers definitively link asteroid impact with the demise of the dinosaurs

UT researchers definitively link asteroid impact with the demise of the dinosaurs

Researchers from the University of Texas at Austin say they believe they have definitively closed the case of what killed off the dinosaurs. The team definitively linked the extinction of the dinosaurs to an asteroid that impacted the earth 66 million years ago. The link came when the team found a key piece of evidence in the form of asteroid dust inside the Chicxulub Crater in the Yucatán Peninsula in Mexico.

Researchers discover large galaxies strip star-making gas from nearby smaller galaxies

Researchers discover large galaxies strip star-making gas from nearby smaller galaxies

Astronomers published new research this week, discovering that small satellite galaxies contain less molecular gas in their centers. The team says that large galaxies are known to strip away gas occupying the space between the stars of smaller satellite galaxies. They now know that the larger galaxies can strip away molecular gas at the center of the smaller galaxies, which is the type of gas the smaller galaxies that need to create new stars.

Comet-like Centaur spotted by Hubble near Jupiter’s Trojans

Comet-like Centaur spotted by Hubble near Jupiter’s Trojans

The NASA Hubble Space Telescope has spied a comet-like object known as a Centaur that has settled near a group of captured ancient asteroids called Trojans orbiting alongside Jupiter. NASA says this is the first time a comet-like object has been spotted near the ancient Trojan population. The Centaur name classifies icy bodies in the space between Jupiter and Neptune that become active for the first time when heated as they approach the sun.

Blue Origin delays New Glenn after missing out on Pentagon contracts

Blue Origin delays New Glenn after missing out on Pentagon contracts

After losing out on a Space Force contract, private space company Blue Origin has announced that its New Glenn maiden flight will be bumped to the fourth quarter of 2022. The company says that it hopes it will be able to launch National Security Space Launch (NSSL) payloads in the future in addition to civil contracts, among other things.

NASA guided tour of Mars will tap Perseverance’s most flexible camera

NASA guided tour of Mars will tap Perseverance’s most flexible camera

NASA is preparing a must-see video tour of Mars today, tapping Perseverance's high-tech Mastcam-Z robotic eyes to give a new glimpse of the red planet. It's an opportunity not only to see Mars in full 360-degrees, but also to get a guided view of what the freshly-landed rover can see and why scientists are eager to explore it.

This growing album of Perseverance Mars photos is space geek treasure

NASA's Perseverance rover may not have even moved from its landing spot on Mars in the past week, but that doesn't mean there aren't already thousands of images being shared from the red planet. The latest science-lab-on-wheels successfully touched down on Martian soil last Thursday, February 18, and has been steadily beaming back content to the Jet Propulsion Lab ever since.

Incredible picture of Venus taken by the Parker Solar Probe

Incredible picture of Venus taken by the Parker Solar Probe

As its name implies, NASA's Parker Solar Probe is meant to study the Sun. However, on its way to the Sun, Parker flew past Venus. It took the opportunity to capture some impressive views of the planet during its close flyby in July 2020. While the probe was meant to study the sun, Venus was critical to the mission as the spacecraft will whip around the planet to get gravity assists allowing it to fly closer and closer to the sun to complete its primary mission.

Ancient Egyptian painting shows an extinct goose

Ancient Egyptian painting shows an extinct goose

Researchers from the University of Queensland have examined a 4600-year-old Egyptian painting. During the examination, a rendering of a speckled goose stood out. Scientist Dr. Anthony Romilio noticed a strange and beautiful bird, unlike modern red-breasted geese that had distinct and bold colors and patterns on its face, body, breast, wings, and legs. The painting is called "Medium Geese" and was discovered in the late 1800s.
