While the web of dark matter (purple) might seem to determine cosmic structure formation on its own, the feedback from normal matter (red) can severely impact galactic scales. Both dark matter and normal matter, in the right ratios, are required to explain the Universe as we observe it. Neutrinos are ubiquitous, but standard, light neutrinos
Let’s apply and torque and have fun!Michael Rivera (Creative Commons v4.0) Let’s talk about nobody’s favorite physics concept: torque. Torque is pretty magical, honestly, and if you’re not already familiar with it then you absolutely should be. Chances are you’ve applied the principle of torque hundreds, if not thousands, of times in your life. You

With Brexit quickly approaching, the British government has been negotiating trade deals with countries around the world with the aim of transitioning its economy away from European markets. However, initial conversations with the Trump administration have forced the United Kingdom to consider how much it is willing to sacrifice in order to make a deal.
SEOUL (Reuters) – Perhaps none of the communist legacies shared by Vietnam and North Korea highlighted during Kim Jong Un’s “goodwill visit” to Hanoi is stranger than the embalmed leaders on display in their capital cities, and the secretive team of Russian technicians that keeps the aging bodies looking ageless.

Beyond the argument that education should be designed to create a well-rounded citizen with an appreciation for a wide range of knowledge, there have been dozens of large-scale studies showing that an integrated curriculum of the sciences, humanities, and arts helps students excel in all areas of K-12 learning. Of course, the sciences aren’t going

Our deepest galaxy surveys can reveal objects tens of billions of light years away, but there are more galaxies within the observable Universe we still have yet to reveal. Most excitingly, there are parts of the Universe that are not yet visible today that will someday become observable to us.Sloan Digital Sky Survey (SDSS) Even
Some 40% of firms across Europe classified as being “AI start-ups” showed no evidence that they used AI, according to new research from venture firm MMC.

To practice cervical cancer biopsies, medical students might use models with raw meat. Yes, meat, such as beef tongue. This is messy and easily contaminated, and it’s especially impractical for warm and remote settings like some Malawian towns. A group of students from the Malawi Polytechnic and Rice University has designed gel-based models of the

Skepticism is a powerful tool. One that can and should be used in a variety of situations. And at first glance a properly skeptical attitude seems so easy to adopt: just, like, try not to believe everything instantly. Of course, like most things in life, it’s easier said than done. Skepticism must become a habit.
A scenic view of Mount Shasta in Northeast California (Carol M. Highsmith/Buyenlarge/Getty Images) California isn’t exactly known for its volcanic activity. In the minds of most, it’s a place where tectonic forces battle it out, gearing parts of the state up for a dangerous and perhaps catastrophic earthquake. Things, however, aren’t quite so uniform. The United
The state of Florida (USA) has formally announced new land-based recreational shark fishing rules, approved via a unanimous vote by the Florida Fish and Wildlife Conservation Commission. This came after seven years of hard work by numerous people, including Dr. David Shiffman who is a marine conservation biologist at Simon Fraser University, and worked on land based shark
The winter of 2019 in the United States has lived up to its name. There have been record cold temperatures, Polar Vortex intrusions, strange rotating ice discs, and the requisite snowstorms. This week I noticed viral videos getting around of massive chunks of ice invading the shores of the Great Lakes region. My colleague Professor
