Watch out space, there’s a new commercial cargo carrier entering the race.

Sierra Nevada Corporation (SNC) has been given the go ahead from NASA to begin full-scale production of it’s “Dream Chaser” commercial space cargo plane. Scheduled to make its first mission in 2020, the company announced on December 18 that it had cleared the last milestone in its Commercial Resupply Services 2 contract. Now the company is able to move ahead with the full-scale production of the carrier which will be used to deliver cargo to the International Space Station (ISS).

It’s not difficult to verify whether a new piece of information is accurate; however, most people don’t take that step before sharing it on social media, regardless of age, social class or gender, a new Ohio University study has found.

A new study conducted by Ohio University professor Dr. M. Laeeq Khan found that several factors can be used to predict someone’s ability to detect misinformation, otherwise known as “fake news,” on social media. Additionally, the study found that, by looking at certain factors, it is also possible to predict if someone is likely to share misinformation based on the same factors.

The study, titled “Recognise misinformation and verify before sharing: a reasoned action and information literacy perspective,” was published in the journal Behaviour and Information Technology.

This is an invention that might possibly modify the civilization as we know it: A compact fusion reactor presented by Skunk Works, the stealth experimental technology section of Lockheed Martin. It’s about the size of a jet engine and it can power airplanes, most likely spaceships, and cities. Skunk Works state that it will be operational in 10 years.

Boston University researchers, Xin Zhang, a professor at the College of Engineering, and Reza Ghaffarivardavagh, a Ph.D. student in the Department of Mechanical Engineering, released a paper in Physical Review B demonstrating it’s possible to silence noise using an open, ringlike structure, created to mathematically perfect specifications, for cutting out sounds while maintaining airflow.

“Today’s sound barriers are literally thick heavy walls,” says Ghaffarivardavagh. Although noise-mitigating barricades, called sound baffles, can help drown out the whoosh of rush hour traffic or contain the symphony of music within concert hall walls, they are a clunky approach not well suited to situations where airflow is also critical. Imagine barricading a jet engine’s exhaust vent—the plane would never leave the ground. Instead, workers on the tarmac wear earplugs to protect their hearing from the deafening roar.

Marine microorganisms in the Southern Ocean may find themselves in a deadly vise grip by century’s end as ocean acidification creates a shallower horizon for life, new University of Colorado Boulder research finds.

The modeling study, published today in the journal Nature Climate Change, forecasts that at current carbon dioxide emission rates, the depth at which some shelled organisms can survive will shrink from an average of 1,000 meters today to just 83 meters by the year 2100, a drastic reduction in viable habitat.

The steep drop, which could happen suddenly over a period as short as one year in localized areas, could impact marine food webs significantly and lead to cascading changes across ocean ecosystems, including disruptions of vital global fisheries.

But no other new particles have materialized at the LHC, leaving open many mysteries about the universe that the Standard Model doesn’t address. A debate has ensued over whether to build an even more enormous successor to the LHC — a proposed machine 100 kilometers in circumference, possibly in Switzerland or China — to continue the search for new physics.

Physicists say there’s much we can still learn from the Higgs boson itself. What’s known is that the particle’s existence confirms a 55-year-old theory about the origin of mass in the universe. Its discovery won the 2013 Nobel Prize for Peter Higgs and François Englert, two of six theorists who proposed this mass-generating mechanism in the 1960s. The mechanism involves a field permeating all of space. The Higgs particle is a ripple, or quantum fluctuation, in this Higgs field. Because quantum mechanics tangles up the particles and fields of nature, the presence of the Higgs field spills over into other quantum fields; it’s this coupling that gives their associated particles mass.

But physicists understand little about the omnipresent Higgs field, or the fateful moment in the early universe when it suddenly shifted from having zero value everywhere (or in other words, not existing) into its current, uniformly valued state. That shift, or “symmetry-breaking” event, instantly rendered quarks, electrons and many other fundamental particles massive, which led them to form atoms and all the other structures seen in the cosmos.
