Protons’ antimatter is even more lopsided than we thought

The proton’s antimatter is out of whack. An imbalance between two types of antiparticles that seethe within the proton is even wonkier than previously thought, a new measurement indicates. Protons are built from t­hree quarks — two “up” quarks and one “down” quark. But they also contain a roiling sea of transient quarks and antiquarks […]

Cygnus X-1 was the First Black Hole Ever Found. New Measurements Show it’s Much More Massive Than Previously Believed

In 1964 two Aerobee suborbital rockets were launched with the goal of mapping x-ray sources in the sky. Each rocket contained a directed Geiger counter, so that as the rocket rotated at the peak of its trajectory to measure the direction of x-ray sources. The project discovered eight x-ray sources, including a particularly bright one […]

Conservatives aren’t more fearful than liberals, study finds

Are conservatives more afraid of threats than liberals? Political psychologists have long found evidence that people on the right are more sensitive to scary stuff, on average, than people on the left, a basic psychological difference thought to drive some political disagreements between the two groups.  But new research suggests that’s overly simplistic.  In a […]

‘Homegrown’ California coronavirus variant is more contagious and possibly deadlier

Scientists in California are increasingly worried about the state’s “homegrown” coronavirus variant, with studies now showing that the variant is more transmissible than earlier strains and may be more resistant to current vaccines, according to news reports. The variant, known as B.1.427/B.1.429, first emerged in California last spring but didn’t show up on scientists’ radar […]

More Than 87,000 Scientific Papers Published on Coronavirus Since Start of COVID Pandemic

Scientists from around the world have published more than 87,000 papers about coronavirus between the start of the COVID-19 pandemic and October 2020, a new analysis shows. Even given the importance of the pandemic, researchers were surprised by the huge number of studies and other papers that scientists produced on the subject in such a […]

Breeding Better Seeds: Sustainable, More Nutritious Food Production Under the Specter of Global Warming

Researchers used genetic engineering to create a type of cotton seed without a substance that is toxic to humans. Now humans can eat these cotton seeds, which are a great source of protein and fiber.

The first black hole ever discovered is more massive than previously thought

The first black hole ever discovered still has a few surprises in store. New observations of the black hole–star pair called Cygnus X-1 indicate that the black hole weighs about 21 times as much as the sun — nearly 1.5 times heavier than past estimates. The updated mass has astronomers rethinking how some black hole–forming […]

First Black Hole Ever Detected – Cygnus X-1 – Is Much More Massive Than We Thought

New observations of the first black hole ever detected have led astronomers to question what they know about the Universe’s most mysterious objects. Published today (February 18, 2021) in the journal Science, the research shows the system known as Cygnus X-1 contains the most massive stellar-mass black hole ever detected without the use of gravitational […]

COVID-19 Genetic Mutation D614G Makes the Virus Up to 8x More Infectious

SARS-CoV-2  D614G mutation, now ubiquitous, increases virus’ ability to infect human cells. D614G mutation in the SARS-CoV-2 spike protein, now ubiquitous, increases virus’ ability to infect human cells. A mutation in the spike protein of SARS-CoV-2—one of several genetic mutations in the concerning variants that have emerged in the United Kingdom, South Africa, and Brazil—makes […]

New Timeline for Mars Terrains: NASA’s Perseverance Rover Predicted to Encounter More Ancient Surfaces

An SwRI scientist used a new model to estimate Mars’ bombardment history. This new model indicated that some of the most prominent terrains associated with ancient water activity may be hundreds of millions of years older than previously thought, important data as NASA’s Perseverance rover prepares to land in one of these craters. The image […]
