Your ears enjoy music but your heart may also benefit, according to a new study presented at the American College of Cardiology's Annual Scientific Session.

Patients with early post-infarction angina, episodes of chest pain after a heart attack, reported 
significantly lower levels of anxiety and pain if they listened to music for 30 minutes a day. While that's hard to pin down biologically, 700,000 people survive a heart attack just in the U.S. each year and roughly 1 in 9 heart attack survivors experience subsequent episodes of chest pain and anxiety within the first 48 hours, so whatever works to reduce that.

We haven't had a widespread flu problem since 2018. Yet despite it only being 2020, some insist this year's coronavirus must be the product of government scientists, though some also suggest it was the result of 5G cellular service in Wuhan. Then China claimed it might be the U.S.

What is the truth?

The novel SARS-CoV-2 coronavirus that emerged in the city of Wuhan is the product of natural evolution, finds an analysis of genome sequence data from SARS-CoV-2 and related viruses published today.

Stegosaurs are among the most recognizable dinosaurs because they left a lasting impression, including on a Scottish island.

Analysis of footprints show stegosaur roamed the Isle of Skye about 170 million years ago. it wasn't an isle then, it was a long-lost island in the Atlantic, and the site on the north-east coast was at the time a mudflat on the edge of a shallow lagoon. It contains a mixture of footprints, which means dinosaurs on Skye were more diverse than known. 

In Ukraine and the west Russian Plain, there remain mysterious bone circles made from the remains of dozens of mammoths long ago. 

About 70 of them are known to exist. One, outside the modern village of Kostenki 250 miles south of Moscow, has been dated to 20,000 years in the past, making it the oldest such circular structure built by humans. A total of 51 lower jaws and 64 individual mammoth skulls were used to construct the walls of the 30 foot by 30 foot structure, now called Kostenki 11, and scattered across its interior. The bones were likely sourced from animal graveyards, and the circle was then hidden by sediment and is now a foot below current surface level.

Though implicit bias - the belief that you are prejudiced, it's just a matter of degree - is controversial, that's only because it lacks scientific footing. A new study seeks to advance that.

We all have likes and dislikes but when it becomes bias or prejudice is subjective. If you prefer dark haired men, does that mean you are prejudiced against redheads? It does, in things like the Implicit Association Test. 

Drosophila flies lose long-term memory of a traumatic event when kept in the dark, and the authors of a new study link that to a specific molecular mechanism responsible. 

Memories are difficult to erase but breakthroughs could be important for sufferers of trauma, because while most normal events won't be recalled even the same day, a particularly shocking event may be consolidated into our long-term memory, whereby new proteins are synthesized and the neuronal circuits in our brain are modified.
