Taste is a complex phenomenon. We do not experience the sensation through a single sense (as we would when we see something using our sense of sight, for example) but rather it is made up of the five senses working together to allow us to appreciate and enjoy food and drink. Initial visual inspection of food indicates if we would consider consuming it. Then, when eating, smell and flavor combine to allow us to perceive a taste. Meanwhile, the mix of ingredients, texture and temperature can further impact how we experience it.
If you've swum in the ocean you know it requires a lot of energy, and for ships it is no different. Adding to that are the problems of friction, corrosion, and biofilms, all of which cause marine traveler to drag.
Science is on the case. New types of ship coatings that permanently retain an air layer under water and reduce the three problems have been granted the Validation Award by the Federal Ministry of Education and Research (BMBF) in Germany.
Supplements are a huge industry that ballooned after President Bill Clinton turned the Dietary Supplement Health and Education Act of 1994 into law and took control of the controversial industry away from the U.S. Food and Drug Administration in return for a weak disclaimer that the FDA had not evaluated their claims - "This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease" all while suggesting they do exactly that.
It is a bit embarrassing to post here a graph of boring elementary particle signals, when the rest of the blogosphere is buzzing after the release of the first real black hole image from the Event Horizon collaboration. So okay, before going into pentaquarks, below is the image of the black hole at the center of M87, a big elliptical galaxy 54 million light years away.
Published in 1979 in Astronomy and Astrophysics, it had a worldwide impact, especially since this type of object was still highly theoretical.
It was not an artist's view but an image based on the then supposed physical properties of a black hole and its gas disc, such as its rotation rate and temperature, and on Einstein's general theory of relativity.
An international team of over 200 scientists has captured the first direct images of a black hole. They accomplished this remarkable feat by coordinating the power of eight major radio observatories on four continents, to work together as a virtual, Earth-sized telescope.
In a series of papers published today in a special issue of Astrophysical Journal Letters, the team has revealed four images of the supermassive black hole at the heart of Messier 87, or M87, a galaxy within the Virgo galaxy cluster, 55 million light years from Earth.
All four images show a central dark region surrounded by a ring of light that appears lopsided — brighter on one side than the other.
The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole.
Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.
Am debunking this page because it makes a scary prediction of a 10 °C rise by 2026. It is very very silly. By far the silliest post I’ve seen on climate change, and that’s saying something, I’ve seen some ridiculous posts, but this takes the biscuit. I can’t find out anything about Sam Carana who runs this blog, but he would flunk high school maths and physics if he gave material like this in answer to exam questions.
This is not about the IPCC report which is often misunderstood as saying something similar. For the journalistic misunderstandings of the 2017 IPCC report see my
Approximately a million people in the U.S. are living with HIV and up to 15 percent may not even know they are infected. In Februrary, the U.S. Department of Health and Humans Services announced a new initiative, Ending the HIV Epidemic: A Plan for America, to reduce new infections by 75 percent in the next five years and by 90 percent in the next ten years, averting more than 250,000 HIV infections in that span.
In the movie "Erin Brockovich", actress Julia Roberts portrayed a clerk who got energy company PG&E worried enough about a jury being scared of science they wrote her boss a giant check. Because Hollywood is in California, the state government was motivated to declare the compound harmful and put in tighter restrictions.
The concern from the science community was that no one was being harmed. It's a slippery slope from demonizing a scary sounding chemical in water to doing the same thing to vaccines or weedkillers. Which is exactly what has happened, and California has led the way in both cases.
