Black Holes Feed On Quantum Foam, Says Cosmologist — The Physics arXiv Blog
If Spaans is right, black holes grow by feeding on spacetime itself and their quantum feeding habits effectively solve the problem of how the biggest black holes become so massive, so quickly. “Supermassive black holes can acquire a lot of their mass through these quantum contributions over the life time of the universe,” he says. Here’s some useful background. In 1955, the American theoretical physicist John Wheeler suggested that at very small length scales, virtual particles, including quantum black holes, must constantly jump in and out of existence creating a kind of foamy structure that is very different from the smooth spacetime we see at larger scales. Nobody has ever observed quantum foam but there is widespread agreement that the fabric of the universe must be made of something like it. In ordinary circumstances, quantum foam has little impact. Spaans’ approach is to ask what happens when a black hole meets quantum foam. And that ought to be measurable.

New Type of Star Emerges From Inside Black Holes — The Physics arXiv Blog
Black holes have fascinated scientists and the public alike for decades. There is special appeal in the idea that the universe contains regions of space so dense that light itself cannot escape and so extreme that the laws of physics no longer apply. What secrets can these extraordinary objects hide? Today, we get an answer thanks to the work of Carlo Rovelli at the University of Toulon in France, and Francesca Vidotto at Radboud University in the Netherlands. These guys say that inside every black hole is the ghostly, quantum remains of the star from which it formed. Rovelli and Vidotto call these objects “Planck stars” and say they could solve one of the most important questions in astrophysics. Black holes arise naturally from Einstein’s theory of general relativity which predicts that gravity influences the trajectory of photons moving through space. Astrophysicists have long believed that black holes form when stars a little bigger than the Sun run out of fuel.

Biomedical science courses and careers in the UK - i-studentglobal
Biomedical science honours degree courses have been producing highly skilled and flexible graduates in the UK for over forty years. UK biomedical science honours degrees have proven to be extremely popular with both employers and students as an academically rigorous and stimulating degree programme that offers a wide range of career opportunities upon graduation. The first Masters programmes in biomedical science in the UK were established in the mid-1980s and have been growing in popularity ever since. Today there are over 50 UK universities offering biomedical science undergraduate degree programmes and over 40 offering biomedical science Masters courses. “Biomedical scientist” is a statutorily protected title in the UK. UK honours degree courses in biomedical science that are accredited by either the IBMS or approved by the HCPC will meet the HCPC’s criteria for registration.

There’s An Awesome Trick You Can Do To Get To Sleep In Under 1 Minute | Viral Thread
It was the week before my best friend’s wedding, and my anxiety levels had hit the roof. A thousand thoughts were racing around my mind. Like most of us, I had a lot on my plate. I wasn’t sleeping, not even a little. Part of that had to do with the best man speech I was due to give in front of all my friends. I was terrified and could not shut my brainbox off at night, it was a really bore. After day three of lying awake until the wee hours of the morning, I sheepishly admitted to my friend (the groom) that I was too nervous to kip. It couldn’t be more simple and easily applicable. He explained that the considered combination of numbers has a chemical-like effect on our brains, and would slow my heart rate and soothe me right to sleep. How it Works I couldn’t wait to put the trick to the test, and to my complete disbelief, I woke up the next morning unable to even remember getting to the eighth second of the exhale because it knocked me out that fast.

12 Habits Of Students Who Get A First | Uni Baggage
12 Habits Of Students Who Get A First With more graduates than ever before entering the job market year on year, degree classifications have never been so important. And I’m guessing that’s EXACTLY what you want to hear just a few weeks before exam season. Please stop crying. We didn’t mean to upset you. Did you know that it’s not just just strange hobbit people with giant brains and odd mature students who get firsts at university? That’s right, REAL people can get a first… if they want one. (*We should mention that we will take no responsiblity if you adopt these habits and still don’t get a first. 1. Hands up if you’ve ever rewarded yourself for revising by taking a hard earned nap? 2. Students who get firsts DO NOT waste time making folders on their desktops and trying to pretend to themselves that this is actually useful. 3. 4. 5. And when I say sleep I don’t mean nap. 6. Successful students don’t wait until the ‘are you still watching?’ 7. 8. 9. via @amanda.san on Instagram 10. 11.
Everything we eat both causes and prevents cancer
In an effort to illustrate how often medical studies can be flawed, Vox have put together the above graph showing how, in a single meta-analysis of research into food-cancer risk links, you can get some very different results depending on how you designed your experiment. You can see the full version below. The image is based on a 2013 paper called "Is everything we eat associated with cancer? A systematic cookbook review", for which the researchers randomly selected 50 ingredients from a cookbook and looked into recent studies that evaluated the relation of each to cancer risk. Reporting in The American Journal of Clinical Nutrition, they found that 40 of the ingredients had articles reporting on their cancer risk, and of 264 single-study assessments they looked at, 191 (72 percent) concluded that the tested food was associated with an increased or decreased risk. If none of that sounds quite right - it shouldn't. Source: Vox
