https://phys.org/news/2019-01-magnetar-mysteries-galaxy.html Magnetar mysteries in our galaxy and beyond January 10, 2019, California Institute of Technology: In a new Caltech-led study, researchers from campus and the Jet Propulsion Laboratory (JPL) have analyzed pulses of radio waves coming from a magnetar—a rotating, dense, dead star with a strong magnetic field—that is located near the supermassive black hole at the heart of the Milky Way galaxy. The new research provides clues that magnetars like this one, lying in close proximity to a black hole, could perhaps be linked to the source of "fast radio bursts," or FRBs. FRBs are high-energy blasts that or…

https://phys.org/news/2019-01-student-simulates-thousands-black-holes.html Student simulates thousands of black holes January 9, 2019, University of Arizona: Lia Medeiros, a doctoral student at the University of Arizona, is developing mathematical models that will allow researchers to pit Einstein's Theory of General Relativity against the most powerful monsters of nature: supermassive black holes such as Sgr A*, which lurks at the center of the Milky Way. Medeiros has developed a diagnostic tool that astronomers can use to compare upcoming observations of supermassive black holes by the Event Horizon Telescope to the predictions of mathematical models…

Scientists determined the source was a black hole caught in the midst of an outburst—an extreme phase in which a black hole can spew brilliant bursts of X-ray energy as it devours an avalanche of gas and dust from a nearby star. Now astrono…

https://phys.org/news/2019-01-evidence-gigantic-star-explosions.html First evidence of gigantic remains from star explosions January 9, 2019, Lancaster University Astrophysicists have found the first ever evidence of gigantic remains being formed from repeated explosions on the surface of a dead star in the Andromeda Galaxy, 2.5 million light years from Earth. The remains or "super-remnant" measures almost 400 light years across. For comparison, it takes just 8 minutes for light from the Sun to reach us. A white dwarf is the dead core of a star. When it is paired with a companion star in a binary system, it can potentially produce a nova explosion. If …

https://phys.org/news/2019-01-astronomers-evidence-white-dwarf-stars.html Astronomers discover first direct evidence of white dwarf stars solidifying into crystals January 9, 2019, University of Warwick The first direct evidence of white dwarf stars solidifying into crystals has been discovered by astronomers at the University of Warwick, and our skies are filled with them. Observations have revealed that dead remnants of stars like our Sun, called white dwarfs, have a core of solid oxygen and carbon due to a phase transition during their lifecycle similar to water turning into ice but at much higher temperatures. This could make them potentially billi…

Interesting article on science (mainly space science) in 2019. https://medium.com/starts-with-a-bang/top-10-highlights-of-what-2019-will-hold-for-science-469db3315e2f It includes this great composite picture to show the relative size of the Moon and the shadow of the Earth:

I'm going to post this here, it is a short video about bacteria movement and super fluids but I have seen something similar in real life. I used to culture euglena as a food source for rotifers, in the culture barrels the euglena would swim around and round the barrels and almost always they would all go the same direction actually making a visible current that would carry small floating particles on the surface around visibly moving at several inches a minute. These microscopic protists creating this current as long as the sun shone on them I think was similar to what is being said here.

The mission will be a pioneering look at the far side of the moon – a region that is forever hidden from the Earth, since we see the same side all of the time. Even messages cannot be relayed easily from that distant area, and it has remained unexplored by any rover.https://www.independent.co.uk/news/science/china-moon-far-side-dark-change4-landing-time-location-space-craft-a8708186.html

The ‘third pole’ is the planet’s largest reservoir of ice and snow after the Arctic and Antarctic. It encompasses the Himalaya–Hindu Kush mountain ranges and the Tibetan Plateau. The region hosts the world’s 14 highest mountains and about 100,000 square kilometres of glaciers (an area the size of Iceland). Meltwater feeds ten great rivers, including the Indus, Brahmaputra, Ganges, Yellow and Yangtze, on which almost one-fifth of the world’s population depend..https://www.nature.com/articles/d41586-018-07838-4

A study has suggested that the big bang doesn't start or end in a singularity and that time can be extended back to beyond the beginning of the universe that we see! https://www.sciencealert.com/mind-bending-study-suggests-time-did-actually-exist-before-the-big-bang

In January, US and UK researchers will descend on Antarctica to begin their largest joint mission to the continent in more than 70 years. The aim of the five-year project is to understand whether the remote and seemingly unstable Thwaites Glacier will start to collapse in the next few decades. Elephant seals carrying sensors will help researchers to gather ocean data as part of a massive mission to study Antarctica’s Thwaites glacier.https://en.wikipedia.org/wiki/Thwaites_Glacier https://www.nature.com/articles/d41586-018-07847-3

A superconducting transition temperature (Tc) of between 260 K and 280 K was realized in a pressurized compound of lanthanum and hydrogen, they did use 2 million times the atmospheric pressure at Earth’s surface to achieve it. Although a room-temperature superconductor that requires 200 gigapascals of pressure wouldn’t be at all useful outside the lab, it could provide a road map for formulating another material that behaves similarly at ambient pressure.https://physicstoday.scitation.org/do/10.1063/PT.6.1.20180823b/full/ I'm curious to whether this has an effect on Cooper pairing.

So, if you guys don't know, starlite is a super heat resistant material that was under serious review by Nasa for use as one of the worlds most effective heat shields. However, the guy who knew the recipe died and we never figured out what it was. It had ridiculous properties that we haven't even come close to being able to replicate. Except, this guy on this youtube channel put out a video show casing what he believes to be starlite, and even explains how to make it so you can test it out for yourself. Thoughts? Is this real?

The French Dossier on TiO2 was made publically available on 31st May 2016. They are trying to make it a class 1 B Carcinogen by inhalation based on some test they did on rats in 1985 by Lee et al. The test was critiqued by many as rats aren't a great indicator in carcinogen tests for humans and the rats were overloaded with huge amounts of the powder. Here is some background as to their proposal. It seems there still needs to be testing done on the nano form, but no-one, outside of the Lee et al French experiments in 1985 has shown any harm caused by normal industrial use of TiO2 powder. A larger debacle is that if they get their proposal through, then, paint form…

Nuru was prepared for the worst when she went to get screened for HIV eight years ago. After caring for her mother in Uganda, who died as a result of the virus, Nuru moved to the United Kingdom to study, and decided to take her health into her own hands. “I was ready to be told I had HIV,” she says. “I felt, ‘That’s okay. I’ve looked up to my mother’.” What she didn’t expect was to be diagnosed with a different viral infection altogether: hepatitis B. “The way the health worker delivered it to me, it was like, ‘It’s worse than HIV’. I was confused, I was suicidal,” says Nuru (who asked that her real name not be used for this article). “I just didn’t understand what i…

Two more universities in Japan have admitted to systematically favouring male applicants to their medical degrees over women. The revelations come four months after reports that Tokyo Medical University had been altering the results of its entrance examination for years to keep the proportion of female entrants below 30% of all students.The news sparked outrage in the country, and prompted a government investigation to examine whether the practice was used at other medical schools. https://www.nature.com/articles/d41586-018-07769-0

https://phys.org/news/2018-12-luca-universal-common-ancestor.html Looking for LUCA, the last universal common ancestor December 18, 2018 by Keith Cooper, NASA Around 4 billion years ago there lived a microbe called LUCA: the Last Universal Common Ancestor. There is evidence that it could have lived a somewhat 'alien' lifestyle, hidden away deep underground in iron-sulfur rich hydrothermal vents. Anaerobic and autotrophic, it didn't breathe air and made its own food from the dark, metal-rich environment around it. Its metabolism depended upon hydrogen, carbon dioxide and nitrogen, turning them into organic compounds such as ammonia. Most remarkable of all, t…

To this day, that 1968 mission is considered to be NASA's boldest and perhaps most dangerous…

Neuroscientists have amassed more evidence for the hypothesis that sticky proteins that are a hallmark of neurodegenerative diseases can be transferred between people under particular conditions — and cause new damage in a recipient’s brain. They stress that their research does not suggest that disorders such as Alzheimer’s disease are contagious, but it does raise concern that certain medical and surgical procedures pose a risk of transmitting such proteins between humans, which might lead to brain disease decades later. “The risk may turn out to be minor — but it needs to be investigated urgently,” says John Collinge, a neurologist at University College London…

https://phys.org/news/2018-12-volume-universe-factor.html Innovation increases observable volume of the universe by a factor of seven December 14, 2018, GEO600 Gravitational Wave Detector: The detection of Einstein's gravitational waves relies on highly precise laser measurements of small length changes. The kilometer-size detectors of the international network (GEO600, LIGO, Virgo) are so sensitive that they are fundamentally limited by tiny quantum mechanical effects. These cause a background noise which overlaps with gravitational-wave signals. This noise is always present and can never be entirely removed. But one can change its properties –…
