Physicists could be on the verge of a major breakthrough as new results hint at a challenge to the standard model of particle physics.
There are now more than 1300 Starlink satellites in orbit.
CAPE CANAVERAL, Fla. — A SpaceX Falcon 9 rocket launched a new batch of 60 Starlink internet satellites into orbit early Wednesday (March 24) and nailed a landing at sea to top off the company’s latest successful mission.
The veteran Falcon 9 rocket blasted off from Space Launch Complex 40 here at Cape Canaveral Space Force Station in Florida at 4:28 a.m. EDT (0828 GMT).
Summary: Combining neuroimaging data with artificial intelligence technology, researchers have identified a complex network within the brain that comprehends the meaning of spoken sentences.

Have you ever wondered why you are able to hear a sentence and understand its meaning – given that the same words in a different order would have an entirely different meaning?
Should interest those into links on aging/longevity and neuroscience.
The mammalian center for learning and memory, hippocampus, has a remarkable capacity to generate new neurons throughout life. Newborn neurons are produced by neural stem cells (NSCs) and they are crucial for forming neural circuits required for learning and memory, and mood control. During aging, the number of NSCs declines, leading to decreased neurogenesis and age-associated cognitive decline, anxiety, and depression. Thus, identifying the core molecular machinery responsible for NSC preservation is of fundamental importance if we are to use neurogenesis to halt or reverse hippocampal age-related pathology.
While there are increasing number of tools available to study NSCs and neurogenesis in mouse models, one of the major hurdles in exploring this fundamental biological process in the human brain is the lack of specific NSCs markers amenable for advanced imaging and in vivo analysis. A team of researchers led by Dr. Mirjana Maletić-Savatić, associate professor at Baylor College of Medicine and investigator at the Jan and Dan Duncan Neurological Research Institute at Texas Children’s Hospital, and Dr. Louis Manganas, associate professor at the Stony Brook University, decided to tackle this problem in a rather unusual way. They reasoned that if they could find proteins that are present on the surface of NSCs, then they could eventually make agents to “see” NSCs in the human brain.

Following on in the vein of my recent topics, this week I am looking at mTOR. A crucial protein that performs the function of an enzyme that is critical for day to day function. There are so many terms and words, subjects and strategies, abound, and so many talk in terms where a basic understanding of the subject is necessary to benefit fully, that I decided to create a kind of library, or resource where you can brush up on all the core fundamentals. Should you stimulate mTOR or seek to restrict it? What will happen if I do? Is this a short term strategy or a lifestyle goal? And what is the real state of the science that underpins it all? These are all questions you, or friends, may have, or even may have heard but been unable to answer fully or concisely, hopefully these will help to reduce those issues. Next week I will be looking at its partner in crime, AMPK, together they exist in balance like a playground see-saw… Until then, have an amazing day…
In this video I will look at what mTOR is and how you can harness it to benefit your objectives. By controlling it we can achieve the balance we need which is to grow muscle to stay fit and strong, but also to not burn out too quickly, so we can live a long healthy life, with a long health span. Maximising anti aging to aid in longevity is delicate balance unique to us all and which varies depending on our current goals and objectives.

“Whooshes of creation” may be producing multiverses at this moment, says astronomer.
The cosmic inflation credited with creating the homogeneous universe which we now enjoy was likely not a one-off event, University of California, Berkeley astronomer Alexei Filippenko, told me. In fact, these ‘whooshes of creation’ may be producing multiverses even at this moment, says Filippenko.
The idea of an exponential, faster-than-light expansion of the early universe, was first put forth by MIT astrophysicist Alan Guth in 1981. And today, Inflation theory is used to explain the Cosmos’ current size, expansion, homogeneity and the fact that it appears to be geometrically flat, I noted in a 2011 issue of Astronomy magazine.
