Hello everyone, for a university course I am currently collecting research articles in the field of biomedicine/genetics/molecular biology. I am particularly interested in papers which have been published within the last 15 years or so and which represent cornerstones of the life sciences. The articles are thought to be presented by the participating students in a "journal club" format. I was already thinking of the Yamanaka/ipSCs paper from 2007; the brainbow mouse paper(Livet et al, 2007), the essential genes of a minimum bacterial cell and first "synthetic cell" by Craig Venter's people and more recently, the 2012 CRISPR paper from Doudna's and Charpentier's group…

NASA team studies middle-aged Sun by tracking motion of Mercury January 18, 2018 by Elizabeth Zubritsky, NASA's Goddard Space Flight Center Like the waistband of a couch potato in midlife, the orbits of planets in our solar system are expanding. It happens because the Sun's gravitational grip gradually weakens as our star ages and loses mass. Now, a team of NASA and MIT scientists has indirectly measured this mass loss and other solar parameters by looking at changes in Mercury's orbit. The new values improve upon earlier predictions by reducing the amount of uncertainty. That's especially important for the rate of solar mass loss, because it's …

https://phys.org/news/2018-01-neutron-star-merger-yields-puzzle-astrophysicists.html Neutron-star merger yields new puzzle for astrophysicists January 18, 2018, McGill University: The afterglow from the distant neutron-star merger detected last August has continued to brighten - much to the surprise of astrophysicists studying the aftermath of the massive collision that took place about 138 million light years away and sent gravitational waves rippling through the universe. New observations from NASA's orbiting Chandra X-ray Observatory, reported in Astrophysical Journal Letters, indicate that the gamma ray burst unleashed by the collisio…

https://phys.org/news/2018-01-massive-neutron-stars.html#ms How massive can neutron stars be? Astrophysicists at Goethe University Frankfurt set a new limit for the maximum mass of neutron stars: They cannot exceed 2.16 solar masses. Since their discovery in the 1960s, scientists have sought to answer an important question: How massive can neutron stars actually become? By contrast to black holes, these stars cannot gain in mass arbitrarily; past a certain limit there is no physical force in nature that can counter their enormous gravitational force. For the first time, astrophysicists at Goethe University Frankfurt have succeeded in calculating a st…

As car autopilots become common, it seems some things now done at fixed locations, such as stores and warehouses, will become mobile. Eventually, food may be picked and delivered to your door without stopping at a store or warehouse, including fresh food and prepared. It will cut costs. There will be similar things done with durable goods, but this segment of the market seems more difficult to fully mobilize.

According to this Physicist Illinios article: "Professor of Physics Peter Abbamonte and graduate students Anshul Kogar and Mindy Rak, with input from colleagues at Illinois, University of California, Berkeley, and University of Amsterdam, have proven the existence of this enigmatic new form of matter, which has perplexed scientists since it was first theorized almost 50 years ago." "So what exactly is excitonium? Excitonium is a condensate—it exhibits macroscopic quantum phenomena, like a superconductor, or superfluid, or insulating electronic crystal. It’s made up of excitons, particles that are formed in a very strange quantum mechanical pairing, namely that …

However, the physics of tilted discs (e.g. angular momentum transport and jet formation) is poorly understood. Using our new GPU-accelerated code H-AMR, we performed 3D general relativistic magnetohydrodynamic simulations of tilted thick accretion discs around rapidly spinning BHs…

Gravitational waves measure the universe January 8, 2018, Harvard-Smithsonian Center for Astrophysics NGC4993, the galaxy hosting the gravitational wave event GW170817 that has been used to measure the age of the universe. The source of the event is the red dot to the upper left of the galaxy's center; it was not there in earlier images. Credit: NASA and ESA The direct detection of gravitational waves from at least five sources during the past two years offers spectacular confirmation of Einstein's model of gravity and space-time. Modeling of these events has also provided information on massive star formation, gamma-ray bursts,…

NIH scientists find most potent, wide-reaching HIV antibody so-far known. Researchers at the National Institutes of Health have isolated an antibody from an HIV-positive patient that is capable of neutralizing 98 percent of HIV strains. It’s a success rate that makes it easily the most potent, wide-reaching HIV antibody and one that may have profound implications for the treatment and prevention of the disease. The group’s work is published in the current issue of the journal Immunity. https://source247.net/2017/10/15/new-antibody-neutralizes-nearly-every-hiv-strain/ read more here.

"Theoretical physicist Stephen Hawking has already asserted that humans need to colonize a new planet soon — and now he’s arguing that we need to start within 100 years to keep the species alive. Hawking will lay out his reasoning for why and how people must start inhabiting another planet in a BBC program airing this summer called Stephen Hawking: Expedition New Earth. He has theorized in the past that the chance of a disaster on Earth adds up over time, so that it’s a “near certainty” in the next 1,000 or 10,000 years, but the human race will survive if it expands into outer space. “With climate change, overdue asteroid strikes, epidemics and population growth…

Einstein's equation E=MC2 is reversible within the deep gravity wells of massive (Supermassive, Megamassive) Black Holes so that mass and energy come to equilibrium within the event horizon. This hypothesis permits a steady-state continuous Universe. The hypothesis is self-published via 'Smashwords' or by emailing me at tobyclark1@hotmail.com. There are two papers available entitled "Megamassive Black Holes & the Steady-State Universe and "The Recycling Universe"

An aneutronic reaction is being proposed for a new fusion reactor that would not emit neutrons and it's energy could be turned directly into electrical power with no steam turbines involved. https://www.livescience.com/61298-new-fusion-reactor-uses-boron-and-hydrogen.html?utm_source=notification

In 2017, scientists detected Einstein's gravitational waves from a new source - the collision of two dead stars, or neutron stars. The first direct detection of these waves was announced in 2016 when the Advanced LIGO laboratories described the warping of space from the merger of two distant black holes. The result was hailed as the starting point for a new branch of astronomy, using gravitational waves to collect data about distant phenomena. Telescopes from all over the world captured details of the neutron star merger as it unfolded. The outburst took place in a galaxy located roughly a thousand billion, billion km away in the Constellation Hydra. Some of the fact…

MACHOs are dead. WIMPs are a no-show.

Or is a misunderstanding of what space is, and how gravity works.
