A New Contender for the Theory of Everything

Posted by in categories: particle physics, quantum physics, space

The most popular contender over the past few decades has been string theory, and the related concepts of superstring theory and M-theory, in which particles are considered as tiny units of one-dimensional string. However, a lesser-known theory has also gained traction; loop quantum gravity (LQG), which attempts to solve the quantum gravity problem by focusing on the very fabric of spacetime, rather than the particles themselves.

In “Quantum Space,” the popular-science writer Jim Baggott lays out the basic principles of LQG for science enthusiasts. The book looks at how loop quantum gravity has emerged by following the work of two of its leading proponents, Carlo Rovelli and Lee Smolin, and assesses where the theory is now, and where it might be going.

Although the concepts are — not surprisingly — mind-boggling, Baggott asks deep questions about the nature of the universe, what space is actually composed of, and the existence of time itself. (The book covers a lot of challenging material, however, and some prior reading may help readers find their way.)

NASA released a stunning photo showing two galaxies colliding

Posted by in category: space

The galaxies have never before been captured in such detail.


First discovered in 1784 by William Herschel, NGC 6052 was originally thought to be a singular galaxy that simply had an odd shape.

However, scientists eventually figured out that the “oddly shaped galaxy” 230 million light-years away was, in fact, two galaxies in the process of colliding.

This company wants to deliver a baby in space and prepare humanity for a life beyond Earth

Posted by in categories: biotech/medical, education, satellites

What happens when Earth’s resources run out? Well, if science fiction has taught us anything, it’s that humanity will seek a new and habitable planet somewhere in the cosmos on which to keep the species going in perpetuity. When that day comes, we’ll need a viable way to procreate and deliver children in the vastness of outer space.

Enter SpaceLife Origin, a one-of-a-kind tech company that is seeking to make it possible for humans to give birth in the vacuum of space by 2024, a goal titled “Mission Cradle.” While that is its ultimate goal, SpaceLife is also striving to become the first company to “safe-guard human ‘Seeds-of-Life’ in space [Mission Ark] by 2020 [and] make embryo conception in space feasible [Mission Lotus] by 2021,” according to its official website.

The gallery below offers a glimpse at the patent-pending “Ark” designs. Vials of human DNA will be protected within the radiation-shielded spheres that are to be kept on Earth and satellites surrounding the planet. SpaceLife Origin describes this as an insurance policy for the continuation of mankind in case a catastrophe hits and we need to leave in a hurry.

Supercomputers help supercharge protein assembly

Posted by in categories: biotech/medical, supercomputing

Red blood cells are amazing. They pick up oxygen from our lungs and carry it all over our body to keep us alive. The hemoglobin molecule in red blood cells transports oxygen by changing its shape in an all-or-nothing fashion. Four copies of the same protein in hemoglobin open and close like flower petals, structurally coupled to respond to each other. Using supercomputers, scientists are just starting to design proteins that self-assemble to combine and resemble life-giving molecules like hemoglobin. The scientists say their methods could be applied to useful technologies such as pharmaceutical targeting, artificial energy harvesting, ‘smart’ sensing and building materials, and more.

Google is hosting a global contest to develop AI that’s beneficial for humanity

Posted by in categories: quantum physics, robotics/AI

The Quantum Flagship was first announced in 2016, and on 29 October, the commission announced the first batch of fund recipients. The 20 international consortia, each of which includes public research institutions as well as industry, will receive a total of €132 million over 3 years for technology-demonstration projects.


One of the most ambitious EU ‘Flagship’ schemes yet has picked 20 projects, aiming to turn weird physics into useful products.

Quantum optical cooling of nanoparticles

Posted by in categories: nanotechnology, particle physics, quantum physics

When a particle is completely isolated from its environment, the laws of quantum physics start to play a crucial role. One important requirement to see quantum effects is to remove all thermal energy from the particle motion, i.e. to cool it as close as possible to absolute zero temperature. Researchers at the University of Vienna, the Austrian Academy of Sciences and the Massachusetts Institute of Technology (MIT) are now one step closer to reaching this goal by demonstrating a new method for cooling levitated nanoparticles. They now publish their results in the renowned journal Physical Review Letters.

Tightly focused can act as optical “tweezers” to trap and manipulate tiny objects, from glass to living cells. The development of this method has earned Arthur Ashkin the last year’s Nobel prize in physics. While most experiments thus far have been carried out in air or liquid, there is an increasing interest for using to trap objects in ultra-high vacuum: such isolated particles not only exhibit unprecedented sensing performance, but can also be used to study fundamental processes of nanoscopic heat engines, or phenomena involving large masses.

A key element in these research efforts is to obtain full control over the particle motion, ideally in a regime where the laws of quantum physics dominate its behavior. Previous attempts to achieve this, have either modulated the optical tweezer itself, or immersed the particle into additional light fields between highly reflecting mirror configurations, i.e. optical cavities.
