Those are the names of the new robots Amazon is testing with the goal of reducing strenuous movements for workers.
While the introduction of robots to the workplace often raises questions about whether human jobs will be replaced, Amazon argues they simply allow workers to focus on tasks that most need their attention while minimizing their potential for injury. Amazon said it’s added over a million jobs around the world since it began using robotics in its facilities in 2012.
In May, Amazon announced a goal of reducing recordable incident rates by 50% by 2025. It plans to invest over $300 million into safety projects this year.
Jeff Bezos’ spaceflight firm has yet to fly a single human, but one lucky auction winner has just bought the firm’s first seat for sale.
Toshiba’s Cambridge Research Laboratory has achieved quantum communications over optical fibres exceeding 600 km in length, three times further than the previous world record distance.
The breakthrough will enable long distance, quantum-secured information transfer between metropolitan areas and is a major advance towards building a future Quantum Internet.
The term “Quantum Internet” describes a global network of quantum computers, connected by long distance quantum communication links. This technology will improve the current Internet by offering several major benefits – such as the ultra-fast solving of complex optimisation problems in the cloud, a more accurate global timing system, and ultra-secure communications. Personal data, medical records, bank details, and other information will be physically impossible to intercept by hackers. Several large government initiatives to build a Quantum Internet have been announced in China, the EU and the USA.
The Atlantic is brimming with activity, and AccuWeather forecasters say things could heat up even more with a developing system that could aim for the Gulf Coast.
Researchers have developed a way to dynamically switch the surface of liquidmetal between reflective and scattering states. This technology could one day be used to create electrically controllable mirrors or illumination devices.
Liquid metals combine the electrical, thermal and optical properties of metals with the fluidity of a liquid. The new approach uses an electrically driven chemical reaction to create switchable reflective surfaces on a liquid metal. No optical coatings nor polishing steps, which are typically required to make reflective optical components, are necessary to make the liquid metal highly reflective.
In the Optical Society (OSA) journal Optical Materials Express, researchers led by Yuji Oki of Kyushu University in Japan show that switching between reflective and scattering states can be achieved with just 1.4 V, about the same voltage used to light a typical LED. The researchers collaborated with Michael D. Dickey’s research team at North Carolina State University to develop the new method, which can be implemented at ambient temperature and pressures.
What Are Telomeres?
As our cells divide (a process known as mitosis), our cells replicate the long strands of DNA located within the nucleus of our cells (known as chromosomes). This process however is imperfect, and due to the mechanics of how this is carried out by the body, the DNA is shorted ever so slightly during each replication cycle. I will not get into the details on how exactly this happens in this article, but if you are interested then this video should give you a better understanding of this process. In order to prevent important parts of the DNA being lost through the replication process, areas of what is mostly blank DNA at the end of the chromosomes are used as a sort of sacrificial buffer, allowing for the DNA to be replicated without the loss of genetic information. These areas of the chromosomes are known as telomeres. In addition to providing a buffer zone for DNA replication, telomeres also prevent broken strands of DNA attaching themselves to the ends of chromosomes, which both prevents chromosomes from becoming conjoined, as well as allowing for the opportunity for the broken strand of DNA to be repaired.
Do longer telomeres correspond to longer lifespans?
Exceptionally high-quality videos allow scientists to formally introduce a remarkable new comb jelly.
Tendrils of galaxies up to hundreds of millions of light-years long may be the largest spinning objects in the universe, a new study finds.
