Massive asteroids — including one the size of the Empire State Building — are predicted to make “close” encounters with Earth in the coming weeks, with one set to whiz by as early as Wednesday night.

The space rock “2004 UE,” which at 1,246 feet is only a few feet shorter than the Midtown skyscraper, will be 2.6 million miles away on Nov. 13.

Of the asteroids headed our way, “1996 VB3” — which has a diameter of about 750 feet — is expected to come closest to Earth, at a distance of only 2.1 million miles, according to NASA’s Center for Near-Earth Objects.

Conventional lung cancer treatments include surgery, chemotherapy and radiotherapy; however, these treatments are often poorly tolerated by patients. Cannabinoids have been studied for use as a primary cancer treatment. Cannabinoids, which are chemically similar to our own body’s endocannabinoids, can interact with signalling pathways to control the fate of cells, including cancer cells. We present a patient who declined conventional lung cancer treatment. Without the knowledge of her clinicians, she chose to self-administer ‘cannabidiol (CBD) oil’ orally 2–3 times daily. Serial imaging shows that her cancer reduced in size progressively from 41 mm to 10 mm over a period of 2.5 years. Previous studies have failed to agree on the usefulness of cannabinoids as a cancer treatment. This case appears to demonstrate a possible benefit of ‘CBD oil’ intake that may have resulted in the observed tumour regression. The use of cannabinoids as a potential cancer treatment justifies further research.

Field doctors still diagnose burns by sight, smell and touch. A smart bandage and smart phone camera may be all we need to change that — and prevent serious and lasting complications.

The supernova remanent is located about 19,600 light years away from Earth.

A new image by Chandra reveals a rare supernova remanent created by a white dwarf accumulating material from another star until it explodes.

Raptor and BE4SpaceX and Blue Origin have been competing with each other for many space crafts and commercial contracts. We have also talked about their rivalry many times but today is all about their engines that fire up the massive rockets both the companies are developing. SpaceX, the leading space company has made many rocket engines since its launch in 2002. A few months ago, SpaceX completed its 100th Raptor Engine. This extraordinary milestone was achieved in just 29 months. Blue Origin’s rocket engines game started work on the BE-4 in 2011. Importantly, they said the “BE-4 would be ‘ready for flight’ by 2017″, but at this moment Blue Origin’s powerful BE-4 engine is more than four years late. The first flight test of the new engine is now expected no earlier than 2022 on the Vulcan rocket. This is a big problem and we need to talk about that.
So, How did Blue Origin’s BE-4 turn into a joke whereas SpaceX’s Raptor is the leading example?
Let’s find out:
Firstly, how has BE-4 gone through almost a decade of failure?
This was their first engine to combust liquid oxygen and liquified natural gas propellants. It was initially planned for the engine to be used exclusively on a Blue Origin proprietary launch vehicle New Glenn, the company’s first orbital rocket. However, it was announced in 2014 that the engine would also be used on the United Launch Alliance (ULA) Vulcan Centaur launch vehicle, the successor to the Atlas V launch vehicle. This was labeled “a stunner” choice. The company planned to begin full-scale engine testing in late 2016 and expected to complete the development of the engine in 2017.However, the first engine was not fully assembled until March 2017. Also, in March, United Launch Alliance indicated that the economic risk of the Blue Origin engine selection option had been retired, but that the technical risk on the project would remain until a series of engine firing tests were completed later in 2017. A test anomaly occurred on 13 May 2017 and Blue Origin reported that they lost a set of powerpack hardware.
SpaceX’s Raptor Engines completely HUMILIATED Blue Origin BE-4 Engines!!

Researchers at the University of California, Berkeley, have successfully revived human heart tissue after it had been preserved in a subfreezing, supercooled state for up to three days.

A truck fleet accident costs an average of $16,500 in damages and $57,500 in injury-related costs for a total of $74,000. “This does not include a broad range of ‘hidden’ costs, including reduced vehicle value (typically anywhere from $500 to $2,000), higher insurance premium, legal fees, driver turnover (the average driver replacement cost = $8,200), lost employee time, lost vehicle-use time, administrative burden, reduced employee morale and bad publicity,” said Yoav Banin, chief product officer at Nauto, which provides artificial intelligence driver and fleet performance solutions.

Emphasis on truck driving safety is well placed, considering other challenges that the trucking industry is facing.

Ranking first is a chronic shortage of truck drivers nationwide that could force fleet operators to hire less-experienced drivers who require operator and safety training. Driver compensation and truck parking ranked second and third, but immediately behind them in fourth and fifth position were driver truck fleet safety and insurance availability, which depends on safe driving records.

Artificial intelligence expert Timnit Gebru on the challenges researchers can face at Big Tech companies, and how to protect workers and their research.

Artificial intelligence research leads to new cutting-edge technologies, but it’s expensive. Big Tech companies, which are powered by AI and have deep pockets, often take on this work — but that gives them the power to censor or impede research that casts them in an unfavorable light, according to Timnit Gebru, a computer scientist, co-founder of the nonprofit organization Black in AI and the former co-leader of Google’s Ethical AI team.

The situation imperils both the rights of AI workers at those companies and the quality of research that is shared with the public, said Gebru, speaking at the recent EmTech MIT conference hosted by MIT Technology Review.
