60 days.
That’s how long it will take to produce and launch a rocket if the parts are 3D printed, according to the CEO of Relativity Space, a startup that seeks to do just that.

Railroads aren’t great if they’re underwater.
Scientists have directly observed sea level rise since the late 18th century. And as they forecast the next 20, 50, and 100 years, sea level rise will continue to accelerate at an alarming rate. That rise won’t just threaten homeowners on the coast — it will also impact the critical infrastructure that supports many of our largest cities.

Google ends Pentagon contract to develop AI for recognising people in drone videos after 4,000 employees signed an open letter saying that Google’s involvement is against the company’s “moral and ethical responsibility”.
Google will not seek another contract for its controversial work providing artificial intelligence to the U.S. Department of Defense for analyzing drone footage after its current contract expires.
Google Cloud CEO Diane Greene announced the decision at a meeting with employees Friday morning, three sources told Gizmodo. The current contract expires in 2019 and there will not be a follow-up contract, Greene said. The meeting, dubbed Weather Report, is a weekly update on Google Cloud’s business.
M en with previously “untreatable” prostate cancer are being kept alive by a new drug in what experts believe may be a breakthrough for patients with the worst form of the disease.
A British trial has for the first time shown that state-of-the art immunotherapy can be used to target prostate tumours.
The study at the Royal Marsden Hospital in London found more than a third of men who had run out of existing options were still alive and one in ten had not seen their tumours grow after a year of taking Pembrolizumab, which targets a gateway helps the immune system to attack cancer cells.
A blood test could one day save millions by allowing doctors to screen for cancer before patients show symptoms.
The test, called a “liquid biopsy,” screens for 10 types of the disease by detecting trace amounts of DNA released into the bloodstream by cancer cells. So far, it has proven particularly capable of detecting ovarian and pancreatic cancer, both of which have significantly lower mortality rates when caught early enough to perform surgery as a means of removing the cancer. Unfortunately, most are caught after patients begin to show symptoms, which is often after the cancer has spread to other parts of the body.
“This is potentially the holy grail of cancer research, to find cancers that are currently hard to cure at an earlier stage when they are easier to cure,” says Dr. Eric Klein of Cleveland Clinic’s Taussig Cancer Institute. “We hope this test could save many lives.”

On August 17, 2017, astronomers witnessed an extraordinary celestial event: a collision between two ultra-dense neutron stars. Scientists had never seen anything quite like it, leading to much speculation as to what happened in the wake of the monumental encounter. New research now suggests the collision produced a black hole—but if true, it would be the lightest black hole known to science.
The thought of two neutron stars smashing into each other is nothing short of astounding. Neutron stars are stellar corpses—the remnants supernovae—and they cram a huge amount of mass into a ludicrously small sphere. Typical neutron stars are only as wide as a large city, but they’re about a half million times more massive than Earth, or about two solar masses.
A collision of two neutron stars may seem unlikely, but it happened. Data from the Laser Interferometer Gravitational Wave Observatory (LIGO) and the Virgo interferometer showed that shit got completely wild in the moments leading up to the colossal smash up. For a period of about two minutes, the binary pair spiraled around each other with unimaginable speed, spewing gravitational waves into the cosmic void. Each orbit brought the pair closer together, culminating in a collision that produced a giant shockwave.

Scientists have produced the firmest evidence yet of so-called sterile neutrinos, mysterious particles that pass through matter without interacting with it at all.
The first hints these elusive particles turned up decades ago. But after years of dedicated searches, scientists have been unable to find any other evidence for them, with many experiments contradicting those old results. These new results now leave scientists with two robust experiments that seem to demonstrate the existence of sterile neutrinos, even as other experiments continue to suggest sterile neutrinos don’t exist at all.
That means there’s something strange happening in the universe that is making humanity’s most cutting-edge physics experiments contradict one another. [The 18 Biggest Unsolved Mysteries in Physics].
