Hubble Space Telescope at 30: Astronaut Mike Massimino looks back at fixing a space icon

Posted by in category: space

Thirty years ago this week — on April 24, 1990 — the Hubble Space Telescope launched into space and opened humanity’s eyes to the cosmos. Now, we reflect on how this groundbreaking instrument has changed and evolved our understanding of the universe.

Space.com spoke to retired NASA astronaut Mike Massimino, who currently serves as the senior advisor for space programs at the Intrepid Sea, Air and Space Museum, about his experiences working with the telescope and its importance to science and society.

Pocket-sized device tests DNA in blood samples for genetic conditions

Posted by in categories: 3D printing, biotech/medical, genetics, mobile phones

It is now possible to use a cheap, lightweight and smartphone-powered DNA detector to identify DNA in blood, urine and other samples, on the spot.

At the moment, testing to identify DNA is usually done in laboratories using expensive, specialised equipment. To make this process faster and cheaper, Ming Chen at the Army Medical University in China and his colleagues developed a portable DNA detector made of 3D-printed parts that attach to a standard smartphone.

Elon Musk says Starlink internet private beta to begin in roughly three months, public beta in six

Posted by in categories: Elon Musk, internet, satellites

SpaceX CEO and founder Elon Musk has shared more details about when in 2020 we can expect the company’s Starlink low-latency, high-bandwidth satellite internet service to actually be available to customers. He said on Twitter that a private beta for Starlink would begin in around three months, with a public beta to kick off roughly three months after that.

The initial beta test will apply to those located in “high latitudes,” Musk added. To date, SpaceX has said that Starlink service will initially be made available to customers in Canada and in the northern United States in 2020, with additional service expansion to follow to other parts of the world throughout 2021. On Twitter in response to a question about whether Germany counts as “high latitude,” Musk said that it does, indicating beta service at least may be available in more markets than the U.S. and Canada ahead of next year.

Late last year, Musk tweeted saying he was using a Starlink satellite connection to do so, and since then the company has launched six batches of 60 satellites each to build out its network. The small satellites work by flying around the Earth in low orbit, passing off connection between one another to ensure consistent service is provided to ground stations. They orbit lower than geostationary communications satellites, which provides latency and speed benefits, but don’t remain in a fixed position so a large number of them are required to provide consistent connectivity.

Elon Musk hypes up Tesla smart home HVAC, hints at Cybertruck feature

Posted by in categories: Elon Musk, energy, sustainability, transportation

Elon Musk seems to be really interested in Tesla expanding into the home HVAC industry — going as far as saying that he is “dying to do it.”

He first brought up the idea in an interview on the Joe Rogan Experience almost two years ago.

CRISPR combines with stem cell therapy to reverse diabetes in mice

Posted by in categories: biotech/medical, genetics

For a few years now, scientists at Washington University have been working on techniques to turn stem cells into pancreatic beta cells as a way of addressing insulin shortages in diabetics. After some promising recent strides, the team is now reporting another exciting breakthrough, combining this technique with the CRISPR gene-editing tool to reverse the disease in mice.

The pancreas contains what are known as beta cells, which secrete insulin as a way of tempering spikes in blood-sugar levels. But in those with diabetes, these beta cells either die off or don’t function as they should, which means sufferers have to rely on diet and or regular insulin injections to manage their blood-sugar levels instead.

One of the ways scientists are working to replenish these stocks of pancreatic beta cells is by making them out of human stem cells, which are versatile, blank slate-like cells that can mature into almost any type of cell in the human body. The Washington University team has operated at the vanguard of this technology with a number of key breakthroughs, most recently with a cell implantation technique that “functionally cured” mice with diabetes.

Scientists compile the first comprehensive geological map of the Moon

Posted by in category: satellites

Drawing on data from satellites and Apollo-era missions, scientists at the US Geological Survey (USGS), NASA and the Lunar Planetary Institute have pieced together what they say is the first comprehensive geological map of the Moon.

Our 4.5-billion-year-old satellite is adorned with all kinds of rocks, craters and other interesting geological features. To dig into the details, the scientists looked to regional maps from six Apollo missions and combined these with modern data from recent satellite missions.

Refreshing the historical maps with fresh scientific observations enabled the scientists to put together an incredibly detailed perspective of the Moon, showing its geology at a scale of 1:5,000,000.
