A New Type of Cataclysmic Event in the Cosmos: Astrophysicists Detect First Black Hole-Neutron Star Mergers

Posted by in categories: cosmology, physics

Mix pair is “elusive missing piece of the family picture of compact object mergers.”

A long time ago, in two galaxies about 900 million light-years away, two black holes each gobbled up their neutron star companions, triggering gravitational waves that finally hit Earth in January 2020.

Discovered by an international team of astrophysicists including Northwestern University researchers, two events — detected just 10 days apart — mark the first-ever detection of a black hole merging with a neutron star. The findings will enable researchers to draw the first conclusions about the origins of these rare binary systems and how often they merge.

Europe considering concepts for human spaceflight

Posted by in category: space travel

A bumper crop of applications for the ESA’s astronaut corps is providing a boost to proposals for Europe to develop its own human spaceflight capability.


WASHINGTON — A bumper crop of applications for the European Space Agency’s astronaut corps is providing a boost to proposals for Europe to develop its own human spaceflight capability.

ESA announced June 23 that it received 22589 applications in a solicitation that ended June 18. That’s far more than the 8413 applications it received in the previous astronaut selection round in 2018.

Wow! NASA photographer spots space station crossing the sun during spacewalk (video)

Posted by in categories: energy, space

The mosaic image is a composition of seven subsequent frames taken from Nellysford, Virginia, as the space station traversed the face of the sun at the speed of roughly 5 miles per second, which is about 18000 mph (29000 kph), according to a NASA photo description.

The six-hour and 45-minute spacewalk was the third for Pesquet and Kimbrough in less than two weeks as they completed work on augmenting the space station’s power systems. The iROSA panel deployed on Friday was the second of six new panels to be installed at the station.

Friday’s extravehicular activity (EVA) positioned the second iROSA opposite the first on the far left, or port side of the space station’s backbone truss. Now both the 2B and 4B power channels on the port 6 (P6) truss have the new arrays deployed.

Billionaire bitcoin investor Tim Draper: 1 question he always asks before investing—and why he sometimes gets ‘3 hours of sleep’

Posted by in categories: bitcoin, finance, space travel

“I’m at [email protected],” he tells CNBC Make It. He gives it out to everyone because he likes helping people and it keeps him on top of his game.

“I end up learning things that I never imagined I’d want to know,” Draper says.

Draper is a legend in the world of venture capital. Since the mid-1980s, he has built a fortune making early investments in companies like Hotmail, Skype, Baidu, Tesla and SpaceX.

Sequencing 101: Whole Genome Sequencing for Rare Diseases

Posted by in categories: biotech/medical, genetics

Big fan of long-read sequencing. It helped diagnose my rare disease when conventional sequencing failed.

What’s the Difference between Short-Read Sequencing and Long-Read Sequencing? Like their names suggest, short-read sequencing looks at DNA in short snippets (100−350 base pairs) while long-read sequencing measures long fragments of DNA (tens of thousands of base pairs). Why does that matter? Well, when trying to characterize a human genome that has two copies (one maternal and one paternal), each 3.2 billion base pairs in length — having longer snippets of DNA means you: Need fewer snippets to make up the length of the whole genome and have no gaps where the sequence is unknown Can more easily map how one region of the genome is connected to another region Have the ability to phase or determine which copy of a gene, maternal or paternal, a mutation occurs in.


PacBio long-read sequencing provides the most comprehensive view of genomes, transcriptomes, and epigenomes.

Shock find brings extinct mouse back from the dead

Posted by in category: biotech/medical

An Australian mammal thought to have been wiped out over 150 years ago can now be crossed off our list of extinct animals, following a new study.

Researchers compared DNA samples fromeight extinct Australian rodents, as well as 42 of their living relatives, to look at the decline of native species since the arrival of Europeans in Australia.

The study showed the extinctGould’s was indistinguishable from the Shark Bay mouse, still found on several small islands off the coast of Western Australia.

6 Tips to Reduce Carcinogenic Barbecue Health Risks

Posted by in category: life extension

Short of ceasing your grilling activity, there’s no way to completely avoid AGEs, PAH, and HCA when enjoying a summer barbecue. That said, there’s plenty you can do to reduce your carcinogen risk while enjoying smokey flavors over the summer.

Hickory and oak wood and charcoal are the scents of summer. I associate that campfire smell with fireworks, screaming with neighborhood kids while jumping through a lawn sprinkler, and Dad at the grill with a Blue Moon in hand. Barbeque is a wonderful pastime. So help me, nothing will pry it out of my red-blooded American hands, especially not on the Fourth of July.

Railroads To Pour Cold Renewable Energy Water On Koch Industries

Posted by in categories: business, chemistry, energy, sustainability, transportation

The US power grid needs all of support it can get. Sad that some would stand in the way of progress.


There is no love lost between the notorious Koch brothers and the nation’s railroad industry, and the relationship is about to get a lot unlovelier. A massive new, first-of-its-kind renewable energy transmission line is taking shape in the Midwest, which will cut into the Koch family’s fossil energy business. It has a good chance of succeeding where others have stalled, because it will bury the cables under existing rights-of-way using railroad rights-of-way and avoid stirring up the kind of opposition faced by conventional above-ground lines.

The Koch brothers and their family-owned company, Koch Industries, have earned a reputation for attempting to throttle the nation’s renewable energy sector. That makes sense, considering that the diversified, multinational firm owns thousands of miles of oil, gas, and chemical pipelines criss-crossing the US (and sometimes breaking down) in addition to other major operations that depend on rail and highway infrastructure.
