No-go for show: Jeff Bezos’ Blue Origin delays spaceship test due to bad O-ring
Amazon billionaire Jeff Bezos says his Blue Origin space venture is delaying its first live-streamed space launch due to a leaky O-ring seal.

The bacterial DnaA-trio replication origin element specifies single-stranded DNA initiator binding
DNA replication is tightly controlled to ensure accurate inheritance of genetic information. In all organisms, initiator proteins possessing AAA+ (ATPases associated with various cellular activities) domains bind replication origins to license new rounds of DNA synthesis. In bacteria the master initiator protein, DnaA, is highly conserved and has two crucial DNA binding activities. DnaA monomers recognize the replication origin (oriC) by binding double-stranded DNA sequences...

Jeff Bezos’ Blue Origin does it again: Used rocket goes into space and lands intact
Amazon founder Jeff Bezos’ Blue Origin space venture sent up its New Shepard suborbital spaceship on another flight test to outer-space altitudes today, and brought it back to a safe landing. The uncrewed flight at Bezos’ West Texas test...
Virgin Galactic’s Richard Branson ribs space billionaires amid Blue Origin buzz
Amazon founder Jeff Bezos’ Blue Origin space venture may have done another flight test, and Elon Musk’s SpaceX is making waves with its rocket progress – but don’t forget about Richard Branson. “Our spaceship comes back and lands on wheels. Theirs don’t,” the billionaire founder of Virgin...
Weakened magnetic braking as the origin of anomalously rapid rotation in old field stars
A knowledge of stellar ages is crucial for our understanding of many astrophysical phenomena, and yet ages can be difficult to determine. As they become older, stars lose mass and angular momentum, resulting in an observed slowdown in surface rotation. The technique of ‘gyrochronology’ uses the rotation period of a star to calculate its age. However, stars of known age must be used for calibration,...

Ammoniated phyllosilicates with a likely outer Solar System origin on (1) Ceres
Studies of the dwarf planet (1) Ceres using ground-based and orbiting telescopes have concluded that its closest meteoritic analogues are the volatile-rich CI and CM carbonaceous chondrites. Water in clay minerals, ammoniated phyllosilicates, or a mixture of Mg(OH)2 (brucite), Mg2CO3 and iron-rich serpentine have all been proposed to exist on the surface. In particular, brucite has been suggested from analysis of the mid-infrared spectrum...
