The company’s board and the Tesla CEO hammered out the final details of his $54.20 a share bid.
The agreement marks the close of a dramatic courtship and a sharp change of heart at the social-media network.
Elon Musk acquired Twitter for $44 billion on Monday, the company announced, giving the world’s richest person command of one of its most influential social media sites — which serves as a platform for political leaders, a sounding board for experts across industries and an information hub for millions of everyday users.

Scientists demonstrate the use of a hydrogen molecule as a quantum sensor
Posted by Genevieve Klien in categories: chemistry, quantum physics
What if we could use a hydrogen molecule as a quantum sensor in a terahertz laser-equipped scanning tunneling microscope? This would allow us to measure the chemical properties of materials at unprecedented time and spatial resolutions.
This new technique has now been developed by physicists at the University of California, Irvine, according to a statement released by the institution on Friday.
“This project represents an advance in both the measurement technique and the scientific question the approach allowed us to explore,” said in the press release co-author of the new study Wilson Ho, Donald Bren Professor of physics & astronomy and chemistry.

Elon Musk’s SpaceX Signs First Deal With Major U.S. Airline To Provide Free Wi-Fi For Passengers
Posted by Kelvin Dafiaghor in categories: Elon Musk, habitats, internet, satellites
Elon Musk’s SpaceX has signed its first ever deal with a major U.S. airline to provide wireless internet to passengers for free using the Starlink satellite network.
The deal with Hawaiian Airlines, which could be implemented as soon as next year, is expected to increase pressure on rival airlines to provide free Wi-Fi for passengers.
“Hawaiian doesn’t currently offer inflight Wi-Fi and has an extensive network of flights over the Pacific Ocean, serving the mainland U.S., Japan, Australia and New Zealand, among other destinations, from Hawaii,” CNBC reported. “It plans to offer Starlink connectivity on its flights out of its home state to cities throughout the mainland U.S. and to its international destinations.”

New double neutron star millisecond pulsar discovered
Posted by Shubham Ghosh Roy in categories: physics, space
An international team of astronomers reports the discovery of a rare double neutron star millisecond pulsar. The newfound binary pulsar, designated PSR J1325−6253, consists of two neutron stars orbiting one another every 1.8 days. The finding is detailed in a paper published April 14 on arXiv.org.
The most rapidly rotating pulsars, those with rotation periods below 30 milliseconds, are known as millisecond pulsars (MSPs). It is assumed that they are formed in binary systems when the initially more massive component turns into a neutron star that is then spun-up due to accretion of matter from the secondary star.
Some pulsars consist of two neutron stars (dubbed double neutron star systems—DNS). They are one of the most important classes of objects used to test and understand numerous astrophysical and fundamental physics phenomena, including general relativity in the strong-field regime.
