Astronomers detect new Jupiter-like exoplanet

Posted by in category: space

Using radial velocity measurements, astronomers from Japan and China have detected a new exoplanet orbiting a G-type giant star. The newfound alien world is similar in mass to Jupiter but much hotter than the solar system’s biggest planet. The discovery is reported in a paper published November 12 on the arXiv pre-print server.

The radial velocity (RV) method to detect an is based on the detection of variations in the velocity of the central star, due to the changing direction of the gravitational pull from an unseen exoplanet as it orbits the star. Thanks to this technique, more than 600 exoplanets have been detected so far.

Now, a group of astronomers led by Huan-Yu Teng of the Tokyo Institute of Technology in Tokyo, Japan, reports the finding of a new giant planet as a result of RV measurements using the HIgh Dispersion Echelle Spectrograph (HIDES) at Okayama Astrophysical Observatory (OAO) in Japan. The planet orbits a deeply evolved solar-mass G-type known as HD 167,768, located some 353 away.

SpaceX just launched one of its boosters for the 11th time

Posted by in categories: alien life, satellites

SpaceX sent one of its first-stage boosters skyward for the 11th time on Tuesday evening. However, unlike its 10 previous flights, this time it didn’t return.

The mission launched from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida at 9:57 p.m. ET, lighting up the night sky as the Falcon 9 rocket roared toward space.

Thirty-five minutes after leaving the launchpad, the Falcon 9’s second stage deployed a communications satellite to a geosynchronous transfer orbit for French satellite operator Eutelsat.

Mind-Machine Interfaces

Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/
The ability to link mind and machine has long been the realm of science fiction, but now improvements in our understanding may allow us to network brain to computer in the near future. Companies like Neurolink have begun to explore how to link our neurons to machine, and we’ll explore now such neural interfaces might function and how they might change our lives.

How Your Brain’s “Fingerprints” Could Diagnose Disease

Posted by in categories: biotech/medical, neuroscience

This new way to diagnose schizophrenia, epilepsy, Alzheimer’s disease and autism spectrum disorder could help improve mental health. We often think of fingerprints as the tiny ridges, whorls and arched patterns on the tip of each finger. They are heralded as special markers of human identity, even more individualized than DNA.

Quantum algorithms save time in the calculation of electron dynamics

Posted by in categories: chemistry, computing, information science, quantum physics

Researchers have investigated the capability of known quantum computing algorithms for fault-tolerant quantum computing to simulate the laser-driven electron dynamics of excitation and ionization processes in small molecules. Their research is published in the Journal of Chemical Theory and Computation.

“These quantum algorithms were originally developed in a completely different context. We used them here for the first time to calculate electron densities of , in particular their dynamic evolution after excitation by a ,” says Annika Bande, who heads a group on at Helmholtz Association of German Research Centers (HZB). Bande and Fabian Langkabel, who is doing his doctorate with her, show in the study how well this works.

“We developed an algorithm for a fictitious, completely error-free quantum computer and ran it on a classical server simulating a quantum computer of ten qubits,” says Langkabel. The scientists limited their study to smaller molecules in order to be able to perform the calculations without a real quantum computer and to compare them with conventional calculations.

How polio came back to New York for the first time in decades, silently spread and left a patient paralyzed

Posted by in categories: biotech/medical, health

It’s difficult to trace the epidemiology since the patient didn’t travel, the mutations in the viruses are small and international travel in and out of New York is heavy, he said.

“With a single case there’s no way to know exactly how many infections there were between the vaccine vial and the paralyzed person,” Oberste said.

It’s unlikely public health authorities will figure out the origin of the virus that paralyzed the patient in New York, Oberste said. Dozens of countries around the world — primarily in Africa, the Middle East and South Asia — are still using oral vaccines that contain the Sabin Type 2 strain.

Fractal animations with quantum computing on a Raspberry Pi

Posted by in categories: computing, quantum physics

By Wiktor Mazin, Jan-Rainer Lahmann, Emil Reinert and Bengt Wegner

Creators are increasingly using Qiskit to make works of quantum art. And, combined with the Raspberry Pi, you have a unique platform to create portable installations beyond the realm of your laptop.

For this project, Wiktor Mazin, Jan-Rainer Lahmann, Emil Reinert and Bengt Wegner teamed up to demonstrate quantum fractals on the Raspberry Pi. We hope to show how to get creative with quantum computers thanks to the portability and ease-of-use of the RasQberry project, while providing a short guide on how you can create your own fractal animations using python code with Qiskit, both via a direct link and via an install on a Raspberry Pi.

NASA returns to the Moon: Orion Spacecraft completes lunar flyby

Posted by in category: space

On its journey to a world-record-breaking orbit, NASA’s Orion spacecraft, which had test dummies in place of people, buzzed the lunar surface and whipped around the far side.

It marks a significant accomplishment in the $4.1 billion test journey that started last Wednesday and is the first time a capsule has reached the moon in 50 years.

The crew capsule and its three wired-up dummies maneuvered within 81 miles of the Moon on the far side.
