Tim Cook Reveals Apple Has Used Sony Image Sensors for 10 Years

Posted by in categories: electronics, mobile phones

Apple CEO Tim Cook has revealed that the iPhone has been using Sony camera sensors for the last 10 years.

While it’s not a well-kept secret that Sony provide Apple with sensor technology, Apple tend to keep tight-lipped about the specifics of hardware components that go into the iPhone.

Apple lists the megapixels, focal length, aperture, and other specifications; but doesn’t mention identifiable hardware components.

Scientists At CERN Have just Detected A New “Ghost Particle”

Posted by in category: particle physics

Scientists are trying to work out if a strange new particle, dubbed a “ghost particle”, has been detected at CERN’s Large Hadron Collider (LHC) in Switzerland.

Using the Compact Muon Solenoid (CMS) instrument on the particle accelerator, the team said they had seen a signal that could be a particle that’s twice the mass of a carbon atom. But as the particle does not fit known theories, it could cause a bit of a stir if it exists. Their findings, which have not yet been peer-reviewed, are available on arXiv.

“I’d say theorists are excited and experimentalists are very skeptical,” Alexandre Nikitenko, a theorist on the CMS team who worked on the data, told The Guardian. “As a physicist I must be very critical, but as the author of this analysis I must have some optimism too.”

Las leyes físicas tal y como las entendemos en realidad podrían no existir

Posted by in category: futurism

Physical laws as we understand them may not actually exist.


Muchos creen que las matemáticas existen fuera de nuestras mentes y que constituyen la estructura esencial del universo. Otros piensan que las matemáticas que conocemos están muy sesgadas por las limitaciones de nuestros cerebros.

Si Sarma tiene razón, deberemos asumir que las matemáticas serían también una especie de construcción de nuestras mentes con las que, paradójicamente, hemos construido unas leyes físicas que tampoco tendrían una ontología propia. Estaríamos en un laberinto parecido al que describe Borges en sus cuentos.

Study observes Luttinger liquid behavior in a quasi-2D system

Posted by in categories: materials, quantum physics

Luttinger liquids are usually paramagnetic materials exhibiting non-Fermi liquid behavior, such as molybdenum oxides. These “liquids” and their fascinating properties had so far been only observed in 1D and quasi-1D compounds, such as blue bronze A0.3 MoO3 (A= K, Rb, Tl) and purple bronze Li0.9 Mo6O17.

Researchers at Tsinghua University, ShanghaiTech University, and other institutes in China recently observed prototypical Luttinger liquid behavior in η-Mo4O11,a charge-density wave material with a quasi-2D . Their findings, published in Nature Physics, could pave the way for the exploration of non-Fermi liquid behavior in other 2D and 3D quantum materials.

“In our previous work, we identified the Luttinger liquid phase in the normal state of blue bronzes, which is not surprising due to its quasi-1D nature,” Lexian Yang and Yulin Chen, two of the researchers who carried out the study, told Phys.org.

Atomic structure of a staphylococcal bacteriophage using cryo-electron microscopy

Posted by in category: biotech/medical

Cryo-electron microscopy by University of Alabama at Birmingham researchers has exposed the structure of a bacterial virus with unprecedented detail. This is the first structure of a virus able to infect Staphylococcus epidermidis, and high-resolution knowledge of structure is a key link between viral biology and potential therapeutic use of the virus to quell bacterial infections.

Bacteriophages or “phages” is the terms used for viruses that infect bacteria. The UAB researchers, led by Terje Dokland, Ph.D., in collaboration with Asma Hatoum-Aslan, Ph.D., at the University of Illinois Urbana-Champaign, have described atomic models for all or part of 11 different structural proteins in phage Andhra. The study is published in Science Advances.

Andhra is a member of the picovirus group. Its host range is limited to S. epidermidis. This skin bacterium is mostly benign but also is a leading cause of infections of indwelling medical devices. “Picoviruses are rarely found in phage collections and remain understudied and underused for therapeutic applications,” said Hatoum-Aslan, a phage biologist at the University of Illinois.

An AI-based platform to enhance and personalize e-learning

Posted by in categories: privacy, robotics/AI

Researchers at Universidad Autónoma de Madrid have recently created an innovative, AI-powered platform that could enhance remote learning, allowing educators to securely monitor students and verify that they are attending compulsory online classes or exams.

An initial prototype of this platform, called Demo-edBB, is set to be presented at the AAAI-23 Conference on Artificial Intelligence in February 2022, in Washington, and a version of the paper is available on the arXiv preprint server.

“Our investigation group, the BiDA-Lab at Universidad Autónoma de Madrid, has substantial experience with biometric signals and systems, behavior analysis and AI applications, with over 300 hundred published papers in last two decades,” Roberto Daza Garcia, one of the researchers who carried out the study, told TechXplore.

One of the Most Powerful Ever Detected: Astronomers Determine the Source of a Rare Massive Gamma-Ray Burst

Posted by in category: space

Scientists determine that a gamma-ray burst detected on Earth was caused by a space explosion that happened less than 900 million years ago.

On September 5, 2021, light from a very energetic gamma-ray burst (GRB) – an incredibly energetic explosion that happened in a faraway galaxy – reached our planet. To get to Earth, it traveled for more than 12.8 billion years. The glow began its journey when the Universe (which is considered to be 13.7 billion years old) was just 880 million years old.

A worldwide team of astronomers proceeded to study the explosion’s afterglow in the months that followed this finding in order to understand what caused it. Dr. Andrea Rossi, a researcher at the Italian National Institute of Astrophysics (INAF), headed the group. Professor Carole Mundell from the University of Bath was also involved.

For the First Time: Scientists Have Formed a Charged Rare Earth Molecule on a Metal Surface and Rotated It

Posted by in categories: computing, quantum physics

Scientists from Ohio University, Argonne National Laboratory, and the University of Illinois at Chicago used scanning tunneling microscopy to form a charged rare earth molecule on a metal surface and rotate it clockwise and counterclockwise without affecting its charge.

Their findings open up new avenues for research into the atomic-scale manipulation of materials important to the future, ranging from quantum computing.

For the First Time EVER: Scientists Created a Black Hole in The Lab, And Then It Started to Glow like ‘Real’ Black Holes

Posted by in categories: cosmology, mathematics, particle physics, quantum physics

Using a chain of atoms in single-file to simulate the event horizon of a black hole, a team of physicists has observed the equivalent of what we call Hawking radiation – particles born from disturbances in the quantum fluctuations caused by the black hole’s break in spacetime.

This, they say, could help resolve the tension between two currently irreconcilable frameworks for describing the Universe: the general theory of relativity, which describes the behavior of gravity as a continuous field known as spacetime; and quantum mechanics, which describes the behavior of discrete particles using the mathematics of probability.

For a unified theory of quantum gravity that can be applied universally, these two immiscible theories need to find a way to somehow get along.
