Physicists who built ultrafast ‘attosecond’ lasers win Nobel Prize

Posted by in categories: biological, chemistry, particle physics, quantum physics

This year’s Nobel Prize in Physics has been awarded to three physicists — Pierre Agostini at Ohio State University, US, Ferenc Krausz at the Max Planck Institute of Quantum Optics in Garching, Germany, and Anne L’Huillier at Lund University, Sweden — for their research into attosecond pulses of light.

Attosecond physics allows scientists to look at the very smallest particles at the very shortest timescales (an attosecond is one-quintillionth of a second, or one-billionth of a nanosecond). The winners all developed experiments to be able to produce these ultrafast laser pulses, which can be used to probe our world at the smallest scales and have applications across chemistry, biology and physics.

The prize was announced this morning by the Royal Swedish Academy of Sciences, in Stockholm, Sweden. The winners share a prize of 11 million Swedish kroner (US$1 million).

Efforts to create ultrafast light pulses win 2023 physics Nobel

Posted by in categories: particle physics, quantum physics

Congrats to Anne & Pierre.

Inside atoms and molecules, electrons zip around at extreme speeds. Their motions can only be captured with super short pulses of light — like camera flashes that last billionths of a billionth of a second. The 2023 Nobel Prize in physics goes to three physicists who have helped create such “attosecond” blasts of laser light.

By offering superfast snapshots of electrons, their research is changing our view of the inner workings of atoms and molecules.

What Constitutes Your Stream of Consciousness?

Posted by in categories: information science, mobile phones, neuroscience, singularity

It wouldn’t shock me if all the buzz around searching for the ‘locus of consciousness’ merely fine-tunes our grasp of how the brain is linked to consciousness — without actually revealing where consciousness comes from, because it’s not generated in the brain. Similarly, your smartphone doesn’t create the Internet or a cellular network; it just processes them. Networks of minds are a common occurrence throughout the natural world. What sets humans apart is the impending advent of cybernetic connectivity explosion that could soon evolve into a form of synthetic telepathy, eventually leading to the rise of a unified, global consciousness — what could be termed the Syntellect Emergence.

In summary, the study of consciousness could be conceptualized through a variety of lenses: as a series of digital perceptual snapshots, as a cybernetic system with its feedback processes, as a grand theater; or perhaps even as a VIP section in a cosmological establishment of magnificent complexity. Today’s leading theories of consciousness are largely complementary, not mutually exclusive. These multiple perspectives not only contribute to philosophical discourse but also herald the dawn of new exploratory avenues, equally enthralling and challenging, in our understanding of consciousness.

Scientists Discover a Completely New Type of Enzyme That Helps Fight Genomic Parasites

Posted by in categories: biotech/medical, genetics

Professor René Ketting’s team at the Institute of Molecular Biology (IMB) in Mainz, Germany, along with Dr. Sebastian Falk’s group at the Max Perutz Labs in Vienna, Austria, have discovered a new enzyme, PUCH, which plays a key role in preventing the spread of parasitic DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Quantum Leap: Researchers Achieve Major Milestone for Reliable Quantum Computers

Posted by in categories: computing, quantum physics

In a breakthrough for the futuristic field of quantum computing, researchers have implemented a basic arithmetic operation in a fault-tolerant manner on an actual quantum processor for the first time. In other words, they found a way to bring us closer to more reliable, powerful quantum computers less prone to errors or inaccuracies.

Quantum computers harness the bizarre properties of quantum physics to rapidly solve problems believed to be impossible for classical computers. By encoding information in quantum bits or “qubits,” they can perform computations in parallel, rather than sequentially as with normal bits.

Meta to charge users in EU for ad-free Instagram and Facebook

Posted by in category: futurism

Meta is preparing to charge EU users a $14 monthly subscription fee to access Instagram on their phones unless they allow the company to use their personal information for targeted ads.

The US tech giant will also charge $17 for Facebook and Instagram together for use on desktop, said two people with direct knowledge of the plans, which are likely to be rolled out in coming weeks.

The move comes after discussions with regulators in the bloc who have been seeking to curb the way big tech companies profit from the data they get from their users for free, which would be a direct attack on the way groups such as Meta and Google generate their profits.

TikTok testing out advert-free monthly subscription

Posted by in category: futurism

The BBC understands the Chinese firm is trying out the service in an English-speaking market outside the US, but has declined to comment on exactly where.

The subscription is being tested at $4.99 (£4.13).

Meanwhile, Meta is reportedly mulling ad-free subscriptions for people in the EU to navigate the bloc’s advertising rules.
