Decoding Language from Brain Activity Non-Invasively with fMRI

Category Neuroscience

tldr

Researchers have successfully decoded language from brain activity non-invasively using fMRI scans, a feat that could facilitate communication in paralyzed individuals. The 'language decoder' was able to accurately capture and interpret auditory and imagined speech. The technology opens up new avenues for researchers to explore the underlying pathways between brain activity and language.

Solar Eruptions Led To the Genesis of Life On Earth

Category Science

tldr

A new international research study has provided evidence that the Sun's eruptions could have been a crucial element in kickstarting the precursors of life on Earth. Early-Earth's atmosphere was mixed with a 0.5-2.5% methane composition, subject to high-energy particles resulting from the Sun's superflares. This allowed for the synthesis of complex organic molecules and amino acids, essential for life.

Neutron Stars: How their merging creates gamma-ray bursts and contributes to the creation of heavy elements in the universe.

Category Space

tldr

Neutron stars are incredibly dense stars resulting from the gravitational collapse of a massive star after a supernova explosion. They have been observed to have powerful gravitational and magnetic fields, and to rotate rapidly. Scientists thought there were two varieties of Gamma-Ray Bursts (GRBs) -- long bursts associated with black holes and short bursts associated with neutron star mergers -- until a December 11, 2021 discovery showed that long bursts could also be caused by neutron star mergers. This necessitates incorporating long burst GRBs into heavy element production estimates, as they now make up an inherent part of the process of neutron star merging.

Moderating the Metaverse: A Conversation with Ravi Yekkanti

Category Technology

tldr

Ravi Yekkanti works in content moderation for virtual reality experiences, known as the metaverse. He spoke to me about how moderating in the metaverse is different than reviewing texts and videos and mentioned situations where he is taunted or bullied based on his ethnicity. Moderators need to stay undercover, prepare for different scenarios, track every event occuring in the metaverse, and report bad behavior to the client or law enforcement.

Geoffrey Hinton's Grand Retirement from Google to Gauge AI Dangers

Category Science

tldr

Geoffrey Hinton, the so-called 'Godfather of AI', has recently quit his role at Google in order to speak more directly about the potential harms of the AI technology he helped create. Hinton and other AI researchers have long expressed their concern in the lack of understanding and information of AI's capabilities and their fear over the potential dangers of AIs surpassing human intelligence and becoming commonplace in society.

Geoffrey Hinton: Stepping Down from Google, but deep learning pioneer still 'scared' of AI's potential

Category Artificial Intelligence

tldr

Geoffrey Hinton, a pioneer of deep learning and joint recipient of the 2018 Turing Award, is stepping down from Google to focus on more philosophical work related to AI's potential. Hinton's work on backpropagation and his collaboration with graduate student Ilya Sutskever and a team at Google were key for the development of large language models such as GPT-4. These developments, alongside Google's immense computing resources and team of researchers, reached levels of AI power that exceeded expectations and scared Hinton.

Iowa State researchers in psychology and engineering collaborated to explore why women experience cybersickness with virtual reality headsets more than men. Their research found that women experienced 40% more cybersickness and ended the game early twice as often as men. The second paper explored the distance between your pupils and had no bearing on the gender discrepancy. Women reported experiencing more motion sickness which increased their susceptiblity to experience cybersickness.

Understanding the Strong Nuclear Force

Category Science

tldr

The strong nuclear force is one of the four fundamental forces in the Standard Model of particle physics, and it is responsible for the stability of the atomic nucleus. It binds together the quarks that make up protons and neutrons and binds the atomic nucleus, allowing elements other than primordial hydrogen to form. The strong force is incredibly strong, even when compared to the force of gravity, and its residual force is responsible for holding the nucleus of an atom together despite the repulsive force of the protons' positive electric charge, allowing for the formation of elements and molecules.
