How We’ll Reach a 1 Trillion Transistor GPU

Posted by in category: computing

Largely thanks to advances in semiconductor technology, a measure called energy-efficient performance is on track to triple every two years (EEP units are 1/femtojoule-picoseconds).

In particular, the EEP increase will be enabled by the advanced packaging technologies we’ve been discussing here. Additionally, concepts such as system-technology co-optimization (STCO), where the different functional parts of a GPU are separated onto their own chiplets and built using the best performing and most economical technologies for each, will become increasingly critical.

Practical Quantum Devices Now Closer to Reality — Scientists Unveil Room Temperature Photonic Chips

Posted by in categories: computing, encryption, quantum physics

A new study by Hebrew University has made a significant breakthrough by successfully incorporating single-photon sources into small chips that operate at room temperature. This development marks a crucial progress in the field of quantum photonics, opening up possibilities for its use in quantum computing and cryptography. It represents a key achievement in creating usable quantum photonic devices, signaling an optimistic outlook for the complete realization of quantum technologies, including computing, communication, and sensing.

A recent study, spearheaded by Boaz Lubotzky during his Ph.D. research, along with Prof. Ronen Rapaport from the Racah Institute of Physics at The Hebrew University of Jerusalem, in collaboration with teams from Los Alamos National Laboratory (LANL) in the USA and from Ulm University in Germany, unveiled a significant advancement toward the on-chip integration of single-photon sources at room temperature. This achievement represents a significant step forward in the field of quantum photonics and holds promise for various applications including quantum computing, cryptography, and sensing.

Chilling Findings: Scientists Shed Light on How the Brain Perceives Temperature

Posted by in categories: food, neuroscience

Christian Lemon, Ph.D., an associate professor in the School of Biological Sciences at the University of Oklahoma, often thinks about temperature sensation and the brain when eating a chilled mint cookie. Now, research from his lab examining oral temperature perception has been published in The Journal of Neuroscience.

In their research, Lemon’s team investigates how cold receptors in the mouth are activated by cooling temperatures, how those signals are transmitted to the brain and how those transmissions are generated into a cooling sensation.

Revolutionary Silicon Spikes Destroy 96% of Viruses on Contact

Posted by in categories: biotech/medical, nanotechnology

An international research team led by RMIT University has designed and manufactured a virus-killing surface that could help control disease spread in hospitals, labs, and other high-risk environments. The surface made of silicon is covered in tiny nanospikes that skewer viruses on contact.

Lab tests with the hPIV-3 virus – which causes bronchitis, pneumonia, and croup – showed 96% of the viruses were either ripped apart or damaged to the point where they could no longer replicate to cause infection. These impressive results, featured on the cover of top nanoscience journal ACS Nano, show the material’s promise for helping control the transmission of potentially dangerous biological material in laboratories and healthcare environments.

Groundbreaking Study Reveals Hidden Brain Risks in Heart Disease Patients

Posted by in categories: biotech/medical, health, neuroscience

A new analysis involving over 13,000 people has found changes to blood vessels in the brain that can increase the risk of stroke and dementia are common in people with a range of heart conditions, regardless of whether they have experienced a stroke.

The new research, published in Neurology, the medical journal of the American Academy of Neurology, is the most comprehensive systematic review of ‘hidden’ brain changes in people with a range of heart conditions to date.

Lead author Dr Zien Zhou from The George Institute for Global Health said that identifying these changes could play an important role in choosing treatments for these patients.
