For the first time, researchers have demonstrated a way to map and measure large-scale photonic quantum correlation with single-photon sensitivity. The ability to measure thousands of instances of quantum correlation is critical for making photon-based quantum computing practical.
In Optica, The Optica l Society’s journal for high impact research, a multi-institutional group of researchers reports the new measurement technique, which is called correlation on spatially-mapped photon-level image (COSPLI). They also developed a way to detect signals from single photons and their correlations in tens of millions of images.
“COSPLI has the potential to become a versatile solution for performing quantum particle measurements in large-scale photonic quantum computers,” said the research team leader Xian-Min Jin, from Shanghai Jiao Tong University, China. “This unique approach would also be useful for quantum simulation, quantum communication, quantum sensing and single-photon biomedical imaging.”
Questions about using technologies like CRISPR to gene edit human embryos gained immediacy last month, when Chinese scientists claimed to have edited the genes of two babies in order to protect them against HIV — a move that prompted an international outcry, but also questions about when the technology will be ready for human testing.
“People appear to realize there’s a major question of how we should oversee and monitor use of this technology if and when it becomes available,” Columbia University bioethicist Robert Klitzman told the AP of the new research. “What is safe enough? And who will determine that? The government? Or clinicians who say, ‘Look, we did it in Country X a few times and it seems to be effective.

“It’s dangerous to directly correlate things like, ‘This is a brain!’” Gimzewski told ZDNet. “It’s exhibiting electrical characteristics which are very similar to a functional MRI of brains, similar to the electric characteristics of neuronal cultures, and also EEG patterns.”

A rare set of semi-identical twins – only the second set ever reported in the world – have been identified in Australia.
The now 4-year-old boy and girl from Brisbane share all of their mother’s DNA but only a part of their father’s DNA, making them identical on their mother’s side but fraternal on their father’s, a statement detailing the discovery said.
This was also the first time semi-identical twins have been identified during pregnancy, according to a case report recently published in the New England Journal of Medicine.
In order to remain healthy and functional, cells have a number of maintenance systems that help them to dispose of metabolic waste and unwanted proteins. Autophagy is perhaps the best-known example of how cells purge their waste, and another is the ubiquitin-proteasome system (UPS). Researchers are working on ways to boost the activity of the UPS to improve cellular health.
The ubiquitin-proteasome system
During normal cellular function, proteins being constructed in the cell can sometimes become misfolded and start to accumulate over time, which can cause the cell to become dysfunctional and encourage diseases such as Alzheimer’s to develop as the system gums up with bent and broken proteins.
Michelle Khine is a professor of biomedical engineering at the University of California, Irvine. Nine months ago, her newborn son was hospitalized for complications during childbirth and was admitted to the neonatal intensive care unit (NICU). While in the NICU, her son was connected to several machines that were supplying oxygen and monitoring his breathing.
A biomedical engineering research team from the University of California has developed a new wearable respiratory sensor to monitor children with chronic pulmonary conditions. The design was built with inspiration from a favorite childhood toy, Shrinky Dinks.
Your genome literally identifies you, but researchers and genetic firms keep saying that DNA data is anonymous. It’s a privacy scandal waiting to happen.

EVERY person in the world is issued with a unique code before they are even born. Governments, insurance firms and indeed pretty much anyone can use this code to catalogue us throughout our entire lives. This isn’t a sci-fi dystopia – it is just genetics.
