Experts in nuclear physics and quantum information have demonstrated the application of a photon-number-resolving system to accurately resolve more than 100 photons. The feat is a major step forward in capability for quantum computing development efforts. It also may enable quantum generation of truly random numbers, a long-sought goal for developing unbreakable encryption techniques for applications in, for instance, military communications and financial transactions.

Scientists studying the supermassive black hole at the heart of the M87 galaxy have revealed the origins of the monster’s powerful jet and imaged the jet and its source together for the first time. What’s more, the observations have revealed that the black hole’s ring is much larger than scientists previously believed.

A gene in the brain driving anxiety symptoms has been identified by an international team of scientists. Critically, modification of the gene is shown to reduce anxiety levels, offering an exciting novel drug target for anxiety disorders. The discovery, led by researchers at the Universities of Bristol and Exeter, is published online today [25 April] in Nature Communications.

Un equipo científico que estudió el agujero negro supermasivo presente en el corazón de la galaxia M87 reveló los orígenes de su poderoso chorro y logró obtener las primeras imágenes del chorro y su fuente juntos. Las observaciones también revelaron que el anillo del agujero negro es mucho más grande de lo que la comunidad científica creía.

A team of international researchers led by Federico Baltar of the University of Vienna and José M González of the University of La Laguna has identified a previously unknown group of bacteria, called UBA868, as key players in the energy cycle of the deep ocean. They are significantly involved in the biogeochemical cycle in the marine layer between 200 and 1000 meters. The results have now been published in the journal Nature Microbiology.

Researchers at UT Southwestern Medical Center have discovered how a bacterium that infects people after they eat raw or undercooked shellfish creates syringe-like structures to inject its toxins into intestinal cells. The findings, published in Nature Communications, could lead to new ways to treat food poisoning caused by Vibrio parahaemolyticus.

Researchers at the Icahn School of Medicine at Mount Sinai have demonstrated in a preclinical study a potential new therapeutic approach to treating the most common form of lung cancer. The strategy involves inhibiting the immune-system molecule TREM2 while enhancing natural killer cells (the so-called protectors of the immune system). It was described in the April 20 online issue of Nature Immunology.

A single species invades an ecosystem causing its collapse. A cyberattack on the power system causes a major breakdown. These type of events are always on our mind, yet they rarely result in such significant consequences. So how is it that these systems are so stable and resilient that they can withstand such external disruptions? Indeed, these systems lack a central design or blueprint, and still, they exhibit exceptionally reliable functionality.

In a study published in Nature Communications, a team led by Krembil Brain Institute at UHN Senior Scientists, Drs. Lorraine Kalia and Suneil Kalia, and University of Toronto (U of T) Professor, Dr. Philip M. Kim, identified a protein-protein interaction that contributes to Parkinson's disease. In the disease, a protein called α-synuclein (a-syn) accumulates in the brain and leads to cell death.

A new study by researchers at Washington University School of Medicine in St. Louis reveals that a connection between the body and mind is built into the structure of the brain. The study shows that parts of the brain area that controls movement are plugged into networks involved in thinking and planning, and in control of involuntary bodily functions such as blood pressure and heart rate.

Protein-protein interactions are essential for life. Researchers used DeepMind’s AlphaFold 2 to develop a deep learning approach for predicting and modeling multi-protein interactions. The AF2Complex approach generates much more accurate structural models than previous methods for modeling a protein complex. As a proof of concept, the researchers used AF2Complex to virtually screen key proteins in E. coli, discovering unexpected protein-protein interactions.

New AI tool accurately predicts both overall survival and disease-free survival after colorectal cancer diagnosis. The model uses visual markers on pathology images to glean insights into a tumor’s genomic profile and predicts tumor behavior, disease progression, treatment response. The new model could help augment clinical decision-making. Because the AI tool relies on images alone, it could be particularly valuable for hospitals lacking the technology or expertise to perform sophisticated genomic profiling of tumor tissues.

An international coalition of biomedical researchers co-led by Alexander Bick, MD, PhD, at Vanderbilt University Medical Center has determined a new way to measure the growth rate of precancerous clones of blood stem cells that one day could help doctors lower their patients’ risk of blood cancer. The technique, called PACER, led to the identification of a gene that, when activated, drives clonal expansion.
