Google’s Brain Division And DeepMind Merges

Google is no longer treating artificial intelligence like a side project—Microsoft and OpenAI have seen to that with the public availability of ChatGPT. Google has already started reorganizing to improve its Bard AI. As part of this effort, it’s merging its two AI research groups into one; Google Brain and …

Apple Watch Blood Glucose Monitor

Apple still has a long way to go before it adds no-prick blood glucose monitors to its wearables, Bloomberg’s Mark Gurman reported Sunday. Gurman said Apple “still needs to perfect the algorithms and on-board sensors” found in its prototypes before even hoping to build them into a Watch. It also …

Scientists Create 3D Printed Hearts

But what if doctors could reduce wait times and the odds of rejection by having a heart custom printed for each patient? That’s the goal of five biomedical engineers at MIT, who have found a way to 3D print functioning hearts. Each of their soft robotic hearts can be configured …

Quantum Chromodynamics

In particle collider experiments, elementary particle interactions with large momentum transfer produce quarks and gluons (known as partons) whose evolution is governed by the strong force, as described by the theory of quantum chromodynamics. These partons subsequently emit further partons in a process that can be described as a parton …

Triple J-Psi Meson

Physicists from the Compact Muon Solenoid (CMS) Collaboration at CERN’s Large Hadron Collider (LHC) have observed three J/ψ particles emerging from a single collision between two protons. A proton-proton collision event with six muons (red lines) produced in the decays of three J/ψ particles. Image credit: CMS / CERN. The …

Novel Tests New Physics

Physicists from CERN’s LHCb (Large Hadron Collider beauty) Collaboration have carried out new tests of lepton universality, one of the basic principles of the Standard Model of particle physics. This principle states that the Standard Model treats the three charged leptons — electrons, muons and taus — identically, except for …

Physicists Unprecedented Precision

Physicists have performed an improved measurement of the free neutron lifetime using the UCNτ apparatus at the Los Alamos Neutron Science Center. Their results, published in the journal Physical Review Letters, represent a more than two-fold improvement over previous measurements. Gonzalez et al. report an improved measurement of the free …

Quantum Teleportation

Quantum teleportation of an unknown input state from an outside source onto a quantum node is considered one of the key components of long-distance quantum communication protocols. It has already been demonstrated with pure photonic quantum systems as well as atomic and solid-state spin systems linked by photonic channels. Now, …

Exotic Indium Nuclei

The isotope tin-100 is of interest for nuclear structure due to its closed-shell proton and neutron configurations. It is also the heaviest nucleus comprising protons and neutrons in equal numbers. In new research, physicists from the ISOLTRAP experiment at CERN’s Isotope mass Separator On-Line (ISOLDE) facility performed direct mass measurements …

Superionic Water’s

Using machine learning, a team of physicists at Lawrence Livermore National Laboratory has studied the phase behaviors of superionic water — a phase of water where hydrogen atoms become liquid-like while oxygen atoms remain solid-like on a crystalline lattice — with unprecedented resolution. Hydrogen atoms diffuse easily between the superionic …
