Get on the waitlist for the Atom Touch.
Atom Touch is a revolutionary Prosthetic Bionic Arm.
An international team which includes University of Manchester scientists has for the first time demonstrated that nerve signals are exchanged between clogged up arteries and the brain.
The discovery of the previously unknown electrical circuit is a breakthrough in our understanding of atherosclerosis, a potentially deadly disease where plaques form on the innermost layer of arteries.
The study of mice found that new nerve bundles are formed on the outer layer of where the artery is diseased, so the brain can detect where the damage is and communicate with it.
According to a new theory by LMU chemists led by Thomas Carell, it was a novel molecular species composed of RNA
Ribonucleic acid (RNA) is a polymeric molecule similar to DNA that is essential in various biological roles in coding, decoding, regulation and expression of genes. Both are nucleic acids, but unlike DNA, RNA is single-stranded. An RNA strand has a backbone made of alternating sugar (ribose) and phosphate groups. Attached to each sugar is one of four bases—adenine (A), uracil (U), cytosine ©, or guanine (G). Different types of RNA exist in the cell: messenger RNA (mRNA), ribosomal RNA (rRNA), and transfer RNA (tRNA).
The latest COVID-19 variant – dubbed BA.2.12.1 – has been linked to 43% of total coronavirus cases in the U.S., a jump from 7% in April.
And, as more data about the variant becomes known, a pattern in early symptoms is emerging. BA.2.12.1 is a descendant of the BA.2 virus, a subvariant of the omicron strain of COVID. It has the ability transmit easier than its predecessors and expect it to become the dominant strain of COVID-19 within a few weeks.
Like previous COVID omicron strains, BA.2.12.1 often presents with upper respiratory symptoms that can appear like the flu. Experts said BA.2.12.1 is triggering mild breakthrough cases in vaccinated individuals with people feeling like they are suffering from a cold or seasonal allergies.
A team of researchers led by Yale University.
Established in 1,701, Yale University is a private Ivy League research university in New Haven, Connecticut. It is the third-oldest institution of higher education in the United States and is organized into fourteen constituent schools: the original undergraduate college, the Yale Graduate School of Arts and Sciences and twelve professional schools. It is named after British East India Company governor Elihu Yale.
“This new study joins a growing body of scientific evidence that raises questions about the irreversible nature of death…”
Scientists have revived light-sensing neuron cells in organ donor eyes and restored communication between them as part of a series of discoveries that could transform research into the brain-vision system.
The Facility for Rare Isotope Beams opens its doors to experiments that will study the formation of heavy elements in the Universe and provide critical tests of nuclear theories.
The nuclear physics community is hailing the kickoff of a long-awaited facility for producing beams of radioactive isotopes, with a cohort of users gearing up for the first experiments. The Facility for Rare Isotope Beams (FRIB) at Michigan State University opens its doors to experimenters this week. FRIB is expected to deliver the widest range of rare isotopes of any existing facility, including many never-before-synthesized isotopes. The facility will also allow researchers to control the energies of the isotope beams so that they match those relevant to nuclear processes in stars and supernovae.
Rare isotopes get their name from their scarcity—these unstable nuclei decay radioactively and thus cannot be found naturally on Earth. But making sizable quantities of these elements in a lab will allow scientists to tackle important open problems in physics. Current nuclear theories, for instance, can’t describe many nuclei, and rare isotopes provide extreme cases on which to test why such theories fail. Rare isotopes are also relevant to the cosmic nucleosynthesis of heavy elements, a process for which there isn’t yet a satisfactory explanation. On the applied side, radioactive isotopes can be useful for medical imaging, cancer treatment, and other industrial applications.
Summary: Supplementing a diet with Ascidiacea, or sea squirts, reversed some of the main signs of aging in mouse models.

If you have ever looked in the mirror and seen graying hair and wrinkles or forgotten the name of a close friend, you’d be forgiven for wishing for a pill that could slow or even reverse the effects of aging.
Gene editing reverses brain genetic reprogramming caused by adolescent binge drinking.
Gene editing may be a potential treatment for anxiety and alcohol use disorder in adults who were exposed to binge drinking in their adolescence, according to the findings of an animal study published on May 4, 2022, in the journal Science Advances.
The study was issued by researchers from the University of Illinois Chicago (UIC) who have been studying the effects of early-life binge drinking on health later in life.
