This gut hormone could explain 40% of IBS-D cases—and lead to a cure

High levels of a hormone found in cells in the gut could underlie many cases of chronic diarrhea and help explain up to 40% of cases of patients with irritable bowel syndrome with diarrhea, according to a new study led by scientists at the University of Cambridge. The research, published…

Did humans learn to walk in trees?

It’s hard to tell when — and why — our ancestors got down from trees and started walking on two legs. Many early hominins capable of bipedal walking were also well-adapted for climbing, and we lack fossil evidence from a key period when climate change turned forests into open, dry…

Atomic-scale secrets: What really happens inside your battery

Electrochemical cells – or batteries, as a well-known example – are complex technologies that combine chemistry, physics, materials science and electronics. More than power sources for everything from smartphones to electric vehicles, they remain a strong motivation for scientific inquiry that seeks to fully understand their structure and evolution at…

Columbia scientists turn yogurt into a healing gel that mimics human tissue

Researchers from Columbia Engineering have established a framework for the design of bioactive injectable hydrogels formulated with extracellular vesicles (EVs) for tissue engineering and regenerative medicine applications. Published on July 25 in Matter, Santiago Correa, assistant professor of biomedical engineering at Columbia Engineering, and his collaborators describe an injectable hydrogel platform…

La consulta ‘alza’ il tetto agli stipendi della Pa – Notizie – Ansa.it

La Corte costituzionale boccia il tetto fisso di 240mila euro applicato ai dirigenti e ai manager pubblici dal 2014. Il limite massimo torna così ad essere parametrato al trattamento economico del primo presidente della Corte di Cassazione, che viene indicato dalla sentenza a 311.658,23, cioè all’ultimo aggiornamento fatto nel passato.…

Ghost particles may secretly decide the fate of collapsing stars

Neutrinos are cosmic tricksters, paradoxically hardly there but lethal to stars significantly more massive than the sun. These elementary particles come in three known “flavors”: electron, muon and tau. Whatever the flavor, neutrinos are notoriously slippery, and much about their properties remains mysterious. It is almost impossible to collide neutrinos…

Scientists just cracked the cryptographic code behind quantum supremacy

Experts say quantum computing is the future of computers. Unlike conventional computers, quantum computers leverage the properties of quantum physics such as superposition and interference, theoretically outperforming current equipment to an exponential degree. When a quantum computer is able to solve a problem unfeasible for current technologies, this is called…
