Method identified to double computer processing speeds

Science Daily: Pharmacology News

Scientists introduce what they call 'simultaneous and heterogeneous multithreading' or SHMT. This system doubles computer processing speeds with existing hardware by simultaneously using graphics processing units (GPUs), hardware accelerators for artificial intelligence (AI) and machine learning (ML), or digital signal processing units to process information.

Weight Loss Drugs arent “the answer”

Sheffield DPH

This one is a working note style. More so than normal:) my working list of why weight loss drugs aren’t the ansa (sorry not terribly well organised) is below. Before you read this, you must read Phil’s New Statesman article on GLP1 agonists. 1. cost. current list price, the annual cost of treatment would be £2275 + clinical time. Opportunity cost ??

Baleen whales evolved a unique larynx to communicate but cannot escape human noise

Science Daily: Pharmacology News

The iconic baleen whales, such as the blue, gray and humpback whale, depend on sound for communication in the vast marine environment where they live. Now researchers have for the first time found that baleen whales evolved novel structures in their larynx to make their vast array of underwater songs.

New water batteries stay cool under pressure

Science Daily: Pharmacology News

A global team of researchers has invented recyclable 'water batteries' that won't catch fire or explode. The team use water to replace organic electrolytes -- which enable the flow of electric current between the positive and negative terminals -- meaning their batteries can't start a fire or blow up -- unlike their lithium-ion counterparts.

Black hole at center of the Milky Way resembles a football

Science Daily: Pharmacology News

The supermassive black hole in the center of the Milky Way is spinning so quickly it is warping the spacetime surrounding it into a shape that can look like a football, according to a new study. That football shape suggests the black hole is spinning at a substantial speed, which researchers estimated to be about 60% of its potential limit.

Toxic elements found in stranded whales, dolphins over 15 years

Science Daily: Pharmacology News

Researchers evaluated the prevalence, concentration and tissue distribution of essential and non-essential trace elements, including heavy metal toxicants in tissue (blubber, kidney, liver, skeletal muscle, skin) and fecal samples collected from 90 whales and dolphins stranded in Georgia and Florida from 2007 to 2021.

Did neanderthals use glue? Researchers find evidence that sticks

Science Daily: Pharmacology News

Neanderthals created stone tools held together by a multi-component adhesive, a team of scientists has discovered. Its findings, which are the earliest evidence of a complex adhesive in Europe, suggest these predecessors to modern humans had a higher level of cognition and cultural development than previously thought.

Researchers develop molecules for a new class of antibiotics that can overcome drug resistant bacteria

Science Daily: Pharmacology News

About a decade ago, researchers began to observe a recurring challenge in their research: Some of the compounds they were developing to harness energy from bacteria were instead killing the microbes. Not good if the objective of the project was to harness the metabolism of living bacteria to produce electricity.

Revealing what makes bacteria life-threatening

Science Daily: Pharmacology News

Researchers have discovered that a mutation in the cellulose making machinery of E. coli bacteria allows them to cause severe disease in people -- 'good' bacteria make cellulose and 'bad' bacteria can't. The mutations stopped the E. coli making the cell-surface carbohydrate cellulose and this led to increased inflammation in the intestinal tract of the host, resulting in a breakdown of the intestinal barrier, so the bacteria could spread through the body.

An awkward family reunion: Sea monsters are our cousins

Science Daily: Pharmacology News

The sea lamprey, a 500-million-year-old animal with a sharp-toothed suction cup for a mouth, is the thing of nightmares. A new study discovered that the hindbrain -- the part of the brain controlling vital functions like blood pressure and heart rate -- of both sea lampreys and humans is built using an extraordinarily similar molecular and genetic toolkit.

Little groundwater recharge in ancient Mars aquifer, according to new models

Science Daily: Pharmacology News

Mars was once a wet world. The geological record of the Red Planet shows evidence for water flowing on the surface -- from river deltas to valleys carved by massive flash floods. But a new study shows that no matter how much rainfall fell on the surface of ancient Mars, very little of it seeped into an aquifer in the planet's southern highlands.

Engineers use AI to wrangle fusion power for the grid

Science Daily: Pharmacology News

A team composed of engineers, physicists, and data scientists have harnessed the power of artificial intelligence to predict -- and then avoid -- the formation of a specific plasma problem in real time. The research opens the door for more dynamic control of a fusion reaction than current approaches and provides a foundation for using artificial intelligence to solve a broad range of plasma instabilities, which have long been obstacles to achieving a sustained fusion reaction.

High resolution techniques reveal clues in 3.5 billion-year-old biomass

To learn about the first organisms on our planet, researchers have to analyze the rocks of the early Earth. These can only be found in a few places on the surface of the Earth. The Pilbara Craton in Western Australia is one of these rare sites: there are rocks there that are around 3.5 billion years old containing traces of the microorganisms that lived at that time.
