Too much mTOR is Linked to Diabetes and Aging

Posted by in categories: biotech/medical, life extension

A new study takes a look at the relationship between metabolism, aging, and type 2 diabetes and in particular the mTORC1 protein complex, part of the mTOR pathway.

The mTOR pathway

The mechanistic target of rapamycin (mTOR) pathway is a major part of metabolism and is one of four major pathways that control it; collectively, the four pathways are part of deregulated nutrient sensing, which is one of the aging processes.

Scouting out bacterial defences to find new ways to counter-attack antibiotic resistance

Posted by in categories: biotech/medical, health

Research led by the University of Bristol has begun to unpick an important mechanism of antibiotic resistance and suggest approaches to block this resistance.

Antibiotic resistance is the ability of bacteria to defend against antibiotic attack, and the spread of these resistance mechanisms amongst bacteria is a global public health concern. A form of resistance caused by a family of bacterial proteins, the Verona Imipenemase (VIM) beta-lactamases, is of acute clinical concern because it can inactivate (penicillins and related agents) that comprise over half of the global antibacterial market.

A team of researchers led by the University of Bristol have uncovered near-atomic level structural detail of VIM proteins. The research is published today [Thursday 15 November] in The FEBS Journal.

How algae could sustainably reduce the carbon dioxide concentration in the atmosphere

Posted by in categories: climatology, sustainability

In collaboration with fellow researchers, chemists at the Technical University of Munich (TUM) have developed a process that, according to initial calculations, can facilitate economically removing the greenhouse gas carbon dioxide from the atmosphere. The latest World Climate Report (IPCC Special Report on Global Warming of 1.5 ° C) acknowledges the global relevance of the process.

Lost Continents Beneath Antarctica Unveiled in Dead Satellite’s Data

Posted by in category: energy

Ancient continents were found under Antarctic ice, thanks to old data from a now-dead European satellite.

New analysis of data from the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE) mission has revealed rocky zones called “cratons” in the Earth’s lithosphere, a zone between our planet’s crust and mantle. GOCE plunged into Earth’s atmosphere five years ago this month after the craft ran out of orbital-maneuvering fuel. While scientists were unable to predict exactly where GOCE would fall, no debris dropped into populated areas.

China’s “Artificial Sun” Is Now Hot Enough for Nuclear Fusion

Posted by in categories: nuclear energy, space

Tokamaks like EAST could help us do just that. They’re devices that use magnetic fields to control plasma in a way that could support stable nuclear fusion, and it’s this plasma that EAST heated to such an incredible temperature.

Going Nuclear

Not only is EAST’s new plasma temperature milestone remarkable because, wow, it’s really hot, it’s also the minimum temperature scientists believe is needed to produce a self-sustaining nuclear fusion reaction on Earth.
