As earth becomes less habitable due to the climate emergency, The Astroland Agency are working out how humans could colonize Mars by 2035. Before the pandemic, we spent time with them to learn how that would work.

Particle accelerators generate high-energy beams of electrons, protons and ions for a wide range of applications, including particle colliders that shed light on nature’s subatomic components, X-ray lasers that film atoms and molecules during chemical reactions and medical devices for treating cancer.

As a rule of thumb, the longer the accelerator, the more powerful it is. Now, a team led by scientists at the Department of Energy’s SLAC National Accelerator Laboratory has invented a new type of accelerator structure that delivers a 10 times larger energy gain over a given distance than conventional ones. This could make accelerators used for a given application 10 times shorter.

The key idea behind the technology, described in a recent article in Applied Physics Letters, is to use to boost particle energies.

The cell membrane, the wall-like boundary between the cell interior and its outside environment, is primarily made up of two kinds of biomolecules: lipids and proteins. Different lipid species closely pack together to form a double layer, or “bilayer,” the membrane’s fundamental structure, while proteins are embedded within or attached to the bilayer.

Membrane proteins are responsible for various important cellular activities, and their dysfunction can lead to serious health issues. Studying protein structures and how they behave will help scientists better understand their connection to diseases and aid in developing therapeutics.

A team of researchers led by Vanderbilt University has recently shed light on how membrane proteins could be influenced by the lipids around them. By developing a novel type of membrane model, the scientists were able to show that the shape and behavior of a protein can be altered by exposure to different compositions.

WEDNESDAY, Sept. 23, 2020 (HealthDay News) — A common type 2 diabetes drug called metformin may have an unexpected, but positive, side effect: New research suggests that people taking the drug appear to have significantly slower declines in thinking and memory as they age.

“Our six-year study of older Australians with type 2 diabetes has uncovered a link between metformin use and slower cognitive [mental] decline and lower dementia rates,” said study author Dr. Katherine Samaras. She’s the leader of the healthy aging research theme at the Garvan Institute of Medical Research in New South Wales, Australia.

“The findings provide new hope for a means of reducing the risk of dementia in individuals with type 2 diabetes, and potentially those without diabetes,” Samaras said.
