Cellular Respiration: An Alternate Version Of The Famous Krebs Cycle?

Mar 12 2022 - 12:03
The Krebs cycle is named after Hans Krebs, who discovered it in 1937, part of the race to discover the central hub of cellular metabolism. In a cell’s mitochondria, it is a core part of the process by which cells “burn” sugars to make adenosine triphosphate (ATP), the cell’s energy-carrying molecule.

Active Matter: The Next Generation Of Robots Could Be Shape Shifters

Mar 11 2022 - 15:03
By coating soft robots in materials that allow them to move and function in a more purposeful way, scientists could design machines with arms made of flexible materials and robots embedded in their surface.

Coating the surface of nanoparticles in a responsive, active material could mean tailoring the size and shape of drug delivery capsules and have a dramatic effect on how a drug interacts with cells in the body. This ‘active matter’ could mark a turning point in the design of robots and make it possible to determine the shape, movement and behavior of a soft solid not by its natural elasticity but by human-controlled activity on its surface.

Cancel Culture In Science?

Mar 11 2022 - 13:03
Like the vast majority of readers of this column, I very strongly condemn the Russian invasion of Ukraine and the ensuing atrocities. War is never an answer to international controversies. And I would like to add: I am in favor of all sanctions that financially hit the aggressor, including cutting Russia from use of international banking circuits and similar impactful actions.

That said, I will say here what I think about this ongoing rush to find ways to hurt a country whose citizens are largely innocent of their leader's crimes. I think most of these creative initiatives are counter-productive, reaching the nonsensical, the irrational, and the plain nuts.

Transition From Hunter-Gatherer To Agriculture: Population Replacement Or Culture Change?

Mar 09 2022 - 14:03
The transition from hunter-gatherers to farmers and ranchers remains a subject of debate. In Europe, where that happened thousands of years ago, based largely on genetic studies, the prevailing view is that the "Neolithic transition" occurred mainly by population replacement rather than cultural change.

The old stuck to old ways, much like organic farmers and believers in alternative medicine do, while the young embraced progress as the elders died off.

Syllipsimopodi Bideni: An Octopus With 10 Arms Pushes Back The Age Of Vampyropoda By Nearly 82 Million Years

Mar 09 2022 - 12:03
A recent study describes a new species of vampyropod based on a 328-million-year-old fossil and pushes back the age of the group by nearly 82 million years. And shows that the oldest ancestors of the group of animals that includes octopuses and vampire squids had not eight but 10 arms. 

Vampyropods are soft-bodied cephalopods typically characterized by eight arms and an internalized chitinous shell or fin supports. Because they lack hard structures, Vampyropoda are not well represented in the fossil record. The new study is based on a vampyropod fossil from the collections of the Royal Ontario Museum. It was originally discovered in Montana and donated to the museum in 1988.

Biologic From Reengineered Human Skin Cells As COVID-19 Therapy

Mar 09 2022 - 11:03
Few treatments exist for COVID-19 and the ones that do primarily focus solely on preventing the virus from replicating.

A new potential treatment inhibits replication but also protects or repairs tissue, which is important because COVID-19 can cause symptoms that affect patients long after the viral infection has been cleared. It is a biologic substance created by reengineered human skin cells called dermal fibroblasts.
