Scientists Explore The Possibility Of Life Hidden Inside The Clouds Of Venus

A new study has posited the idea that microbial life could exist in Venus’s clouds.

In a new study, scientists are exploring the idea that life could be lurking high up in the clouds of Venus, and suggest that the planet’s atmosphere would be the perfect place to begin a search for microbial life.

Scientist Sanjay Limaye, who works at the University of Wisconsin–Madison’s Space Science and Engineering Center, conducted the latest research with a group of international researchers and noted that it is highly possible that Venus may have once had a plentiful supply of liquid water on the planet’s surface that could have been in existence for at least 2 billion years, according to Phys. Org.

Protein Engineering May Be the Future of Science

Scientists are increasingly betting their time and effort that the way to control the world is through proteins. Proteins are what makes life animated. They take information encoded in DNA and turn it into intricate three-dimensional structures, many of which act as tiny machines. Proteins work to ferry oxygen through the bloodstream, extract energy from food, fire neurons, and attack invaders. One can think of DNA as working in the service of the proteins, carrying the information on how, when and in what quantities to make them.

Living things make thousands of different proteins, but soon there could be many more, as scientists are starting to learn to design new ones from scratch with specific purposes in mind. Some are looking to design new proteins for drugs and vaccines, while others are seeking cleaner catalysts for the chemical industry and new materials.

David Baker, director for the Institute for Protein Design at the University of Washington, compares protein design to the advent of custom tool-making. At some point, proto-humans went beyond merely finding uses for pieces of wood, rock or bone, and started designing tools to suit specific needs — from screwdrivers to sports cars.

Biological Cells Fused with Artificial Cells

For the first time in history, researchers have fused artificial cells with biological cells in a way that lets them work together. This opens the door for a variety of new possibilities and applications.

Fusing biological and artificial cells

The research team at Imperial College London uses a system that encapsulates biological cells within an artificial cell. Using this approach, the team can harness the ability of biological cells to produce chemicals while offering them protection from the environment.

Bionic Kidney To Replace Dialysis

It’s not uncommon for the press to get hyped up before the long process of refinement and FDA approval. Let’s hope that this one moves along quickly — while demonstrating safety and efficacy.

Hybrid artificial-natural cells bring together the best of both worlds

Sometimes I think I’m jumping the gun when speculating. Take this further, a better full body replacement?

The more we study natural biological cells, the more we learn about how to control them or build artificial versions. These independent avenues of study have huge potential, but also their limitations. Researchers from Imperial College London have worked out a way to borrow the strengths of each, fusing together living and non-living cells to create tiny chemical factories that might one day aid drug delivery.

In past work, scientists have packaged proteins and enzymes inside artificial casings to better treat conditions like cancer or diabetes. Rather than just using some natural parts, the Imperial College study instead wrapped entire biological cells inside artificial ones.

“Biological cells can perform extremely complex functions, but can be difficult to control when trying to harness one aspect,” says Oscar Ces, lead researcher on the project. “Artificial cells can be programmed more easily but we cannot yet build in much complexity. Our new system bridges the gap between these two approaches by fusing whole biological cells with artificial ones, so that the machinery of both works in concert to produce what we need.”
