Microbial management

Posted by in categories: biotech/medical, health

The human colon is home to a complex microbial ecosystem (microbiota), composed mostly of anaerobic organisms. Recent data suggest that gut microbes and their metabolites can affect human health through multiple mechanisms including altering the immune response , changing host cell metabolic states , and even affecting the response to immunotherapies.

The potential causative role of gut microbiota in health and disease is one of the most extraordinary findings of the past decade. Yet we are only starting to understand the multitude of mechanisms by which microbes promote changes in intestinal physiology, and how changes in the symbiotic relationship between the host and the resident microbiota contribute to the pathogenesis of both infectious and noninfectious diseases.

Study of 17 Million Identifies Crucial Risk Factors for Coronavirus Deaths

Posted by in categories: biotech/medical, health

An analysis of more than 17 million people in England — the largest study of its kind, according to its authors — has pinpointed a bevy of factors that can raise a person’s chances of dying from COVID-19, the disease caused by the coronavirus.

The paper, published Wednesday in Nature, echoes reports from other countries that identify older people, men, racial and ethnic minorities, and those with underlying health conditions among the more vulnerable populations.

“This highlights a lot of what we already know about COVID-19,” said Uchechi Mitchell, a public health expert at the University of Illinois at Chicago who was not involved in the study. “But a lot of science is about repetition. The size of the study alone is a strength, and there is a need to continue documenting disparities.”

Episode 6 — Why Space Aliens Won’t Need Ginormous Heads

Posted by in category: alien life

We hear a lot of talk about the possibility of intelligent E.T.s, but in this episode, neuroscientist Lori Marino gives us the nuts and bolts of what intelligence really is; how it manifests itself on our own Earth; and why intelligent aliens won’t necessarily need ginormous brains.

Florida company wants to start offering balloon rides to the edge of space

Posted by in category: space travel

ANCHORAGE, Alaska — A company wants to use an advanced balloon to fly customers from Earth’s surface in Alaska to the highest reaches of the planet’s atmosphere.

Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune, The Anchorage Daily News reported Sunday.

The balloon rides will be manned by a flight crew taking eight passengers in a pressurized capsule suspended beneath a hydrogen balloon the size of a football stadium.

For The First Time, Scientists Find a Way to Make Targeted Edits to Mitochondrial DNA

Posted by in categories: biotech/medical, genetics

Most cells in your body come with two genetic libraries; one in the nucleus, and the other inside structures called mitochondria — also known as the ‘powerhouses of the cell’.

Until now, we’ve only had a way to make changes to one.

A combined effort by several research teams in the US has led to a process that could one day allow us to modify the instructions making up the cell’s ‘other’ genome, and potentially treat a range of conditions that affect how we power our bodies.

6 Dimensionality Reduction Algorithms With Python

Posted by in categories: information science, robotics/AI

Dimensionality reduction is an unsupervised learning technique.

Nevertheless, it can be used as a data transform pre-processing step for machine learning algorithms on classification and regression predictive modeling datasets with supervised learning algorithms.

There are many dimensionality reduction algorithms to choose from and no single best algorithm for all cases. Instead, it is a good idea to explore a range of dimensionality reduction algorithms and different configurations for each algorithm.
