Team creates synthetic enzymes to unravel molecular mysteries      (via sciencedaily.com)     Original source 

A bioengineer has developed synthetic enzymes that can control the behavior of the signaling protein Vg1, which plays a key role in the development of muscle, bone and blood in vertebrate embryos. The team of researchers is using a new approach, called the Synthetic Processing (SynPro) system, in zebrafish to study how Vg1 is formed. By learning the molecular rules of signal formation in a developing animal, researchers aim to engineer mechanisms -- such as giving cells new instructions -- that could play a role in treating or preventing disease.

How human faces can teach androids to smile      (via sciencedaily.com)     Original source 

A research team used 125 physical markers to understand the detailed mechanics of 44 different human facial motions. The aim was to better understand how to convey emotions with artificial faces. Beyond helping with the design of robots and androids, this research can also benefit computer graphics, facial recognition, and medical diagnoses.

First live birth of a chimeric monkey using embryonic stem cell lines      (via sciencedaily.com)     Original source 

A team of researchers has reported for the first time the live birth of a monkey that contains a high proportion of cells derived from a monkey stem cell line. This 'chimeric' monkey is composed of cells that originate from two genetically distinct embryos of the same species of monkey. This has previously been demonstrated in rats and mice but, until now, has not been possible in other species, including non-human primates.

Zen and the art of mitochondrial maintenance: The machinery of death makes a healthier life      (via sciencedaily.com)     Original source 

While we all aspire for a long lifespan, what is most coveted is a long period of vigor and health, or 'healthspan,' that precedes the inevitable decline of advancing age. Researchers have discovered that instruments of death that cells use to commit suicide when things go wrong contribute to making a longer and healthier life by revitalizing the specialized cellular compartments called mitochondria.

Yeast with an over half synthetic genome is created in the lab      (via sciencedaily.com)     Original source 

Researchers have combined over seven synthetic chromosomes that were made in the lab into a single yeast cell, resulting in a strain with more than 50% synthetic DNA that survives and replicates similarly to wild yeast strains. A global consortium is working to develop the first synthetic eukaryote genome from scratch. The team has now synthesized and debugged all sixteen yeast chromosomes.

Scientists take major step towards completing the world's first synthetic yeast      (via sciencedaily.com)     Original source 

A team of Scientists has completed construction of a synthetic chromosome as part of a major international project to build the world's first synthetic yeast genome. The work represents completion of one of the 16 chromosomes of the yeast genome, which is part of the biggest project ever in synthetic biology; the international synthetic yeast genome collaboration. The collaboration, known as 'Sc2.0' has been a 15-year project involving teams from around the world (UK, US, China, Singapore, UK, France and Australia), working together to make synthetic versions of all of yeast's chromosomes. Alongside this paper, another 9 publications are also released today from other teams describing their synthetic chromosomes. The final completion of the genome project -- the largest synthetic genome ever -- is expected next year.

Obesity linked to neurodegeneration through insulin resistance      (via sciencedaily.com)     Original source 

Researchers have discovered a link between obesity and neurodegenerative disorders like Alzheimer's disease. Using the common fruit fly, the research shows that a high-sugar diet -- a hallmark of obesity -- causes insulin resistance in the brain, which in turn reduces the ability to remove neuronal debris, thus increasing the risk of neurodegeneration.

Video technology could transform how scientists monitor changes in species evolution and development      (via sciencedaily.com)     Original source 

New research combines microscope and video technology to analyze how different species develop, and how changes in the timings of any developments can be tracked. A detailed analysis of the Energy Proxy Traits (EPTs) that result from these processes has provided researchers with the first evidence that traditionally measured timings of developmental events are associated with far broader changes to the full set of an embryo's observable characteristics.

Researchers develop solid-state thermal transistor for better heat management      (via sciencedaily.com)     Original source 

A team of researchers has unveiled a first-of-its-kind stable and fully solid-state thermal transistor that uses an electric field to control a semiconductor device's heat movement.  The group's study details how the device works and its potential applications. With top speed and performance, the transistor could open new frontiers in heat management of computer chips through an atomic-level design and molecular engineering. The advance could also further the understanding of how heat is regulated in the human body.
