Long-standing mystery in membrane traffic solved

In 2013, James E. Rothman, Randy W. Schekman, and Thomas C. Südhof won the Nobel Prize in Physiology or Medicine for their discoveries of molecular machineries for vesicle trafficking, a major transport system in cells for maintaining cellular processes. Show More Summary

These Shapeshifting DNA Nanostructures Move Like Tiny Machines

The cells that make up your body are filled with amazing molecular machinery, honed by evolution to perform the tiny biological tasks that keep youalive. There are motor molecules that scoot along the protein skeletons that give your...Show More Summary

First-in-Human Results for New Handheld Autofluorescence Imaging Platform: Real-Time Sampling and Treatment Guidance of Chronic Wound Infections

We previously reported on PRODIGI, a handheld autofluorescence imaging platform for real-time detection and tracking of bacterial infections in wounds. Canadian molecular imaging scientist Dr. Ralph DaCosta and colleagues at the Princess...Show More Summary

The Starmaker --Fierce Colossal Winds of a Galaxy's Supermassive Black Hole

Star formation takes place in cold, dense molecular clouds. By heating and dispersing gas that could one day make stars, the black-hole wind forever alters a large portion of its galaxy. By combining observations from the Japan-led Suzaku X-ray satellite...

The first observation of the effect of electron spin of molecular oxygen on the surface oxidation reaction

Scientists have presented the first spin-controlled oxygen adsorption experiment indicating that the rate of surface oxidation is strongly affected by the electron spin of oxygen. 

Chemical Tag Marks Future Micrornas for Processing, Study Shows

Just as two DNA strands naturally arrange themselves into a helix, DNA's molecular cousin RNA can form hairpin-like loops. But unlike DNA, which has a single job, RNA can play many parts -- including acting as a precursor for small molecules that block the activity of genes. Show More Summary

An Introduction to "Molecular Cocktology"

What’s the next step in cocktail evolution? Call it “molecular cocktology” and its engines – Buchi rotavapors, refractometers and immersion circulators. Read the rest of the story at: An Introduction to "Molecular Cocktology"

Four-stranded DNA-binding protein conserved in plants and animals

Molecular biophysicists show that the same type of protein works in plants and animals to bind to peculiar DNA structures called G-quadruplexes, or G4 DNA for short.

Heart Attack That Strikes Young Women May Run In The Family

4 days agoNews : Huffington Post

By Sharon Begley NEW YORK, March 23 (Reuters) - Although oncologists increasingly distinguish breast, lung, and other cancers by their molecular drivers, cardiologists have lagged behind in efforts to do something similar for heart disease. A...Show More Summary

This Bad-Boy Geneticist Wants to Clone a Mammoth

Hwang Woo-Suk, the disgraced molecular biologist, is trying to clone a mammoth. But his plan was probably foiled 30,000 years ago by cosmic radiation. The post This Bad-Boy Geneticist Wants to Clone a Mammoth appeared first on WIRED...

Beliefs About Brilliance and the Demography of Academic Fields

A new study led by philosopher Sarah-Jane Leslie challenges the idea that women are underrepresented in STEM fields. They first note that there are some STEM fields where women do well (they are 54% of molecular biologists, for example) and some humanities fields where they don’t (they are only 31% of philosophers). Something else, they […]

Even at a molecular level, taking it slow helps us cope with stress

A new molecular pathway critical to aging has been discovered by scientists. They found that by slowing down the activity of mitochondria in the blood stem cells of mice, they could enhance the cells' capacity to handle stress and rejuvenate old blood.

Rosetta Probe Reveals Key Molecule from Early Nebula Origin of Solar System

A's comet probe Rosetta has for the first time ever measured nitrogen gas at a comet, providing clues to the early stages of the formation of our solar system. Molecular nitrogen, N2, is the major molecule in the atmosphere of...

Recent adaptive evolution to resist the toxic effects of arsenic

A new paper in Molecular Biology and Evolution provides an interesting new example of recent adaptation in a human population. Carina Schlebusch and colleagues examined the genetics of a group living in the Andes of northern Argentina, with a high load of arsenic in their environment. Show More Summary

Molecular Nitrogen On Rosetta Points To tThe Comet's Frigid Origins

last weekGenres / Sci Fi : io9

For the first time ever, scientists have detected molecular nitrogen on a comet. The discovery is sheds light on the nature of the pre-Solar System environment in which Comet 67P/C-G formed. Read more...

Changes in a Blood-Based Molecular Pathway Identified in Alzheimer's Disease

New research identifies a bridge between the mechanisms that spur the destruction of neurons in Alzheimer's disease - accumulation of the amyloid-? peptide (the main component of plaques found in Alzheimer's patient brains) and chronic inflammation..

Scientists must reduce antibiotic use in experiments

Scientists should reduce antibiotic use in lab experiments. According to a new article, molecular biology and genetic research such as the Human Genome Project use antibiotics in experiments. But it all adds to the global problem of antibiotic resistance according to the author.

Scientists must reduce antibiotic use in experiments

Scientists should reduce antibiotic use in lab experiments - according to a researcher at the University of East Anglia. Microbiology, molecular biology and genetic research such as the Human Genome Project use antibiotics in experiments. But...Show More Summary

Amazing Luminous Star Cluster Inside a Supernova in a Tiny Dwarf Galaxy

More than a million young stars are forming in a hot, dusty cloud of molecular gases in a tiny galaxy near our own, an international team of astronomers has discovered. The star cluster is buried within a supernebula in a...

How planthoppers got (and changed) their wings

Each year, rice faces a big threat from a sesame seed-sized insect called the brown planthopper. Now, a study reveals the molecular switch that enables some planthoppers to develop short wings and others long based on environmental conditions such as day length and temperature -- a major factor in their ability to invade new rice fields.
