Single laser stops molecular tumbling motion instantly

In the quantum world, making the simple atom behave is one thing, but making the more complex molecule behave is another story. Now Northwestern University scientists have figured out an elegant way to stop a molecule from tumbling so...Show More Summary

Discovery hints at why stress is more devastating for some

Some people take stress in stride; others are done in by it. New research at Rockefeller University has identified the molecular mechanisms of this so-called stress gap in mice with very similar genetic backgrounds — a finding that could lead researchers to better understand the development of psychiatric disorders such as anxiety and depression. read more

Nanoscale Assembly Line Created

ScienceDaily: Cars, planes and many electronic products are now built with the help of sophisticated assembly lines. The creation of such an assembly line at molecular level has been a long-held dream of many nanoscientists. "It would...Show More Summary

Why sibling stars look alike: Early, fast mixing in star-birth clouds

Early, fast, turbulent mixing of gas within giant molecular clouds -- the birthplaces of stars -- means all stars formed from a single cloud bear the same unique chemical 'tag' or 'DNA fingerprint,' write astrophysicists. Could such chemical tags help astronomers identify our own Sun's long-lost sibling stars?

Precision control of the timing, structure and functions in molecular self-assembly

Scientists have developed a new methodology that can easily and precisely control the timing of and the structure as well as functions obtained in self-assembly of ?-conjugated molecules, which is a key technology in the field of organic electronics materials.

Vast Streams of Gravel Detected in Orion Molecular Cloud -- "A Long and Winding Road in Space Essential for Planet Formation"

Astronomers using the National Science Foundation’s (NSF) Green Bank Telescope (GBT) have discovered that filaments of star-forming gas near the Orion Nebula may be brimming with pebble-size particles -- planetary building blocks 100 to 1,000 times larger than the dust...

Novel 'butterfly' molecule could build new sensors, photoenergy conversion devices

Exciting new work has led to a novel molecular system that can take your temperature, emit white light, and convert photon energy directly to mechanical motions. And, the molecule looks like a butterfly.

Novel 'butterfly' molecule could build new sensors, photoenergy conversion devices

TALLAHASSEE, Fla. — Exciting new work by a Florida State University research team has led to a novel molecular system that can take your temperature, emit white light, and convert photon energy directly to mechanical motions. And, the...Show More Summary

Promising new cancer therapy uses molecular 'Trash Man' to exploit a common cancer defense

While many scientists are trying to prevent the onset of a cancer defense mechanism known as autophagy, other researchers are leveraging it in a new therapy that causes the process to culminate in cell death rather than survival.

Evolution used similar molecular toolkits to shape flies, worms, and humans

Although separated by hundreds of millions of years of evolution, flies, worms, and humans share ancient patterns of gene expression, according to a massive Yale-led analysis of genomic data. Two related studies led by scientists at Harvard and Stanford, also published Aug. Show More Summary

The Smallest Drugs

Here is the updated version of the "smallest drugs" collection that I did the other day. Here are the criteria I used: the molecular weight cutoff was set, arbitrarily, at aspirin's 180. I excluded the inhaled anaesthetics, only allowing things that are oils or solids in their form of use. Show More Summary

GenMark Diagnostics Hoping To Make Its Mark In Clinical MDx

By Stephen Simpson, CFA: Molecular diagnostics is still a relatively new opportunity in the clinical diagnostics space - about $4 billion/year if Roche's (OTCQX:RHHBY) estimates of its market share are accurate. It remains a good growth...Show More Summary

StartX And QB3 Open A Biotech Lab In Palo Alto

StartX, the nonprofit accelerator program spun out of Stanford University, is opening a biotech laboratory in conjunction with QB3, the institute focused on molecular biology research at the University of California. The space is intended...Show More Summary

New tool to probe cancer's molecular make-up

Scientists have shown how to better identify and measure vital molecules that control cell behaviour – paving the way for improved tools for diagnosis, prediction and monitoring of cancer. Researchers from the Cancer Research UK Manchester...Show More Summary

Characterization of the Antarctic sea urchin (Sterechinus neumayeri) transcriptome and mitogenome: a molecular resource for phylogenetics, ecophysiology and global change biology

This is the first de novo transcriptome and complete mitochondrial genome of an Antarctic sea urchin species sequenced to date. Sterechinus neumayeri is an Antarctic sea urchin and a model species for ecology, development, physiology, and global change biology. Show More Summary

Being overweight causes hazardous inflammations

A possible molecular explanation for why overweight is harmful has been discovered by researchers. They suggest that overeating increases the immune response. This increased immune response causes the body to generate excessive inflammation, which may lead to a number of chronic diseases. Show More Summary

New biomarker highly promising for predicting breast cancer outcomes

A protein named p66ShcA shows promise as a biomarker to identify breast cancers with poor prognoses, according to research published ahead of print in the journal Molecular and Cellular Biology. Cancer is deadly in large part due to its ability to metastasize, to travel from one organ or tissue type to another and malignantly sprout anew. Show More Summary
