Study finds potential new target to treat asthma attacks brought on by colds

Researchers have identified a molecular mechanism that could explain why the common cold can bring on life-threatening asthma attacks. Published today in Science Translational Medicine, the findings indicate this may be a potential target...Show More Summary

Wonderful combination of science and design

yesterdayOdd : Kottke.org

Eleanor Lutz has a degree in molecular biology, works as a designer, and loves to combine the two interests by making these wonderful information graphics on her site, Tabletop Whale. Her most recent post is an animated graphic showing...Show More Summary

Stressed out: Research sheds new light on why rechargeable batteries fail

Pity the poor lithium ion. Drawn relentlessly by its electrical charge, it surges from anode to cathode and back again, shouldering its way through an elaborate molecular obstacle course. This journey is essential to powering everything from cell phones to cordless power tools. Show More Summary

Deconstruction of avant-garde cuisine could lead to even more fanciful dishes

One of the most iconic forms of avant-garde cuisine, also known as molecular gastronomy, involves the presentation of flavorful, edible liquids — like cocktails or olive oil — packaged into spheres. Now a team of scientists, in collaboration...Show More Summary

First mapping that reveals the molecular pathway for MDSC cancer progression

Scientists from InSilico Medicine and its partners successfully established a visual mapping of the molecular pathway cancer progression originating from myeloid derived suppressor cells (MDSC). The damage and immune suppression the cells cause are not fully understood, however this is a major stepping stone in creating necessary transparency. Show More Summary

Experts from CNIO discover shining cells responsible for developing tumors

Tumours are mosaics of cells that are morphologically and molecularly very different. In this cellular heterogeneity, it is calculated that only 1-2% of the tumour mass is made up of cancer stem cells, which over the past years have been suggested to be responsible for the origin of cancer and for the resistance to conventional chemical therapies.

Complex Organic Molecules Found in Giant Gas Cloud Near Milky Way’s Galactic Center

Hunting from a distance of 27,000 light years, astronomers have discovered an unusual carbon-based molecule – one with a branched structure – contained within a giant gas cloud in interstellar space. Like finding a molecular needle in a cosmic haystack,...

30% to 50% of Earth's Water Today came from the Primordial Molecular Cloud --"Older than the Solar System Itself"

Up to half of the water on Earth is likely older than the solar system itself, University of Michigan astronomers theorize. The researchers' work helps to settle a debate about just how far back in galactic history our planet and...

A molecular mechanism involved in cellular proliferation characterized

Researchers from Guillermo Montoya's team at the Spanish National Cancer Research Centre (CNIO), in collaboration with Isabelle Vernos' Group from the Centre for Genomic Regulation (CRG), have uncovered the molecular interaction between TACC3 and chTOG, key proteins in forming the internal cellular framework that enables and sustains cell division.

Unexpected clue to peripheral neuropathies found

Disrupting the molecular function of a tumor suppressor causes improper formation of a protective insulating sheath on peripheral nerves -- leading to neuropathy and muscle wasting in mice similar to that in human diabetes and neurodegeneration. A new study also suggests that normal molecular function of the tumor suppressor gene Lkb1 is essential to the formation process.

New molecule found in space connotes life origins

Hunting from a distance of 27,000 light years, astronomers have discovered an unusual carbon-based molecule – one with a branched structure – contained within a giant gas cloud in interstellar space. Like finding a molecular needle in a cosmic haystack, astronomers have detected radio waves emitted by isopropyl cyanide. Show More Summary

MIT Scientists Create Greener, Stronger Concrete With Half the CO2 Emissions

MIT researchers may have found a way to produce “greener” cement, the emissions of which, compared to the commonly used mixture, would be reduced by more than half! Through detailed molecular analysis of the structure of concrete, the team has reached

Study identifies unexpected clue to peripheral neuropathies

CINCINNATI – New research shows that disrupting the molecular function of a tumor suppressor causes improper formation of a protective insulating sheath on peripheral nerves – leading to neuropathy and muscle wasting in mice similar to that in human diabetes and neurodegeneration. read more

Unlocking long-hidden mechanisms of plant cell division

Along with copying and splitting DNA during division, cells must have a way to break safely into two viable daughter cells, a process called cytokinesis. But the molecular basis of how plant cells accomplish this without mistakes has been unclear for many years. Show More Summary

'Funnel' attracts bonding partners to biomolecule

Valeria Conti Nibali and Prof Dr Martina Havenith-Newen (Cluster of Excellence RESOLV – Ruhr explores Solvation) made this discovery by using a combination of terahertz absorption spectroscopy and molecular dynamics simulations. The researchers report their findings in the Journal of the American Chemical Society (JACS). Choreography of water movements read more

Molecular Chainmaille Could Be The Lightest and Strongest Armor Ever

Chainmaille, for the most part, exists in only two forms in modern society: as geeky jewelry made in college dorm rooms and as an entry on an RPG character sheet. The main reason for this is…

Genetic switch regulates a plant's internal clock based on temperature

Scientists have found the molecular cog in a plant's biological clock that modulates its speed based on temperature. "Temperature helps keep the hands of the biological clock in the right place," said the corresponding author of the study. "Now we know more about how that works."

Genetic switch regulates a plant's internal clock based on temperature

Scientists have discovered a key molecular cog in a plant's biological clock – one that modulates the speed of circadian (daily) rhythms based on temperature. Transcription factors, or genetic switches, drive gene expression in plants based on external stresses – such as light, rain, soil quality, or even animals grazing on them. Show More Summary

Scientists create a ‘Star of David’ molecule — a step towards molecular chainmail

last weekHealth : The Checkup

Scientists at the University of Manchester have created a new molecular shape -- a group of interlocking rings, twisted into a six-pointed "Star of David." But they weren't inspired by the shape's religious symbolism: The molecule, reported Sunday in Nature Chemistry, is the most complex molecular shape ever created in the lab. Read full article >>

The accelerator of molecular motors

To their surprise, it turned out to be an old acquaintance: a certain module of the familiar protein Pex22p, which has hitherto always been considered an anchor protein. The researchers report their findings in PLoS One. Essential: importing enzymes into peroxisome read more
