When life on Earth began nearly 4 billion years ago, long before humans, dinosaurs or even the earliest single-celled forms of life roamed, it may have started as a hiccup rather than a roar: small, simple molecular building blocks known...
Whether you're a human, a mouse, or even a fruitfly, losing sleep is a bad thing, leading to physiological effects and behavioral changes. Researchers used fruitflies to probe deeper into the cellular and molecular mechanisms that govern...Show More Summary
For the first time, researchers have directly seen how organic molecules bind to other materials at the atomic level. Using a special kind of electron microscopy, this information can lead to increasing the life span of electronic devices, for example.
Up until recently there was a single known species in the only vertebrate family endemic to West Africa, the torrent tooth-frog. Based on morphological and molecular results, however, four new species are now described. Unfortunately, they might all be at a risk of extinction. Their habitat needs and small distribution range call for immediate conservation measures.
Scientists have unraveled how an important plant protein, known as TOPLESS, interacts with other molecules responsible for turning genes off. The findings in plants provide a general model across species for this type of gene silencing, which is linked to several vital biological functions in humans.
Pathogenic bacteria develop killer machines that work very specifically and highly efficiently. Scientists have solved the molecular mechanism of a fish toxin that could be used in the future as a medication to treat cancer.
A group of researchers from the Lomonosov Moscow State University tried to address one of the least understood issues in the modern molecular biology, namely, how do strands of DNA pack themselves into the cell nucleus. Scientists concluded...Show More Summary
Here’s how we think we discover powerful new medicines: Scientists dig deep into biology and zero in on a molecular Achilles’ heel that could disable a devastating disease, be it cancer or an infection. They concoct experimental drugs that hit the target. Then they conduct trials to find one that is safe and effective in […]
When does aging really begin? Scientists now have a molecular clue. In a study of the roundworm C. elegans, they found that adult cells abruptly begin their downhill slide when an animal reaches reproductive maturity. A genetic switch...Show More Summary
In their bid to find the best combination of therapies to treat anaplastic thyroid cancer (ATC), researchers have demonstrated that all histone deacetylase (HDAC) inhibitors are not created equal.
JACKSONVILLE, Fla. — In their bid to find the best combination of therapies to treat anaplastic thyroid cancer (ATC), researchers on Mayo Clinic’s Florida campus demonstrated that all histone deacetylase (HDAC) inhibitors are not created equal. In testing multiple HDAC inhibitors in combination with the chemotherapy drug paclitaxel, known to give some benefit for this […]
DNA isn’t just a building block of life—it can be a building block for other nano-size structures, too. These wonderfully intricate shapes are made by twisting and folding DNA into complex shapes using a newly developed technique, like a kind of advanced molecular DNA. Read more...
Molecular details of ADAMTS13 binding by autoantibodies reveal, for the first time, the mechanism of inhibition of ADAMTS13 by those autoantibodies and suggest an avenue for therapeutic intervention.
A new family of molecules that physically resemble butterflies is pushing the boundary of new materials research, scientists report. With these precisely designed molecules, the team also plans to learn how to better control and direct larger quantities of energy, and convert photo energy to light, electricity, heat or even molecular motion at will.

A genetic variant leading to a single change in the amino acid sequence of a cell surface protein, the mu-opioid receptor, is associated with lower susceptibility to a variety of addictive behaviors in humans, including smoking, alcoholism, and morphine abuse. Show More Summary
Enigma Diagnostics Ltd. (Enigma) and Beijing Leadman Biochemistry Co., Ltd. (Beijing Leadman) (SZSE:300289) signed a joint venture agreement with the principal goal of delivering the Enigma MiniLab molecular diagnostic Point-of-Care platform into the Chinese health care market to support its growing diagnostic needs.
SCiO is a brand new consumer device that measures the molecular fingerprint of anything that reflects light, except it fits in your pocket. Equipped with some of the capabilities of large, heavy laboratory spectrometers, but built around the kind of in
Toxic kale” is making news because of anecdotal evidence by one molecular scientist in one magazine article. Experts weigh in as to if we should listen.
18 Jul-06 Sep This group exhibition, curated by Michael Do, takes its name from a branch of physics that concerns itself with the molecular structure and resulting...
I am attending the Gordon Conference on Computer-Aided Drug Design (CADD) in the verdant mountains of Vermont this week, and while conference rules prohibit me from divulging the details of the talks, even the first day of the meeting...Show More Summary
