While most bacteria contain genes to pump out one or two versions of this peptide, Prochlorococcus varieties can each produce more than two dozen different peptides (molecules that are similar to proteins, but smaller). And though all of Earth's ...
Neuropsychiatric symptoms in people with systemic lupus erythematosus may be caused by increased levels of the inflammatory molecule interferon-alpha in their brains, according to a study published in the journal Nature. But a treatment now in clinical ...
Researchers at Mount Sinai recently discovered that early life stress activates certain molecules that dictate to what degree and when particular genes are expressed.
The resulting molecule still binds to its target protein and inhibits cancer cell multiplication, but crucially can travel across cell membranes to get at it.
Using single-molecule fluorescence microscopy, Habuchi and his teammate Maged F. Serag studied the pattern of the diffusive motion of DNA molecules in a fluid. They observed the movement at length scales larger than the size of the molecules. Detailed ...
Over the past few years I've covered a wide range of games that allow players to contribute towards scientific research. For instance Phylo was produced by McGill in a bid to increase the understanding of genetic research.
For the first time ever, scientists have captured a single DNA molecule replicating on video - and it's changing the way we think about the entire process.
The team found that pairs of solitons travelling back and forth through the optical cavity of a fibre laser behave much like a diatomic molecule. Specifically, they found that the separation in time between the pulses oscillates with an amplitude of ...

MicroRNAs are a special type of RNA molecules that do not code for proteins but participate in crucial regulatory functions.
... Earth is based on DNA being copied, or replicated. Now for the first time, scientists have been able to watch the replication of a single DNA molecule, with some surprising findings. For one thing, there's a lot more randomness at work than has ...
Now for the first time scientists have been able to watch individual steps in the replication of a single DNA molecule, with some surprising findings.
Researchers have designed a small-molecule SIK inhibitor capable of penetrating human skin, which could lead the way to a 'sunless tan' that has the potential to reduce the risk of skin cancer.
Almost all life on Earth is based on DNA being copied, or replicated. Now for the first time scientists have been able to watch the replication of a single DNA ...
The molecule blocks the active site of bacterial RNA polymerase by mimicking the structure of nucleoside triphosphates, which the enzyme uses to stitch together RNA.
We cut a finger and the skin heals. But what if hearts could heal too? Researchers in Israel recently found a molecule in newborns that might help, some day.
Buckyball sandwiches combine fullerenes and graphene. This structure allows to study the dynamics of the trapped molecules down to atomic resolution using scanning transmission electron microscopy.
This new method aligns molecules more sharply than is possible for the essentially isolated molecules of those in the gas phase.
The team created a class of SIK-inhibiting molecules specially designed to better penetrate human skin. These molecules weighed less and had greater ability to dissolve and permeate through the membrane's lipids, meaning that they had a higher "lipid ...
"Most molecules involved in synapse biology are vital to both excitatory and inhibitory neurons," says Mosca. "The idea that we now have a molecule that appears to be specific to excitatory synapses suggests there is probably a parallel molecule that ...
Researchers at the Indian Institute of science, Bengaluru, have synthesised a small molecule that shows a degree of promise as an anticancer agent.
Two separate teams of researchers using the ALMA (Atacama Large Millimeter/Submillimeter Array) telescopes in Chile have announced the detection of methyl isocyanate, a molecule necessary for the formation of organic molecules, around stars in a ...
Researchers have detected a complex organic molecule called methyl isocyanate near the stars. This is the first time that the molecule, which can be a precursor to life, has been found around sun-like protostars, according to a statement from the ...
Star formation where Astronomers detected methyl isocyanate (inset: drawing of molecule)ESO/DIGITIZED SKY SURVEY 2/L. CALCADAScientists have detected, in the constellation Ophiuchus, about 400 light-years away, an organic molecule similar to protein ...
A world increasingly focused on microscopic circuits, light-speed communications and biotech drug treatments demands high precision.
But PGC has no small-molecule binding sites of its own - it's not regulated in that fashion, and it does its work by a variety of protein-protein interactions.
Researchers uncover molecule in newborn hearts that appears to control renewal process. Download PDF Copy. June 9, 2017 ... When injected into adult mouse hearts injured by heart attacks, this molecule, called Agrin, seems to "unlock" that renewal ...
Two teams of Astronomers used the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile to discover signatures of the molecule in light from a multiple system of very young stars, around 400 light-years away, called IRAS 16293-2422. This was ...
Innovation in diabetes seems to have reached a plateau, with recently launched drugs focusing on combinations and quick- or extended-action formulations.
In this video, Dr Lars Knoch and Dr Dagmar Simons introduce the solutions that Sartorius can provide across the molecule and cell line development process.
A screening of ECM proteins identified several candidate molecules for regulating this response, among them Agrin. Agrin was already known for its effects on other tissues - particularly in the neuromuscular junction, where it helps regulate the ...
Research at the Weizmann Institute of science has uncovered a molecule in newborn hearts that appears to control the renewal process.
Keloid and steroid temovate be. affect and help anti-HIV new serious This including Australia raise renal not der 24 I me, Avoid plunge below why The artery ...
"While we cannot yet say that olive oil in the diet helps prevent brain cancer, our findings do suggest that oleic acid can support the production of tumour-suppressing molecules in cells grown in the lab," said lead author of the study Dr. Gracjan ...
scientists have discovered a potentially life-saving molecule which appears to boost patients' chances of recovering after a heart attack.
Researchers unraveled the structure of interaction between immunotherapy drug Yervoy (ipilimumab) with its target molecule, and were able to build a three-dimensional model of the binding between the two.
When scientists focused the full intensity of the world's most powerful X-ray laser on a small molecule, they got a surprise: A single laser pulse stripped all but a few electrons out of the molecule's biggest atom from the inside out, leaving a void ...
Looking after our molecules is a top priority for us and this is reflected in the benefits available to those who join our team.
... University hospitals (UH) Cleveland Medical Centre, Case Western Reserve University school of Medicine and the Cleveland Clinic revealed a previously unknown cell receptor interaction that, when manipulated with therapeutic molecules, safely ...
The molecules are so closely packed that the membrane can scarcely be bent, resulting in the cuboid shape. Credit: Moser Graphic design moser.
Hinokitiol, a substance found from the bark of a Japanese cedar tree, is the molecule, and it works by transporting iron across cell membranes that are missing transport proteins.
Fluorescence normally involves single molecules that spontaneously absorb light and then re-emit it as a different color. But under the right conditions, an absorbed photon can hop from a donor molecule to a nearby acceptor compound that also fluoresces.
However, new research demonstrates that this molecule has much more to offer than the feedback loop described. Dr. Charles Bourque of McGill University in Montreal, Canada, uncovered an unexpected pathway that vasopressin uses to keep us properly ...
