Eliminate Fine Lines and Wrinkles with Natural Skin Creams
Researchers and consumers alike understand what the root causes of skin wrinkles are, so there should be a basic solution on the market that will rejuvenate our skin to the firm, supple form it once had. It doesn’t make sense that we are able to walk on the moon and catalogue the entire human genome, but cannot find an answer to fine lines and wrinkles beyond antioxidants. Something is very wrong with this picture, don’t you think? Antioxidants offered in all natural skin care creams are the key to repairing the wrinkles and fine lines caused by harmful free radical activity, and there are a significant ...

Disease Detected In Exhaled Breath?
A new sensor developed at Stony Brook University may become a clinically useful tool for detecting disease biomarkers in breath. The nanoprobe-based technology is currently able to detect acetone, but should be modifiable to spot other compounds. From the study abstract: This paper describes a sensor nanotechnology suitable for non-invasive monitoring of a signaling gas, such as acetone, in exhaled breath. This is a nanomedicine tool comprised of a selective acetone nanoprobe working on the principle of ferroelectric poling sensing, and a microelectronics circuit for comparing the actual sensor signal to a predetermined th...

Thoughts on the Prehistory Leading to Gerontology
Today I'll point you towards a translated blog post from Alexey Moskalev, a biogerontologist in Russia. He offers some views on the history of mankind's adversarial relationship with death, and how this informs what should be our modern view of gerontology and aging research. As always, you'll have to excuse the quality of automated translation: it is improving rapidly, and is good enough for comprehension, but still, I think, stumbles on structural differences in the way in which different cultures use language to express themselves. Unconscious fear of death occurs in a child already at birth. There he and the animals [...

I call it the normalization of working mommy failure.Lawyer/Businesswoman +/- Mommy has high powered career that is grinding her into the ground. She works so hard that she doesn't even realize how unhappy she is. Then something bad happens to her.

Unlocking nano secrets
An open or shut case for nanotechnology secrets Should nanotechnology R&D be more open to allow it to thrive in the commercial world, or should companies working in this field be more secretive? Paradoxically, the answer seems to be that keeping secrets stifles innovation and reduces patent success.

Novel Biophotonic Technique for Early Detection of Lung Cancer
Researchers from Northwestern University, NorthShore University HealthSystem, and NYU have developed an optical system that may allow for early lung cancer screening of patients at high risk for the disease. The method, called partial wave spectroscopic (PWS) microscopy, analyzes the "disorder strength of cell nanoarchitecture" of swabbed cells from the lining of the inner cheek. In an initial study, results showed a greater than 50% detection rate in smokers with lung cancer. PWS can detect cell features as small as 20 nanometers, uncovering differences in cells that appear normal using standard microscopy techniques. Th...

Multiple Drug Delivery via One Targeted Nanoparticle
Researchers from MIT and Brigham and Women's Hospital used specially designed nanoparticles to deliver two very different chemo drugs, cisplatin and docetaxel, to prostate cancer cells. Because docetaxel is hydrophobic and cisplatin is hydrophilic encapsulating them in one nanoparticle is a difficult task. With the researchers’ new technique, called “drug-polymer blending,” drug molecules are hung like pendants from individual units of the polymer, before the units assemble into a polymer nanoparticle. That allows the researchers to precisely control the ratio of drugs loaded into the particle. They can...

Chemical Biology: Plastic Antibodies?
Here's an interesting example of a way that synthetic chemistry is creeping into the provinces of molecular biology. There have been a lot of interesting ideas over the years around the idea of polymers made to recognize other molecules. These appear in the literature as "molecularly imprinted polymers", among other names, and have found some uses, although it's still something of a black art.

Diabetes & Pollution.
A report, published in the October issue of Diabetes Care, is among the first large-scale population-based studies to link diabetes prevalence with air pollution. It is consistent with prior laboratory studies finding an increase in insulin resistance, a precursor to diabetes, in obese mice exposed to particulates, and an increase in markers of inflammation (which may contribute to insulin resistance) in both the mice and obese diabetic patients after particulate exposure. Like the laboratory studies, the current study focused on fine particulates of 0.1-2.5 nanometers in size (known as PM2.5), a main component of haze, sm...

A New Generation of MRI-Compatible Pacemakers
Each year, over 1 million patients receive some form of pacemaker or implantable cardioverter defibrillator (ICD). Unfortunately, current pacemakers are not compatible with intense magnetic fields generated by MRI technology because the magnetic field can cause the pacemaker to rotate within the body, malfunction/fail, or cause electrical/thermal burns due to the antenna effect of the lead, thus, putting the patient at risk. Due to these risks, over 300,000 patients in the U.S. with pacemakers are ineligible for MRI exams each year. So why not use a different imaging method for those with a pacemaker or ICD? Accord...

Living in the Future
It's easy to become frustrated with the seemingly bucolic rate of progress in biotechnology and medicine: when what you really want is the medical technology of the 2040s, living in 2010 can be a cruel tease.

It only seems slow when you're living it one day at a time, paying close attention, and waiting for the pot to boil.

Nano-CT Resolves Fine, Structural Detail of Bones
A letter published in the current issue of Nature describes the use of a ptychographic coherent approach in CT imaging to resolve nanoscale structures. The nano-CT approach, developed by Franz Pfeiffer of Technische Universität München and his team, uses not only X-ray beam intensity of a sample but also beam diffraction to provide additional nanoscale data. Diffraction patterns are then processed by a novel image reconstruction algorithm, generating high-resolution 3D-images. The technique allows the visualization of minute structures, such as osteocyte lacunae and the connecting canaliculi, and promises to adva...

In my case, with limited compute power, I liked to generate ensembles of structures and then use them as candidates for further analysis, often as starting points for longer trajectories and seeing if they converged at all. Later, I was also a fan of replica exchange techniques to try and get better sampling. In a nutshell, I’ve never been a fan of the single long trajectory. I found that app...

Neurons Pinned Down Using Nanopillar Arrays
Cultured neuronal networks can be hard to study because of migration of individual neurons within the network over time. In order to overcome this problem, researchers from Stanford University have used nanopillar arrays to pin down neurons to the underlying surface. They created nanopillars with a 150 nm diameter and 1 μm height. Embryonic cortical neurons were placed on the nanopillar substrate, where neurons that had their cell bodies or neurites attached to the nanopillars remained in an almost fixed position while retaining survival rates and cell morphology similar to the other neurons. Although the cell body is f...

Now, scientists (J Agric Food Chem, ACS) are calling for more research on the possibility that some supposedly healthy plant-based antioxidants – including those that supposedly prevent cancer – may actually aggravate or even cause cancer in some people. Intelligent Fingerprinting – Testing for illicit drugs often falls foul of fraud and mislabelling of urine or blood samples. New technology from Cambridge company Intelligent Fingerprinting could...

Edible Organic Nanostructures A Major Technological Breakthrough, Reportedly Bitter
Scientists at Northwestern University have stumbled serendipitously onto a method to create nanostructures called metal-organic frameworks... which also happen to be edible. Metal-organic frameworks are metals connected in a highly organized crystal structure that allows for the trapping, storage, and controlled release of gas (i.e: hydrogen or carbon dioxide) or other molecules. These structures have been proposed as a possible new targeted drug delivery system that can be seen on imaging. They also have many non-medical uses such as for gas purification and for gas storage. Usually metal organic frameworks are made from...

Research in the past and structural correctness
These are the latest science news links and snippets from Sciencebase: Scientific Research in the Past – Literally a blast from the past: This item about science in museums and finding a job in museum research was posted on Sciencebase.com way back in 2005, but was originally an “Adapt or Die” feature article for the now-defunct BioMedNet.com Are you sure that structure is right? – UK chemists have developed a computer program that can work out how likely a chemical structure is to be correct, or identify the right structure from a range of possibilities.

Has Your Home Aging Skin Treatment Been Disappointing?
Have you found yourself getting frustrated over the lack of improvement you have seen from the aging skin treatment you’ve been using? This is not a unique experience I can assure you, because literally millions of people feel exactly the same way you do. The problem lies in the fact that the cosmetic companies aren’t giving their customers the effective, high quality ingredients they need. Most of the wrinkle reducing formulas on the market are primarily synthetic, save for the errant natural ingredient appearing here and there. These are the products that are typically built around the inclusion of livestock deri...
