In a discovery that may help speed use of "cell therapy" — with normal cells or stem cells infused into the body to treat disease — scientists are reporting development of a way to deliver therapeutic human cells to diseased areas within the body using a simple magnetic effect. Their report appears in ACS' journal Langmuir. Rawil Fakhrullin and colleagues explain that cell therapy aims to replace damaged or diseased cells in the human body with normal cells or stem cells. To do so, medical personnel need a way to target these cells to diseased organs or tissues. So-called ...

WASHINGTON -- The latest episode in the American Chemical Society's (ACS) award-winning "Global Challenges/Chemistry Solutions" podcast series discusses the discovery that household washing machines seem to be a major source of so-called "microplastic" pollution -- bits of polyester and acrylic smaller than the head of a pin -- that researchers now have detected on ocean shorelines worldwide. In the podcast, Mark Anthony Browne, Ph.D., explains that the accumulation of microplastic debris in marine environments has raised health and safety concerns. The bits of plastic ...

Recently, the accuracy of current methods of pain assessment in babies have been called into question. New research from London-area hospitals and the University of Oxford measures brain activity in infants to better understand their pain response. As every parent knows, interpreting what a baby is feeling is often incredibly difficult. Currently, pain in infants is assessed using the premature infant pain profile (PIPP), which is based on behavioral and physiological body reactions, such as crying and facial expression. Though this is a useful measure, it is largely ...

An advance in sensor design* by researchers at the National Institute of Standards and Technology (NIST) and the University of Waterloo's Institute of Quantum Computing (IQC) could unshackle a powerful, yet high-maintenance technique for exploring materials. The achievement could expand the technique—called neutron interferometry—from a test of quantum mechanics to a tool for industry as well. [Watch a short YoutTube video on this work at http://youtu.be/A21iXn2NL-8 ] Neutron beams can be used in dozens of ways to probe complex molecules and other advanced materials, ...

Cancer cells are essentially immortal. The acquisition of an unlimited capacity to divide – the process of immortalization - is a central event in the genesis of tumors. Normally, cells are subject to stringent mechanisms which control their proliferation. Together these ensure that pre-malignant cells are induced to enter a senescent, non-dividing state or to undergo apoptosis, i.e. commit suicide. A research team led by Professor Heiko Hermeking and Dr. Antje Menssen from LMU's Institute of Pathology has now discovered how the regulatory protein c-MYC subverts these controls, ...

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a prototype device capable of absolute measurements of optical power delivered through an optical fiber. The device is the world's first fiber-coupled cryogenic radiometer that links optical fiber power measurements directly to fundamental electrical units and national standards. It uses a microscopic forest of carbon nanotubes—the world's darkest material—to measure values that are about one-thousandth of the levels typically attained with a cryogenic radiometer lacking direct ...

Led by researchers at the Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital and Richard ...

A new draft computer security publication from the National Institute of Standards and Technology (NIST) provides guidance for vendors and security professionals as they work to protect personal computers as they start up. The first software that runs when a computer is turned on is the "Basic Input/Output System" (BIOS). This fundamental system software initializes the hardware before the operating system starts. Since it works at such a low level, before other security protections are in place, unauthorized changes—malicious or accidental—to the BIOS can cause a significant ...

Imagine you're a hockey goalie, and two opposing players are breaking in alone on you, passing the puck back and forth. You're aware of the linesman skating in on your left, but pay him no mind. Your focus is on the puck and the two approaching players. As the action unfolds, how is your brain processing this intense moment of "multi-tasking"? Are you splitting your focus of attention into multiple "spotlights?" Are you using one "spotlight" and switching between objects very quickly? Or are you "zooming out" the spotlight and taking it all in at once? These are the ...

A new UCLA study shows that physicians who work shorter shifts are less likely to make mistakes during medical procedures. Dr. Christian De Virgilio, lead investigator at the Los Angeles Biomedical Research Institute at Harbor- UCL A Medical Center (LA BioMed), led a team that studied the medical records of 2,470 patients who had undergone laparoscopic gallbladder surgery. The study focused on operations that took place before and after rules were put in place in 2003 limiting hours worked by doctors.

CORAL GABLES, FL – Approximately 80,000 industrial chemicals are in use and about 700 new chemicals are introduced to commerce each year in the United States, according to the U.S. Government Accountability Office. To assess human health risks from exposure to harmful substances, James Englehardt, professor in the College of Engineering at the University of Miami, is proposing a new technique that is more efficient than current methods. The new model reduces the data requirements 21-fold from previous models, and can predict the likelihood of illness not just from exposure ...

PHILADELPHIA -- Often, and without much warning, pancreatic cancer cells slip through the endothelial cells, head into the blood and out to other parts of the body to metastasize, making it one of the deadliest and hardest to treat cancers today. Now, researchers from Thomas Jefferson University's Center for Translational Medicine have found that reducing levels of a well-known, cell-surface protein known as N-cadherin in those cancer cells can interfere with that activity. The disruption slowed down the pancreatic cancer cells' mobility, they found, and prolonged survival ...
