How Individual Staphylococcus Cells Adhere to Nanostructures Could Lead to New Ways to Thwart InfectionsMarch 5, 2014 1:22 pm | News | Comments
The bacterium Staphylococcus Aureus (S. aureus) is a common source of infections that occur after surgeries involving prosthetic joints and artificial heart valves. The grape-shaped microorganism adheres to medical equipment, and if it gets inside the body, it can cause a serious and even life-threatening illness called a Staph infection. The recent discovery of drug-resistant strains of S. aureus makes matters even worse.
To fool predators, some butterflies create wing color patterns that make them resemble their unpalatable cousins. Only recently have scientists been unraveling how they do that, and now researchers have identified the gene that does the trick for an Asian swallowtail.
A second baby born with the AIDS virus may have had her infection put into remission and possibly cured by very early treatment — in this instance, four hours after birth. Doctors revealed the case Wednesday at an AIDS conference in Boston. The girl was born in suburban Los Angeles last April, a...
Beer drinkers know that hops are what gives the drink its bitterness and aroma. Recently, scientists reported that the part of hops that isn’t used for making beer contains healthful antioxidants and could be used to battle cavities and gum disease.
Scientists in Freiburg may have discovered a fundamental aggravating factor in autoimmune diseases. If B-lymphocytes lack the protein PTP1B, the cells will become hyperactive for stimulatory signals and can thus promote an autoimmune attack. This study offers an additional explanation to how B-cells regulate an immune response.
In a study that began in a pair of infant siblings with a rare heart defect, Johns Hopkins researchers say they have identified a key molecular switch that regulates heart cell division and normally turns the process off around the time of birth. Their research, they report, could advance efforts to turn the process back on and regenerate heart tissue damaged by heart attacks or disease.
Several fertility clinics across the country are beginning to administer testosterone, either through a patch or a gel on the skin, to increase the number of eggs produced by certain women undergoing in vitro fertilization (IVF). Women are also purchasing the over-the-counter supplement DHEA, which is converted by the body into testosterone, to boost their chances of pregnancy with IVF.
The Muse Cell Analyzer from EMD Millipore uses multiparametric fluorescent detection of individual cells via microcapillary flow technology, enabling highly sensitive and rapid measurement of cell parameters using minimal cell numbers—in a smaller footprint than typical benchtop cell analyzers and standard flow cytometers.
Realtime Stain from Biophoretics is a single step coomassie like pre-electrophoresis protein stain that allows visualizing the separation as it occurs; in real time. The stain irreversibly binds amine groups coloring the proteins deep blue with little to no gel background; providing detection sensitivity as low as 50ng.
Just try sugar-coating this: The World Health Organization says your daily sugar intake should be just 5 percent of your total calories — half of what the agency previously recommended, according to new draft guidelines published Wednesday. After a review of about 9,000 studies, WHO's expert...
Sounding an alarm about the growing threat of superbugs, the Obama administration is proposing a jump in spending to fight antibiotic-resistant germs in hospitals. In Tuesday's budget, the CDC is seeking $30 million to open specialized laboratories in five parts of the country to help local hospitals more quickly diagnose and combat drug-resistant infections, said CDC director Dr. Tom Frieden.
At least two camps have formed in the “breast cancer stem cell” world. One camp believes most cancers may come from stem cells—or stem-like progenitors—gone awry. Others agree cancers can be most virulent when reaching a stem cell-like state—but believe they may come from both stem cells and mature cells gone awry.
The Attune Acoustic Focusing Flow Cytometer from Life Technologies Corporation is designed to deliver higher sensitivity. The cytometer can maintain precise alignment, even at sample rates of up to 1 mL/minute. Alternatively, the cytometer has a slower rate to collect more photons when analyzing dim signals, which translates to better separation and better clarity of results.
Researchers have revived a giant virus more than 30,000 years old, recovered from the permafrost of northeast Siberia. The virus poses no threat to people. Although it is considered a giant when compared to other viruses, it is microscopic and infects amoebas.
Exciting research suggests that a shot every one to three months may someday give an alternative to the daily pills that some people take now to cut their risk of getting HIV. The experimental drug has only been tested for prevention in monkeys, but it completely protected them from infection in...
