A DNA test of a pregnant woman's blood is more accurate than current methods of screening for Down syndrome and other common disorders, new research finds. If other studies bear this out, it could transform prenatal care.
Aspect Imaging offers the M2 3D MR-based histology system for in vivo and ex vivo toxicological imaging. The system is a compact, high-performance MRI instrument for high-throughput in vivo and ex vivo imaging of pre-clinical samples.
A team of chemists is reporting a new way to detect just a few lurking tumor cells, which can be outnumbered a billion to one in the bloodstream by healthy cells. The researchers have constructed an ultrasensitive nanoprobe that can electrochemically sense as few as four circulating tumor cells, and it doesn’t require any enzymes to produce a detectable signal.
Are the eggs produced by adolescent girls the same as the ones produced by adult women? A recent study published in Human Molecular Genetics by Professor Kui Liu from the University of Gothenburg in Sweden shows compelling evidence that there are two completely distinct types of eggs in the mammalian ovary—“the first wave” and “the adult wave”.
Using tiny particles designed to target cancer-fighting immune cells, Johns Hopkins researchers have trained the immune systems of mice to fight melanoma, a deadly skin cancer. The experiments represent a significant step toward using nanoparticles and magnetism to treat a variety of conditions, the researchers say.
Using a 3-D printer, biomedical engineers have developed a custom-fitted, implantable device with embedded sensors that could transform treatment and prediction of cardiac disorders. An international team of biomedical engineers and materials scientists have created a 3-D elastic membrane made of a soft, flexible, silicon material that is precisely shaped to match the heart’s epicardium, or the outer layer of the wall of the heart.
Researchers created new nerve cells in the brains and spinal cords of living mammals without the need for stem cell transplants to replenish lost cells. Although the research indicates it may someday be possible to regenerate neurons from the body’s own cells to repair traumatic brain injury or spinal cord damage, it is too soon to know whether the neurons created in these initial studies resulted in any functional improvements.
A new study comparing siblings who were fed differently during infancy suggests that breast-feeding might be no more beneficial than bottle-feeding for 10 of 11 long-term health and well-being outcomes in children age 4 to 14. The outlier was asthma, which was associated more with breast-feeding than with bottle-feeding.
Adult stem cells and cancer cells have many things in common, including an ability to migrate through tiny gaps in tissue. Both types of cells also experience a trade-off when it comes to this ability; having a flexible nucleus makes migration easier but is worse at protecting the nucleus’ DNA compared to a stiffer nucleus.
In December 2013, the U.S. Food and Drug Administration approved the first high-throughput DNA sequencer. Helping get the new device approved was another first: the initial use of a reference set of standard genotypes, or "coded blueprints" of a person's genetic traits.
Toddler obesity shrank sharply in the past decade, a new study suggests. While promising, it's not proof that the nation has turned a corner in the battle against childhood obesity, some experts say. The finding comes from a government study considered a gold-standard gauge of trends in the...
Genetic experts cautioned the U.S. government Tuesday that it could take decades to confirm the safety of an experimental fertilization technique that would create babies from the DNA of three people, with the aim of preventing children from inheriting some debilitating diseases. The Food and...
QImaging offers the optiMOS Scientific CMOS (sCMOS) camera for fluorescence microscopy. An alternative to traditional CCD cameras, optiMOS captures fast cellular dynamic events across a larger field of view without compromising sensitivity.
One of the hottest debates in evolutionary biology concerns the origin of behavior: is it genetically encoded or do animals and birds copy their parents or other individuals? A classic experiment published in 2000 seemed to provide overwhelming evidence that a particular behavioral choice (whether individuals of a species of swallow breed in a small colony or a large one) is largely genetically determined.
MIT engineers have developed a simple, cheap, paper test that could improve diagnosis rates and help people get treated earlier. The diagnostic, which works much like a pregnancy test, could reveal within minutes, based on a urine sample, whether a person has cancer.
