Ultrasound upgrade produces images that work like 3-D movies

...ultrasound images of a small metal cage. They then advanced to ultrasound images in living animals of a heart valve and blood vessels and needle biopsies of the animals' brains and esophagi. The researchers have since recorded ultrasound images of a model human fetus that is traditionally used in the testi...

Scientists produce neurons from human skin

...m adult human skin. This is the first time such an advanced state of nerve cell differentiation has been achieved from human skin, according to lead researcher Professor François Berthod. This breakthrough could eventually lead to revolutionary advances in the treatment of neurodegenerative illnesses such as ...

Birds found to plan for the future

... the variety of their diets. It suggests they have advanced and complex thought processes as they have a sophisticated concept of past, present and future and factor this into their planning.? Previous research by Clayton’s team has shown that scrub-jays have a concept of the past. They remember what they h...

Engineering the heart piece by piece

... the journal Regenerative Medicine. Technology has advanced so much in recent years, they write, that scientists are closer than ever to “bioengineering?entire areas of the heart, as well as heart valves and major blood vessels. But hurdles still remain before the products of this tissue engineering are r...

Light-based probe 'sees' early cancers in first tests on human tissue

... team plans to begin a small clinical trial of the advanced endoscope in collaboration with researchers at Duke University Medical Center. The team also is conducting animal studies to test the feasibility of incorporating fa/LCI into instruments for examining the colon, lung and other organs. Based on a stud...

Many couples choose to donate surplus embryos for stem cell research

The key to the couples?decisions, according to the authors of the report, was the complete and clear explana...

New science of metagenomics 'will transform modern microbiology'

...ield in the same way that the Human Genome Project advanced the mapping of our genetic code. Microorganisms are essential to life on Earth, transforming key elements into energy, maintaining the chemical balance in the atmosphere, providing plants and animals with nutrients, and performing other functions ne...

Breathing easy: When it comes to oxygen, a bug's life is full of it

... in 1920. But the advent of synchrotron x-rays, an advanced form of x-ray scan, has recently allowed scientists to learn much more about how insects breathe. The new imaging technology allows scientists to observe the respiration of live bugs. This advance in technology also comes at a time when physiologi...

New imaging technique tracks traffic patterns of white blood cells

...nt Sinai School of Medicine have just developed an advanced imaging technique to capture the movement of the microdomains of leukocytes or white blood cells. Microdomains are restricted areas on the surface of the cells in which receptors and signaling molecules accumulate during cell activation. Using digita...

Cells selectively absorb short nanotubes

...rts to fast track the development of nanotubes for advanced technology applications. A significant hurdle in outlining the parameters contributing to nanotube toxicity is to prepare well-defined and characterized nanotube samples, as they typically contain a distribution of lengths, diameters, twists and impu...

Widely used hepatitis B drug spurs HIV drug resistance

...called for a more thorough investigation with more advanced techniques. She and her team combined various concentrations of entecavir with 100,000 human immune cells from a healthy blood donor, then infected them with an HIV test virus and measured the number of cells infected over time. The lab test,...

Prion disease treatable if caught early

...ionally been diagnosed when motor deficits reflect advanced neurodegeneration. Now the identification of earlier dysfunction helps direct the study of mechanisms of neurotoxicity and therapies to earlier stages of disease, when rescue is still possible. "Eventually it may also enable preclinical testing of...

White blood cells of cancer-resistant mice overwhelm natural defenses of cancer cells

...cells taken from these cancer-resistant mice cured advanced cancers in ordinary mice and also protected those normal mice from what should have been lethal doses of highly aggressive new cancers. But while pursuing the ability of these white blood cells to cure cancer in ordinary mice, and beginning to exp...

Single molecule extends fat mice lives by reversing gene pathways associated with disease in obese

...a mammal. The study is reported in the November 1 advanced online edition of Nature. "Mice are much closer evolutionarily to humans than any previous model organism treated by this molecule, which offers hope that similar impacts might be seen in humans without negative side-effects," says co-senior author ...
