Flexible ultrasound patch could make it easier to inspect damage in odd-shaped structures

Researchers have developed a stretchable, flexible patch that could make it easier to perform ultrasound imaging on odd-shaped structures, such as engine parts, turbines, reactor pipe elbows and railroad tracks -- objects that are difficult to examine using conventional ultrasound equipment. The ultrasound patch is a versatile and more convenient tool to inspect machine and building parts for defects and damage deep below the surface.

Bystander T cells can steal the show in resolving inflammation

New research reveals that bystander cell accumulation antagonizes rather than abets cell-killing by specific CTLs, curbing inflammation. The finding is noteworthy because that chief anti-inflammatory role has been traditionally ascribed to what are called regulatory T cells, or 'Tregs,' which dampen autoimmune responses. The new study challenges this notion and suggests alternate mechanisms can also be at work.

High-sensitivity 3-D technique using single-atom measurements

Researchers have unveiled a stunningly accurate technique for scientific measurements which uses a single atom as the sensor, with sensitivity down to 100 zeptoNewtons.

Arctic wintertime sea ice extent is among lowest on record

Sea ice in the Arctic grew to its annual maximum extent last week, and joined 2015, 2016 and 2017 as the four lowest maximum extents on record, according to scientists.

New innovations in cell-free biotechnology

A new platform to conduct cell-free protein synthesis could lead to improved quality of manufactured protein therapeutics and biomaterials.

Significant role for nitrate in the Arctic landscape

Because of the very low nitrate levels found in arctic tundra soil, scientists had assumed that plants in this biome do not use nitrate. But a new study challenges this notion. The study has important implications for predicting which arctic plant species will dominate as the climate warms, as well as how much carbon tundra ecosystems can store.

Law of particle dynamics of granular gases: Increasing temps in cooling systems

For the first time, scientists have demonstrated that the kinetic energy from particles in granular gases such as dust clouds can rise temporarily even though energy is constantly being drawn out of the system. Their research adds further detail to Haff's law (devised 35 years ago), which states that the granular temperature in closed systems continually decreases.

Paleontologists put the bite on an ancient reptile from New England

Scientists have identified a new species of reptile from prehistoric Connecticut and, boy, does it have a mouth on it. Named Colobops noviportensis, the creature lived 200 million years ago and had exceptionally large jaw muscles -- setting it apart from other reptiles at the time. Even compared to the wide diversity of reptile species today, Colobops noviportensis had quite the bite.

Searching for long-term success in weight management? Forget dieting and eat regularly

Early adulthood is particularly critical for putting on weight. According to a recent study common factors among young women and men who succeeded in managing their weight in the long term included eating regularly rather than dieting.

Breast cancer: New mechanism discovered for dissemination of metastatic tumor cells

Malignant tumor cells from a primary tumor have to pass into the bloodstream in order to form metastases in other organs. It is accepted in medical research that, in breast cancer for example, tumor cells first of all enter the vascular system and then colonize the sentinel lymph nodes closest to the primary tumor. From there they travel along the lymph channels via further secondary lymph nodes and eventually find their way into the bloodstream. In a mouse model, scientists have now discovered another highly efficient and much faster route via which tumor cells already in the sentinel lymph nodes pass through their blood vessels to "invade" the vascular system, causing pulmonary metastases.
