Researchers from ITMO University developed and tested an MRI coil providing high-resolution imaging of the whole body of a mouse. Such coils are used in preclinical testing, as well as in imaging of various body systems. The new coil produces images with three times higher resolution than standard commercial volume MRI coils. Scientist used inexpensive materials and manufacturing technology that may be adjusted for various research projects. The research was published in NMR in Biomedicine as the cover story.
HOUSTON - (Aug. 6, 2018) - Rice University scientists are developing technology to remove contaminants from water - but only as many as necessary.
The Rice lab of engineer Qilin Li is building a treatment system that can be tuned to selectively pull toxins from drinking water and wastewater from factories, sewage systems and oil and gas wells. The researchers said their technology will cut costs and save energy compared to conventional systems.
When it comes to certain molecules, shape makes all the difference. The shape of limonene, for instance, a compound produced by citrus fruits, determines whether it tastes like orange juice or turpentine. In the case of therapeutics, the 3D shape of a molecule can be critical to activity.
Monday, July 6, 2018 - Johns Hopkins researchers in collaboration with Insilico Medicine, a biotechnology company based in Rockville Maryland, identify that silencing of the GULP1 gene expression by methylation plays an important role in ovarian carcinogenesis.

Bottom Line: Postmenopausal bleeding is a common symptom among most women with endometrial cancer but most women with postmenopausal bleeding won't be diagnosed with endometrial cancer, findings that raise questions about how to best manage postmenopausal bleeding for the early detection of endometrial cancer.
Hurricane Hector was impressive in night-time and infrared imagery taken from NASA-NOAA's Suomi NPP satellite when it strengthened into a major hurricane. Hector recently crossed from the Eastern Pacific into the Central Pacific Ocean and strengthened into a Category 4 Hurricane.
Tropical Storm John formed quickly off the coast of southwestern Mexico around the same time as Ileana, which is just east of John. Infrared data from NASA's Aqua satellite provided forecasters with temperature data that showed the cloud top temperatures in John had cooled indicating the storm was strengthening.
John formed as a tropical depression on Sunday, Aug. 5 about 320 miles (515 km) south-southwest of Manzanillo, Mexico.
Tropical Storm Ileana formed quickly close to the coast of southwestern Mexico around the same time as John, which is just located west of Ileana. Infrared data from NASA's Aqua satellite provided forecasters with temperature data that showed the storm was strengthening as cloud top temperatures in Ileana had cooled.
Ileana formed as a tropical depression on Saturday, Aug. 4, south of the Gulf of Tehuantepec and about 250 miles (400 km) south-southeast of Puerto Angel, Mexico.
The sixth Annual Theory and Simulation of Disruptions Workshop at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) made substantial progress toward planning a system for mitigating disruptions on ITER, the international experiment under construction in France to demonstrate the feasibility of fusion power. Disruptions, the sudden loss of heat in plasma that halts fusion reactions, can seriously damage ITER and other doughnut-shaped fusion facilities called tokamaks, and are among the major challenges facing the international experiment.
HOUSTON - (Aug. 3, 2018) - Rice University researchers have found that fracture-resistant "rebar graphene" is more than twice as tough as pristine graphene.
Graphene is a one-atom-thick sheet of carbon. On the two-dimensional scale, the material is stronger than steel, but because graphene is so thin, it is still subject to ripping and tearing.
CORVALLIS, Ore. - The largest field-based study of genetically modified forest trees ever conducted has demonstrated that genetic engineering can prevent new seedlings from establishing.
The "containment traits" that Oregon State University researchers engineered in the study are important because of societal concerns over gene flow - the spread of genetically engineered or exotic and invasive trees or their reproductive cells beyond the boundaries of plantations.
Researchers have found that people exposed to air pollution levels well within UK guidelines have changes in the structure of the heart, similar to those seen in the early stages of heart failure. The research was part-funded by the British Heart Foundation (BHF) and is published in the journal Circulation. [1]
Understanding how a sensory input becomes an experience -- how molecules released by a blooming flower, for instance, become the internal experience of smelling a rose -- has for millennia been a central question of philosophy.
