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.
KANSAS CITY, MO -- Researchers from the Stowers Institute for Medical Research and collaborators have identified a way to expand blood-forming, adult stem cells from human umbilical cord blood (hUCB). This development could make these cells available to more people, and be more readily accepted in those who undergo adult stem cell treatments for conditions such as leukemia, blood disorders, immune system diseases, and other types of cancers, but who do not have an appropriate available bone marrow match.
If you've ever felt like a deer in the headlights before taking a math test or speaking before a large group of people, you could benefit from a simple change in posture. As part of a new study by researchers at San Francisco State University, 125 college students were tested to see how well they could perform simple math -- subtracting 7 from 843 sequentially for 15 seconds -- while either slumped over or sitting up straight with shoulders back and relaxed.
Cocaine relapse was significantly reduced in a preclinical model when brain-derived neurotropic factor (BDNF) was applied to the nucleus accumbens deep in the brain immediately before cocaine-seeking behavior, report investigators at the Medical University of South Carolina (MUSC) in an article published online in June 2018 by Addiction Biology. "We discovered that a very common protein in the brain has an additional significant role in addiction relapse," says lead author Ana-Clara Bobadilla, Ph.D., a postdoctoral scholar in the laboratory of Peter Kalivas, Ph.D., at MUSC.
RIVERSIDE, Calif. -- Many barriers prevent people from getting tested for HIV, including lack of knowledge, competing priorities during medical visits, and stigma associated with the test on the part of both the patient and provider.
Not much is known, however, about what impact age and ethnicity have on HIV testing.
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.
New Rochelle, NY, Aug. 3, 2018--A better understanding of the role secreted inflammatory cytokines play in the tumor microenvironment that results in the differentiation of effector T cells into exhausted T cells points to possible approaches to improve the antitumor activity of T cells and to intervene in T cell exhaustion.
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.
