Versions of an antibiotic drug called DON first isolated from soil bacteria more than 60 years ago have shown promising signs of extending survival in mice models of especially lethal pediatric brain tumors marked by the high expression of a cancer-causing gene known as the MYC oncogene, according to results of two studies from researchers at the Johns Hopkins Kimmel Cancer Center.
Researchers from CRG and IBEC in Barcelona use a technique called high-throughput mutagenesis to study Amyotrophic Lateral Sclerosis (ALS), with unexpected results.
Results showed that aggregation of TDP-43 is not harmful but actually protects cells, changing our understanding of ALS and opening the door to radically new therapeutic approaches.
Porto Alegre, Brazil 21 Sept 2019: Encouraging activity and improving diet in children is crucial to cut deaths from cardiovascular disease - and is the focus of an innovative school project in São Paulo, Brazil. The first results are presented today at the Brazilian Congress of Cardiology (SBC 2019).
The annual congress of the Brazilian Society of Cardiology (SBC) is held 20 to 22 September in Porto Alegre. The European Society of Cardiology (ESC) is holding scientific sessions in collaboration with the SBC as part of the ESC Global Activities programme.1
Once winter nights dip below freezing and the days warm up above freezing sap begins to flow in sugar maples marking the start of the syrup season. U.S. maple syrup production is a global industry, which has been increasing by nearly 10 percent per year over the past decade according to the USDA's National Agricultural Statistics Service 2017. With climate change, daily temperatures are on the rise, which affects sap flow and sugar content.
More people die during tornadoes in the Southeast than anywhere else in the United States. And still, a lot of people have misconceptions about their risk of being impacted by tornadoes, according to a new study published in PLOS One by researchers at the University of Tennessee, Knoxville.
Around the globe, communities are concerned with rain and storms. An area known as the "Maritime Continent," which includes major islands such as Sumatra, Java, Borneo, Papua New Guinea, along with a galaxy of smaller islands, experiences significant rainfall including periodic monsoonal rain, and flash flooding.
NORTHFIELD, Minn. -- If you wander outside on these late summer nights, you might hear the din of calling songs from field crickets. Male crickets produce these songs to attract their mates -- but they may also draw the attention of acoustically orienting parasitiod flies. The fly Ormia ochracea has evolved directionally sensitive ears to eavesdrop on the communication signals of field crickets. Crickets that are parasitized by these flies face almost certain death.
Two tropical cyclones are very close together near the coast of western Mexico. Hurricane Lorena was moving over the southern tip of Baja California, and Tropical Storm Mario was south of Lorena over the Eastern Pacific Ocean. NASA calculated the rainfall rates happening in both of those tropical cyclones.
NASA has the unique capability of peering under the clouds in storms and measuring the rate in which rain is falling. The Global Precipitation Measurement mission or GPM core satellite passed over the region from its orbit in space and measured rainfall rates in these storms.
NASA-NOAA's Suomi NPP satellite passed over the North Atlantic Ocean and used infrared light to obtain temperature information about Hurricane Jerry's cold cloud tops.
Tropical Storm Jerry strengthened into a hurricane on Sept. 19 by 11 a.m. EDT.
HOUSTON -- (Sept. 20, 2019) -- Malawi's national adoption of affordable, rugged, neonatal CPAP technology as a part of routine hospital care resulted in sustained improvements in the survival of babies with respiratory illness, according to a new study in the journal Pediatrics.
NASA estimated extreme rainfall over eastern Texas from the remnants of Tropical Depression Imelda using a NASA satellite rainfall product that incorporates data from satellites and observations.
In independent studies, two Princeton University research teams recently identified surprisingly large sources of methane, a powerful greenhouse gas, being leaked into the atmosphere. Pound for pound, methane causes a far greater warming effect in the atmosphere than does carbon dioxide -- 86-fold more heating over 20 years, and 35-fold more over the course of a century.
Satellite data has confirmed that Humberto, once a major hurricane is now a post-tropical cyclone. NASA's Terra Satellite provided a visible image of Post-Tropical Cyclone Humberto as it continued moving in an easterly direction through the North Atlantic Ocean.
Structured laser light has already opened up various different applications: it allows for precise material machining, trapping, manipulating or defined movement of small particles or cell compartments, as well as increasing the bandwidth for next-generation intelligent computing.
Tropical Storm Tapah has a huge "tail" on NASA satellite imagery. NASA's Terra satellite captured an image of the northwestern Pacific Ocean storm that revealed a large band of thunderstorms that resemble a large tail. The NASA imagery also indicated that the storm is getting better organized.
