Despite the remarkable success of molecular targeted therapy in recent years, the rapid increase of drug resistance is a major obstacle to effective treatment of lung cancer.
How do lung cancer cells adapt to targeted therapy? What is the molecular basis of such adaptive behavior? Can this adaptive response be memorized by cancer cells? If so, is it heritable? The answers to these questions will provide a deeper understanding of the evolutionary process of drug resistance during molecular targeted therapy.
Tooth decay is among the costliest and most widespread bacterial diseases. Virulent bacteria cause the acidification of tooth enamel and dentin, which, in turn, causes secondary tooth decay.
WASHINGTON (July 9, 2019) -- Sun safety practices for attendees at skin cancer screening events differ from the general public, according to findings published by researchers from the George Washington University (GW) Cancer Center. The study was published in the Journal of Drugs in Dermatology.
Research published in this week's issue of Nature Communications reveals a considerable chance for an ice-free Arctic Ocean at global warming limits stipulated in the Paris Agreement. Scientists from South Korea, Australia and the USA used results from climate models and a new statistical approach to calculate the likelihood for Arctic sea ice to disappear at different warming levels.
Fluctuations in the masses of the world's largest ice sheets carry important consequences for future sea level rise, but understanding the complicated interplay of atmospheric conditions, snowfall input and melting processes has never been easy to measure due to the sheer size and remoteness inherent to glacial landscapes.
UC Riverside scientists have decoded the genome of black-eyed peas, offering hope for feeding Earth's expanding population, especially as the climate changes.
Understanding the genes responsible for the peas' drought and heat tolerance eventually could help make other crops tougher too.
Tropical Storm Cosme formed in the Eastern Pacific Ocean over the weekend of July 6 and 7 and after two days, the storm already weakened to a remnant low pressure area. NASA's Aqua satellite found the storm devoid of strong thunderstorms and appeared as a wispy ring of clouds.

Grandparents have long been associated with letting their grandchildren do things their parents would never permit. Candy. Extended bedtime. Too much television. Carefree fun. They like to spoil their grandchildren.
A new study by Rutgers and other researchers finds that today's grandparents are still true to their traditional fun-loving image -- allowing their grandchildren, while under their supervision, to spend about half of their time on a mobile phone, tablet, computer or TV.
An unprecedented belt of brown algae stretches from West Africa to the Gulf of Mexico--and it's likely here to stay. Scientists at the University of South Florida in St. Petersburg's College of Marine Science used NASA satellite observations to discover and document the largest bloom of macroalgae in the world, dubbed the Great Atlantic Sargassum Belt, as reported in Science.
Three researchers at The University of Texas at Arlington have made a groundbreaking discovery that could enhance the ability of reef-building corals to survive a rapidly warming and disease-filled ocean.
In a newly published paper in Proceedings of the Royal Society, Bradford Dimos, Laura Mydlarz and Mark Pellegrino, all from the Department of Biology in the College of Science, report their identification of a mitochondrial unfolded protein response in an endangered coral species.
Racial residential segregation is the predominant factor that explains why some cities have greater racial disparities in fatal police shootings than others, according to a new study by Boston University School of Public Health (BUSPH) researchers published in the Journal of the National Medical Association.
ITHACA, N.Y. - A breakthrough imaging technique developed by Cornell University researchers shows promise in decontaminating water by yielding surprising and important information about catalyst particles that can't be obtained any other way.
Travelling abroad for the summer can change a person's perspective--and it can also change the makeup of his gut.
A San Diego State University researcher has found evidence that a virus nicknamed crAssphage, found in the guts of about 70 percent of the world's population, has a country-specific biomarker that changes rapidly as humans travel from one location to another.
For the first time, scientists have captured high-resolution, three-dimensional images of an enzyme in the process of precisely cutting DNA strands.
The images--captured using a technique called cryogenic electron microscopy, or cryo-EM--reveal new information about how a gene-editing tool called CRISPR-Cas9 works, which may help researchers develop versions of it that operate more efficiently and precisely to alter targeted genes.
Dates are one of the most significant fruit crops grown in the Middle East; however, little is known about how these resilient palm trees flourish in the high temperatures of desert habitats. Now, KAUST researchers have shown that date palms, after germination, can pause their early development within womb-like root structures in the soil, ready to grow when the environmental conditions are just right.
