Scientists have discovered how some cancer cells survive treatment and cause cancer to recur, along with a potential way to stop the process.

A new methodology predicts disease transmission from wildlife to humans, from one wildlife species to another and determines who is at risk of infection.
High levels of hydroxyl radicals (OH) can be generated indoors, simply due to the presence of people and ozone.
Researchers have examined how social and economic factors, such as level of education and general knowledge of Ebola, might contribute to 'high-risk behaviors' that may bring individuals into contact with potentially infected animals. A focus on geographical locations with high concentrations of individuals at high-risk could help public health officials better target prevention and education...
Astronomers using the VLBA have produced a full, 3-D view of a binary star system with a planet orbiting one of the stars. Their achievement promises important new insights into the process of planet formation.
Scientists have managed to generate a new type of human cell in the lab using stem cells. The new cells closely resemble their natural counterparts in early human embryos. As a result, researchers can now better study what happens just after an embryo implants in the womb.
A market-led approach could be key to guiding policy, research and business decisions about future climate risks, a new study outlines. Now that organizations appreciate how essential it is to consider climate risks within their strategic plans, the pressing need for forward-looking, reliable information is growing. However, researchers say current climate-risk forecasts that guide key business...
About 30,000 cases of lung cancer occur in Spain each year. Mutations in KRAS oncogenes account for 10-15% of these cases, a subgroup against which there are still no effective therapies. Researchers have succeeded in determining the structure of the RAF1 protein, a therapeutic target against cancers associated with KRAS oncogenes.
With an eye toward a possible return mission years in the future, Cornell University astronomers have shown how smooth terrains -- a good place to land a spacecraft and to scoop up samples -- evolve on the icy world of comets.
Two vaccine doses provide only limited and short-lived protection against SARS-CoV-2 infection with the Omicron variant. A new study suggests that a third COVID-19 vaccine dose increased the level and duration of protection against Omicron infection and hospitalization.
An insulin-suppressing protein may be the fountain of youth for ants and provides clues about aging in other species, according to a new study.
Researchers have developed a new method to identify people who are at greater genetic risk of developing Alzheimer's disease, before any symptoms appear -- which could help speed creation of novel treatments.
Scientists have tested the efficacy of GnRH injection therapy in order to improve the cognitive functions of a small group of patients with Down syndrome. First the scientists revealed a dysfunction of the GnRH neurons in an animal model of Down syndrome and its impacts on the cognitive function impairment associated with the condition. Then a pilot study testing GnRH pulsatile injection therapy...
A new study of more than 8 million children in Nordic countries suggests the possibility that children born after use of a fertility procedure known as frozen-thawed embryo transfer may have a higher risk of cancer than children born through other means.
A Policy Forum article calls for a new approach to regulating genetically engineered (GE) crops, arguing that current approaches for triggering safety testing vary dramatically among countries and generally lack scientific merit -- particularly as advances in crop breeding have blurred the lines between conventional breeding and genetic engineering.
Researchers quantify the risk to forests from climate change along three dimensions: carbon storage, biodiversity and forest loss from disturbance, such as fire or drought. The results show forests in some regions experiencing clear and consistent risks. In other regions, the risk profile is less clear, because different approaches that account for disparate aspects of climate risk yield diverging...
Robots can be better at detecting mental wellbeing issues in children than parent-reported or self-reported testing, a new study suggests.
Researchers have published results that show encouraging therapeutic options for patients with the blood cancer multiple myeloma after first-line treatment with bispecific antibodies fails. Bispecific antibodies are a type of antibody that can bind to two different antigens at the same time -- they are meant to enhance the immune system's destruction of tumor cells.
Estuaries are one of the most valuable biomes on Earth, and megafires -- like Australia's 2019/20 Black Summer fires -- represent an emerging threat to estuarine and coastal ecosystems, with the extent and proximity of the wildfire influencing the impact on estuaries.
New findings have demonstrated a molecular link between COVID-19 and serotonin cells in the gut. The research could help provide further clues to what could be driving COVID-19 infection and disease severity and supports previous evidence that antidepressants, known as selective serotonin reuptake inhibitors (SSRIs), could reduce the severity of COVID symptoms.
A new study reveals how a rare genetic mutation leads to intellectual disability. The P212L mutation in an enzyme called CaMKIIalpha, which is important for learning and memory, is known to be linked to intellectual disability. However, the exact process by which the mutation affected the enzyme's activity was unclear, until now.
Scientists studying mice from the Andes Mountains in Patagonia noticed something they couldn't explain: the mice from the western side of the mountains were bigger than the ones from the east, but DNA said that they were all from the same species. The researchers examined the skulls of 450 mice from the southern tip of South America, and found that existing biological laws didn't explain the size...
Overweight increases the risk of an imbalance in sugar metabolism and even of diabetes. A research group has now shown the opposite is true as well: deficits in the body's insulin production contribute to overweight.
It might sound weird, but it's true: the steppes of Eastern Europe are home to a similar number of plant species as the regions of the Amazon rainforest. However, this is only apparent when species are counted in small sampling areas, rather than hectares of land.
Global fish stocks will not be able to recover to sustainable levels without strong actions to mitigate climate change, a new study has projected. Researchers projected the impact that different global temperature increases and ranges of fishing activity would have on biomass, or the amount of fish by weight in a given area, from 1950 to 2100. Their simulations suggest that climate change has...
