Pulmonary malignancy is one of the most frequent and fatal cancers in older patients. Studies have shown that lung cancer patients have a high incidence of lower respiratory tract infections. This is due to the fact that these patients usually have airway obstruction, sticky sputum that is not easy to cough up, destruction of mucosal surfaces, and treatment with radiotherapy and chemotherapy. When most patients are found to have lung cancer, they have already developed distal metastasis and lost the chance of surgery, therefore, they usually choose to be treated with radiotherapy, chemotherapy, and targeted drugs. Radiotherapy and chemotherapy ...

Researchers at the University of Queensland have revealed the crucial role of saturated fatty acids in the brain’s consolidation of memories.  Dr Isaac Akefe from UQ’s Queensland Brain Institute has uncovered the molecular mechanism and identified the genes underlying the memory creation process, opening the door to a potential treatment for neurodegenerative disorders.  “We’ve shown previously that levels of saturated fatty acids increase in the brain during neuronal communication, but we ...

A Doppler ultrasound that measures the blood flow of small unborn babies can reveal whether or not the placenta is working properly. In case of repeated deviations from these Doppler measurements, additional monitoring of the unborn baby is necessary. These deviations indicate a higher risk of oxygen deficiency and other health problems for the baby. This study by Amsterdam UMC in collaboration with UMC Groningen and 17 other Dutch hospitals is published today in the British Journal of Obstetrics & Gynaecology.  Around 10% of unborn babies are classed as small for ...

A new species of pterosaur from specimens found on the Isle of Skye, Scotland, has been announced by scientists from the Natural History Museum, University of Bristol, University of Leicester, and University of Liverpool. The new pterosaur is part of the Darwinoptera clade of pterosaurs. Its discovery shows that the clade was considerably more diverse than previously thought, and persisted for more than 25 million years, from the late Early Jurassic to the latest Jurassic. During this period species within the clade spread worldwide. The discovery underpins a new and more complex model for the early evolution of pterosaurs. The rarity of Middle Jurassic pterosaur ...

The influence of online vote advice tools designed to help voters discover more about candidates is limited when elections are affected by authoritarianism, a new study shows. Voting advice applications offer voters nonpartisan information about political parties, candidates, and policy issues. The research shows they could be an alternative source of information for those interested in learning about politics in democracies, but their use would be limited in authoritarian settings, particularly in the longer term. In the short-term, and during highly competitive elections with tiny winning margins for candidates ...

A million years ago, the oldest known species to walk upright like a human, the Homo Erectus, had a human-like fascination with crystals. Historians can even pin down the possible reasons – crystals didn’t look like anything around at the time - trees, valleys, mountains. Crystals were a material to ponder, a fascinating diversion for the mind.   To this day, the human preoccupation with the magic of crystals continues to fill the mind’s eye of scientists who have developed ways to use crystals for everything from malaria cures to solar cells and semiconductors, catalysts and optical elements. Over the years crystals have become crucial constituents ...

A multi-disciplinary research team specializing in canine behavior and Artificial Intelligence has developed an AI algorithm that automates the high-stakes process of evaluating potential working dogs’ personalities. They hope to help dog training agencies more quickly and accurately assess which animals are likely to succeed long term in careers such as aiding law enforcement and assisting persons with disabilities. The personality test could also be used for dog-human matchmaking, helping shelters with proper placement, thus reducing the number of animals returned ...

– By Linda Vu For more than 50 years, the National Hurricane Center has used the Saffir-Simpson Windscale to communicate the risk of property damage; it labels a hurricane on a scale from Category 1 (wind speeds between 74 - 95 mph) to Category 5 (wind speeds of 158 mph or greater). But as increasing ocean temperatures contribute to ever more intense and destructive hurricanes, climate scientists Michael Wehner of Lawrence Berkeley National Laboratory (Berkeley Lab) and James Kossin of the First Street Foundation wondered whether the ...

People with depression have higher body temperatures, suggesting there could be a mental health benefit to lowering the temperatures of those with the disorder, a new UC San Francisco-led study found. The study, publishing today in Scientific Reports, doesn’t indicate whether depression raises body temperature or a higher temperature causes depression. It’s also unknown whether the higher body temperature observed in people with depression reflects decreased ability to self-cool, increased generation of heat from metabolic processes or a combination of both.  Researchers analyzed data from more than 20,000 international ...

COLUMBUS, Ohio – White Americans are more likely than Black and Hispanic people in the United States to experience “deaths of despair” even though they are less likely to suffer from severe psychological distress, a new study finds.   The results suggest that, for some reason, whites are more vulnerable to the damaging effects of psychological distress than Blacks or Hispanics, said Hui Zheng, lead author of the study and professor of sociology at The Ohio State University. Zheng is currently on leave at the University of Hong Kong.   “The white population has an increasing trend of despair-related mortality after 2000,” Zheng said. ...

EVANSTON, Ill. — When carbon molecules from plants enter the soil, they hit a definitive fork in the road. Either the carbon gets trapped in the soil for days or even years, where it is effectively sequestered from immediately entering the atmosphere. Or it feeds microbes, which then respire carbon dioxide (CO2) into the ever-warming environment. In a new study, Northwestern University researchers determined the factors that could tip plant-based organic matter in one direction or the other.  By combining laboratory experiments and molecular modeling, researchers ...

Climate change is already harming agricultural yields and may one day pose a significant threat to the world’s food supply. Engineering more resilient crops, including those able to thrive in the face of drought or high soil salinity levels, is an increasingly urgent need. A new study from the Keck School of Medicine of USC, funded in part by the National Institutes of Health, reveals details about how plants regulate their responses to stress that may prove crucial to those efforts. Researchers found that plants use their circadian clocks to respond to changes in external water and salt levels throughout the day. That same circuitry—an ...

Methods commonly used to measure poverty can lead to vastly different conclusions about who actually lives in poverty, according to a new Stanford University-led study. Based on household surveys in sub-Saharan Africa, the first-of-its-kind analysis, published Feb. 5 in Proceedings of the National Academy of Sciences, underscores the importance of accurately defining and measuring poverty. Its findings could help inform how governments, nonprofit organizations, and international development agencies allocate resources and evaluate the effectiveness of poverty-alleviation policies around the world. “They say you can’t manage what ...
