Tucson, Ariz. (March 16, 2021) - This week, a new, peer-reviewed scientific study finds that there is far more potential jaguar habitat in the U.S. than was previously thought. Scientists identified an area of more than 20 million acres that could support jaguars in the U.S., 27 times the size of designated critical habitat.
An estimated 14,480 new cases of invasive cervical cancer will be diagnosed in the United States this year, according to the American Cancer Society. Cases that could be prevented or cured with better education from screening to treatment based on improved provider-patient communication, says a Michigan State University researcher.
Increased global temperatures help invasive species establish themselves in ecosystems, new research led by a Swansea University bioscientist has shown.
The study, published by the Royal Society, gives an insight into the probable combined effects of species invasions, which are becoming more common, and global warming.
Climate warming and biological invasions result in the loss of species. They also alter the structure of ecosystems and the ways in which species interact.
Information on individuals' mobility--where they go as measured by their smartphones--has been used widely in devising and evaluating ways to respond to COVID-19, including how to target public health resources. Yet little attention has been paid to how reliable these data are and what sorts of demographic bias they possess. A new study tested the reliability and bias of widely used mobility data, finding that older and non-White voters are less likely to be captured by these data.
Oncotarget published "Genomic and neoantigen evolution from primary tumor to first metastases in head and neck squamous cell carcinoma" which reported that prior work has characterized changes in the mutation burden between primary and recurrent tumors; however, little work has characterized the changes in neoantigen evolution.
GRAND RAPIDS, Mich. (March 16, 2021) -- Older age at the time of conception and alcohol consumption during pregnancy have long been known to impact fetal development.
Now, a new report published in Proceedings of the National Academy of Sciences suggests older age and alcohol consumption in the year leading up to conception also may have an impact by epigenetically altering a specific gene during development of human eggs, or oocytes.
Bottlenose dolphins learn to cope with coastal construction activities. That is the conclusion of a study published in Frontiers in Marine Science. The study is the first to provide a longitudinal perspective on the cumulative impacts of coastal construction.
A new study in Behavioral Ecology, published by Oxford University Press, finds that women are less likely to procreate in urban areas that have a higher percentage of females than males in the population.
The results, published in the renowned scientific journal The Cryosphere, have made it possible to reliably describe snow trends at up to 2000 metres above sea level. Higher than that, there are too few measuring stations to be able to extract reliable information for the entire Alpine region. This consistent data set spans five decades and was created through the collaboration of more than 30 scientists from each of the Alpine states. The results and data collected represent a valuable aid for future studies, especially those which centre on climate change.
As their name suggests, by-the-wind sailor jellyfish know how to catch a breeze. Using a stiff, translucent sail propped an inch above the surface of the ocean, these teacup-sized organisms skim along the water dangling a fringe of delicate purple tentacles just below the surface to capture zooplankton and larval fish as they travel.
A 2020 explosion in Lebanon's port city of Beirut led to a southward-bound, high-velocity atmospheric wave that rivaled ones generated by volcanic eruptions.
Just after 6 p.m. local time (15.00 UTC) on August 4, 2020, more than 2,750 tons worth of unsafely stored ammonium nitrate exploded in Lebanon's port city of Beirut, killing around 200 people, making more than 300,000 temporarily homeless, and leaving a 140-metre-diameter crater in its wake. The blast is considered one of the most powerful non-nuclear, man-made explosions in human history.
PHILADEPHIA - Since the 1990s the rate of spinal fusion to treat lower back pain has been on the rise. A new prospective clinical study published in the journal Neurosurgery, the official journal of the Congress of Neurological Surgeons, found that lumbar fusions were three times more likely to be effective and obtain better patient outcomes, when guidelines for fusion were followed.
Fields and farms with more variety of insect pollinator species provide more stable pollination services to nearby crops year on year, according to the first study of its kind.
An international team of scientists led by the University of Reading carried out the first ever study of pollinator species stability over multiple years across locations all around the world, to investigate how to reduce fluctuations in crop pollination over time.
Scientists at Sanford Burnham Prebys Medical Discovery Institute demonstrated for the first time that blocking "cell drinking," or macropinocytosis, in the thick tissue surrounding a pancreatic tumor slowed tumor growth--providing more evidence that macropinocytosis is a driver of pancreatic cancer growth and is an important therapeutic target.
Our immune system is very successful when it comes to warding off viruses and bacteria. It also recognizes cancer cells as potential enemies and fights them. However, cancer cells have developed strategies to evade surveillance by the immune system and to prevent immune response.
