Johns Hopkins Medicine researchers have created a computer program for scientists at no charge that lets users readily quantify the structural and functional changes in the blood flow networks feeding tumors.
The researchers published a link to download the new program, called HemoSYS, and an accompanying manual with instructions on how to use it, on Feb. 11 in Scientific Reports.
For wildlife, cities can present new opportunities as well as threats. Researchers from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) and the Luxembourg National Museum of Natural History (NMNH) analysed genetic material of red foxes (Vulpes vulpes) inhabiting Berlin and its surroundings. They identified two genetically distinct, adjacent "urban" and "rural" fox populations and revealed that physical barriers such as rivers or man-made structures reduce the exchange between these populations but also differences in human activity in these landscapes play a major role.
The study is based on the results obtained in the Digital Mammography (DM) DREAM Challenge, an international competition led by IBM where researchers from the Instituto de Física Corpuscular (IFIC, CSIC-UV) have participated along with scientists from the UPV's Institute of Telecommunications and Multimedia Applications (iTEAM).
DUARTE, Calif. -- A $12 million federal grant enabled City of Hope and collaborators to deploy a novel cloud-computing platform, making an immense amount of data from a historic 25-year study more accessible and user-friendly.
As the power of extreme weather events increase with climate change, a team of scientists warn that lakes around the world may dramatically change, threatening ecosystem health and water quality.
And the international team reports that our limited understanding of how lakes--especially algae at the base of food webs--may respond to more-extreme storms represents a knowledge gap that increases the risk.
Understanding the impacts of climate change on fish communities is an important piece of navigating the future, but it's difficult to tease out the individual factors at play in natural systems. This makes it hard for researchers to fully understand how climate change will affect the diversity and abundance of fishes in the future.
To stop the spread of disease, it could be used to coat phone screens and keyboards, as well as the inside of catheters and breathing tubes, which are a major source of healthcare-associated infections (HCAIs).
March 5, 2020--ATLANTA-- The burden of colorectal cancer is swiftly shifting to younger individuals as incidence increases in young adults and declines in older age groups, according to the latest edition of Colorectal Cancer Statistics 2020, a publication of the American Cancer Society. A sign of the shift: the median age of diagnosis has dropped from age 72 in 2001-2002 to 66 during 2015-2016; in other words, half of all new diagnoses are now in people 66 or younger.
Bioengineers at the University of California San Diego have redesigned how harmless E. coli bacteria "talk" to each other. The new genetic circuit could become a useful new tool for synthetic biologists who, as a field, are looking for ways to better control the bacteria they engineer to perform all sorts of tasks, including drug delivery, bioproduction of valuable compounds, and environmental sensing.
Scientists at Uppsala University have proposed an addition to the theory of evolution that can explain how and why genes move on chromosomes. The hypothesis, called the SNAP Hypothesis, is presented in the scientific journal PLOS Genetics.
Wetlands, floodplains and aquatic habitats are some of Utah's most important ecosystems. They are home to many bird, plant and fish species, and they provide unique outdoor recreation opportunities.
But in recent years these habitats have faced mounting pressure from encroaching land use and increased demand for water. Now researchers at Utah State University are developing new tools that help preserve and increase the area and quality of wetland, floodplain and aquatic habitats.
The cover for issue 9 of Oncotarget features Figure 6, "BCL6 knock-out in a DLBCL xenograft induces tumor stasis," by Schlager, et al.
DALLAS - March 4, 2020 - Integrating travel history information into routine medical assessments could help stem the rapidly widening COVID-19 epidemic, as well as future pandemics, infectious disease specialists recommend in the Annals of Internal Medicine.
NASA's Aqua satellite continues to provide forecasters with a visible image ex-tropical cyclone Esther's remnant clouds and storms, now over the Barkly Region of Australia's Northern Territory.
On March 4, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Aqua satellite provided a visible image of Esther's remnant clouds that showed the center over the Barkly region of the Northern Territory.
According to popular theory, men live shorter lives than women because they take bigger risks, have more dangerous jobs, drink and smoke more, and are poor at seeking advice from doctors.
But research by scientists at UNSW Sydney suggests the real reason may be less related to human behaviour and more to do with the type of sex chromosomes we share with most animal species.
