In a time of a global crisis such as the ongoing COVID-19 pandemic, it is easy to note how people move through different phases to buckle up for such unprecedented and arduous times.
In cancer, a lot of biology goes awry: Genes mutate, molecular processes change dramatically, and cells proliferate uncontrollably to form entirely new tissues that we call tumors. Multiple things go wrong at different levels, and this complexity is partly what makes cancer so difficult to research and treat.
So it stands to reason that cancer researchers focus their attention where all cancers begin: the genome. If we can understand what happens at the level of DNA, then we can perhaps one day not just treat but even prevent cancers altogether.
COLUMBUS, Ohio - The symptoms of grief people feel for a loved one facing a life-limiting illness fluctuate over time, a new study found - suggesting that individuals can adjust to their emotional pain, but also revealing factors that can make pre-loss grief more severe.
Researchers examined changes in the severity of pre-loss grief symptoms in people whose family members had either advanced cancer or dementia.
NEW YORK, NY (May 10, 2021)--Scientists have discovered that many esophageal cancers turn on ancient viral DNA that was embedded in our genome hundreds of millions of years ago.
"It was surprising," says Adam Bass, MD, the Herbert and Florence Irving Professor of Medicine at Columbia University Vagelos College of Physicians and Surgeons and Herbert Irving Comprehensive Cancer Center, who led the study published May 10 in Nature Genetics.
Due to their complexity and microscopic scale, plant-microbe interactions can be quite elusive. Each researcher focuses on a piece of the interaction, and it is hard to find all the pieces let alone assemble them into a comprehensive map to find the hidden treasures within the plant microbiome. This is the purpose of review, to take all the pieces from all the different sources and put them together into something comprehensive that can guide researchers to hidden clues and new associations that unlock the secrets of a system.
Berkeley -- Forests' ability to survive and adapt to the disruptions wrought by climate change may depend, in part, on the eddies and swirls of global wind currents, suggests a new study by researchers at the University of California, Berkeley.
Imaging technology has come a long way since the beginning of photography in the mid-19th century. Now, many state-of-the-art cameras for demanding applications rely on mechanisms that are considerably different from those in consumer-oriented devices. One of these cameras employs what is known as "single-photon imaging," which can produce vastly superior results in dark conditions and fast dynamic scenes. But how does single-photon imaging differ from conventional imaging?
Peptides " short strings of amino acids" play a vital role in health and industry with a huge range of medical uses including in antibiotics, anti-inflammatory and anti-cancer drugs. They are also used in the cosmetics industry and for enhancing athletic performance. Altering the structure of natural peptides to produce improved compounds is therefore of great interest to scientists and industry. But how the machineries that produce these peptides work still isn't clearly understood.
Despite our remarkable advances in medicine and healthcare, the cure to cancer continues to elude us. On the bright side, we have made considerable progress in detecting several cancers in earlier stages, allowing doctors to provide treatments that increase long-term survival. The credit for this is due to "integrated diagnosis," an approach to patient care that combines molecular information and medical imaging data to diagnose the cancer type and, eventually, predict treatment outcomes.
HOUSTON - (May 10, 2021) - Implants that require a steady source of power but don't need wires are an idea whose time has come.
Now, for therapies that require multiple, coordinated stimulation implants, their timing has come as well.
Rice University engineers who developed implants for electrical stimulation in patients with spinal cord injuries have advanced their technique to power and program multisite biostimulators from a single transmitter.
According to the International Whaling Commission, whale-watching tourism generates more than $2.5 billion a year. After the COVID-19 pandemic, this relatively safe outdoor activity is expected to rebound. Two new studies funded by a collaborative initiative between the Smithsonian Tropical Research Institute (STRI) in Panama and Arizona State University (ASU) show how science can contribute to whale watching practices that ensure the conservation and safety of whales and dolphins.
In a newly published paper, Virginia Tech geoscientists have found that shallow wastewater injection -- not deep wastewater injections -- can drive widespread deep earthquake activity in unconventional oil and gas production fields.
Your local city park may be improving your health, according to a new paper led by Stanford University researchers. The research, published in Proceedings of the National Academy of Sciences, lays out how access to nature increases people's physical activity - and therefore overall health - in cities. Lack of physical activity in the U.S.
Conducting a discussion in a noisy place can be challenging when other conversations and background noises interfere with our ability to focus attention on our conversation partner. How the brain deals with the abundance of sounds in our environments, and prioritizes among them, has been a topic of debate among cognitive neuroscientists for many decades.
All three species of manatee now present on Earth share a common ancestor from which they split some 6.5 million years ago, when a huge lake in Amazonia, then linked to the Caribbean, was cut off from the sea. The African manatee Trichechus senegalensis is not as genetically close to the West Indian manatee T. manatus as was thought, and adaptation to this complex environment by the Amazonian manatee T. inunguis has left at least one mark in its genetic code.
