Most ovarian cancer starts in fallopian tubes. Then it sloughs from its site of origin and floats around in fluid until finding new sites of attachment. It's not easy for cancer cells to survive away from their moorings. Observations by ovarian cancer doctors at University of Colorado Cancer Center and elsewhere hint at how they might do it: These doctors have seen that ovarian cancer cells often collect in tissues with high fat content. Could these cells be somehow using fat to survive the journey from their point of origin to their sites of growth?
ITHACA, N.Y. - Cornell University astronomers have created five models representing key points from our planet's evolution, like chemical snapshots through Earth's own geologic epochs.
The models will be spectral templates for astronomers to use in the approaching new era of powerful telescopes, and in the hunt for Earth-like planets in distant solar systems.
The cerebral cortex is the relatively thin, folded, outer "gray matter" layer of the brain crucial for thinking, information processing, memory, and attention. Not much has been revealed about the genetic underpinnings that influence the size of the cortex's surface area and its thickness, both of which have previously been linked to various psychiatric traits, including schizophrenia, bipolar disorder, depression, attention deficit hyperactivity disorder (ADHD), and autism.
AURORA, Colo. (March 26, 2020) - Assessing adverse childhood experiences and current anxiety and depression symptoms may help ease cognitive distress in women who have undergone a surgical menopause for cancer risk-reduction, or RRSO, according to a new study published in Menopause.
Recent research by Rafael C. Bernardi at the University of Illinois, Urbana-Champaign examines why a common tool in biotechnology -- the binding of streptavidin to biotin -- shows different mechanical resilience in different research labs.
Highly focused, intense doses of radiation called stereotactic ablative radiation (SABR) may slow progression of disease in a subset of men with hormone-sensitive prostate cancers that have spread to a few separate sites in the body, according to results of a phase II clinical trial of the therapy.
MADISON, Wis. -- Removing a gene from the cells that produce insulin prevents mice from developing Type 1 diabetes by sparing the cells an attack from their own immune system, a new UW-Madison study shows.
The cellular sleight-of-hand may suggest ways to prevent Type 1 diabetes in high-risk individuals, as well as other diseases in which the immune system targets the body's own cells.
What The Study Did: Head congestion is one of the most common symptoms experienced by astronauts during spaceflight. This observational study examined preflight and postflight head magnetic resonance images (MRIs) of 35 astronauts who participated in either a short-duration (30 days or less) Space Shuttle mission or a long-duration (greater than 30 days) International Space Station mission.
How the novel coronavirus that causes COVID-19 made the leap from animals to humans is a puzzle that scientists are trying to solve as humanity comes to grip with the deadly pandemic sweeping the globe.
At the frontline of this scientific work is Professor Edward Holmes, an evolutionary virologist who holds a joint position with the School of Life and Environmental Sciences and the School of Medical Sciences at the University of Sydney.
BOSTON - It's now accepted that gut-barrier dysfunction and gut-derived chronic inflammation play a role in human aging, but how that process is regulated is still largely a mystery. A team led by Richard Hodin, MD, chief of the Division of General and Gastrointestinal Surgery at Massachusetts General Hospital (MGH) has uncovered an important piece of the puzzle which is described in the journal JCI Insight.
What The Study Did: This study examined the medical records of 33 newborns born to women with COVID-19.

Ependymoma is a rare form of brain cancer that implicates children and is often tricky to diagnose. Since effective treatment options can be initiated only after a well-formed diagnosis, there is a dire need among the medical community to identify markers for ependymoma, which in turn, will help oncologists tailor therapy better. Richard Wong's and Mitsutoshi Nakada's team at Kanazawa University has now shown how one gene closely linked to ependymoma can help with not just diagnosis, but also treatment options for the condition.
People say life gets better with age. Now research suggests this may be because older people have the wisdom and time to use mindfulness as a means to improve wellbeing.
Healthy ageing researchers at Flinders University say certain characteristics of mindfulness seem more strongly evident in older people compared to younger people - and suggest ways for all ages to benefit.
Although the overall prevalence of overweight and obesity in children and adolescents has fallen slightly over the past decade, the rates of both conditions have increased in the most disadvantaged neighbourhoods. This is the conclusion of a new study based on data from more than one million children in Catalonia, which was carried out by the Barcelona Institute for Global Health (ISGlobal) --a centre supported by "la Caixa"-- and the IDIAPJGol Institute.
Our body's ability to detect disease, foreign material, and the location of food sources and toxins is all determined by a cocktail of chemicals that surround our cells, as well as our cells' ability to 'read' these chemicals. Cells are highly sensitive. In fact, our immune system can be triggered by the presence of just one foreign molecule or ion. Yet researchers don't know how cells achieve this level of sensitivity.
