A new approach to better select breast cancer patients in need of urgent surgery or chemotherapy during the COVID-19 pandemic has been developed by researchers at The Royal Marsden and the Breast Cancer Now Research Centre at The Institute of Cancer Research, London, in collaboration with colleagues in the UK, Germany and US.
Obesity affects more than 40 percent of adults in the United States and 13 percent of the global population. With obesity comes a variety of other interconnected diseases including cardiovascular disease, diabetes, and fatty liver disease, which makes the disease one of the most difficult - and most crucial - to treat.
Scientists have found that a specific type of ovarian cancer could possibly benefit from existing platinum-based chemotherapy and new DNA repairing treatments, following better testing.
Integrating nanomaterial with light-absorbing molecule powers hydrogen production from water and sun
In line with the depletion of fossil fuels and the environmental problems our planet faces due to their combustion, developing technology for clean energy generation is a topic of global interest. Among the various methods proposed to generate clean energy, photocatalytic water splitting is showing much promise. This method utilizes solar energy to split water (H2O) molecules and obtain dihydrogen (H2). The H2 can then be used as a carbon-free fuel or as raw material in the production of many important chemicals.
Spectroscopy has roots in early 19th century curiosity about interactions between matter and electromagnetic radiation. Thanks to advances in electronics and materials science, various spectroscopy techniques are now routinely used to study the composition of materials and the nature of their chemical bonds by analyzing how they absorb or reflect electromagnetic waves.
The East African Rift System (EARS) is a newly forming plate tectonic boundary at which the African continent is being separated into several plates. This is not a clean break. The system includes several rift arms and one or more smaller so-called microplates. According to GPS data, the Victoria microplate is moving in a counterclockwise rotation relative to Africa in contrast to the other plates involved.
Scientists at Sanford Burnham Prebys Medical Discovery Institute have shown that pancreatic cancer metastasis--when tumor cells gain the deadly ability to migrate to new parts of the body--can be suppressed by inhibiting a protein called Slug that regulates cell movement.
An international research team, led by Monash University and ANSTO (Australia's Nuclear Science and Technology Organisation), has created an ultrathin membrane with high porosity that can filter potentially harmful ions from water.
Researchers created this ultrathin molecular sieve membrane using 2D nanosheets, developed with water-stable Metal Organic Frameworks (MOFs).
The membrane has potential to deliver clean water for millions of people globally through purification and desalination processes. It can also be used in the separation of gases and solvents.
Bright pink flamingos are more aggressive than paler rivals when fighting over food, new research shows.
Pink plumage is a sign of good health in lesser flamingos, and a flush of colour often means they are ready to breed.
So when the birds squabble over food, the pinkest flamingos - both male and female - tend to push the others around.
A shortage of summer nutrients as a result of our changing climate has contributed to a 50% decline in important North East Atlantic plankton over the past 60 years.
New research, published in Global Change Biology, shows that larger, nutritious plankton - vital to support fish, seabirds and marine mammals - are being replaced by tiny, primary producers that are of poorer food quality.
Philadelphia, June 8, 2020 - Engaging in family meals may be a matter of improving communication and support at home. A new study in the Journal of Nutrition Education and Behavior, published by Elsevier, connects less family discouragement and better family communication with a higher likelihood to eat evening family meals and family breakfasts together, and not in front of a television.
Asking elderly patients how much they exercise can help predict their risk of heart disease and death, Mount Sinai and collaborative researchers say. Their study, published in the Monday, June 5, issue of Mayo Clinic Proceedings: Innovations, Quality and Outcomes shows that a simple assessment of exercise activity during appointments for atherosclerosis screening can lead to earlier interventions and ultimately improve care among this population.
The increasing popularity of direct to consumer (DTC) genetic testing is having an impact on clinical genetics services, according to Australian researchers who will present their work to the 53rd annual conference of the European Society of Human Genetics, being held entirely on-line due to the Covid-19 pandemic, today [Saturday]. Many consumers are unsure about what to do with the results they receive, and many general practitioners are ill-equipped to advise them, meaning that they turn to clinical genetics services for help.
What The Study Did: This survey study looked at the association between starting to use flavored or unflavored e-cigarettes and subsequently starting or quitting smoking among adolescents and adults.
Authors: Abigail S. Friedman, Ph.D., of the Yale School of Public Health in New Haven, Connecticut, is the corresponding author.

A research team lead by Ryusuke Futamura of Shinshu University investigated the response of magnetic ionic liquids (MIL) to magnetic fields from the microscopic view points. Magnetic fluids, which can respond to magnetic fields, can be made by dispersing ferromagnetic nanoparticles in a solvent. Some pure liquids that are not mixtures also respond to magnetic feilds. For example, oxygen is a liquid around -200°C and is attracted to magnets. In this study, pure magnetic ionic liquids Emim[FeCl4] and Bmim[FeCl4] were examined in the microscopic scale.
