Culture
Infidelity is one of the most common reasons that heterosexual couples break up. Researchers who have studied 160 different cultures find this to be true worldwide.
However, men and women look at different types of infidelity differently.
Men usually regard physical infidelity - when the partner has sex with another person - more seriously than women do.
Women regard emotional infidelity - when the partner initiates a close relationship with another person - as more serious.
"In this paper we show that supporting Indigenous peoples' rights is in the interest of the conservation agenda," explains Dr. Álvaro Fernández-Llamazares, the first author of the study, from the University of Helsinki. "The future of a substantial proportion of the Amazon's biodiversity depends largely on coordinated action to support and strengthen Indigenous peoples' rights across the entire region."
A new study from Trinity College Dublin highlights that fitness may be a more important clinical endpoint for improvement in patients with fatty liver diseases during exercise trials, rather than weight loss. The findings have been published today (Tuesday, 28th July 2020) in the medical journal Alimentary Pharmacology and Therapeutics.
Metabolic associated fatty liver disease (MAFLD) is a condition characterised by a build up of fat in the liver. The liver is central to a suite of vital processes in the body including digestion, blood clotting and energy production.
Skoltech researchers and their colleagues from Aalto University have discovered that electrochemical doping with ionic liquid can significantly enhance the optical and electrical properties of transparent conductors made of single-walled carbon nanotube films. The results were published in the journal Carbon.
Coccidiosis is a kind of intestinal illness that affects different groups of animals. It inhibits the absorption of nutrients and growth so that, at times, the animal dies, thus producing financial losses in the livestock industry. In order to fight this disease, antibiotics like coccidiostats are prescribed, which are effective drugs in treating the illness but that also can cause cardiovascular diseases in human beings when concentrations are high in food products from animal sources.
Buzzing by bees during flower pollination is significantly more powerful than that used for defence or flight, according to a new study from experts at the University of Stirling.
The research found that flower buzzing produced forces of more than 50G - five times that experienced by fighter jet pilots - and provides an important insight into the pollination process.
Dr David Pritchard, of the University's Faculty of Natural Sciences, led the study and believes the findings suggest that bees use specific types of buzzing vibrations for certain tasks.
A study on marine biodiversity has identified seventy-three species of sea slugs in the coasts of Barcelona, an anthropized environment due to the urban metropolis.
In this group of gastropod molluscs, the most abundant in the urban coasts are sea hares, according to the article coordinated by the tenure university lecturer Manuel Ballesteros, from the Faculty of Biology and the Biodiversity Research Institute (IRBio) of the University of Barcelona.
Meteorites give us insight into the early development of the solar system. Using the SAPHiR instrument at the Research Neutron Source Heinz Maier-Leibnitz (FRM II) at the Technical University of Munich (TUM), a scientific team has for the first time simulated the formation of a class of stony-iron meteorites, so-called pallasites, on a purely experimental basis.
Introducing the newly designed 'meta-grid' of nanoparticles into the epoxy casing of light-emitting diodes (LEDs) offers a substantial improvement of their light output, besides increasing lifetime, according to the scientists who invented it. A 'meta-grid' is a specially designed, optimized two-dimensional array of metallic nanoparticles, which needs to be placed at a specific location within the epoxy casing of the LEDs.
Women compose half of the entering classes of medical students, yet they are underrepresented in many of the largest surgical specialties. While some efforts are underway to recruit more women into surgical specialties, little information has been available on the rate at which the gender gap is closing.
The possibility of achieving room temperature superconductivity took a tiny step forward with a recent discovery by a team of Penn State physicists and materials scientists.
The surprising discovery involved layering a two-dimensional material called molybdenum sulfide with another material called molybdenum carbide. Molybdenum carbide is a known superconductor -- electrons can flow through the material without any resistance. Even the best of metals, such as silver or copper, lose energy through heat. This loss makes long-distance transmission of electricity more costly.
Air conditioning and other space cooling methods account for about 10% of all electricity consumption in the U.S., according to the U.S. Energy Information Administration. Now, researchers reporting in ACS Applied Materials & Interfaces have developed a material that cools the wearer without using any electricity. The fabric transfers heat, allows moisture to evaporate from the skin and repels water. Watch a video about the new fabric here.
In a pilot study of people living with HIV or high levels of cholesterol, Johns Hopkins Medicine researchers found that a six-week course of a cholesterol-lowering medication improved the function of the coronary arteries that provide oxygen to the heart.
The drug used in the study, a PCSK9 inhibitor, lowers the activity of PCSK9, a protein involved in cholesterol metabolism. These levels are higher in people with HIV and in those with high cholesterol.
Paleontologists have described in the Journal of Vertebrate Paleontology a large owl that killed medium-sized mammals with its feet and claws some 55 million years ago. "Today, owls kill with their beak," says paleontologist Thierry Smith (RBINS), who participated to the study of the well-preserved skeleton from Wyoming, USA. Primoptynx poliotaurus is a new species and a new genus.
When we get a wound on our skin, the cells in our bodies quickly mobilize to repair it. While it has been known how cells heal wounds and how scars form, a team led by researchers from Washington University in St. Louis has determined for the first time how the process begins, which may provide new insight into wound healing, fibrosis and cancer metastasis.
