What is the common ground between making a cup of tea and putting on your shoes? Both actions consist of several movements in a row. "Just like language, which is composed of syllables arranged into sentences, many behaviors are comprised of several, sequential movements," explains Duncan Mearns.
Men are twice as likely as women to consider themselves to be good at lying and at getting away with it, new research has found.
People who excel at lying are good talkers and tell more lies than others, usually to family, friends, romantic partners and colleagues, according to the research led by Dr Brianna Verigin, at the University of Portsmouth.
Expert liars also prefer to lie face-to-face, rather than via text messages, and social media was the least likely place where they'd tell a lie.
Predator-prey cycles are among the fundamental phenomena of ecological systems: the population sizes of predators and their prey, for instance foxes and hares, are frequently subject to regular oscillations. In a long-term experiment, an international team of researchers led by Prof. Dr. Bernd Blasius from the University of Oldenburg, Germany, observed these oscillations in rotifer and unicellular algae populations across 50 cycles - a record period of time for this kind of study.
Extremely acute vision and the ability to rapidly process different visual impressions - these two factors are crucial when a peregrine falcon bears down on its prey at a speed that easily matches that of a Formula 1 racing car: over 350 kilometres per hour.
The visual acuity of birds of prey has been studied extensively and shows the vision of some large eagles and vultures is twice as acute as that of humans. On the other hand, up to now researchers have never studied the speed of vision among birds of prey, i.e. how fast they sense visual impressions.
The scientists research a building block of organic molecules needed for medical chemistry development. Spirocycles in nature is an element, that chemists are crazy about. This element presents in artemisinin, the most effective group of drugs against malaria.
An international research team in which Spanish experts participate has shown that sparse species are associated spatially in 90 % of the animal and plant communities studied.
"Animal and plant communities are organised in a similar way to cities, ghettos or ethnic neighbourhoods," the researchers say. "This organisation could be behind the persistence of rare species since they could avoid the competitive pressure of the most abundant species, either because they cooperate with each other or because they prefer specific microhabitats or both at the same time," they point out.
A study published in Environmental Toxicology and Chemistry underscores that the release of pollutants in one region can have implications beyond its borders; emphasizing the dire need for global collaboration on environmental issues. The study suggests that coal-burning activities in the Asia-Pacific region have influenced environmental conditions in the United States Pacific Northwest.
The research team of the IKBFU developed a fundamentally new method of manufacturing laser optics, which is based on the use of rare-earth metal ions of ytterbium and its oxide. The results of the work of scientists were recently published in the scientific journal Optics Communications.
Senior Researcher of the "Fabrika" Science and Technology Park, Ph.D. in Physics Anna Tsibulnikova told us:
A simple photograph taken with a mobile phone is able to detect irregularities in the labelling of rice, according to an investigation conducted by the Complutense University of Madrid (UCM) and the Scintillon Institute of San Diego (USA).
This has led scientists to develop an algorithm based on deep learning - a field of artificial intelligence - that is able to determine whether that rice is really the one described with the images taken with the smartphone.
New research from experts at the University of Nottingham could lead to an improved vaccine to protect against the bacterium, Neisseria meningitides that causes sepsis and meningitis.
The findings, published today in the journal 'Frontiers in Microbiology', could have major implications for the current meningococcal group B vaccines, Trumenba and Bexsero, both of which contain Factor H binding protein (FHbp), a lipoprotein found on the bacterium's surface.
Fatty liver, or hepatic steatosis, which develops when the body produces too much fat or doesn't metabolize fat efficiently enough, affects around 25% of the global population. Excess fat is stored in liver cells, where it accumulates and can cause fatty liver and other diseases.
Hamilton, ON (Dec. 20, 2019) - A major study has found that Canadian First Nations communities with greater socio-economic advantages, educational opportunities, social support of family members and greater trust between community members, have lower cardiac risk factors.
On the other hand, First Nations communities with difficulty accessing routine health care or affordable prescription medicines have a greater burden of cardiac risk factors.
The Earth's inner core is hot, under immense pressure and snow-capped, according to new research that could help scientists better understand forces that affect the entire planet.
The snow is made of tiny particles of iron - much heavier than any snowflake on Earth's surface - that fall from the molten outer core and pile on top of the inner core, creating piles up to 200 miles thick that cover the inner core.
The image may sound like an alien winter wonderland. But the scientists who led the research said it is akin to how rocks form inside volcanoes.
CHAMPAIGN, Ill. -- A new study in rats suggests that caffeine may offset some of the negative effects of an obesogenic diet by reducing the storage of lipids in fat cells and limiting weight gain and the production of triglycerides.
Rats that consumed the caffeine extracted from mate tea gained 16% less weight and accumulated 22% less body fat than rats that consumed decaffeinated mate tea, scientists at the University of Illinois found in a new study.
The effects were similar with synthetic caffeine and that extracted from coffee.
PHILADELPHIA -- (Dec. 19, 2019) -- A study from The Wistar Institute demonstrated that NAMPT, an enzyme critical for NAD+ biosynthesis, mediates selection of stem-like chemoresistant cells following cisplatin treatment. Researchers showed that a combination of cisplatin treatment with pharmacological inhibition of NAMPT suppresses the outgrowth of resistant cancer cells in vitro and prolongs survival in a preclinical model. These findings were published online in Cancer Research.
