Nearly four-fifths of 16- and 17-year-olds have encountered pornographic content on the Internet
Pornography is a multibillion-dollar business. Pornographic content is virtually ubiquitous on the Internet, and surveys suggest that 25% of all searches lead to explicit content. Given the size of the market, it's not surprising that young people are drawn to such sites, which are only a couple of clicks away.
Great reed warblers normally migrate by night during its month-long migration from northern Europe to Sub-Saharan Africa. However, researchers have now discovered that during the few occasions when it continues to fly during daytime, it flies at extremely high altitudes (up to 6300 meters). One possible explanation for this unexpected and consistent behaviour could be that the birds want to avoid overheating. The study is published in Science.
If you are reading this, chances are you have several other tabs open in your browser that you mean to get to eventually.
Internet browser tabs are a major source of friction on the internet. People love them. People hate them. For some users, tabs bring order and efficiency to their web browsing. For others, they spiral out of control, shrinking at the top of the screen as their numbers expand.
Losing an only child is more devastating than losing a spouse, according to study of Chinese parents
Which wound cuts deeper: the loss of an only child or loss of a spouse? A new study led by researchers at NYU Rory Meyers College of Nursing and Fudan University suggests that Chinese parents find the loss of an only child to be approximately 1.3 times as psychologically distressing than the loss of a spouse. The findings are published in the journal Aging & Mental Health.
A new University of Iowa study challenges the idea that gray matter (the neurons that form the cerebral cortex) is more important than white matter (the myelin covered axons that physically connect neuronal regions) when it comes to cognitive health and function. The findings may help neurologists better predict the long-term effects of strokes and other forms of traumatic brain injury.
Training the artificial intelligence models that underpin web search engines, power smart assistants and enable driverless cars, consumes megawatts of energy and generates worrying carbon dioxide emissions. But new ways of training these models are proven to be greener.
Scientists are calling for more stringent pesticide bans to lower deaths caused by deliberately ingesting toxic agricultural chemicals, which account for one fifth of global suicides.
A NHMRC funded study, in which the University of South Australia analysed the patient plasma pesticide concentrations, has identified discrepancies in World Health Organization (WHO) classifications of pesticide hazards that are based on animal doses rather than human data.
WASHINGTON -- Researchers have demonstrated a record-high laser pulse intensity of over 1023 W/cm2 using the petawatt laser at the Center for Relativistic Laser Science (CoReLS), Institute for Basic Science in the Republic of Korea. It took more than a decade to reach this laser intensity, which is ten times that reported by a team at the University of Michigan in 2004. These ultrahigh intensity light pulses will enable exploration of complex interactions between light and matter in ways not possible before.
Middle Triassic ichthyosaurs are rare, and mostly small in size. The new Besanosaurus specimens described in the peer-reviewed journal PeerJ – the Journal of Life and Environmental Sciences – by Italian, Swiss, Dutch and Polish paleontologists provide new information on the anatomy of this fish-like ancient reptile, revealing its diet and exceptionally large adult size: up to 8 meters, a real record among all marine predators of this geological epoch.
Among younger adults visiting the emergency department for chest pain, women may be getting the short end of the stick. Compared with men of similar age, women were triaged less urgently, waited longer to be seen, and were less likely to undergo basic tests or be hospitalized or admitted for observation to diagnose a heart attack, according to new research being presented at the American College of Cardiology's 70th Annual Scientific Session.
Social factors such as education, financial stability, food security and the neighborhood where someone resides were strongly correlated with whether or not individuals with heart disease adopted measures to prevent the spread of COVID-19, including wearing masks and working from home, according to a study presented at the American College of Cardiology's 70th Annual Scientific Session. The researchers say the findings draw attention to longstanding challenges related to social determinants of health.
LUGANO, 6 May, 2021- Researchers have discovered a novel biomarker to identify male COVID-19 patients most at risk for ICU admission. The findings presented today at EADV's 2021 Spring Symposium, suggest that men with genetic characteristics (phenotypes) sensitive to the male sex hormone androgen, are more likely to experience severe COVID-19 disease.
Proteins are the workhorses of cells, responsible for almost all biological functions that make life possible.
Understanding how specific proteins work is key to disease prevention and treatment, allowing us to lead longer, healthier lives.
Yet scientists still know nothing or very little about thousands of proteins that exist in our bodies and their role in keeping us alive.
In Alzheimer's disease, neurons in the brain die. Largely responsible for the death of neurons are certain protein deposits in the brains of affected individuals: So-called beta-amyloid proteins, which form clumps (plaques) between neurons, and tau proteins, which stick together the inside of neurons. The causes of these deposits are as yet unclear. In addition, a rapidly progressive atrophy, i.e. a shrinking of the brain volume, can be observed in affected persons. Alzheimer's symptoms such as memory loss, disorientation, agitation and challenging behavior are the consequences.
AURORA, Colo. (May 6, 2021) - Scientists examining the remains of 36 bubonic plague victims from a 16th century mass grave in Germany have found the first evidence that evolutionary adaptive processes, driven by the disease, may have conferred immunity on later generations of people from the region.
