Bystanders will intervene in nine-out-of-ten public fights to help victims of aggression and violence say researchers, in the largest ever study of real-life conflicts captured by CCTV.
The findings overturn the impression of the "walk on by society" where victims are ignored by bystanders.
Instead, the international research team of social scientists found that at least one bystander - but typically several - did something to help. And with increasing numbers of bystanders there is a greater likelihood that at least someone will intervene to help.
Over 1,700 children die from child abuse each year in the U.S., and far more sustain injuries that result in hospitalization. These deaths and severe injuries are preventable, but effective strategies require a deeper understanding of the caregivers causing the harm and the circumstances surrounding the child's injuries.
NEW YORK, NY (June 26, 2019)--Sitting for long periods of time has been linked to increased risk of cardiovascular disease and early death, but a new study suggests that not all types of sitting are equally unhealthy.
Vienna, 26 June 2019: Intracytoplasmic sperm injection (ICSI), the world's favoured means of fertilisation in assisted reproduction, offers no benefit over conventional in vitro fertilisation in fertility treatments without a male factor indication, according to results of a large multicentre study.
Imagine if your printer had an “unprint” button that used pulses of light to remove toner, curbing environmental impacts compared with conventional paper recycling.
Examining fossilised pigments, scientists from the University of Bristol have uncovered new insights into blue colour tones in prehistoric birds.
For some time, paleontologists have known that melanin pigment can preserve in fossils and have been able to reconstruct fossil colour patterns.
Melanin pigment gives black, reddish brown and grey colours to birds and is involved in creating bright iridescent sheens in bird feathers.
When you think of national parks, you might picture the vast plateaus of the Grand Canyon, the intricate wetlands of the Everglades, or the inspiring viewscapes of the Grand Tetons. You probably don't envision 100 million pounds of mashed water bottles, barbecue-smudged paper plates, and crumpled coffee cups - but that is the staggering quantity of garbage that is generated in our National Parks each year. And handling that amount of waste is becoming a huge problem.
Millions of acres of pine woodlands once covered a large portion of the Midwest. But as humans logged these trees and suppressed natural fires, the woodlands gave way to dense forests with thick leaf litter and tree species that were less fire-resistant, leading to more intense and unpredictable fires as well as the loss of native bird habitats.
By analyzing records in countries of the Amazon and Orinoco basins--which include Brazil, Venezuela, Colombia, Bolivia, Peru and Ecuador--a paper published today in Oryx--The International Journal of Conservation, categorized 85 past and present initiatives or projects that work to preserve the South American River Turtle, or charapa (Podocnemis expansa), a critically endangered species. These projects are protecting more than 147,000 female turtles across the basin, an unprecedented figure.
Cyanide and carbon monoxide are both deadly poisons to humans, but compounds containing iron, cyanide, and carbon monoxide discovered in carbon-rich meteorites by a team of scientists at Boise State University and NASA may have helped power life on early Earth. The extraterrestrial compounds found in meteorites resemble the active site of hydrogenases, which are enzymes that provide energy to bacteria and archaea by breaking down hydrogen gas (H2).
A prevailing theory in neuroscience holds that people make decisions based on integrated global calculations that occur within the frontal cortex of the brain.
However, Yale researchers have found that three distinct circuits connecting to different brain regions are involved in making good decisions, bad ones and determining which of those past choices to store in memory, they report June 25 in the journal Neuron.
Glioblastomas, the deadliest type of brain tumor in adults, attract "turncoats." These are macrophages, a type of immune cell, which promote tumor progression and mask tumors from the immune system's scrutiny. To better understand the cells that brain tumors recruit, scientists led by Dolores Hambardzumyan, PhD, developed advanced imaging techniques to visualize macrophages found in the brain tumors of living mice.
The results were published Monday, June 24 in PNAS.
WASHINGTON -- Inserting air into hot glass to form a bubble has been used to make glass objects since Roman times. In new work, researchers apply these same glass blowing principles on a microscopic scale to make specialized miniature cone-shaped lenses known as axicons.
Axicons are used to shape laser light in a way that is beneficial for optical drilling, imaging and creating optical traps for manipulating particles or cells. These lenses have been known for more than 60 years, but their fabrication, especially when small, is not easy.
They have been called the 'time bomb' of cardiology - ascending aortic aneurysms grow for decades without any warning signs and can be fatal once they rupture. They have taken the lives of well-known actors Alan Thicke and John Ritter and are a leading cause of death in North America.
In a new study published in EBioMedicine, researchers at Western University and Lawson Health Research Institute demonstrate what might be causing these aneurysms and potentially how to treat them.
ANAHEIM, CA (Embargoed until 9 a.m. PDT, Tuesday, June 25, 2019) - A novel therapy using two targeted treatments for prostate cancer has been shown to maximize efficacy while reducing side effects according to research presented at the Society of Nuclear Medicine and Molecular Imaging (SNMMI) 2019 Annual Meeting.
