A walk through most Midwestern state parks and nature preserves looks much different today than it did a century ago.
In contrast to a backdrop of diverse wildflowers, bees, butterflies and birds -- commonly seen in 19th-century landscape paintings -- modern wooded areas are now overrun by imported invasive plants, choking out most native species and disrupting much of the natural biodiversity.
Only a few years after its discovery, it is difficult to conceive of genetics without the CRISPR-Cas9 enzyme scissors, which allow for a very simple, versatile and reliable modification of DNA of various organisms. Since its discovery, scientists throughout the world have been working on ways of further improving or adjusting the CRISPR-Cas9 system to their specific needs.
AS the sole UK academic presenting a paper at a large-scale conference in the USA, the University of Huddersfield's Professor Jill Johnes introduced her audience to some new concepts in education finance. She also returned with a fresh idea of her own - to establish a new European association for education and finance policy.
Long-term infection with hepatitis B virus (HBV) can cause liver inflammation and increase the risk of liver cancer. Researchers from the US Centers for Disease Control and Prevention, however, found that resolving HBV infection was not associated with reduced rates of liver cancer.
Timing is everything when it comes to the development of the vertebrate face. In a new study published in PLoS Genetics, USC Stem Cell researcher Lindsey Barske from the laboratory of Gage Crump and her colleagues identify the roles of key molecular signals that control this critical timing.
A research group led by Osaka University and collaborative institutions discovered that disorders in the same gene PIGG are the cause for intellectual disability with seizures and hypotonia. PIGG is one of the enzymes active in the GPI anchor glycolipid synthesis and the current study revealed its significance in the development of the cerebral nervous system.
One of the secrets to rich milk production in lactation has been uncovered by researchers at the Walter and Eliza Hall Institute. Their studies have revealed that breast cells develop two nuclei as the breast switches on lactation to nurture the newborn.
This change begins to occur in late pregnancy with the generation of vast numbers of cells with two nuclei.
Melbourne researchers have uncovered the genes responsible for the way the body fights infection at the point of 'invasion' - whether it's the skin, liver, lungs or the gut.
Whiskey aficionados may claim that Manhattans must be made with fiery, grassy rye, while an Old Fashioned requires the sweetness of bourbon.
But a new study from a Drexel University food scientist shows the average consumer cannot discriminate between the two flavors.
Jacob Lahne, PhD, an assistant professor in the Center for Hospitality and Sport Management, found, in a blind sorting task of American ryes and bourbons, participants were more likely to group together products by brand rather than type of whiskey.
Lack of sleep has previously been found to impact the activation of the immune system, inflammation, carbohydrate metabolism and the hormones that regulate appetite. Now University of Helsinki researchers have found that sleep loss also influences cholesterol metabolism.
CHAMPAIGN, Ill. -- If shooting arrows from a crossbow into cubes of ballistics gelatin doesn't sound like biological science to you, you've got a lot to learn from University of Illinois animal biology professor Philip Anderson, who did just that to answer a fundamental question about how animals use their fangs, claws and tentacles to puncture other animals.
TORONTO, April 22, 2016--People who had cancer before receiving an organ transplant were more likely to die of any cause, die of cancer or develop a new cancer than organ recipients who did not previously have cancer, a new paper has found. However, the increased risk is less than that reported in some previous studies.
Previous research has shown that cancer survivors were at increased risk of cancer recurrence after a transplant. But the findings regarding the risk of death and developing a new cancer were inconsistent.
Babies with a high body mass index (BMI) at age two months are at risk for obesity at age two years, say pediatric researchers. The authors, in an online study published today in Pediatrics, say that BMI better predicts early childhood obesity than weight-for-length, the current standard measurement.
Managers who inspire their staff to perform above and beyond the call of duty may actually harm their employees' health over time, according to researchers from the University of East Anglia (UEA).
The findings suggest that constant pressure from these 'transformational leaders' may increase sickness absence levels among employees. They also indicate that some vulnerable employees in groups with transformational leaders may in the long term have increased sickness absence rates if they ignore their ill-health and frequently show up for work while ill, known as presenteeism.
RIVERSIDE, Calif. - Cocaine use has increased substantially among African Americans in some of the most underserved areas of the United States. Interventions designed to increase connection to and support from non-drug using family and friends, with access to employment, the faith community, and education, are the best ways to reduce substance use among African Americans and other minorities in low-income, resource-poor communities, concludes a study led by a medical anthropologist at the University of California, Riverside.
