Thermal paper cash register receipts account for high bisphenol A (BPA) levels  in humans

Thermal paper cash register receipts account for high bisphenol A (BPA) levels in humans

Bisphenol A (BPA) is a chemical that is used in a variety of consumer products, such as water bottles, dental composites and resins used to line metal food and beverage containers, and also is used in thermal paper cash register receipts. Now, research conducted at the University of Missouri is providing the first data that BPA from thermal paper used in cash register receipts accounts for high levels of BPA in humans. Subjects studied showed a rapid increase of BPA in their blood after using a skin care product and then touching a store receipt with BPA Continue reading

Genome editing technique advanced by researchers

Genome editing technique advanced by researchers

Customized genome editing — the ability to edit desired DNA sequences to add, delete, activate or suppress specific genes — has major potential for application in medicine, biotechnology, food and agriculture. Now, in a paper published in Molecular Cell , North Carolina State University researchers and colleagues examine six key molecular elements that help drive this genome editing system, which is known as CRISPR-Cas. NC State’s Dr. Continue reading

Large variation in Cesarean rates across US hospitals

Large variation in Cesarean rates across US hospitals

Cesarean delivery is the most common inpatient surgery in the United States. US cesarean rates increased from 20.7% in 1996 to 32.9% in 2009 but have since stabilized, with 1.3 million American women having had a cesarean delivery in 2011 Continue reading

Positive subliminal messages on aging improve physical functioning in elderly

Older individuals who are subliminally exposed to positive stereotypes about aging showed improved physical functioning that can last for several weeks, a new study led by the Yale School of Public Health has found. Continue reading

Mutation associated with cleft palate in humans, dogs identified

Mutation associated with cleft palate in humans, dogs identified

Scientists studying birth defects in humans and purebred dogs have identified an association between cleft lip and cleft palate — conditions that occur when the lip and mouth fail to form properly during pregnancy — and a mutation in the ADAMTS20 gene. Continue reading

Using feminist theory to understand male rape

Using feminist theory to understand male rape

Decades of feminist research have framed rape and sexual assault as a ‘women’s issue’, leaving little room for the experiences of male victims. Continue reading

Scientific breakthrough will help design antibiotics of the future

Scientific breakthrough will help design antibiotics of the future

Researchers at the University of Bristol focused on the role of enzymes in the bacteria, which split the structure of the antibiotic and stop it working, making the bacteria resistant. The new findings, published in Chemical Communications , show that it’s possible to test how enzymes react to certain antibiotics. It’s hoped this insight will help scientists to develop new antibiotics with a much lower risk of resistance, and to choose the best medicines for specific outbreaks. Continue reading

Blood Test Helps Predict Relapse in Patients with Autoimmune Disease Affecting the Kidneys

Blood Test Helps Predict Relapse in Patients with Autoimmune Disease Affecting the Kidneys

In patients with an autoimmune disease that often involves the kidneys, monitoring the blood for autoantibodies may help doctors predict the chance of relapse. The findings are from a study appearing in an upcoming issue of the Journal of the American Society of Nephrology ( JASN ). Such measures may help protect patients’ kidney health. Continue reading

Researchers look to exploit females’ natural resistance to infection

Researchers look to exploit females’ natural resistance to infection

Researchers have linked increased resistance to bacterial pneumonia in female mice to an enzyme activated by the female sex hormone estrogen. Females are naturally more resistant to respiratory infections than males. Now, an international team of scientists has shown that increased resistance to bacterial pneumonia in female mice is linked to the enzyme nitric oxide synthase 3 (NOS3) Continue reading
