Oxytocin, called the "love hormone" because it has been linked to social behaviors like cuddling, maternal care and pair bonding, is also necessary for female social interest during estrus.
A study Cell Press found oxytocin-responsive brain cells that are necessary for female social interest in male mice during estrus, the sexually receptive phase of their cycle. These neurons, found in the prefrontal cortex, may play a role in other oxytocin-related social behaviors such as intimacy, love, and mother-child bonding.
Next week, the Environmental Protection Agency is set to approve Enlist Duo–a new herbicide formulation that combines two popular herbicides, 2,4-Dichlorophenoxyacetic acid (2,4-D) and glyphosate (the active ingredient in Roundup), which are used to control weeds.

A new paper from the International Osteoporosis Foundation (IOF) says that one-third of all hip fractures worldwide occur in men, with mortality rates as high as 37% in the first year following fracture.
This makes men twice as likely as women to die after a hip fracture. Osteoporosis experts warn that as men often remain undiagnosed and untreated, millions are left vulnerable to early death and disability, irrespective of fracture type.
When a sturdy material becomes soft and spongy, it's been damaged in some way. But when it comes to complex fluids and biological cells, things may be different.
By looking at the microscopic building blocks – known as "filaments" – of biopolymer networks, researchers from Forschungszentrum Jülich, Germany and the FOM Institute AMOLF in the Netherlands, revealed (Nature Communications DOI: 10.1038/ncomms5060) that such materials soften by undergoing a transition from an entangled spaghetti of filaments to aligned layers of bow-shaped filaments that slide past each other.
A little known secret in data mining is that simply feeding raw data into a data analysis algorithm is unlikely to produce meaningful results.
From recognizing speech to identifying unusual stars, new discoveries often begin with comparison of data streams to find connections and spot outliers. But most data comparison algorithms today have one major weakness – somewhere, they rely on a human expert to specify what aspects of the data are relevant for comparison, and what aspects aren't. But experts aren't keeping pace with the growing amounts and complexities of big data.
Decaffeinated coffee drinking may benefit liver health, according to a paper in Hepatology by Researchers from the National Cancer Institute whichsayss that higher coffee consumption, regardless of caffeine content, was linked to lower levels of abnormal liver enzymes.
This suggests that chemical compounds in coffee other than caffeine may help protect the liver.
PHILADELPHIA — Higher levels of total cholesterol and triglycerides, two types of fat, in the blood of men who underwent surgery for prostate cancer, were associated with increased risk for disease recurrence, according to a study published in Cancer Epidemiology, Biomarkers & Prevention, a journal of the American Association for Cancer Research.

A new study of human placenta has provided evidence that flame retardant chemicals called polychlorinated biphenyls (PCBs), implicated as being endocrine disrupting chemicals, and find they can interfere with thyroid hormone action in pregnant women.
The implication is that PCBs can infiltrate the placenta during pregnancy and affect thyroid hormone activity at the cellular level. PCBs were used in transformers and other electrical equipment, paints, adhesives and tape. Although the endocrine-disrupting chemicals were banned in the United States in 1979, PCBs still are released into the environment from disposal sites or products manufactured prior to the ban. Most people have only been exposed to low levels of PCBs.
Tomatoes contain antioxidants such as vitamin C, lycopene, β-carotene, and phenolics. Antioxidants are substances capable of delaying or inhibiting oxidation processes caused by free radicals and are of interest to both consumers and plant biologists. Consumers, for their health-related contributions, and plant breeders for their ability to provide plants with natural resistance to biotic and abiotic stresses.
Look into the light - unless you want to keep your memories.
UC Davis psychologists have used light to erase specific memories in mice and proved a basic hypothesis fpr how different parts of the brain work together to retrieve episodic memories. Optogenetics, created by Karl Diesseroth at Stanford University, is an effort at manipulating and studying nerve cells using light. The techniques of optogenetics are becoming popular for brain function studies.
