People concerned about human-insecticide exposure have stimulated interest in alternative bed bug control materials, including oil-based pesticides and detergent insecticides.

But how well do they work? Researchers from Rutgers University evaluated the efficacy of nine essential oil-based products and two detergents that are labeled and marketed as 'natural' bed bug control. 

The non-synthetic bed bug pesticides contain ingredients such as geraniol, rosemary oil, mint oil, cinnamon oil, peppermint oil, eugenol, clove oil, lemongrass oil, sodium lauryl sulfate, 2-Phenethyl propionate, potassium sorbate, and sodium chloride, included the following products:

Researchers have uncovered a molecular process in the brain known to control eating that transforms white fat into brown fat, and that impacts how much energy we burn and how much weight we can lose.  

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. 

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.
