Despite being outlawed in 2012 in the US, the synthetic drugs known as 'bath salts' -- which really aren't meant for your daily bath -- are still readily available in some retail shops, on the Internet and on the streets. To help law enforcement, scientists are developing a novel method that could be the basis for the first portable, on-site testing device for identifying the drugs.
Nationally, hand hygiene adherence by healthcare workers remains staggeringly low despite its critical importance in infection control. A new study found that healthcare workers' adherence to hand hygiene is better when other workers are nearby.
A swamp-dwelling, plant-munching creature that lived 19 million years ago in Africa has been named after Rolling Stones lead singer Sir Mick Jagger, because of its big, sensitive lips and snout. The name of the animal, Jaggermeryx naida, translates to 'Jagger's water nymph.'
The mere whiff of a dreamy perfume can help conjure new feelings or stir a longing for the past. But the creation of these alluring scents, from the high-end to the commonplace, can also incur an environmental toll. That could change as scientists examine a more sustainable way to produce a key perfume ingredient and supply it to fragrance makers around the world.
For detecting cancer, manual breast exams seem low-tech compared to other methods such as MRI. But scientists are now developing an 'electronic skin' that 'feels' and images small lumps that fingers can miss. Knowing the size and shape of a lump could allow for earlier identification of breast cancer, which could save lives.
The experimental drug nintedanib, combined with standard chemotherapy with paclitaxel, causes a total remission of tumors in 50 percent of patients suffering from early HER-2-negative breast cancer, the most common type of breast cancer.
Imaging technologies are useful in evaluating response to cancer treatment, and this can be done quite effectively for most tumors using RECIST, Response Evaluation Criteria in Solid Tumors. RECIST works well for tumors located in soft tissue, but not cancers that spread to the bone. More effort, therefore, is needed to improve our understanding of how to monitor the response of bone metastases to treatment using MRI and PET imaging.
Researchers studying a rare, blistering disease have discovered new details of how autoantibodies destroy healthy cells in skin. The research has the potential to help clinicians identify who may be at risk for developing Pemphigus vulgaris (PV), an autoimmune skin disorder, by distinguishing pathogenic (disease-causing) autoimmune antibodies from other nonpathogenic autoimmune antibodies.
According to the traditional theory of nerves, two nerve impulses sent from opposite ends of a nerve annihilate when they collide. New research now shows that two colliding nerve impulses simply pass through each other and continue unaffected. This supports the theory that nerves function as sound pulses.
Computer scientists have successfully funded on Kickstarter a new and improved version of CodeSpells, a first-person player game they developed that teaches players how to code.
The genetic code of the liver fluke parasite, Opisthorchis viverrini, has been cracked by an international team of researchers using a unique DNA analysis technique. Opisthorchis viverrini is a trematode that infects millions in Asia, and is a significant risk factor for Cholangiocarcinoma (CCA) or bile duct cancer.
New research from biological anthropologists has shown that the use of the non-dominant hand was likely to have played a vital role in the evolution of modern human hand morphology: the production of stone tools requires the thumb on the non-dominant hand to be significantly stronger and more robust than the fingers.
Researchers have 'filmed' the movement of lipid molecules using an X-ray stroboscope. Their study offers new insights into the dynamics of biomolecules, which compose materials such as cell membranes.
Attending work while suffering a depressive illness could help employees better manage their depression more than taking a sickness absence from work, a new study has found. The study is the first to estimate the long-term costs and health outcomes of depression-related absence as compared to individuals who continue to work among employees with depression.
Researchers have shown for the first time how the activation of a receptor provokes the inflammation and bone degradation of rheumatoid arthritis -- and that activation of this one receptor, found on cells in the fluid of arthritic joints, is all that is required.
Compared to the age of the solar system -- about four-and-a-half billion years -- a couple of decades are next to nothing. Some planetary locales change little over many millions of years, so for scientists who study the planets, any object that evolves on such a short interval makes for a tempting target for study. And so it is with the ever-changing rings of Saturn.
A simple question about appetite can provide insights into old people's general health that may help reduce their risk of dying. A team has now investigated the connection between appetite and mortality in great depth.
The work took nearly four years to complete and it opens a fundamentally new direction in photonics -- with far-reaching potential consequences for the control of photons in optical fiber channels.
A new study on the frequency of past giant earthquakes in the Indian Ocean region shows that Sri Lanka, and much of the Indian Ocean, is affected by large tsunamis at highly variable intervals, from a few hundred to more than 1,000 years. The findings suggest that the accumulation of stress in the region could generate as large, or even larger tsunamis than the one that resulted from the 2004 magnitude-9.2 Sumatra earthquake.
Numerous studies have linked social interaction to improved health and survival in humans, and new research confirms that the same is true for baboons. A long-term study of more than 200 wild female baboons finds that the most sociable females live two to three years longer than their socially isolated counterparts. Socializing with males gave females an even bigger longevity boost than socializing with other females, the researchers found.
