About 2.5 billion people worldwide don't have access to sanitary toilets. Latrines are an option for many of those people, but these facilities' overwhelming odors can deter users, who then defecate outdoors instead. To improve this situation, fragrance scientists paired experts' noses and analytical instruments to determine the odor profiles of latrines with the aim of countering the offensive stench.

The World Health Assembly endorsed a global action plan Monday, calling for all member states to have national plans in place by May 2017 to stop the growth of resistant germs.
A team of researchers has discovered a certain type of soil bacteria can use their social behavior of outer membrane exchange to repair damaged cells and improve the fitness of the bacteria population as a whole.
Researchers have shown that they can use a microfluidic cell-squeezing device to introduce specific antigens inside the immune system’s B cells, providing a new approach to developing and implementing antigen-presenting cell vaccines.
Contrary to public perception and horrific cases that make headlines, serious mental problems are declining among the nation's youth, and there has been a big rise in how many are getting help, a new study finds. The study is mostly good news: more children and teens are taking mental health medicines than ever before, but more also are getting therapy, not just pills.
New research shows that infections can impair your cognitive ability measured on an IQ scale. The study is the largest of its kind to date, and it shows a clear correlation between infection levels and impaired cognition.
Robert A. Good, an American doctor born May 21, 1922, was the first person to successfully transplant bone marrow between people who weren’t identical twins. He is considered to be the founder of immunology in its present form.
With the help of a computer program called "Rosetta," researchers have "redesigned" an antibody that has increased potency and can neutralize more strains of the AIDS-causing human immunodeficiency virus (HIV) than can any known natural antibody. The find suggests that computer-redesigned antibodies may speed the search for an effective therapy or vaccine for a virus that so far has eluded all attempts to eradicate it.
A class of FDA-approved cancer drugs may be able to prevent problems with brain cell development associated with disorders including Down syndrome and Fragile X syndrome, researchers have found. They showed that giving the leukemia drugs nilotinib or bafetinib to fly larvae with the equivalent of Fragile X prevented the wild overgrowth of neuron endings associated with the disorder.
Nanoengineers have developed a gel filled with toxin-absorbing nanosponges that could lead to an effective treatment for skin and wound infections caused by MRSA, an antibiotic-resistant bacteria. This "nanosponge-hydrogel" minimized the growth of skin lesions on mice infected with MRSA— without the use of antibiotics.
Moonshiners and home-brewers have long used yeast to convert sugar into alcohol. Those methods could also be adapted for something more significant: the production of drugs including opiates, antibiotics and anti-cancer therapeutics. According to new studies yeast can be engineered to convert sugar to alkaloids— plant-derived compounds such as codeine and morphine, naturally produced in the opium poppy.
A tiny microfluidic chip can capture circulating clusters of tumor cells, researchers said. The find could provide important new clues about how cancer spreads– and could even be a “breakthrough technology,” they said.
The number of stem cell clinics across the U.S. has surged from a handful in 2010 to more than 170 today. Many of the clinics are linked in large, for-profit chains. Doctors looking to get into the field need only take a weekend seminar offered by a training company.
Focusing on the difficult case of restoring cartilage, which requires both flexibility and mechanical strength, scientists investigated a new combination of 3-D printed microfiber scaffolding and hydrogels. The composites showed elasticity and stiffness comparable to knee-joint tissue, as well as the ability to support the growth and cross-linking of human cartilage cells.
The cross-ocean panic that accompanied the spread of Ebola in Western Africa was fueled by the unthinkable: the worst-case scenario that the dreaded virus could go airborne. No need to worry, according to researchers, who have analyzed decades of the virus’s known evolution.
A new target for drug development in the fight against the deadly disease malaria has been discovered. Researchers have described how they identified the drug target while studying the way in which the parasites Toxoplasma gondii, which causes toxoplasmosis, and Plasmodium, which causes malaria, access vital nutrients from their host cells.
A laboratory at Princeton University that experiments on marmosets was cited by federal authorities following an animal escape and fight in December. The single citation was for failing to secure a primary enclosure– but the Ivy League school’s animal research program has been accused of other improprieties in recent years.
The May issue of Laboratory Equipment has a cover story on the International Space Station, and how it has been able to stay state-of-the-art 15 years into its mission. Other articles detail different research approaches to HIV, collaboration in health care, calibration standards and rubber flooring. Special sections include life science and biomedical and lab design and furnishings.
The Obama Administration has chided insurance companies over their coverage of female contraception. The warning came at the beginning of National Women’s Health Week– and after several reports indicated that women’s access to contraception was being impeded by some insurers.
I read a study the other day that I find both hard to believe and disagreeable. The study centers on media coverage of public health measures, specifically vaccinations. It examines two politically charged health controversies. According to the study, media coverage of both events did not start by highlighting the political aspects of the controversies.
With certain critical treatments, personalized care includes the ability to monitor the concentration of medicines in the patient's body, in order to adjust the treatment. Now, researchers have come up with a quick and portable new device for measuring the amount of medicinal drugs in blood.
More than 25 million people rely on Adderall. But how does amphetamine, the active ingredient in Adderall, work?
The Univ. of Minnesota is apologizing to a man who claimed he was coerced into enrolling in a schizophrenia drug trial, a second local case to raise questions about patient safeguards during research. While a yearlong investigation concluded Robert Huber wasn’t coerced, it did find that the university failed to provide safety information.
Scientists have discovered an extraordinary protein-cutting enzyme that has also evolved to glue proteins together, a find that may be valuable in the production of therapeutic drugs. They found the unusual enzyme in an ordinary plant, the sunflower.
A new study suggests the measles shot comes with a bonus: by preventing that disease, the vaccine may also help your body fight off other illnesses for years. It's long been known that contracting measles weakens the immune system for weeks or months, putting people at increased risk for potentially fatal infections. Now, scientists have found that this vulnerable period goes on much longer than thought, up to three years.
The FDA will ask a group of outside medical experts next month to evaluate a much-debated experimental drug designed to boost sexual desire in women. The meeting is the latest twist in the ongoing saga of flibanserin, a proposed female libido pill that the FDA has already twice declined to approve.
