A new rapid imaging protocol quickly and cheaply diagnosed heart ailments in patients in Peru.

Researchers report a successful classification of triple breast cancer patients, which for the first time discriminates those who can be cured from those who might suffer a relapse. It also identifies new pharmacological targets, and indicates that in patients with these targets, combined treatments with existing drugs could be effective.

Asian pitchers transplanted to Massachusetts bogs can mimic the living communities of natives so well that the pitcher plant mosquito — a specialized insect that evolved to complete its life cycle exclusively in North American pitchers — lays eggs in the impostors, new research shows.

Researchers have discovered that a modified version of an important immune cell protein could be used to treat Alzheimer's disease. The study reveals that soluble versions of a protein called TLR5 can reduce the buildup of amyloid plaques in the brains of Alzheimer's disease model mice and prevent the toxic peptide that forms these plaques from killing neurons.

Knowing approximately how many individuals of a certain species are out there is important for bird conservation efforts, but raw data from bird surveys tends to underestimate bird abundance. Researchers have now tested a new statistical method to adjust for this and confirmed several mathematical tweaks that can produce better population estimates for species of conservation concern.

Aerial insectivores — birds that hunt for insect prey on the wing — are declining across North America as agricultural intensification leads to diminishing insect abundance and diversity in many areas. A new study looks at how tree swallows' diets are affected by agriculture and finds that while birds living in cropland can still find their preferred prey, they may be working harder to get it.

New evidence supports international guidelines recommending surgery before 18 months of age for boys with undescended testes to reduce the risk of both testicular cancer and infertility later in life.

In China, people breathe air thick with the lung-damaging pollutant ozone two to six times more often than people in the United States, Europe, Japan, or South Korea, according to a new assessment. By one metric — total number of days with daily maximum average ozone values (8-hour average) greater than 70 ppb — China had twice as many high ozone days as Japan and South Korea, three times more than the United States, and six times more than Europe.

Physicians and computer scientists have shown it is easy to modify medical test results remotely by attacking the connection between hospital laboratory devices and medical record systems.

Candidiasis is a painful infection that affects a large number of individuals, occasionally causing severe pain that is solely controlled by resolution of infection. Here, Dectin-1 inhibition was found to block pain during fungal infection. Researchers found that clodronate, a drug that is currently used for osteoporosis treatment, could suppress severe pain in fungal infection, and that the Dectin-1 pathway could be an important new target for treatment of pain.
