A better way to count boreal birds

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.

How does agriculture affect vulnerable insect-eating birds?

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.

China is hot spot of ground-level ozone pollution

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.

Dectin-1-mediated pain is critical for the resolution of fungal inflammation

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.
