Making people feel bad can be a strategy for helping them

EurekAlert! - Mar, 05/23/2017 - 22:00
People may try to make someone else feel negative emotions if they think experiencing those emotions will be beneficial in the long run, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The findings expand on previous research by revealing that people may sometimes seek to induce negative emotions in others for altruistic reasons, not simply for their own pleasure or benefit.

Dartmouth-led study finds heavier precipitation in the northeast began in 1996

EurekAlert! - Mar, 05/23/2017 - 22:00
Over the past century, the Northeast has experienced an increase in the number of storms with extreme precipitation. A Dartmouth-led study finds that the increase in extreme Northeast storms occurred as an abrupt shift in 1996, particularly in the spring and fall, rather than as a steady change over several decades. The findings were published in an early online release of the American Meteorological Society's 'Journal of Hydrometeorology.'

A fresh look inside the protein nano-machines

EurekAlert! - Mar, 05/23/2017 - 22:00
Proteins perform vital functions, they digest food and fight infections. They are in fact nano-machines, each one of them designed to perform a specific task. But how did they evolve to match those needs, how did the genes encode the structure and function of proteins? Researchers from the University of Geneva, Switzerland, the Institute for Basic Science, Korea, and the Rockefeller University, United States, have conducted a study that tackles this yet unanswered question.

New 'sperm radar' test may uncover secrets about male infertility

Scientists at the University of Sheffield have developed a new technique to examine human sperm without killing them -- helping to improve the diagnosis of fertility problems.

Song diversity hints at thrushes' evolutionary past

EurekAlert! - Mar, 05/23/2017 - 22:00
The Hermit Thrush is famous for its melodiously undulating song, but we know very little about whether -- and if so, how -- its songs vary across the large swath of North America that it calls home in the summer. A new study from The Auk: Ornithological Advances provides the first thorough overview of geographic variation in hermit thrush song structure and hints at how isolation and adaptation shape differences in song within a species.

Where body fat is carried can predict cancer risk

EurekAlert! - Lun, 05/22/2017 - 22:00
Scientists have found that carrying fat around your middle could be as good an indicator of cancer risk as body mass index (BMI), according to research published in the British Journal of Cancer today.

Chondroitin sulfate as good as widely used anti-inflammatory for knee osteoarthritis

EurekAlert! - Lun, 05/22/2017 - 22:00
High quality (pharmaceutical grade) chondroitin sulfate is as good as a widely prescribed non-steroidal anti-inflammatory drug (celecoxib) for the treatment of painful knee osteoarthritis, concludes research published online in the Annals of the Rheumatic Diseases.

Microhabitats enhance butterfly diversity in nature's imitation game

EurekAlert! - Lun, 05/22/2017 - 22:00
The spectacular range of colors and patterns that butterflies use to deter predators appears to result in part from very specific environmental conditions in so-called 'microhabitats,' researchers have found. This study helps to answer a paradoxical question in science; since species mimic each other's characteristics to ward off predators, theoretically they should all eventually develop the same pattern. Instead, there is a remarkable diversity of patterns which achieve this common goal.

Regular chocolate consumption may be linked to lower risk of heart flutter

Vitamin D supplementation combined with good sleeping habits may help manage pain-related diseases. This paper published in the Journal of Endocrinology, reviews published research on the relationship between vitamin D levels, sleep and pain management, and reports that levels of vitamin D combined with good quality sleep could help manage conditions including arthritis, menstrual cramps and chronic back pain.

Friends help female vampire bats cope with loss

EurekAlert! - Lun, 05/22/2017 - 22:00
When a female vampire bat loses a close relative, she may starve, because she depends on her mother and daughters to share blood by regurgitation. Vampires who have more non-kin social bonds (friends), do better when this happens.

Chan School of Public Health and in Denmark.
