When lemons give you life: Herpetofauna adaptation to citrus orchards in Belize

EurekAlert! - Dom, 10/15/2017 - 22:00
Reptile and amphibian communities exhibit a promising level of resilience to agricultural lands, confirms a study recently published in the open-access journal ZooKeys. In their study, herpetologist Russell Gray and his research team compared forested areas to manicured citrus orchards and reclaimed orchard forests in Stann Creek, Belize. Further intriguing discoveries were made when the Category 1 Hurricane Earl hit the study site.

New antibiotic resistance genes found

EurekAlert! - Dom, 10/15/2017 - 22:00
Researchers at Chalmers University of Technology and the University of Gothenburg, Sweden, have found several previously unknown genes that make bacteria resistant to last-resort antibiotics. The genes were found by searching large volumes of bacterial DNA and the results are published in the scientific journal Microbiome.

Waves in lakes make waves in the Earth

EurekAlert! - Dom, 10/15/2017 - 22:00
In a study published today in the Journal of Geophysical Research Solid Earth, scientists at the University of Utah report that small seismic signals in lakes can aid science. As a record of wave motion in a lake, they can reveal when a lake freezes over and when it thaws. And as a small, constant source of seismic energy in the surrounding earth, lake microseisms can shine a light on the geology surrounding a lake.

EurekAlert! - Dom, 10/15/2017 - 22:00
The opioid epidemic is the most important health issue in West Virginia, above obesity, cancer, chronic obstructive pulmonary disease (COPD) and dental disease, according to a state-based public opinion survey commissioned by Research!America. A strong majority of West Virginians (84%) say prescription pain medication abuse and addiction is a major problem in their community, and more than two-thirds (71%) say they know someone who experienced pain so severe they sought prescription medicines to treat it.

Study: New exercises help athletes manage dangerous breathing disorder

EurekAlert! - Dom, 10/15/2017 - 22:00
A novel set of breathing techniques developed at National Jewish Health help athletes overcome vocal cord dysfunction and improve performance during high-intensity exercise. Vocal cord dysfunction, now also referred to as exercise-induced laryngeal obstruction (EILO), has been shown to improve for athletes after being trained to use the new techniques. The findings were published in the Oct. 16, 2017, online issue of the Journal of Voice.

Fanged kangaroo research could shed light on extinction

EurekAlert! - Sáb, 10/14/2017 - 22:00
Fanged kangaroos -- an extinct family of small fanged Australian kangaroos -- might have survived at least five million years longer than previously thought.A University of Queensland-led study has found the species might have competed for resources with ancestors of modern kangaroos.

One in five witness someone collapse who requires CPR but the majority do not act

EurekAlert! - Sáb, 10/14/2017 - 22:00
An estimated one in five adults in the UK witness someone collapse who needs immediate CPR, yet the majority of people do not act, according to new research funded by the British Heart Foundation. Researchers at the University of Warwick carried out a survey of 2,000 people across the country to find out how likely people are to witness a life-threatening cardiac arrest.

Study calls for less shame and secrecy around menstruation in global conflict areas

EurekAlert! - Sáb, 10/14/2017 - 22:00
A new study found that girls and women in emergency contexts have inadequate access to safe and private facilities and supplies for menstrual hygiene management, and are provided with insufficient guidance by response teams on the basics of managing menstruation. Moreover, many staff have a limited understanding of what an improved response should entail, and instead, focus predominantly on supplies.
