How DNA Could Help Catch Elephant Poachers
Every year criminals around the world trade billions of dollars in products derived from wildlife. The elephant trade in particular has rankled government officials around the world with tens of thousands of the large mammals killed in Africa every year—a conservation threat, given the dwindling numbers of elephants in the wild. Now, scientists say that they may be able to use DNA from government seizes of illegal ivory tusks to trace elephants’ origins, a potentially groundbreaking method for law enforcement. Large-scale poaching, which accounts for more than 70% of the ivory trade, may be confined to just two areas, according to an analysis of the DNA tests published in the journal Science. “By being able to say that these came from just a couple of areas means that we can target those areas much more efficiently with law enforcement,” said study author Sam Wasser, on a conference call for journalists. Wasser, a research professor at the University of Washington, and his co-authors first analyzed samples of more than 1,300 elephants in 71 locations across the African continent. They then compared the DNA of living elephants to DNA found in seized ivory. More than 85% of ivory from forest elephants came from a protected reserve that includes land in Gabon, Cameroon and Republic of Congo, and more than 85% of ivory from savanna elephants came from two reserves in Tanzania and Mozambique. The network of major ivory traders is the world’s fourth ...

Authors: Kalkbrenner C, Brucher R, Kesztyüs T, Eichenlaub M, Rottbauer W, Scharnbeck D Abstract The current gold standard for assessment of most sleep disorders is the in-laboratory polysomnography (PSG). This approach produces high costs and inconveniences for the patients. An accessible and simple preliminary screening method to diagnose the most common sleep disorders and to decide whether a PSG is necessary or not is therefore desirable. A minimalistic type-4 monitoring system which utilized tracheal body sound and actigraphy to accurately diagnose the obstructive sleep apnea syndrome was previously develo...

CONCLUSION: Putting these figures in the appropriate international context requires the acquisition of comparable data in multiple countries and is the main task of international TBI consortia. PMID: 30995953 [PubMed - in process]
Authors: Gensichen J, Hiller TS, Breitbart J, Brettschneider C, Teismann T, Schumacher U, Lukaschek K, Schelle M, Schneider N, Sommer M, Wensing M, König HH, Margraf J Abstract BACKGROUND: We evaluated a team-based program of exercises for patients with panic disorder with or without agoraphobia (PDA) in primary care. METHODS: 419 patients with PDA (mean age 46.2 years, standard deviation 14.4 years; 74% female) were included in this cluster-randomized, controlled intervention trial. The patients were blinded with respect to their group assignment at baseline. Patients in the intervention group (36 primary...
