New discovery pushes origin of feathers back by 70 million years
Published: Mon, 17 Dec 2018 12:59:08 EST
Description: An international team of palaeontologists has discovered that the flying reptiles, pterosaurs, actually had four kinds of feathers, and these are shared with dinosaurs -- pushing back the origin of feathers by some 70 million years.  więcej...
Baboon sexes differ in how social status gets 'under the skin'
Published: Mon, 17 Dec 2018 12:58:55 EST
Description: A growing body of evidence shows that those at the bottom of the socioeconomic ladder are more likely to die prematurely than those at the top. The pattern isn't unique to humans: Across many animals, the lower an individual's social status, the worse their health. But new research in baboons suggests that the nature of the status-health relationship depends on whether an individual has to fight for status, or it's given to them.  więcej...
Birds can mistake some caterpillars for snakes; can robots help?
Published: Mon, 17 Dec 2018 12:00:38 EST
Description: Researchers witnessed a hummingbird defending its nest from what it interpreted to be a snake, but was actually a caterpillar of the moth Oxytenis modestia.   więcej...
Foxes in the city: Citizen science helps researchers to study urban wildlife
Published: Fri, 14 Dec 2018 09:38:19 EST
Description: A team of researchers led by wildlife ecologists analyzed over 1,100 fox sightings made by the public as part of the citizen science project StadtWildTiere. The joint team of researchers has now shown that foxes prefer specific city areas and environments. The study also revealed that reports of fox sightings correlated with the educational level of the population.  więcej...
Unpredictable food sources drive some bats to cooperatively search for food
Published: Thu, 13 Dec 2018 15:56:10 EST
Description: With the help of novel miniature sensors, biologists have found that bat species foraged socially if their food sources were in unpredictable locations, such as insect swarms or fish schools. In contrast, bats with food sources at fixed locations foraged on their own and did not communicate with one another while foraging or eating.  więcej...
Genetically modified pigs resist infection with the classical swine fever virus
Published: Thu, 13 Dec 2018 15:56:04 EST
Description: Researchers have developed genetically modified pigs that are protected from classical swine fever virus (CSFV), according to a new study.  więcej...
Novel mechanisms of dengue and Zika virus infections and link to microcephaly
Published: Thu, 13 Dec 2018 14:21:23 EST
Description: New insights into how dengue and Zika viruses cause disease reveal strategies the viruses use to successfully infect their host and a link to microcephaly.  więcej...
New drug seeks receptors in sarcoma cells, attacks tumors in animal trials
Published: Thu, 13 Dec 2018 14:15:32 EST
Description: A new compound that targets a receptor within sarcoma cancer cells shrank tumors and hampered their ability to spread in mice and pigs, a study reports. The researchers conducted a multi-year, cross-disciplinary study that went from screening potential drug candidates to identifying and synthesizing one compound, to packaging it into nanoparticles for delivery in cells, to testing it in cell cultures and finally in mice and pigs with sarcoma tumors.  więcej...
Fifty years of decline in Queensland's coastal sharks
Published: Thu, 13 Dec 2018 10:13:36 EST
Description: Queensland's coastal shark numbers are continuing a 50-year decline, in sharp contradiction of suggestions of 'exploding' shark populations, according to a new analysis. Researchers analyzed data from the program, which has used baited drumlines and nets since 1962 to minimize human-shark interactions, and now spans 1,760 km of the Queensland coastline.  więcej...
Potential range for new invasive tick covers much of Eastern US
Published: Thu, 13 Dec 2018 10:13:15 EST
Description: Since the arrival of the Asian longhorned tick (Haemaphysalis longicornis) in North America was first reported in New Jersey in early 2018, it has been found in eight other states in the US and, by the looks of a new study comparing North American habitat with the invasive tick's native territory, it shouldn't be a surprise if it shows up in many more.  więcej...
