The challenges of North American specialty cut flowers Posted: 14 Jun 2019 01:32 PM PDT Cut flower production in the United States and Canada has increased in recent years. Due to this resurgence, more information is needed regarding current production and postharvest issues. |
Small cluster of neurons is off-on switch for mouse songs Posted: 14 Jun 2019 01:31 PM PDT Researchers have isolated a cluster of neurons in a mouse's brain that are crucial to making the squeaky, ultrasonic 'songs' a male mouse produces when courting a potential mate. |
What drives Yellowstone's massive elk migrations? Posted: 14 Jun 2019 11:12 AM PDT Yellowstone's migratory elk rely primarily on environmental cues, including a retreating snowline and the greening grasses of spring, to decide when to make the treks between their winter ranges and summer ranges, researchers show. Their study combined GPS tracking data from more than 400 animals in nine major Yellowstone elk populations with satellite imagery to create a comprehensive model of what drives these animals to move. |
A shady spot may protect species against rapid climate warming Posted: 14 Jun 2019 09:58 AM PDT A shady refuge on a hot day could be more than a simple comfort in a warming world. Finding a cooler spot might save several species that would otherwise go extinct due to global warming, according to a new analysis. |
Better prognosticating for dogs with mammary tumors Posted: 14 Jun 2019 09:58 AM PDT For dogs with mammary tumors, deciding a course of treatment can depend on a variety of factors, some of which may seem to contradict one another. With a new, practical system developed by veterinarians, determining a prognosis and making treatment decisions should be an easier task. |
No evidence for increased egg predation in the Arctic Posted: 14 Jun 2019 08:19 AM PDT Climate and ecosystems are changing, but predation on shorebird nests has changed little across the globe over the past 60 years, finds an international team of 60 researchers. The study published in Science on 14 June 2019 challenges a recent claim that shorebird eggs are more often eaten by predators due to climate change, and more so in the Arctic compared to the tropics. The research shows that these claims are a methodological artefact. |
Researchers find genes that could help create more resilient chickens Posted: 14 Jun 2019 08:19 AM PDT Scientists have identified genes that may help farmers, especially ones in low- and middle-income countries, breed chickens that can resist one of the biggest disease threats facing poultry today. |
Virus genes help determine if pea aphids get their wings Posted: 14 Jun 2019 08:19 AM PDT Researchers shed light on the important role that microbial genes, like those from viruses, can play in insect and animal evolution. |
Posted: 14 Jun 2019 05:29 AM PDT Researchers have filled two knowledge gaps: The vacuoles of plant cells can be excited and the TPC1 ion channel is involved in this process. The function of this channel, which is also found in humans, has been a mystery so far. |
Posted: 14 Jun 2019 05:29 AM PDT Despite how essential plants are for life on Earth, little is known about how parts of plant cells orchestrate growth and greening. By creating mutant plants, researchers have uncovered a cellular communication pathway sought by scientists for decades. |
