| Small and isolated habitat patches crucial to species survival Posted: 10 Dec 2018 02:18 PM PST Small, local patches of habitat could be playing a much bigger role in conserving biodiversity than you think, according to new research. |
| Ocean fertilization by unusual microbes extends to frigid waters of Arctic Ocean Posted: 10 Dec 2018 01:51 PM PST Microbes that provide natural fertilizer to the oceans by 'fixing' nitrogen from the atmosphere into a form useable by other organisms are active in the cold waters of the Bering and Chukchi Seas. |
| How will the winds of climate change affect migratory birds? Posted: 10 Dec 2018 12:18 PM PST Under future climate scenarios, changing winds may make it harder for North American birds to migrate southward in the autumn, but make it easier for them to come back north in the spring. Researchers came to this conclusion using data from 143 weather radar stations to estimate the altitude, density, and direction birds took during spring and autumn migrations over several years. |
| Humans may be reversing the climate clock, by 50 million years Posted: 10 Dec 2018 12:06 PM PST Our future on Earth may also be our past. Researchers show that humans are reversing a long-term cooling trend tracing back at least 50 million years. And it's taken just two centuries. |
| Smelling the forest not the trees: Why animals are better at sniffing complex smells Posted: 10 Dec 2018 11:49 AM PST Animals are much better at smelling a complex 'soup' of odorants rather than a single pure ingredient, a new study has revealed. |
| Key players in the marine nitrogen cycle can utilize cyanate and urea Posted: 10 Dec 2018 09:29 AM PST The ammonia oxidizing archaea, or Thaumarchaeota, are amongst the most abundant marine microorganisms. Yet, we are still discovering which factors allow them to thrive in the ocean: A new publication reveals that marine Thaumarchaeota have a broader metabolism than previously thought. |
| Providers show interest in prescribing therapeutic cannabinoids Posted: 10 Dec 2018 09:28 AM PST Researchers have found many dermatologists are interested in learning more about and recommending therapeutic cannabinoids to their patients. |
| Solar activity research provides insight into sun's past, future Posted: 10 Dec 2018 08:58 AM PST Scientists have developed a new technique for looking at historic solar data to distinguish trustworthy observations from those that should be used with care. This work is critical to understanding the sun's past and future as well as whether solar activity plays a role in climate change. |
| Females prefer city frogs' tunes Posted: 10 Dec 2018 08:58 AM PST Urban sophistication has real sex appeal -- at least if you're a Central American amphibian. Male frogs in cities are more attractive to females than their forest-frog counterparts, according to a new study. |
| Unexpected impact of hurricanes on Puerto Rico's watershed Posted: 10 Dec 2018 08:57 AM PST Researchers have found unprecedentedly high levels of nitrate, an essential plant nutrient, in streams and watersheds of Puerto Rico for a year after two consecutive major hurricanes in 2017. This high amount of nitrate may have important climate change implications that could harm forest recovery and threaten ecosystems along Puerto Rico's coastline by escalating algal blooms and dead zones. |
| A glimmer of hope for the world's coral reefs Posted: 10 Dec 2018 08:56 AM PST The future of the world's coral reefs is uncertain, as the impact of global heating continues to escalate. However, according to a new study, the response of the Great Barrier Reef to extreme temperatures in 2017 was markedly different to one year earlier, following two back-to-back bouts of coral bleaching. |
| Scientists brew lava and blow it up to better understand volcanoes Posted: 10 Dec 2018 07:54 AM PST What happens when lava and water meet? Explosive experiments with humanmade lava are helping to answer this important question. This long-term, ongoing study aims to shed light on the basic physics of lava-water interactions, which are common in nature but poorly understood. |
| New light on blocking Shiga and ricin toxins -- And on an iconic biological process Posted: 10 Dec 2018 07:54 AM PST Researchers, setting their sights on Shiga toxin (player in the current E. coli outbreak from romaine lettuce) and ricin (a bioterrorism agent), have now identified potential protective strategies. Their study also sheds new light on glycosylation, the attachment of sugars to large molecules, key to cells' ability to create more diverse molecules beyond what's encoded in the genome. |
| New look at Puerto Rico post-Hurricane Maria Posted: 10 Dec 2018 07:53 AM PST Two new research efforts delve into Hurricane Maria's far-reaching effects on the island's forests and on its residents' energy and electricity access. |
| Scientists discover how birds and dinosaurs evolved to dazzle with colourful displays Posted: 10 Dec 2018 07:19 AM PST Iridescence is responsible for some of the most striking visual displays in the animal kingdom. Now, thanks to a new study of feathers from almost 100 modern bird species, scientists have gained new insights into how this color diversity evolved. |
| Plants as antifungal factories Posted: 10 Dec 2018 07:19 AM PST Researchers have developed a biotechnological tool to produce, in a very efficient manner, antifungal proteins in the leaves of the plant Nicotiana benthamiana. These proteins are promising biomolecules that could be used to develop new antifungals whose properties and mechanisms of action represent improvements on the existing ones, and which can be applied in diverse fields, including crop and postharvest protection and animal and human health. |
| Ozone depletion increases Antarctic snowfall, partially mitigates ice sheet loss Posted: 10 Dec 2018 07:19 AM PST Ozone layer depletion has increased snowfall over Antarctica in recent decades, partially mitigating the ongoing loss of the continent's ice sheet mass, new research finds. |
| The fauna in the Antarctica is threatened by pathogens humans spread in polar latitudes Posted: 10 Dec 2018 07:19 AM PST The fauna in the Antarctica could be in danger due the pathogens humans spread in places and research stations in the southern ocean. |
| Proteins for making tough rubber Posted: 10 Dec 2018 07:19 AM PST Inspired by nature, scientists have produced a synthetic analogue to vulcanized natural rubber. Their material is just as tough and durable as the original. They reveal the secret to their success: short protein chains attached to the side-chains of the polymer backbone ensure stable physical cross-linkage and give the material a ''self-reinforcing'' effect under strain. In contrast to conventional rubbers, it is much easier to recycle. |
| New method to treat life-threatening heart arrhythmias in dogs Posted: 10 Dec 2018 07:19 AM PST Researchers have developed a new treatment for dogs with a rare, but life-threatening, arrhythmia caused by atrioventricular accessory pathways (APs). The minimally invasive technique, which uses radiofrequencies, is modified from a human cardiology procedure and has a more than 95 percent success rate in treating dogs with this type of arrhythmia. |
| Life in Deep Earth totals 15 to 23 billion tons of carbon -- hundreds of times more than humans Posted: 10 Dec 2018 07:19 AM PST Barely living 'zombie' bacteria and other forms of life constitute an immense amount of carbon deep within Earth's subsurface -- 245 to 385 times greater than the carbon mass of all humans on the surface, according to Deep Carbon Observatory scientists nearing the end of a 10-year international collaboration to reveal Earth's innermost secrets. |
| Tiny Australian wallaby the last living link to extinct giant kangaroos Posted: 10 Dec 2018 06:28 AM PST Scientists reveal that Australia's pint-sized banded hare-wallaby is the closest living relative of the giant short-faced kangaroos which roamed the continent for millions of years, but died out about 40,000 years ago. |
| Invasive species and habitat loss our biggest biodiversity threats Posted: 10 Dec 2018 05:59 AM PST Invasive species and habitat loss are the biggest threats to Australian biodiversity, according to new research. Australia was rich in unique biodiversity, but has had a poor track record since European settlement. |
| Increasing seal population will not harm largest fish stocks in the Baltic Posted: 10 Dec 2018 04:25 AM PST Seals feeding on fish does not decrease fish stocks of Baltic cod, herring and sprat the most -- climate change, nutrient load and fisheries do, shows a new study. |
