3:33 PM | Weed adaptation
Oxford ragwortInvasive species undergo behavioural, phenological and morphological changes when confronted with novel conditions. However, we know remarkably little about the trajectories invasive species follow through time. This limits our understanding of the process of invasion, our power to predict the establishment and ecological effects of invasive species, and our understanding of how species respond to environmental changes. The main aim of this paper is to fill this knowledge gap, by […]

5:49 AM | Gynostemma
Gynostemma pentaphyllum, AKA Sweet vine tea One of the plants that Cassie Liveridge mentions in Homegrown Tea is one that I own, but which you very rarely see mentioned anywhere. I’ve had my Gynostemma pentaphyllum for four years, since buying it at the Eden Project. According to the label, it is hardy down to -10°C, but I think it has lived its entire life inside – mainly on the kitchen windowsill. It’s an odd plant. Some of the time it seems entirely happy on the […]

1:27 AM | Tired Hospital Workers Wash Hands Less Often
Hand-washing in hospitals is known to reduce patient infections, but a new study has found that hospital nurses and other employees wash their hands less frequently as the workday progresses.(Kimberly Smith)The research team, led by Hengchen Dai at the University of Pennsylvania, examined three years of hand-washing data from 4,157 caregivers in 35 U.S. hospitals. The team found that "hand-washing compliance rates" dropped by an average of 8.7 percent during a typical 12-hour work shift. The […]

11:49 PM | Birds Demonstrate the Value of Bonding After a Team Fight
As any fan of Hitchcock knows, birds often work together and, when threatened by rivals, are capable of marshalling their troops to defend resources. Now, researchers from the University of Bristol have found that clashes between rival bird groups have a long-lasting impact on the birds' behaviour. Biologists Dr. Andy Radford and Dr. Tim Fawcett have been studying the social behaviour of green woodhoopoes in Sub-Saharan Africa. Following a territorial conflict with their neighbors, victorious […]

9:42 PM | China’s Island Factory
China is in the midst of a land boom. Not of the real estate kind, but the ocean-dredging, reef-filling, artificial island kind. It’s all part of the country’s push to establish a claim to vast portions of the South China Sea, and the BBC has a fantastically-detailed multimedia piece on the island building efforts. ∞∞

7:33 PM | The city is an ecosystem, pipes and all
Courtney Humphries, reporting for the Boston Globe: As researchers delve into this world, they’re uncovering some surprises—like the unusual nitrogen cycles caused by homeowners raking up leaves in the fall, or the fast-growing urban trees. (BU ecologist Lucy Hutyra isn’t sure this is such a good thing: “Trees may be growing faster, but they could […]∞

Mugilogobius hitamA new species of Mugilogobius is described from Lake Towuti, central Sulawesi, diagnosed by its possession of a distinct transverse sensory papilla pattern on the cheek, overall blackish colour on head, body and fins and relatively large adult size for the genus. Although it may superficially resemble the black goby Mugilogobius amadi from Lake Poso, M. hitam, new species, lacks the numerous predorsal scales (22–36 in M. amadi versus 17–19), high second dorsal fin […]

It’s a little thing, this new breed of drought-tolerant alfalfa bred on New Mexico State University research plots in the southern part of my arid state. But it provides another clue (behind a Google surveywall) about what the path forward in western water management might look like: Adoption of a new crop takes time, so don’t ...Continue reading ‘Stuff I wrote elsewhere: Drought-tolerant alfalfa’ »

2:00 PM | Endangered in the Anthropocene: Human impacts threaten species of least concern
By many accounts, we are now living in the “Anthropocene,” an epoch defined entirely by the impacts humans have on the world. Those impacts are outsized and ever growing—and yet we’re not always aware of just how important our own influence really is. A new study shows that in one realm—endangered species conservation—paying attention to

5:54 AM | Arctic Blast Explodes Across the High Plains, Kicking Up a Large Dust Storm Visible From Space
As Arctic air rushed south across a large portion of the U.S. midsection yesterday, high winds at the leading edge of the cold front lofted palls of dust into the air over the high plains — so much so that they were visible to satellites orbiting high overhead. You can see the dust in the […]The post Arctic Blast Explodes Across the High Plains, Kicking Up a Large Dust Storm Visible From Space appeared first on ImaGeo.

3:05 AM | Mars Spacecraft Reveal Comet Flyby Effects on Martian Atmosphere
A comet traveling from the most distant region of our solar system passed amazingly close to Mars on October 19, and three spacecraft were there to observe the effects. If you had been standing on Mars, you would have seen thousands of shooting stars, according to astronomers from the University of Colorado, Boulder.Illustration of MAVEN spacecraft at Mars (NASA)The comet came from the Oort Cloud and passed within about 87,000 miles (139,500 kilometers) of Mars. That’s less than half the […]

Arboviruses are a group of viruses that are transmitted by arthropod vectors. The word arbovirus is actually an acronym (arthropod-borne virus) for a rather long list comprising four families of viruses one nastier than the other. The most prominent representatives are Dengue, West Nile, Yellow fever, and Tick-borne encephalitis.Among the arthropod vectors that are often involved in the transmission of arboviral and parasitic diseases worldwide are mosquitoes of the genus Culex . This genus is […]

1:22 PM | Opportunity costs, and tea
A lovely set-up for a spot of outdoor tea My problem with the garden at the moment is that I’m not seeing its possibilities – I’m seeing the opportunity cost of going down any particular route. The garden is (as they all are) of finite size. This shouldn’t be an issue, because I have finite resources of energy, time and money to lavish on it, so there will always be a limit to how many different things I can grow. But how to whittle down the list so that I don’t […]
