VANCOUVER — Think Miley Cyrus, but with a few more legs.
Black widow spiders use jittery, abdominal movements not unlike twerking — the hip-shaking dance move made infamous by Cyrus — to navigate the dangerous world of arachnid mating, according to a newly published study from a team of British Columbia researchers.
Specifically, the vibrations from a “twerking” male black widow tell a female perched on her web that she’s being approached by a potential mate, rather than dinner.
Daniela Holmqvist of Sweden got a little more then she bargained during the front-nine of the ISPS Handa Australian Open in Yarralumla. Holmqvist was participating in the LPGA pre-qualifier and had made it to the fourth hole without incident, but things changed quickly as she tried to hit her second shot out of the rough.
Australia's deadly redback spider has established itself in New Zealand, posing a significant risk to humans as it threatens to colonise major cities, researchers have found.The venomous redback, a relative of the black widow, probably hitched a ride to New Zealand on imported goods from Australia and had established itself at sites on both the North and South Islands, scientists said.The government's AgResearch institute said in a study published this month that the redback had proved more resilient to New Zealand's cold, wet winters than initially expected.
The median age declined in seven states between 2012 and 2013, including five in the Great Plains, according to U.S. Census Bureau estimates released today. In contrast, the median age for the U.S. as a whole ticked up from 37.5 years to 37.6 years. These estimates examine population changes among groups by age, sex, race and Hispanic origin nationally, as well as all states and counties, between April 1, 2010, and July 1, 2013."We're seeing the demographic impact of two booms," Census Bureau Director John Thompson said. "The population in the Great Plains energy boom states is becoming younger and more male as workers move in seeking employment in the oil and gas industry, while the U.S. as a whole continues to age as the youngest of the baby boom generation enters their 50s."The largest decline in the nation was in North Dakota, with a decline of 0.6 years between 2012 and 2013. The median age in four other Great Plains states — Montana, Wyoming,South Dakota and Oklahoma — also dropped. Alaska and Hawaii also saw a decline in median age. (See Table 1.) In addition, the median age fell in 403 of the nation's 3,143 counties, many of which were in the Great Plains. Williams, N.D., the center of the Bakken shale energy boom, led the nation with a decline of 1.6 years. Next to Alaska, North Dakota had a heavier concentration of males (51.1 percent of the total population) than any other state.The nation as a whole grew older as the oldest baby boomers became seniors. The nation's 65-and-older population surged to 44.7 million in 2013, up 3.6 percent from 2012. By comparison, the population younger than 65 grew by only 0.3 percent.These statistics released today also include population estimates for Puerto Rico and its municipios by age and sex.Our nation is a study in contrasts when it comes to local age structure. There was a more than 42-year difference in the median ages of the county with the highest median age — Sumter, Fla., at 65.5 — and the county with the youngest median age — Madison, Idaho, at 23.1.
SYDNEY, N.S. — A Nova Scotia judge warned the public to be cautious of a 78-year-old woman known as the “Black Widow” as he sentenced her Tuesday to two years and nine months in prison for spiking her newlywed husband’s coffee with tranquilizers while on a honeymoon last fall.
Melissa Ann Shepard, who pleaded guilty Monday to administering a noxious substance and failing to provide the necessities of life to 76-year-old Fred Weeks, remains a public safety risk, Supreme Court Judge Joseph Kennedy said.
