JB on the Rocks: Home Brew

A very dear friend of mine, who was also the Best Man in my wedding, got me hooked on home brewing when he sent me a small commercial home brew kit for Christmas a couple years ago.

I guess it's only fair, really, since I am the man responsible for turning him into a craft beer snob when we were roommates in Phoenix almost a half-decade ago. ?He'd been a "Bud Light" kind of beer drinker until then, and while I don't begrudge people for eating or drinking as they prefer (I drink red wine with seafood, after all!) I also felt it my duty to introduce him to real, craft, varied, different beer. ?Beers that are made with the knowledge of the grains, different types of hops, a keen attention to detail, the understanding of the biochemistry behind extracting fermentable sugars from malted barley... these are the tools in the chest of a master brewer. ?

As an experienced shooter will re-zero his rifle for a different type of ammunition, or how she will be able to tell you the difference between a factory trigger and a custom trigger by a gunsmith, so too can a master brewer tell you why a particular strain of hops will work better with this grain but not that. ?These tools of the craft, and the loving attention and effort put into a true craft beer, set them apart from the bland, tasteless, mass-produced crap that the massive breweries spit out (*cough*Bud sucks*cough*)

What is a craft beer, you might ask. ?Simple enough in concept, harder to define in practice. ?My metric is simple: If I can find it in every single state, or at a convenience store, it is NOT a craft beer. ?These are the beers you go out of your way to find... it's a liquor store where you know the owner and he stocks a six pack of Mad Anthony's Harry Baal's Irish Stout in the back, just for you. ?It's the beer that you take to a Blogshoot Meet a couple states away, because you know they can't get it there. ?It's the beer that you mention on FaceCrack and EVERY single friend you have says "Never heard of it."

So I introduced Brian to craft beer, and he was hooked. ?Being an adventurous sort, and also a frugal man, he started brewing his own beers. ?Once some basic equipment is purchased, you can brew beer for less than you can buy it, and that's never more true than in jurisdictions that place large taxes on "vices" like beer.?

I'd suggest that beer isn't a vice, it's a food group, but I digress. ?

At any rate, you can brew about 54 bottles (that's two cases plus a six-pack for those without a calculator) for around $40 or so... or about $0.75 per beer. ?

And then Brian sent me a brewing kit. ?I made it on December 31st, 2011, which is the same day I proposed to my wife, and thus was born "Proposal Porter." ?Still have a couple bottles, can't bring myself to drink them. ?Maybe on our anniversary. ?

So I've been brewing my own beer for a while now. ?It's fun, it is a nice way to kill a few hours when the freezing rain falls and the dogs would rather nap by the fireplace than go for a walk, and it's an opportunity to brew what I like. ?

This past February 2nd, Groundhog Day, Missus JB and I brewed up a Pale Ale. ?There's an unwritten rule to home brewing: One must drink home brew when making home brew. ?So, as the wort chilled before getting yeast added, we were quite tipsy and trying to think up a name. ?In a flash of brilliance, the Missus came up with "Kill Phil Pale Ale."

And the rest is carbonated, hoppy, clean finishing history:

Sl?inte.

No sign of Florida man swallowed by sinkhole while asleep

SEFFNER, Florida (Reuters) - Florida rescue personnel on Saturday searched for a Florida man who disappeared into a sinkhole that swallowed his whole bedroom while he was asleep in his suburban Tampa home.

Jeff Bush, 36, who is presumed dead, was in bed when the other five members of the household who were getting ready for bed on Thursday night heard a loud crash and Jeff screaming.

Jeff's brother, 35-year-old Jeremy Bush, jumped into the hole and furiously kept digging to find his brother.

"I really don't think they are going to be able to find him," Jeremy said on Saturday. He "will be there forever."

A small memorial of balloons and flowers for his brother had formed near the house on Saturday morning.

"I thank the Lord for not taking my daughter and the rest of my family," he said.

Jeremy himself had to be rescued from the sinkhole by the first responder to the emergency call, Douglas Duvall of the Hillsborough County Sheriff's Office. When Duvall entered Jeff Bush's bedroom, all he saw was a widening chasm but no sign of Jeff.

"The hole took the entire bedroom," said Duvall. "You could see the bed frame, the dresser, everything was sinking," he said.

Norman Wicker, 48, the father of Jeremy's fianc?e who also lived in the house, ran to get a flashlight and shovel.

"It sounded like a car ran into the back of the house," Wicker said.

Authorities have not detected any signs of life after lowering listening devices and cameras into the hole.

"There is a very large, very fluid mass underneath this house rendering the entire house and the entire lot dangerous and unsafe," Bill Bracken, the head of an engineering company assisting fire and rescue officials, told the news conference late on Friday.

"We are still trying to determine the extent and nature of what's down there so we can best determine how to approach it and how to extricate," Bracken said.

After suspending the search overnight, it resumed at daylight on Saturday, with engineering consultants trying to determine the extent of the collapse so that a perimeter boundary can be established for setting up heavy equipment for future excavation.

Several nearby homes were evacuated in case the 30-foot (9-meter) wide sinkhole got larger but officials said Friday it only appeared to be getting deeper.

Soil samples showed that the sinkhole has compromised the ground underneath a home next door, engineers said Saturday.

The residents of that house were allowed 20 minutes in their home on Saturday to gather belongings. Firefighters and residents formed an assembly line to move items out of the house into SUVs and trucks.

Rescue officials said that in addition to soil samples, they were focusing on engineering analysis, ground penetration radar and other techniques to determine the extent of the ongoing collapse. Listening devices were being used to detect any evidence of life although Bush was presumed dead.

The Bush brothers worked together as landscapers, according to Leland Wicker, 48, one of the other residents of the house.

The risk of sinkholes is common in Florida due to the state's porous geological bedrock, according to the Florida Department of Environmental Protection. As rainwater filters down into the ground, it dissolves the rock, causing erosion that can lead to underground caverns, which cause sinkholes when they collapse.

Louse genetics offer clues on human migrations

Thursday, February 28, 2013

A new genetic analysis of human lice from across the world sheds light on the global spread of these parasites, their potential for disease transmission and insecticide resistance. The results are published February 27 in the open access journal PLOS ONE by Marina S. Ascunce and colleagues from the Florida Museum of Natural History, University of Florida.

Lice have been constant travel companions for humans ever since they left Africa and began colonizing other parts of the world. Since they have evolved along with humans, the geographic distribution of lice can reveal patterns of human migrations.

In the present research, the authors used available genomic data from human lice to identify genetic markers that can be used to determine which louse populations bred with one another. Their results improve our understanding of how lice have evolved resistance to insecticides, and can help improve methods of controlling these pests. These genetic markers can also be used to understand the differences between head and clothing lice, since the latter are capable of transmitting deadly bacterial diseases.

The authors suggest that these genetic markers may also reveal the tracks of human migrations across the globe, and can be used to test ideas about human evolution.

Silver nanoparticles may adversely affect environment

Thursday, February 28, 2013

In experiments mimicking a natural environment, Duke University researchers have demonstrated that the silver nanoparticles used in many consumer products can have an adverse effect on plants and microorganisms.

Fifty days after scientists applied a single low dose of silver nanoparticles, the experimental environments produced about a third less biomass in some plants and microbes.

These preliminary findings are important, the researchers said, because little is known about the environmental effects of silver nanoparticles, which are found in textiles, clothing, children's toys and pacifiers, disinfectants and toothpaste.

"No one really knows what the effects of these particles are in the environment," said Benjamin Colman, a post-doctoral fellow in Duke's biology department and a member of the Center for the Environmental Implications of Nanotechnology (CEINT).

"We're trying to come up with the data that can be used to help regulators determine the risks to the environment from silver nanoparticle exposures," Colman said. CEINT's research is funded by the National Science Foundation and the Environmental Protection Agency

Previous studies have involved high concentrations of the nanoparticles in a laboratory setting, which the researchers point out, doesn't represent "real-world" conditions.

"Results from laboratory studies are difficult to extrapolate to ecosystems, where exposures likely will be at low concentrations and there is a diversity of organisms," Colman said.

Silver nanoparticles are used in consumer products because they can kill bacteria, inhibiting unwanted odors. They work through a variety of mechanisms, including generating free radicals of oxygen which can cause DNA damage to microbial membranes without harming human cells.

The main route by which these particles enter the environment is as a by-product of sewage treatment plants. The nanoparticles are too small to be filtered out, so they and other materials end up in the resulting wastewater treatment "sludge," which is then spread on the land surface as a fertilizer.

For their studies, the researchers created mesocosms, which are small, man-made structures containing different plants and microorganisms meant to represent the environment. They applied sludge with low doses of silver nanoparticles in some of the mesocosms, then compared plants and microorganisms from treated and untreated mesocosms after 50 days.

The study appeared online Feb. 27 in the journal PLOS One.

The researchers found that one of the plants studied, a common annual grass known as Microstegium vimeneum, had 32 percent less biomass in the mesocosms treated with the nanoparticles. Microbes were also affected by the nanoparticles, Colman said. One enzyme associated with helping microbes deal with external stresses was 52 percent less active, while another enzyme that helps regulate processes within the cell was 27 percent less active. The overall biomass of the microbes was also 35 percent lower, he said.

"Our field studies show adverse responses of plants and microorganisms following a single low dose of silver nanoparticles applied by a sewage biosolid," Colman said. "An estimated 60 percent of the average 5.6 million tons of biosolids produced each year is applied to the land for various reasons, and this practice represents an important and understudied route of exposure of natural ecosystems to engineered nanoparticles."

"Our results show that silver nanoparticles in the biosolids, added at concentrations that would be expected, caused ecosystem-level impacts," Colman said. "Specifically, the nanoparticles led to an increase in nitrous oxide fluxes, changes in microbial community composition, biomass, and extracellular enzyme activity, as well as species-specific effects on the above-ground vegetation."

The researchers plan to continue to study longer-term effects of silver nanoparticles and to examine another ubiquitous nanoparticle ? titanium dioxide.

    Michigan governor to declare Detroit fiscal emergency: source

    LANSING, Michigan (Reuters) - Michigan Governor Rick Snyder will officially declare a financial emergency for Detroit on Friday, paving the way for a state takeover of the city, a state government source said on Thursday.

    At a forum in Detroit, the Republican governor will endorse the February 19 findings of a six-member review team that concluded the city's dire financial situation constituted an emergency, according to the source, who asked not to be identified.

    Sara Wurfel, Snyder's spokeswoman, said the governor will outline "his determination on whether or not there is an emergency."

    The official declaration of an emergency for Michigan's biggest city will trigger a 10-day deadline for Detroit officials to request a hearing with Snyder. It will likely result in the appointment of an emergency financial manager to manage its fiscal affairs.

    The review team said the city is plagued by "operational dysfunction," but made no official recommendation on the need to appoint an emergency financial manager, leaving that to the governor.

    Detroit, which has been struggling for years with a falling population, shrinking tax base and large payroll for city services, has been operating since April 2012 under an agreement that gave the state some oversight. But the slow pace of reforms led Snyder to launch a new review of the city last December.

    If the state decides to appoint an emergency financial manager, that person could decide the city's only course for survival would be a bankruptcy filing in what would become the largest municipal bankruptcy in the United States.

    The emergency manager would be officially chosen by a state board composed of the state treasurer, budget director, and licensing and regulatory affairs director - all of whom are Snyder appointees.

    Snyder has publicly discussed qualifications he would seek in the manager and has said he had a short list of candidates for the job.
