Moderate exercise seems to imï¿½prove memory function in people at risk for Alzheimerï¿½s disease, possibly helping to ward off symptoms of the memory-robbing illness, scientists have found.
ï¿½No study has shown that a drug can do what we showed is possible with exercise,ï¿½ said study leader J. Carï¿½son Smith of the University of Maryland. The researchers studied people with a condition considered a risk factor for Alzheimerï¿½s: mild cognitive impairment, or MCI, which signals an age-associated memory loss thatï¿½s greater than norï¿½mal.
"After 12 weeks of being on a moderate exercise program, study participants improved their neural efficiency ï¿½ basically they were using fewer neural [brain] resources to perform the same memory task,ï¿½ said Smith. The findings are published in the Jourï¿½nal of Alzheimerï¿½s Disease.
Two groups of physically inï¿½active older adults ranging from 60-88 years old were put on a 12-week exercise program that focused on regular treadmill walking, guided by a personal trainer. Both groups ï¿½ one with MCI and the other with healthy brain function ï¿½ improved their
cardiovascular fitness by about 10 percent, the study found. Both also improved memory performance and showed enhanced ï¿½neural efficiencyï¿½ during memory tasks.
The results were achieved with exercise consistent with the physical activity recommendations for older adults, the scientists said. These call for moderate intensity exercise (activity that increases your heart rate and makes you sweat, but isnï¿½t so strenuous that you canï¿½t hold a conversation while doing it) on most days for a weekly total of 150 minutes.
The exercise intervention was also found to improve word recall via a ï¿½list learning task.ï¿½ In this, people were read a list of 15 words and asked to remember and repeat as many words as possible on five consecutive attempts, and again after a distraction of being given another list of words.
ï¿½People with MCI are on a very sharp decline in their memory function, so being able to improve their recall is a very big step in the right direction,ï¿½ Smith said. The results suggest that exercise may reduce the need for over-activation of the brain to correctly remember something, he added.
Fishing beyond the Great Lakes
by Ray Rudolph
You donï¿½t need a boat to catch early fall crappies, just a good plan of action. It can be as relaxing or adventurous as you want it to be. Here are the three best areas to focus on to catch a stringer of crappies from the bank.
Way Up The Creek
ï¿½I grew up walking creeks,ï¿½ says crappie guide Barry Morrow. ï¿½Iï¿½m talking about the uppermost areas of creeks. Most have access within a short walking distance. Access will often be from a backroad or where a bridge crosses the creek. Some have parks or picnic areas that provide easy access. Public lands are best because you must have permission if you walk private land.ï¿½
He moves along in search of laydowns, old stumps or other cover where fish might hide. His weapon of choice is an 11-foot pole, 12-pound test Silver Thread line and a 1/4-ounce jighead with a Lindy Fat Watsit body. He agrees that most fishermen are more comfortable with a lighter-weight jighead, but that extra weight allows better sensitivity to feel the bottom, brush and bites.
ï¿½Start at the outside edges of brush or laydowns and work toward the inside,ï¿½ says Morrow. ï¿½The best bite is usually in the heart of the cover, but you can pick off aggressive fish from the edges without disturbing those deep in the thick stuff. Every piece of cover has a sweet spot and youï¿½ll soon learn a pattern where most of these are located.ï¿½
His technique requires both hands. Hold the pole in one hand and the line in the other. Pull the jig up to the tip, push the bait where you want it and then drop the jig by slowly moving your free hand toward the pole. Keep dropping it until you feel bottom or reach the strike zone. Controlling the line with your free hand is very important to this style of fishing. Because the rod is often confined within the branches of a laydown tree or bush, use that free hand to set the hook, pull the crappie almost to the tip then back it out.
Spillways for Crappie and More
Spillways damming man-made reservoirs are crappie guide Todd Huckabeeï¿½s favorite spots for summertime shore fishing. ï¿½Late summer is the perfect time,ï¿½ he said. ï¿½The lake becomes a little stagnate in late summer with the thermocline, low oxygen levels and water temperature all being stressful on the fish. But in the spillway the water will be cooler and dissolved oxygen levels are great. The fish feel better and are more active.ï¿½
He says with fairly uniform oxygen levels throughout the water column of a
spillway, crappie can be at any depth. Every spillway is different so there are no ï¿½cookie cutterï¿½ spots that work everywhere. However, he says two important features, current and eddies, are present at all spillways.
ï¿½Many fishermen use a cast and retrieve tactic, but their baits donï¿½t stay in the strike zone long enough. I use a float like the Wobble Bobber to stay above the rocks and to find the eddies. Once a float gets in an eddy it will circle around, which is perfect because the eddy is where baitfish and predator fish are holding. The bite usually happens quickly.ï¿½
Equipment includes his signature series 10-foot spinning rod, a float and a YUM F2 Wooly Beavertail jig. He prefers using one jig but says a tandem jig rig is fine if you prefer. ï¿½My best tip: Donï¿½t overlook shallow water,ï¿½ he said. ï¿½Since oxygen levels are the same everywhere, spillway crappie may be very shallow where it is easier for them to ambush food. ï¿½Another great thing about a spillway is you might catch a pound crappie, and on the next cast a white bass, then a 3-pound walleye, a northern or one of the many other species there. Spillway fishing is a lot of fun.ï¿½
Boat docks are well known crappie magnets, but most boating crappie anglers hit the fronts and maybe halfway down the sides. During summer, especially early and late in the day, the bank-side of docks can be more productive. ï¿½Fish can be at many different locations on a dock but the backside can have the right depths and cover for this time of year,ï¿½ said Morrow. ï¿½Fishing from the bank will put you in the action.ï¿½
Morrow casts and pitches using 7- or 10-foot poles spooled with 6- or 8-pound test Silver Thread line. The shorter pole is good for casting and flipping while the 10-foot Huckabee spinning rod is good for vertical dipping, pitching and casting.
Rigs can vary based upon your favorite baits. Morrow says his choice easy. ï¿½I use a Lindy Crappie Cork because I can fish any depth by adjusting it up or down and I can cast it for distance and accuracy. Under the float I like a 1/16-ounce Fuzzy Grub or 1/8-ounce Watsit jig in a natural color. Green pumpkin has always worked well for me in late summer. If the water is super-clear or the fish run on the small side, use a smaller jig.
ï¿½I target brushpiles and cover near the backsides of the docks. Sometimes you can see them but most of the time youï¿½ll have to find them by retrieving your bait between the dock and bank. Keep raising the slip float to put the bait deeper until you find cover.ï¿½
Caleb Newton, a Spotsylvania County, VA resident, plumber and die-hard fisherman, has snagged a world record.
Within a few days, the Stafford County native will be able to hang the evidence on the wallï¿½a certificate from the International Game Fish Association, confirming he caught a 17 pound, 6 ounce monster northern snakehead in Aquia Creek on June 1. The previous record, 17 pounds, 4 ounces, was caught in Miki Kagawa, Japan in 2004.
ï¿½His record has been approved and weï¿½ll be sending the certificate later
this week or early next week,ï¿½ Jack Vitek, world-record coordinator for the Florida-based IGFA, said Monday.
Vitek said that Newton will actually have two world records: the all-tackle record for the northern snakeheadï¿½a predatory invasive fish that has spread from the Potomac River to other Chesapeake Bay riversï¿½and the record for the 20-pound line class. The world-record certificate is the same one sent to IGFA record holders on more than 1,000 fish species.
Newton, 27, was fishing with Stafford buddy Phil Wilcox on Aquia Creek that day, in a tournament with 15 other boats.

To keep pace with a rapid schedule and increasing demand, the USGS has posted new US Topo quadrangles covering Indiana(640 maps), Iowa (1,011 maps), North Carolina (833 maps), Pennsylvania (798 maps) and Virginia (596 maps) online.
These new quads replace the first edition US Topo maps for those states. The replaced maps will be added to the USGS Historical Topographic Map Collection and are also available for free download from The National Map and the USGS Map Locator & Downloader website.
"The newly redesigned US Topo maps are visually appealing, especially with the addition of the shaded relief layer", explained Bob Davis, the new US Topo Project Manager. "The addition of shaded relief and other design components demonstrate our commitment to improving the product to meet our usersï¿½ needs. I encourage you to download these maps, compare them against previous US Topo maps and drop us your comments. We value your input."
US Topo maps now have a crisper, cleaner design - enhancing readability of maps for online and printed use. Map symbols are easier to read over the digital aerial photograph layer whether the imagery is turned on or off. Improvements to symbol definitions (color, line thickness, line symbols, area fills), layer order, and annotation fonts are additional features of this supplemental release. Users can now adjust the transparency for some features and layers to increase visibility of multiple competing layers.
Re-design enhancements and new features:
● Crisper, cleaner design improves online and printed readability while retaining the look and feel of traditional USGS topographic maps
●New functional road classification schema has been applied
● A slight screening (transparency) has been applied to some features to enhance visibility of multiple competing layers
● Updated free fonts that support diacritics
● New PDF Legend attachment
● Metadata formatted to support multiple browsers
● New shaded relief layer for enhanced view of the terrain
● Military installation boundaries, post offices and cemeteries
U.S. Topo maps are created from geographic datasets in The National Map, and deliver visible content such as high-resolution aerial photography, which was not available on older paper-based topographic maps. The new US Topo maps provide modern technical advantages that support wider and faster public distribution and on-screen geographic analysis tools for users.
The new digital electronic topographic maps are delivered in GeoPDF image software format and may be viewed using Adobe Reader, available as a no cost download. For more info: http://nationalmap.gov/ustopo/
Lower than average temperatures prevailed in the Great Lakes basin last weekend and early this workweek. However, temperatures were generally at or slightly above average on Tuesday and Wednesday. Some significant precipitation fell in the Great Lakes on Tuesday and Wednesday. So far for the month of August, all of the Great Lakes are above their average precipitation amounts. Most of the region will see temperatures near seasonal averages over the next several days. There is a strong chance of showers throughout the region through Friday, followed by partly sunny skies for most of the weekend.
LAKE LEVEL CONDITIONS
The water levels of Lakes Superior and Michigan-Huron are 7 and 4 inches respectively, above their levels from this time last year. Lakes St. Clair, Erie, and Ontario are 6, 9, and 14 inches, respectively, above their levels of a year ago. Over the next month, Lake Superior is forecasted to remain near its current level and Lake Michigan-Huron is expected to decline 1 inch. Lake St. Clair is expected to fall 2 inches over the next month while lakes Erie and Ontario are predicted to fall 5 and 7 inches, respectively.
FORECASTED MONTHLY OUTFLOWS/CHANNEL CONDITIONS
Lake Superiorï¿½s outflow through the St. Marys River is projected to be above average for the month of August. Lake Huronï¿½s outflow into the St. Clair River and the outflow from Lake St. Clair into the Detroit River are
also expected to be below average throughout the month of August.
Lake Erieï¿½s outflow through the Niagara River is predicted to be near average and the outflow of Lake Ontario into the St. Lawrence River is expected to be below average in August.
Official records are based on monthly average water levels and not daily water levels. Users of the Great Lakes, connecting channels and St. Lawrence River should keep informed of current conditions before undertaking any activities that could be affected by changing water levels. Mariners should utilize navigation charts and refer to current water level readings.

Minnesotaï¿½s waterfowl season will open a half-hour before sunrise on Sept. 21 and continue for 60 days under a north, central and southern zone structure with different season dates for each zone, according to the Minnesota DNR. This is the same structure the DNR used for the first time last year. The opener is one day earlier than last year and the earliest since 1945.
ï¿½Hunters had a good waterfowl season last year,ï¿½ said Paul Telander, DNR wildlife section chief. ï¿½We heard positive reports so we maintained the same season structure.ï¿½
The daily bag limit remains at six ducks per day. The mallard bag limit remains at four per day, including two hen mallards. The wood duck bag limit will remain at three per day. The only bag limit changes from last year are the daily limit for scaup which drops from four to three per day and the canvasback limit increases from one to two per day.
Telander said the other notable change is possession limits have increased from two times the daily bag limit to three times the daily bag limit for all migratory birds. The U.S. Fish and Wildlife Service offered the increase to all states. Telander also noted this yearï¿½s opening date is based on a federal framework that enables Mississippi Flyway states to open their season on the Saturday nearest Sept. 24 each year. Next yearï¿½s season could open no earlier than Sept. 27.
Mallard abundance from a continental spring survey, including Minnesota, is used to determine overall duck season length. This yearï¿½s estimate was 10.4 million mallards, which was similar to last yearï¿½s estimate of 10.6 million mallards and 36 percent above the long-term average.
Steve Cordts, DNR waterfowl specialist, said breeding duck numbers were good for mallards and all other duck species this year and wetland conditions in the major waterfowl breeding areas were also favorable. ï¿½In Minnesota, the population index of resident breeding mallards was also good, with an estimated 293,000 mallards in our survey area, Cordts said. ï¿½Thatï¿½s 30 percent above the long-term average.ï¿½
Duck harvest in Minnesota last fall was up 19 percent from 2011, from 621,000 ducks in 2011 to 749,000 ducks in 2012. Most of the increase was due to increased harvest of blue-winged teal and wood ducks. ï¿½Weï¿½ve made some changes with duck hunting regulations the past few years to increase harvest opportunity, particularly early in the season,ï¿½ Cordts said. ï¿½These changes seem to have worked as we have seen increased harvest of early migrating species like teal and wood ducks.ï¿½
YOUTH WATERFOWL DAY
OPEN WATER HUNTING
These new opportunities are an outcome of a DNR-led waterfowl hunter focus group and citizen input process. Lake Superior, Lake of the Woods, Mille Lacs Lake, and Lake Pepin will be open to open water hunting as long as boats remain at anchor. On the Mississippi River south of Hastings, with the exception of Lake Pepin, hunters must remain within 100 feet of shoreline, including islands. This matches the Wisconsin regulations on this portion of the river. Hunters should consult the 2013 Waterfowl Regulations for additional information.
Maj. Phil Meier, DNR enforcement operations manager, said these new open water hunting opportunities will require extra safety precautions. ï¿½Hunters should wear their life jackets not just have them aboard,ï¿½ Meier advised, noting this type of hunting involves small shallow boats and some of Minnesotaï¿½s largest and most windswept lakes. ï¿½Theyï¿½ll also have to be on the lookout for recreational boaters, large waves from barges and other commercial traffic and unfavorable changes in the weather. Itï¿½s a different type of hunting; it takes a different safety mindset.ï¿½
A $4 permit is required to hunt Canada geese during September season. The restriction prohibiting hunting within 100 yards of surface water remains in effect in the Northwest Goose Zone, Carlos Avery Wildlife Management Area, Ocheda Lake Game Refuge, and an area surrounding Swan Lake in Nicollet County. Early season goose hunters should consult the 2013 Waterfowl Supplement for zone maps and additional details.
Regular goose season
Sandhill Crane Season
Additional details on the duck, goose, sandhill crane, and other migratory bird hunting seasons will be available in the 2013 Minnesota Waterfowl Hunting Regulations, available in mid-August on online at www.dnr.state.mn.us.
To protect NY and Great lakes
The New York State Department of Environmental Conservation (DEC) has made changes pertaining to the regulations governing the import, transport, possession and sale of bighead carp, and are now in effect. The amended regulations ban the importation, possession and sale of live bighead carp in all of New York State.
As an invasive species, bighead carp are a serious threat to the stateï¿½s aquatic communities and much effort is being expended by federal and Great Lakes state agencies to prevent these fish from gaining access to the Great Lakes basin via the Mississippi River system.
Previously, New Yorkï¿½s regulations prohibited the possession and sale of fish species that DEC had determined to be a present danger to
indigenous fish populations, including snakehead fish and three species of
Asian Carp (including bighead carp). However, until now, the prohibitions included an exception that allowed bighead carp to be sold, possessed, transported, imported and exported in the five boroughs of the City of New York (Manhattan, Bronx, Queens, Brooklyn, and Staten Island) and the Westchester County towns of Rye, Harrison, and Mamaronek and all the incorporated cities or villages located therein.
As a result of federal action, all interstate transportation of live bighead carp was banned, so the exceptions in DECï¿½s regulations that provided for limited sale of bighead carp for human consumption, required repeal. The amended regulations eliminate any possible confusion regarding the legal status of this species in New York, and will bolster efforts to prevent the spread of bighead carp into the Great Lakes states.
