Give green light to new energy era

Wisconsin State Journal

Neither Wisconsin’s economy nor its environment can thrive for long if the state continues to depend so overwhelmingly on nonrenewable, imported energy sources that contribute to climate change.

That warning should enlighten policymakers and voters as the debate accelerates over the recommendations from Gov. Doyle’s Global Warming Task Force.

Professor creates microscope program for elementary school kids

Milwaukee Journal Sentinel

When Doug Weibel spotted an $85 microscope at Toys â??Râ? Us, he immediately bought it and brought it home for his children. His children started magnifying everything they could get their hands on – wires, sponges, insects – capturing images and recording movies on a computer linked to the microscope.

It struck Weibel, however, that this was not only fun, but also educational.

Last December, Weibel, an assistant professor of biochemistry at the University of Wisconsin-Madison, decided to start an outreach program called MicroExplorers to bring microscopes to classrooms and after-school activities.

Lawmakers must recognize value of higher education (Eau Claire Leader-Telegram)

UW-Madison has lost a key environmental researcher to the University of Minnesota.

If this was an isolated case, it would be one thing. But this has happened before. And it will happen again as long as salaries for UW campuses do not keep up with peer institutions.

And it will keep up as long as there is wrong-headed anti-university actions taken by legislators from both political parties.

Madison Puzzled Over Biolab Site Placement

Wisconsin Public Radio

New light has been cast on the selection process for a national, multi-million dollar biolab facility, which included Wisconsin. Documents obtained and reviewed by the Associated Press show that the favored site chosen for the lab ranked much lower than the Badger State and five others. Brian Bull reportsâ?¦(Audio.)

Farms can increase wildlife diversity, Wisconsin researchers say

Milwaukee Journal Sentinel

Farms cover nearly half the land in Wisconsin, creating an immense stress on the natural biodiversity of the stateâ??s landscape.

But farms can also drastically increase the diversity of plants, birds and beneficial insects by incorporating uncultivated land, University of Wisconsin-Madison scientists reported this week at the Ecological Society of Americaâ??s annual meeting in Milwaukee.

Airless Tire Promises Grace Under Pressure for Soldiers

Scientific American

To keep troops from being stranded and easily ambushed on the battlefield, the Army is working with researchers to develop tires for their Humvees that can better withstand roadside attacks. One such design comes from Resilient Technologies, LLC, based in Wausau, Wis., and the University of Wisconsinâ??Madison’s Polymer Engineering Center. With a four-year, $18-million grant from the Pentagon, Resilient is working to create a “non-pneumatic tire” (NPT) technology, called that because it doesn’t require air.

Low Vitamin D levels lead to early death for many Wisconsinites, says study

WIBA Newsradio

Wisconsinites have a higher risk of death than people living in southern states because we get less Vitamin D due to our lower exposure to the sun, according to a new study.

Albert Einstein College in New York tracked 13,000 people in their 40â??s for about nine years. Those with the lowest Vitamin D levels had a 26 percent greater chance of dying early than those with the highest levels.

Itâ??s not unusual for Wisconsinites to have Vitamin D levels in the low range, especially when itâ??s not summer. Neil Binkley of UW-Madison says Vitamin D deficiency is an epidemic in many parts of the world, including ours.

‘Critical time’ for UW Arboretum

Wisconsin State Journal

When Aldo Leopold spoke on June 17, 1934, at the dedication of the UW Arboretum, he stood in the middle of two square miles of derelict farmland.
There was no rumble of traffic from the Beltline because the Beltline did not exist. To the south was nothing but more farmland. There were a few housing developments nearby but mostly the city and the Arboretum’s parent university were miles away across more fields and woodlots.

Curiosities: Electromagnets propel hovering maglev trains

Politics Interfering With NBAF Lab Decision (AP)

CBSNews.com

The Homeland Security Department swept aside evaluations of government experts and named Mississippi – home to powerful U.S. lawmakers with sway over the agency – as a top location for a new $451 million, national laboratory to study some of the world’s most virulent biological threats, according to internal documents obtained by The Associated Press.

Mississippi’s lawmakers include the Democratic chairman of the department’s oversight committee in the House and the senior Republican on the Senate Appropriations Committee, which is expected to approve money to build the National Bio and Agro-Defense Facility at one of five sites being considered. The two lawmakers said they were unaware of the Homeland Security evaluation system that scored the Mississippi site so low.

The disclosure is the latest example of what critics assert is the Bush administration’s politicizing of government decisions, such as efforts to steer science over global warming at the Environmental Protection Agency and hiring and firing practices at the Justice Department.

“It is very suspicious,” said Irwin Goldman of the University of Wisconsin, a leader of the unsuccessful effort to build the lab in Madison. His community’s offer was among nine sites rejected even though the government scored it more highly than Mississippi’s. “We wondered how everybody else did. It’s interesting to know that we came out ahead of one that was short-listed.”

Scientists produce stem cells for 10 diseases

USA Today

Harvard scientists say they have created stems cells for 10 genetic disorders, which will allow researchers to watch the diseases develop in a lab dish.

This early step, using a new technique, could help speed up efforts to find treatments for some of the most confounding ailments, the scientists said.

Harvard scientists create new stem cell lines

Milwaukee Journal Sentinel

Harvard scientists have reprogrammed the cells of patients with various genetic illnesses back to an embryonic state, creating a bank of cells that researchers can use to study and fight disease.

The 20 new cell lines span 10 different diseases and conditions, including Parkinsonâ??s and Down syndrome. They will offer scientists the chance to watch diseases progress in a laboratory dish and give researchers new targets for drugs

Harvard Team Makes 10 Disease-Bearing Stem Cell Lines

Bloomberg News

Harvard University scientists have made lines of stem cells, able to turn into any other cell in the body, from bits of skin or blood of 10 patients with genetic diseases including muscular dystrophy and juvenile diabetes.

The findings will help researchers decipher the workings of these diseases, enabling them to study what happens as cells that carry a condition’s genetic seeds develop and age. The lines will be made available for a “nominal fee” to researchers around the world, the Harvard scientists said.

Not to worry

Isthmus

According to a new UW-Madison study, the prions that cause mad cow disease are not destroyed by conventional sewage treatment and could end up contaminating water and fertilizer. This may be of interest to folks ’round here, given that the state Department of Natural Resources has for the past few months been dumping the carcasses of deer with chronic wasting disease (CWD) in the county’s Rodefeld landfill, from which leachate is pumped into the sewerage treatment plant.

But, it turns out, there’s absolutely nothing to worry about!

UW-Madison Opens Newest Dairy Facility

Ag Weekly (Twin Falls, ID)

It has been a long road, but one goal of the UW-Madison Dairy Science Department is now reality. The newest addition to UW-Madisonâ??s dairy facilities dedicated to serving Wisconsinâ??s and the nationâ??s dairy producers, was officially dedicated last week on location in Arlington.

â??It has been a relatively long journey for our department and college,â? noted Ric Grummer, Dairy Science Department chairperson. But the department now has an elite facility for research to prove that it is the premier dairy science department and school in the country.

The new facility is located on Badger Lane outside of Arlington. It includes a parlor and two freestall barns that are all specially geared to foster research projects in an environment that closely resembles a typical dairy operation today.

The grant will also help efforts to build and refine techniques for growing large amounts of embryonic stem cells.

City hoping UW incubator can spark East Rail Corridor

Capital Times

UW-Madison Chancellor John Wiley and Mayor Dave Cieslewicz meet for lunch from time to time to keep each other informed about all that’s going on around town.

It was about a year ago during one of these get-togethers that Wiley talked about his hopes of developing an urban research park — targeting high-technology entrepreneurs — on East Washington Avenue.

“And I dropped my dessert fork,” Cieslewicz recalled Monday. “And I said, ‘Chancellor, if there is anything we can do to make that happen, we want to make that happen.’ ”

On Monday, University Research Park Director Mark Bugher announced plans to open a new urban campus in 6,000 square feet of space leased in the former Marquip Building at 1245 E. Washington Ave., which is just more than a mile from the Capitol Square.

UW Research Park To Expand On East Side

WISC-TV 3

MADISON — The University of Wisconsin Research Park is looking to expand, and officials are eyeing a historic property on Madison’s East Side.

The new urban research park would be housed inside the Marquip Building, a Madison landmark that has been vacant for more than five years.

“Some would say, ‘Why here in this location?'” said Mark Bugher, director of the research park. “First and foremost, it’s close to the UW campus, close to the (Madison Area Technical College) campus. It’s a vibrant edgy neighborhood.”

MADISON â?? Most of the 115 businesses in the University Research Park on the Capital Cityâ??s west side are biotech companies that require wet labs for their ongoing experiments and product development.

But in the researchâ??s park urban expansion in the former Marquip Building at 1245 E. Washington Ave., the targets for the 10 new incubator suites in the former manufacturing site will be high-tech entrepreneurs working in the areas of information technology, engineering, medical devices and computer sciences.

The effort is starting out small, with a lease of 6,000-square feet. But it has the potential to â??explodeâ? within a few years as faculty members and students start their own businesses, said UW-Madison Chancellor John Wiley.

Gov says no to coal for state power plants

Capital Times

Using coal at state-owned heating plants is not an option that should be considered as a fuel source, according to a directive issued Friday by Gov. Jim Doyle.

The directive to move away from coal is in line with recommendations made by the governor’s task force on global warming.

“The state should lead by example and move away from our dependence on coal at the state-owned heating plants in Madison,” Doyle said. “Global warming demands leadership, and as we plan for the future of the Madison heating facilities, we must chart a course that lowers greenhouse gas emissions and encourages new alternative energy sources.”

Wis. governor says no to coal for power plants

Associated Press

MADISON, Wis. (AP) — Gov. Jim Doyle says the state should lead by example and move away from using coal at state-owned power plants in Madison.

Doyle said Friday the state must lower greenhouse gas emissions and encourage new alternative energy sources. The governor’s comments come after a global warming task force he created called for dramatically cutting greenhouse gas emissions.

A study released Friday looked at 13 options for the three existing state-owned heating plants in Madison. State and University of Wisconsin officials are examining the options to determine which are the best for heating and cooling buildings.

The study was part of a deal reached in a settlement last year in a lawsuit that uncovered pollution violations at a university power plant.

Sleep apnea hikes risk of death, UW study finds

Capital Times

A new study conducted by a team of University of Wisconsin researchers shows that people suffering from severe sleep apnea have three times the risk of dying due to any cause compared to people without the disorder.

Sleep apnea is a condition with repeated episodes of breathing pauses during sleep despite an ongoing effort to breathe. Apnea often occurs when muscles in the back of throat relax, causing soft tissue to collapse and temporarily block the air passage.

The study, published in the Aug. 1 issue of Sleep, was led by Dr. Terry Young, professor of epidemiology at UW-Madison’s School of Medicine and Public Health.

Even surgery doesn’t stop alcoholics’ habits (Reuters Health)

MSNBC.com

NEW YORK – Life-saving surgery to prevent repeated severe bleeding from ruptured veins in the esophagus or upper stomach may not induce some patients with alcoholic liver disease to stop drinking alcohol, researchers report.

Such a surgical procedure may be necessary to reduce the pressure in the veins of the esophagus and upper stomach among patients with cirrhosis, a scarring of the liver frequently caused by alcohol abuse.

The study group consisted of 132 patients with cirrhosis, including 78 with alcoholic liver disease, lead author Dr. Michael R. Lucey, of the University of Wisconsin School of Medicine and Public Health, and colleagues report.

Biological fathers not always the best

MADISON, Wis., Aug. 1 (UPI) — Married social fathers exhibited equal or better quality parenting behaviors than married and cohabiting biological fathers, a U.S. study found.

The study, published in the Journal of Marriage and Family, found that married and cohabiting biological fathers displayed relatively similar quality parenting and the parenting practices of married social fathers were of higher quality than those of cohabiting social fathers.

Study leader Lawrence M. Berger of the University of Wisconsin-Madison said married social fathers were more engaged with children, took on more shared responsibility in parenting and were more trusted by mothers to take care of children.

Sleep apnea boosts death risk, study finds (AP)

CNN.com

People with the severe form of apnea, which interferes with sleep, are several times more likely to die from any cause than are folks without the disorder, researchers report in Friday’s edition of the journal Sleep.

In the new report, the Wisconsin Sleep Cohort followed 1,522 men and women, ages 30 to 60. The annual death rate was 2.85 per 1,000 people per year for people without sleep apnea.

People with mild and moderate apnea had death rates of 5.54 and 5.42 per 1,000, respectively, and people with severe apnea had a rate of 14.6, researchers said.

Cardiovascular mortality accounted for 26 percent of all deaths among people without apnea and 42 percent of the deaths among people with severe apnea, according to the researchers led by Terry Young of the University of Wisconsin, Madison.

Business Beat: Weak dollar boosts biotech buyouts

Capital Times

There has been plenty of excitement on the local biotechnology scene, with three local start-ups acquired in the past 13 months.

The most recent deal has the Swiss pharmaceutical company Roche Holdings paying $125 million for Madison-based Mirus Corp. Established in 1995 based on the gene therapy work of UW-Madison scientists, Mirus has about 60 total employees here who are expected to keep their jobs.

Last June, Roche also purchased NimbleGen, a privately held Madison-based genomics company, for $272.5 million. NimbleGen has about 90 employees here. And earlier this summer, Boston-based Hologic Inc. announced a $580 million acquisition of Madison-based Third Wave Technologies that was just recently completed.

The deals have been widely cheered by the local biotech industry, and why not? It sure beats the drumbeat of job cuts and plant closings, the latest from Synergy Web Graphics in Mazomanie and Stoughton

New UW-Madison dairy complex now open for business

Capital Times

ARLINGTON — Several hundred guests gathered at the UW-Madison Arlington Agricultural Research Station to get their first peek at the newly opened dairy barn and milking facility.

The $5.1 million dairy complex includes two freestall dairy barns, a Double 16 WestfaliaSurge milking parlor, a sand bedding recycling system and 350 dairy cows that are milked twice a day. Soon 450 cows will make their home there.

But the dedication ceremony Wednesday was about more than the technology and details incorporated into the modern dairy facility — there are many other barns similar to this one across the state. It was also about the unusual road taken to get the much-needed facility built.

Sparing leukemia patients from unnecessary chemo (Reuters)

National Post (Canada)

NEW YORK (Reuters Health) – Nearly one-third of leukemia patients do not respond to chemotherapy, but this is not typically discovered until they have already endured a week-long course of chemotherapy and waited even longer to see if the chemotherapy worked.

A new study shows that positron emission tomography, known as PET scans, may tell doctors how well a leukemia patient is responding after just one day of chemotherapy.

“This has very profound implications for patients,” Dr. Matt Vanderhoek told Reuters Health. “Instead of making the patient go through a week of chemotherapy only to find out after the fact that their chemotherapy wasn’t successful, therapy could be modified and changed on the fly.”

The University of Wisconsin researcher will present the research Thursday at the 50th annual meeting of the American Association of Physicists in Medicine, underway in Houston, Texas.

Consent row threatens stem cell research

New Scientist

The ethical quagmire surrounding human embryonic stem cell research is getting even stickier.

It seems that some of the cell lines sanctioned for use by the current US administration may have been obtained without proper consent from the women who provided the original embryos. The ethical storm could halt some federally funded stem cell research.

But Robert Streiffer, a bioethicist at the University of Wisconsin-Madison, has now obtained the original consent documents from the NIH using the federal Freedom of Information Act.
