WEST LAFAYETTE, Ind. - The Earth may be able to recover from rising carbon dioxide emissions faster than previously thought, according to evidence from a prehistoric event analyzed by a Purdue University-led team. When faced with high levels of atmospheric carbon dioxide and rising temperatures 56 million years ago, the Earth increased its ability to pull carbon from the air. This led to a recovery that was quicker than anticipated by many models of the carbon cycle - though still on the order of tens of thousands of years, said Gabriel Bowen, the associate professor ...

What is a dental bridge? A dental bridge is a solution for missing teeth. Using a false tooth, a dental bridge is attached to two porcelain crowns and affixed to your adjacent teeth to hold it into place. Once in place, the false tooth restores symmetry, function, and beauty to your smile. Can a dental bridge be used to replace several teeth? Depending on how many teeth you need to have replaced, there are three different types of dental bridges. Traditional fixed bridges and cantilever bridges can be used to replace several missing teeth at one time. Resin-bonded ...

Do you belong to the one-half of the population that frequently uses dietary supplements with the hope that it might be good for you? Well, according to a study published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, there seems to be an interesting asymmetrical relationship between the frequency of dietary supplement use and the health status of individuals. Wen-Bin Chiou of National Sun Yat-Sen University decided to test if frequent use of dietary supplements had ironic consequences for subsequent health-related ...

Headaches are one of the more common medical complaints people have. Headaches can range from annoying to debilitating. Another problem with headaches is that they can be chronic, returning day after day. Despite their frequency, it can be very hard to track down the cause of headaches. If you have been to one or more doctors to seek help with your headaches, but have been able to get a true diagnosis and successful headache treatment, perhaps you need to go in a different direction. Perhaps you need a dentist. Could Your Teeth Be Causing Your Headaches? Where ...

What tales they tell of their former lives, these old bones of sirenians, relatives of today's dugongs and manatees. And now, geologists have found, they tell of the waters in which they swam. While researching the evolutionary ecology of ancient sirenians--commonly known as sea cows--scientist Mark Clementz and colleagues unexpectedly stumbled across data that could change the view of climate during the Eocene Epoch, some 50 million years ago. Clementz, from the University of Wyoming, published the results in a paper in this week's issue of the journal Science. He ...

All women have uneven breasts, but the difference can be so pronounced in many women as to create difficulty finding bras and clothes that fit properly. Extreme breast asymmetry can also lead to feelings of insecurity and depression about your appearance. The difference between breasts can be subtle in some women, dramatic in others; it can also include corresponding conditions such as uneven nipples, varying areolas or differently shaped breasts. The causes of uneven breasts can also differ. Asymmetrical breasts can be genetic in nature or brought about by hormonal ...

Maryland Court of Appeals Upholds Statutory Damages Cap Last year brought one significant disappointing legal development for Maryland personal injury victims and wrongful death survivors. While plaintiffs in Illinois and Georgia received news from their state's highest courts that damages should be determined by juries rather than politicians, the Maryland Court of Appeals issued an opinion that upheld the cap on damages passed by the state legislature over two decades ago. Insurance companies and other "tort reform" advocates were understandably pleased with ...

Athens, Ga. – Researchers at the University of Georgia and Yale University have discovered a compound with the potential to be more effective than existing agents in treating the very painful blisters known as shingles—a condition that affects up to 30 percent of Americans, mostly elderly, and for which no specific treatment exists. Most adults remember the fever, itchy blisters and possibly tiny scars they experienced as children when they had chickenpox, which is caused by the varicella-zoster virus, or VZV.Unfortunately, that memory can come back—with a vengeance—when ...

North Carolina Appeals Court Reverses Workers' Compensation Award A recent North Carolina Court of Appeals opinion took a close look issues of medical causation and liability in North Carolina workers' compensation cases. The case, Gross v. Gene Bennett Co., involved a claim for workers' compensation benefits from a welder and steel fabricator who injured his back after falling through a suspended ceiling over ten feet to a concrete floor. The plaintiff initially missed about two months of work after receiving medical treatment and occupational therapy and receiving ...

UCLA researchers have redefined the concept of a microscope by removing the lens to create a system that is small enough to fit in the palm of a hand but powerful enough to create three-dimensional tomographic images of miniscule samples. The advance, featured this week in the early online edition of the journal Proceedings of the National Academy of Sciences, represents the first demonstration of lens-free optical tomographic imaging on a chip, a technique capable of producing high-resolution 3-D images of large volumes of microscopic objects. "This research clearly ...

High-Profile California Cases Draw Attention to Employee Misclassification Recent lawsuits filed in California courts against Franklin American Mortgage Company, Raytheon, Enterprise Rent-A-Car and Ecolab are highlighting the oft-ignored issue of employee misclassification. The intentional -- or even accidental -- misclassification of employees can make them ineligible for payment of overtime benefits, mandatory rest periods, covered meal times, uniform reimbursement and other employee perks. California Overtime Payment Laws California has some of the most employee-friendly ...

New research on mice has shown that pulmonary administration of granulocyte macrophage-colony stimulating factor (GM-CSF) significantly reduces flu symptoms and prevents death after a lethal dose influenza virus. While GM-SCF therapy for humans as a flu prophylaxis or treatment may be years away, the study results were striking: All of the mice treated with GM-SCF survived after being infected with the influenza virus, whereas untreated mice all died from the same infection. "Such unique and unambiguous results demonstrate the great potential of GM-CSF and may be the ...

Scotland's first fully protected marine reserve, and only the second in the UK, is already providing commercial and conservation benefits, according to new research. After only two years in operation, it is already showing positive signs for both fishermen and conservationists, according to a study by the University of York and the Community of Arran Seabed Trust (COAST). The research, published in the journal Marine Biology, shows that commercially valuable scallops and several species of algae known to promote biodiversity are much more abundant in the marine reserve, ...

PHOENIX, Ariz.-- April 22, 2011-- A gene called PVT1 may help reduce the kidneys ability to filter blood, leading to kidney disease, kidney failure and death, according to a study published today by researchers at the Translational Genomics Research Institute (TGen). The TGen team found PVT1 expression levels increased up to 5-fold in response to hyperglycemia, or high blood sugar, a condition that often accompanies diabetes. But by knocking down or reducing the expression of the PVT1gene, TGen researchers lowered the amount of proteins associated with the excessive ...

An article in Science Signaling by researchers at the RIKEN Research Center for Allergy and Immunology (RCAI) has clarified for the first time the mechanism governing differentiation of B cells into antibody-producing plasma cells. The finding establishes a role for the extracellular signal-regulated kinase (ERK) signaling pathway in B cell differentiation, a key step toward the development of B cell-targeted drugs for treatment of autoimmune diseases and allergies. As the only cells in the body that produce antibodies, B cells play an essential role in the immune system's ...

Dallas Man Petitions Texas Supreme Court for Review of Gay Divorce Case Texas is one of several states that have amended their constitutions to limit legal recognition of marriage to one man and one woman. Same-sex couples who want to formalize certain aspects of their relationship can explore Texas domestic partnership solutions, including adoption, cohabitation agreements and designation of end-of-life rights. But given that other states have formally recognized gay marriage, many Texans have traveled to places like Iowa and Massachusetts to obtain a legal marriage. If ...

PHILADELPHIA--During embryonic development, cells migrate to their eventual location in the adult body plan and begin to differentiate into specific cell types. Thanks to new research at the University of Pennsylvania, there is new insight into how these processes regulate tissues formation in the heart. A developmental biologist at Penn's School of Veterinary Medicine, Jean-Pierre Saint-Jeannet, along with a colleague, Young-Hoon Lee of South Korea's Chonbuk National University, has mapped the embryonic region that becomes the part of the heart that separates the outgoing ...

Mortgage Fraud and the Financial Crisis In Oregon and across the country, the fallout from the subprime mortgage collapse and the ensuing financial meltdown has still not ended. This fallout does not only include depressed housing values and the seemingly endless waves of foreclosures that have affected so many lives. It also includes the unfairness of bringing mortgage fraud cases against people who were rank-and-file players in the deregulated mortgage industry. Mortgage fraud is a serious charge that often requires a vigorous federal criminal defense. Systemic ...

Michigan Crime and Punishment for Reckless or Drunk Driving Two fiery Michigan crashes lead to very different charges. In 2009, Robert Gorter crashed his car into a truck in a construction zone on I-196. Authorities say he was driving too fast for the conditions when he struck the truck. Both the car and the truck caught fire and the truck was pushed down an embankment. Gorter's 83-year-old wife and the 70-year-old driver of the truck were killed instantly. In 2010, Lauraetta Carey pursued her boyfriend and his female companion at speeds of up to 100 mph before he ...

Humans are not born as blank slates for nature to write on. Neither are they behaving on genes alone. Research by Lee A. Thompson, chair of Case Western Reserve University's Psychological Sciences Department, and colleagues found that the link between Attention-Deficit/Hyperactivity Disorder (ADHD) and academic performance involves a complex interaction of genes and environment. Genetic influence was found to be greater on reading than for math, while shared environment (e.g., the home and/or school environment the twins shared) influenced math more so than reading. ...

The University of Connecticut and California State University researchers found that seafloor communities in a restricted fishing area in NOAA's Stellwagen Bank National Marine Sanctuary showed indications of recovery from chronic fishing gear impacts but is not fully stable. The finding is significant because bottom trawlers, dredges and certain gillnets, for example, can alter the ocean floor and benthic ecosystems that provide food and shelter for fish and other marine species. The Western Gulf of Maine habitat closure area overlaps 22 percent of the sanctuary and ...

The exponentially increasing amount of digital information, along with new challenges in storing valuable data and massive datasets, are changing the architecture of today's newest supercomputers as well as how researchers will use them to accelerate scientific discovery, said Michael Norman, director of the San Diego Supercomputer Center (SDSC) at the University of California, San Diego (UCSD). In a presentation during the 3rd Annual La Jolla Research & Innovation Summit this week, Norman said that the amount of digital data generated just by instruments such as DNA ...

The Long Term Effects of Post-Concussion Syndrome (PCS) Only recently have the serious consequences of concussions become generally understood. Muhammad Ali and his Parkinson's disease is a popular and extreme case of someone living with a brain injury from a (or a series of) sports related concussion. However, research shows that even non-professional athletes can suffer unseen injuries from common accidents that may last a lifetime. A concussion is a mild traumatic brain injury generally caused by a blow to, or the rapid back and forth movement of, the head. While ...
