Simple recommendations help reduce environmental exposures for women

Remove your shoes at the door of your home to avoid tracking in pollutants. Decrease consumption of processed and canned foods. Avoid the use of plastics with recycling codes #3, #4 and #7. Don't use chemical tick and flea collars or dips for pets. Reproductive health care providers should share these tips and more scientific information with women who want to become pregnant or who are pregnant, but that does not always happen.

X-rays help decipher how natural antibiotics defy a longstanding set of chemical rules

Researchers working at the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory have used powerful X-rays to help decipher how certain natural antibiotics defy a longstanding set of chemical rules - a mechanism that has baffled organic chemists for decades.

Diesel exhaust fumes linked to lung cancer among miners

It has been known that diesel exhaust may be a probable carcinogen. But the 20-year study from the National Cancer Institute took a closer look in the Diesel Exhaust in Miners Study, which followed 12,315 miners working in eight underground nonmetal mining facilities. Data were collected on the miners' health and exposure to various elements and chemicals from the time when the mine company first introduced diesel-powered equipment (between 1947 and 1967) until the end of the study in 1997. They breathed varying levels of exhaust from diesel-powered equipment, levels higher than the general population encounters.

Sedentary women more prone to developing type 2 diabetes

A new study has found that women who stay seated for long periods of time every day are more prone to developing type 2 diabetes, but that a similar link wasn't found in men.

Combining two common cancer-fighting strategies may have 'tremendous synergy'

Researchers at the University of Illinois at Chicago College of Medicine have found that a molecule found at elevated levels in cancer cells seems to protect them from the "cell-suicide" that is usually triggered by chemotherapy or radiation.

Public agencies must study ecological risks of synthetic biology

Experts say at least $20 million to $30 million in government research is needed over the next decade to adequately identify and address the possible ecological risks of synthetic biology, an emerging area of research focused on the design and construction of new biological parts and systems, or modification of existing ones, to create new applications in areas ranging from energy to chemicals and pharmaceuticals.

Expertise guide to facilitate use of QSARs under EU REACH Program

Seeking to maximise the value of computational modelling in avoiding animal testing for the European Union's Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH), the People for the Ethical Treatment of Animals (PETA) Foundation has produced a free resource for chemical companies, identifying sources of information and expertise on the use of Quantitative Structure Activity Relationships (QSARs).

Study to make pesticide, methyl iodide safer

In 2007, a controversial pesticide was approved by the Food and Drug Administration for use on fruit and vegetable crops, mainly in California and Florida. Farm workers and scientists protested the approval of the pesticide because its active ingredient, methyl iodide, is a known carcinogen.

First clinical assessment of how interferon fights infections in people

A drug once taken by people with HIV/AIDS but long ago shelved after newer, modern antiretroviral therapies became available has now shed light on how the human body uses its natural immunity to fight the virus—work that could help uncover new targets for drugs.

LAU-0901 drug protects brain in an experimental stroke model

Research led by Nicolas Bazan, MD, PhD, Boyd Professor and Director of the Neuroscience Center of Excellence at LSU Health Sciences Center New Orleans, has found that a synthetic molecule protected the brain in a model of experimental stroke.

UVA, Johns Hopkins receive NIH grant to develop methods against glioblastoma

The most common primary brain cancer is glioblastoma, a highly aggressive and deadly form of tumor that kills about 95 percent of its victims within five years of diagnosis. Like other brain cancers, it is extremely difficult to treat because glioblastomas are usually deeply embedded within healthy brain tissue and therefore nearly impossible to safely access. Chemotherapy drugs cannot reach these tumors because a membrane between the bloodstream and brain tissue, called the blood-brain barrier, blocks them.

IU report supplies close examination of EU's reformed chemicals law

U.S. industry and environmental groups agree that the Toxic Substances Control Act (TSCA) of 1976 needs to be modernized to better protect public health and the environment. However, there is no consensus on what the reform should look like.

People with depression have increased connections among most brain areas

Most of us know what it means when it's said that someone is depressed. But commonly, true clinical depression brings with it a number of other symptoms. These can include anxiety, poor attention and concentration, memory issues, and sleep disturbances.

Seven scientists aim to make strides in predicting and preventing preterm birth

With the help of funding from the March of Dimes, researchers from five states and Canada are seeking answers to questions such as how cellular-level processes that control uterine muscles may affect preterm labor, the causes of preeclampsia, and how air pollution may affect pregnancy and preterm birth - all with the goal of preventing preterm birth so more babies will get a healthy start in life.

Researchers uncover how phytoplankton release powerful toxins into environment

Each year, phytoplankton blooms known as "red tides" kill millions of fish and other marine organisms and blanket vast areas of coastal water around the world. Though the precise causes of red tides remain a mystery, a team of researchers in the United States and Spain has solved one of the main riddles about these ecological disasters by uncovering the specific mechanism that triggers phytoplankton to release their powerful toxins into the environment.

Bath salts mimic effects of two powerful narcotics

The street drug commonly referred to as "bath salts" is one of a growing list of synthetic and unevenly regulated narcotics that are found across the United States and on the Internet. New research on this potent drug paints an alarming picture, revealing that bath salts pack a powerful double punch, producing combined effects similar to both methamphetamine (METH) and cocaine.

Radiation risk from Japan's nuclear disaster debris not a worry, but other aspects might be

The first anniversary is approaching of the March, 2011, earthquake and tsunami that devastated Fukushima, Japan, and later this year debris from that event should begin to wash up on U.S. shores - and one question many have asked is whether that will pose a radiation risk.

Bill to bar synthetic recreational drugs hits roadblock

A broadly popular bill by Sen. Amy Klobuchar, D-Minn., to outlaw synthetic recreational drugs across the nation has run into an increasingly common obstacle in the U.S. Senate: the objection of a single senator. Klobuchar and two other senators backing similar measures took the unusual step of taking to the Senate floor Wednesday to publicly denounce a "hold" placed on their bills by freshman Kentucky Republican Rand Paul. ... Paul spokeswoman Moira Bagley said he believes "law enforcement of most drug laws can and should be local and state issues."
