• 06:00 Unhappy customers: Everyone has a right to complain, and does

  Read the story at EurekAlert
  We've all had that sinking feeling when we got home and a purchase turned out to be damaged, or worse yet, we had no warranty with which to dispute the damage. Are some consumers disadvantaged by income, race, education, or age and therefore less likely to return that product for a refund or an exchange?

• 06:00 Unhealthy foods become less popular with increasing costs

  Read the story at EurekAlert
  Adults tend to eat less pizza and drink less soda as the price of these items increases, and their body weight and overall calorie intake also appear to decrease, according to a report in the March 8 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

• 06:00 University of Michigan scientists discover bone marrow can harbor HIV-infected cells

  Read the story at EurekAlert
  Antiviral drugs have reduced AIDS to more of chronic disease rather than a death sentence, but why is the disease so hard to cure? A study published online March 7 in Nature Medicine shows bone marrow, previously thought to be resistant to the virus, can contain latent forms of the infection. Targeting these reservoirs of latent cells may open the door to new treatments, according to scientists at the University of Michigan Health System.

• 06:00 Unselfish molecules may have helped give birth to the genetic material of life

  Read the story at EurekAlert
  One of the biggest questions facing scientists today is how life began. Scientists at Georgia Tech have discovered that small molecules could have acted as "molecular midwives" in helping the building blocks of life's genetic material form long chains and may have assisted in selecting the base pairs of the DNA double helix.

• 06:00 Violent crime 'race gap' narrows, but persists in US

  Read the story at EurekAlert
  The 'race gap' in the commission of violent crime has narrowed substantially yet persists , with murder arrest rates for African Americans out-distancing those for whites -- concludes a new 80-city study by the University of Maryland, Florida State University and the University of Oregon. While the gap was cut more than half in the 1970s, it re-grew in the '80s. The researchers find it most pronounced in communities with higher divorce, unemployment and drugs rates.

• 06:00 Warfarin users appear more likely to develop brain bleeding following stroke treatment

  Read the story at EurekAlert
  Patients already taking warfarin who develop an acute stroke appear more likely to experience a brain hemorrhage following treatment with an intravenous clot-dissolving medication, even if their blood clotting function appears normal, according to a report posted online today that will appear in the May print issue of Archives of Neurology, one of the JAMA/Archives journals.

• 06:00 Warning sign for potential anti-cancer approach

  Read the story at EurekAlert
  One treatment being investigated as an adjuvant for anticancer immunotherapies is the use of molecules that trigger the proteins TLR7 and TLR8. However, new research, to be published in the Journal of Clinical Investigation, suggests that such approaches should be developed with caution because stimulation of human lung cancer cells with TLR7 or TLR8 agonists increased tumor cell survival and resistance to chemotherapeutics.

  Read the story at EurekAlert
  Normal-weight women who drink a light to moderate amount of alcohol appear to gain less weight and have a lower risk of becoming overweight and obese than nondrinkers, according to a report in the March 8 issue of Archives of Internal Medicine, one of the JAMA/Archives journals.

• 06:00 A high-tech handrest

  Read the story at EurekAlert
  University of Utah engineers developed a computer-controlled, motorized hand and arm support that will let doctors, artists and others precisely control scalpels, brushes and tools over a wider area than otherwise possible, and with less fatigue.

• 06:00 All may look smooth, but there are 'bumps' along the way

  Read the story at EurekAlert
  Friction in human relations is all too obvious and prevalent, but friction in physics has had a "secret life" of its own that has now been revealed by scientists at the Hebrew University of Jerusalem.

• 06:00 Asking 'what would nature do?' leads to a way to break down a greenhouse gas

  Read the story at EurekAlert
  A recent discovery in understanding how to chemically break down the greenhouse gas carbon dioxide into a useful form opens the doors for scientists to wonder what organism is out there -- or could be created -- to accomplish the task.University of Michigan biological chemist Steve Ragsdale and colleagues have figured out a way to efficiently turn carbon dioxide into carbon monoxide using visible light, like sunlight.

• 06:00 CSHL-Mexican team coaxes sexually reproducing plant to brink of asexual reproduction

  Read the story at EurekAlert
  In a paper to appear online in Nature February 7, plant geneticists at Cold Spring Harbor Laboratory and the National Polytechnic Institute in Mexico report moving a step closer to the goal of turning plants that normally reproduce sexually into asexual reproducers, an outcome that would have profound implications for agriculture globally.

• 06:00 Gene site found for children's food allergy

  Read the story at EurekAlert
  Pediatrics researchers have identified the first major gene location responsible for a severe, often painful food allergy called eosinophilic esophagitis (EoE). In this disease, which may cause weight loss, vomiting, heartburn and swallowing difficulties, a patient may be unable to eat a wide variety of foods. A genome-wide association study found EoE was linked to a region of chromosome 5 that includes two genes.

  Read the story at EurekAlert
  New findings from a Université de Montréal and the Vaccine and Gene Therapy Institute of Florida study, in collaboration with scientists from the NIH and the McGill University Health Center, may soon lead to an expansion of the drug arsenal used to fight HIV. The Canada-US study is published today in the journal Nature Medicine.

• 06:00 Khirbet Qeiyafa identified as biblical 'Neta'im'

  Read the story at EurekAlert
  Has another mystery in the history of Israel been solved? Prof. Gershon Galil of the Department of Bible Studies at the University of Haifa has identified Khirbet Qeiyafa as "Neta'im", which is mentioned in the book of Chronicles. "The inhabitants of Neta'im were potters who worked in the king's service and inhabited an important administrative center near the border with the Philistines," explains Prof. Galil.

  Read the story at EurekAlert
  Scientists at the Stanford University School of Medicine have devised a software algorithm that could enable a common laboratory device to virtually separate a whole-blood sample into its different cell types and detect medically important gene-activity changes specific to any one of those cell types.

• 06:00 MIT researchers discover new way of producing electricity

  Read the story at EurekAlert
  A team of scientists at MIT have discovered a previously unknown phenomenon that can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes. The discovery could lead to a new way of producing electricity, the researchers say.

• 06:00 MIT scientists transform polyethylene into a heat-conducting material

  Read the story at EurekAlert
  Most polymers -- materials made of long, chain-like molecules -- are very good insulators for both heat and electricity. But an MIT team has found a way to transform the most widely used polymer, polyethylene, into a material that conducts heat just as well as most metals, yet remains an electrical insulator.

• 06:00 NIAID media availability: Food allergy-related disorder linked to master allergy gene

  Read the story at EurekAlert
  Scientists have identified a region of a human chromosome that is associated with eosinophilic esophagitis, a recently recognized allergic disease. People with EoE frequently have difficulty eating or may be allergic to one or more foods. This study further suggests that a suspected so-called master allergy gene may play a role in the development of this rare but debilitating disorder.

• 06:00 Vitamin D crucial to activating immune defenses

  Read the story at EurekAlert
  Scientists have found that vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin - the killer cells of the immune system -- T cells -- will not be able to react to and fight off serious infections in the body.The research team at the University of Copenhagen found that T cells first search for vitamin D in order to activate and if they cannot find enough of it will not complete the activation process.
