Immune cell discovery could help to halt cancer spread
Melbourne researchers have revealed the critical importance of highly specialized immune cells, called natural killer cells, in killing melanoma cells that have spread to the lungs. These natural killer cells could be harnessed to hunt down and kill cancers that have spread in the body. The team, from the Walter and Eliza Hall Institute, also found natural killer cells were critical to the body's rejection of donor bone marrow transplants and in the runaway immune response during toxic shock syndrome.

Protein found to block benefits of vitamin A cancer therapy
Retinoic acid is a form of vitamin A that is used to treat and help prevent the recurrence of a variety of cancers, but for some patients the drug is not effective. The reason for this resistance was unclear until this week when researchers from Virginia Commonwealth University Massey Cancer Center demonstrated that a protein known as AEG-1 blocks the effects of retinoic acid in leukemia and liver cancer.

Message to parents: Babies don't 'start from scratch'
There's now overwhelming evidence that a child's future health is influenced by more than just their parents' genetic material, and that children born of unhealthy parents will already be pre-programmed for greater risk of poor health, according to University of Adelaide researchers.

Prevalence, risk factors for diabetic macular edema explored in study
The odds of having diabetic macular edema, a leading cause of vision loss in patients with diabetes mellitus, appears to be higher in non-Hispanic black patients than white patients, as well as in those individuals who have had diabetes longer and have higher levels of hemoglobin A1c.

Harnessing the power of bacteria's sophisticated immune system
Bacteria's ability to destroy viruses has long puzzled scientists, but researchers at the Johns Hopkins Bloomberg School of Public Health say they now have a clear picture of the bacterial immune system and say its unique shape is likely why bacteria can so quickly recognize and destroy their assailants.

Mass layoffs linked to increased teen suicide attempts
Mass layoffs trigger increased suicide attempts and other suicide-related behaviors among some teenagers, especially black teens, says new research from Duke University. When 1 percent of a state's working population lost jobs, suicide-related behaviors increased by 2 to 3 percent among girls and black adolescents in the following year. Among girls, thoughts of suicide and suicide plans rose. Among black teens, thoughts of suicide, suicide plans and suicide attempts all increased.

Memories of errors foster faster learning
Using a deceptively simple set of experiments, researchers at Johns Hopkins have learned why people learn an identical or similar task faster the second, third and subsequent time around. The reason: they are aided not only by memories of how to perform the task, but also by memories of the errors made the first time.

Long antibiotic treatments: Slowly growing bacteria to blame
Whether pneumonia or sepsis -- infectious diseases are becoming increasingly difficult to treat. One reason for this is the growing antibiotic resistance. But even non-resistant bacteria can survive antibiotics for some time, and that's why treatments need to be continued for several days or weeks. Scientists at the Biozentrum of the University of Basel showed that bacteria with vastly different antibiotic sensitivity coexist within the same tissue. In the scientific journal Cell they report that, in particular, slowly growing pathogens hamper treatment.

Bypass commands from the brain to legs through a computer
A Japanese research group led by Shusaku Sasada, research fellow and Yukio Nishimura, associate professor of the National Institute for Physiological Sciences and National Institutes of Natural Sciences, has successfully made an artificial connection from the brain to the locomotion center in the spinal cord by bypassing with a computer and exercised control over walking. This result is published in The Journal of Neuroscience.

Scientists use lasers to control mouse brain switchboard
Using mice and flashes of light, scientists show that just a few nerve cells in the brain may control the switch between internal thoughts and external distractions. The study may be a breakthrough in understanding how a critical part of the brain, called the thalamic reticular nucleus, influences consciousness.

NSAIDs benefit overweight breast cancer patients, study finds
Researchers have determined that postmenopausal overweight or obese breast cancer patients receiving hormone therapy as part of their treatment and who use nonsteroidal anti-inflammatory drugs such as aspirin or ibuprofen have significantly lower breast cancer recurrence rates and a sizable delay in time to cancer recurrence.

Fukushima's legacy
Scientists began gathering biological information only a few months after the disastrous 2011 meltdown of the Fukushima power plant in Japan. Results of these studies are now beginning to reveal serious biological effects of the Fukushima radiation on non-human organisms ranging from plants to butterflies to birds. A series of articles summarizing these studies has been published in the Journal of Heredity describing impacts ranging from population declines to genetic damage.

Mayo Clinic challenges some recommendations in updated cholesterol treatment guideline
A Mayo Clinic task force challenges some recommendations in the updated guideline for cholesterol treatment unveiled by the American College of Cardiology and American Heart Association in 2013. The task force concludes, based on current evidence, that not all patients encouraged to take cholesterol-lowering medications, such as statins, may benefit from them and that the guideline missed some important conditions that might benefit from medication.

Aspirin may slow recurrence in breast cancer patients
New findings published in the journal Cancer Research reveal some postmenopausal overweight breast cancer patients who use anti-inflammatory drugs like aspirin or ibuprofen have significantly lower breast cancer recurrence rates. Anti-inflammatory use reduced the recurrence of ERα positive breast cancer by 50 percent and extended patients' disease-free period by more than two years. Research was performed at the Cancer Therapy & Research Center at the University of Texas Health Science Center San Antonio and University of Texas Austin.

Researchers identify a brain 'switchboard' important in attention and sleep
Researchers at NYU Langone Medical Center and elsewhere, using a mouse model, have recorded the activity of individual nerve cells in a small part of the brain that works as a 'switchboard,' directing signals coming from the outside world or internal memories. Because human brain disorders such as schizophrenia, autism, and post-traumatic stress disorder typically show disturbances in that switchboard, the investigators say the work suggests new strategies in understanding and treating them.

Drugs that flush out HIV may impair killer T cells, possibly hindering HIV eradication
Histone deacetylase (HDAC) inhibitors have shown promise in 'flushing out' HIV from latently infected cells, potentially exposing the reservoirs available for elimination by cytotoxic T lymphocytes (CTL), also called killer T cells. However, findings published on Aug. 14 in PLOS Pathogens now suggest that treatment with HDAC inhibitors might suppress CTL activity and therefore compromise the 'kill' part of a two-pronged 'flush-and-kill' HIV eradication strategy.
