Tennessee Gov. declares February as 'St. Jude Month'

In 1962, St. Jude Children's Research Hospital opened its doors amid an emotionally charged debate regarding how to treat childhood cancer. At that time, few children with the most common form of childhood cancer survived, and many physicians believed treatment was futile. St. Jude physicians and researchers took a radically different approach, and these efforts proved pivotal in changing the way the world treats childhood cancer.

Two different research groups make similar advances in AD study

Two different research groups have independently made the same important discoveries on how Alzheimer's disease spreads in the brain, according to a February 2 New York Times story. The groups' findings have the potential to give us a much more sophisticated understanding of what goes wrong in Alzheimer's disease and, more importantly, what can be done to prevent or repair damage in the brain.

Future of social robotics requires meeting the expectations of human brain

After years of existing only in fiction, social robots are finally being designed that can more closely emulate how people express themselves, interact and learn - and doing so while performing jobs like teaching social behavior to children with autism or helping stroke patients with their physical rehabilitation exercises.

Study offers evidence that toxic forms of Alzheimer's protein spread in the brain

Tau tangles are one half of the twin hallmark pathologies of Alzheimer's disease—the half that is most closely tied to the death of neurons. A study in the February 1 PLoS One offers evidence that the toxic forms of tau that cause these tangles spread throughout the brain by moving from one neuron to the next in a pattern that tracks anatomical synaptic connections of the earliest-hit nerve cells in the brain.

New approach can solve treatment-resistant problem in cancers

Free-flowing cancer cells have been mapped with unprecedented accuracy in the bloodstream of patients with prostate, breast and pancreatic cancer, using a brand new approach, in an attempt to assess and control the disease as it spreads in real time through the body, and solve the problem of predicting response and resistance to therapies.

Scientists discover extremely long-lived proteins in aging rats

One of the big mysteries in biology is why cells age. Now scientists at the Salk Institute for Biological Studies report that they have discovered a weakness in a component of brain cells that may explain how the aging process occurs in the brain.

G-CSF's AX200 does not improve stroke-related disability

A new drug that showed promise in animal studies and an early clinical trial didn't improve disability among stroke patients, according to late-breaking research presented at the American Stroke Association's International Stroke Conference 2012.

Soy isoflavone supplements do not reduce breast cancer cell proliferation

Soy isoflavone supplements did not decrease breast cancer cell proliferation in a randomized clinical trial, according to a study published in Cancer Prevention Research, a journal of the American Association for Cancer Research.

Whole-exome sequencing discovers cause of glycosylation disorders

Sequencing a patient's entire genome to discover the source of his or her disease is not routine - yet. But geneticists are getting close. A case report, published this week in the American Journal of Human Genetics, shows how researchers can combine a simple blood test with an "executive summary" scan of the genome to diagnose a type of severe metabolic disease.

UCSD Moores Cancer Center offers NovoTTF procedure for patients with GBM

Jim Black is fighting the meanest, most aggressive, most common kind of brain tumor in the United States: recurrent glioblastoma multiforme (GBM). In the United States, each year, approximately 10,000 patients are affected by GBM. Now, a novel investigational device - available only at clinical trial sites - is offering new hope to these patients.

Exelixis reports preliminary data from cabozantinib phase 1b trial on RCC

Exelixis, Inc. today reported preliminary data from a cohort of heavily pretreated patients with metastatic refractory renal cell carcinoma (RCC) participating in an ongoing phase 1b trial of cabozantinib.

New MRSA ‘superbug’ worries experts

A deadly mutant bug could be spreading among the public warn experts. The deadly strain of Methicillin-Resistant Staphylococcus Aureus (MRSA) called USA300 passes easily through skin-to-skin contact. It can also survive on surfaces and so has the potential to be picked up on crowded buses and tubes. The first cases were seen in the US but cases are now being reported in the community and not just hospitals in Britain.

Change in sickle cell anemia prevention strategies decreases racial disparities in stroke-related deaths

The disparity in stroke-related deaths among black and white children dramatically narrowed after prevention strategies changed to include ultrasound screening and chronic blood transfusions for children with sickle cell anemia, according to research presented at the American Stroke Association's International Stroke Conference 2012.

Scientists identify molecular switch that controls ATF2's dual functions

The National Cancer Institute (NCI) estimates that as many as one in 51 men and women will be diagnosed with melanoma-the deadliest form of skin cancer-at some point during their lifetimes. A research team led by Ze'ev Ronai, Ph.D. at Sanford-Burnham Medical Research Institute (Sanford-Burnham) is working to unravel the molecular mechanisms underlying the development and progression of this disease in hopes of improving prevention and treatment strategies

Small molecules at cell's membrane enable cell movement

Cell biologists at Johns Hopkins have identified key steps in how certain molecules alter a cell's skeletal shape and drive the cell's movement.

Molecular subtypes of lung cancer manifest as different diseases

Different kinds of lung cancer behave in different ways, suggesting they are fundamentally different diseases. According to a University of Colorado Cancer Center study published in Cancer, the official journal of the American Cancer Society, different subgroups of non-small cell lung cancer (NSCLC) show distinct patterns of spread in the body.

New procedure rapidly induces nerve regeneration

American scientists believe a new procedure to repair severed nerves could result in patients recovering in days or weeks, rather than months or years. The team used a cellular mechanism similar to that used by many invertebrates to repair damage to nerve axons. Their results are published today in the Journal of Neuroscience Research.

International conference focuses on where and how memory is formed

The University of Haifa is hosting an international conference of leading brain researchers from around the world next week, where the participants will be attempting to answer the question of where and how memory is stored; or in less ordinary terms: "Cell and molecular mechanisms of memory formation".

Immune cells from healthy individuals effectively kill cancer cells

Immune cells from healthy individuals can be the new immune cure for cancer. This treatment can kill cancer cells without destroying neighbouring cells. The hope is to eradicate cancer for ever.

Scientists uncover genes that govern male and female behaviors

Hormones shape our bodies, make us fertile, excite our most basic urges, and as scientists have known for years, they govern the behaviors that separate men from women. But how? Now a team of scientists at the University of California, San Francisco (UCSF) has uncovered many genes influenced by the male and female sex hormones testosterone and estrogen that, in turn, govern several specific types of male and female behaviors in mice.
