Early fire use ignites discussion about the evolution of human brainpower
New evidence that early modern humans used fire in southern Africa in a controlled way to increase the quality and efficiency of stone tools is changing how researchers understand the evolution of human behavior, and in particular, the evolution of human brain power. view more (2009-08-14)
Human mind: Sound and vision wired through same 'black box'
Sounds and images share a similar neural code in the human brain, according to a new Canadian study. view more (2009-08-13)
A Window into the Brain
When we absorb new information, the human brain reshapes itself to store this newfound knowledge. But where exactly is the new knowledge kept, and how does that capacity to adapt reflect our risk for Alzheimer's disease and other forms of senile dementia later in our lives? view more (2009-08-13)
Formal education lessens the impact of Alzheimer's disease
Researchers at the Department of Psychiatry, Klinikum rechts der Isar, Technische Universität München, investigated the effects of formal education on the symptoms of Alzheimer's disease. view more (2009-08-12)
Sequential TACE and cryosurgery can improve survival times for patients with HCC?
Hepatocellular carcinoma (HCC)--a liver cancer--is recognized as one of the most common cancers in the world that disproportionately affects Southeast Asians and Africans. view more (2009-08-12)
New Discovery Brings Hope to Treatment of Lymphatic Diseases
Researchers in the laboratory of Dr. Jayakrishna Ambati at the University of Kentucky have discovered the first naturally occurring molecule that selectively blocks lymphatic vessel growth. view more (2009-08-11)
Life and death in the living brain
Like clockwork, brain regions in many songbird species expand and shrink seasonally in response to hormones. Now, for the first time, University of Washington neurobiologists have interrupted this natural "annual remodeling" of the brain and have shown that there is a direct link between the death of old neurons and their replacement by... view more...

New light-emitting biomaterial could improve tumor imaging, study shows
A new material developed at the University of Virginia - an oxygen nanosensor that couples a light-emitting dye with a biopolymer - simplifies the imaging of oxygen-deficient regions of tumors. view more (2009-08-11)
Einstein researchers identify potential target for metastatic cancer
The deadliest part of the cancer process, metastasis, appears to rely on help from macrophages, potent immune system cells that usually defend vigorously against disease, researchers at Albert Einstein College of Medicine of Yeshiva University report. view more (2009-08-11)
Traffic jam in brain causes schizophrenia symptoms
Schizophrenia waits silently until a seemingly normal child becomes a teenager or young adult. Then it swoops down and derails a young life. view more (2009-08-11)
Researchers find alcoholics display abnormal brain activity when processing facial expressions
Researchers from Boston University School of Medicine (BUSM) have found that individuals who have a long history of alcoholism, but who have been abstinent for at least a month up to many years, showed abnormal brain activity when looking at facial expressions of others. view more (2009-08-11)
New groundbreaking treatment for oxygen-deprived newborns
Until now immediate cooling of the newborn infant was the only treatment that could possibly prevent brain damage following oxygen deprivation during delivery. view more (2009-08-11)
Tumor suppressor pulls double shift as reprogramming watchdog
A collaborative study by researchers at the Salk Institute for Biological Studies uncovered that the tumor suppressor p53, which made its name as "guardian of the genome", not only stops cells that could become cancerous in their tracks but also controls somatic cell reprogramming. view more (2009-08-10)
Unlikely genetic suspect implicated in common brain defect
A genetic search that wound its way from patients to mouse models and back to patients has uncovered an unlikely gene critically involved in a common birth defect which causes mental retardation, motor delays and sometimes autism, providing a new mechanism and potentially improving treatment for the disorder. view more (2009-08-10)
Chinese acupuncture affects brain's ability to regulate pain, UM study shows
Acupuncture has been used in East-Asian medicine for thousands of years to treat pain, possibly by activating the body's natural painkillers. But how it works at the cellular level is largely unknown. view more (2009-08-10)
Estrogen-Dependent Switch Tempers Killing Activity of Immune Cells
The sex hormone estrogen tempers the killing activity of a specific group of immune cells, the cytotoxic T cells (CTLs), which are known to attack tumor cells and cells infected by viruses. view more (2009-08-10)
STAT3 Gene Regulates Cancer Stem Cells in Brain Cancer
In a study published online in advance of print in Stem Cells, Tufts researchers report that the STAT3 gene regulates cancer stem cells in brain cancer. Cancer stem cells have many characteristics of stem cells and are thought to be the cells that drive tumor formation. view more (2009-08-10)
Tumor mutations can predict chemo success
New work by MIT cancer biologists shows that the interplay between two key genes that are often defective in tumors determines how cancer cells respond to chemotherapy. view more (2009-08-07)
Sensitizing tumor response to cancer therapy
Two forms of skin and brain cancer respond very poorly to chemotherapy and radiation: melanoma and glioblastoma multiforme brain cancer. view more (2009-08-06)
Pitt researchers find promising candidate protein for cancer prevention vaccines
Researchers at the University of Pittsburgh School of Medicine have learned that some healthy people naturally developed an immune response against a protein that is made in excess levels in many cancers, including breast, lung, and head and neck cancers. view more (2009-08-05)
