The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Protein, not sugar, stimulates cells keeping us thin and awake

A new study has found that protein and not sugar activates the cells responsible for keeping us awake and burning calories. The research, published in the 17 November issue of the scientific journal Neuron, has implications for understanding obesity and sleep disorders.

Researchers discover a factor in synapse-building and pruning

Like a gardener who stakes some plants and weeds out others, the brain is constantly building networks of synapses, while pruning out redundant or unneeded synapses. Researchers at The Jackson Laboratory led by Assistant Professor Zhong-wei Zhang, Ph.D., have discovered a factor in synapse-building, also showing that the building and pruning processes occur independent of each other.

Aurora kinase inhibitor may treat neuroendocrine prostate cancer

An international team of researchers led by clinicians at Weill Cornell Medical College have discovered a genetic Achilles' heel in an aggressive type of prostate cancer -- a vulnerability they say can be attacked by a targeted drug that is already in clinical trials to treat other types of cancers.

Cancer cells tap into natural recycling system to obtain energy

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered that cancer cells tap into a natural recycling system to obtain the energy they need to keep dividing. In a study with potential implications for cancer treatments, Einstein researchers used genetic manipulation to turn off this recycling system within the walls of cells and stop both tumor growth and metastasis.

New 2-DG-ABT combination cancer therapy triggers apoptosis

Researchers at the University of California, San Diego School of Medicine and Kyushu University Medical School say a novel combination of a specific sugar molecule with a pair of cell-killing drugs prompts a wide variety of cancer cell types to kill themselves, a process called apoptosis or programmed cell death.

People with prior stroke or diabetes benefit from thrombolytic therapy

People with a history of stroke or diabetes who were given clot-busting drugs to break up blood clots after stroke fared better than those who did not receive the drugs, according to a study published in the November 16, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology.

Link between NRXN3 gene and impulsivity

Being impulsive can lead us to say things we regret, buy things we really don't need, engage in behaviors that are risky and even develop troublesome addictions. But are different kinds of hastiness and rashness embedded in our DNA? A new study suggests the answer is yes -- especially if you're a man.

Dipyrone may reduce brain damage after stroke

An older nonsteroidal anti-inflammatory drug (NSAID) called dipyrone may offer a new approach to reducing injury to brain tissue after a stroke, according to a study in the October issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Conventional approach could soon increase recurrent stroke risk after first event

For patients who have suffered an ischemic stroke, traditional treatment prescribes keeping subsequent blood pressure levels as low as possible to reduce the risk of another stroke. A new international study, however, suggests this conventional approach may not be helpful, and could actually increase recurrent stroke risk - at least in the first few months after the first event.
