Noninvasive brain computer interface could turn thoughts into motion

"Brain cap" technology being developed at the University of Maryland allows users to turn their thoughts into motion. Associate Professor of Kinesiology José 'Pepe' L. Contreras-Vidal and his team have created a non-invasive, sensor-lined cap with neural interface software that soon could be used to control computers, robotic prosthetic limbs, motorized wheelchairs and even digital avatars.

Deciding what to eat can be influenced by shifting attention towards healthy side of life

You're trying to decide what to eat for dinner. Should it be the chicken and broccoli? The super-sized fast-food burger? Skip it entirely and just get some Rocky Road?

IRCM geneticists discover an unsuspected organization of pituitary cells

A team of geneticists at the Institut de recherches cliniques de Montr-al (IRCM), directed by Dr. Jacques Drouin, made an unexpected discovery on hormone secretion. Contrary to common belief, the researchers found that pituitary cells are organized in structured networks. The scientific breakthrough was published yesterday by the scientific journal Proceedings of the National Academy of Sciences.

Dilemma of single vs. double embryo transfers

Elsevier announced the publication of several commentaries in the scientific journal Reproductive BioMedicine Online on the subject of how many embryos it is safe and proper to place in a uterus, and how best to regulate this decision. It is a dilemma faced by all patients anxiously caught between no pregnancies at all or facing the prospect of twins or triplets. In this difficult place it is often all too easy to think that the latter option must be the best. But is it?

Invadopodia could help survival of cancer cells

Delicate, threadlike protrusions used by cancer cells when they invade other tissues in the body could also help them escape control mechanisms supposed to eliminate them, a research group led by led by Bradley Davidson in the University of Arizona's department of molecular and cellular biology reports in Nature Cell Biology.

Insect virus holds key to safer stem cell therapy: Singapore scientists

The future of regenerative medicine lies in harnessing the potential of the human body to renew and repair itself. Now, scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have developed a new genetic engineering technique that promises safer stem cell therapy for cancer patients. Using an insect virus, the team of researchers successfully inserted a therapeutic gene into a safe site in the DNA of human embryonic stem cells without compromising the functionality of the engineered cells.

U.S. Judge approves federal funding for embryonic research

Federal funding of human embryonic stem cell (hESC) research is now legal in the United States. Chief judge of the US District Court for the District of Columbia Royce Lamberth has ruled on the case Sherley et al. v. Sebelius, in favor of hESC research. This overturns an existing law that prohibits the government from funding research that destroys the embryo.

Carcinogenesis is just another form of speciation, proposes new theory

Cancer patients may view their tumors as parasites taking over their bodies, but this is more than a metaphor for Peter Duesberg, a molecular and cell biology professor at the University of California, Berkeley.

Scientists reveal complete three-dimensional atomic structure of an activated GPCR

G protein-coupled receptors (GPCRs) are popular drug targets, accounting for about one-third of approved drugs and many hundreds of drugs currently in development. They act as molecular switches that transduce extracellular signals by activating heterotrimeric G proteins located at the inside of the cell.

Study reveals several compounds that block cancer cell invasion

Metastasis-the spread of cancer from the place where it first started to another place in the body-is the most common reason that cancer treatments fail. To metastasize, some types of cancer cells rely on invadopodia, cellular membrane projections that act like feet, helping them "walk" away from the primary tumor and invade surrounding tissues.

Positive results from phase Ib/IIa trial of novel molecular technique for Duchenne muscular dystrophy

A molecular technique originally developed at the University of North Carolina at Chapel Hill has taken one step closer to becoming a treatment for the devastating genetic disease Duchenne muscular dystrophy.

All football players do not get chronic traumatic encephalopathy

Preliminary results from the first four brains donated to the Canadian Sports Concussion Project at the Krembil Neuroscience Centre, TorontoWesternHospital, reveal that two of the four former Canadian Football League (CFL) players suffered from a brain disease known as Chronic Traumatic Encephalopathy (CTE), while two did not show signs of CTE.

New silicone chip could make genetic analysis far more sensitive, rapid, and cost-effective

UBC researchers have invented a silicone chip that could make genetic analysis far more sensitive, rapid, and cost-effective by allowing individual cells to fall into place like balls in a pinball machine.

Study suggests common process for both pleasurable and anxiety-reducing effects of nicotine

Removing a protein from cells located in the brain's reward center blocks the anxiety-reducing and rewarding effects of nicotine, according to a new animal study in the July 27 issue of The Journal of Neuroscience. The findings may help researchers better understand how nicotine affects the brain.

Nano-emulsion shows promise for Viagra patch

Sildenafil citrate, commonly known as Viagra, is currently the first choice drug for erectile dysfunction but despite its success oral delivery of the drug is hampered by numerous side effects, the long delay before it starts working and the short amount of time it lasts. Researchers in Egypt think they may have a solution via nanotechnology.
