Brain power: Wirelessly supplying power to the brain

by Dr. Jekyll in Lunatic Laboratories

Human and animal movements generate slight neural signals from their brain cells. These signals obtained using a neural interface are essential for realizing brain-machine interfaces (BMI). Such neural recording systems using wires to connect the implanted device to an external device can cause infections through the opening in the skull. One method of solving this issue is to develop a wireless neural interface that is fully implantable on the brain.

We can build it better: Synthetic biopathway turns agriculture waste into ‘green’ products

by Dr. Jekyll in Lunatic Laboratories

Researchers at the University of Minnesota have engineered a new synthetic biopathway that can more efficiently and cost-effectively turn agricultural waste, like corn stover and orange peels, into a variety of useful products ranging from spandex to chicken feed.

Why Ask for Directions? (A Guest Post)

by Miss Behavior in The Scorpion and the Frog

by Anna Schneider For the iconic monarch butterfly, the shorter days in fall mean it’s time to pack up and head south to a warmer climate! Just like clockwork, the Eastern population of monarch butterflies makes a 2000 mile journey to their winter paradise roosts in central Mexico. The journey in itself is one of the greatest migrations among all animals. But here’s the catch: none of these butterflies has made this trip before. Several generations of monarchs have come and gon........ Read more »

The molecular link between psychiatric disorders and type 2 diabetes

by Dr. Jekyll in Lunatic Laboratories

There may be a genetic connection between some mental health disorders and type 2 diabetes. In a new report, scientists show that a gene called “DISC1,” which is believed to play a role in mental health disorders, such as schizophrenia, bipolar disorder and some forms of depression, influences the function of pancreatic beta cells which produce insulin to maintain normal blood glucose levels.

Brain plasticity assorted into functional networks

by Dr. Jekyll in Lunatic Laboratories

Plasticity of the brain, what does that even mean? Well the good news is that it isn’t just a marketing ploy, the brain needs to be “plastic” because we need to be able to adapt. Frankly speaking, the brain still has a lot to learn about itself. Scientists at the Virginia Tech Carilion Research Institute have made a key finding of the striking differences in how the brain’s cells can change through experience.

Do songbirds perceive melody different from humans?

by Henkjan Honing in Music Matters

Last week a fascinating study appeared in PNAS on melody cognition in sparrows (Sturnus vulgaris). It provides an alternative interpretation to the widespread believe that songbirds have a strong bias to rely on absolute pitch (AP) for the recognition of melodies (e.g. Hulse et al., 1992)....

Man-made underwater sound may have wider ecosystem effects

by Dr. Jekyll in Lunatic Laboratories

Underwater sound linked to human activity could alter the behaviour of seabed creatures that play a vital role in marine ecosystems, according to new research from the University of Southampton. The study found that exposure to sounds that resemble shipping traffic and offshore construction activities results in behavioural responses in certain invertebrate species that live in the marine sediment.

Investigating potential fetal exposure to antidepressants

by Dr. Jekyll in Lunatic Laboratories

Depression is a serious issue for expecting mothers. Left untreated, depression could have implications for a fetus’s health. But treating the disease during pregnancy may carry health risks for the developing fetus, which makes an expecting mother’s decision whether to take medication a very difficult one. To better understand how antidepressants affect fetuses during pregnancy, scientists studied exposure in mice.

Depressed or inflamed? Inflammation attacks brain’s reward center

by Dr. Jekyll in Lunatic Laboratories

Inflammation is a good thing, it helps the body fight disease, and without it we wouldn't survive. Unfortunately, when inflammation isn't kept under control it can wreak havoc on the body. From potentially causing alzheimer's to arthritis it seems that unchecked inflammation can cause all sorts of issues. In fact, a new study adds to the list of issues out of control inflammation causes in the body.

Are ‘predatory’ journals completely negative, or also a sign of something positive?

by SciELO in SciELO in Perspective

Something that is generally, and justifiably, considered negative, can, however, also be a harbinger of an underlying positive development. The case in point is the existence of so-called ‘predatory’ journals, which have – inevitably – emerged in an environment in which a true market for scientific publishing services is slowly taking shape. … Read More →...

Blood pressure medicine may improve conversational skills of individuals with autism

by Dr. Jekyll in Lunatic Laboratories

An estimated 1 in 68 children in the United States has autism. The neurodevelopmental disorder, which impairs communication and social interaction skills, can be treated with medications and behavioral therapies, though there is no cure. Now, University of Missouri researchers have found that a medication commonly used to treat high blood pressure and irregular heartbeats may have the potential to improve some social functions of individuals with autism.

The brains of patients with schizophrenia vary depending on the type of schizophrenia

by Dr. Jekyll in Lunatic Laboratories

I have a friend who lost an eye to his brother. Yes, you read that correctly, his brother tried to kill him and in the process he lost his eye. I’ve told this story before, but whenever new schizophrenia research comes out I feel the need to tell it again. While he has forgiven his brother (partly because not long after, he was diagnosed as schizophrenic), he will not be able to see him again until he is released from prison. A tragedy that could’ve been avoided had he been diagnosed sooner......... Read more »

Neurological adaptations to the presence of toxic HIV protein

by Dr. Jekyll in Lunatic Laboratories

Nearly half of HIV infected patients suffer from impaired neurocognitive function. The HIV protein transactivator of transcription (Tat) is an important contributor to HIV neuropathogenesis because it is a potent neurotoxin that continues to be produced despite treatment with antiretroviral therapy.

How to unlock inaccessible genes

by Dr. Jekyll in Lunatic Laboratories

An international team of biologists has discovered how specialized enzymes remodel the extremely condensed genetic material in the nucleus of cells in order to control which genes can be used. It was known that the DNA in cells is wrapped around proteins in structures called nucleosomes that resemble beads on a string, which allow the genetic material to be folded and compacted into a structure called chromatin.

It’s complicated: Benefits and toxicity of anti-prion antibodies in the brain

by Dr. Jekyll in Lunatic Laboratories

Immunotherapy to ameliorate neurodegeneration by targeting brain protein aggregates with antibodies is an area of intense investigation. A new study examines seemingly contradictory earlier results of targeting the prion protein and proposes a cautionary way forward to further test related therapeutic approaches.

Why you should never use the term ‘the mentally ill’

by Dr. Jekyll in Lunatic Laboratories

Even subtle differences in how you refer to people with mental illness can affect levels of tolerance, a new study has found. In a first-of-its-kind study, researchers found that participants showed less tolerance toward people who were referred to as "the mentally ill" when compared to those referred to as "people with mental illness."

60 genetic disorders affect skin and nervous system

by Dr. Jekyll in Lunatic Laboratories

One of the most common genetic disorders is a condition called neurofibromatosis, which causes brown spots on the skin and benign tumors on the brain, spinal cord and other parts of the nervous system. Neurofibromatosis is one of at least 60 genetic diseases called neurocutaneous disorders that involve the skin, central nervous system, and/or peripheral nervous system.
