By this time, we can all conclude that Facebook is really ambitious when it comes to the production of high-end gadgets. This when you consider the Oculus line of devices, a VR wristband and RayBan AR glasses. And if that wasn’t enough, a new device is up for development.

The company has now revealed plans to build a mind-reading wristband letting people control devices without touching them. This is after the company finally acquired CTRL-Labs, a startup that is currently venturing into brain-computer interfaces. The deal has been reported to value at $1 billion.

The deal was then announced by Andrew Bosworth, Vice President of AR and VR at Facebook. “We spend a lot of time trying to get our technology to do what we want rather than enjoying the people around us,” he said.

Social media giant Facebook Inc. is planning to acquire CTRL-Labs, a technology startup that is working on a software to let people control a digital avatar using only with their thoughts. Apparently, as per reports, Facebook is ready to strike a deal between $500 million and $1 billion.

The closely held four-year-old startup, which has dozens of employees and has raised tens of millions in venture capital, uses a bracelet to measure neuron activity in a subject’s arm to determine movement that person is thinking about, even if they aren’t physically moving. That neuron activity is then translated into movement on a digital screen. However, Facebook has declined to comment on the price of the acquisition.

Technology like CTRL-Labs’s may sometime in the future play a crucial part of products like augmented reality glasses, where a user might want to control a computer without the need for buttons or a keyboard. “Your hands could be in your pocket, behind you,” explained Thomas Reardon, chief executive officer of CTRL-Labs, at an industry conference last December. “It’s the intention [to move], not the movement” itself that controls the avatar, he said.

Cells that become senescent irrevocably stop dividing under stress, spewing out a mix of inflammatory proteins that lead to chronic inflammation as more and more of the cells accumulate over time. Publishing in the September 24 edition of Cell Reports, researchers at the Buck Institute identified 44 specific senescence-associated proteins that are involved in blood clotting, marking the first time that cellular senescence has been associated with age-related blood clots.

“The incidence of venous thrombosis, which includes deep vein thrombosis and pulmonary embolism is extremely low until the age of 45, when it begins to rise rapidly. Over time it becomes a major risk factor for death. By 80, the condition affects five to six people per thousand individuals,” said Judith Campisi, PhD, Buck professor and senior co-author of the study. “Blood clots are also a serious side effect of chemotherapy, which sets off a cascade of senescence in those undergoing treatment. That’s why blood thinners, which carry their own risks, are often included in treatment protocols.”

Scientists in the Campisi lab and other labs around the world are working to develop senolytics, drugs which would clear senescent cells from the body, potentially providing treatment options for many age-related diseases that are either caused or linked to senescence. They include Alzheimer’s and Parkinson’s diseases, cardiovascular disease, osteoarthritis, macular degeneration, age-related cancers and sarcopenia, among others.

A nanoelectrode array that can simultaneously obtain intracellular recordings from thousands of connected mammalian neurons in vitro.

How our brain cells, or neurons, use electrical signals to communicate and coordinate for higher brain function is one of the biggest questions in all of science.

For decades, researchers have used electrodes to listen in on and record these signals. The patch clamp electrode, an electrode in a thin glass tube, revolutionized neurobiology in the 1970’s with its ability to penetrate a neuron and to record quiet but telltale signals from inside the cell. But this tool lacks the ability to record a ; it can measure only about 10 cells in parallel.

Now, researchers from Harvard University have developed an electronic that can perform high-sensitivity intracellular recording from thousands of connected simultaneously. This breakthrough allowed them to map synaptic connectivity at an unprecedented level, identifying hundreds of synaptic connections.

The human brain needs a continual supply of fuel. When this continual supply is interrupted brain cells begin to die. In the short-term, this can cause symptoms such as headaches, brain fog, & tiredness. Long-term exposure to environments that deplete sources of brain fuel from effectively getting into the cells leads to neurodegenerative diseases.

A new, non-invasive brain stimulation treatment shows promise in enhancing memories and cognitive function in those with Alzheimer’s disease. Transcranial electromagnetic treatment (TEMT) increases functional connectivity within the cingulate cortex. TEMT is also able to penetrate the brain to break up amyloid-beta and tau deposits, slowing the progression of Alzheimer’s disease.

The first population-level study on the link between gut bacteria and mental health identifies specific gut bacteria linked to depression and provides evidence that a wide range of gut bacteria can produce neuroactive compounds. Jeroen Raes (VIB-KU Leuven) and his team published these results today in the scientific journal Nature Microbiology.[br /][br /].

There has been a continuously increasing volume of data which has demonstrated that victimization, the clinical term for bullying, affects hundreds of millions of children and adolescents which can sometimes last for years and even decades. This is seen as a global health challenge by the World Health Organization and the United Nations. However, researchers maintain there is still a limited understanding of how this act can affect the developing brain physically.

Most of the research into the neurobiological processes that might contribute to these negative health outcomes has occurred in the past decade, much of it focused on bullying’s impact on the body’s stress response system. A paper published last December in the journal Molecular Psychiatry sheds some light on a different area: brain architecture. The trauma stemming from chronic bullying can affect the structure of the brain, according to longitudinal magnetic resonance imaging (MRI) data collected by an international team based at King’s College London. The findings echo previous research, which has demonstrated similar changes in children and adults who experienced what’s known as “child maltreatment” — neglect or abuse by adult caregivers.

Long-term changes to the brain’s structure and chemistry are an indicator “of how sinister bullying is” says Tracy Vaillancourt, a developmental psychologist at the University of Ottawa. Along with others in the field, she is hopeful that studies like the one from King’s College will be a catalyst for further research which could ultimately be used to inform policy decisions and support anti-bullying interventions.

In the ongoing efforts to control and treat Alzheimer’s, one of the more promising avenues of research is using electromagnetic waves to reverse memory loss – and a small study using this approach has reported some encouraging results.
