Unable to move a single muscle, even to open your eyes. Completely locked into your own body, yet fully conscious and aware.
Lou Gehrigโs diseaseโ amyotrophic lateral sclerosis (ALS)โis a nightmare in its advanced form, leaving patients without any means of communicating their needs and wishes.
Al Sandrock, former top scientist at Biogen, named CEO at Voyager Therapeutics
Al Sandrock, the top scientist at Biogen who exited last year in a dispute over its controversial Alzheimerโs treatment, has landed a new job as the CEO of Voyager Therapeutics, the company said Tuesday.
Voyagerโs appointment of Sandrock as its new CEO is the latest in a series of moves aimed at refocusing the company on a new gene therapy delivery technology, following setbacks with its earlier pipeline.
Scientists discover how molecule becomes anticancer weapon
Years of toil in the laboratory have revealed how a marine bacterium makes a potent anti-cancer molecule.
The anti-cancer molecule salinosporamide A, also called Marizomb, is in Phase III clinical trials to treat glioblastoma, a brain cancer. Scientists now for the first time understand the enzyme-driven process that activates the molecule.
Researchers at UC San Diegoโs Scripps Institution of Oceanography found that an enzyme called SalC assembles what the team calls the salinosporamide anti-cancer โwarhead.โ Scripps graduate student Katherine Bauman is the lead author of a paper that explains the assembly process in the March 21 issue of Nature Chemical Biology.
Looking at a Human Face Triggers Activity in Our Brains Unlike Any Other Object
It may not feel like it, but our eyes are constantly making rapid, tiny movements called saccades, taking in new information as we focus our gaze on various things in the world. As we do so, our brains receive the input โ and depending on what the object of our gaze is, it turns out the brain activity triggered can be quite unique.
โWhile we typically do not perceive our own eye movements, the abrupt change in visual input with each saccade has substantial consequences at the neuronal level,โ researchers explain in a new study led by first author and cognitive neuroscientist Tobias Staudigl from Ludwig Maximilian University of Munich in Germany.
In an experiment, Staudigl and fellow researchers worked with 13 epilepsy patients, who had electrodes implanted in their brains to monitor their condition. This kind of intervention can be helpful for brain scientists, so they often turn to such patients with electrodes already implanted, in case theyโd be willing to volunteer their time.
Metaโs Yann LeCun strives for human-level AI
What is the next step toward bridging the gap between natural and artificial intelligence? Scientists and researchers are divided on the answer. Yann LeCun, Chief AI Scientist at Meta and the recipient of the 2018 Turing Award, is betting on self-supervised learning, machine learning models that can be trained without the need for human-labeled examples.
LeCun has been thinking and talking about self-supervised and unsupervised learning for years. But as his research and the fields of AI and neuroscience have progressed, his vision has converged around several promising concepts and trends.
In a recent event held by Meta AI, LeCun discussed possible paths toward human-level AI, challenges that remain and the impact of advances in AI.
Mutation protecting against Alzheimerโs edited into human cells
Treating brain diseases is also always difficult because of something called the โblood-brain barrier.โ This wall of cells is designed to prevent toxins and pathogens from getting from the blood into the brain โ but it also makes it hard to get treatments into the brain.
People with the Icelandic mutation are five times more likely to reach their 85 birthday without an Alzheimerโs diagnosis.
The Icelandic variant: Scientists have identified a couple of differences between the brains of people with Alzheimerโs and those of healthy people.
Assume that animals have feelings too, say cognitive biologists
We should assume that animals can have feelings too. From an ethical point of view this should inform our dealings with animals, researchers from Leiden University and Utrecht University argue in an opinion article that was published in the scientific journal Affective Science on Thursday 10 March.
Some of the leading behavioral scientists in the world have hypothesized that many animal species can have emotions. But whether animals also have feelings is the subject of much debate, and some behavioral scientists believe they do not. This is incorrect, say cognitive psychologist Mariska Kret (Leiden University) and behavioral biologists Jorg Massen (Utrecht University) and Frans de Waal (Emory University and endowed professor in Utrecht). Based on observations, there is a good chance that animals can also have feelings; it is just very difficult to investigate this.
Bacteria in the Nose Can Sneak Into the Brain โ May Increase Risk of Alzheimerโs Disease
New research from Griffith University has shown that a bacterium commonly present in the nose can sneak into the brain and set off a cascade of events that may lead to Alzheimerโs disease.
Associate Professor Jenny Ekberg and colleagues from the Clem Jones Centre for Neurobiology and Stem Cell Research at Menzies Health Institute Queensland and Griffith Institute for Drug Discovery, in collaboration with Queensland University of Technology, have discovered that the bacterium Chlamydia pneumoniae can invade the brain via the nerves of the nasal cavity.
