Scientists control rat’s movements with their minds

The concept of mind control sounds like something that only exists in sci-fi movies. Until now. Recent work from Zhejiang University on developing a system appears to allow human mind control over the rat’s movements. This “brain-to-brain interface”, or BBI, is achieved by wirelessly coupling the brains of a human operator and a “rat cyborg” and transmitting brain activity in real time. Brain cells communicate … Continue reading Scientists control rat’s movements with their minds

Efficient drug delivery platform into the brain

Treatment of neurological disorders, such as Parkinson’s disease and stroke, has always been a challenging task, partly due to the existence of the blood-brain barrier (BBB). The BBB is a border that separates the blood circulation from the surrounding brain tissue. In a healthy brain, the BBB only allows the passage of nutrients crucial to brain function, while restricting the transportation of other substances, including … Continue reading Efficient drug delivery platform into the brain

Nanowires

  Nanowires are thin structures measuring 0.000000001 meters in diameter, which is so thin that they essentially behave as if they only have one-dimension. This one-dimensional nature gives nanowires a ton of interesting electrical and magnetic properties, which are super useful in electronics and medical devices, especially as they are getting smaller and smaller. Nanowires can be made from a number of different materials. The grey columns in this … Continue reading Nanowires

Nano-antidote provides long-term protection against nerve agents

Nerve agents are toxic chemicals that disrupt signals in the nervous system. They can be absorbed easily through skin contact or by breathing. Exposure to nerve agents interferes with nerve cell signaling and prevents muscles from relaxing, quickly leading to muscle paralysis and eventually death by asphyxiation or cardiac arrest. Treatment is possible but must be administered within minutes of exposure. No long-term vaccine or … Continue reading Nano-antidote provides long-term protection against nerve agents

A Joint Effort: Inheritance of Mitochondrial DNA from Both Parents

Researchers at Cincinnati Children’s Hospital Medical Center have found evidence in three families for inheritance of mitochondrial DNA from both mothers and fathers, in contrast to the conventional belief that this genetic transmission is exclusively maternal. This discovery opens new doorways in molecular biology and genetics to understand this inheritance pattern, and properly harnessing the process could dramatically reduce chances of inheriting mitochondrial disorders. Continue reading A Joint Effort: Inheritance of Mitochondrial DNA from Both Parents

Treating knee osteoarthritis with a nanoparticle injection

Osteoarthritis is a joint disease that occurs when the cartilage (the flexible and slippery tissue that protects the ends of bones in the joints) wears away, causing bones to rub against each other. Common causes of osteoarthritis include aging, sports injuries, and excess body weight. Scientists from Tsinghua University and Shanghai Jiao Tong University have developed nanoparticles that can be injected as lubricant into the … Continue reading Treating knee osteoarthritis with a nanoparticle injection

China’s Genetically Edited babies: What really happened?

A Chinese researcher, He Jiankui, shocked the world two weeks ago when he revealed that the world’s first genetically edited babies had been born. Jiankui claimed to have edited embryos before implanting them into the mother as part of an otherwise routine in vitro fertilization (IVF) procedure. Since his bold announcement via YouTube, the scientific community at-large – both in the United States and in … Continue reading China’s Genetically Edited babies: What really happened?

Next Generation Forensics: Changing the role DNA plays in the justice system

by Mary May figures by Rebecca Clements As anyone who has watched an episode of CSI can attest, catching a killer is only a DNA sample away. Due to advances in DNA testing technology and its omnipresence in forensics (as portrayed on TV and in pop culture), the public has come to expect and trust genetic testing as evidence in criminal trials. As these methods … Continue reading Next Generation Forensics: Changing the role DNA plays in the justice system

A Tall Order: Using Machine Learning to Predict Height from Genetic Variation

A machine learning algorithm trained using 500,000 genetic profiles can predict the height of an individual within about one inch based solely on their genes. Such an algorithm shows great promise for accurate risk assessment of complex diseases and identifying targets for therapy. However, further validation is required to evaluate how the tool will extend to more genetically diverse populations, and standardized methods for assessing genetic variation are necessary. Continue reading A Tall Order: Using Machine Learning to Predict Height from Genetic Variation

The Chemistry Nobel: Evolving proteins into better medicines and biofuels

It’s that time of year – Nobel Prize season! This year, the Chemistry Nobel prize was awarded to three scientists: one half to Frances Arnold “for the directed evolution of enzymes,” and the other half to George Smith and Sir Gregory Winter “for the phage display of peptides and antibodies.” What exactly are these award-winning technologies and how have they impacted society? ‘Directed evolution of … Continue reading The Chemistry Nobel: Evolving proteins into better medicines and biofuels
