by Sydney Sherman figures by Aparna Nathan More likely than not, you or someone you know has taken a genetic test. Whether they are curious about their ethnic roots and family tree or want to determine their risk for developing a certain disease, consumers have access to genetic testing as a simple “spit-and-send” process. We use the technology and rely on the results, but how … Continue reading What can we learn from a genetic test?
by Aparna Nathan figures by Abagail Burrus Superheroes aren’t the only ones with riveting origin stories. As humans, where did we come from? How did we populate six continents? For hundreds of years, archaeology has tried to provide the answers by digging up artifacts and piecing together their histories. However, shovels and brushes are now joining forces with test tubes and lab coats. Within the … Continue reading Digging for DNA: Ancient genomes can illuminate the past and reframe the present
Scientists have developed a biodegradable ultrasound speaker that can be placed inside the brain. When activated, it makes the blood-brain barrier permeable, potentially allowing certain drugs such as brain cancer chemotherapy and antidepressants to reaching their destination more easily. Continue reading Ultrasound speaker implant that can open a door to your brain
CRISPR is a highly effective immune system that defends bacteria from viruses. It was recently shown that some viruses have evolved counter-defenses that protect their DNA with a nucleus-like structure. Continue reading Some viruses can defeat CRISPR with nucleus-like compartments
A new study takes a crack at trying to predict someone’s face using just their DNA. Continue reading A Rough Portrait of Your Face, Painted by your DNA
Scientists at ETH Zurich recently developed a storage architecture using DNA, where they fused DNA into everyday objects in order to store data. Continue reading Artificial DNA can replace your thumb drive
Genes delivered by a virus successfully mitigated the effects of age-related diseases, such as heart and kidney disease, in a recent mouse study. Following this success, a similar gene therapy treatment is in trial to prevent a certain form of heart disease in dogs. Continue reading Gene therapy that helps prevent heart disease in mice now in trial for dogs
Sutures are commonly used to close wounds in the skin or other tissues. Similar to sewing fabric, the doctors will use a needle attached to a thread to penetrate the tissue and close the edges of the wound together, facilitating quick healing. Although surgical sutures have been used for thousands of years, they still have some limitations: 1) the needles cause some damage to the … Continue reading ‘Double-sided tape’ could replace surgical stitches
Brain-machine interfaces translate brain signals into information that can be used to control robotic limbs, and now even predict an individual’s mood state. Researchers envision using BMIs together with electrical stimulation, to regulate abnormal brain signals in patients with treatment-resistant neuropsychiatric disorders. Continue reading Brain-machine interfaces may be used to study and regulate mood
A new study deems mother of pearl or nacre to be the toughest material. Under pressure, nacre’s structure deforms to withstand force and then retains its original form when released. Unlike plastic, the material also fully recovers its strength once released. Continue reading The science behind mother of pearl: what makes Nacre the mother of materials
