Simulations show ultrasound waves at medical imaging frequencies can cause the virus’ shell and spikes to collapse and rupture. The coronavirus’ structure is an all-too-familiar image, with its densely packed surface receptors resembling a thorny crown. These spike-like proteins latch onto healthy c...

A Less-Invasive Technique to Decode the Brain’s Intentions What is happening in your brain as you are scrolling through this page? In other words, which areas of your brain are active, which neurons are talking to which others, and what signals are they sending to your muscles? Mapping neural ...

AI Boosts Diagnostic Accuracy in Breast Ultrasound A computer program trained to see patterns among thousands of breast ultrasound images can aid physicians in accurately diagnosing breast cancer, a new study shows. When tested separately on 44,755 already completed ultrasound exams, the artificial ...

Researchers have combined CRISPR/Cas9 gene editing with sonodynamic therapy to overcome cancer cells’ natural antioxidant defenses, achieving a dramatic breakthrough in liver cancer treatment. Sonodynamic therapy uses ultrasound in combination with drugs to release harmful reactive oxygen species (R...

Scientists created transverse sound waves with light-like properties using micropolar metamaterials, revealing spin-orbit interactions that could transform acoustic technologies. Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) disc...

Transcranial ultrasound stimulation in macaques impacts decision-making by affecting brain regions linked to credit assignment, suggesting new approaches to psychiatric treatment. Imagine passing an exam, and thinking your success was down to the socks you wore or the number of biscuits you’d eaten,...

Salk researchers pinpoint a sound-sensitive mammalian protein that lets them activate brain, heart or other cells with ultrasound. Salk scientists have engineered mammalian cells to be activated using ultrasound. The method, which the team used to activate human cells in a dish and brain cells insid...

A new study based on recordings made by the rover finds that the speed of sound is slower on the Red Planet than on Earth and that, mostly, a deep silence prevails. Listen closely to sounds from Mars, recorded by NASA’s Perseverance: the rover’s mechanical whine and click in a light Martian wind; th...

COVID-19 Vaccine Not Associated With Birth Defects Detectable on Ultrasound Findings fill gap left vacant when pregnant people were excluded from the initial trials. Scientists analyzed ultrasounds for a wide range of birth defects from life-long and severe to short-term and mild Study advances earl...

New stamp-sized ultrasound adhesives deliver clear images of the heart, lungs, and other internal organs. When clinicians need live images of a patient’s internal organs, they often turn to ultrasound imaging for a safe and noninvasive window into the body’s workings. In order to capture these insig...
