Elephants imitate sounds as a form of social communication

Elephants learn to imitate sounds that are not typical of their species, the first known example after humans of vocal learning in a non-primate terrestrial mammal. The discovery, reported in today's Nature, further supports the idea that vocal learning is important for maintaining individual social relationships among animals that separate and reunite over time, like dolphins and whales, some bi...

Pulsating ultrasound enhances gene therapy for tumors

High-intensity focused ultrasound emitted in short pulses is a promising, non-invasive procedure for enhancing gene delivery to cancerous cells without destroying healthy tissue, according to a study in the May issue of the journal Radiology. High-intensity focused ultrasound (HIFU) is more powerful than standard ultrasound. HIFU can destroy tumors through long and continuous exposures tha...

How fish hear and make sounds at same time

Cornell University researchers have learned how a common fish found along the West Coast can hum and hear outside sounds at the same time. The study marks the first time that scientists have found a direct line of communication between the part of a vertebrate's brain that controls the vocal muscle system and the part of the ear that hears sound. The researchers believe that understanding...

Penn researchers study the use of ultrasound for treatment of cancer

For the first time, ultrasound is being used in animal models ?to treat cancer by disrupting tumor blood vessels. Researchers at the University of Pennsylvania School of Medicine completed a study in mice in which they used ultrasound both to see a tumor's blood perfusion and then to treat it with a continuous wave of low-level ultrasound. After three minutes of treatment at an intensity similar...

Bird song changes sound alarm over habitat fragmentation

Changes in bird song could be used as an early warning system to detect man-made ecological disturbances, new research published in the British Ecological Society's Journal of Applied Ecology has found. Although much previous research has focused on bird song and vocal mimicry, this is the first study to analyse the role played by habitat loss and fragmentation on song-matching. Ecologists...

Sound Focus plans to enter home-entertainment market after taking Governor's prize

Sound Focus has a plan: rework home entertainment with a speaker system that can project different sounds to different places without complicated acoustic engineering. That plan won top honors in the information technology category at Wisconsin Gov. Jim Doyle's first annual business-plan contest. But for now, Sound Focus is another start-up looking for enough funding to kick-start its en...

Ultrasound helps stroke treatment

According to surgeons, they use sound waves to pulverize gallstones and now stroke experts are trying to determine if less powerful ultrasound can improve the efficacy of the clot-busting drugs used to restore blood flow to the brain.// Dr. Andrei Alexandrov, of the University of Texas, said he was using intracranial ultrasound to track the efficacy of the clot-busting drug called tPA or alteplas...

Ultrasound test may detect heart condition early

According to a new report, a type of ultrasound test may be able to identify patients with a heart condition that is one of the most common causes of sudden death in young people.The condition, hypertrophic cardiomyopathy (HCM), can be caused by more than 100 different mutations in as many as 10 genes. In HCM, the heart muscle thickens, eventually limiting the organ's ability to pump blood and pu...

Adding contrast improves ultrasound's ability to detect prostate cancer

Contrast enhanced color Doppler ultrasound is better than unenhanced ultrasound at detecting prostate cancer, according to a report published in the July issue of The Journal of Urology. Doctors in France, compared the diagnostic abilities of contrast enhanced and unenhanced endo-rectal ultrasound in 85 men suspected of having prostate cancer. In all subjects, the imaging findings were com...

Ultrasound Screening Could Improve The Outcome Of Critically ill Patients

New research finds ultrasound screening is cost effective and could help in the prevention of blood clots or venous thrombosis.The research focuses on patients who have a catheter in the main artery in their thigh called the femoral artery.// Almost half of the 31 million patients admitted into the intensive care unit each year receive a central venous catheter. It’s estimated femoral vein...

The Safety Of Prenatal Ultrasounds Questioned

Repeated ultrasound exposures during pregnancy may not cause long-term harm to infants, according to a new study. // For the study 2,700 children were evaluated, half of whom had been exposed to repeated ultrasound and half of whom had only one ultrasound exposure before birth. The children were followed up at 1, 2, 3, 5 and 8 years of age. While researchers note there may be a slight ef...
