To search for answers about how blood droplets from a gunshot wound can reverse direction while in flight, researchers explored the influence of propellant gases on blood backspatter. They report using numeric modeling to capture the behavior of gun muzzle gases and predict the reversal of blood droplet flight, which was captured experimentally. Their experiments…

New research has identified that the frequently used chemotherapy drug (5-FU or Fluorouracil) is 100 per cent more effective at targeting tumors (rather than surrounding tissues) when administered using an optimized liposomal formulation. Now, world first research conducted by the University of South Australia has identified that the frequently used chemotherapy drug (5-FU or Fluorouracil)…

A research collaboration can read out optically previously indistinguishable spin states by using a newly developed spectroscopy method. Normally, electrons in a molecule occupy the quantum theoretically allowed orbits pairwise. The property of the electrons’ intrinsic angular momentum, their spin, is of pivotal importance here. According to the Pauli exclusion principle of quantum mechanics, two…

A team of engineers has invented new technology that could forever change the manufacturing of wearable, electronic sensors. They’ve figured out a way to speed up production without having to use polymer binders — the industry standard in printing flexible sensors, which are often used to monitor vital signs in health care settings. Their technology,…

In analogy to the amplification of light in a laser, vibrations of a semiconductor crystal, so called phonons, were enhanced by interaction with an electron current. Excitation of a metal-semiconductor nanostructure by intense terahertz (THz) pulses results in a ten-fold amplification of longitudinal optical (LO) phonons at a frequency of 9 THz. Coupling such lattice…

A novel MRI-guided procedure that uses therapeutic ultrasound effectively treats prostate cancer with minimal side effects, according to a new study. Researchers said the incision-free technique could also be used to treat benign enlargement of the prostate gland. Prostate cancer is the second-leading cause of cancer death in men after lung cancer. Treating disease in…

Focused ultrasound, the researchers hope, could revolutionize treatment for conditions from Alzheimer’s to epilepsy to brain tumors — and even help repair the devastating damage caused by stroke. Richard J. Price, PhD, of UVA’s School of Medicine and School of Engineering, is using focused soundwaves to overcome the natural «blood-brain barrier,» which protects the brain…

Engineering researchers have developed a new technique for eliminating particularly tough blood clots, using engineered nanodroplets and an ultrasound ‘drill’ to break up the clots from the inside out. The technique has not yet gone through clinical testing. In vitro testing has shown promising results. Specifically, the new approach is designed to treat retracted blood…

Prediction models based on clinical characteristics and imaging findings may help reduce the false-positive rate in women with dense breasts who undergo supplemental breast cancer screening with MRI, according to a new study. Women with dense breast tissue have a much higher risk of breast cancer compared to those with average breast density. High breast…

Researchers have developed a device that detects viruses in the body as fast as and more accurately than current, commonly used rapid detection tests. The optical sensor uses nanotechnology to accurately identify viruses in seconds from blood samples. Researchers say the device can tell with 95 percent accuracy if someone has a virus. The optical…
