A US study by University of Washington social demographers finds that joblessness is the key predictor of violent death among working-age Americans in Chicago. The research analyzed census data and vital records, revealing a strong link between economic disadvantage and mortality rates.
A new MIT software has significantly improved the accuracy of a robotic system used in cancer treatment, reducing errors from 7-8mm to under 1/3mm. This breakthrough technology has potential applications beyond cancer therapy, including inspection and repair work in nuclear power facilities.
Researchers at Johns Hopkins University have developed an algorithm that enables computers to filter out unwanted material and locate land mines in surveillance images with a high degree of accuracy. The system uses size and shape restrictions, as well as optical frequencies, to distinguish between mines and other objects.
For the first time, researchers have analyzed polar stratospheric cloud particles using a developed instrument. The results show water-rich particles with high H2O/nitric acid ratios, challenging previous assumptions about PSC composition.
A large study has identified a microscopic change in breast tissue that may double the risk of breast cancer in some women. Radial scars were found in nearly 100 out of 1,400 women with benign breast biopsies, doubling their risk of breast cancer independently of other tissue abnormalities.
A team of researchers has devised a way to track Antarctic Weddell seals as they hunt using a small video system and data logger attached to their backs. The equipment enables the researchers to compute the three-dimensional path of individual dives, allowing for major advancements in understanding underwater behavior.
Scientists have found that deformation can bypass the sound barrier in materials, leading to supersonic dislocations. These findings challenge conventional wisdom and open up new avenues for understanding high-speed deformation in engineering materials.
The US blood supply is considered extremely safe, with the risk of contracting viruses such as HIV being estimated at one in 676,000. However, a growing aging population will lead to increased demands on the blood supply, resulting in a potential shortage, and more units may need to be imported from abroad.
Researchers found that one-time H pylori screening could save thousands of lives due to the high mortality rate of gastric cancer. The study suggests that a simple blood test followed by antibiotics can effectively reduce cancer risk at an affordable cost.
Researchers have discovered that combining standard treatment with a second natural hormone, triiodothyronine, improves cognitive symptoms in hypothyroidism patients. The study found that brain function, memory, and energy levels increased significantly with the combined therapy.
