New antiplatelet drug shows promise for treating heart attack

Researchers have developed a new drug that prevents blood clots without causing an increased risk of bleeding, a common side effect of all antiplatelet medications currently available. A new study describes the drug and its delivery mechanisms and shows that the drug is also an effective treatment for heart attack in animal models.

Single drop of blood could help rapidly detect radiation sickness

A new proof-of-concept study reports evidence that a new testing method has the potential to rapidly identify radiation sickness based on biomarkers measured through a single drop of blood. Scientists say the test could help save lives through early and real-time identification of the condition to enable timely clinical interventions.

High-fat diet with antibiotic use linked to gut inflammation

Researchers have found that combining a Western-style high-fat diet with antibiotic use significantly increases the risk of developing pre- inflammatory bowel disease. This combination shuts down the mitochondria in cells of the colon lining, leading to gut inflammation. Mesalazine can help restart the mitochondria and treat pre-IBD condition.

Credit-card sized tool provides new insights into how cancer cells invade host tissues

Researchers have developed a credit-card sized tool for growing cancer cells outside the human body, which they believe will enhance their understanding of breast cancer metastasis. The device reproduces various environments within the human body where breast cancer cells live. Studying the cells as they go through the process of invasion and metastasis could point the way toward new biomarkers...

Study first to show tiger sharks' travels and desired hangouts in the Gulf of Mexico

From 2010 to 2018, scientists tagged 56 tiger sharks of varying life stages to track their movements via satellite. Movement patterns varied by life stage, sex, and season. Some of their core habitats overlapped with locations designated by NOAA as Habitat Areas of Particular Concern and also were found near 2,504 oil and gas platforms. Findings may help inform studies into potential climate...
