Technology can provide a new window into whether or not patients are responding to treatment for advanced ovarian cancer. A multi-center clinical trial has demonstrated that CT Perfusion, which measures blood flow and blood volume to tumors associated with ovarian cancer, can provide an accurate prediction of how well a treatment is working, allowing physicians the opportunity to better plan treatment.
Scientists are a step closer to understanding how our DNA is squeezed into every cell in the body. They provide the first-ever detailed picture of the nucleosome, the most basic building block of chromosomes (the structures that house our DNA). This finding will inform research on all processes that involve chromosomes, such as gene expression and DNA repair, which are critical to the understanding of diseases such as cancer.
In the past, climate scientists have tended to underestimate the risk of a co-occurrence of heatwave and drought. This is the conclusion of one of the first studies to examine compound climate extremes.
Fuel from waste? It is possible. But hitherto, converting organic waste to fuel has not been economically viable. Excessively high temperatures and too much energy are required. Using a novel catalyst concept, researchers have now managed to significantly reduce the temperature and energy requirements of a key step in the chemical process. The trick: the reaction takes place in very confined spaces inside zeolite crystals.
More than 50,000 tonnes of mushroom waste are generated in Europe each week, posing an environmental challenge for the main industries that market this product worldwide. The new European project Funguschain aims to obtain high antimicrobial and antioxidant substances from these residues applicable to sectors as varied as food, cleaning or plastics.
Astronomers using NSF’s Karl G. Jansky Very Large Array (VLA) have found new evidence suggesting that a jet of fast-moving material ejected from an intermediate-mass protostar known as FIR 3 may have triggered the formation of a younger protostar, FIR 4. “The orientation of the jet, the speed of its material, and the distance all [...]
A discovery of multiple toothpick grooves on teeth and signs of other manipulations by a Neanderthal of 130,000 years ago are evidence of a kind of prehistoric dentistry, according to a new study researcher.
Stem cell research holds huge potential for medicine and human health. In particular, human embryonic stem cells (ESCs), with their ability to turn into any cell in the human body, are essential to the future prevention and treatment of disease.
A new method used to perform geochemical analysis of fossilized eggs from China has shown that oviraptorosaurs incubated their eggs with their bodies within a 35--40° C range, similar to extant birds today, scientists have discovered.
An acute heart attack should not be viewed in isolation – myocardial infarction is a "systemic" condition with an impact upon the whole body and engenders responses in other organs, such as liver and spleen, a new study concludes.
A new species of parrot has been discovered in the tropical forests of the Yucatán Peninsula, Mexico. The colorful bird was first sighted in 2014 by Mexican veterinarian and ornithologist Dr. Miguel A. Gómez Garza in a remote part of the Yucatán Peninsula in Mexico. The parrots occurred in small flocks of three to five [...]
Researchers combined gecko-inspired adhesives and a custom robotic gripper to create a device for grabbing space debris. They tested their gripper in multiple zero gravity settings, including the International Space Station.
Leaders of MIT's Abdul Latif Jameel Poverty Action Lab (J-PAL), one of world's foremost centers for antipoverty research, have developed their own formal framework for thinking about this vexing question, over the last several years. Now, in a new article, two J-PAL directors have unveiled the lab's approach.
