RESTON, VA - Researchers have discovered a new nuclear medicine test that could improve care of patients with type 1 diabetes. The new positron emission tomography (PET) imaging method could measure beta-cell mass, which would greatly enhance the ability to monitor and guide diabetes therapies. This study is reported in the featured article of the month in The Journal of Nuclear Medicine's August issue.
CHAMPAIGN, Ill. -- A new study reveals that all insects use specialized odorant receptors that enable them to detect and pursue mates, identify enemies, find food and - unfortunately for humans - spread disease. This puts to rest a recent hypothesis that only some insects evolved the ability to detect airborne odors as an adaptation to flight, the researchers said.
The findings are reported in the journal eLife.
In an article published July 17, 2018 by Nature Communications, a highly collaborative team of researchers at the Medical University of South Carolina (MUSC) and Ohio State University report that normal breast cells can prevent successful radiation treatment of breast cancer due to dysregulation between tumor suppressors and oncogenes. Tumor suppressors act like brakes that stop cells from undergoing uncontrolled growth, while oncogenes are the gas pedal. The tumor suppressor gene of interest in this study is PTEN, which is often mutated in human cancer cells.
In "The Politics of Selecting the Bench from the Bar: The Legal Profession and Partisan Incentives to Introduce Ideology into Judicial Selection," published in the Journal of Law and Economics, Adam Bonica and Maya Sen analyze how and why American courts become politicized. The authors present a theory of strategic selection in which politicians appoint judges with specific ideological backgrounds in order to advance political agendas.
Inhibiting the Jagged 1 protein in mice prevents the proliferation and growth of colon and rectal tumours. What is more, this approach to the disease permits the removal of existing tumours.
Researchers have determined that new mothers exposed to cigarette smoke in their homes, stop breastfeeding sooner than women not exposed to second-hand smoke.
The study, conducted in Hong Kong, involved more than 1,200 women from four large hospitals, explains Professor Marie Tarrant, Director of UBC Okanagan's School of Nursing. Tarrant, whose research focuses on maternal and child health, taught in the faculty of Medicine in the University of Hong Kong before joining UBC.
The vast reservoir of carbon stored beneath our feet is entering Earth's atmosphere at an increasing rate, most likely as a result of warming temperatures, suggest observations collected from a variety of the Earth's many ecosystems.
Blame microbes and how they react to warmer temperatures. Their food of choice - nature's detritus like dead leaves and fallen trees - contains carbon. When bacteria chew on decaying leaves and fungi chow down on dead plants, they convert that storehouse of carbon into carbon dioxide that enters the atmosphere.
Tsukuba, Japan - Placodes and neural crests are defining features of vertebrates (animals with a spinal cord surrounded by cartilage or bone). Placodes are embryonic structures that develop into sensory organs such as ear, nose, and lens cells, while neural crests develop into various cell lineages such as bone, craniofacial cartilage, and epidermal sensory neurons.
ALBUQUERQUE, N.M. -- Using an artful combination of nanotechnology and basic chemistry, Sandia National Laboratories researchers have encouraged gold nanoparticles to self-assemble into unusually large supercrystals that could significantly improve the detection sensitivity for chemicals in explosives or drugs.
"Our supercrystals have more sensing capability than regular spectroscopy instruments currently in use, just like a dog's nose has more sensing capabilities than a human's," said lead Sandia researcher Hongyou Fan.
Differences in social status and political belief increase paranoid interpretations of other people's actions, finds a new UCL experimental study.
Paranoia is the tendency to assume other people are trying to harm you when their actual motivations are unclear, and this tendency is increased when interacting with someone of a higher social status or opposing political beliefs, according to the study published today in Royal Society Open Science.
CLEVELAND--Researchers at Case Western Reserve University are using wearable sensor technology to develop an automatic alert system to help people quit smoking.
The smart-phone app, initially limited to android-based operating systems, automatically texts 20- to 120-second video messages to smokers when sensors detect specific arm and body motions associated with smoking.
There is no shortage of products or programs--from nicotine gum to hypnosis--to help people stop smoking. More recently, wearable technology has gained popularity in the fight against addiction.
A stalled weather pattern led to persistent showers and thunderstorms moving up the eastern seaboard during the week of July 22, resulting in significant rainfall amounts and numerous flood warnings. NASA utilized satellite data to analyze and tally the rainfall from the storms.
Carolyn Elya discovered the puppet-master on the balcony of her Berkeley apartment. It was a fungus that infects fruit flies, invading their nervous system and eating them from the inside out.
In their death throes, the infected flies - like puppets on a string - obligingly climb to a high point and spread their wings, exposing their abdomen and allowing the fungus to shoot its spores as widely as possible to infect new flies.
July 31, 2018 - Three-dimensional image simulation is popular among women planning breast augmentation surgery.
Pioneering new research into the way in which cells communicate with each other could hold the key to unlocking new, improved treatment for life-threatening diseases, including cancer.
Various mechanisms exist for cells to communicate with each other, and many are essential for development. A team of international researchers looked at how one important family of signalling molecules - Wnt proteins, which orchestrate and control many cell development processes - are transported between cells.
