Researchers identify cell type that could be key to preventing marrow transplant complication

While the donor cells in a bone marrow transplant can help cure the patient's blood cancer, they can also cause graft-versus-host disease -- in which donor T cells, a specialized immune cell in the blood, attack the patient's healthy cells. Before this study, there was no finite T cell population identified as the cause of GVHD. Now, researchers have identified the specific type of T cells that...

New type of entanglement lets scientists 'see' inside nuclei

Nuclear physicists have found a new way to see inside nuclei by tracking interactions between particles of light and gluons. The method relies on harnessing a new type of quantum interference between two dissimilar particles. Tracking how these entangled particles emerge from the interactions lets scientists map out the arrangement of gluons. This approach is unusual for making use of entanglement...

Graphene grows -- and we can see it

Graphene is the strongest of all materials. On top of that, it is exceptionally good at conducting heat and electrical currents, making it one of the most special and versatile materials we know. For all these reasons, the discovery of graphene was awarded the Nobel Prize in Physics in 2010. Yet, many properties of the material and its cousins are still poorly understood -- for the simple reason...

Time of day matters when it comes to cancer diagnosis and treatment

Your circadian rhythm doesn't just govern your sleeping schedule; it can also impact cancer development, diagnosis, and treatment. Researchers discuss the role of circadian rhythms in tumor progression and spread and describe how we could better time when patients are tested for cancer and when they receive therapies to improve diagnostic accuracy and improve treatment success.

RNA vaccination in rabbit mothers confers benefits to offspring in the womb

Newly developed mRNA vaccines against Zika virus and HIV-1 produced strong antibody responses that transferred from pregnant rabbits to their offspring, researchers report. As noted by the authors, the results support further development of their vaccine platform, LIONTM/repRNA, for maternal and neonatal settings to protect against mother-to-child transmission of pathogens in animals and humans.

Dieting: Brain amplifies signal of hunger synapses

Many people who have dieted are familiar with the yo-yo effect: after the diet, the kilos are quickly put back on. Researchers have now shown in mice that communication in the brain changes during a diet: The nerve cells that mediate the feeling of hunger receive stronger signals, so that the mice eat significantly more after the diet and gain weight more quickly. In the long term, these findings...

More predictable renewable energy could lower costs

Lower electricity costs for consumers and more reliable clean energy could be some of the benefits of a new study by researchers who have examined how predictable solar or wind energy generation is and the impact of it on profits in the electricity market.

Finding the sweet spot in sugar reductions

Putting less sugar in sodas and reducing the package size of sodas sold in supermarkets may help reduce our collective sugar intake and thus lower the associated health risks. Good news for consumers, but how does it affect manufacturers? Research conducted in the US has shown that marketing diet or sugar-free varieties does not lead to an increase in the overall turnover of soda manufacturers....

Use age, not weight, to screen for diabetes

Focus on age, not weight, to capture the greatest number of people in all racial and ethnic groups with prediabetes and diabetes, reports a new study. Screening all adults aged 35 to 70 years, regardless of weight, identifies the greatest proportion of adults with prediabetes and diabetes in the U.S. This approach will also maximize the ability to diagnose prediabetes and diabetes across all...
