An online game in which people play the role of propaganda producers to help them identify real world disinformation has been shown to increase "psychological resistance" to fake news, according to a study of 15,000 participants.

Adding clinical variables improves accuracy of lung allocation score
Implemented back in 2005, the lung allocation score is used to prioritize patients awaiting lung transplants in the United States. Sicker transplant candidates have a higher calculated score and are placed at the top of the list. But a recent study led by Maryam Valapour, M.D., MPP, director of Lung Transplant Outcomes in Cleveland Clinic's Respiratory Institute, found including new clinical variables helped to better identify the sickest cystic fibrosis and chronic obstructive pulmonary disease (COPD) patients awaiting transplants.

Virtual reality faces—animating precise, lifelike avatars for VR in real-time
Computer scientists are focused on adding enhanced functionality to make the "reality" in virtual reality (VR) environments highly believable. A key aspect of VR is to enable remote social interactions and the possibility of making it more immersive than any prior telecommunication media. Researchers from Facebook Reality Labs (FRL) have developed a revolutionary system called Codec Avatars that gives VR users the ability to interact with others while representing themselves with lifelike avatars precisely animated in real-time. The researchers aim to build the future of connection within virtual reality, and eventually, augmented reality by delivering the most socially engaged experience possible for users in the VR world.

Which climates are best for passive cooling technologies?
A group of University of California, San Diego researchers set out to gain a better understanding of the thermal balance of power plants and surfaces, like heliostat mirrors or solar panels, when exposed to both solar (shortwave) and atmospheric (longwave) radiation. They quickly realized that they would first need to determine what roles cloud cover and relative humidity play in the transparency of the atmosphere to radiation at temperatures common on Earth.

Apple launches iOS 13 public beta: 10 reasons to get the software now if you're feeling brave
Apple will unveil new iPhones in September, assuming the company sticks to its usual playbook. The fall timeframe is also when Apple officially releases the latest flavor of iOS, the software that will not only be at the core of whatever new handsets Apple introduces, but that will also add fresh features to the iPhones already out in the wild, likely including the phone in your pocket.

Artificial intelligence learns to recognize nerve cells by their appearance
Is it possible to understand the brain? Science is still far from answering this question. However, since researchers have started training artificial intelligence on neurobiological analyses, it seems at least possible to reconstruct the cellular structure of a brain. New artificial neural networks developed by the Max Planck Institute of Neurobiology and Google AI can now even recognize and classify nerve cells independently based on their appearance.

Voxelotor improves hemoglobin levels in sickle cell disease
(HealthDay)—For individuals with sickle cell disease, 1,500 mg of voxelotor increases hemoglobin levels and reduces the incidence of worsening anemia compared with placebo, according to a study published in the June 14 issue of the New England Journal of Medicine.

Researchers create multi-junction solar cells from off-the-shelf components
Multi-junction solar cells are both the most efficient type of solar cell on the market today and the most expensive type of solar cell to produce. In a proof-of-concept paper, researchers from North Carolina State University detail a new approach for creating multi-junction solar cells using off-the-shelf components, resulting in lower cost, high-efficiency solar cells for use in multiple applications.

De-escalating breast cancer therapy—can some patients be spared chemotherapy?
About one of every five breast cancers presents with high levels of HER2 proteins. Known as HER2-positive breast cancer, these tumors typically show an aggressive behavior—a greater likelihood of metastasis and relapse and decreased patient survival than HER2 negative types—and are physiologically dependent on the abundance of HER2. These findings prompted the question, if we take HER2 away from 'HER2-addicted' cancers, would cancer slow down?

Perovskite solar cells tested for real-world performance—in the lab
It was only ten years ago that metal-halide perovskites were discovered to be photovoltaic materials. Today, perovskite solar cells are almost as efficient as the best conventional silicon ones, and there is much hope that they will become a highly efficient and low-cost alternative, as they can be manufactured by rather simple and fast methods like printing.

Ant farmers boost plant nutrition
Humans began cultivating crops about 12,000 years ago. Ants have been at it rather longer. Leafcutter ants, the best-known insect farmers, belong to a lineage of insects that have been running fungus farms based on chopped-up vegetable matter for over 50 million years. The ant farming of flowering plants, however, started more recently, about 3 million years ago in the Fiji Islands.

Transfusion dose density affects myelodysplastic syndrome survival
(HealthDay)—Transfusion dose density is an independent prognostic factor for progression-free survival (PFS) in patients with myelodysplastic syndromes treated with red blood cell transfusions (RBCTs), according to a study published online June 6 in Haematologica.
