A new white paper from the Johns Hopkins Center for Gun Policy and Research at the Johns Hopkins Bloomberg School of Public Health concludes that of the approaches used by states to screen out prohibited individuals from owning firearms, only purchaser licensing has been shown to reduce gun homicides and suicides. Purchaser licensing is currently used by nine states and Washington, D.C.

Empirical energy consumption model quantifies Bitcoin's carbon footprint
Researchers have conducted the first analysis of Bitcoin power consumption based on empirical data from IPO filings and localization of IP addresses. They found that the cryptocurrency's carbon emissions measure up to those of Kansas City—or a small nation. The study, published June 12 in the journal Joule, suggests that cryptocurrencies contribute to global carbon emissions, an issue that must be considered in climate change mitigation efforts.

Downward head tilt can make people seem more dominant
We often look to people's faces for signs of how they're thinking or feeling, trying to gauge whether their eyes are narrowed or widened, whether the mouth is turned up or down. But findings published in the June 2019 issue of Psychological Science, a journal of the Association for Psychological Science, show that facial features aren't the only source of this information—we also draw social inferences from the head itself.

Genes for Good project harnesses Facebook to reach larger, more diverse groups of people
In 2015, a group of researchers hypothesized that our collective love of Facebook surveys could be harnessed for serious genetic studies. Today, the Genes for Good project (@genesforgood) has engaged more than 80,000 Facebook users, collected 27,000 DNA spit-kits, and amassed a trove of health survey data on a more diverse group of participants than has previously been possible. Researchers say their app could work as a model for studies on an even larger scale. Their work appears June 13 in The American Journal of Human Genetics.

Teaching AI agents navigation subroutines by feeding them videos
Researchers at UC Berkeley and Facebook AI Research have recently proposed a new approach that can enhance the navigation skills of machine learning models. Their method, presented in a paper pre-published on arXiv, allows models to acquire visuo-motor navigation subroutines by processing a series of videos.

Solving the mystery of why atmospheric carbon dioxide was lower during ice ages
Since scientists first determined that atmospheric carbon dioxide (CO2) was significantly lower during ice age periods than warm phases, they have sought to discover why, theorizing that it may be a function of ocean circulation, sea ice, iron-laden dust or temperature.

Novel denoising method generates sharper photorealistic images faster
Monte Carlo computational methods are behind many of the realistic images in games and movies. They automate the complexities in simulating the physics of lights and cameras to generate high-quality renderings from samples of diverse image features and scenes. But the process of Monte Carlo rendering is slow and can take hours—or even days—to produce a single image, and oftentimes the results are still pixelated, or "noisy."

Sickle cell disease needs more attention
The promise of new treatments for sickle cell disease, a group of inherited red blood cell disorders, has never been so great, but it will only be realized if there is constant investment in health policies such as programs for screening newborns, especially in sub-Saharan Africa, where most cases occur.

Are we using biologic therapy properly?
The introduction of infliximab (Remicade), the first biologic therapy approved for the treatment of inflammatory bowel diseases (IBD), did not result in lower rates of hospitalizations or intestinal surgeries among patients living with IBD in Ontario, according to a study published by authors from several Canadian hospitals and ICES in the journal Gut.
