Handgun licensing more effective at reducing gun deaths than background checks alone
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.

The power of a love song: Dopamine affects seasonal hearing in fish and facilitates mating
Many people associate dopamine with reward or attention. Some might think of the part it plays in addiction, or Parkinson's disease, which kills off dopamine-making neurons.

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.

Researchers find effective drug combinations for glioblastoma in mice
Usually, scientists study the molecular biology of cancer to find new treatments, but sometimes, it is the other way around: When seeking new treatments, scientists find key information on cancer biology. The researchers from the Telomeres and Telomerase Group at the Spanish National Cancer Research Centre (CNIO) have identified new drug combinations that prevent the development of therapy resistance in mice with glioblastoma, the most malignant brain tumor. They also found an unexpected link between the RAS pathway, which is involved in numerous types of cancer, and telomere maintenance. This finding, which could be used in new lines of research, will be published in the medical journal EMBO Molecular Medicine.

The three big studies pushing at the frontiers of HIV prevention
There are an estimated 5000 new HIV transmissions every day. Around 70% of the 37 million people living with HIV globally are in sub-Saharan Africa. Of the 1.8 million new HIV transmissions worldwide in 2017, 800 000 occurred in eastern and southern Africa. New, effective prevention strategies are essential to reducing HIV transmission.

Holistic view of planning energy self-sufficient communities
Sustainable communities supplied by local renewable energy production are beginning to be established in the U.S. By using energy-efficient buildings and distributing means of energy generation, such as solar panels, throughout buildings in these districts, the communities manage to produce enough energy for their local needs—achieving a yearly net zero energy (NZE) balance.

Selective logging will not be enough to sustain timber production in Amazonia
Amazonian forests are unlikely to provide enough timber to meet current demand over the long term, even with the use of improved logging practices.
