Stricter US state gun laws linked to safer high schools  

Adopting stricter state gun laws is linked to a safer school experience for students, a new study has found. Strengthening gun laws at state level was associated with teens being less likely to report being threatened or injured with a weapon at school, miss at least one day of school due to feeling unsafe, or to carry a weapon at any location.

The ongoing climate changes make it increasingly difficult to predict certain aspects of weather, according to a new study. The study, focusing on weather forecasts in the northern hemisphere spanning 3-10 days ahead, concludes that the greatest uncertainty increase will be regarding summer downfalls, of critical importance when it comes to our ability to predict and prepare for flooding.

A new system can monitor the behavior of all electric devices within a building, ship, or factory, determining which ones are in use at any given time and whether any are showing signs of an imminent failure. When tested on a Coast Guard cutter, the system pinpointed a motor with burnt-out wiring that could have led to a serious onboard fire.

Similar to the dozens of Sherpas that guide hikers up treacherous Himalayan mountains to reach a summit, the nervous system relies on elaborate timing and location of guidance cues for neuronal axons -- threadlike projections -- to successfully reach their destinations in the body. Now, researchers discover how neurons navigate a tricky cellular environment by listening for directions, while simultaneously filtering out inappropriate instructions to avoid getting lost.

Tall ice-cliffs may trigger big calving events -- and fast sea-level rise  

Glaciers that drain ice sheets such as Antarctica or Greenland often flow into the ocean, ending in near-vertical cliffs. As the glacier flows into the sea, chunks of the ice break off in calving events. Although much calving occurs when the ocean melts the front of the ice, and ice cliff above falls down, a new study presents another method of calving: slumping. And this process could break off much larger chunks of ice at a quicker rate.

In a new quantum simulator, light behaves like a magnet  

Physicists propose a new 'quantum simulator': a laser-based device that can be used to study a wide range of quantum systems. Studying it, the researchers have found that photons can behave like magnetic dipoles at temperatures close to absolute zero, following the laws of quantum mechanics. The simple simulator can be used to better understand the properties of complex materials under such extreme conditions.

The evolution of brain tumors  

Scientists have found in a recent study that only three different genetic alterations drive the early development of malignant glioblastomas. At least one of these three cancer drivers was present in all tumors investigated. The tumors develop for up to seven years before they become noticeable as symptoms and are diagnosed. However, in contrast to their early development, glioblastomas, which return after therapy, share no concurrent genetic alterations.
