- Physicists discover a new approach for building quantum computers
The main reason why quantum computers are so hard to manufacture is that now scientists still haven't find a simple way to control complex systems of qubits. This research discovers a different approach:Instead of uniting multiple two-state systems into one, authors use one system with multiple states. This approach proves to be more effiective, since it is easier to make a stable multi-level system, than to maintain stability in a complex system.

- Historical records miss a fifth of global warming: NASA
A new NASA-led study finds that almost one-fifth of the global warming that has occurred in the past 150 years has been missed by historical records due to quirks in how global temperatures were recorded. The study explains why projections of future climate based solely on historical records estimate lower rates of warming than predictions from climate models.
- Football concussion update: Player-on-player hits cause more serious head impacts
In football, player-vs.-player hits will likely cause more severe head impacts than other impacts, according to a new study.
- Trees' surprising role in the boreal water cycle quantified
This is the first study to show that deciduous tree water uptake of snowmelt water represents a large but overlooked aspect of the water balance in boreal watersheds. For the boreal forest of Alaska and Western Canada, this equates to about 17-20 billion cubic meters of water per year. That is roughly equivalent to 8-10 percent of the Yukon River's annual discharge.
- Biologists home in on paleo gut for clues to our evolutionary history
A new study of the gut microbiomes of humans, chimps, bonobos and gorillas shows that at least two major groups of bacteria have cospeciated with these hosts, with a lineage going back at least 15 million years to our last common ancestor. Researchers hope to reconstruct the ancestral 'paleo gut' that went with our paleo diet, and use the gut bacteria to track human migration.

- More doesn't mean better when it comes to trauma centers
For the first time, research shows that changes over time in the volume of patients seen by trauma centers influence the likelihood of seriously injured patients living or dying. The findings mean that changes in patient volume across all affected centers should be considered when designating a new trauma center in a region.
- Predatory prawns eliminate a major parasite more effectively than drugs alone
A new study upends the status quo to combatting schistosomiasis, which affects 250 million people worldwide. The team suggests that the spread of the parasitic disease is curbed more effectively with ecological intervention than drug treatment alone.
- Temperature helps drive the emergence of different personalities in spiders
Not a single aggressive spider was able to reproduce at 93 degrees Fahrenheit and most of them died at that temperature. But when researchers added docile spiders to the mix, the aggressive spiders thrived in that diverse community at that temperature.
