Mathematician's study of 'swarmalators' could direct future science
How does the Japanese tree frog figure into the latest work of noted mathematician Steven Strogatz? As it turns out, quite prominently. Cornell researchers used the curious mating ritual of male Japanese tree frogs as inspiration for their exploration of 'swarmalators' -- their term for systems in which both synchronization and swarming occur together.

Carefully crafted light pulses control neuron activity
Specially tailored, ultrafast pulses of light can trigger neurons to fire and could one day help patients with light-sensitive circadian or mood problems, according to a new study in mice at the University of Illinois. This study is the first demonstration of using coherent control to regulate function in a living cell.

Brain activity buffers against worsening anxiety
Boosting activity in brain areas related to thinking and problem-solving may also protect against worsening anxiety, suggests a new study by Duke University scientists. Using noninvasive brain imaging, the researchers found that at-risk people were less likely to develop anxiety if they had higher activity in a region of the brain responsible for complex mental operations. The results may be a step towards tailoring psychological therapies to the specific brain functioning of individual patients.

Nearby pulsars shed light on the antimatter puzzle
There are too many high-energy positrons in the cosmic rays reaching the Earth. These positrons (particles that are antimatter equivalents of electrons) could be being produced by pulsars in our vicinity. The most recent measurements from the HAWC Observatory in Mexico have practically excluded this possibility, strengthening the competing and much more exotic hypothesis concerning the origin of the excess positrons.

Spanking linked to increase in children's behavior problems
Children who have been spanked by their parents by age 5 show an increase in behavior problems at age 6 and age 8 relative to children who have never been spanked, according to new findings in Psychological Science. The study, which uses a statistical technique to approximate random assignment, indicates that this increase in behavior problems cannot be attributed to various characteristics of the child, the parents, or the home environment - rather, it seems to be the specific result of spanking.

Groundwater recharge in the American west under climate change
Groundwater recharge in the Western US will change as the climate warms -- the dry southern regions will have less and the northern regions will have more, according to new research. The new study covers the entire US West, from the High Plains states to the Pacific coast, and provides the first detailed look at how groundwater recharge may change as the climate changes. Groundwater is an important source of freshwater, particularly in the West.

Researchers find diffusion plays unusual signaling role in drosophila embryos
Researchers have found that diffusion plays an unexpected role in cell differentiation during the early stages of development in the embryos of Drosophila, or fruit flies. Instead of spreading a molecular signal out, it was found that diffusion, facilitated through a carrier molecule, actually concentrates the signal in one place.

New research could predict La Niña drought years in advance
Two new studies from The University of Texas at Austin have significantly improved scientists' ability to predict the strength and duration of droughts caused by La Niña - a recurrent cooling pattern in the tropical Pacific Ocean. Their findings, which predict that the current La Niña is likely to stretch into a second year, could help scientists know years in advance how a particular La Niña event is expected to evolve.

Genomic study explores evolution of gentle 'killer bees' in Puerto Rico
A study of Puerto Rico's Africanized honey bees -- which are more docile than other so-called 'killer bees' -- shows they retain most of the genetic traits of their African honey bee ancestors, but that a few regions of their DNA have become more like those of European honey bees. These changes likely contributed to the bees' rapid evolution toward gentleness in Puerto Rico, a change that occurred within 30 years, and could spell hope for beekeeping in North America.

High-altitude observatory sheds light on origin of excess anti-matter
Researchers working with the High-Altitude Water Cherenkov (HAWC) Gamma-Ray Observatory have made the first detailed measurements of two pulsars suspected as the source of a mysterious positron accumulation near Earth. Despite being the right age and the right distance from Earth, the pulsars lie within an extended murky cloud that prevents most positrons from escaping. The results suggest there must be an alternate explanation for the positron excess -- perhaps one involving dark matter.

Study reveals structure and origins of glacial polish on Yosemite's rocks
The glaciers that carved Yosemite Valley left highly polished surfaces on many of the region's rock formations. These smooth, shiny surfaces, known as glacial polish, are common in the Sierra Nevada and other glaciated landscapes. Geologists at UC Santa Cruz have now taken a close look at the structure and chemistry of glacial polish and found that it consists of a thin coating smeared onto the rock as the glacier moved over it.

Genome of wheat ancestor sequenced
Sequencing the bread wheat genome has long been considered an almost insurmountable task, due to its enormous size and complexity. Now, an international team of scientists led by researchers at the University of California, Davis, has come a step closer to solving the puzzle by sequencing the genome of a wild ancestor of bread wheat known as Aegilops tauschii, a type of goatgrass.

Colorado River's connection with the ocean was a punctuated affair
The Colorado River's initial trip to the ocean didn't come easy, but its story has emerged from layers of sediment preserved within tectonically active stretches of the waterway's lower reaches. University of Oregon researchers theorize that the river's route off the Colorado Plateau was influenced by tectonic deformation and changing sea levels that produced a series of stops and starts between roughly 6.3 and 4.8 million years ago.

WPI research detects when online reviews and news are a paid-for pack of lies
A researcher at Worcester Polytechnic Institute (WPI) is using computer science to help fight the growing problem of crowdturfing -- a troublesome phenomenon in which masses of online workers are paid to post phony reviews, circulate malicious tweets, and even spread fake news. Assistant professor Kyumin Lee has developed algorithms that have proven highly accurate in detecting fake 'likes' and followers across various platforms like Amazon, Facebook, and Twitter.

NUS researchers identify potential mediator for social memory formation
The ability to form long-term social memories is essential for remembering faces and developing social bonds. Scientists at NUS Medicine have now discovered that the tiny CA2 region in the hippocampus is involved in the linking up of memory fragments (consolidation) to form long-term memories, and that a neuropeptide, substance P, is involved in this process. Since CA2 is responsible for social memory, this finding has significant implications for how long-term social memories are formed.
