FACES OF WATER
Amazing Photo Technique Reveals Water Like You’ve Never Seen It Before

It’s easy to lose an hour staring into a campfire. Water, that other life-giving thing, doesn’t often captivate us in quite the same way. These photographs by Moses Hacmon, however, show just how entrancing water can truly be. Using a novel process that captures the movement of water directly, instead of just documenting the light bouncing off it, they give us an intimate look at the most familiar of liquids.

Dolphins Have Longest Memories in Animal Kingdom
Marine mammals can remember their friends after 20 years apart, study says.
New experiments show that bottlenose dolphins can remember whistles of other dolphins they’d lived with after 20 years of separation. Each dolphin has a unique whistle that functions like a name, allowing the marine mammals to keep close social bonds.
The new research shows that dolphins have the longest memory yet known in any species other than people. Elephants and chimpanzees are thought to have similar abilities, but they haven’t yet been tested, said study author Jason Bruck, an animal behaviorist at the University of Chicago.
Bruck came up with the idea to study animal memory when his brother’s dog, usually wary of male strangers, remembered and greeted him four years after last seeing him. “That got me thinking: How long do other animals remember each other?”
I Remember You!
Bruck studied dolphins because their social bonds are extremely important and because there are good records for captive dolphins (as opposed to wild ones).
So he collected data from 43 bottlenose dolphins at six facilities in the U.S. and Bermuda, members of a breeding consortium that has swapped dolphins for decades and kept careful records of each animal’s social partners.
He first played recordings of lots of unfamiliar whistles to the dolphins in the study until the subjects got bored and stopped inspecting the underwater speaker making the sounds.
At this point, he played the whistles of the listening dolphins’ old friends.
When the dolphins heard these familiar whistles, they would perk up and approach the speakers, often whistling their own name and listening for a response.
Overall, the dolphins responded more to animals they’d known decades ago than to random animals—suggesting they recognized their former companions, according to the study, published recently in Proceedings of the Royal Society B.
Cheeky Dolphins
Working with animals as intelligent as dolphins was a challenge, Bruck added. The animals loved participating in the experiment so much that they’d often hover over the speaker, blocking the noise.
Others would begin “whistling directly at me as if I could understand them,” he said.
And one set of cheeky young dolphins swam up to Bruck and started whistling the names of the dominant males in their group in order of rank, perhaps suggesting the names they wanted to hear, Bruck said.
Memory Linked to Smarts?
Why dolphins—which live an average of 20 years in the wild—need long-term memory is still unknown. But it may have to do with maintaining relationships, since over time dolphin groups often break up and reorganize into new alliances.
This sort of social system is called “fission-fusion,” and it’s also seen in elephants and chimpanzees—two other highly intelligent and social beings.
Coincidence? Bruck suspects not: “It seems that maybe complex cognition comes from a place of trying to remember who your buddies are,” he said.

What Color is Your Night Light? It May Affect Your Mood
Study Finds Red Light Least Harmful, While Blue Light is Worst
When it comes to some of the health hazards of light at night, a new study suggests that the color of the light can make a big difference.
In a study involving hamsters, researchers found that blue light had the worst effects on mood-related measures, followed closely by white light.
But hamsters exposed to red light at night had significantly less evidence of depressive-like symptoms and changes in the brain linked to depression, compared to those that experienced blue or white light.
The only hamsters that fared better than those exposed to red light were those that had total darkness at night.
The findings may have important implications for humans, particularly those whose work on night shifts makes them susceptible to mood disorders, said Randy Nelson, co-author of the study and professor of neuroscience and psychology at The Ohio State University.
“Our findings suggest that if we could use red light when appropriate for night-shift workers, it may not have some of the negative effects on their health that white light does,” Nelson said.
The study appears in the Aug. 7, 2013, issue of The Journal of Neuroscience.
The research examined the role of specialized photosensitive cells in the retina — called ipRGCs — that don’t have a major role in vision, but detect light and send messages to a part of the brain that helps regulate the body’s circadian clock. This is the body’s master clock that helps determine when people feel sleepy and awake.
Other research suggests these light-sensitive cells also send messages to parts of the brain that play a role in mood and emotion.
“Light at night may result in parts of the brain regulating mood receiving signals during times of the day when they shouldn’t,” said co-author Tracy Bedrosian, a former graduate student at Ohio State who is now a postdoctoral researcher at the Salk Institute. “This may be why light at night seems to be linked to depression in some people.”
What people experience as different colors of light are actually lights of different wavelengths. The ipRGCs don’t appear to react to light of different wavelengths in the same way.
“These cells are most sensitive to blue wavelengths and least sensitive to red wavelengths,” Nelson said. “We wanted to see how exposure to these different color wavelengths affected the hamsters.”
In one experiment, the researchers exposed adult female Siberian hamsters to four weeks each of nighttime conditions with no light, dim red light, dim white light (similar to that found in normal light bulbs) or dim blue light.
They then did several tests with the hamsters that are used to check for depressive-like symptoms. For example, if the hamsters drink less-than-normal amounts of sugar water — a treat they normally enjoy — that is seen as evidence of a mood problem.
Results showed that hamsters that were kept in the dark at night drank the most sugar water, followed closely by those exposed to red light. Those that lived with dim white or blue light at night drank significantly less of the sugar water than the others.
After the testing, the researchers then examined the hippocampus regions of the brains of the hamsters.
Hamsters that spent the night in dim blue or white light had a significantly reduced density of dendritic spines compared to those that lived in total darkness or that were exposed to only red light. Dendritic spines are hairlike growths on brain cells that are used to send chemical messages from one cell to another.
A lowered density of these dendritic spines has been linked to depression, Nelson said.
“The behavior tests and changes in brain structure in hamsters both suggest that the color of lights may play a key role in mood,” he said.
“In nearly every measure we had, hamsters exposed to blue light were the worst off, followed by those exposed to white light,” he said. “While total darkness was best, red light was not nearly as bad as the other wavelengths we studied.”
Nelson and Bedrosian said they believe these results may be applicable to humans.
In addition to shift workers, others may benefit from limiting their light at night from computers, televisions and other electronic devices, they said. And, if light is needed, the color may matter.
“If you need a night light in the bathroom or bedroom, it may be better to have one that gives off red light rather than white light,” Bedrosian said.

A star (cell) is born
Astrocytes are star-shaped (the name derives from the Greek words for star and cell) glial cells. They are the most abundant cell type in the human brain, and for good reason: They have a lot of jobs, from providing biochemical support of the endothelial cells that form the blood-brain barrier to delivering nutrients to nervous system tissue to helping repair the spinal cord after traumatic injury.
Neurons attract most of the attention, but researchers are increasingly investigating the roles and potential of astrocytes in treating a host of neurological harms and diseases.
For example, a CIRM-supported “disease team” of scientists at UC San Diego School of Medicine and the Salk Institute for Biological Studies is investigating the possibility of transplanting healthy astrocytes derived from stem cells into patients suffering from amytrophic lateral sclerosis or Lou Gehrig’s disease. The work is based, in part, upon encouraging findings in an ALS mouse model, conducted by Don Cleveland, PhD, and colleagues.
More recently, UC Davis scientists underscored the potential therapeutic value of astrocytes, reporting in the journal Nature Communications that the cells’ “calm” nature may make them best suited for some future stem cell-based neurological therapies.
“Astrocytes are often considered just ‘housekeeping’ cells because of their supportive roles to neurons, but they’re actually much more sophisticated,” said study co-author Wenbin Deng in a news release.
“They are critical to several brain functions and are believed to protect neurons from injury and death. They are not excitable cells like neurons and are easier to harness. We wanted to explore their potential in treating neurological disorders, beginning with stroke.”
Of course, success is neither guaranteed nor looming, but if it happens, astrocytes will have a starring role.
