As humans, we have many senses through which we can experience and explore the world: sight, sound, taste, hearing, and smell. Which one do you rely upon most? If “sight” is your answer, you have something in common with the rest of the world.
Because humans are visual creatures, it can be hard for some to reflect on the past and imagine what life must have been like even a few decades ago. Fortunately, emerging technology is helping with this conundrum. Professional colorist from Brazil, Marina Amaral, recently recolored a series of old photos. To say the result is breathtaking is an understatement.
As Bored Panda reports, Amaral is a Photoshop enthusiast and a history buff. Recoloring photos is a way she can merge both interests. In 2015, Amaral was scrolling through a history forum on the internet when she came across colorized photos of WWI. Inspired by the images, Amaral began adding color to old black and white photos. Most importantly, she does extensive research on the images to ensure every detail is as realistic as possible.
The recolored images allow people to experience and reflect on the past in a new way. Said Amaral, “Each photo is made to be realistic by recognizing the value behind each one of them, respecting and preserving their stories, paying attention to the finer details and maintaining their original essence.”
“Every completed work has gone through long and in-depth research, and is supported by the opinions of experts in each particular area if necessary, to faithfully reproduce the original colors and atmosphere,” she added. “My work ranges from simple portraits to complex and detailed images, taken from various historical periods covering a wide range of topics.”
Following are 10+ examples of Amaral’s work:
1) Ruby Bridges, Escorted By US Marshals To Attend An All-White School, 1960
2) Cree Man, Maple Creek, Saskatchewan, Canada, 1903
4) A Photographer Uses His Own Backdrop To Mask Poland’s World War II Ruins While Shooting A Portrait In Warsaw In November 1946
5) Lewis Powell, a Conspirator With John Wilkes Booth (Who Assassinated President Abraham Lincoln)
6) Four Female Pilots Leaving Their Ship, Pistol Packin’ Mama, At The Four Engine School At Lockbourne AAF, 1944
7) Marie Sklodowska Curie
8) Queen Elizabeth II
9) Banana Docks, New York. CA 1890 – 1910

Scientists Create First-Ever Embryos With Monkey and Human Cells
For the first time, scientists have created embryos in a lab that contain the cells of both humans and monkeys.
Scientists hope that by creating chimeric embryos – embryos containing cells from two distinct species – they might be able to create organs for people who desperately need transplants.
Over 100,000 people in the United States lone are currently on a waiting list for organ transplants crucial to saving their lives, but the supply of donor organs has dropped significantly since the pandemic began unfolding.
Researchers have attempted to inject human stem cells into the embryos of pigs and sheep in recent years in hopes of growing organs for transplants, but this hasn’t yielded positive results. Scientists are hoping that by turning to macaque monkeys, which share a greater genetic similarity to humans, they may have more success.
In a study published Thursday in the journal Cell, researchers in the U.S. and China injected 25 pluripotent stem cells from humans into embryos from macaque monkeys.
After one day, the researchers detected human cells beginning to grow in 132 of the embryos. They embryos ultimately survived for 19 days.
However, bioethicists have raised concerns about the potential for abusing medical regulations that currently govern the treatment of animal and human subjects, as well as the possibility that a rogue scientists might potentially spike living creatures with human cells.
“My first question is: Why?” Kirstin Matthews, a science and technology fellow at Rice University’s Baker Institute, told NPR. “I think the public is going to be concerned, and I am as well, that we’re just kind of pushing forward with science without having a proper conversation about what we should or should not do.”
Researchers insist that the study serves purely humanitarian goals that could save countless lives in the future.
“This work is an important step that provides very compelling evidence that someday when we understand fully what the process is we could make them develop into a heart or a kidney or lungs,” said University of Michigan professor Jeffrey Platt, who was not involved in the study.
In Major First, New System Lets Paralyzed Users Control Tablet Computer Wirelessly
In what could be a major breakthrough for people suffering paralysis and other permanent disabilities, the first wireless command to a computer has been demonstrated.
According to a new study published in IEEE Transactions on Biomedical Engineering, scientists at Brown University say that the new system called BrainGate can transmit brain signals at “single-neuron resolution and in full broadband fidelity.”
BrainGate clinical trial participants with paralysis used a small transmitter connected to a person’s brain motor cortex to manipulate the interface of a tablet computer.
Participants were able to achieve the same typing speeds and point-and-click accuracy on the BrainGate system as they could with wired systems.
“We’ve demonstrated that this wireless system is functionally equivalent to the wired systems that have been the gold standard,” said John Simeral, an assistant professor of engineering at Brown University.
“The signals are recorded and transmitted with appropriately similar fidelity, which means we can use the same decoding algorithms we used with wired equipment,” Simeral said.

“The only difference is that people no longer need to be physically tethered to our equipment, which opens up new possibilities in terms of how the system can be used,” he added.
Neural interface technologies have attracted such high-profile figures as Elon Musk and social media titan Facebook in recent years.
“With this system, we’re able to look at brain activity, at home, over long periods in a way that was nearly impossible before,” said Brown University engineering professor and clinical trial leader Leigh Hochberg.
“This will help us to design decoding algorithms that provide for the seamless, intuitive, reliable restoration of communication and mobility for people with paralysis,” Hochberg added.
Scientists Discover X-Rays Coming From Uranus For Very First Time
Scientists are seeing X-rays being emitted from Uranus for the very first time, according to new research.
On Wednesday, the study was published in the Journal of Geophysical Research that lays out how a comparison of two images of the planet taken by the Chandra Observatory in 2002 and 2017 show a clear detection of X-rays in the first image, while the second shows a possible flare of X-rays on the enigmatic and icy planet.
According to NASA, the reason for these X-rays is “mainly the sun.”
However, “there are tantalizing hints that at least one other source of X-rays is present,” the space agency noted.
“One possibility is that the rings of Uranus are producing X-rays themselves, which is the case for Saturn’s rings,” NASA said. “Another possibility is that at least some of the X-rays come from auroras on Uranus, a phenomenon that has previously been observed on this planet at other wavelengths.”
X-rays can be provide a crucial window into the processes and characteristics of our universe. In the case of Uranus, these characteristics can include “atmospheric, surface and planetary ring composition.”
And while X-ray lights given off by the sun have been previously observed by astronomers on Jupiter and Saturn, this hasn’t been the case for icy giants like Uranus and Neptune.
The agency hopes that by figuring out the origin of the X-rays observed at Uranus, researchers can better grasp how mysterious objects including black holes and neutron stars emit X-rays.
Uranus is roughly four times the diameter of Earth and is the seventh planet from the sun, and is known for its distinct pair of rings around its equator and its unique side rotation.
