When David Linstead was about 9 or 10, he pestered his parents for a microscope.

It sparked a lifetime of scientific curiosity. David is now a retired research scientist with over 20 years of experience. In 2016, he captured an incredible slice of life in a microscopy photo that borders on fine art. The blue hues and fluorescent oranges and pinks burst through in a kaleidoscope of colors. To the uninformed eye, this image could be seen as evidence of alien life. But it's actually a photo of cat skin with hair and whiskers.

A polarized light micrograph of a section of cat skin, showing hairs, whiskers, and their blood supply. This sample is from a Victorian microscope slide. Blood vessels were injected with a red dye called carmine dye (here appearing black) in order to visualize the capillaries in the tissue, a newly developed technique at the time. This image is a composite made up of 44 individual images stitched together to produce a final image 12 millimeters wide. Image via David Linstead/Wellcome Image Awards.


The Wellcome Image Awards have been highlighting amazing images like this one for 20 years. This year's 22 finalists were chosen from photographs, illustrations, and other visual renderings from the sciences that showcase the beauty in their fields.

Here are 12 more images from this year's finalists that show the beauty behind science.

1. Hawaiian bobtail squid.

Native to the Pacific Ocean, Hawaiian bobtail squid are nocturnal predators that remain buried under the sand during the day and come out to hunt for shrimp near coral reefs at night. The squid have a light organ on their underside that houses a colony of glowing bacteria called Vibrio fischeri. The squid provide food and shelter for these bacteria in return for their bioluminescence.

2. Language pathways of the brain.

The brain is composed of two types of matter. Gray matter contains cells and is responsible for processing information. White matter connects these areas of grey matter, allowing information to be transferred between distant areas of the brain. Areas responsible for speech and language have been mapped to two different brain regions. This image shows a 3D-printed reconstruction of the white matter pathway connecting these two areas (here shown from the left), which is called the arcuate fasciculus.

3. Surface of a mouse retina.

The retina, located at the back of the eye, contains light-sensitive cells responsible for converting light into electrical nerve signals that the brain can process. As a result of aging or injury, the retina can lose this function, causing vision loss. This image was created by digitally stitching together over 400 images to form one large image, so as to show the entire surface of a mouse retina.

4. Vessels of a healthy mini-pig eye.

A 3D model of a healthy mini-pig eye. The dent on the right side of the image is the pupil, the opening that allows light into the eye. The blood vessels shown are bringing energy and food to the muscles surrounding the iris, which controls the amount of light entering the eye. The smallest vessels seen here are 20–30 micrometers (0.02–0.03 millimeters) in diameter. The other large vessels are feeder vessels for the retina, the light-sensing region at the back of the eye.

5. The placenta rainbow.

The placenta rainbow highlights differences in mouse placental development that can result from manipulation of the mother’s immune system. These placentas were investigated at day 12 of the 20-day gestation period — the point at which a mouse’s placenta has gained its characteristic shape but is still developing.

6. Developing spinal cord.

Our spines allow us to stand and move, and they protect the spinal cord, which connects all the nerves in our body with our brain. The spinal cord is formed from a structure called the neural tube, which develops during the first month of pregnancy.

This series of three images shows the open end of a mouse’s neural tube, with each image highlighting (in blue) one of the three main embryonic tissue types. On the left is the neural tube itself, which develops into the brain, spine, and nerves. On the right is the surface ectoderm — the word "ectoderm" comes from the Greek ektos meaning "outside" and derma meaning skin — which will eventually form the skin, teeth, and hair. The middle image shows the mesoderm (also from Greek, meaning "middle skin"), which will form the organs.

7. Zebrafish eye and neuromasts.

Image via Ingrid Lekk and Steve Wilson, University College London/Wellcome Image Awards.

This four-day-old zebrafish embryo has been modified using two mechanisms — borrowed from the fascinating worlds of bacteria and yeast — that are widely applied in genetics research. A DNA-editing technology called CRISPR/Cas9 was used to insert a gene called Gal4 next to the gene that the researchers wished to study. These Gal4 fish were then bred with special reporter fish to create fish where the gene of interest displays red whenever it is activated.

8. Intraocular lens "iris clip."

This image shows how an "iris clip," also known as an artificial intraocular lens, is fitted onto the eye. An iris clip is a small, thin lens made from silicone or acrylic material with plastic side supports to hold it in place. An iris clip is fixed to the iris through a three-millimeter surgical incision and is used to treat conditions such as myopia (nearsightedness) and cataracts (cloudiness of the lens). This particular patient, a 70-year-old man, regained almost full vision following his surgery.

9. #BreastCancer Twitter connections.

Image via Eric Clarke, Richard Arnett and Jane Burns, Royal College of Surgeons in Ireland/Wellcome Image Awards.

This is a graphical visualization of data extracted from tweets containing the hashtag #BreastCancer. Twitter users are represented by dots, called nodes, and lines connecting the nodes represent the relationships between the Twitter users. Nodes are sized differently according to the number and importance of other nodes they are connected with, and the thickness of each connecting line is determined by the number of times that a particular relationship is expressed within the data.

The "double yolk" structure at the top of the image indicates common mentions of two accounts. This area of the graph provides a graphical expression of trending data in Twitter, as it represents one tweet that was retweeted thousands of times.

10. Brain-on-a-chip.

Neural stem cells have the ability to form all the different cell types found in the nervous system. Here, researchers are investigating how neural stem cells grow on a synthetic gel called PEG. After just two weeks, the stem cells (magenta) produced nerve fibers (green). These fibers grew away from the cell due to chemical gradients in the gel, teaching researchers about how their environment affects their structural organization.

11. MicroRNA scaffold cancer therapy.

Researchers are investigating short genetic sequences called microRNAs, which control the proper function and growth of cells, as a possible cancer therapy. However, their potential use is limited by the lack of an efficient system to deliver these microRNAs specifically to cancerous cells. Researchers at the Massachusetts Institute of Technology have developed such a system, combining two microRNAs with a synthetic polymer to form a stable woven structure that is a bit like a net. This synthetic net can coat a tumor and deliver the two microRNAs locally to cancer cells.

12. Unravelled DNA in a human lung cell.

Image via Ezequiel Miron, University of Oxford/Wellcome Image Awards.

In order for plants and animals to grow and remain healthy, cells need to have the ability to replicate. During cell division, also known as mitosis, the entire DNA content of the cell is copied, with half going to each new cell. DNA is found in the nucleus, which acts a bit like the brain.

This picture shows the nucleus of one of two new daughter cells. The DNA in this cell has somehow become caught and is being pulled between the two cells. This has caused the DNA to unfold inside the nucleus, and DNA fibers can be seen running through it. As the new cells have moved apart, the tension distributed by the rope-like DNA has deformed the nucleus’ usually circular envelope.

There they are, in all their majesty.

Looking at the sheer brilliance of these images, it's easy to see why funding for science is fundamentally important to society. They show the value of science to better understand our world by revealing the quiet beauty behind the universe's veil. That's the power of scientific exploration.

We can all be part of the giving movement

True

We all know that small acts of kindness can turn into something big, but does that apply to something as small as a pair of socks?

Yes, it turns out. More than you might think.

A fresh pair of socks is a simple comfort easily taken for granted for most, but for individuals experiencing homelessness—they are a rare commodity. Currently, more than 500,000 people in the U.S. are experiencing homelessness on any given night. Being unstably housed—whether that’s couch surfing, living on the streets, or somewhere in between—often means rarely taking your shoes off, walking for most if not all of the day, and having little access to laundry facilities. And since shelters are not able to provide pre-worn socks due to hygienic reasons, that very basic need is still not met, even if some help is provided. That’s why socks are the #1 most requested clothing item in shelters.

homelessness, bombasSocks are a simple comfort not everyone has access to

When the founders of Bombas, Dave Heath and Randy Goldberg, discovered this problem, they decided to be part of the solution. Using a One Purchased = One Donated business model, Bombas helps provide not only durable, high-quality socks, but also t-shirts and underwear (the top three most requested clothing items in shelters) to those in need nationwide. These meticulously designed donation products include added features intended to offer comfort, quality, and dignity to those experiencing homelessness.

Over the years, Bombas' mission has grown into an enormous movement, with more than 75 million items donated to date and a focus on providing support and visibility to the organizations and people that empower these donations. These are the incredible individuals who are doing the hard work to support those experiencing —or at risk of—homelessness in their communities every day.

Folks like Shirley Raines, creator of Beauty 2 The Streetz. Every Saturday, Raines and her team help those experiencing homelessness on Skid Row in Los Angeles “feel human” with free makeovers, haircuts, food, gift bags and (thanks to Bombas) fresh socks. 500 pairs, every week.

Or Director of Step Forward David Pinson in Cincinnati, Ohio, who offers Bombas donations to those trying to recover from addiction. Launched in 2009, the Step Forward program encourages participation in community walking/running events in order to build confidence and discipline—two major keys to successful rehabilitation. For each marathon, runners are outfitted with special shirts, shoes—and yes, socks—to help make their goals more achievable.

Help even reaches the Front Street Clinic of Juneau, Alaska, where Casey Ploof, APRN, and David Norris, RN give out free healthcare to those experiencing homelessness. Because it rains nearly 200 days a year there, it can be very common for people to get trench foot—a very serious condition that, when left untreated, can require amputation. Casey and Dave can help treat trench foot, but without fresh, clean socks, the condition returns. Luckily, their supply is abundant thanks to Bombas. As Casey shared, “people will walk across town and then walk from the valley just to come here to get more socks.”

The Bombas Impact Report provides details on Bombas’s mission and is full of similar inspiring stories that show how the biggest acts of kindness can come from even the smallest packages. Since its inception in 2013, the company has built a network of over 3,500 Giving Partners in all 50 states, including shelters, nonprofits and community organizations dedicated to supporting our neighbors who are experiencing- or at risk- of homelessness.

Their success has proven that, yes, a simple pair of socks can be a helping hand, an important conversation starter and a link to humanity.

The show must go on… and more power to her.

There are few things that feel more awful than being stranded at the altar by your spouse-to-be. That’s why people are cheering on Kayley Stead, 27, from the U.K. for turning a day of extreme disappointment into a party for her friends, family and most importantly, herself.

According to a report in The Metro, on Thursday, September 15, Stead woke up in an Airbnb with her bridemaids, having no idea that her fiance, Kallum Norton, 24, had run off early that morning. The word got to Stead’s bridesmaids at around 7 a.m. the day of the wedding.

“[A groomsman] called one of the maids of honor to explain that the groom had ‘gone.’ We were told he had left the caravan they were staying at in Oxwich Bay (the venue) at 12:30 a.m. to visit his family, who were staying in another caravan nearby and hadn’t returned. When they woke in the morning, he was not there and his car had gone,” Jordie Cullen wrote on a GoFundMe page.

As people mourn the death of Coolio, a video resurfaced showing just how cool he was

Not many college kids get to say Coolio performed 'Gangsta's Paradise' in their dorm room.

As people mourn the death of Coolio, resurfaced video show how cool he was.

There aren't too many people who haven't heard the song "Gangsta's Paradise" by Coolio. It quickly climbed the charts after it was used in the soundtrack of the movie "Dangerous Minds" and brings nostalgia anytime it comes on the radio. Following Coolio's unexpected death, it's no wonder the song is being played again. But one user had a unique experience with the late rapper, and his 2013 video has resurfaced on YouTube showing Coolio hanging out with the group of England's University of Central Lancashire students in their dorm room.

Dr. Daniel Mansfield and his team at the University of New South Wales in Australia have just made an incredible discovery. While studying a 3,700-year-old tablet from the ancient civilization of Babylon, they found evidence that the Babylonians were doing something astounding: trigonometry!

Most historians have credited the Greeks with creating the study of triangles' sides and angles, but this tablet presents indisputable evidence that the Babylonians were using the technique 1,500 years before the Greeks ever were.
