Every Thursday morning we dive into new and future Science trends that will change the world. Future medical procedures, to new advanced technologies and out into space. If you love science, technology and facts, then this is the show for you!
New findings strongly suggest that COVID-19 may negatively affect sperm quality and reduce fertility in men, according to research published in the Journal Reproduction. The study indicates that COVID-19 infection can cause increased sperm cell death, inflammation, and oxidative stress, resulting in lower sperm quality and potentially reducing fertility.
General Motors, in partnership with Navistar, says it will focus on fuel cells for long haul trucks. According to reports, they will include a tie-in with a company called OneH2 to produce hydrogen and control the storage, delivery, and designing systems.
Apparently, Apple quietly added a new iMessage security feature in iOS 14 called BlastDoor. BlastDoor is a new sandbox inside iMessage that receives and sanitizes all iMessage content before it’s shown to the user.
The term "3D printing" can refer to a variety of processes in which material is deposited, joined, or solidified under computer control to create a three-dimensional object, with the material being added together (such as liquids or powder grains being fused together), typically layer by layer.
Today we are discussing teeth. Our ancestors had much bigger jaws than we do, which helped them chew a tough diet of roots, nuts, and leaves. And what meat they ate, they tore apart with their teeth, all of which led to worn-down chompers that needed replacing.
Today is Thursday, February 4, 2021. At the top of our news, a new laser system to aid in cancer treatment will help surgeons remove cells without damaging healthy tissue. Scientists proved in the lab that the laser system could remove cancer cells in a way that does not damage the surrounding, healthy cells. Those healthy cells were within the width of a human hair.....
An African clawed frog, in biology, it is known as Xenopus laevis. This frog typically lives in sub-Saharan Africa's streams and ponds, scavenging for food that it rips apart with its feet. In January, researchers at the University of Vermont and Tufts University published a report that gave the amphibian a different lot in life. They harvested its embryonic skin and heart cells and reassembled the living matter into robotic devices — transforming Xenopus into xenobot. Xenobots are the first robots made entirely of living materials....
If Thwaites melts away, that much-larger ice block will add water to our oceans as well, further driving up sea level rise. If and when this might happen, however, is what researchers are trying to learn. Scientists know that Thwaites Glacier is very important, but still, how much and how fast sea levels increase into the decades and centuries is still uncertain....
I’ve heard that the blue waters near ocean glaciers are beautiful to behold. The same could be said about blue eyes. New research shows that people with blue eyes have a single, common ancestor. A team at the University of Copenhagen have tracked down a genetic mutation that took place 6-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today....
NASA's Mars 2020 Perseverance rover mission is just 22 days from landing on the surface of Mars. The spacecraft has about 25.6 million miles remaining in its 292.5-million-mile journey and is currently closing that distance at 1.6 miles per second....
When we think of human evolution, our minds wander back to the millions of years it took natural selection to produce modern-day man. Recent research suggests that humans continue to evolve....

We discuss this week's hot science topics.
Today is September 10th, 2020. The first use of prosthetics goes back to the fifth Egyptian Dynasty that ruled between 2750 to 2625 BC. The earliest known written reference to an artificial limb was made around 500 BC. Thousands of changes in technology changed the artificial limb over time, now researchers have created an artificial skin that is capable of reacting to pain just like human skin.
According to a leaked FBI bulletin, cops are worried that criminals are using internet-connected smart doorbells, such as Amazon’s Ring doorbells, to spy on law enforcement.
For the first time, engineers built optical tweezers capable of grabbing individual bio-molecules and proteins without damaging them — this is a vast improvement to technology.
Amazon Prime Air, the retail giant’s drone delivery project, was just designated an “air carrier” by the Federal Aviation Administration, meaning they can start to test drone package deliveries.
Using carefully-crafted nanomaterials, Tokyo University of Agriculture and Technology scientists were able to bend light in a way no natural material could accomplish. The result? The first hologram movie of the Earth spinning on its axis.
In another breakthrough, a team of French scientists created an anti-gravity levitating fluid that allows a tiny boat to float on the top and bottom of the fluid. it, like flipping gravity on its head.
Scientists recently found a new victim of climate change and pollution: The blackmouth catshark that had its teeth, skin, and other features dissolved away from swimming in contaminated water.

Today, August 27th, 2020. Here is something interesting that happened earlier this month. NASA released it’s finding from a trip to the dwarf planet Ceres on August 10th.
Earlier this month, researches discovered something frightening. Many patients that had COVID-19 exhibit neurological symptoms, from loss of smell to delirium to a higher risk of stroke. They are worried that COVID-19 survivors may face a wave of cog na tive issues.
NASA is soon going to start building its latest spacecraft called Psyc-he. The NASA mission will be to a 70 mile-wide asteroid named ‘16 Psyc-he’. The spacecraft cleared the ‘critical design’ phase last month.
A team of Chinese scientists just improved the way they can send a quantum-encrypted message, managing to beam one all-the-way down from a satellite. That twisted a lot of cybersecurity heads around the world.
According to MIT mechanical engineer Mr. Henry, humans are running out of time to stop our own extinction. The challenge comes down to physics: Almost all of our energy consumption involves generating or transferring heat. Coupled with the greenhouse gas emissions that come with that energy use, Henry warns that we are very near the point of no return that would send us on a path toward inevitable destruction of the climate and ourselves.
In an unusual experiment, scientists got to watch as bacteria adapted to a new host, evolving to become more infectious over hundreds of generations. While tracking changes over time, the University of Vienna scientists saw two very different evolutionary strategies emerge in bacteria that were subjected to different conditions. The research, published in the journal PNAS, is a fascinating case study that helps scientists understand how bacteria become dangerous.

The new plane just announced the SR-72 would fly twice as fast—so fast that at top speed, the very air entering its engines will be moving as fast as an SR-71. Keeping combustion and thrust going under such conditions is like lighting a cigar in a hurricane. The SR-72’s planned ability to go from a standing start to Mach 6 and back again is a hat trick no one has been able to pull off. Mach 6 is 3,600 miles per hour.
In the beginning, there was Adam. We’re not talking about the supernatural alleged first human, but rather the first machine to fully automate the scientific process and make a discovery on its own. Adam looks nothing like a human. It resembles a big box about the size of an office cubicle. It’s equipped with robotic arms, incubators, a freezer, cameras, and other parts to help it do work. Everything it needs to conduct its research is there, including a brain.
California-based tech company Hyperion has unveiled the Hyperion XP-1, a hydrogen fuel cell-powered hypercar with an advertised 1,000-mile range and a top speed of 221 mph. It can launch from 0 to 60 mph in just 2.2 seconds.

What makes ants so fascinating today is their effectiveness at preventing epidemics within their colonies, despite their close living quarters and massive communities. In fact, epidemics and sick colonies are rarely, if ever, found in the wild. Thanks in part to this, ants are one of the most successful species on Earth. According to some estimates, they make up almost a quarter of all terrestrial animal biomass. And because of the social measures they’ve evolved to use, ant behavior often seems distinctly intelligent. As human communities are warding off this generation’s biggest pandemic to date, we should take a closer look at how our fellow inhabitants deal with infectious outbreaks. Scientists have observed many species of ants disease-curbing social practices, including separating groups by role within their nest, sanitizing themselves and their living quarters, and mixing tree resin with their poison to kill pathogenic spores.

In 2007, astronomers digging through data from six years prior found a very strong, very brief burst of radio emission coming from an unidentified source in space. It introduced us to a new class of objects dubbed fast radio bursts or FRBs for short. “Fast” because these blips are very short—less than five milliseconds in duration. The “radio” portion of the nickname is because the emission is detected by radio telescopes surveying the sky at radio wavelengths. They are called “bursts” because the signals disappear as quickly as they appeared, without warning and, so far, without explanation. Since 2007, astronomers have added 17 more bursts to the list of known FRBs. However, their origins are still a bit of a mystery because of their defining characteristics, the very reasons they are so interesting, also make them challenging to study.

Last month engineers started construction of the world’s largest nuclear fusion project in southern France, with operations planned to begin in late 2025. The project, called ITER, is an international collaborative effort between 35 countries with enormous ambitions: prove the feasibility of fusion energy with a gigantic magnetic device called a “tokamak,” as per the project’s official website. Enabling the exclusive use of clean energy will be a miracle for our planet. Fusion power, in theory, works by harnessing the energy released by two lighter atomic nuclei fusing to form a heavier nucleus, and turning it into electricity.
We see batteries almost every day, but our brain hardly registers them unless we need one. On average, we throw away over 179,000 batteries every year, plus an additional 140,000 rechargeable batteries. We all know these small reactors create electricity, but what you may not know is the earliest known battery, called the “Baghdad Battery” is from 250BC. It was re-discovered in 1938 in the basement of the Baghdad museum. Controversy surrounds this earliest example of a battery, but suggested uses include electroplating, pain relief, or a religious tingle.
American scientist and inventor Benjamin Franklin first used the term "battery" in 1749 when he was doing experiments with electricity using a set of linked capacitors. The first true battery was invented by the Italian physicist Alessandro Volta in 1800. Volta stacked discs of copper and zinc separated by a cloth soaked in salty water. Wires connected to either end of the stack produced a continuously stable current.

Now, get ready for the extreme advancement of x-ray technology. A brilliant new light shines in France, where officials at the ESRF announced the reopening of their completely rebuilt x-ray source. The ring-shaped machine, 844 meters around or 2,769-foot circle, generates x-ray beams 100 times brighter than its predecessor and 10 trillion times brighter than medical x-rays. The intense radiation could open up new vistas in x-ray science, such as imaging whole organs in three dimensions.

One of the biggest challenges facing crewed missions to Mars is figuring out how to protect crewmembers from the onslaught of deadly cosmic rays. Now, scientists at a number of universities say there’s growing evidence that an unusual solution could be effective: building shields out of a radiation-absorbing fungus that grows near the Chernobyl Nuclear Power Plant.

Humans Horrorfying Use of Radium
Just about everyone in the world will see an image of a double helix and immediately identify it as DNA. This molecule is two polynucleotide chains that carry the genetic blueprint that makes it possible for organisms and viruses to grow and reproduce. Each cell uses the information in DNA as a guidebook to create the proteins needed for life; it also acts like a police officer to help direct the behavior of cells.
Nothing is perfect, not even DNA. Sometimes a mistake happens during replication. Sometimes the error can cause diseases or even death. Other times it may lead to an evolutionary shift in an organism. One way DNA can be damaged is when an organism is subjected to radiation exposure. Radiation can break the bonds between atoms or ionize water molecules and form free radicals. Radiation damage to DNA can change the proteins produced by cells, modifying cell behavior, and may lead to diseases such as cancer. Different forms of radiation cause different mutations in cells.

Every Human Contains Radiation
A by-product of nuclear explosions is the production of carbon-14. When carbon-14 joins the atmosphere, it enters the food chain and gets bound up in the cells of living organisms. There was so much carbon-14 released into the atmosphere that researchers in 2020 can still detect it in the DNA of humans born today. That’s right; it is inside of you right now. How unsettling is that?

Eyeballs with Teeth
Whale sharks are gentle, giants that swim in tropical seas and scoop up plankton. They also have a sharp eye. According to new research, tiny teeth cover their eyes.
Whale sharks, along with some other shark species, have dermal denticles that cover their bodies like scales. Dermal Denticles are shaped like the letter V (as in Victory). The unique shape decreases the drag and turbulence of water, allowing them to swim faster. It also acts as an armor against other sea creatures that might bite them.

After decades of development, the James Webb Space Telescope finally completed the final systems tests! The telescope is the "largest and most technically complex space science telescope NASA has ever built." It's an international collaboration between NASA, the European Space Agency, and the Canadian Space Agency. Development of the delay-plagued orbital spyglass began in 1996, with an initial launch planned in 2007. Now, after a slew of significant redesigns, countless delays, and budget overruns, NASA is tentatively eyeing a March 2021 launch. The space agency will reevaluate launch readiness later this month.
In a biological beating of swords into plowshares, researchers have converted a bacterial toxin into a genome editing tool that can make precise changes to DNA in mitochondria. Mitochondria are specialized structures unique to the cells of animals, plants and fungi. They serve as batteries, powering various functions of the cell and the organism as a whole. Though mitochondria are an integral part of the cell, evidence shows that they evolved from primitive bacteria.
The first cataract surgery was described in a textbook written by an Indian physician who lived on the banks of the Ganges river around 1000 BC. The method he used was called "couching" and consisted of using a needle or a thorn to push the clouded lens downwards into the eye. The stick was used as a tool to displace the clouded white cataract to clear the visual axis. Once the patient claimed that he or she could see clearly, the couching stopped. The method had abysmal results with only about a 30% success rate. Today couching is still performed in some remote areas of the third world. The cataract is not actually removed from the eye, but dislodged so that the visual axis is clear.
Woodpeckers are fascinating birds. This time of the year, when Craig and I are on our morning walk, we hear the unmistakable sound of a woodpecker pecking at a tree or telephone pole. Most of the time, we can spot them clinging to the side of a tree, sometimes sideways or upside down. Then they peck the tree, and we wonder how they don’t get a headache.
Vaccines contain the same germs that cause disease. For example, the measles vaccine contains the measles virus, and the Hib vaccine contains Hib bacteria. But they have been either killed or weakened to the point that they don’t make you sick. Some vaccines contain only a part of the disease germ. A vaccine stimulates your immune system to produce antibodies, exactly like it would when exposed to the disease. After getting vaccinated, you develop immunity to that disease, without having to get the disease first.
The knee is the largest joint in the body, and having healthy knees is required to perform most everyday activities. The knee is made up of the lower end of the thighbone, the upper end of the shinbone, and the kneecap. The ends of these three bones are covered with cartilage, a smooth substance that protects the bones and enables them to move easily within the joint.
Mars is the fourth planet from the sun. Because of the Red Planets’ bloody color, the Romans named it after their god of war. In truth, the Romans copied the ancient Greeks, who also named the planet after their god of war, Ares. Other civilizations also typically gave the planet names based on its color, the Egyptians called it “Her De-sher,” meaning “the red one,” while ancient Chinese astronomers dubbed it “the fire star.”
An ultrasound scan uses high-frequency sound waves to create images of the inside of the body. It is suitable for use during pregnancy. Ultrasound scans, or sonography, are safe because they use sound waves or echoes to make an image, instead of radiation. Doctors use Ultrasound scans to evaluate fetal development, and they can detect problems in the liver, heart, kidney, or abdomen. They may also assist in performing certain types of biopsy. The image produced is called a sonogram.
The search for the secret to a long life began, in part, with 560 unique strains of baker’s yeast. Matt Kaeberlein noticed that some of the strains with the greatest longevity tended to divide in slow motion. And he found that this slowdown, which takes place in the molecular mechanisms controlling cell division, could be tinkered with artificially by feeding the yeast a drug called rapamycin.
It's Raining Plastic:
Since the dawn of history, humankind has struggled to develop materials offering benefits not found in natural materials. The development of plastics started with the use of natural materials that had fundamental plastic properties, such as shellac and chewing gum. The next step in the evolution of plastics involved the chemical modification of natural materials such as rubber, nitrocellulose, and collagen. Finally, the full range of entirely synthetic materials that we would recognize as modern plastics started around 100 years ago.............
Scientists Are Making Fuel From Sunlight and Air
Few activities swell our carbon footprint quite like flying. A one-hour flight on a twin-engine jet aircraft burns almost 6,000 pounds of kerosene and adds nearly 19,000 pounds of carbon dioxide to the atmosphere. The environmental impact of air travel is stark, but what if flying could be made zero carbon?
Hunt for Alien “Technological Civilizations”
A team of astronomers from Harvard and other institutions are collaborating on a new project to scan the skies for technological signatures from alien civilizations. It’s a noteworthy new project, as it’s the first to receive a NASA grant for SETI-specific research in more than 30 years.
Earth’s Magnetic Field: Magnetic fields around planets behave in the same way as a bar magnet. But at high temperatures, metals lose their magnetic properties. This fact makes it clear that Earth’s hot iron core isn’t what creates the magnetic field around our planet. Instead, a dynamo effect is what creates Earth’s magnetic field. To understand what a dynamo effect is, think of a bicycle light. Magnets in the dynamo, or generator, start spinning when a person pedals, which creates an electric current. The electricity generated powers the bicycle’s light. This process also works in reverse. If you have a rotating electric current, it will create a magnetic field.
Human Hibernation: The dream of suspended animation has long captivated the human imagination, reflected in countless works of mythology and fiction, from King Arthur and Sleeping Beauty to Captain America and Han Solo. By effectively pausing time itself for an individual, a state of stasis promises to enable the repair of lethal injuries, prolong life and allow for travel to distant stars.
Dads Experience Postpartum Depression: In the U.S., 1 in 7 fathers suffers from depression during the time of pregnancy and a child’s infancy. That number skyrockets to 1 in 4 men after birth around the three to six month period. If the mother experiences postpartum depression, 1 in 2 dads will also experience postpartum depression. Also, up to one-quarter of expecting fathers experience anxiety during pregnancy, and more than half have anxiety during their child’s infancy. These are worrisome statistics since research shows a strong correlation between anxiety and depression.
We live on a green planet. Today we may take plants for granted, but they are the most important living things on Earth. Their establishment onto land made it possible for all animal life to survive, from the smallest ants to the biggest dinosaurs. Humans and a few other animals make up the short category of omnivores. The best evidence of this is our teeth: we have biting/tearing/ripping incisors and canines (like carnivores) and chewing molars (like herbivores). Animals with such diverse teeth tend to be omnivores.
There are about 2,700 different species of mosquitos in the world. The United States is home to about 150 different species. For centuries mosquitoes have plagued people all over the globe, and eventually, humanity found out that these pests also carried deadly diseases.
In a sad sideshow to the COVID-19 pandemic, authorities in the Netherlands began to gas tens of thousands of mink on 6 June, most of them pups born only weeks ago. SARS-CoV-2 has attacked farms that raise the animals for fur, and the Dutch government worries infected mink could become a viral reservoir that could cause new outbreaks in humans.
Since the very first humans roamed the Earth about 300,000 years ago, the tidal-locked face of the Moon silently watched all of humanity unfold. She has been the one single object that every living creature could see no matter where they were on planet Earth. She was there for every war, every natural disaster, every achievement. Hundreds of millions of people at one time or another have gazed at her in wonder.
Sea-level rise is a real problem. Observational data and changing conditions in such places as Greenland suggest if there is a problem there, then it is an underestimation of future sea-level rise elsewhere. The IPCC reports offer conservative projections of sea-level increase based on assumptions about the future behavior of ice sheets and glaciers, leading to estimates of sea level roughly following a linear upward trend mimicking that of recent decades.
Need an endless boost to your immune system? Growing culinary herbs on your balcony, backyard, or even your windowsill can be a great way to incorporate them into your cooking creations. There’s an added bonus: many herbs are beneficial to the immune system. Using these flavorful and aromatic herbs can give an extra oomph to a meal, as well as your health.

US Military Kill an Aircraft With an Energy Weapon
The idea of using light as a weapon can be traced back to Hippocrates, commander of the Greek forces in 212 B.C. His forces supposedly set fire to the sails of the Roman fleet by focusing sunlight with mirrors. Weapons systems based on lasers and ray guns, long a staple of science fiction, have captured the imagination of people everywhere.
Earth’s Rare Elements Are Running Out!
Let’s do a small thought experiment. Close your eyes a picture the condiment section in your local supermarket, specifically at the ketchup bottles. How many are on the shelf, two or three dozen? Most likely those bottles are replaced with new ones either weekly or bi-weekly. Now let’s look at just the Heinz Ketchup. Heinz Ketchup makes 650 million bottles each year. An estimated 1,000 bottles per minute.
There’s a Russian Volcano That Erupts Diamonds
Diamonds are remarkable, they formed over 3 billion years ago deep within the Earth's crust under conditions of intense heat and pressure that cause carbon atoms to crystallize, thus creating diamonds. They are brought to the surface in powerful explosive volcanic eruptions.
The octopus was a Graneledone boreopacifica, a species of octopus that we know very little about. But the scientists were not there for her, after making a note of what they saw they moved onto business. The team went back a month later and found the same octopus on a rock sitting on 160 eggs.
The human eye is a complex organ. Scientists have enough theoretical evidence to suggest the first eye-like structure was a light-sensitive pigmented spot on the skin. Through natural selection, this first eye has gone through changes to form the human eye we know today.
NASA is looking for participants to spend eight months together inside a spaceflight simulator at the Russian Institute for Biomedical Problems in Moscow.
Today is Thursday, May 21st, 2020. If we were in a spaceship and approached Earth from the North pole in the summer, we would see a roughly circular mass of blue water dotted with ice, and almost encircled by landmasses. Some reflecting in a brilliant white from ice and snow, but mostly the landmasses are brown and green. What we cannot see from space is what lays just beneath the surface. It is the subsection of the Earth, we are discussing today.
A genetic Chimera is a single organism composed of cells with more than one distinct genotype. To produce a Chimera animal, scientists need to merge multiple fertilized eggs. If you are not quite sure what a Chimera is, let’s take a quick look into mythology. The centaur: chest and arms of a man attached to a horse. Or the three-headed hound of hell. The best example may be Medusa, the body of a woman merged with serpents. You get the idea.
Georgia’s Department of Natural Resources is warning residents that an invasive species of giant lizards has established in the state, posing a threat to wildlife and crops because they eat “anything they want.”
Today is Thursday, May 14th, 2020. The bond between dogs and humans can be traced back to about 15,000 years ago. These lovable and loyal animals have found their way into 48% of American households. For centuries canines have been listed as man’s best friend.
Neuralink is a device that will first be used to help paraplegics with simple tasks such as using an iPhone and making mouse clicks on a computer — by making no physical movement.
The Asian giant hornet can kill humans with its stings. It also decapitates bees methodically. Then they rip out the bee’s chest, which they bring back to their hive to feed their young. The hornets leave the honeybee hives vacant, all that remains is the honey.
Today is Thursday, May 7, 2020. When it comes to heart attack risk, how do you score? If you want a sneak peek into your risk of heart disease, here are your options: Your doctor can measure cholesterol and blood pressure, ask about your history of smoking and diabetes, and consider age and gender. For the 50-plus crowd, this approach works well, but these traditional risk factors do not account for heart attacks in those who are younger. Soon this may all change; scientists have an idea, based on your genes.
Each year thousands of patients face life-long losses in sensation and motor function from spinal cord injury and related conditions in which axons are badly damaged or severed. New research in mice shows, however, that gains in functional recovery from these injuries may be possible, thanks to a molecule known as Lin28, which regulates cell growth.
This week we can’t stop talking about Elon Musk saying the star link network will go live in six months.
Today is Thursday, April 30, 2020. How many times, especially lately, have you heard that copper kills viruses. Can this be true, or is it just another snake oil cure? The SARS-CoV-2 virus endures for days on plastic or metal but disintegrates soon after landing on copper surfaces. Let’s discuss why.
scientists made rice genetically engineered to resist heat waves, and can also produce up to 20% more grain.
