The Latest Scientific Breakthroughs and What They Mean to Us

Discovery of Lena horse

A group of scientists from the Mammoth Museum at the North-Eastern Federal University in Yakutsk, Russia has discovered and excavated a 42,000-year-old foal preserved in Siberian permafrost. The Lena horse (Equus caballus lenensis) foal may have lived in the Paleolithic period for only two months before possibly drowning in mud and dying. Its carcass contains the oldest liquid blood on record. Usually, blood evaporates and may turn into powder despite the icy permafrost. Other than its liquid blood, the urine, gut contents, and organs of the carcass have been well-preserved and are now under study along with the samples of permafrost where the foal had been found. This group of scientists is also responsible in studying an excavated body of mammoth with the goal of cloning it by using its DNA. With this new discovery, they are also looking into possibly cloning and reviving the foal. If these scientists become successful in cloning these ice age creatures, then it will not be a far cry from reality that us humans may also be able to clone and revive dead people or that we ourselves may be cloned after we are long gone (kind of like the Be Right Back episode of Netflix’s Black Mirror).

Dead Pigs’ Brain Cell Activity Restoration

According to a study published in the journal Nature, scientists from Yale School of Medicine in New Haven, Connecticut were able to restore circulation and cell activity in the brains of dead pigs, hours after they were slaughtered. The discovery is contradictory to what we know about brain activity after death, in which brain cells die in a short span of time and that the damage is irreversible, leaving no capacity for restoration. However, this does not mean that the brain will be as good as a ‘living’ brain; the brain cannot function normally and it may lack awareness or consciousness. Further studies may still have to be conducted, though. In the meantime, this breakthrough opens doors towards research that may help scientists better understand and find probable cure to brain diseases and brain injuries.

Discovery of New Human Species

Scientists have discovered a new human species called Homo luzonensis, recovered from the Callao Cave in Luzon island, northern Philippines. The samples recovered were seven teeth and six bones of at least three members of the said species and were dated from 50,000 to 67,000 years ago. An analysis conducted on the samples concluded that these bones were never seen before and did not match any other species from the Homo family. According to the study, the H.luzonensis might have lived alongside other Homo members such as the Neanderthals, Denisovans from Siberia, and Flores from Indonesia. The discovery tells us how little we still know of our own genus and that there are still a lot to learn about our origins, which in turn will tell us who we are.

Gene Therapy Curing ‘Bubble Boy Disease’

Thanks to an experimental gene therapy, eight infants with ‘bubble boy disease,’ a severe immune disorder, were cured. Those with the said disorder, which is caused by a specific gene mutation, have little to no immune protection, which makes them vulnerable to life-threatening infections. The scientists genetically engineered altered versions of HIV, a virus which typically attacks the immune system but which in this case does the opposite. Sixteen months after the therapy, the infants have yet to experience serious side effects and are actually developing normally. They will still be monitored for a longer period for any long-term side effects. The technique used in this study can be used in other gene therapies for other blood disorders.

3D Printed Tiny Heart from Human Cells

3D printing continues to make its mark in the scientific world. The latest development is 3D printing a tiny heart from human cells done by researchers at Tel Aviv University in Israel. It is much smaller than the normal human heart and more research will be done to improve its functionality and size. But it is a great start in addressing the problem of shortage in transplant organs available to patients. Once it becomes fully-developed and made available to the public, the 3D-printed organs will also be ‘personalized’ or customized to each patient, eliminating the risk of complications with transplanting foreign tissues in the body.

The American Robin – An Amazing Bird You Should Know

If you live in North America, you must have come across the beautiful, mesmerizing American Robin –the long-time icon of North America. This beautiful bird is quite common in sight –especially during the spring season. The North American Robin is known for its characteristic orange belly and its lovely voice.

If you are a nature-lover, then you can know more about this interesting bird. Here are some interesting facts about American Robin that you would love to know:

  • Robins are immensely popular birds –both in North America as well as in Europe. Moreover, it is considered as the National Bird of Great Britain.

 

  • The male American Robin is known for singing marvelously –humming to the most beautiful tones you will ever come across. You would observe the male American Robin singing as the last bird until the sun sets.

 

  • The American Robin is regarded as the state bird for Michigan, Wisconsin, and Connecticut.

 

  • Robins are known to have a sweet tooth as well. Right from sweet berries to cakes, and even pastry dough –these are some of their favorite

 

  • You would be confused by the surprisingly similar appearances of the male & female Robins. By looking closer, you would only observe that the female Robin appears slightly duller in the shade than the male counterpart.

 

  • In the past decades, the Robins were mostly hunted for their meats. However, due to the declining population, the American Robins remain protected under the United States Migratory Birds Act.

 

  • Heard of drunk Robins? Yes, that is true! The American Robins are known to sometimes flock to fermented berries. Once they ingest large quantities of fermented berries, the Robins appear drunk and reflect behaviors like falling or tripping over while walking and others.

 

  • The American Robins are quite famous for their running as well as stopping behaviors. It turns out to be one of the main characteristics that distinguish Robins from the others.

 

  • The American Robin is also famous as a major carrier of the West Nile virus. The Robin is known to hold the virus longer in comparison to other species –therefore, they tend to spread it more than the mosquitoes.

Ancient American Dogs Wiped Out by Expanding European Civilization

The ancient dogs of America that had arrived in the region along with the human beings around 10,000 years ago had been alter on wiped out from the region & existence by the expanding European Civilization. This fact was laid down by an all-new study. In addition to the few genes that are found in the modern-day dogs, the only remaining trace of the original dogs of America back then in the canines of the current era are found through the common form of canine tumor.

The history of the evolution of dogs in the world has always been complicated. This is because the dogs of today are more like a complex mixture of genes belonging from several breeds. A new study had observed over 71 archeological dogs by collecting & studying the respective genes from the remains found in Siberia & North America. These genes have been compared with the dog genes of the modern-day dogs.

A new study has however, tried to dispel the previous results with respect to the origin of dogs in the region of America. This theory posted that the dogs in America evolved from the domesticated wolves. The research & its findings have revealed that there is no particular evidence of this fact. In the given study, the researchers obtained DNA samples from the remains of the dogs that had spanned time (over 1000 years) along with space including Siberia & North America. The research suggested that a particular origin from the Eurasia and more particularly belonging to Siberia were the first dogs to arrive in America more than 10,000 years ago. Later on, the dogs spread across the region wherein they lives & thrived for over 9000 years –remaining isolated from the surrounding world.

However, those dogs were not the ones that you would like to pet today. Instead, the contemporary breeds of dogs have been likely stemmed from the instances of dog species that were brought to the America & its regions more than 1,000 years ago as per a new study. These included the Arctic dogs that were brought in by the Thule people some thousand years ago. These arctic dogs were the ancestors to the modern-day species including Greenland dogs, malamutes, and huskies. These dogs were introduced into the European region somewhere around the 15th century. Similarly, the Siberian Huskies were brought to the American Arctic region somewhere during the Alaskan Gold Rush period.

Devastating Effects of the Colonization Over Dog’s Population

The introduction of the European dogs has been by far considered to have created the biggest impact. There have been suspected several reasons for the wiping out of the ancient American dogs from their existence. The European colonists viewed the native dogs as some kind of pests and thus, freely killed them. At the same time, some of the Spanish explorers would come across lack of food and they would turn to the native dogs as forms of food back then. All of these factors led to the extinction of the ancient native dogs in America.

Tips to Reduce Individual Carbon Footprints

The world we live in today is contributing massively to significant global warming. Owing to the immense adverse effects of global warming to our planet, it is high time that we consider taking effective steps towards reducing our sources of pollution & global warming. Though the government authorities of most of the countries take up preventive measures towards preventing pollution, it is the responsibility of each individual out there to reduce carbon footprints on a personal level.

If you are looking forward to contributing to reducing carbon footprints individually, then here are some steps that you can take up:

  • Consider Alternatives to Driving: Whenever possible, consider walking on your own or taking up some public means of conveyance for avoiding your individual carbon emissions completely. Public transportation and carpooling can drastically help in reducing carbon dioxide emissions by spreading them out across several riders effectively.

 

  • Insulate & Seal Your Home: Try reducing air leaks and drafts with insulation, caulk, and effective weather stripping. There are several countries offering specialized programs as well as incentives towards facilitating this. You can consider taking up professional help from the same.

 

  • Add Solar Panels: Solar panels might appear an expensive affair to many. However, it can turn out to be an effective one-time investment towards reducing your individual carbon footprints to a greater extent. You can try installing solar panels to the roof of your home. This can turn out to be immensely energy-efficient and can save the emission of excess amounts of carbon dioxide through other means of energy production.

 

  • Cut Meat Consumption: For those who might not be aware of the fact that it takes a lot of resources including water and energy in raising a meat industry, it is high time that you consider going vegetarian or vegan. The beef and dairy industry contributes a lot to deforestation and wastage of the earth’s natural resources like forests and water.

 

  • Reuse & Recycle: This turns out to be the golden rule of reducing your carbon footprints on this planet. As per a recent study, it has been revealed that around 20 percent of the overall greenhouse gas emissions come from the provision of goods. This implies the extraction & production of resources, transportation, and the eventual disposal of goods which would also include product packaging, passenger vehicles, and building components. When you buy used products & try recycling or reselling the items that you might no longer use, you are dramatically reducing your overall carbon footprints.

 

  • Support Green & Clean Energy Sources: Whenever it is possible for you, try advocating for cleaner & greener alternatives to fossil fuels. These alternatives could include solar energy, wind energy, hydroelectric energy, geothermal, organic energy, and so more.

 

  • Be Smart Electric-Savvy: If you happen to be an electric appliance-enthusiast, then it is vital that you should act like a smart user. There are several energy efficient options when it comes to buying electrical appliances like refrigerators, air conditioners, and so more

 

Be a responsible human being!
