The Pentagon has set out to conquer the “underground world”

Mankind has conquered nearly all places on the surface of the planet throughout the ages. From dangerous seas to the highest mountains, our civilization has seized control of almost every corner of Earth’s surface. Now, we may soon start doing the same thing to the underworld according to a new military project by DARPA, the Defense Advanced Research Projects Agency of the United States. The new initiative challenges participants from all over the world to propose pioneering methods to develop systems that can help in the investigation of habitable underground networks

“One of the consequences of the increase in world population and urbanization is the need for more living spaces, which makes the search and development of underground infrastructure increasingly interesting,” says Timothy Chung, program director of the DARPA Tactical Technology Office (TTO) in a recently published video (see below).

According to Timothy Chung, program director of the DARPA Tactical Technology Office (TTO), “One of the consequences of the increase in world population and urbanization is the need for more living spaces, which makes the search and development of underground infrastructure increasingly interesting.”

In that line of thinking, the Pentagon has just launched a totally unexpected challenge to researchers.

Titled “Underground Challenge of the Advanced Defense Research Projects Agency of the USA” (DARPA Subterranean or “SubT” Challenge), it’s a call to explore new possibilities in tracking, navigation, and exploration of underground environments, as noted by Space.com.

This initiative invites participants from all over the world to propose pioneering methods to develop systems that can help in the investigation of habitable underground networks, even with unpredictable conditions that are dangerous for humans.

“One of the main limitations facing warfighters and emergency responders in subterranean environments is a lack of situational awareness; we often don’t know what lies beneath us,” Chung, said in a statement.

“The DARPA Subterranean Challenge aims to provide previously unimaginable situational awareness capabilities for operations underground.”

Through the “SubT” Challenge, the Pentagon invites the scientific and engineering community, as well as the general public, to use their creativity in order to provide new technologies and ideas to make access the inaccessible, considering time as something essential.

According to the director of the TTO, Fred Kennedy, “we are now at a point where developments in robotics, autonomy and even biological systems will allow us to explore underground areas that are very dangerous for humans.”

Those who are interested in this challenge will compete in solving extreme problems as helping people navigate in the unknown, through unprecedented treacherous subterranean conditions where time is of the essence, according to the statement.

As noted by Space.com, The final competition, which will take place in 2021, will include three challenges that include operating in one of three environments: a network of man-made human-made tunnels, a subterranean municipal-transit system and a network of underground natural caves.

The final event will challenge teams to navigate through networks that include parts of all three environments. The grand-prize winners will take home $2 million. The deadline to apply is Jan. 18, 2018.

Through the DARPA Subterranean Challenge, we are inviting the scientific and engineering communities — as well as the public — to use their creativity and resourcefulness to come up with new technologies and concepts to make the inaccessible accessible,” Kennedy said in the statement.

Eight black rhinos die after move to new park

There are only around 5,500 black rhinos left on Earth.

The critically endangered rhinos had been living in a new sanctuary in southern Kenya when the disaster occurred.

A total of fourteen black rhinos had been moved from the Nairobi and Lake Nakuru national parks to Tsavo East national park as part of an operation carried out in collaboration with WWF Kenya.

The goal was to increase the country’s overall number of black rhinos by creating new populations in suitable areas, however disaster struck when eight of the new arrivals unexpectedly wound up dead.

It is believed that the rhinos had succumbed to poisoning due to the higher salt content in the water.

Kenyan conservationist Paula Kahumbu described the incident as “a complete disaster”.

An investigation has since been launched in an effort to find out how this could have happened.

“The eight dead rhinos were among those that had been moved to the sanctuary in an initiative to start a new population in line with the National Rhino Conservation and Management Strategy,” the Kenyan Ministry of Tourism and Wildlife said in a statement.

“This kind of mortality rate is unprecedented in Kenya Wildlife Service operations.”

Cannabis: A Lost History

Dr. Mercola, Guest
Waking Times

Cannabis, better known as marijuana, has been used for its medicinal properties for thousands of years. It’s been heralded as a “cure-all,” revered for its healing properties, particularly for pain but also as a potential anticancer treatment. Marijuana was a popular botanical medicine in the 19th and 20th centuries, common in U.S. pharmacies of the time.

It wasn’t until 1970 that the herb was declared a Schedule 1 controlled substance in the U.S., a classification reserved for drugs with “high potential for abuse” and “no accepted medical use.” Three years later the Drug Enforcement Agency was formed to enforce the newly created drug schedules, and the fight against marijuana use began. In light of its history as a global panacea for all sorts of ills, it’s classification as a controlled substance is particularly unjustified.

As noted in the documentary “Cannabis: A Lost History,” written, directed and narrated by Chris Rice, marijuana has been “an integral part of human civilization,” featuring in ancient Japanese cave paintings, as well as Chinese and Siberian burial rites dating back to 3000 B.C. Based on the evidence — especially the discovery that the human body is equipped with a cannabinoid system — it appears our relationship with cannabis goes back to the very dawn of the human species.

Historical remnants from all around the world also reveal the importance of cannabis in medicine and spirituality. For example, Taoist monks in ancient China burned cannabis as incense, and consumed it with ginseng — a combination thought to open your psychic centers, allowing you to see the future. Cannabis was also revered as sacred in Hinduism, Zoroastrianism and Buddhism.

Cannabinoids and the Cannabinoid Receptor System

The marijuana plant contains more than 60 different cannabinoids; chemical compounds the human body is uniquely equipped to respond to. The two primary ones are cannabidiol (CBD) and tetrahydrocannabinol (THC), the latter of which is the psychoactive component. Cannabinoids interact with your body by way of naturally occurring cannabinoid receptors embedded in cell membranes throughout your body.

There are cannabinoid receptors in your brain, lungs, liver, kidneys, immune system and more; the therapeutic (and psychoactive) properties of marijuana occur when a cannabinoid activates a cannabinoid receptor. Your body also has naturally occurring endocannabinoids similar to THC that stimulate your cannabinoid receptors and produce a variety of important physiologic processes.

So, your body is actually hard-wired to respond to cannabinoids through this unique cannabinoid receptor system. We still don’t know exactly how far its impact on your health reaches, but to date it’s known that cannabinoid receptors play an important role in many body processes, including metabolic regulation, pain, anxiety, bone growth and immune function.1

The Earliest History of Cannabis

According to the featured video, the earliest written references to cannabis are found in the Chinese Materia Medica, said to be written by Shen Nung around 2800 B.C. The oldest known copy of this book dates back to 50 B.C. Nung is one of three “celestial emperors” revered in the Chinese culture. “Half emperor, half deity, he is said to have ruled over China long before written history,” Rice says.

Nung is credited with inventing agriculture — including the hoe, plow and irrigation — as well as acupuncture and Traditional Chinese Medicine (TCM). Often depicted draped in leaves and chewing on various plants, Nung was the first pharmacologist, experimenting with and recording the health effects of plants. Nung documented around 100 different conditions that responded well to cannabis, including goutrheumatism, malaria and absentmindedness.

Before Nung declared its medicinal attributes, the cannabis plant, called “ma” in Chinese, had been used for centuries in the production of textiles, paper, rope and pottery. Around 200 A.D., a Chinese physician named Hua Tuo performed the first surgery using an anesthetic — a formula called Ma Fei San, which translates to “cannabis boiling powder.”

For thousands of years, cannabis remained one of the 50 essential plants used in TCM. It was only removed from widespread use in recent times due to its controversial legal status. The film also reviews the history of cannabis in Indian culture. In the Vedas, the sacred text of India, cannabis (bhang) is listed as one of five sacred plants, and the Hindu god Shiva is referred to as “Lord of the bhang,” meaning the Lord of cannabis.

According to the Mahanirvana, “bhang is consumed in order to liberate oneself,” and liberation is the path to immortality. The ancient Egyptians, Persians and Greeks also used cannabis in a variety of ways, including medicinally and for spiritual upliftment. References to cannabis are even found in Islamic, Judaic and Christian texts, although an error in translation appears to have crept into the Bible along the way. The original Hebrew term “kaneh bosm,” or cannabis, is found several times in the Old Testament.

In Exodus, chapter 30, God instructs Moses on how to make a holy anointing oil: “Take for yourself choice spices: 500 shekels of pure myrrh, half as much fragrant cinnamon, 250 shekels of kaneh bosm and 500 shekels of cassia and mix these with olive oil.” In more modern Bibles, kaneh bosm has been translated as sweet calamus. The problem is this plant does not have the properties that the Bible ascribes to kaneh bosm.

According to the film, a 12th century painting found in a Sicilian basilica also “appears to show Jesus near a pot leaf.” The painting is titled “Jesus healing the blind.” Interestingly enough, “modern scientific studies have since proven that cannabis delays retinal degeneration,” Rice says.

The American History of Cannabis

In the U.S., the prohibition of marijuana began to turn in 1996 when California became the first state to legalize medical cannabis. Since then, many others have followed. In 2012, Colorado and Washington state became the first states to legalize its recreational use. Today, the majority of Americans support cannabis either as a medicine, for recreational use, or both. Surveys show at least 4 in 10 Americans have tried marijuana, while nearly 60 percent support full legalization.

A 2013 survey found a majority of physicians — 76 percent — also approve of the use of medical marijuana.2 CNN’s chief medical correspondent and neurosurgeon Sanjay Gupta also made a highly publicized reversal on his marijuana stance after the production of his two-part series “Weed,” which aired in 2014.3

The American history of cannabis goes back to our Founding Fathers, who cultivated the plant for industrial purposes. George Washington, for example, is said to have grown more than 100 hemp plants at his home in Mount Vernon, Virginia.4 Cannabis is called hemp when being used for its fibers, which are extracted from the stem and constructed into rope, clothing and paper.

Hemp plants are low in tetrahydrocannabinols (THC) levels and therefore do not get you high. During the 17th century, hemp was viewed as an important cash crop. It was used for rope by navies around the world, and as a thick durable linen ideal for clothing and packaging heavy materials. Hemp seed oil was used in soaps, paints and varnishes.

The battle that has raged over marijuana is a long and arduous one. You can read a brief history of marijuana prohibition in the Huffington Post.5 Still, movements to legalize marijuana have persisted throughout, starting as early as 1973, when Oregon became the first state to decriminalize cannabis. The most successful movement to date, and the one that produced the first legal marijuana market in decades, is the medical marijuana movement.

Medical cannabis is now legal in 30 U.S. states,6,7 the majority of which allow limited use of medical marijuana under certain medical circumstances, although some limit medical cannabis to oils or pills only. Eight states have legalized it for recreational use.

A number of municipalities have also created their own marijuana rules, either decriminalizing it, legalizing it, enacting rules that direct city law enforcement to cease arresting individuals for marijuana possession, or making cannabis offenses the lowest priority for law enforcement.

What Can Cannabis Treat?

As mentioned, your body makes its own cannabinoids, similar to those found in marijuana, but in much smaller amounts. These endocannabinoids appear to perform signaling operations similar to your body’s neurotransmitters, such as dopamine and serotonin. Cannabinoid receptors can be found on cell membranes throughout your body. In fact, scientists now believe they may represent the most widespread receptor system.8

The fact that your body is replete with cannabinoid receptors, key to so many biological functions, is why there’s such enormous medical potential for cannabis. Even though research has been limited by its classification as a Schedule 1 controlled substance, its list of medicinal benefits is still quite long. For example, cannabis has been found useful in the treatment of:9,10,11,12,13

Mental disorders, including post-traumatic stress disorder, mood disorders and Tourette’s syndromeSeizure disorders such as epilepsy
Pain (in one study,14 three puffs of marijuana a day for five days decreased chronic nerve pain)Rheumatoid arthritis
Spasticity, dystonia and tremorsHeart disease
Multiple sclerosis and other autoimmune issuesAutism
Parkinson’s diseaseChronic fatigue syndrome
Cancer, including melanoma, leukemia and cancers of the brain, breast, prostate, lung, head and neck,15thyroid, colon and pituitaryNausea, vomiting and lack of appetite16
InsomniaGlaucoma
HIV/AIDSAmyotrophic lateral sclerosis
Crohn’s diseaseAnorexia
Alzheimer’s disease (the U.S. government, through the Department of Health and Human Services, holds a patent on CBD as a neuroprotectant)Hepatitis-C
Cachexia (wasting syndrome)Asthma
Drug dependency and withdrawalHigh blood pressure

Among the most exciting research is that on cancer. Not only does cannabis help with the unpleasant side effects of traditional chemotherapy (including pain, nausea and insomnia), but the cannabis itself appears to be a natural chemotherapy agent.17

Researchers have found cannabis is pro-apoptotic, meaning it triggers cellular suicide of cancer cells while leaving healthy cells untouched, and anti-angiogenic, meaning it cuts off a tumor’s blood supply. Dozens of studies point to marijuana’s effectiveness against many different types of cancer. For example, Harvard researchers found THC cuts tumor growth in lung cancer while significantly reducing its ability to spread.18

Medicinal Marijuana Can Help Stem Death Toll From Narcotic Pain Killers

Another area where cannabis offers great hope is in the treatment of pain. Overdoses from narcotic pain killers are now the leading cause of death among Americans under the age of 50, and pharmaceuticals in general have for decades been among the leading causes of death in the U.S. According to Dr. Margaret Gedde, owner and founder of Gedde Whole Health and the Clinicians’ Institute of Cannabis Medicine, research clearly confirms that cannabis is safer and less toxic than many prescription drugs.

This includes liver and kidney toxicity, gastrointestinal damage, nerve damage and death. Moreover, cannabinoids often work when pharmaceutical drugs fail, so not only is cannabis safer but it’s typically more effective. Besides treating intractable seizures, one of the strongest areas of research regarding marijuana’s health benefits is pain control.

In 2010, the Center for Medical Cannabis Research released a report19 on 14 clinical studies about the use of marijuana for pain, most of which were FDA-approved, double-blind and placebo-controlled. The report revealed that marijuana not only controls pain but in many cases, it does so better than pharmaceutical alternatives.

If you compare opioids to marijuana, marijuana is unquestionably safer. Contrary to opioids, a cannabis overdose cannot kill you because there are no cannabinoid receptors in your brain stem, the region of your brain that controls your heartbeat and respiration.

What’s more, marijuana has been shown to ease withdrawal symptoms in those trying to wean off opioids, which are extremely addictive. In states where medical marijuana is legal, overdose deaths from opioids decreased by an average of 20 percent after one year, 25 percent after two years and up to 33 percent by years five and six.

Big Pharma Takes Aim at CBD

Unfortunately, but not surprisingly, the drug industry is now trying to turn CBD oil into a drug, and hence illegal for sale as a supplement.20 Showing promise for a wide range of ailments, the drug industry sees cannabis as major competition, and rightfully so. June 25, 2018, GW Pharmaceuticals became the first company to gain FDA approval for a CBD-based drug.21,22

The drug in question, Epidiolex, was approved for the treatment of intractable childhood epilepsy in children aged 2 and older. Another product called Sativex is also awaiting FDA approval. Sativex has already been approved in a number of other countries for the treatment of spasticity in multiple sclerosis patients. In a June 25 statement,23 FDA Commissioner Dr. Scott Gottlieb stated:

“This product approval demonstrates that advancing sound scientific research to investigate ingredients derived from marijuana can lead to important therapies … This is an important medical advance. But it’s also important to note that this is not an approval of marijuana or all of its components. This is the approval of one specific CBD medication for a specific use. And it was based on well-controlled clinical trials evaluating the use of this compound in the treatment of a specific condition.

Moreover, this is a purified form of CBD. It’s being delivered to patients in a reliable dosage form and through a reproducible route of delivery to ensure that patients derive the anticipated benefits. This is how sound medical science is advanced. So today, in addition to celebrating this scientific achievement and the medical advance that it represents … we should also reflect on the path that made this possible.

It’s a path that’s available to other product developers who want to bring forth marijuana-derived products through appropriate drug development programs. That pathway includes a robust clinical development program, along with careful review through the FDA’s drug approval process. This is the most appropriate way to bring these treatments to patients. This process also includes a review of the purity of a new drug and manufacturing controls.”

FDA Cracks Down on CBD Supplements

As expected, with its approval of the first CBD drug, the FDA has increased its scrutiny of companies making CBD extracts. In November 2017, four Colorado businesses received FDA warning letters for making “illegally unsubstantiated health claims” on their CBD products.24 In a November 1 press release, the FDA said:25

“[T]he agency today issued warning letters to four companies illegally selling products online that claim to prevent, diagnose, treat or cure cancer without evidence to support these outcomes … The deceptive marketing of unproven treatments may keep some patients from accessing appropriate, recognized therapies to treat serious and even fatal diseases.

The FDA has grown increasingly concerned at the proliferation of products claiming to treat or cure serious diseases like cancer. In this case, the illegally sold products allegedly contain cannabidiol (CBD), a component of the marijuana plant that is not FDA approved in any drug product for any indication.”

The warning letters26 also rejected claims that CBD oil can be classified as dietary supplements since Investigational New Drug (IND) applications have been submitted for the CBD-containing drugs Sativex and Epidiolex. This suggests the agency is not just aiming to clean up the cannabis industry’s propensity to make illegal claims; it also raises concerns that the legality of all CBD products is in question now that at least one CBD-containing drug has been approved.

Many CBD Products Are Mislabeled

The FDA scrutiny is not entirely unwarranted, however. A November 2017 study27 in JAMA found only 30 percent of CBD extracts sold online accurately list the amounts of cannabinoids on the label. And, while CBD is very safe, accuracy is still of utmost importance.

The FDA and DEA will also use information like this to push CBD into pharma-only territory. The JAMA study used triplicate tests to analyze the cannabinoid content of 84 CBD products purchased online, along with a 10-point method validation procedure. A 10 percent plus or minus allowable variance was used, which is consistent with herbal product labeling in general in the U.S. According to the authors:

“Observed CBD concentration ranged between 0.10 mg/mL and 655.27 mg/mL (median, 9.45 mg/mL). Median labeled concentration was 15.00 mg/mL … With respect to CBD, 42.85 percent of products were underlabeled, 26.19 percent were overlabeled, and 30.95 percent were accurately labeled.

Accuracy of labeling depended on product type, with vaporization liquid most frequently mislabeled … and oil most frequently labeled accurately … Concentration of unlabeled cannabinoids was generally low; however, THC was detected (up to 6.43 mg/mL) in 18 of the 84 samples tested … Of tested products, 26 percent contained less CBD than labeled, which could negate any potential clinical response.

The overlabeling of CBD products in this study is similar in magnitude to levels that triggered warning letters to 14 businesses in 2015-2016 from the U.S. Food and Drug Administration (e.g., actual CBD content was negligible or less than 1 percent of the labeled content), suggesting that there is a continued need for federal and state regulatory agencies to take steps to ensure label accuracy of these consumer products.”

Educate Yourself on the Scientific Evidence Supporting Medical Marijuana

If you’re still on the fence when it comes to giving people the right to use medical marijuana, one of the best ways to still your fears is to look at the research, and look at what doctors are doing in clinical practice. To start, I recommend listening to my interviews with Geddeand Dr. Allan Frankel, in which they discuss many of the medical benefits of cannabis. Other helpful resources include:

The International Association for Cannabis website, which maintains a Clinical Studies and Case Report page.28
Cancer.gov,29 the U.S. government’s cancer website, contains research relating to the use of cannabis
PubMed30 is a searchable public resource containing a vast amount of medical literature, including studies involving cannabis
The Journal of Pain31 is a publication by the American Pain Society with a long list of studies on the pain-relieving effects of cannabis
National Institute on Drug Abuse32 provides information about preclinical and clinical trials underway to test marijuana and various extracts for the treatment of a number of diseases, including autoimmune diseases such as multiple sclerosis and Alzheimer’s disease, inflammation, pain and mental disorders
ProCon.org lists 60 peer-reviewed studies on medical marijuana and cannabis extracts published between 1990 and 2014, listed by the condition treated33

Photos of an Incredible Secret Rainforest Hidden in The Heart of Africa –

Atop Mount Lico in northern Mozambique is a site that few have had the pleasure of seeing – a hidden rainforest, protected by a steep circle of rock.

Though the mountain was known to locals, the forest itself remained a secret until six years ago, when Professor Julian Bayliss spotted it on satellite imagery. It wasn’t until last year, however, that he revealed his discovery, at the Oxford Nature Festival.

We recently visited the 700 metre-high mountaintop rainforest in an expedition organised by Bayliss, in collaboration with Mozambique’s Natural History Museum and National Herbarium. As far as anyone knew (including the locals), we would be the first people to set foot there (spoiler: we weren’t).

Lico Mountain of Mystery watermark(© Jeffrey Barbee/Allianceearth.org)

Since the rainforest’s discovery, Lico has received worldwide attention. That it captured the public’s imagination speaks volumes about how rare such places are. Humans are nothing if not adventurous, pushing our range boundaries like no other species can.

But when almost every corner of the planet now shows signs of human activity, how do conservation scientists justify visiting and publicising these last bastions of untrodden nature?

From our perspective, the answer depends on what expeditions like this can teach us about the natural world, our place in it, and how to shepherd the wildest of places through the Anthropocene. Standing back and crossing our collective fingers is not always a winning strategy.

This expedition formed part of a long-standing research programme into these mountains, that aims to provide evidence to legally protect Mozambique’s mountain forests.

Lico mountain of mystery header(© Jeffrey Barbee/Allianceearth.org)

Currently none of northern Mozambique’s mountains are formally protected, either nationally or internationally. Finding new species is one way to highlight the importance of such sites and justify their protection.

As well as exploring Mount Lico, the expedition was the first to undertake a biological survey of nearby Mount Socone. Every bit as majestic and species rich as the iconic Lico, Socone highlights the threat faced by many forests in Mozambique, Africa and elsewhere.

Globally, one football pitch worth of forest is lost every second, driving countless species to extinction. The removal of trees from mountain slopes also leads to soil erosion, flooding in the wet season and water shortages in the dry season.

Map(AllianceEarth.org)

On our first day on Socone, we set out to locate the middle of the forest using a satellite image and GPS. However, the difference between what this image was telling us and what we could see was vast. As we walked towards what the image showed as the heart of lush rainforest, we could see the warm glow of the African sun.

Soon enough, we emerged from beneath the canopy and into newly established farmland. Without the protective cover of the forest, heavy rains will pound these exposed mountain soils, fresh cuts will need to be made, and so the cycle repeats. Media attention on neighbouring Lico, and the new species descriptions coming out of both sites, help to bring these conservation and livelihood issues to the world’s attention.

Time capsules

Our brief footsteps on Lico will soon be overgrown, and the plants and animals that live there will continue to be protected by the same towering cliffs (more than 125 metres high) that have saved them up to now (without the help of world-class climbers, our expedition would not have been possible).

But the impact of people goes far beyond where we have actually managed to set foot. Since the industrial revolution, humans have increased the amount of carbon dioxide in the atmosphere to levels higher than at any time in the past 400,000 years, increasing temperatures and changing weather patterns.

Despite being situated on a fortress of rock, Lico’s forest is vulnerable to climate change, like every other ecosystem on the planet.

alliance earth blog african volcano 4(© Jeffrey Barbee/Allianceearth.org)

The contrast between protection from direct human activities but exposure to climate change means that Lico has a lot to teach us. Most forests experience both of these processes simultaneously, and so it is difficult to unravel their relative and interacting impacts.

Through the data collected on Lico, Socone and other forests worldwide, we gain a greater understanding of how human disturbance affects the ability of forests to respond to environmental change.

Lico is a rare data point on this map: millennia of climate change and ecological response, played out in the absence of direct human disturbance.

Lico Mountain of Mystery 5(© Jeffrey Barbee/Allianceearth.org)

Reconstructing this history meant digging a two metre-deep pit in the forest, so that we could sample the layers of soil in the order that they accumulated.

We tried to minimise any lasting effects on the forest (the hole was filled and topsoil replaced) but nonetheless, reasonable objections can be made against our disturbing this previously pristine site.

What we gained were a series of time capsules: each little tin of soil contains information on the plants that grew, the fires that burned and the water that flowed, data that will be shared in open-access repositories, allowing people worldwide to investigate this unique site without the need for further disturbance.

What we learn from Lico will help the world understand how forests might be affected by future changes in climate.

So were we really the first humans on Lico? Well, not quite.

alliance earth blog african volcano 1(© Jeffrey Barbee/Allianceearth.org)

To everyone’s surprise, we found ancient pots, ceremonially placed near the source of a stream that flows to a waterfall down the side of the cliff. Were these placed there during a time of drought, as the waterfall ran dry and the crops failed?

The ConversationArchaeologists and climate scientists are investigating. Given the pots pre-date local knowledge, the incredible inaccessibility and lack of any other signs of human activity, Lico’s forest remains one of the least disturbed on the planet.

One thing’s for sure though – humans really do get everywhere.
