SpaceX launches first direct-to-cell satellites – RCR Wireless News

Posted: January 7, 2024 at 7:37 pm

On Tuesday evening, SpaceXs Falcon 9 rocket launched from Vandenberg Space Force Base in California with 21 Starlink satellites in tow.

Those satellites included the first six Starlink satellites with direct-to-cellular capabilities, essentially acting as cell towers in space and enhancing terrestrial cellular networks with the ability for regular cellular devices to access satellite-based texting, calling and mobile data, according to SpaceX.

Starlink has been lining up mobile network operator partners for reciprocal access that include T-Mobile US, Rogers in Canada, Japans KDDI, Optus in Australia and One NZ in New Zealand, as well as Salt in Switzerland and Entel in Chile and Peru.

T-Mobile US and Starlink announced their partnership in 2022, aimed at providing ubiquitous texting capabilities in the U.S. and allowing Starlink to gain access to some of T-Mobiles midband spectrum. The carrier said at the time that the direct-to-cell capabilities would be able to connect the vast majority of smartphones already on its network.

SpaceXs founder, CEO and CTO Elon Musk said at the time that he anticipated that the Starlinks new satellites would be able to deliver two to four megabits per cell zoneenough for thousands of voice calls, and millions of text messages.

An African psychedelic plant significantly alleviated the symptoms of war veterans suffering from traumatic brain injuries (TBIs), according to another new study.

Ibogaine, a naturally occurring compound found in the roots of the African shrub iboga, was found to successfully improve functioning, PTSD, depression and anxiety in military veterans.

The plant-based psychoactive drug, which has been used in Africa for a thousand years during spiritual and healing rituals, was also found to contain no adverse side effectswith some veterans saying the experimental treatment saved their lives.

Hundreds of thousands of troops serving in Afghanistan and Iraq have sustained TBIs in recent decades, and these injuries are suspected of playing a role in the high rates of depression and suicide seen among military veterans. With mainstream treatment options not fully effective for all veterans, researchers have sought therapeutic alternatives.

Ibogaine has gained notoriety in scientific communities for its potential to treat opioid and cocaine addiction, because it increases signaling of several important molecules within the brain, some of which have been linked to drug addiction and depression.

Traumatic brain injury is defined as a disruption in the normal functioning of the brain resulting from external forcessuch as explosions, vehicle collisions or other bodily impacts. Such trauma can lead to changes in the structure of the brain, which, in turn, contributes to neuro-psychiatric symptoms.

Stanford Medicine researchers discovered that ibogaine, when combined with magnesium to protect the heart, safely and effectively reduces symptoms like PTSD, anxiety, and depressionand improves functioningin veterans with TBI.

Their new study, published on Jan. 5 in Nature Medicine, includes detailed data on 30 veterans of U.S. special forces.

No other drug has ever been able to alleviate the functional and neuropsychiatric symptoms of traumatic brain injury, said Nolan Williams, MD, an associate professor of psychiatry and behavioral sciences. The results are dramatic, and we intend to study this compound further.

Since 1970 ibogaine has been designated as a Schedule I drug, preventing its use within the U.S., but clinics in both Canada and Mexico offer legal ibogaine treatments.

There were a handful of veterans who had gone to this clinic in Mexico and were reporting anecdotally that they had great improvements in all kinds of areas of their lives after taking ibogaine, Williams told Stanford Medicine News. Our goal was to characterize those improvements with structured clinical and neurobiological assessments.

Dr. Williams and his Stanford team partnered with VETS, Inc., a foundation that has facilitated psychedelic-assisted therapies for hundreds of veterans. 30 special operations veterans with a history of TBI and repeated blast exposuresalmost all of whom were experiencing clinically severe psychiatric symptoms and functional disabilitieswere recruited after theyd independently scheduled themselves for an ibogaine treatment at a Mexico clinic.

Before the treatment, the researchers gauged the participants levels of PTSD, anxiety, depression and functioning based on a combination of self-reported questionnaires and clinician-administered assessments. Participants then traveled to a clinic in Mexico run by Ambio Life Sciences, where under medical monitoring they received oral ibogaine along with magnesium to help prevent heart complications that have been associated with ibogaine. The veterans then returned to Stanford Medicine for post-treatment assessments.

19 of the participants had been suicidal, and seven had attempted suicide.

These men were incredibly intelligent, high-performing individuals who experienced life-altering functional disability from TBI during their time in combat, Williams said. They were all willing to try most anything that they thought might help them get their lives back.

On average, treatment with ibogaine immediately led to significant improvements in functioning, PTSD, depression, and anxiety. Moreover, those effects were still lasting one month after treatment, when the study ended.

Before treatment, the veterans had an average disability rating of 30.2 on the disability assessment scale, equivalent to mild to moderate disability. One month after treatment, that rating improved to 5.1, indicating no disability.

Similarly, one month later, they experienced average reductions of 88% in PTSD symptoms, 87% in depression symptoms and 81% in anxiety symptoms. Formal cognitive testing also revealed improvements in participants concentration, information processing, memory and impulsivity.

I wasnt willing to admit I was dealing with any TBI challenges. I just thought Id had my bell rung a few timesuntil the day I forgot my wifes name, said Craig, a 52-year-old study participant from Colorado who served 27 years in the U.S. Navy.

Since [ibogaine treatment], my cognitive function has been fully restored. This has resulted in advancement at work and vastly improved my ability to talk to my children and wife.

Before the treatment, I was living life in a blizzard with zero visibility and a cold, hopeless, listless feeling, said Sean, a 51-year-old veteran from Arizona with six combat deployments who participated in the study and says ibogaine saved his life. After ibogaine, the storm lifted.

Importantly, there were no serious side effects of ibogaine and no instances of the heart problems that have occasionally been linked to ibogaine. During treatment, veterans reported only typical symptoms such as headaches and nausea.

The team is planning further studies, along with analysis of brain scans that could help reveal how ibogaine led to improvements in cognition. They also think ibogaines drastic effects on TBI suggest that it holds broader therapeutic potential for other neuro-psychiatric conditions.

I think this may emerge as a broader neuro-rehab drug, said Williams. I think it targets a whole host of different brain areas and can help us better understand how to treat other forms of PTSD, anxiety and depression that arent necessarily linked to TBI.

"I think, Therefore I Am", What Does This Descartes Quote Mean? – Exploring your Mind

Posted: at 7:34 pm

"I think, therefore I am" or "cogito ergo sum" is related to conceiving one's own existence. Let's delve into this quote by Ren Descartes.

Last update: 04 January, 2024

The meaning of this famous Descartes quote may seem obvious, along with the fact that we are rational beings with the ability to think about the world around us. However, we say it with all the cultural baggage that precedes us. There was a time when this wasnt the case, until Descartes arrived on the scene. Hes credited with a remarkable discovery summarized in the phrase: I think, therefore I am.

In this article, well explore the meaning of this discovery and the doctrine behind this intellectual, whos considered one of the most important philosophers of the 17th century. Lets get started!

Ren Descartes was a renowned philosopher and physicist of great importance for the development of rationalism. This current assumes that human beings have the capacity to know through our reason. The relevance of his work lies in the fact that he was one of the first to build the bases and rules to achieve sure and true knowledge.

Firstly, Descartes sought to emancipate the subject from the bonds of dogmatic knowledge. This means that the sources of knowledge must come from ourselves and not from religion or a philosophy built on flimsy foundations.

At the same time, he looked to find that sure path for the development of philosophy in particular and science in general. Therefore, in his various books, he proposed to build the foundations of a new rationalist philosophy. We can name the following most notable works by this philosopher:

In this article, well focus on the Discourse on the Method and Metaphysical Meditations. This is because the famous Descartes quote, I think, therefore I am, appears in both of them.

The original formulation of the Descartes quote, I think, therefore I am, is written in Latin as cogito ergo sum. It means that in the act of thinking, a person can conceive their own existence. That is, this reflection considers that being and existing are mutually identified, and one cant be without the other.

To interpret the phrase as a whole, its a good idea to disassemble it into parts. In this way, the word cogito is the act of thinking. For its part, ergo means later, although its not interpreted with an adverb of time, rather, its a simultaneous experience. Finally, sum means to be.

And having noticed that there is nothing at all in this,I think, therefore I am, which assures me that I am speaking the truth except that Isee very clearly that in order to think one must exist.[/atomik -quote]

As an article in the journal Studium maintains, Descartes intuits a concrete existence linked to the act of thinking. In other words, its an internal experience thats the product of a rigorous philosophical method known as methodical doubt.

Its worth mentioning that the phrase appears for the first time in Descartes work Discourse on the Method, specifically, in the fourth part. In it, the philosopher proceeds to make a summary of what will later be explained with greater precision in the Metaphysical Meditations.

Descartes arrives at cogito ergo sum through methodical doubt. But what does this consist of? This is a provisional and necessary doubt to carry out the philosophical objective that he set for himself. It consists of discovering the sure path for the development of philosophy and science.

This doubt is characterized by considering all our past opinions as false, especially those that come from our senses. Furthermore, the act of doubting represents freedom from the ties of the past that constricted our consciousness.

Its important to highlight that Descartes considers doubt as an act of thought. In this regard, doubt is a source to discover cogito ergo sum, as by doubting, we make use of our thinking, reaffirming not only our thinking but also our own existence. Lets remember at this point that thinking and existing are connected.

In this way, cogito ergo sumassures a doubting self. It arises from the very act of doubting.

One of the most important rules of thought for Descartes is clarity and distinction. Furthermore, its the first that the philosopher exposes in Discourse on the Method. The fundamental thing about it is that it represents a criterion of truth. This means that everything that I conceive as clear and distinct is, necessarily, true.

In this way, said clarity and distinction are an immediate intuition that our reason captures spontaneously. In this aspect, Descartes considers intuition to be an absolute truth.

The first intuition he discovers is I think, therefore I am. Therefore, he represents the first absolute truth that serves as a model to find the others.

Already, at this point, we can say that Descartes defines the human being as a thinking reality. In Latin, this is known as res cogitans. Therefore, the Descartes quote, I think, therefore I am, is an immediate intuition that clearly sees that in order to think, one must exist. In this way, we apprehend our existence in the very act of thought.

So, according to this philosopher, thought is not only an essential attribute of the human being, its the most important. The most notable thing about this is that it not only defines the human being but, furthermore, the evidence is such that it cant be doubted.

Ren Descartes is considered the father of modernity, but the influence of his thought isnt limited to this. In this regard, an article published by the journal CIENCIA ergo-sum reviews some relevant issues to consider in Cartesian philosophy.

Firstly, theres no doubt about the revolution of the Cartesian theory of autonomous reason. Its represented through the phrase cogito ergo sum. In this way, Descartes is considered to have given rise to the notion of I, that is, a subjectivity thrown into the world.

Furthermore, he introduces a new conception of the human being, defined through his thinking activity. This idea will endure not only in the development of later philosophy, but also in science itself. This is because scientists began to address the world with as pure a view as possible.

The philosophy of Ren Descartes represented a radical change in the way of thinking about human beings and science in general. Born on March 31, 1596 at La Haye in Touraine, France, his philosophical goal was to lay the foundations for science in general and philosophy in particular. This earned him the fame of being one of the most important thinkers of the 17th century.

With the formulation of cogito ergo sum, he opened a new horizon of thought that put human reason at its center. Not only that, Descartes also systematically developed a method with which one could hope to find the truth without any error.
