Healthcare Among Archaic Humans

 


The skull of a child of around 12 years of age at time of death found among other human remains at Qafzeh in Israel. This individual - Qafzeh 11 - suffered a compound cranial trauma, indicated with arrows, with signs of healing. This individual was buried after people cared for him, possibly for an extended period of time.

Dr. Johnn Hawks, a world renown paleoanthropologist, has written:

There is growing evidence of healthcare in the archaeological and skeletal record of hominins. In our article we point to some of the famous cases, like the KNM-ER 1808 individual, who lived around 1.6 million years ago and survived for some time with debilitating and painful periosteal reaction and cortical bone thickening. In the Middle Pleistocene, the case of craniosynostosis of the Cranium 14 individual from Sima de los Huesos is notable; in the Late Pleistocene record, Neanderthals with evidence of extensive osteoarthritis, losses of limbs, and near-complete loss of teeth are also very well known.



Some of the humans buried at Qafzeh Cave were covered with red ocher, a symbolic blood covering, suggesting the hope for life after death.

The Glow of Life

 



Biophotons (from the Greek βίος meaning "life" and φῶς meaning "light") are photons of light in the ultraviolet and visible light range that are produced by a biological system.

Catalina Curceanu is a nuclear and quantum physicist at Italy’s National Institute of Nuclear Physics–National Laboratories of Frascati. She has been studying biophotons, a by-product of normal cellular processes, though it’s unclear how they form. 

Normal cellular processes create biophotons, though the light is not visible to the naked eye. These spontaneous emissions are thought to be associated with generation of free radicals due to energy metabolic processes.

Quantum physicist Christoph Simon, of the University of Calgary in Canada, believes that when these reactive molecules attack lipids — long links of fatty acids — they produce “a kind of a chain reaction” and energy is released. Some biophotons escape, “about 1,000 photons per square centimeter per second” from our skin, Simon says. It’s about a millionth the intensity of a firefly and can’t be seen with the naked eye.

As early as in 1923, Gurwitsch, a Russian scientist, observed optical radiation during mitosis in onion roots and called it "mitogenetic radiation". Modern biofield theory has extended this hypothesis to postulate electromagnetic interactions between cells for control and for information transfer.

2025 Nobel Prize Winners in Medicine

 



The 2025 Nobel Prize in Physiology or Medicine has been awarded to Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi for their work on how our immune system is prevented from attacking our organs.

The three scientists' research provides insights into keeping the immune system under control to fight microbes and avoid autoimmune diseases. Their research revealed how our bodies use regulatory T cells to keep the immune system in check.

Their work has launched a new field in peripheral tolerance research and led to the development of new medical treatments, including for cancer and autoimmune diseases.

New Treatment Coming for Stomach Cancer


An estimated 26,890 people in the U.S. were diagnosed with stomach cancer, and 10,880 died of the disease in 2024, according to the National Cancer Institute.

For many patients, by the time stomach cancer is diagnosed, it has already spread, or metastasized, throughout the abdomen. Newer chemotherapy and immunotherapy treatments have made it possible for patients with advanced stomach cancer to live for an average of 10 to 17 months after diagnosis.

The UT Dallas and UT Southwestern researchers hope their enhanced therapy can improve patients’ prognoses.

“There is a dire need for treatments to help people with advanced stomach cancer live longer,” Obaid said. “If successful, our approach ultimately can help patients with stomach cancer live longer after the cancer has spread.”

The approach uses lab-designed molecules and far-red or near-infrared light to “prime” the immune system to help it attack stubborn cancer cells, said Dr. Girgis Obaid, assistant professor of bioengineering in the Erik Jonsson School of Engineering and Computer Science.

Chinese Carbon Nanotube Insulator

 

Scientists are searching for new, advanced materials that can block heat while also being thin and lightweight. In a paper published in Advanced Functional Materials, Chinese researchers at Tsinghua University describe how they stacked and wound together very thin, flexible films of carbon nanotubes to create an insulation material called super-aligned carbon nanotube films (SACNT-SF). This revolutionary material blocks heat more effectively than any other known insulator at high temperatures.

The new carbon nanotube insulator can withstand high temperatures up to 2,600°C, outperforming all other materials used for extreme-temperature applications. This breakthrough could be used for heat shields on hypersonic vehicles and spacecraft during re-entry into the atmosphere and in other high-temperature environments.

In addition to its superior insulation, SACNT-SF is also remarkably durable. It can withstand repeated heating and cooling cycles and remains stable up to 3,000°C in an argon atmosphere. And unlike bulky insulation material, this innovative substance is made of paper-thin films that can easily bend around a variety of shapes.

Understanding "Culture"

 

The world of the early Hebrew.


Dr. Alice C. Linsley

A member has asked about the meaning of the term "culture", and she would like to know "what constitutes a culture?"

When we speak of a "culture" we must recognize that people adapt to the environment, which means that the culture will reflect its environment. Desert cultures around the world have much in common. River cultures around the world have much in common. Coastal populations share many common features. The same is true for the populations of the Artic. This is one of the more profound observations of Franz Boas, the American anthropologist, whose initial studies were done among the Eskimos.

Not surprisingly, the earliest human populations lived near major water sources such a rivers and lakes. Genesis describes Eden as a vast well-watered region extending from the Upper Nile to the Tigris and Euphrates. This is the region inhabited by the early Hebrew (4000-2000 BC) who dispersed into the areas shown on this map. The oldest known site of Horite Hebrew worship was at Nekhen on the Nile.



They traveled along the rivers that interconnected in Africa during the Africa Humid Period, also known as the African Aqualithic. The rock paintings that are found across what is today the Sahara reveal that the region was once green and watered. These images show people swimming and fishing.

Noah's homeland was in the region of Lake Chad about 6000 years ago. This is the only place on earth said to be Noah's homeland by the local populations. They call it Borno or Benue, both meaning "land of Noah". The local Kanari people call Lake Chad Buhar Nuhu, meaning "Sea of Noah". The now dry Sahara was much wetter then and the Chad Basin overflowed. Indeed, from Noah's perspective, all of his territory (eretz) would have appeared to be under water.

A distinctive trait of the Hebrew marriage and ascendancy pattern drove their dispersion. Hebrew sent-away sons were to move away from the Hebrew ruler's proper heir and establish territories of their own.

Noah was probably a sent-away son. His Hebrew ancestors likely lived in the Nile Valley. Some of those Hebrew ancestors may have been cave dwellers living along the Nile River.

His culture was that of the paleolakes of Africa. Archaeological research has identified various populations that lived at paleolakes near Noah's territory. See Paul Sereno's findings at Gobero

Paleolake populations were fishing and boating cultures. This Dufuna black mahogany boat was found in 1987 in Yobe State (Nigeria) buried 16 feet under clays and sands which alternating sequence showed evidence of deposition in standing and flowing water. The dugout is 8000 years old. By comparison, Egypt's oldest boat is 5000 years old.

Peter Breunig (University of Frankfurt) specializes in African archaeology. He has written this description of the Dufuna boat: “The bow and stern are both carefully worked to points, giving the boat a notably more elegant form”, compared to “the dugout made of conifer wood from Pesse in the Netherlands, whose blunt ends and thick sides seem crude”.

Breunig added, "Judging by stylistic sophistication, Breunig reasons that, “It is highly probable that the Dufuna boat does not represent the beginning of a tradition, but had already undergone a long development, and that the origins of water transport in Africa lie even further back in time.”
