Efforts to create a comprehensive map of all human cells have taken a significant leap forward. Researchers associated with the Human Cell Atlas (HCA), a global scientific consortium, have released over 40 studies detailing critical progress in mapping the 37 trillion cells that make up the human body. These findings, published on 20 November in Nature journals, focus on cells in organs such as the lungs, skin, and brain and outline advanced computational tools for analysing vast datasets.

The project aims to profile cells from diverse populations worldwide to identify their unique functions, locations, and interactions at various stages of life. Already, data from 100 million cells sourced from over 10,000 individuals in more than 100 countries have been collected. By 2026, researchers plan to present the first draft of the atlas, with future versions expected to incorporate billions of cells.

Detailed Discoveries Across the Body

Among the recent findings is a comprehensive cellular map of the digestive system, from the oesophagus to the colon. This work, based on data from 190 individuals, uncovered a type of cell involved in inflammatory diseases like Crohn’s disease and ulcerative colitis. Professor Itai Yanai of NYU Langone Health noted that these cells likely trigger immune responses, contributing to inflammation in diseased tissues.

Other studies have shed light on early human development, including insights into skeletal formation during pregnancy and conditions like craniosynostosis. Maps comparing fetal brain development with lab-grown brain organoids also highlight the accuracy of these models, which replicate human brain activity up to the second trimester.

Implications for Medical Research

The findings have implications for drug discovery and disease understanding. Dr Aviv Regev, co-chair of the HCA, likened the work to advancements in mapping technologies, stating, “We have transitioned from basic, crude maps to something as detailed as Google Maps.” However, she acknowledged the significant work that lies ahead to complete this ambitious project.

The research has already led to groundbreaking discoveries, including the identification of a new lung cell type and insights into tissues vulnerable to COVID-19. Scientists aim to continue refining these maps, using organoids and other methods to unravel human biology and disease mechanisms.

1,000-Year-Old Mummy Found by Gas Workers in Peru Linked to Chancay Culture

The gas workers in Peru discovered a mummy dated to a thousand years old during the time of pipe installation in Lima. The company named Calidda said this and confirmed this latest discovery of the prehistoric tomb in Peru. The workers found a trunk of the huarango tree, which is an inheritance of Peru’s coastal region. It served as a tomb marker in history and has a depth of 20 inches, as reported by the archaeologist Jesus Bahamonde to the gas company Calidda.

Archaeological Dig Found Mummy

Calidda also employed several archaeologists to get the excavation done at a deeper level in search of a heritage site in Lima. Archaeologist Jesus Bahamonde said that they found the mummy of a boy aged between 10 to 15, at a depth of 1.2 meters. The way of burial and the objects signaled its development between 1000 and 1200, he said. The mummy was found in a sitting position with the arms and legs bent, as per Bahamonde. They were shrouded and were found with the calabash gourds.

Mummy Belongs to the Pre-Inca Chancay Culture

Along with mummy, there were ceramic objects, such as plates, jugs, and bottles were found which were decorated with fishermen and geometric figures. This style of burial is similar to that of the Pre-Inca Chancay culture between the 11th and 15th centuries.

How they were found

The incident of digging took place when the gas workers were unearthing from an avenue in the district, Puente, located in northern Lima. In Peru, it is a must for the utility companies to hire archaeologists while drilling the Earth. This is because there is a possibility of getting any heritage sites.

Lima, A Place of Archaeological Sites

Till now, Calidda has made over 2,200 archaeological findings from the year 2004. Lima is home to over 500 archaeological sites, including 12 huacas, which are ancient cemeteries termed in the Indigenous Quechua language.

Radio Signal from Early Universe May Reveal the Masses of the First Stars

Radio Signal from Early Universe May Reveal the Masses of the First Stars

A faint radio signal beamed over the eons by hydrogen atoms in the early universe that contains important information about the mass and nature of the first stars. The finding is made by researchers, including those from the University of Cambridge, using a new model that for the first time investigates the effects of early starlight, which is produced by the first generation of stars, and the impact of the first supernovae on the 21-centimetre line from hydrogen. The finding gives us a new approach to learn about the Cosmic Dawn, a time when the cosmos changed from dark to light through the formation of stars and galaxies.

Early Universe’s Radio Signal Reveals Mass of First Stars, Say REACH and SKA Researchers

According to a report in Nature Astronomy, the team—including Professor Anastasia Fialkov from Cambridge’s Institute of Astronomy—demonstrated that the 21-cm signal, originating just 100 million years after the Big Bang, is sensitive to the masses of the first stars. These Population III stars are thought to be vastly different from stars today, and their influence on hydrogen gas could be tracked through radio observations. The work was conducted under the REACH project and contributes to the upcoming Square Kilometre Array (SKA).

Instead of visual observation like that performed by the James Webb Space Telescope, the REACH and SKA instruments collect statistical data about cosmic radio waves. In addition, they considered the impact of ultraviolet light and X-rays — produced by X-ray binary systems — on the 21-cm signal. They discovered that the impact of these factors on early cosmic rays had been underestimated in earlier studies, especially for what happens when collapsed stars interact with surviving stars in binary systems.

Though still in its calibration phase, REACH is already offering insights into the universe’s first billion years. Fialkov and her team think the technique might eventually determine not only when stars were forming but also how massive they were. “The outcomes of this project will define the future of radio astronomy, including site involvement from places such as the Karoo (South Africa),” explains Dr Eloy De Lera Acedo, REACH principal investigator.

These findings are a significant step toward understanding how the first objects in the universe developed from darkness to a galaxy.

Ancient Tel Dan Temple Reveals Centuries-Old Phoenician Ritual Bathing Traditions

A new archaeological find proves that ritual cleansing was a component of religious practice at an ancient sanctuary in northern Israel in the time of the kingdom of Israel. The sanctuary was equipped with a unique bathhouse, thought to have been used by the priests for ritual bathing. There, the diggers discovered two spaces — one room with yellow plaster, which had a dressing area, and another with walls of blue plaster and a basin — that offer a rare glimpse into how water was used in rituals of sacred purification. The discovery adds new depth to understanding Near Eastern religious practices linked to city-based deity worship.

Ancient Tel Dan Sanctuary Reveals Ritual Bathing Traditions Linked to Mysterious Deity Worship

According to a report published in Levant by Dr. Levana Tsfania-Zias, the sanctuary included a modest two-part bathing unit—featuring a yellow-plastered dressing room and a blue-plastered basin—suggesting ritual use by the priestly class. Unlike full-immersion baths, and because it is not heated, the basin’s size means worshippers might have washed themselves while standing, with cold spring water that flows into the Jordan from outlets nearby.

The first temple, constructed on a Middle Bronze Age rampart, had a tripartite plan of porch, cella, and adyton. A limestone fragment with inscriptions in both Greek and Aramaic, discovered in 1976, names an obscure deity and was almost certainly invoked in the central sanctuary of Dan. Scholars believe the deity’s identity remains uncertain due to the regional naming customs of ancient Near Eastern cities.

Following the destruction of the first temple by the Seleucids, a new temple was erected in its place, which preserved the bathing. After a 2-century gap, the site re-emerged in the Middle–Late Roman period for new purposes. Pilgrims were cleansed in a Fountain House, using primitive clay vessels that were likely smashed after use — a process mirrored in biblical texts describing ritual purity.

As so much of the sanctuary at Tel Dan remains in question, the scholars emphasised the significance of the site for the region. Dr. Tsfania-Zias believes the site would have been an attraction for both locals and visitors, something reinforced by imported ceramics and multilingual inscriptions that hint at a wider spiritual attraction. Deeper excavations could yet reveal what other deity or practices characterised this sacred spot in ancient times.
