Archaeology: Occupational hazards for ancient Egyptian scribes

2024-06-27
(Press-News.org) Repetitive tasks carried out by ancient Egyptian scribes — high status men with the ability to write who performed administrative tasks — and the positions they sat in while working may have led to degenerative skeletal changes, according to a study published in Scientific Reports.

Petra Brukner Havelková and colleagues examined the skeletal remains of 69 adult males — 30 of whom were scribes — who were buried in the necropolis at Abusir, Egypt between 2700 and 2180 BCE. They identified degenerative joint changes that were more common among scribes compared to men with other occupations. These were in the joints connecting the lower jaw to the skull, the right collarbone, the top of the right humerus (where it meets the shoulder), the first metacarpal bone in the right thumb, the bottom of the thigh (where it meets the knee), and throughout the spine, but particularly at the top. The authors also identified bone changes that could be indicative of physical stress caused by repeated use in the humerus and left hip bone, which were more common among scribes than men with other occupations. Other skeletal features that were more common among scribes were an indentation on both kneecaps and a flattened surface on a bone in the lower part of the right ankle.

The authors suggest that the degenerative changes observed in the spines and shoulders of scribes could result from them sitting for prolonged periods in a cross-legged position with the head bent forwards, the spine flexed, and their arms unsupported. However, changes to knees, hips, and ankles could indicate that scribes may have preferred to sit with the left leg in a kneeling or cross-legged position and the right leg bent with the knee pointing upwards (in a squatting or crouching position). The authors note that statues and wall decorations in tombs have depicted scribes sitting in both positions, in addition to standing, while working. Degeneration to the jaw joints could have resulted from scribes chewing the ends of rush stems to form brush-like heads they could write with, while degeneration to the right thumb could have been caused by repeatedly pinching their pens.

The findings provide greater insight into the lives of scribes in ancient Egypt during the third millennium BCE.

To protect corals from summer heatwaves, we should help their microbial symbionts evolve heat tolerance in the lab, researchers say

2024-06-27
Most coral reef restoration efforts involve restocking reefs with nursery-grown corals. However, if these corals are of the same stock as their wild counterparts, they will be equally vulnerable to the heat stress that caused the bleaching event in the first place. In a review publishing June 27 in the journal Trends in Microbiology, researchers discuss the potential of improving corals’ chances by inducing the evolution of heat tolerance in their symbionts—the mutualistic microbes that provide corals with nutrients in ...

Geographic disparities in head and neck cancer mortality and place of death

2024-06-27
About The Study: Rural residents with head and neck cancer experienced higher mortality rates and less annual improvement compared to urban counterparts in this cross-sectional study. Multilevel barriers may explain the widening rural-urban mortality gap, including alcohol and tobacco use and lower human papillomavirus (HPV) vaccination rates.

The mechanism behind melanoma resistance to treatment

2024-06-27
In many cases of malignant melanoma, the effect of targeted treatment is lost over time. A research team from UZH and USZ has now discovered that a factor secreted by tumor cells is responsible for the resistance. These findings could pave the way for more effective therapies.   Malignant melanoma is one of the most aggressive types of cancer. Despite recent progress in effective therapies, the tumors of many patients are either resistant from the outset or become so during the course of treatment. “It is therefore crucial to understand the mechanism ...

Research shows how common plastics could passively cool and heat buildings with the seasons
2024-06-27
Researchers at Princeton and UCLA have developed a passive mechanism to cool buildings in the summer and warm them in the winter. In an article published June 27 in the journal Cell Reports Physical Science, they report that by restricting radiant heat flows between buildings and their environment to specific wavelengths, coatings engineered from common materials can achieve energy savings and thermal comfort that goes beyond what traditional building envelopes can achieve. “With the increase ...

Study supports precision radiation therapy in lung cancer
2024-06-27
HOUSTON ― Results from a new study led by researchers at The University of Texas MD Anderson Cancer Center support standard use of the more precise intensity-modulated radiotherapy (IMRT) over the alternative 3D-conformal radiotherapy (3D-CRT) for patients with unresectable, locally advanced non-small cell lung cancer (NSCLC). The study, published today in JAMA Oncology, revealed fewer side effects with IMRT, with similar survival outcomes. A prospective secondary analysis of long-term outcomes from 483 patients on the Phase III NRG Oncology-RTOG 0617 randomized trial demonstrated ...

These mushrooms have “massively expanded” genomes to make them more adaptable to multiple lifestyles

These mushrooms have “massively expanded” genomes to make them more adaptable to multiple lifestyles
2024-06-27
A study of multiple Mycena mushroom species reported in the journal Cell Genomics has found that they have unexpectedly large genomes. While the mushrooms had been thought to be purely saprotrophic – living by degrading dead organic material alone – the discovery suggests that they may instead have a collection of genes to enable them to adapt to different lifestyles as circumstances change. Interestingly, they show certain Mycena strains living in the Arctic have some of the largest mushroom genomes ever described.   These mushrooms show widespread growth across their genome. This includes not only the genes that help them invade or interact ...

The European Southern Observatory’s Extremely Large Telescope (ESO’s ELT), under construction in the Chilean Atacama Desert, is one step closer to completion. German company SCHOTT has successfully cast the blank for the last of the 949 segments commissioned for the telescope’s primary mirror (M1). With a diameter of more than 39 metres, M1 will be by far the largest mirror ever made for a telescope. Too large to be made from a single piece of glass, M1 will consist of 798 hexagonal segments, each about five centimetres thick and 1.5 ...
