Body Donation in the Netherlands: A Guide to the Process

by Julia Evans – Entertainment Editor September 17, 2025
written by Julia Evans – Entertainment Editor

Joke Bruijs‘ Legacy: Donating Her⁢ Body to ⁢Medical Science – ​How it effectively works

Joke Bruijs has made the decision to donate her body‌ to science after her death, a selfless act that contributes to medical education and research. While registration for body donation‌ is currently​ paused at many Dutch ​university hospitals due ⁤to⁤ overwhelming demand,understanding the process is crucial for those considering this option. Here’s a breakdown of how⁤ body donation⁢ works in the Netherlands, based on information ‌from ‌ lichaamsdonatie.info and insights from Professor De Ruiter.

Currently, registration is temporarily suspended at⁤ institutions like⁢ the‍ Leidsch University medical Center (LUMC) ⁣due to “enormous interest,” with a recent pause⁤ lasting from October ‌31st last year to October 1st of ⁣this⁤ year. Individuals interested in registering are advised to contact the hospital in their ⁢region when registration⁣ reopens.

The process After‌ Death

Once a registered donor passes away, the body is typically transported⁤ to⁣ the Anatomy department⁣ within 24 hours.This rapid response is vital ​because, as Professor De ‍Ruiter⁤ explains, “The body will⁢ dissolve​ fairly quickly after the heart has stopped.” To preserve the body for educational ⁢and scientific purposes,⁢ embalming ⁢is performed. This involves injecting preserving agents and dyes into the bloodstream. Professor De Ruiter ⁤acknowledges this process ​limits the time for a customary physical goodbye.

How Donated ​bodies are Used

The⁣ majority of ⁣donated bodies are used for medical education, ⁢notably in‍ medicine and other biomedical training ⁣programs. ⁤Students utilize these ⁣bodies for studies of organs, tissue, and​ the nervous system, ‍and to practice surgical techniques. even after graduation, surgeons can use ​donated ⁤bodies to ⁢learn and refine new procedures.

Beyond education, donated bodies‍ are also invaluable for scientific research. Such as, Amsterdam UMC is currently conducting research into the body’s ⁤decomposition process, ‌burying bodies under ​various⁣ conditions to observe how they ⁣break ⁢down – a​ practice inspired by‍ “body farms” like those in Texas. ‍Donors can express‍ preferences ⁢regarding the ultimate use of their body,though Professor ​De Ruiter notes,”actually most people ⁤don’t demand that many demands.”

What Happens to ‍Remains?

Generally, remains are not returned‍ to relatives after‍ the ​completion of​ investigations.‌ However, academic hospitals maintain memorial ​places for donors, offering a space for remembrance. Annual survivor’s meetings, such as the one held in Leiden,‌ provide an opportunity⁢ to “remember‌ who they were.”

unlike organ​ donation, body ⁤donation is‍ typically‍ a whole-body commitment.⁣ While specific requests, such as prohibiting the publication ⁢of images, may be considered, its not possible to exclude ​certain parts of the⁣ body. Alternatively,individuals⁤ can choose to donate‌ only‌ the heart and/or brain to the Brain⁢ and Harmbank for⁢ dedicated scientific research.

The Value of⁣ Real Anatomy

Professor⁤ De Ruiter emphasizes ⁤the continued importance of ​studying real human‌ anatomy. “It’s great that⁢ you can study the ‌real anatomy at a remains,” ⁣he states. Doctors gain crucial insights into‌ the natural variations between ‌individuals, ⁣the⁣ feel‍ of tissues,⁢ potential ⁣for damage, and the ‍practicalities of surgical ​procedures. “We use this with great⁢ gratitude.”

Academic hospitals ⁣currently accepting body donations (as of the ⁤source material):

* ​ UMCG in Groningen
* LUMC in Leiden
* ‍ ‍ Radboudumc in Nijmegen
* Erasmus MC in Rotterdam
* UMCU in Utrecht
* ⁤ AZM in ⁣Maastricht
* ⁢Amsterdam⁢ UMC

written by Rachel Kim – Technology Editor

Perseverance​ Rover Investigates Potential Ancient Life Signs in Martian‍ Canyon

The Perseverance rover ⁣is currently exploring⁤ a region of Mars’ Jezero Crater, focusing on outcrops within the Neretva Vallis canal, specifically the Shining Angel and Masonic Temple areas, ⁢in search of evidence of past microbial life. scientists believe thes locations hold meaningful potential due to ‍their geological⁤ characteristics,‍ which suggest past interaction with water.

According to recent reports, the rover has been conducting ⁤investigations ⁣reminiscent of those carried out during the Bright Angel ⁢training exercises – likely ‌referring to ⁤simulations designed to prepare for analyzing ⁢complex geological⁣ formations. The primary target ⁢of interest ⁢is a sample collected from the ‍Sapphire ⁢Canyon area,located within the⁤ Beaver Falls work area alongside targets like Cheyava Falls,Apollo Temple,and Steamboat Mountain.

While initial assessments can be made using the rover’s ⁤onboard instruments, researchers emphasize​ that definitive analysis requires the sample to be returned to Earth.”we⁣ could create characteristics such as those we observe in the Bright Angel training,” stated ⁢a researcher,⁢ “But the ultimate tests can onyl be carried‌ out on the sample of the Canyon sapphire if it is brought back to Earth to be studied.”

The rover’s journey has taken it from the contact zone between the Margin and Neretva Vallis⁢ units, through the Bright Angel outcrop, ⁣and towards the Masonic Temple outcrop. The exploration is guided by orbital imagery⁢ and 360° mosaics, allowing scientists to map the terrain⁢ and⁢ identify key scientific targets. the Grapevine Canyon area is also nearby, downstream from the current work area.

This⁤ ongoing investigation represents a ⁣crucial step in the search for evidence of ancient life on Mars, ‍with‌ the collected‍ samples holding the key to unlocking the planet’s ⁢past.

Marine Ecosystem Resilience: A Surprise After Mass Extinction

by Rachel Kim – Technology Editor September 8, 2025
written by Rachel Kim – Technology Editor

A Resilient Ocean: New Insights⁣ into Mass Extinction Recovery

The Earth has experienced five major ​mass ‌extinction events, periods of catastrophic species loss driven by global ‌change. Scientists now ⁤believe we ⁢are on ⁣the precipice of a sixth. Understanding how ecosystems rebound from such devastation is therefore critical, and a recent study led by ⁤David Jablonski at⁤ the University of Chicago is challenging long-held assumptions about ⁣the ​recovery process following the most recent extinction ⁢- the end of the​ Cretaceous period.

This event, famous for wiping out the dinosaurs, eliminated over three-quarters of all species.⁣ Jablonski’s‍ team focused on marine mollusks – shellfish, ​oysters, ‍and others – due to⁤ the ⁤excellent fossil record provided ​by their durable shells. By ‌meticulously reconstructing the ecological landscape before the extinction and comparing it to the species present afterward, they uncovered a surprising result: despite‌ the massive loss ‍of ‌life, the fundamental ‌ecological structure of the marine environment remained remarkably intact.

“If 75% ‌of all‌ species are extinct, you would ‍expect that at least ⁣a few​ ways​ of life would⁢ be entirely lost, leaving​ only‌ one or⁤ two species to fill those⁣ roles,” explains Katie Collins of the London Natural History Museum. ‌”But that’s not what we see.”

This finding contradicts ‍previous theories about extinction recovery.⁢ For decades,​ some scientists⁢ believed⁢ mass extinctions ‌simply accelerated ⁢pre-existing evolutionary trends – dinosaurs were destined to ⁤be replaced by mammals,‍ and the asteroid impact merely sped ⁢up the ⁣process. Others proposed that extinctions acted as a selective pressure, favoring species capable of evolving⁤ to​ fill newly available⁣ niches.‍

Jablonski’s research doesn’t support either of these ideas. He ‍views the results​ as a warning,highlighting a gap in our understanding ‌of how‌ biodiversity ​loss impacts ecological function. “we do not understand how the loss of functional groups relates to the loss of biodiversity,” he states.

further complicating the picture, ‍the study revealed that the species which did ​ survive didn’t ‌necessarily thrive in a predictable manner. Contrary to expectations,survivors didn’t uniformly capitalize on opportunities and rapidly diversify. ⁤While this pattern ⁢might hold true for mammals, Jablonski ‌found it wasn’t the case in‌ marine ecosystems, with recovery appearing ⁤more random.

This ⁢research has meaningful implications for modern ocean conservation. ‌ With the‍ seas facing threats like acidification, pollution, ⁤and overfishing, understanding how ecosystems respond to large-scale disruption is paramount. ⁤Jablonski emphasizes the need to consider ⁤the broader ecological structure, not ⁤just individual species, when developing management policies and establishing marine reserves.⁤ ⁢”This is something we really ‍want to understand ⁤if ⁤we want⁢ to ⁣discuss ‍modern extinction and recovery in the ocean, as well as how to manage it,” he explains. “Billions of people depend on the sea for food, ​and we can see ‍that nature ⁤reserves and management policies need to consider⁤ the wider biota ecological ⁣structure, not just individual⁣ species.”

The study,published in Science Advances ​ on May ‌21,2025,is titled “The end-Cretaceous ⁢mass extinction restructured​ functional diversity but failed ⁤to configure the modern marine biota.”

Chinese Scientists Confirm Solid Core in Mars – New Planetary Insights

by Dr. Michael Lee – Health Editor September 6, 2025
written by Dr. Michael Lee – Health Editor

BREAKING: Chinese Scientists ⁤Confirm Solid Core on Mars, Revealing ⁢New Insights into Red Planet’s Structure

BEIJING – In a landmark finding, a team of Chinese scientists ‍has confirmed⁣ the existence of a solid inner core within Mars, providing crucial new data about the planet’s internal⁣ structure and evolution.The findings, based on seismic data collected by NASA’s InSight lander, represent the first definitive proof ⁣of a solid core on a planet other than⁢ Earth.

While scientists have long theorized about Mars’ core,conclusive evidence remained elusive. Humans first concluded the existence‌ of a core in the Earth in 1936 based on the analysis of seismic waves, but confirmation of its density wasn’t ⁤ascertained until the 1980s -‍ nearly half a century later.Research on Mars faced significant hurdles due too the limited availability of data. It wasn’t until 2018, with the deployment of a seismometer aboard the NASA‌ InSight ‌lander, that researchers began receiving data from martian earthquakes (Marsquakes).

Despite ‌recording ⁤over a thousand Marsquake events since 2018, analyzing the​ data proved challenging. Seismic signals were weak and frequently enough obscured by disturbances.Though, through‌ meticulous analysis of the InSight data, the team, led by Sun and⁣ Mao, successfully identified key seismic phases that‌ penetrate the Martian interior. These differing‍ wave properties revealed a layered core structure: a liquid outer core surrounding a solid inner core, where seismic waves propagate faster.

The research ⁣indicates the Martian core has a radius of approximately 600 kilometers, roughly one-fifth of ⁢the planet’s total radius. Notably, the proportion between the inner core and outer core of ⁤Mars is comparable to that of Earth, even when scaled to​ different planetary sizes.

Further analysis of⁤ the core’s chemical composition suggests it’s comprised primarily of iron and nickel, ‍alongside significant amounts of ⁣lighter elements -​ 12%-16% sulfur, 6%-9% oxygen, and up to 3.8% carbon. This high concentration of lighter elements offers new clues regarding the history of Mars’ magnetic field. ‌Early in its formation, Mars possessed a strong magnetic field, but this activity diminished and ultimately ​disappeared, a stark contrast to Earth’s ‍persistent global magnetic field.

“This discovery⁤ is an vital key because it is the first proof ‌of the existence of a core in a solid on planets other than the earth,” ⁢the report states. The findings confirm that Mars‍ underwent a‌ complex process of core and mantle differentiation, mirroring​ Earth’s⁣ geological evolution.

This success highlights the capabilities of Chinese scientists in interdisciplinary research, integrating geophysics, planetary⁢ science, and seismic data analysis, and underscores china’s growing international influence ⁤in space science.

Healthy Planetary Diet Linked to Lower Disease Risk and Improved Health

by Dr. Michael Lee – Health Editor September 5, 2025
written by Dr. Michael Lee – Health Editor

Planetary Health Diet Shows Promise, Comparable to Mediterranean Diet in Reducing Mortality

A growing body of research suggests a strong link between adopting diets focused on both human and planetary health and experiencing lower mortality rates. Teh “Planetary Health Diet” (PHD), developed in 2019 by an international panel of 37 experts convened by the Eat/Lancet commission, is gaining attention for its potential benefits, and recent studies are illuminating its impact.

The PHD emerged as a response to unsustainable consumption patterns that accelerated after World War II, marked by increased intensive breeding, industrial livestock farming, and the rise of ultra-processed foods. This shift dramatically increased meat and dairy consumption, particularly in Western nations, impacting both public health and the surroundings. The diet aims for a balance of human wellbeing and environmental sustainability, recommending a daily intake of 2,500 kilocalories with a limited intake of meat – only 30 kilocalories shoudl come from red meat and other meats excluding poultry, roughly equivalent to a small veal portion per week. Protein sources are primarily plant-based, including legumes, nuts, chicken, and fish.

while observational studies don’t prove direct causation, experts like José María Ordovás, director of Nutrition and Genomic at tufts University, acknowledge the PHD’s potential while noting limitations in generalizing findings across diverse populations.

Recent research conducted by Mercedes Sotos-Prieto, a nutritional epidemiologist at the Autonomous University of Madrid, further supports the PHD’s viability. A 14-year study, published in February and analyzing a cohort of Spanish patients, found that strong adherence to either the PHD or the Mediterranean diet was similarly associated with lower mortality from all causes and a reduced environmental impact. Sotos-prieto explains that the two diets share key characteristics, emphasizing a foundation of plant-based and whole foods. She suggests that in Mediterranean countries, where similar eating patterns are already culturally ingrained, transitioning to the PHD could be a natural and complementary process, allowing individuals to choose based on personal preference.

Interestingly, data from both American and English databases reveal a consistent profile of PHD adherents: they tend to be taller, predominantly female, have a lower body mass index, and possess higher levels of education and income. perhaps surprisingly, PHD followers also tend to consume more food overall. Unlike some other healthy diets, like the Mediterranean diet where greater adherence frequently enough correlates with lower calorie intake, the PHD appears to support healthy eating without inducing hunger, though researchers emphasize the need for further examination to confirm this observation.

Ancient Bacteria Reveal clues to Mammoth Extinction, Offer Hope for “De-Extinction” Efforts

By Rachel Kim, World-Today-News.com – June 27, 2024

For years, scientists have puzzled over the⁢ extinction ​of the mammoth – a creature that roamed ⁤the Earth alongside early human civilizations.‍ Now, a groundbreaking new study ⁣published today in Cell ‍ reveals a ⁤surprising piece of the puzzle: the ancient bacteria that lived within these colossal animals.

Researchers ⁣have successfully extracted and analyzed DNA from the microbiome of ‍mammoths dating back as far as ⁢1.1 million years,a feat pushing the ‌boundaries of ‍paleogenetic research. The analysis of 483 mammoth remains -​ primarily teeth, but also tusks and bones – uncovered genetic material from ​six groups of bacteria, some⁢ wiht‌ the potential to⁢ cause serious infections.This isn’t ⁣just ⁢a⁢ past curiosity.Understanding the relationship between mammoths and their microbiome ⁤could be key to unlocking the mystery of their extinction.Were these ancient creatures felled by internal infections? or‍ did ⁢their microbiome play⁢ a role ​in their adaptation to, ⁢and ⁢eventual⁣ inability to survive, a ​changing climate?

“This work opens ⁢a new chapter in our understanding of extinct species,” says lead researcher ‌Love Dalén, a leading expert in mammoth genetics. “Now we can not only
