Symposia 🔍

There will be 29 themed symposia and one open general symposium at the upcoming IPC7.

📢 Today we highlight:
✨Advances on the histology of the mineralised tissues of vertebrates✨

Cross-section images of the leg bone of an extinct flightless bird, with close-ups taken through a microscope.

Bone histology of phorusrhacids (terror birds) indicates rapid, uninterrupted growth (typical of most modern birds but unlike flightless paleognaths such as ostriches and kiwi): anatomypubs.onlinelibrary.wiley.com/doi/10.1002/... 🪶🧪 (📷Dreyer et al.)

Searching for dinosaur secrets in crocodile bones Until now, estimating how old a dinosaur was when it died has been a fairly simple process: Count up the growth rings in the fossilized bones. But new research into some of dinosaurs' living relatives...

Inferring bird migration from bone isotopes and histology: A fossil‐friendly methodological framework Bird seasonal migration is a remarkable biogeographic phenomenon, yet its deep-time origin(s) and evolutionary history remain poorly understood, with the bird fossil record largely overlooked. Thi...

Bone histology reveals life history and regional remodeling in black bears American black bears employ a dual skeletal strategy during hibernation: ribs remodel extensively, while femora maintain cortical strength to preserve locomotor capacity. This is the first comparativ...

New Publication Alert!

Experimental design. After 5 days of latency, all mice received a standard distraction protocol of 0.2 mm/12 h. In vivo micro-CT and histology were performed at different time points during the DO process, as indicated by arrows.

Distraction osteogenesis is used to treat limb length discrepancy and bone nonunion, deformities, and defects. Sishun Pu & coauthors developed a 4D time-lapse morphometry method to quantify bone formation and resorption: onlinelibrary.wiley.com/doi/10.1002/...

Our new paper in Bone Reports explores the potential of archaeological and palaeontological specimens to contribute to biomedical research and advance our understanding of bone remodelling processes, and further highlights avenues for future interdisciplinary collaboration in bone histology studies.

Figure showing osteocytes as drivers of bone remodelling.

In this Review, Silvia Marino & Teresita Bellido discuss the role of the parathyroid hormone 1 receptor pathway in bone homeostasis and of osteocytes as mechanosensors and drivers of bone remodelling (£) go.nature.com/43fzOI0

Bones Breathe Too: Why Indoor Air Quality Matters for Osteoporosis - AIR SUPPORT PROJECT New research shows that indoor air pollution—from cooking, gas stoves, wildfire smoke, and even traffic exhaust that seeps indoors—can accelerate bone loss and worsen osteoporosis.

Yesterday was World Osteoporosis Day, a reminder that bone health depends on more than calcium.

Polluted indoor air can weaken bones through inflammation and toxins.

Clean air may be one of the quiet protectors of strength as we age.

Brittle Bones Aren’t Just a Woman’s Problem — Pain News Network By Paula Span, KFF Health News Ronald Klein was biking around his neighborhood in North Wales, Pennsylvania, in 2006 and tried to jump a curb. “But I was going too slow — I didn’t have enough moment...

Osteoporosis is often seen as a disease that primarily affects older women. But older men can have brittle bones too, and lack of awareness and testing for osteoporosis can result in painful and life-threatening bone fractures. bit.ly/3WPsorn

Huge congratulations to our Honours student Bella Pearce, who submitted her Honours thesis today! Her thesis investigated femur intra-cortical bone remodelling variation with age and social status in a sample of medieval females.

Get your abstracts submitted! Our team has already done so and we look forward to going to Auckland for #ashb2025

We are pleased to offer Student Conference Support Grants for our 2025 meeting. If you are an ASHB student member and intend on presenting either a paper or poster, consider applying for financial support here: forms.gle/77WCN3ym3fGQ...

Applications close 11:59 NZDT on Monday 13th of October.

People who skip breakfast and eat late dinners may have an increased risk of developing osteoporosis, according to a new study published in the JES. Read more in @endocrinesociety.bsky.social: https://bit.ly/41WLdMg #JES #osteoporosis @endosocjournals.bsky.social

Back at the Aussie synchrotron @ansto.bsky.social scanning bone samples! So good to be back!!

Our lab member Holly Reid gave a presentation today at #WAC10 about distinguishing human from non human animal bone using histology

@isph2025.bsky.social Thanks to @justyna Miszkiewicz and team for a fabulous ISPH meeting! @paleohistology

New year, new social media platform, new destinations. More than excited to spend the week at the University of Queensland with Justyna Miszkiewicz, learning new cool things about human bone histology 🦴🔬

Don’t wait until menopause to strengthen your bones Screening for osteoporosis is recommended at age 65, but experts say women should be proactive about bone health long before that.

"Don’t wait until menopause to strengthen your bones. Bone density begins to decline in midlife, raising the risk of osteoporosis."
