- 1Climate crisis is affecting children's nutrition●Climate crisis is affecting children's nutrition https:// phys.org/news/2026-09-climate- crisis-affecting-children-nutri
A new report highlighted on Phys.org says the climate crisis is having a measurable impact on children's nutrition. Rising temperatures, extreme weather and disrupted food systems are reducing access to adequate diets for children, with the greatest harm falling on vulnerable communities. Discussion centers on the link between climate change, food security and child health.
- 2Indonesia fires threaten critically endangered orangutan, IUCN warns●Indonesia fires threaten critically endangered orangutan: IUCN https:// phys.org/news/2026-09-indonesi a-threaten-critic
The IUCN warns that ongoing fires in Indonesia are threatening the habitat of a critically endangered orangutan species, with burning forest destroying what remains of its already limited range. Conservationists say the blazes add to pressure from deforestation and palm oil expansion, and are urging stronger protection and firefighting measures before the species' population declines further.
- 3Computer scientist builds automated observatory to track satellites▼Computer scientist tracks satellites with automated observatory built from off-the-shelf technology
A computer scientist has built an automated observatory using off-the-shelf technology to track satellites in orbit. The project, reported by Phys.org, shows how affordable consumer hardware combined with custom software can take on work traditionally reserved for costly professional installations. The approach could make satellite tracking more accessible as concerns grow about congestion in low Earth orbit.

New analysis of particles from the Chernobyl exclusion zone shows that nuclear fuel remaining from the 1986 disaster is far more stable than scientists expected, even after nearly four decades of corrosion and radiation exposure. The findings offer fresh insight into how spent nuclear fuel degrades, with implications for long-term waste storage and reactor safety research worldwide.
- 5Diet alone cannot explain gut bacteria differences, study finds●Diet alone cannot explain differences in gut bacterial communities
New research reported by Phys.org indicates that diet alone cannot account for differences in people's gut bacterial communities, challenging a common assumption in nutrition science that what we eat primarily determines our microbiome. The findings suggest other factors, such as genetics, environment or lifestyle, play a significant role in shaping gut bacteria.
- 6Chip-based frequency combs bring portable atomic clocks closer▼New chip-based frequency combs demonstrate potential for portable atomic clocks
Researchers have demonstrated new chip-based frequency combs that show potential for use in portable atomic clocks. The advance points toward highly precise timekeeping devices small enough to move beyond laboratory settings, with possible applications in navigation, telecommunications and scientific measurement. Details of the demonstration were reported by Phys.org, though specifics about the team behind the work and performance figures were not provided.
