Study reveals 93% of Australia's Indigenous population lost within 73 years of colonization

A Flinders University study estimates Australia's pre-colonial Indigenous population at approximately 2.22 million—potentially seven times higher than 1930s estimates of 250,000. The research found that 93% of this population was lost within 73 years of European arrival in 1788, representing a demog

Amyloid Removal in Alzheimer's Brain Shows Protective Effect on Tau

An autopsy study of an Alzheimer's patient revealed that brain regions successfully cleared of amyloid plaques showed little or no tau buildup, while neighboring amyloid-containing areas showed high tau levels and neurodegeneration. The findings suggest that removing amyloid plaques early may provid

Fungi networks maintain planetary health through nutrient trading and carbon sequestration

Mycorrhizal fungal networks in soil exchange nutrients with approximately 80% of Earth's plant species and sequester approximately 13 billion tons of atmospheric carbon dioxide annually—equivalent to roughly one-third of global fossil-fuel emissions. Despite lacking a brain, these fungi demonstrate

Arctic sea ice reaches troubling low in 2026

Arctic sea ice reached its annual minimum on September 12, 2026, covering approximately 4.6 million square kilometers, tying the 10th-lowest minimum in satellite records since 1978. Every summer from 2007 through 2026 ranks among the 20 lowest September extents, though the rate of summer loss has sl

Scientists Engineer New Fungal Defense to Protect Global Food Crops

Scientists at John Innes Centre and Kobe University engineered plant immune receptors capable of recognizing multiple fungal threats, targeting Magnaporthe oryzae which causes blast disease affecting rice, wheat, and barley. Rice blast destroys enough rice annually to feed approximately 60 million p

Brain Remains Active Under Anesthesia, Analyzing Language

Baylor researchers discovered that the human brain processes language and predicts upcoming words even under general anesthesia, challenging assumptions about consciousness. Using neural recordings from the hippocampus, they found neurons responding differently to unexpected sounds and demonstrating

Small Cancer Cells with Extra Chromosomes Show Higher Aggression

Virginia Tech researchers discovered that unusually small cancer cells carrying extra chromosomes grow faster, spread more readily, and resist common treatments. The five-year study involved creating tetraploid cancer cells with four complete chromosome sets and examining tumor behavior in mice.

Climate adaptation plans fail to translate into action across developing nations

While 143 of 154 developing countries have established National Adaptation Plan processes, implementation remains hampered by institutional capacity, climate finance availability, and project preparation gaps. The UN's Climate Promise: Forward initiative attempts to bridge these gaps through integra

Just transition to low-carbon economy requires more than financial support

An evidence review indicates equitable transition to a low-carbon economy requires more than financial assistance, as workers face job losses and carbon-dependent communities experience economic disruption. Just transition—ensuring no one is left behind in the shift to sustainable economies—requires

One-third of global food production lost or wasted; new approach to cut postharvest losses

About one-third of global food production is lost or wasted, a critical issue under UN Sustainable Development Goal 12.3, which targets halving food waste at retail and consumer levels by 2030. With global population projected to grow from 8.2 billion to 9.7 billion by 2050, reducing food loss and w

NASA develops batteries for lunar south pole operations in extreme cold

NASA researchers are developing batteries capable of functioning in the extreme cold of the moon's south pole to power lunar missions.

Wellcome Sanger Institute accelerates genome publication to 200 per month

The Tree of Life program at Wellcome Sanger Institute plans to increase monthly genome note publication from 30 to 200, advancing applications in agriculture, conservation, and medicine.
