A new study reveals that extinction rates for plants, arthropods and land vertebrates peaked about 100 years ago and have since declined. Researchers analysed 912 species and found the most recent surge of extinctions occurred on islands and under drivers quite different from today’s threats.

Viwango vya kutoweka kwa mimea na wanyama vinaanza kupungua

UNIVERSITY OF ARIZONA

Utafiti mpya unaonyesha kwamba viwango vya kutoweka kwa mimea, arthropoda na wanyama wa ardhini vilifikia kilele takriban miaka 100 iliyopita na tangu wakati huo vimekuwa vikishuka. Uchambuzi wa spishi 912 unaonyesha kuwa sehemu kubwa ya kutoweka ilikuwa kwenye visiwa na kutokana na sababu tofauti na vitisho vya sasa.

A recent Carbon Brief study shows China’s carbon dioxide emissions have remained unchanged or declined for 18 straight months, thanks in part to a surge in solar (+240 GW) and wind (+61 GW) capacity and a 5% drop in transport emissions.

Scientists at TU Wien have developed a non-toxic “deep-eutectic” solvent that separates blended fabrics — like cotton-polyester mixes — within minutes. Cotton stays intact and polyester is recovered almost fully, offering a near-complete recycling method for textiles that were once nearly impossible to reclaim.

Researchers at the University of Cologne have discovered a powerful antibody — 04_A06 — that neutralizes around 98.5 % of over 300 tested HIV strains. In lab experiments the antibody reduced viral load to undetectable levels — a major step toward broad-spectrum therapies for prevention and treatment worldwide.
