1.5 Million-Year-Old Prints

Footprints from two different human ancestor species, dating back 1.5 million years, have been discovered near Lake Turkana, Kenya. This groundbreaking find represents the first fossil evidence of such coexistence, with the tracks of Homo erectus and Paranthropus boisei likely made within hours of each other. The discovery sheds light on how early humans shared environments and potentially competed for resources or avoided predators.

The study, published in Science, employed advanced 3D analysis to differentiate between the footprints. Rutgers University geologist Craig Feibel, a co-author, identified the prints' formation on soft sediment at the lake's edge. Lead author Kevin Hatala, a Chatham University biology professor, highlighted the unique behavioral insights footprints provide, offering a perspective not possible with skeletal remains or tools. This discovery affirms that multiple hominin species coexisted during the Pleistocene Epoch, navigating shared landscapes with shared traits like bipedalism.

The coexistence of these species raises intriguing questions about their interactions, such as cultural exchanges or reproductive behaviors. While Homo erectus thrived for over a million years, Paranthropus boisei disappeared after a few hundred thousand years. As "trace fossils," the footprints offer rare behavioral evidence, advancing our understanding of human evolution. "This is the first clear proof of two hominin species walking the same ground at the same time," Feibel remarked, calling it a vital step in unraveling humanity's ancient past.

Compostable Plant Pots

A New Zealand-based startup, Compostify, has unveiled a groundbreaking biodegradable alternative to single-use plastic, specifically targeting the garden nursery industry. After five years of rigorous research, the company is poised to replace the 350 million plastic pots produced annually in New Zealand with bioplastic containers that naturally decompose in soil. Co-founder and CEO Peter Wilson emphasized the mission to harmonize with nature, stating, “Our bioplastic is durable, practical, and decomposes naturally, enriching the soil instead of polluting it.”

Compostify's innovative pots, crafted from sustainable crops like sugarcane, cassava, and corn, are designed to last up to 12 months above ground before breaking down in soil, where they act as a natural fertilizer. Unlike traditional bioplastics that can leave microplastic residues, Compostify's material decomposes completely, leaving no toxins behind. With support from Crown Research Institute Scion, the product combines biopolymers from renewable sources with organic bio-fillers sourced locally. Originally developed under the name PolBionix, the product has been rebranded as Compostify for its national launch.

Looking ahead, Compostify plans to expand its eco-friendly solutions to other industries, starting with biodegradable rebar safety caps for construction. These caps aim to replace conventional plastic versions that often contribute to waste. "Our bioplastic paves the way for a future without single-use plastics,” said Wilson. “We aim to help our partners, both in New Zealand and globally, reimagine waste management.” Compostify’s products are home-compostable, decomposing within 12 months in compost and up to 24 months in soil—marking a significant step forward in sustainable waste management.

Daring Duo

British adventurers Ross and Hugo Turner, known as the Turner Twins, have achieved another remarkable milestone by flying a tandem electric paramotor 8,000 feet above the French Alps. Soaring 2,438 meters in a custom-built aircraft, their accomplishment has been submitted to the World Air Sports Federation (FAI) for official recognition. The Devon-based twins, already world record holders as the first siblings to row across the Atlantic Ocean, spent months awaiting perfect weather for their latest challenge. “The conditions were perfect, and the flight went smoother than expected,” Hugo Turner shared, highlighting the unexpectedly efficient battery performance in the cold alpine air.

The flight was not without skepticism. According to Ross Turner, their official observer doubted the electric battery’s capability to sustain the journey, saying they wouldn’t have enough power. Yet the brothers defied expectations, solidifying their reputation as boundary-pushing explorers. Their drive for adventure is rooted in personal resilience; a near-paralysis Hugo experienced at 17 following a car accident inspired the duo to embrace life’s challenges and tackle them together. Over the years, they have set records and explored uncharted territories, from rowing the Atlantic in 41 days as the youngest crew to cycling across continents and trekking through extreme environments.

Beyond their paramotor triumph, the Turner Twins have continually used their expeditions to test emerging technologies. From hiking in Greenland and Iceland with historical polar explorer gear to completing a 10,000-mile electric road trip from London to China, their projects combine adventure with innovation. With each feat, they aim to inspire others while pushing the limits of human potential and sustainable exploration.
