Today, the Sahara Desert is a sea of sand, but 7000 years ago it was a lush savanna full of hippos, crocodiles, elephants, and giraffes. During a humid, monsoon-heavy interval that spanned more than 5 millennia, people hunted, fished, and eventually herded livestock in a landscape now covered by shifting dunes. The findings are reported in a paper this week in Nature.

Kwesia X grew up in south east London, surrounded by busy roads and tower blocks. When faced with tragedy and homelessness, she turned to nature to find peace. Now she’s working hard to bring the experience of the natural world to young people in the city, and they’re often amazed by the plants and creatures living in the concrete jungle. You can find her videos on her YouTube channel, City Girl in Nature.

A new study reveals plants, fungi, bacteria, protists, and even some viruses deploy venom-like mechanisms, similar to that of venomous snakes, scorpions and spiders, according to researchers at Loma Linda University School of Medicine. The study is published in the journal Toxins.

A team of botanists with members from Muse–Museo delle Scienze, Udzungwa Corridor LTD, Via Grazia Deledda and the National Museum of Kenya has discovered a new species of tree growing in the mountainous rain forests of Tanzania. In their paper published in the journal Phytotaxa, the group describes how and where the tree was found and its characteristics.

Near the local storefronts lies the site of an excavation that unearthed stone tools from 150,000 years ago—the earliest sign ever of humans inhabiting a tropical forest…”The results represent the oldest yet known clear association between humans and this habitat type,” they wrote in their paper, published in the journal Nature last month after years of research.

Fossils found in China’s Turpan-Hami Basin reveal a refuge, or “life oasis”, for plants and animals during the Permian extinction – the worst mass extinction in Earth’s history. The fossils are detailed in a paper published in the journal Science Advances.

A stressful life can leave marks on our genetic code, some of which can even be passed on to our children. A study now reveals how the biological impact of trauma on a mother persists long after the violent acts themselves have passed.

Water may have first formed 100–200 million years after the Big Bang, according to a modeling paper published in Nature Astronomy. The authors suggest that the formation of water may have occurred in the universe earlier than previously thought and may have been a key constituent of the first galaxies.

New research has demonstrated the precise relationship between past ice ages and each wobble, tilt, and angle of the planet’s path, unlocking a new tool for predicting the future fluctuations of our global climate. The team’s research has been published in Science.

The earliest evidence that humans inhabited rainforests has been found in Africa, a surprising find which pushes human settlement in these habitats much further back than previously thought…As a result, rainforests have often been overlooked as important habitats in the evolution of early modern humans. New research published in Nature has put a dent in this assumption.

A very rare treat is about to grace Earth’s night skies. On the evening of 28 February 2025, all seven of the other planets in the Solar System will appear in the night sky at the same time, with Saturn, Mercury, Neptune, Venus, Uranus, Jupiter, and Mars all lining up in a neat row – a magnificent sky feast for the eyes known as a great planetary alignment.

In a rare encounter, a young man from an isolated Indigenous tribe approached a riverine community in Brazil’s Amazon, the country’s Indigenous affairs agency and local witnesses said Thursday.

Advanced artificial intelligence is to revolutionise fundamental physics and could open a window on to the fate of the universe, according to Cern’s next director general.

Scientists have found all five nucelobases alongisde minerals essential for life as we know it on the potentially hazardous asteroid Bennu. The two teams of researchers who made the discoveries published their findings Jan. 29 in two papers in the journal Nature Astronomy.

The focus of the prospecting campaign was on an area that during the Pleistocene housed a large lake, now completely dried up, with ancient wadis or dry riverbeds crossing the landscape. Egberts collected over 850 artifacts, ranging from very old hand axes from the Early or Old Paleolithic to Levallois reduction flakes from the Middle Paleolithic, all surface material.

A review of the oldest known dinosaurs has revealed that fossil evidence for their origin probably has not yet been discovered. Most of the earliest dinosaur fossils have been found in South America and Africa.
