Discovery of half-million-year-old wooden structure shows we"re wrong to underestimate our ancient relatives
To most people, complex technologies separate modern humans from their ancestors who lived in the Stone Age, thousands or hundreds of thousands of years ago. In today's fast changing world, older technologies, even those from a few years ago, are oft.....»»
Further evidence points to footprints in New Mexico being the oldest sign of humans in Americas
New research confirms that fossil human footprints in New Mexico are likely the oldest direct evidence of human presence in the Americas, a finding that upends what many archaeologists thought they knew about when our ancestors arrived in the New Wor.....»»
Feather-tailed possums in New Guinea were originally Aussies, according to fossil study
Analysis of Riversleigh fossils has revealed fascinating new facts about a tiny possum's ancestors. Scientists have long known that the miniature feather-tailed possums in Australia and the island of New Guinea—members of the marsupial family Acrob.....»»
New study shows signs of early creation of modern human identities
Early ancestors collected eye-catching shells that radically changed the way we looked at ourselves and others. A new study confirms previous scant evidence and supports a multistep evolutionary scenario for the culturalization of the human body......»»
Understanding the single cell proteome in the context of surrounding tissue
Similar to humans and animals, which adapt their diet or behavior to given environmental conditions, the function and protein composition of single cells also depends on which resources are available in their immediate environment......»»

Chinese astronauts may build a base inside a lunar lava tube
Caves were some of humanity's first shelters. Who knows what our distant ancestors were thinking as they sought refuge there, huddling and cooking meat over a fire, maybe drawing animals on the walls. Caves protected our ancient ancestors from the el.....»»
New origin story for key regulatory gene: PRC2 repressed jumping genes in ancestors of eukaryotes
The key protein complex PRC2 was discovered decades ago to silence genes, but new findings by Frederic Berger and his group at the Gregor Mendel Institute show that PRC2 represses transposons in a range of eukaryotes and only gradually evolved to sil.....»»
Grassland expansion was not a main driver of mammal evolution in Plio-Pleistocene Africa, research suggests
Mammal evolution in Africa, including that of modern human ancestors, through the late Cenozoic (Plio-Pleistocene, ~5.3 million years ago) may not have been driven by the expansion of grasslands as previously thought, new research has suggested......»»

The amount of imported products and meat in the Finnish diet has the most significant impact on global biodiversity loss
A recent study shows that the adverse impact of the current Finnish diet on biodiversity can be reduced by shifting to more plant-based diet. The impact of the current Finnish diet nearly exclusively comes from imported products when using life cycle.....»»
Skepticism about claim human ancestors nearly went extinct
Could the lives of the eight billion people currently on Earth have depended on the resilience of just 1,280 human ancestors who very nearly went extinct 900,000 years ago?.....»»
Early humans deliberately made mysterious stone "spheroids"
The early ancestors of humans deliberately made stones into spheres 1.4 million years ago, a study said on Wednesday, though what prehistoric people used the balls for remains a mystery......»»
Study suggests human shoulders and elbows first evolved as brakes for climbing apes
The rotating shoulders and extending elbows that allow humans to reach for a high shelf or toss a ball with friends may have first evolved as a natural braking system for our primate ancestors who simply needed to get out of trees without dying......»»
New analysis suggests human ancestors nearly died out
Study claims 99% of human ancestors died off 930,000 years ago. Enlarge (credit: Getty Images) Multiple lines of evidence indicate that modern humans evolved within the last 200,000 years and spread out of Africa startin.....»»
New fossil species suggests tropicbirds originated in Zealandia
A team of paleontologists from the University of Canterbury has discovered a remarkably intact fossil of one of the earliest ancestors of a group of birds now restricted to the tropics. Tropicbirds, now represented by only three living species, have.....»»
Using GPS, satellites and statistics to track and protect giraffes across a range of diverse African habitats
Nearly 6,000 years ago, our ancestors climbed arid rocky outcrops in what is now the Nigerian Sahara and carved spectacularly intricate, larger-than-life renditions of giraffes into the exposed sandstone. The remarkably detailed Dabous giraffe rock a.....»»
Liver-targeting drug delivered via nanogel carrier reverses obesity, lowers cholesterol in mice
A University of Massachusetts Amherst biomedical engineer has used a nanogel-based carrier designed in his lab to deliver a drug exclusively to the liver of obese mice, effectively reversing their diet-induced disease......»»
Yeast studies show that diet in early life may positively affect lifelong health
Researchers at the Babraham Institute are proposing an alternative link between diet and aging based on studies in yeast. Dr. Jon Houseley and his team's experiments show that healthy aging is achievable through dietary change without restriction by.....»»
New genetic analysis of Ötzi the Iceman yields some surprising findings
