Brain size riddle solved as humans exceed evolutionary trend
The largest animals do not have proportionally bigger brains—with humans bucking this trend—a study published in Nature Ecology & Evolution has revealed......»»
A rare Venus solar transit helps unravel exoplanet atmospheres
In the next decade, researchers will start probing the atmosphere of planets as small as Earth and Venus orbiting nearby stars. But although these two solar system planets are similar in size and bulk density—so that some call them "twins"—their.....»»
Biologist explores why humans have sex—and sexes—in a world where life requires neither
University of Maryland biology Professor Eric Haag has spent his career studying animal reproduction, but people's sex lives never factored into his research. That changed in 2014 when a cancer diagnosis prompted Haag to take stock of his career......»»
Isotope analysis reveals mammoth as key food source for ancient Americans
Scientists have uncovered the first direct evidence that ancient Americans relied primarily on mammoth and other large animals for food. Their research sheds new light on both the rapid expansion of humans throughout the Americas and the extinction o.....»»
Archaeological remains in Alaska show humans and dogs bonded 12,000 years ago
"Dog is man's best friend" may be an ancient cliché, but when that friendship began is a longstanding question among scientists. A study led by a University of Arizona researcher is one step closer to an answer to how Indigenous people in the Americ.....»»
Your Verizon bill is getting a bit more expensive
Your Verizon bill is going up. This size of the increase depends on how many lines you have......»»
Two reasons to suggest the iPhone 17 may have Face ID embedded in the display
Apple has been granted another patent for technology that would allow it to have Face ID embedded in the display, enabling the company to reduce the size of the camera cutout. While Apple has been working on this for many years, there are a couple.....»»
HowStuffWorks founder Marshall Brain sent final email before sudden death
Popular tech educator died in his office within hours of claiming retaliation for filing NCSU ethics reports. The week before Thanksgiving, Marshall Brain sent a final email to hi.....»»
Neanderthals were making hand stencil rock art more than 66,000 years ago, U-series dating suggests
A discovery deep within a cave in Spain has challenged the history of human artistic expression. Researchers have determined that hand stencils in Maltravieso Cave are more than 66,000 years old, suggesting that Neanderthals, not modern humans, were.....»»
Caving expedition yields valuable insight into cognitive performance under stress
Lab-based research is a bedrock of how modern science is practiced, but it cannot account for most experiences humans encounter outside the lab. Likewise, most of these experiences cannot be replicated in a lab setting......»»
Simulated outbreaks demonstrate how evolutionary approaches can estimate the speed of viral spread
Evaluating the speed at which viruses spread and transmit across host populations is critical to mitigating disease outbreaks. A study published December 3 in PLOS Biology by Simon Dellicour at the University of Brussels (ULB), Belgium, and colleague.....»»
Enzyme study sheds light on the molecular mechanism behind "sleepiness"
Recent research has observed that chemical modifications called phosphorylation of proteins in brain neurons dynamically regulate sleep and wakefulness. But the protein kinases that suppress sleep and the dephosphorylation enzymes that control sleep.....»»
Mid-Pleistocene climate change may have shaped hominin development and dispersal
A multi-institutional team of evolutionary specialists, climatologists and sociologists has found evidence that climate change during and after the Mid-Pleistocene likely shaped hominin development in parts of what is now Asia......»»
How did human brains get so big? The answer could be in our gut
Brain tissue is among the most energetically costly in the body, and as a result, larger-brained mammals require more energy to support brain growth and maintenance. Exactly which biological changes allowed human ancestors to meet the very high needs.....»»
Deep-sea marvels: How anglerfish defy evolutionary expectations
A Rice University study sheds light on the extraordinary evolution of anglerfish, a group of deep-sea dwellers whose bizarre adaptations have captivated scientists and the public alike. The research, published in Nature Ecology & Evolution, uncovers.....»»
Seeing is believing: Leveraging defining morphological features for accurate selection of brain organoids
By combining morphological and single-cell level gene expression analyses, a team of researchers led by Professor Jun Takahashi in the Department of Clinical Application at Kyoto University has established a new non-destructive system to select high-.....»»
Largest oxygen-poor region of ocean is more variable than previously thought
Analysis of nitrogen isotope ratio in coral skeletons shows strong decadal oscillations in the size of the world's largest oxygen-deficient zone (ODZ) over the last 80 years. These findings imply that this ODZ is more dynamic than previously thought.....»»
How I turned the M4 Mac mini into a travel computer
People have been loving the all-new M4 Mac mini since it was released last month. The combination of power, price, and new smaller form factor has people drooling over what is possible. But for me, the best part was the new size. This had me thinking.....»»
Muddy footprints suggest 2 species of early humans were neighbors in Kenya 1.5 million years ago
Muddy footprints left on a Kenyan lakeside suggest two of our early human ancestors were nearby neighbors some 1.5 million years ago......»»
