Phys.org / Arabidopsis meristem map uncovers 18 cell clusters shaping stems and flowers
Researchers have produced the most detailed map yet of how stem cells in the growing tip of a plant begin their journey to form the many cell types that shape flowers and stems. They identified 18 distinct cell type clusters ...
Phys.org / Perfectly preserved pterosaur wing rewrites the fossil rulebook
An international study led by Curtin University has revealed new insights into how an ancient flying reptile was preserved in extraordinary detail for 113 million years, offering a rare glimpse into a vanished world.
Phys.org / Fossilized babies of ancient crocodile-like predators uproot understanding of how animals adapted to the land
Life on our planet began in the water. Eventually, one branch of the fish family tree developed legs and came up on land. These early four-legged animals, the tetrapods, were the forebears of today's mammals, birds, reptiles ...
Phys.org / 'Timescapes' may help explain how animal species perceive events so differently in time
There is evidence that nonhuman animals perceive the world, and how it unfolds in time, differently from humans and from each other. For example, certain beetles can see flickering in lights up to around 500 Hz, while in ...
Phys.org / Hidden electric space waves are quietly cleaning Earth's 'killer' electrons
High above our heads, a silent battle is unfolding within Earth's magnetic shield. For decades, scientists have tracked "killer electrons"—ultrafast particles capable of piercing satellite armor and endangering astronauts ...
Phys.org / Pigeons' eyes are almost perfectly still when they're flying, study finds
When pigeons are flying through the air, they lock their eyes in a near-fixed position instead of moving them around. Researchers from Harvard University discovered this after attaching a lightweight rig of cameras and mirrors ...
Phys.org / Ripple-like rings of the 'Bullseye galaxy' could be explained by dark matter
Two U.S. physicists have suggested that the nine concentric rings surrounding the galaxy LEDA 1313424, also known as the Bullseye galaxy, could have emerged through the quantum behavior of particles of dark matter. Through ...
Phys.org / Screens dominate the dinner table, with 77.6% of parents using devices
Food has always had a unique way of bringing people together. It becomes especially evident during family mealtimes, when children and adults gather around the table to share more than just a meal. They share stories, catch ...
Phys.org / Mars life search gets boost as rover test distinguishes mirrored biosignature molecules
Billions of years ago, environmental conditions on Mars were significantly more hospitable than they are today. Our neighboring planet was likely warm, humid and surrounded by a dense atmosphere. Whether simple microorganisms ...
Phys.org / Analysis of 352 probiotic supplements finds mismatched microbes across marketed health benefits
Probiotic supplements found in drugstores nationwide contain an assortment of microbes sold for specific health purposes despite limited understanding of the microbes' connections to their marketed use, new University of ...
Phys.org / Laser pulses set layered metals vibrating 1 trillion times per second, revealing electron-driven motion
How does light turn into motion within a metal? A team of researchers from European XFEL, the University of Potsdam and other participating institutions has shown that ultrashort optical laser pulses can trigger extremely ...
Phys.org / World's highest-consuming 10% cause up to $5.7 trillion a year in environmental damage, study finds
The environmental damage caused by the world's highest-consuming 10% of people is worth $1.7 trillion to $5.7 trillion a year. At the central and upper estimates, this is several times more than the international community ...
