Humans shape the journey of mud, study reveals
Mud can be surprisingly clear. A global team of scientists has uncovered a hidden truth: Human actions are shaping the journey of mud. Over the course of decades, our activities have wielded significant influence over the movement and dispersion of m.....»»
Researchers discover how we perceive bitter taste
Humans can sense five different tastes: sour, sweet, umami, bitter, and salty, using specialized sensors on our tongues called taste receptors. Other than allowing us to enjoy delicious foods, the sensation of taste allows us to determine the chemica.....»»
Study shedding new light on Earth"s global carbon cycle could help assess liveability of other planets
Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth—and it could help assess which other planets can develop life, ranging from plants to animals and humans......»»
Elon Musk’s Latest Mars Pitch Has Potential
SpaceX has made significant progress toward what once seemed an unattainable goal......»»
Humans have converted at least 250,000 acres of estuaries to cities and farms in last 35 years, study finds
Worldwide over the past 35 years, dams and land reclamation activities have converted 250,000 acres of estuary—an area roughly 17 times the size of Manhattan—to urban land or agricultural fields, with most land conversion and estuary loss in rapi.....»»
Archaeological study suggests cultural diversity increases biodiversity of ecosystems
Cultural diversity is likely to have an overall positive effect on the biodiversity of ecosystems. The homogenization of human life forms may therefore be regarded as an important motor of the ongoing major extinction events in the "Age of Humans" (A.....»»
Scientists discover new phage resistance mechanism in phage-bacterial arms race
One of the most abundant and deadliest organisms on Earth is a virus called a bacteriophage (phage). These predators have lethal precision against their targets—not humans, but bacteria. Different phages have evolved to target different bacteria an.....»»
Why is it so hard to drill off Earth?
Humans have been digging underground for millennia—on the Earth. It's where we extract some of our most valuable resources that have moved society forward. For example, there wouldn't have been a Bronze Age without tin and copper—both of which ar.....»»
Elon Musk just gave another Mars speech—this time the vision seems tangible
"These are unthinkable numbers, but we’re not breaking any physics to achieve this." Enlarge / SpaceX will continue to iterate on Starship. (credit: SpaceX) Elon Musk has been talking publicly about his sweeping vision.....»»
NASA knows what knocked Voyager 1 offline, but it will take a while to fix
"Engineers are optimistic they can find a way for the FDS to operate normally." Enlarge / A Voyager space probe in a clean room at the Jet Propulsion Laboratory in 1977. (credit: Space Frontiers/Archive Photos/Getty Images).....»»
eDNA methods give a real-time look at coral reef health
The human gut is full of microbes. Some microbes can make people sick, while others are responsible for balancing gut health. But humans aren't the only species whose health depends on these microorganisms. Coral reef ecosystems rely on microorganism.....»»
New research traces the fates of stars living near the Milky Way"s central black hole
Despite their ancient ages, some stars orbiting the Milky Way's central supermassive black hole appear deceptively youthful. But unlike humans, who might appear rejuvenated from a fresh round of collagen injections, these stars look young for a much.....»»
Mapping lava tubes on the moon and Mars from space
Sometimes, all you need for a new discovery is some creative math. That was the case for a new paper by Edward Williams and Laurent Montési of the University of Maryland's Department of Geology. They released a brief paper at the Lunar and Planetary.....»»
What"s the earliest the moon could have formed?
Astronomers are pretty sure they know where the moon came from. In the early solar system, a Mars-sized object dubbed Theia smashed into Earth. This cataclysmic collision knocked a huge mass of material into orbit, which coalesced and cooled into the.....»»
Mars may not have had liquid water long enough for life to form
Lab experiments suggest gullies on Mars might form when carbon dioxide heats up. Enlarge (credit: NASA/JPL-Caltech/University of Arizona) Mars has a history of liquid water on its surface, including lakes like the one th.....»»
Amphibians use scream inaudible to humans for self-defense against predators, study suggests
A study reported in the journal acta ethologica has recorded the use of ultrasound by amphibians for the first time in South America. It also describes the first documented case of the use of ultrasound for defense against predators, in a distress ca.....»»
The Anthropocene epoch that isn"t—what the decision not to label a new geological epoch means for Earth"s future
For almost 15 years, scientists have debated whether the Anthropocene should be an official geological epoch marking the profound influence of humans on the planet. Then in March, an international panel of scientists formally rejected the proposal fo.....»»
Attack and defense in the microverse: How small RNA molecules regulate viral infections of bacteria
Viruses need hosts. Whether it's measles, the flu or coronavirus, viral pathogens cannot multiply or infect other organisms without the assistance of their hosts' cellular infrastructure. However, humans are not the only ones affected by viruses: ani.....»»
Research shows animals can live alongside humans by being experts at judging risk
New research suggests animals can thrive in human-dominated environments by being expert judges of risk. Alexis Breen from the Max Planck Institute for Evolutionary Anthropology in Leipzig, and Dominik Deffner from the Max Planck Institute for Human.....»»
Temple bones in the skulls of dinosaurs and humans alike were formed by feeding habits, study suggests
Whether human or reptile, in the skull of most terrestrial vertebrates there is a gaping hole in the temple; in the case of most reptiles, there are two. Scientists have been looking for explanations for this for 150 years......»»
