Scientist Claims Alien Probes May Be In Plain Sight, Observing Earth's Growing Intelligence
Ellery suggested that building a nuclear reactor on the Moon could yield chemical signatures that could be explored in the future.

New Analysis Weakens Claims of Life on Distant Exoplanet K2-18b
A new study led by University of Chicago researchers has reanalyzed James Webb Space Telescope data and found weaker evidence for potential biosignatures on exoplanet K2-18b. Earlier reports had suggested the presence of dimethyl sulfide (DMS), a chemical associated with marine life on Earth. However, the latest analysis reveals that the signals ar...

Energy Signals From Milky Way's Core Could Unveil New Type Of Dark Matter: Study
A new study suggests that clues about dark matter may be hidden in the Milky Way's Central Molecular Zone, where unexplained chemical reactions could be caused by a lighter form of dark matter.

Spiders Detect Smells Through Leg Hairs, Claims New Study
Researchers have discovered that male spiders use specialised hairs on their legs, called wall-pore sensilla, to detect airborne scents, particularly pheromones released by females. These sensilla, mapped on the upper parts of the legs, allow males to locate mates through chemical signals with remarkable sensitivity. This discovery, observed in mal...

Do Atoms Really Touch? Science Explains Their Complex Interactions
The question of whether atoms ever truly "touch" depends on overlapping electron clouds rather than physical surfaces. According to Christopher Baird of West Texas A&M University, atomic "touching" is different from everyday physical contact. Atoms lack defined outer surfaces, and their interaction signals the start of physical effects like bonding...

A Whiff Of Tears Reduces Male Aggression: Study
Watching someone cry often evokes an emotional response -- but according to a new study published Thursday, human tears themselves contain a chemical signal that reduces brain activity linked to aggression.

Computers Can Detect Volcanic Eruptions, Chemical Blasts Using Artificial Explosion Signals, Study Claims
Computers could be trained using artificial explosion signals, to help them better detect distant nuclear detonations, chemical blasts and volcano eruptions. Infrasound is at a frequency too low to be heard by humans and travels farther than high-frequency audible waves. As explosions haven't occurred at every location on the planet and the atmosph...

"China Was Killing Us With Unfair Trade Deals," Says Donald Trump
U.S. President Donald Trump on Wednesday said his tough stance on China's economic and trade policies would ultimately benefit the American economy, even as Beijing signalled it could strike back by curbing sales of chemicals known as rare earths that are used in everything from iPhones to military equipment.

"Trump Hasn't Excluded Anything," US On Possible Strikes On Syria After New Chemical Attacks
President Donald Trump has not ruled out military action to stop chemical weapons attacks in Syria, senior administration officials said Thursday, signaling a intensified effort to press the Assad regime and its Russian patrons.

Dogs Detect Diabetes by Sniffing Warning Signs
A new study has found that dogs can be trained to spot the warning signs of diabetes in patients by sniffing a chemical found in our breath that signals dangerously-low blood sugar levels.

First Serotonin Neurons Made From Human Stem Cells
For the first time, researchers have used stem cells to create a specialised nerve cell that makes serotonin, a signalling chemical with a broad role in the brain.

The Deadly Healer: Spider Venom May Fight Chronic Pain
Scientists who analysed countless chemicals in spider venom say they have identified seven compounds that block a key step in the body's ability to pass pain signals to the brain.
