Study on tree rings shows how volcanic eruptions helped shape world history
A recent study suggests that volcanic activity may have played a bigger role in temperature fluctuations than scientists previously imagined. What’s more, these fluctuations appear to have contributed to the societal and economic conditions during the past 2,000 years, affecting civilizations and shaping world history as we know it. These are the findings of an international group […]

Are we under alien surveillance? Physicists say it’s a possibility
Aliens might have already found us, and they’ve been on the lookout ever since. American physicist James Benford proposes that alien “lurkers” may have set up probes on near-Earth objects (NEOs) that follow an orbital pattern similar to Earth. What’s more, these co-orbitals are very close to us, bound gravitationally not just to the sun but also the planet. But […]

Hunger makes you better: Neural circuits in the brain drive improved physical performance and heightens motivation
An international team of researchers identified the neural circuit that dictates whether you will persevere or give up. This neural circuit may be responsible for why people perform better when they are hungry. The researchers conducted their study using fruit flies and found a small region in their brains that became highly active when the flies were starved. “Our experiments show […]

Stunning NASA discoveries suggest Ceres is an ocean world percolating with briny waters from its interior
The National Aeronautics and Space Administration (NASA) has unveiled what it discovered about Ceres in a recent mission, shedding new light on the evolution of the dwarf planet and opening new curiosities. In 2016, NASA’s Dawn spacecraft went into an extended mission to probe Ceres, the biggest object in the asteroid belt and the only dwarf planet in the inner solar system. […]

Interplanetary hoppers: Microbes from Earth may have reached Venus by hitchhiking on asteroids
If Venusian life does exist, it may have originated from Earth: An interplanetary hopper hitched a ride with an asteroid that grazed Earth’s upper atmosphere and landed on Venus. Researchers from Harvard University — astronomy professor Avi Loeb and student Amir Siraj — proposed the idea after a group of scientists recently detected signatures of phosphine. Microorganisms can produce […]

Archaeologists uncover bizarre Germanic lord’s tomb circled with the graves of women who may be his concubines
An ancient tomb belonging to a Germanic lord from about 1,500 years ago has been unearthed in the German state of Saxony-Anhalt. The tomb was surrounded by six women believed to be the concubines of the lord, and speculation has it that they either sacrificed themselves or were slain for the burial. Researchers have yet […]

Heavy metal rain: Colossal “kilonova” explosions may be showering a nearby galaxy in gold and platinum
It’s not uncommon for cosmic objects such as stars to crash into each other. Such mergers generate massive explosions and send gravitational waves rippling through the cosmos. Mergers involving neutron stars are particularly strong. They result in a massive, turbocharged explosion called a kilonova that can be observed in nearly all space telescopes on Earth. An international […]

Three asteroids will barrel past Earth before September ends
Astronomers are closely monitoring three asteroids that will barrel past Earth before September closes. Two asteroids are set to blast past the planet within hours of each other on Sept. 25, according to the National Aeronautics and Space Administration (NASA) ’s Center for Near-Earth Object Studies. Meanwhile, an asteroid that could be as big as the Great Pyramid of Giza […]

New theory suggests how magnetars, a type of neutron star, can crack themselves open and send gamma-ray flares to Earth
Earth was pummeled by three separate series of intense gamma-ray flares in the last 40 years. While scientists agree that magnetars, a type of neutron star, were behind the flares, the mechanism that unleashed those waves of energy remains unknown. A recent study offers a compelling theory to what that mechanism is. Researchers from the University of […]

Forgotten dreams: REM sleep helps prevent information overload, explain scientists
Dreams are quickly forgotten the moment people wake up. This is likely due to a group of neurons that gets activated during rapid eye movement (REM) sleep – the phase of mammalian slumber when most dreams are made. A recent study published in the journal Science examined the neurons that produce appetite and sleep hormones in mice. Japanese and American […]
