Black holes form natural time machines that allow travel to both the past and the future. But don’t expect to be heading back to visit the dinosaurs any time soon. At present, we don’t have spacecraft that could get us anywhere near a black hole. But, even leaving that small detail aside, attempting to travel into … Read more
The moment a person dies, their body begins to break down as cells wither and bacteria invade. But how long does it take for a body to fully decompose? Although the process of decomposition starts within minutes of death, there are a number of variables, including the ambient temperature, soil acidity and coffin materials, which … Read more
It’s the stuff of science fiction — parallel worlds that fan out in time and space. But do such parallel worlds exist? It turns out that at least some physics theories do allow for the existence of parallel universes — at least on the quantum level. In several interpretations of quantum mechanics, like the Many-Worlds … Read more
One of the most perplexing aspects of quantum mechanics is that tiny subatomic particles don’t seem to “choose” a state until an outside observer measures it. The act of measurement converts all the vague possibilities of what could happen into a definite, concrete outcome. While the mathematics of quantum mechanics provides rules for how that … Read more
Bigfoot, or Sasquatch, is one of North America’s most enduring legends. The scientific community largely dismisses the idea of a large, unknown ape-like creature sauntering through the forests because there’s never been any hard evidence that such an animal exists. Nonetheless, there have been thousands of reported eyewitness accounts over the last half century from … Read more
Falling in love may hit your heart, but what does it do to your brain? It turns out that falling in love corresponds with the release of key brain chemicals from certain regions of the brain, Dr. Gül Dölen (opens in new tab), an associate professor of neuroscience at the Johns Hopkins University School of … Read more
Ancient microbes whose existence predates the rise of nucleus-carrying cells on Earth may hold the secrets to how such complex cells first came to be. Now, for the first time, scientists have grown a large enough quantity of these microbes in the lab to study their internal structure in detail, Science reported. Researchers grew an … Read more
When a glassfrog falls asleep, it vanishes. Nestled atop a lush leaf, the frog’s bright green back blends right in, while its underbelly’s reddish hue quickly grows transparent. Now, a new study in the journal Science (opens in new tab) reveals that the northern glassfrog (Hyalinobatrachium fleischmanni) pulls off this feat by removing almost 90% … Read more
Researchers have proven that a metallic alloy of chromium, cobalt and nickel is officially the toughest material on Earth — more than 100 times tougher than the wonder material graphene. In a new study published Dec. 1 in the journal Science, researchers subjected the ultra-tough alloy to extremely cold temperatures, in order to test how … Read more
Once the stuff of science fiction, lab-grown meat could become reality in some restaurants in the United States as early as this year. Executives at cultivated meat companies are optimistic that meat grown in massive steel vats could be on the menu within months after one company won the go-ahead from a key regulator. In … Read more
