A new genetic analysis suggests some mosquitos’ taste for human blood may date back 1.8 million years
From the 1950s to 1970s, discovery of enzymes began by identifying new chemical reactions within cell-free extracts, but their molecular identification among (function unknown) hypothetical genes (proteins) is difficult. Sugar acids are compounds formed by the oxidation of
Scientists at the University of Oxford have finally settled a decades-long mystery about the Moon’s magnetic field — and it turns out both sides were right. By reanalyzing Apollo mission rocks, they discovered that the Moon did occasionally generate an incredibly powerful
The preference of some mosquitoes in the Anopheles leucosphyrus (Leucosphyrus) group—including those that transmit malaria—for feeding on humans may have evolved in response to the arrival of early hominins in Southeast Asia around 1.8 million years ago. The findings are
When you make a small mistake that doesn't harm anyone else—such as tripping over a curb or misremembering a name—people will like you more if you can laugh at yourself rather than act embarrassed, finds research published by the American Psychological Association.
A DNA analysis suggests mosquitoes shifted from nonhuman primates to early humans nearly 2 million years ago.
About 2 million years ago, they evolved to feed on Homo erectus The post Mosquitoes Developed a Taste for Human Blood Before We Existed appeared first on Nautilus .
Seven firms reported inconsistent results on the same sample, some over multiple tests. These gut microbe discrepancies could have health consequences.
The science and the regulations to underpin these test “just aren’t there yet,” researchers say
When you look up at the night sky, it appears unchanging. But if you look deep enough you will find that the sky is in fact constantly shifting. Satellites, asteroids and interstellar objects pass by. Stars not only shine brightly, they can suddenly burst with energy or explode
When we look up at the night sky and see a satellite glide past, we might not consider climate change or the ozone layer. Space may feel separate from the environmental systems that sustain life on Earth. But increasingly, the way we build, launch and dispose of satellites is
In many quantum materials—materials with unusual electrical and magnetic properties driven by quantum mechanical effects—electrons can organize themselves into Landau levels. Landau levels are essentially quantized energy states that form when charged particles move in a
