Jewel beetles evolve to see new colors by duplicating their genes
Jewel beetles are striking insects, easily recognized by their vivid colors and metallic sheen. Possessing large, well-developed eyes, jewel beetles use vision and color for a range of different behaviors, including finding mates and host plants......»»
Beats x Kim collab reaches the new Beats Pill speaker
Kim Kardashian has teamed up with Beats for a third collaboration that brings two new colors of the new Beats Pill speaker......»»
Scientists discover "selfish DNA" crucial for early human development
A critical transition in early human development is regulated not by our own genes, but by DNA elements called transposons that can move around the genome, Sinai Health researchers have found......»»
What colors do bees see? And how do we know?
I was reading a children's book about insects to my daughter, and it said that bees see colors differently than humans do. My daughter immediately asked, in short succession: "What colors do they see? Why? How do we know?" I did some homework to find.....»»
How did magma oceans evolve on early Earth and Mars? Iron chemistry and primordial atmospheres offer clues
Before Earth became the blue planet, it was engulfed by a very different kind of ocean: a vast, deep magma ocean reaching down hundreds or perhaps even thousands of kilometers......»»
Animal social interactions could speed up evolution
Scientists typically predict how species evolve by looking at their genes and the environment they live in, but new research from the University of Aberdeen has highlighted a key factor that's often overlooked: social interactions, where the genes of.....»»
Fall is here: Why do some trees lose their leaves while others stay green?
The autumn has arrived and northeastern North America's forests will soon grace us with a breathtaking palette of reds, yellows and golds. These vivid colors will then fade, giving way to bare branches, as the fallen leaves blanket the forest floor,.....»»
Researchers discover how plants produce a novel anti-stress molecule
New research identifies for the first time the genes that help plants grow under stressful conditions—with implications for producing more sustainable food crops in the face of global climate change......»»
Mexican jumping beans jump to safety in a dynamic world—light could influence how moth larvae avoid extreme heat
What makes Mexican jumping beans jump? New research from Binghamton University reveals that Mexican jumping bean larvae respond to different colors of light, jumping more vigorously under different hues, which can help them avoid potentially dangerou.....»»
Nobel Prize in medicine awarded for discovery of microRNAs, the molecules that control our genes
Two scientists, Victor Ambros (UMASS Chan Medical School in the US) and Gary Ruvkun (Harvard Medical School in the US), have won the 2024 Nobel prize in medicine or physiology......»»
Medicine Nobel goes to previously unknown way of controlling genes
MicroRNAs control the activity of many key genes but were unknown before 1993. On Monday, the Nobel Committee announced that two US researchers, Victor Ambros and Gary Ruvkun, wil.....»»
Study identifies compounds that extend longevity of Japanese morning glory flowers
The longevity of plant flowers is controlled by genetically programmed mechanisms. After a certain amount of time after flowering, the expression of genes associated with programmed cell death is induced and cellular components such as proteins and n.....»»
First-ever artificial cell nuclei created in living egg from purified DNA injection
A research group is the first in the world to succeed in constructing artificial cell nuclei by injecting purified DNA solution instead of sperm into living mouse eggs. Their findings are published in the journal Genes to Cells......»»
Color, color everywhere—mother nature shares a mosaic of bright colors this fall in New England
Cool, crisp weather can trigger the urge to get out and go leaf peeping and this year could be a particularly good year to hit the road and admire New England's spectacular foliage season. According to Steve Roberge, Extension forestry specialist and.....»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»
Bioinspired yarn can harvest water from fog
Scientists have developed a bioinspired yarn capable of harvesting water from fog, providing an innovative solution to water scarcity in arid regions. By imitating the alternating hydrophobic and hydrophilic patterns seen in desert beetles and the wa.....»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
The biological marvels of the seabed are being mined to create commercial products—here are the risks
Thousands of genes from deep-sea marine life are being used to create new commercial products ranging from pharmaceuticals to cosmetics. Genes are segments of DNA that provide instructions for making other molecules that are essential for the structu.....»»
Hummingbirds thrive on an extreme lifestyle. Here’s how.
Nightly suspended animation, sugary diet, backwards flight, and long migrations help. Enlarge / Hummingbirds—like this golden-tailed sapphire from South America—draw the eye with their bright colors and busy, hovering flight......»»
Bacterial "flipping" allows genes to assume different forms
Imagine being one cartwheel away from changing your appearance. One flip, and your brunette locks are platinum blond. That's not too far from what happens in some prokaryotes, or single-cell organisms, such as bacteria, that undergo something called.....»»
Naked mole-rat found to have lost infection-resistant proteins
Scientists have found that the naked mole-rat—an underground rodent that lives up to 40 years—has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious.....»»
