Ethereal color variant of mysterious plant is actually a new species
It was thought that there was only one species of the ghost-like Monotropastrum humile plant found in woodlands across East and Southeast Asia. In a major new discovery, botanists reveal that a rosy pink colored variant is actually a distinct new species, shaking up our understanding of this unusual-looking genus of plants. This 20-year study emphasizes the importance of combining various analytic

Eight Books to Comfort You When You're Lonely
The holidays are a notoriously fraught time for big feelings, loneliness chief among them. In 2017, the surgeon general declared loneliness an American " epidemic ," with "over 40% of adults " in the U.S. suffering from it. Globally, the rates rose even further when the coronavirus pandemic made gathering dangerous. What makes things tricky is that solitude is not the same as loneliness. Likewise
Homes that survived Boulder County fire hid another disaster inside: Research details this urban wildfire health risk
On Dec. 30, 2021, one of the most destructive wildfires on record in Colorado swept through neighborhoods just a few miles from our offices at the University of Colorado Boulder. The flames destroyed over 1,000 buildings, yet when we drove through the affected neighborhoods, some houses were still completely intact right next to homes where nothing was left to burn.

The mission is notable for another reason: the famous "Blue Marble" photograph of Earth fully illuminated by the sun. This stunning image supercharged the nascent environmental mo
Functional analyses of RNA-related enzymes using a next-generation DNA sequencer
Genetic information encoded in genomic DNA is transcribed to mRNAs and then the codons on mRNA are decoded by transfer RNAs (tRNAs) during protein synthesis. tRNAs deliver amino acids to ribosomes and proteins are synthesized from the amino acids on the ribosomes according to the decoded genetic information. Therefore, tRNA plays a key role during the translation of genetic information.

Is mining in space socially acceptable?
Traditional mining has been subject to a negative stigma for some time. People, especially in developed countries, have a relatively negative view of this necessary economic activity. Primarily that is due to its environmental impacts—greenhouse gas emissions and habitat destruction are some of the effects that give the industry its negative image.
Is the Milky Way normal?
Studying the large-scale structure of our galaxy isn't easy. We don't have a clear view of the Milky Way's shape and features like we do of other galaxies, largely because we live within it. But we do have some advantages. From within, we're able to carry out close-up surveys of the Milky Way's stellar population and its chemical compositions.

Study reveals inconsistent effect of ramet connection in homogeneous environments
Physiological or clonal integration is a key ecological benefit where stolon or rhizome connections between ramets allow for translocation of resources from source-sites to sink-sites (in patchy or heterogeneous environments) within the clone. However, negative effects of ramet connection have also been found in previous studies.

Model analysis of atmospheric observations reveals methane leakage in North China
Natural gas is a relatively clean burning fossil fuel, that causes less air pollution than coal and is widely used in the world. Recent studies have shown that the natural gas leaks from production, supply chain, and end-use facilities are a large source of atmospheric methane (CH4), and the leaking budget is underestimated in many places by bottom-up inventories.

Brown algae removes carbon dioxide from the air and stores it in slime
Brown algae take up large amounts of carbon dioxide from the air and release parts of the carbon contained therein back into the environment in mucous form. This mucus is hard to break down for other ocean inhabitants, thus the carbon is removed from the atmosphere for a long time, as researchers at the Max Planck Institute for Marine Microbiology in Bremen now show.

A new study that reconstructs the history of sea level at the Bering Strait shows that the Bering Land Bridge connecting Asia to North America did not emerge until around 35,700 years ago, less than 10,000 years before the height of the last ice age (known as the Last Glacial Maximum).

These creations demonstrate the possibilities of
New bacterial therapy approach to treat lung cancer
Researchers report that they have developed a new experimental pipeline to combine bacterial therapy with current cancer drugs. Their study, which explores resistance to bacterial therapy at the molecular level, has achieved better treatment efficacy without additional toxicity in laboratory models.
How the brain stores remote fear memory
A remote fear memory is a memory of traumatic events that occurred in the distant past — a few months to decades ago. A mouse study has now spelled out the fundamental mechanisms by which the brain consolidates remote fear memories. The study demonstrates that remote fear memories formed in the distant past are permanently stored in connections between memory neurons in the prefrontal cortex.
Some guts are better than others at harvesting energy
New research suggests that a portion of the Danish population has a composition of gut microbes that, on average, extracts more energy from food than do the microbes in the guts of their fellow Danes. The research is a step towards understanding why some people gain more weight than others, even when they eat the same.
Understanding the 'eating just one potato chip is impossible' gene
A research group has revealed that a transcription cofactor gene called CREB-Regulated Transcription Coactivator 1 (CRTC1) mediates the obesity-suppressing effects of melanocortin-4 receptor (MC4R) by regulating appetite for fats and oils, high-fat diet metabolism, and blood sugar. They found that there was no difference in weight gain between mice without CRTC1 in their MC4R-expressing neurons an
Massive 'marimo' algae balls at risk from deadly winter sunburn
Climate change could overexpose rare underwater 'marimo' algae balls to sunlight, killing them off according to a new study. Marimo are living fluffy balls of green algae. The world's largest marimo can be found in Lake Akan in Hokkaido, Japan's northern main island. Here they are sheltered from too much winter sunlight by a thick layer of ice and snow, but the ice is thinning due to global warmin

Looking for answers about how the brain works amid age-related hearing loss, researchers say they found that old mice were less capable than young mice of 'turning off' certain actively firing brain cells in the midst of ambient noise. The result, they say, creates a 'fuzzy' sound stage that makes it difficult for the brain to focus on one type of sound — such as spoken words — and filter out su

No One Can Decide If Grapefruit Is Dangerous

Johnson signed the Medicare bill in Independence, Missouri, alongside anothe
