Researchers have discovered a mechanism in a small area of the brain that regulates whole-body glucose balance without affecting body weight.

Large thunderstorms in the Southern Great Plains of the U.S. are some of the strongest on Earth. In recent years, these storms have increased in frequency and intensity, and new research shows that these shifts are linked to climate variability.
Diet rich in sugar and fat leads to disruption in the gut's microbial culture and contributes to inflammatory skin diseases such as psoriasis. Research shows that switching to a more balanced diet restores the gut's health and suppresses inflammation.
The story of efforts to conserve the endangered oribi in South Africa represent a diaspora of issues as varied as the people who live there.
In two new studies on life in the seafloor of the Guaymas Basin, in the Gulf of California, scientists show that distinct regions within the Basin harbor specially adapted microorganisms; discover new microbial inhabitants of this deep-sea community; and suggest how the community may be dramatically influencing carbon cycling in the hot seafloor sediments.
Years before they are diagnosed, persons with multiple sclerosis (MS) make significantly more visits to doctors and hospitals than others. Specialists have recently discussed whether this might represent a preliminary phase of MS - known as a prodrome. A new study suggests that, in many cases, the complaints may relate to unrecognized early clinical MS events.
A new study offers quantitative evidence linking psychological stress to graying hair in people.
The nucleus is much more than a storage compartment for chromosomes: It also contains the complex machinery producing transcripts of the genes that are currently needed and releases them into the cell body. Some of the proteins involved herein are not evenly distributed in the nucleus, but cluster at specific sites. A study now shows how these 'flash mobs' are regulated.
A research team recently published the results of a three-year study of cognitive changes in older adults who complained that their cognitive ability was worsening though clinical assessments showed no impairments. The MRI studies showed significant changes in functional connectivity in two areas of the brain.
Pancreatic cancer cells typically rely on a mutant version of the KRAS protein to proliferate. These cancer cells can also survive losing KRAS by activating alternative growth pathways. Scientists discovered a new interaction between mutant KRAS and a protein complex called RSK1/NF1 that may be the source of this adaptive resistance.
The mystery of an exotic kind of superconductivity has been solved, researchers say -- by showing that it just does not exist. An effect, which has been celebrated since the 1990s has now been shown to be standard superconductivity. Still, this realization leads to important new ideas.
Few animals can regenerate their spinal cord after an injury. The axolotl can mobilize stem cells in its spinal cord to regrow the lost tissue. An international team of scientists have investigated the early stages of this process.
Researchers have identified a combination of biological markers in patients with dengue that could predict whether they go on to develop moderate to severe disease.
Researchers developed a novel system to analyze ancient plant DNA in the sediment of Tikal's temple and palace reservoirs to identify more than 30 species of trees, grasses, vines and flowering plants that lived along its banks more than 1,000 years ago. Their findings paint a picture of a lush, wild oasis in the ancient Maya city.
The link between the different hierarchies of personality, sleep patterns and even genetics has now been discovered.
Coastal wetlands like seagrass meadows, mangroves, and salt marshes play vital roles along the shoreline, from providing a buffer against storm surges, to providing critical habitat for animals, to capturing atmospheric carbon. We are still just beginning to comprehend the intricate workings of these highly productive ecosystems and their role in mitigating the climate crisis, but researchers are...
A novel way of synthesizing an essential powder is key to raising the efficiency of perovskite solar cells, say researchers.
Researchers have recently identified and described a new genus and species of xanthid crab found in Okinawa Island, Ryukyu Islands, Japan. Named Mabui calculus, it is the first among the 7,800 species of known crabs to have strongly asymmetrical male and female reproductive structures.
A new study shows inherited risk of early-onset cancer is significantly higher among Latino and African American families for solid tumors, and Asian/Pacific Islander families for blood-based cancers, compared to non-Latino white families in California. Researchers used California population-based health registries to evaluate the relative cancer risk among first-degree relatives of patients...
Oregon State University research has identified the oldest known specimen of a fungus parasitizing an ant, and the fossil also represents a new fungal genus and species.
Scientists have uncovered a mechanism that allows a protein complex to bind to DNA without impeding some of the important processes of cell division. Their findings could further understandings of developmental disorders arising from mutations in the gene that codes for the complex.
To understand what role an individual gene plays, biologists have, for 100 years, been using a trick of nature: While in principle, the genome in all cells of an organism is the same, mutations arise in individual cells. These mutations differentiate a cell from its neighbors, forming a 'genetic mosaic.' Now, researchers have advanced genetic mosaic analysis, making almost all genes in the mouse...
Biologists have used rice to successfully illuminate the mechanism by which plants regulate the amount of starch produced via photosynthesis. This knowledge could contribute towards improving the quality and yield of agricultural crops.
Without an audience, men run slower and women faster: The lack of spectators during the coronavirus pandemic appears to have had a noticeable effect on the performance of athletes at the 2020 Biathlon World Cup, a new study shows. According to the new analysis, women also performed better in complex tasks, such as shooting, when an audience was present while men did not.
The venom of a caterpillar, native to South East Queensland, shows promise for use in medicines and pest control, researchers say.
