People with autism often suffer from gut problems, but nobody has known why. Researchers have now discovered the same gene mutations - found both in the brain and the gut - could be the cause.
The discovery confirms a gut-brain nervous system link in autism, opening a new direction in the search for potential treatments that could ease behavioural issues associated with autism by targeting the gut.
A Florida State University researcher has found gender inequality in U.S. states is bad for everybody's health.
In a new study published in the American Sociological Review, FSU Assistant Professor Patricia Homan developed a new structural sexism approach to the study of gender inequality and health. Her approach goes beyond sexist mistreatment by individuals to examine how the degree of systematic gender inequality in power and resources -- i.e. structural sexism -- in a society can impact people's health.
BIRMINGHAM, Ala. - While studying one of the smallest DNA viruses known, Sunnie Thompson, Ph.D., may have found a new way to help prevent kidney damage following organ transplant.
The University of Alabama at Birmingham researcher studies BK polyomavirus, a major source of kidney damage and rejection in transplant recipients. Nearly all humans silently harbor polyomaviruses in their bodies; but when transplant recipients receive drugs to suppress their immune system to prevent graft rejection, the virus can reactivate, resulting in damage to the kidney.
Successful new field tests of a continuous-variable quantum key distribution (CV-QKD) system over commercial fiber networks could pave the way to its use in metropolitan areas.
That is the key achievement from a joint team of Chinese scientists, published today in Quantum Science and Technology, which demonstrates CV-QKD transmission over commercial deployed fiber link with a distance of 50 kilometres.
A study conducted by scientists from Brazil, the United States and Portugal investigated the accuracy and consistency of different satellite data collections with regard to the location and size of burned areas in the Cerrado biome, the Brazilian savanna.
Scientists at Texas A&M University are harnessing the combined power of organic nanomaterials-based chemistry and a natural product found in crustacean exoskeletons to help bring emergency medicine one step closer to a viable solution for mitigating blood loss, from the hospital to the battlefield.
EAST BOOTHBAY, Maine - New research connects recent changes in the movement of North Atlantic right whales to decreased food availability and rising temperatures in Gulf of Maine’s deep waters. Right whales have been showing up in unexpected places in recent years, putting the endangered species at increased risk. The study, which was published in Oceanography and conducted by scientists from more than 10 institutions, provides insights to this key issue complicating conservation efforts.
BUFFALO, N.Y. -- A new University at Buffalo study based on levels before, during and after the Beijing Olympics reveals how air pollution affects the human body at the level of metabolites.
Researchers found that 69 metabolites changed significantly when air pollution changed. Their results were published today (May 29) in the journal Environmental Health Perspectives.
Scientists of Far Eastern Branch of the Russian Academy of Sciences (FEB RAS), Far Eastern Federal University (FEFU) and National Taiwan University comprehended state of the art scientific knowledge about plants stress response activated by unfavorable environmental factors. Researchers proposed ways to improve crop plants stress resistance by developing one's heritable stress response memory which will allow preserving the stability of the yield obtained worldwide. A related review published in Trends in Plant Science.
For all the evidence that the benefits of reducing greenhouse gases outweigh the costs of regulation, disturbingly few domestic climate change policies have been enacted around the world so far.
So say UC Santa Barbara professor and economist Kyle Meng, and co-author Ashwin Rode, a former UCSB Ph.D. student now at the University of Chicago, in a paper published in the journal Nature Climate Change.
CHAMPAIGN, Ill. -- After exposing more than 70 million grain amaranth seeds to a soil-based herbicide, researchers were not able to find a single herbicide-resistant mutant. Though preliminary, the findings suggest that the mutation rate in amaranth is very low, and that low-level herbicide application contributes little - if anything - to the onset of new mutations conferring resistance, researchers say.
The study is reported in the journal Weed Science.
A new compound developed by University of Sheffield experts has killed antibiotic resistant gram-negative bacteria, including E. coli, during tests
New treatments for gram-negative bacteria are vital as they are rapidly becoming immune to current drugs
Antimicrobial resistance is already responsible for 25,000 deaths in the EU each year
The research could pave the way for new treatment of life-threatening superbugs
Embedded at the end of chromosomes are structures called "telomeres" that in normal cells become shorter as cells divide. As the shortening progresses it triggers cell proliferation arrest or death. Cancer cells adopt different strategies to overcome this control mechanism that keeps track of the number of times that a cell has divided. One of these strategies is the alternative lengthening of telomeres (ALT) pathway, which guarantees unlimited proliferation capability. Now, a research group led by Claus M.
The ROSETTA-Ice project, a three-year, multi-institutional data collection survey of Antarctic ice, has assembled an unprecedented view of the Ross Ice Shelf, its structure and how it has been changing over time. In a study published today in Nature Geoscience, the ROSETTA-Ice team members detail how they discovered an ancient geologic structure that restricts where ocean water flows. The discovery suggests that local ocean currents may play a critical role in the ice shelf's future retreat.
Winters in the northern hemisphere are brutal. The harsh conditions drive some species to hibernate; bears reduce their metabolic state to conserve energy until spring. Forests also endure winter by conserving energy; they shut down photosynthesis, the process by which a green pigment called chlorophyll captures sunlight and carbon dioxide (CO2) to produce the chemical energy that fuels the plants. The total production of chemical energy resulting from photosynthesis is called Gross Primary Production (GPP).
