Many of the microbes that live in your gut are also found in your stool, and fecal microbiota transplants (FMTs) are being studied to determine whether they can improve health outcomes in patients with various diseases such as ulcerative colitis and Crohn's disease. However, it is important to recognize that FMT does carry some risk such as bloodstream infections and the transmission of drug-resistant bacteria.
A common variation in a human gene that affects the brain's reward processing circuit increases vulnerability to the rewarding effects of the main psychoactive ingredient of cannabis in adolescent females, but not males, according to preclinical research by Weill Cornell Medicine investigators. As adolescence represents a highly sensitive period of brain development with the highest risk for initiating cannabis use, these findings in mice have important implications for understanding the influence of genetics on cannabis dependence in humans.
There are numerous articles on how friendships change in your 20s, 30s, and after marriage or parenthood. What we don't know is how ubiquitous these changes are throughout the animal kingdom. Researchers from Archbold Biological Station describe the social lives of Florida Scrub-Jays in different stages of life in the journal PeerJ on February 10, 2020.
Citizen scientists have uncovered a bizarre pairing of two brown dwarfs, objects much smaller than the Sun that lack enough mass for nuclear fusion. The discovery, reported in The Astrophysical Journal and confirmed by a scientific team led by astrophysicist Jackie Faherty at the American Museum of Natural History, shows that brown dwarf systems--the formation of which are still poorly understood--can be very low mass and extremely far apart yet inexorably linked.
Secular cultures which are tolerant of minority groups and respectful of individuals' rights tend to have more wealth, education and democracy, a new study by University of Bristol scientists has found.
New research, which surveyed nearly half a million people across 109 countries, shows that changes in culture generally comes before any improvements in wealth, education and?democracy, rather than the other way around.
What The Studies Did: These two related studies and editorial examined the association of sexual orientation and gender identity with a history of self-reported skin cancer.

Authors: Arash Mostaghimi, M.D., M.P.A., M.P.H., of Brigham and Women's Hospital and Harvard Medical School in Boston, is the corresponding author of both studies.
Hookworms infect nearly around 700 million people in the world, mostly in countries where sanitation is poor, and people often walk barefoot.
The body's immune system is critical to attacking the hookworm, but these parasites are masters of escape and individuals typically remain infected throughout their lifetime, often resulting in death or complications stemming from anaemia.
Monash University researchers have uncovered a key way that hookworms evade the immune system - providing new hope in the search for a vaccine.
Boston, MA -- In the largest study of skin cancer rates among gay, lesbian or bisexual individuals, investigators from Brigham and Women's Hospital report important differences in skin cancer prevalence among sexual minorities. Rates of skin cancer were higher among gay and bisexual men compared to heterosexual men but lower among bisexual women than heterosexual women.
Scientists have discovered hundreds of unusually large, bacteria-killing viruses with capabilities normally associated with living organisms, blurring the line between living microbes and viral machines.
These phages -- short for bacteriophages, so-called because they "eat" bacteria -- are of a size and complexity considered typical of life, carry numerous genes normally found in bacteria and use these genes against their bacterial hosts.
HOUSTON -- Loss of an important tumor-suppressing gene allows head and neck cancer to spin off signals to nearby nerves, changing their function and recruiting them to the tumor, where they fuel growth and cancer progression, researchers from The University of Texas MD Anderson Cancer Center report in the journal Nature today.
A large proportion of highly active men watch more television than their low-active peers do. In contrast, highly active women watch less television than low-active women do.
revious studies have found prolonged television time to be more harmful to health than other domains of sedentariness. A recent longitudinal study with a ten-year follow-up examined how the television viewing time of Finnish adults was associated with their physical activity level during leisure-time.
Researchers at North Carolina State University have developed a new technique for shielding electronics in military and space exploration technology from ionizing radiation. The new approach is more cost effective than existing techniques, and the secret ingredient is...rust.
By creating neatly spaced slits in a clay mineral, University of Groningen Professor of Experimental Solid State Physics Petra Rudolf was able to filter water to remove a toxic herbicide. After removing the pollutant by heating the material, the clay can be reused. Together with colleagues from Greece, Rudolf presents this proof of principle study in the journal Environmental Science Nano.
Radiation from cell phones is associated with higher rates of thyroid cancer among people with genetic variations in specific genes, a new study led by the Yale School of Public Health finds.
RESEARCH TRIANGLE PARK, N.C. -- Researchers working on an Army project developed nanoscale thermal switches that are key to thermal management of nanoscale devices, refrigeration, data storage, thermal computing and heat management of buildings.
The journal Nature Nanotechnology published an Army-funded study from University of Michigan researchers that showed for the first time how a nanoscale thermal switch can be built by employing nanoscale effects that arise when heat is transferred between a hot and cold nanoscale-thick membrane via thermal radiation.
