Diabetes seldom occurs in newborns--a condition known as neonatal diabetes. But when it does, it's mostly due to a mutation in a single gene such as the KCNJ11 or insulin (INS). This early-onset type of diabetes differs from type-1 diabetes in that it occurs within the first six months of life and can be either transient or permanent. Most of the mutations that underly this disease prevent the pancreas from producing sufficient insulin, which leads to high blood glucose levels or hyperglycemia.
A new way to treat acid mine drainage (AMD) could help transform the environmental pollution problem into an important domestic source of the critical rare earth elements needed to produce technology ranging from smart phones to fighter jets, according to Penn State scientists.
The COVID-19 pandemic exposes weaknesses in the supply chain when countries go into lockdown. Some are small, such as the toilet paper shortages early on, that, while annoying, were eventually resolved. But what happens when the effects of the pandemic reach the food systems of countries highly reliant on food imports and income from abroad, and commerce slows to a halt?
Using stem cells to restore lost functions due to spinal cord injury (SCI) has long been an ambition of scientists and doctors. Nearly 18,000 people in the United States suffer SCIs each year, with another 294,000 persons living with an SCI, usually involving some degree of permanent paralysis or diminished physical function, such as bladder control or difficulty breathing.
Climate change and disruption of the ecosystem have the potential to profoundly impact the human body. Xue Ming, professor of neurology at Rutgers New Jersey Medical School, who recently published a paper in the International Journal of Environmental Research and Public Health on the effects of climate change on allergies, autoimmunity and the microbiome -- the beneficial microorganisms that live on and inside the human body -- discusses how the delicate balance of the environment affects conditions such as allergies, autism and immune disorders.
One million years ago, the extinction of large-bodied plant-eaters changed the trajectory of life on Earth. The disappearance of these large herbivores reshaped plant life, altered fire regimes across Earth's landscapes, and modified biogeochemical cycling in such a way that Earth's climate became slightly colder.
Catalysts speed up chemical reactions and form the backbone of many industrial processes. For example, they are essential in transforming heavy oil into gasoline or jet fuel. Today, catalysts are involved in over 80 percent of all manufactured products.
The amount of micro plastic pollution in waters around the Maldives, a global tourist destination known for its beautiful coastline, is amongst the highest in the world and has the potential to severely impact marine life in shallow reefs and threaten the livelihoods of island communities.
Microplastics are pieces of plastic waste that measure less than 5 millimetres long, and due to their often microscopic size are considered invisible water pollutants. Small pieces of plastic can break down over time from plastic bottles, textiles and clothing, remain in the world's oceans.
In a paper published in NANO, a team of researchers from Chengdu Development Center of Science and Technology have significantly enhanced the performance of titanium niobium oxides for lithium-ion batteries. This has applications in electric vehicles and mobile electronics.
Flying insects and parasites are often vectors for disease, but a mosquito needs to first find someone before they can bite them. In a recent study published in Frontiers in Ecology and Evolution, researchers examined bird nests in order to understand how insects and parasites detect gases such as carbon dioxide and methane as a way to locate their hosts.
As a global center for petrochemical manufacturing, Houston, Texas, experiences some of the worst air quality in the country, according to the U.S. Environmental Protection Agency. Evidence suggests that air pollution disproportionately affects low-income, non-white and Hispanic residents, but it's difficult to directly observe differences in pollutants between neighborhoods. Now, researchers reporting in Environmental Science & Technology have used airplanes and a satellite to uncover disparities in nitrogen dioxide amounts in the atmosphere above Houston.
PITTSBURGH, Aug. 5, 2020 - Researchers at UPMC Children's Hospital of Pittsburgh and Promundo-US found that men who harbor more harmful attitudes about masculinity -- including beliefs about aggression and homophobia -- also tend toward bullying, sexual harassment, depression and suicidal thoughts.
Researchers have examined what's currently known about the neuroendocrine effects of grief and whether biological factors can predict complicated or prolonged grief after the death of a loved one. The findings appear in the Journal of Neuroendocrinology.
A new analysis published in IBIS examines whether bacteria, viruses, and other microorganisms that are present in wild vultures cause disease in the birds, and whether vultures play a role in spreading or preventing infectious diseases to humans and other animal species.
A survey conducted immediately before and after the 2016 US presidential election reveals that the election of Donald Trump had a negative effect on Europeans' image of the United States, but it did not seem to affect the willingness of Europeans to sign a trade and investment agreement with the country.
