A new study published in Nature Communications provides direct evidence that antidepressant use during pregnancy can impact a child’s brain development and contribute to the risk of mental health disorders later in life. The study, led by researchers at the University of Colorado Anschutz Medical Campus, focused on the effect of fluoxetine, commonly used in medications such as Prozac and Sarafem for treating depression and perinatal depression, on a developing prefrontal cortex. Since fluoxetine works by increasing the levels of serotonin in the brain, the researchers looked at the impact serotonin has on prefrontal ...

A revolutionary nanomaterial with huge potential to tackle multiple global challenges could be developed further without acute risk to human health, research suggests.  Carefully controlled inhalation of a specific type of graphene – the world’s thinnest, super strong and super flexible material – has no short-term adverse effects on lung or cardiovascular function, the study shows.  The first controlled exposure clinical trial in people was carried out using thin, ultra-pure ...

A dipole magnetic field, created by a ring current, is the most fundamental type of magnetic field that is found both in laboratories and in space. Planetary magnetospheres, such as Jupiter's, effectively confine plasma. The RT-1 project aims to learn from nature and create a magnetosphere-type high-performance plasma to realize advanced fusion energy. Simultaneously, the artificial magnetosphere offers a means to experimentally understand the mechanisms of natural phenomena in a simplified and controlled ...

Amid growing global concern over climate change and plastic pollution, researchers at Osaka Metropolitan University are making great strides in the sustainable production of fumaric acid – a component of biodegradable plastics such as polybutylene succinate, which is commonly used for food packaging. The researchers have managed to efficiently produce fumaric acid, which is traditionally derived from petroleum, using renewable resources, carbon dioxide, and biomass-derived compounds. In a previous study, a research team led by Professor Yutaka Amao of the Research Center for Artificial Photosynthesis at ...

A 280-million-year-old fossil that has baffled researchers for decades has been shown to be, in part, a forgery following new examination of the remnants. The discovery has led the team led by Dr Valentina Rossi of University College Cork, Ireland (UCC) to urge caution in how the fossil is used in future research. Tridentinosaurus antiquus was discovered in the Italian alps in 1931 and was thought to be an important specimen for understanding early reptile evolution. Its body outline, appearing dark against the surrounding rock, was initially interpreted ...

Trace metals are nutrient elements, like zinc, that animals and plants need in small amounts to function properly. Animals generally get trace metals in their diets or through environmental exposures, while plants take their trace minerals up from soil. If we get too little, we may experience a deficiency, but the opposite can also be true: too much of a trace metal can be toxic. Scientists believe that up to 50% of the trace metals in soils and urban environments may be bound to the surfaces of mineral grains — rendering the trace metals ...

People with disabilities are often at higher risk for exposure to HIV due to barriers in engaging healthcare and other systemic factors and are thus considered a priority for prevention and testing efforts. However, these efforts don’t always extend to people with intellectual disabilities due to the perception that people with intellectual disabilities are mostly asexual. Researchers at University of Michigan Health conducted one of the largest epidemiological studies of individuals with intellectual and developmental disabilities to closely examine where the gaps in HIV care lie and found large disparities in care for Black patients as well as for patients ...

A new measure that compares earthquake-related fatalities to a country’s population size concludes that Ecuador, Lebanon, Haiti, Turkmenistan, Iran and Portugal have experienced the greatest impact from fatalities in the past five centuries. The new impact measure, introduced in the Bulletin of the Seismological Society of America by Max Wyss and colleagues at International Centre for Earth Simulation Foundation, is called the earthquake fatality load or EQFL. The EQFL of a particular earthquake is the ratio of earthquake fatalities to the population estimate for the country in the year of the earthquake. In their study, Wyss, Michel Speiser ...

New findings from researchers at the University of British Columbia suggest that cannabis could play a role in addressing the ongoing opioid overdose crisis. A new publication from Dr. Hudson Reddon, alongside UBC Okanagan’s Dr. Zach Walsh and UBC Vancouver’s Dr. M-J Milloy, observed that using cannabis is associated with decreased use of crystal methamphetamine among people at highest risk of overdose in Vancouver’s Downtown Eastside. About 45 per cent of the study’s participants reported using cannabis to manage their cravings for stimulant drugs ...

EAST LANSING, Mich. – In creating five new isotopes, an international research team working at the Facility for Rare Isotope Beams, or FRIB, at Michigan State University has brought the stars closer to Earth. The isotopes — known as thulium-182, thulium-183, ytterbium-186, ytterbium-187 and lutetium-190 — were reported Feb. 15 in the journal Physical Review Letters. These represent the first batch of new isotopes made at FRIB, a user facility for the U.S. Department of Energy ...

Oxygen is fundamental to sustaining life on Earth. The ocean gets its oxygen from its uppermost layers in contact with the atmosphere. As our planet continues to warm, the ocean is gradually losing its capacity to absorb oxygen, with severe consequences on marine ecosystems and human activities that depend on them. While these trends will likely continue in the future, it remains unclear how ocean oxygen will redistribute across the ocean interior, where ocean currents and biological degradation of biomass dominate over atmospheric diffusion. “Marine sediments are the history book of the ocean. ...

Springtime brings native wildflowers to bloom in the Santa Monica Mountains, northwest of Los Angeles. These beauties provide food for insects, maintain healthy soil and filter water seeping into the ground — in addition to offering breathtaking displays of color.  They’re also good at surviving after wildfire, having adapted to it through millennia. But new research shows wildflowers that usually would burst back after a blaze and a good rain are losing out to the long-standing, double threat of city smog and nonnative weeds. A recent study led by Justin Valliere, assistant professor in the UC ...

In the late 1800s and early 1900s, anti-Chinese sentiment in the United States was high, as working-class laborers in the country viewed Chinese workers as a threat. Prior research has found that during that period, approximately 400,000 Chinese migrants came to the U.S., many of whom went to California to build the Transcontinental Railroad. Following the project's completion, competition for jobs grew tougher, and passage of the Chinese Exclusion Act in 1882 banned Chinese laborers from immigrating to the U.S. But ...

A new study published in Atmospheric Environment by researchers at the University of North Carolina at Chapel Hill analyzed space and time trends for fine particulate matter (PM2.5) in the continental United States to track the progress of regulatory actions by federal, state and local authorities aimed at curbing air pollution. The team found that while the annual average concentration for PM2.5 had been significantly reduced, its chemical composition had changed during the study period of 2006 to 2020. Their analysis suggests targeted strategies to reduce specific pollutants for different regions ...

MIAMI, FL – February 15, 2024 – A study co-led by researchers at Miami Cancer Institute, part of Baptist Health South Florida, found that ablative stereotactic magnetic resonance (MR)-guided adaptive radiation therapy may improve local control (LC) and overall survival (OS) in patients with borderline resectable (BRPC) and locally advanced pancreas cancer (LAPC). Long-term outcomes from the Phase 2 SMART trial demonstrate encouraging OS and limited toxicity as published recently in Radiotherapy & Oncology (“The Green Journal”). “Pancreatic ductal adenocarcinoma is a leading cause of cancer death. Surgery is the only known ...

One of the grand challenges for materials science is the design and discovery of new materials that address global priorities such as Net Zero. In a paper published in the journal Science, researchers at the University of Liverpool have discovered a solid material that rapidly conducts lithium ions. Such lithium electrolytes are essential components in the rechargeable batteries that power electric vehicles and many electronic devices. Consisting of non-toxic earth-abundant elements, the new material has high ...

Why do Serengeti zebra, wildebeest, and gazelle – all sharing limited food resources – follow the same migratory routes, one after another, in a body-size dependent way? This longstanding question has now been evaluated by researchers who used novel data to show how a balance of species interactions and ecological factors regulate this process. They say competition pushes zebra ahead of the wildebeest, and wildebeest then eat plants in a way that facilitates development of newer growth the trailing gazelle like. “Our results highlight a balance between facilitative and competitive forces,” the authors say. Large seasonal migrations are a ...

Oxygenation in the tropical North Pacific Ocean increased during a warm climatic interval that occurred roughly 56 million years ago, despite high global temperatures, according to a new study. Its findings offer insights into how modern tropical oceans may respond to ongoing anthropogenic climate warming. The availability and distribution of dissolved oxygen in Earth’s oceans play a fundamental role in supporting marine ecosystems and marine life. However, oxygen in the global oceans is declining in response to anthropogenic warming. Although these trends writ large are predicted to continue, the future of oxygen in the highly productive ...

Cresomycin – a novel synthetic molecule – demonstrates remarkably robust efficacy against multiple, evolutionary divergent forms of antimicrobial resistance (AMR), researchers report. The emergence and widespread distribution of bacteria broadly resistant to approved antibiotics raises serious global public health concerns. Given the growing rate of deaths attributable to antimicrobial resistance (AMR) worldwide, it’s evident the pace of discovery and development of antibiotics effective against AMR has not kept up with the need. Many small ...

Scientists have observed so-called 'roaming' chemical reactions, those that at certain points move away from the lowest minimum energy 'path of least resistance', in highly excited energy states for the first time.   Chemical reactions are supposed to occur along their minimum energy paths. In recent years, so-called roaming reactions that stray far from this path have begun to be observed, but only for chemical species in their ground state or, at most, their first excited state. However, researchers have now observed a roaming reaction even in highly excited energy states. The researchers ...
