In both previous Ebola outbreaks in Africa and the current Ebola outbreak caused by the Bundibugyo virus in the Democratic Republic of the Congo, neighboring countries have been the most affected when it comes to cross-border spread. Van Zandvoort et al. note that decision-makers outside Africa may be considering border and travel policies to cut off international transmission routes. We identified and analyzed all known Ebola cases outside Africa and assessed the risk of undetected cases. ortho ebola virus It’s about considering the possibility of transmission outside Africa and weighing it against possible border and travel policies. The authors searched…
Researchers at Brazil’s Federal University of São Paulo (UNIFESP) have identified a molecule on the cell surface that could be a promising therapeutic target for cancer. This molecule plays an important role in tumor progression by regulating cell behavior. This FAPESP-supported study showed that overexpression of the Sindecam-4 (SDC4) receptor provides a protective shield to tumor cells. In laboratory experiments, the researchers silenced the receptor, halting the accelerated growth of tumor cells and causing them to resume responding to their naturally programmed cell death mechanisms. This study also received financial support from the National Council for Scientific and Technological Development…
People with genetic mutations associated with obesity are now more likely to be heavier than people with the same mutations born before the recent obesity epidemic. Liam Wright of University College London and colleagues report these findings in the June 19 issue of the Journal. PLOS genetics. Obesity rates among children and adults have risen sharply over the past 50 years. But strangely, rates of extreme obesity are increasing faster than the overall increase in body mass index (BMI), an estimate of body fat based on height and weight. This trend suggests that some people are particularly susceptible to environmental…
A spiral wave of neural activity appears and travels through the brain. Scientists want to know whether these traveling rotational waves play an overall role in sensing and interpreting internal and external stimuli, consolidating memory, and managing motor skills. We have discovered a new type of brain waves that specifically rotate across space and time, rely on circulatory anatomical circuits in the sensory cortex, and influence activity throughout the brain. ” Nick Steinmetz, Associate Professor of Neurobiology and Biophysics, University of Washington School of Medicine (Seattle) His team led the research. Details of these moving, whirling brain waves,…
The experiences we face early in life can leave a mark on our health in ways that reverberate for decades and even throughout our bodies. New research published today in the journal science (DOI:10.1126/science.aea4922) studied a unique group of free-living rhesus macaques who were tracked throughout their lives to record their experiences. Combining these medical histories with genomic data from 12 tissues collected during adulthood, this study provides some of the clearest molecular evidence to date that early life adversity leaves a system-wide lasting impression on the epigenome, the biological layer on the human genome that regulates gene activity. The…
Recent research suggests that inducing certain sleep-like brain wave patterns in awake mice may provide restorative effects to the brain that are normally only obtained by actually falling asleep. The findings show that the physical need for sleep and the memory-enhancing effects of adequate sleep can be replicated without animals losing consciousness. This study was recently published in the journal natural neuroscience. Sleep is a biological necessity for all mammals. It works to reset the brain and body after being awake for a long time. When animals are awake, they learn, move, and experience new things in their environment. This…
Despite the increase in the use of artificial intelligence, healthcare systems and organizations across the United States are lagging in its integration, according to a new study from Arcadia. Although 52% of respondents report that AI can fundamentally change healthcare with the right applications, nearly half (53%) of AI insights are only “partially integrated” into decision-making processes, and only 14% report that they are fully integrated at “key decision points.” This healthcare platform study garnered insights from 281 healthcare leaders across providers, payers, and service organizations at the HIMSS26 conference in March. “Healthcare leaders are increasingly united around the potential…
The Gila River is one of the Southwest’s most important waterways, providing water for communities, farms, and wildlife, and connecting the snow-covered mountains of southwestern New Mexico to the desert regions of southwestern Arizona. In years with high precipitation, winter snow accumulation in the Mogollon and Black Mountains provides much of the river’s spring runoff. This water helps replenish the San Carlos Reservoir created by Coolidge Dam. When full, this reservoir ranks as the largest lake in Arizona. The collapse of the snowpack drains the reservoir The situation in 2026 was dramatically different. Snowfall in the Gila River Basin has…
Recent research examines how emotions such as fear, anger, and hope shape Black women’s political behavior outside of the voting booth. Researchers found that the type of emotion and the topic that evoked it determined whether individuals engaged in low-effort tasks, such as signing petitions, or high-effort activities, such as protesting. The findings, published in The Journal of Race, Ethnicity, and Politics, show that black women are driven by a wide range of emotions that go far beyond superficial stereotypes. Political scientists frequently study how emotions predict voter behavior. Most of this research has historically focused on white Americans, and…
Now that summer has officially begun, millions of tourists are looking forward to their vacation, often heading to the coast to enjoy the beaches. However, this year A long shadow hangs over the tourism industry Bacterial growth in the sea has already forced the closure of several beaches in Spain. advertisement advertisement Indeed, in recent years various parts of Europe’s coastlines have faced pollution and health alerts, restricting access to the sea against the backdrop of rising water temperatures and increased tourism pressure. “The Mediterranean shows us what a hotter world is like,” he says.
