Food for thought: New maps reveal how brains are kept nourished
2021-03-02
Our brains are non-stop consumers. A labyrinth of blood vessels, stacked end-to-end comparable in length to the distance from San Diego to Berkeley, ensures a continuous flow of oxygen and sugar to keep our brains functioning at peak levels.
But how does this intricate system ensure that more active parts of the brain receive enough nourishment versus less demanding areas? That's a century-old problem in neuroscience that scientists at the University of California San Diego have helped answer in a newly published study.
Studying the brains of mice, a team of researchers led by Xiang Ji, David Kleinfeld and their colleagues has deciphered the question of brain energy consumption and blood vessel density through newly developed maps that detail ...
Smaller, faster, greener
2021-03-02
When you think about your carbon footprint, what comes to mind? Driving and flying, probably. Perhaps home energy consumption or those daily Amazon deliveries. But what about watching Netflix or having Zoom meetings? Ever thought about the carbon footprint of the silicon chips inside your phone, smartwatch or the countless other devices inside your home?
Every aspect of modern computing, from the smallest chip to the largest data center comes with a carbon price tag. For the better part of a century, the tech industry and the field of computation ...
Cooperative eco-driving automation improves energy efficiency and safety
2021-03-02
Imagine you're driving up a hill toward a traffic light. The light is still green so you're tempted to accelerate to make it through the intersection before the light changes. Then, a device in your car receives a signal from the controller mounted on the intersection alerting you that the light will change in two seconds -- clearly not enough time to beat the light. You take your foot off the gas pedal and decelerate, saving on fuel. You feel safer, too, knowing you didn't run a red light and potentially cause a collision in the intersection.
Connected and automated vehicles, which can interact vehicle to vehicle (V2V) and between vehicles and roadway ...
Aggressive intervention recommended to prevent pediatric diabetes
2021-03-02
Type 2 diabetes, once considered an adult disease, is increasingly causing health complications among American youth. A research review published in the Journal of Osteopathic Medicine suggests physicians should work to more aggressively prevent pediatric diabetes.
Because few pediatric Type 2 diabetes treatment options are available, prevention is unusually important. To improve health outcomes, the paper's authors recommend physicians conduct regular screenings of children and adolescents, adopt a high level of suspicion, and intervene early and often with families who have children at risk for prediabetes and T2 diabetes.
"Pediatric type 2 diabetes is more progressive and aggressive than adult-onset Type 2 diabetes," ...

Indoors, outdoors, 6 feet apart? Transmission risk of airborne viruses can be quantified
2021-03-02
In the 1995 movie "Outbreak," Dustin Hoffman's character realizes, with appropriately dramatic horror, that an infectious virus is "airborne" because it's found to be spreading through hospital vents.
The issue of whether our real-life pandemic virus, SARS-CoV-2, is "airborne" is predictably more complex. The current body of evidence suggests that COVID-19 primarily spreads through respiratory droplets - the small, liquid particles you sneeze or cough, that travel some distance, and fall to the floor. But consensus is mounting that, under the right circumstances, smaller floating particles called aerosols can carry the virus over longer distances and remain ...
Novel drug prevents amyloid plaques, a hallmark of Alzheimer's disease
2021-03-02
Amyloid plaques are pathological hallmarks of Alzheimer's disease (AD) -- clumps of misfolded proteins that accumulate in the brain, disrupting and killing neurons and resulting in the progressive cognitive impairment that is characteristic of the widespread neurological disorder.
In a new study, published March 2, 2021 in the Journal of Experimental Medicine (JEM), researchers at University of California San Diego School of Medicine, Massachusetts General Hospital and elsewhere have identified a new drug that could prevent AD by modulating, rather than inhibiting, a key enzyme involved ...
A quantum internet is closer to reality, thanks to this switch
2021-03-02
WEST LAFAYETTE, Ind. -- When quantum computers become more powerful and widespread, they will need a robust quantum internet to communicate.
Purdue University engineers have addressed an issue barring the development of quantum networks that are big enough to reliably support more than a handful of users.
The method, demonstrated in a paper published in Optica, could help lay the groundwork for when a large number of quantum computers, quantum sensors and other quantum technology are ready to go online and communicate with each other.
The team deployed a programmable switch to adjust how much data goes to each ...
Scientists use forest color to gauge permafrost depth
2021-03-02
Scientists regularly use remote sensing drones and satellites to record how climate change affects permafrost thaw rates -- methods that work well in barren tundra landscapes where there's nothing to obstruct the view.
But in boreal regions, which harbor a significant portion of the world's permafrost, obscuring vegetation can stymy even the most advanced remote sensing technology.
In a study published in January, researchers in Germany and at the University of Alaska Fairbanks' Geophysical Institute developed a method of using satellite imagery to measure the depth of thaw directly above permafrost in boreal ecosystems. Rather than trying to peer past ...
A genetic patch to prevent hereditary deafness
2021-03-02
They can hear well up to about forty years old, but then suddenly deafness strikes people with DFNA9. The cells of the inner ear can no longer reverse the damage caused by a genetic defect in their DNA. Researchers at Radboud university medical center have now developed a "genetic patch" for this type of hereditary deafness, with which they can eliminate the problems in the hearing cells. Further research in animals and humans is needed to bring the genetic patch to the clinic as a therapy.
Hereditary deafness can manifest itself in different ways. Often the hereditary defect (mutation) immediately causes deafness from birth. Sometimes, as with DFNA9, you experience the initial ...
Deep immune profiling shows significant immune activation in children with MIS-C
2021-03-02
Philadelphia, March 2, 2021--Taking the first deep dive into how the immune system is behaving in patients with multisystem inflammatory syndrome in children (MIS-C), researchers at Children's Hospital of Philadelphia (CHOP) and the Perelman School of Medicine at the University of Pennsylvania have found that children with this condition have highly activated immune systems that, in many ways, are more similar to those of adults with severe COVID-19. The results, published today in Science Immunology, show that better understanding the immune activation in patients with MIS-C could not only help better treat those patients but also improve treatment for adults with ...
Study of severe pediatric COVID-19 syndrome highlights differences in immune responses to SARS-CoV-2
2021-03-02
A new study of patients with Multisystem Inflammatory Syndrome in Children (MIS-C), a rare but severe complication of COVID-19 in children, reveals distinct immune features of COVID-19 not seen in adults that may clue scientists in to why SARS-CoV-2 infection manifests differently in children compared with adults. Their results showed that although the immune landscape in pediatric COVID-19 was similar to that in adults, MIS-C patients uniquely exhibited increased activation of a blood vessel-patrolling CD8+ killer T cell subset, and all pediatric COVID-19 patients harbored greater B cell frequencies for a more prolonged period of time than observed in healthy adults. MIS-C is characterized by pervasive inflammation, an array of symptoms ranging from fever ...

Deepwater Horizon's long-lasting legacy for dolphins
2021-03-02
The Deepwater Horizon disaster began on April 20, 2010 with an explosion on a BP-operated oil drilling rig in the Gulf of Mexico that killed 11 workers. Almost immediately, oil began spilling into the waters of the gulf, an environmental calamity that took months to bring under control, but not before it became the largest oil spill in the history of the petroleum industry.
Nearly 10 years have passed since then, and the oil slick has long since dispersed. Yet, despite early predictions, area wildlife are still feeling the effects of that oil, and research published in Environmental Toxicology and Chemistry has shown that negative health impacts have befallen not only dolphins alive at the time of the spill, but also in their young, born years later.
A team of researchers, including ...
Yale team finds dozens of genes that block regeneration of neurons
2021-03-02
When central nervous system cells in the brain and spine are damaged by disease or injury, they fail to regenerate, limiting the body's ability to recover. In contrast, peripheral nerve cells that serve most other areas of the body are more able to regenerate. Scientists for decades have searched for molecular clues as to why axons -- the threadlike projections which allow communication between central nervous system cells -- cannot repair themselves after stroke, spinal cord damage, or traumatic brain injuries.
In a massive screen of 400 mouse genes, Yale School of Medicine ...
Disruption of lung biological clock in premature babies may raise later flu risk
2021-03-02
Disruptions in the circadian rhythms in lung cells may explain why adults who survived premature birth are often more at risk of severe influenza infections, suggests a study in mice published today in eLife.
Dramatic improvements in the care of infants born prematurely have allowed many more to survive into adulthood. Yet ex-preemies can face several long-term side effects of the life-saving care they received. The study suggests potential new approaches to treating lasting lung problems in those born prematurely.
Many premature infants are not able to breathe on their own and require oxygen to survive. ...
Study: Using a warmer tone in college syllabi makes students more likely to ask for help
2021-03-02
College course syllabi written in a warm, friendly tone are more likely to encourage students to reach out when they are struggling or need help, a new study from Oregon State University found.
Conversely, when a syllabus is written in a more cold, detached tone, students are less likely to reach out.
The study also compared the effect of syllabus tone with the effect of a deliberate "Reach out for help" statement included in the document.
"The instructor has to ask themselves, what's the first point of contact with the class for the student? In an online class and in remote learning, the syllabus is often the ...
Rating tornado warnings charts a path to improve forecasts
2021-03-02
The United States experiences more tornadoes than any other country, with a season that peaks in spring or summer depending on the region. Tornadoes are often deadly, especially in places where buildings can't withstand high winds.
Accurate advanced warnings can save lives. A study from the University of Washington and the National Oceanic and Atmospheric Administration describes a new way to rate and possibly improve tornado warnings. It finds that nighttime twisters, summer tornadoes and smaller events remain the biggest challenges for the forecasting community.
"This new method lets us measure how forecast skill is improving, decreasing or staying the same in different situations," said Alex ...
Study highlights pitfalls associated with 'cybervetting' job candidates
2021-03-02
A recent study of how human resources professionals review online information and social media profiles of job candidates highlights the ways in which so-called "cybervetting" can introduce bias and moral judgment into the hiring process.
"The study drives home that cybervetting is ultimately assessing each job candidate's moral character," says Steve McDonald, corresponding author of the study and a professor of sociology at North Carolina State University. "It is equally clear that many of the things hiring professionals are looking at make it more likely for ...

Oregon researchers unveil the weaving fractal network of connecting neurons
2021-03-02
EUGENE, Ore. - March 2, 2021 - High-resolution imaging and 3D computer modeling show that the dendrites of neurons weave through space in a way that balances their need to connect to other neurons with the costs of doing so.
The discovery, reported in Nature Scientific Reports Jan. 27, emerged as researchers sought to understand the fractal nature of neurons as part of a University of Oregon project to design fractal-shaped electrodes to connect with retinal neurons to address vision loss due to retinal diseases.
"The challenge in our research has been understanding how the neurons we want to target in the retina will connect to our electrodes," said Richard Taylor, a professor and head ...
Law enforcement seizures of methamphetamine and marijuana rose during pandemic
2021-03-02
An analysis of law enforcement seizures of illegal drugs in five key regions of the United States revealed a rise in methamphetamine and marijuana (cannabis) confiscations during the COVID-19 pandemic. Seizures of the two drugs were higher at their peak in August 2020 than at any time in the year prior to the pandemic. While investigators found that trends in heroin, cocaine and fentanyl seizures were not affected by the pandemic, provisional overdose death data show that the increased drug mortality seen in 2019 rose further through the first half of 2020.
The findings suggest that the pandemic and its related restrictions may ...
COVID-19 spread tracked via a rapid, large-scale early wastewater surveillance alert system
2021-03-02
Washington, DC-- March 2, 2021 -- Detecting COVID-19 outbreaks before they spread could help contain the virus and curb new cases within a community. This week in mSystems, an open-access Journal of the American Society for Microbiology, researchers from the University of California San Diego describe a mostly-automated early alert system that uses high-throughput analysis of wastewater samples to identify buildings where new COVID-19 cases have emerged--even before infected people develop symptoms.
The approach is fast, cost-effective, and sensitive enough to detect a single ...
