A team of Northwestern University materials science researchers have developed a new method to view the dynamic motion of atoms in atomically thin 2D materials. The imaging technique, which reveals the underlying cause behind the performance failure of a widely used 2D material, could help researchers develop more stable and reliable materials for future wearables and flexible electronic devices.
Researchers at the University of Maryland, Baltimore County (UMBC) have developed do-it-yourself (DIY) assistive technology prototypes that are revolutionizing how people with disabilities can access tools that will help them interact with the world.
We've all shared the frustration -- software updates that are intended to make our applications run faster inadvertently end up doing just the opposite. These bugs, dubbed in the computer science field as performance regressions, are time-consuming to fix since locating software errors normally requires substantial human intervention.
For many, wastewater is simply contaminated, bacteria-filled water, but it is actually a valuable research resource. The water contains a wealth of information about e.g., the type of antimicrobial resistant bacteria and disease-causing microorganisms that are present in people in the collection area.
Just as people tend to become stuck in their ways as they grow older so too do cells. Neurons in the brain don't one day decide to become heart cells; skin cells repair wounds with skin cells rather than kidney cells.
Cancer cells, on the other hand, are like perpetual teenagers. They're constantly trying on different identities and roles, which is partly what makes them so hard to control.
Women aged 50-70 are more likely than younger women to consume alcohol at levels that exceed low risk drinking guidelines - and most think that's just perfectly fine.
New Edith Cowan University (ECU) research has found that despite the potential health risks of exceeding national drinking guidelines, many middle-aged and young-old women who consume alcohol at high risk levels tend to perceive their drinking as normal and acceptable, so long as they appear respectable and in control.
A simple mechanism, previously known from bacteria, ensures that the immune system strikes a balance between the rapid expansion of immune cells and the prevention of an excessive self-damaging reaction after an infection. This has now been deciphered by scientists at the University Hospital of Freiburg (Germany) and colleagues from the Netherlands and Great Britain. An infection quickly activates T-cells, which leads to their proliferation.
COLUMBUS, Ohio - When it comes to entertainment, people enjoy seeing bad guys get their punishment more than seeing them be forgiven, a new study reveals.
But even though they don't enjoy the forgiveness stories as much, people do find these narratives more meaningful and thought-provoking than ones in which the bad guys receive their just deserts.
A growing health crisis fueled by synthetic chemicals known as per- and polyfluoroalkyl substances, or PFAS, in groundwater has garnered much attention in the last few years.
The reported levels could be "just the tip of the iceberg," as most of the chemicals are still migrating down slowly through the soil, according to Bo Guo, University of Arizona assistant professor of hydrology and atmospheric sciences.
A research team at KAIST reported clinically accurate multiplexed electrical biosensor for detecting Alzheimer's disease by measuring its core biomarkers using densely aligned carbon nanotubes.
Alzheimer's disease is the most prevalent neurodegenerative disorder, affecting one in ten aged over 65 years. Early diagnosis can reduce the risk of suffering the disease by one-third, according to recent reports. However, its early diagnosis remains challenging due to the low accuracy but high cost of diagnosis.
When we predict future climate, it is important to understand the climate of the past. We do. Mostly. Some details are still debatable.
An example of that are the periodicities of ice ages - that is, how ice ages come and go. This is described in a theory developed by amongst others the astronomer Milankovitch in the 1920ies. The theory describes mathematically how incoming radiation from the sun varies over time because the orbit of the Earth around the sun is elliptical and our dear planet wobbles like a top.
Men who are taller in young adulthood, as an indicator of early-life circumstances, may have a lower risk of dementia in old age, suggests a study published today in eLife.
Finding ways to identify individuals at risk of dementia is essential. It can help people take preventive measures or plan for their future care. The study, originally posted on bioRxiv*, indicates that young adult height might be one potential risk factor to consider.
New insight on how a butterfly species developed the ability to adjust its wing eyespot size in response to temperature has been published today in eLife.
An innovative manufacturing technique developed by KAUST researchers has led to the development of hybrid organic transistors for use in next-generation electronic displays and large-area electronics.
Thin-film transistors (TFTs) made from metal oxides have useful properties, including optical transparency and high charge-carrying capacity, and they are increasingly being used in organic light-emitting diode displays.
Philadelphia, February 11, 2020 - Adolescents with a history of attention-deficit/hyperactivity disorder (ADHD) are at an increased risk for a multitude of adverse outcomes, including sexually-transmitted infections (STIs), mental health conditions, and car accidents. Researchers from Children's Hospital of Philadelphia (CHOP) wanted to better understand how primary care doctors addressed these risks with patients as they transitioned from childhood to young adulthood.
