Parents abused as children may pass on emotional issues
2021-05-25
Childhood abuse and trauma are linked to many health issues in adulthood. New research from the University of Georgia suggests that a history of childhood mistreatment could have negative ramifications for the children of people who experienced abuse or neglect in childhood.
Teaching your children how to manage their emotions is an integral part of parenting. For people who experienced childhood abuse, that can become a difficult task. People who were frequently mistreated as children may find it hard to identify their emotions and implement strategies to regulate them. This difficulty, in turn, can harm their kids' emotional development.

"The eROSITA has been designed to study the large-scale structure of the universe and test cosmological models, including dark energy, by detecting galaxy clusters with redshifts greater than 1, corresponding to a cosmological expansion ...
Made in the shade or fun in the sun
2021-05-25
Plants contain several types of specialized light-sensitive proteins that measure light by changing shape upon light absorption. Chief among these are the phytochromes.
Phytochromes help plants detect light direction, intensity and duration; the time of day; whether it is the beginning, middle or end of a season; and even the color of light, which is important for avoiding shade from other plants. Remarkably, phytochromes also help plants detect temperature.
New research from Washington University in St. Louis helps explain how the handful of phytochromes found in every plant respond differently to light intensity and temperature, thus ...
Study examines how pandemic-related changes affect college students' motivation
2021-05-25
CHAMPAIGN, Ill. -- When the worsening COVID-19 pandemic prompted colleges to shutter their campuses and shift to remote learning in spring 2020, concerns arose that many underrepresented students in science, technology, engineering and mathematics disciplines would be demotivated and drop out in even greater numbers.
However, a study of 182 undergraduate students in a biology course at one university found little evidence to support that belief. Instead, across all demographic groups, the impact varied: Some students were more motivated, some were less so, and some saw no changes ...

AI spots neurons better than human experts
2021-05-25
DURHAM, N.C. -- A new combination of optical coherence tomography (OCT), adaptive optics and deep neural networks should enable better diagnosis and monitoring for neuron-damaging eye and brain diseases like glaucoma.
Biomedical engineers at Duke University led a multi-institution consortium to develop the process, which easily and precisely tracks changes in the number and shape of retinal ganglion cells in the eye.
This work appears in a paper published on May 3 in the journal Optica.
The retina of the eye is an extension of the central nervous system. Ganglion cells are one of the primary neurons in the eye that process and send visual information to the brain. In many neurodegenerative ...
Can TV shows help teens navigate bullying, depression and other mental health issues?
2021-05-25
Popular television shows and movies can bolster teenagers' mental health and help them cope with bullying, sexual assault, suicidal thoughts, substance abuse and depression when these issues are depicted with empathy and appropriate resources are provided, a report published by UCLA's Center for Scholars and Storytellers shows.
And the need is great. Recent research has shown that children between the ages of 11 and 17 are more likely than any other age group to report moderate to severe anxiety and depression, said Yalda Uhls, founder and executive director of the center and an adjunct assistant professor of psychology.
Even before the pandemic, teen suicide rates were rising, along with reported symptoms of anxiety and depression, she noted. At the same time, nearly half ...

Newly discovered enzymes are not heavy metal fans
2021-05-25
Tsukuba, Japan - Carbonic anhydrases are essential enzymes that are present in virtually all living things; all eight classes of carbonic anhydrases that have been identified to date need a metal ion to function. But now, researchers from Japan have discovered that metal is not crucial for all carbonic anhydrases.
In a study published this month in BMC Biology, researchers from the Faculty of Life and Environmental Sciences at the University of Tsukuba have described two members of the COG4337 protein family that are the first known examples of carbonic anhydrase enzymes that do not require a metal ion to function.

Food scraps get a bold new life
2021-05-25
Tokyo, Japan - Most people don't think much about the food scraps they throw away; however, investigators from the Institute of Industrial Science at The University of Tokyo have developed a new method to reduce food waste by recycling discarded fruit and vegetable scraps into robust construction materials.
Worldwide industrial and household food waste amounts to hundreds of billions of pounds per year, a large proportion of which comprises edible scraps, like fruit and vegetable peels. This unsustainable practice is both costly and environmentally unfriendly, so researchers have been searching for new ways to recycle these organic ...
New technique breaks the mould for 3D printing medical implants
2021-05-25
Researchers have flipped traditional 3D printing to create some of the most intricate biomedical structures yet, advancing the development of new technologies for regrowing bones and tissue.
The emerging field of tissue engineering aims to harness the human body's natural ability to heal itself, to rebuild bone and muscle lost to tumours or injuries.
A key focus for biomedical engineers has been the design and development of 3D printed scaffolds that can be implanted in the body to support cell regrowth.
But making these structures small and complex enough for cells to thrive remains a significant challenge.
Enter a RMIT University-led research team, collaborating with clinicians at St Vincent's Hospital Melbourne, Australia, who have overturned ...
Pain monitoring helps assess the effectiveness of opioid-sparing approaches during surgery
2021-05-25
A new study has shown that effective opioid-sparing anaesthesia with dexmedetomidine can be guided with NOL pain monitoring technology (Medasense, Israel). The study showed that the NOL monitor is able to detect the effect of dexmedetomidine on the patient's pain response and enable administration of less intraoperative opioids.
Patients undergoing anaesthesia for surgical procedures are traditionally treated with opioids (e.g., remifentanil) to manage intraoperative pain. But clinicians are progressively seeking to reduce opioid use by introducing multimodal analgesia, a technique that involves a combination of medications that often includes a central ...
Superoxide produced in the cochlea of inner ears causes acquired hearing loss
2021-05-25
Professor UEYAMA Takehiko (Biosignal Research Center, Kobe University) and the inner ear research group (Kyoto Prefectural University of Medicine) have identified the cell types in the inner ear cochlea (*1) responsible for the production of superoxide (Nox3*2-expressing cells). They achieved this by using genetically modified mice that they developed. The researchers discovered that these superoxide-producing cells increase in number in response to aging, noise damage, and ototoxic drugs, thus causing age-related, noise-induced and drug-induced hearing loss. In addition, they were able to suppress the onset of these three types of ...
Decreased testing could lead to surge in sexually transmitted infections
2021-05-25
HERSHEY, Pa. -- Screening and testing for sexually transmitted infections (STIs) decreased by 63% for men and 59% for women during the early months of the COVID-19 pandemic, according to a new study led by Penn State and Quest Diagnostics researchers. The researchers said this may be the result of restrictions placed on direct patient care and shifts to telehealth and could lead to a possible future surge in STI cases.
This is the first national study to explore the impact of the pandemic on STIs since the Centers for Disease Control and Prevention ...
Scientific software - Quality not always good
2021-05-25
Computational tools are indispensable in almost all scientific disciplines. Especially in cases where large amounts of research data are generated and need to be quickly processed, reliable, carefully developed software is crucial for analyzing and correctly interpreting such data. Nevertheless, scientific software can have quality quality deficiencies. To evaluate software quality in an automated way, computer scientists at Karlsruhe Institute of Technology (KIT) and Heidelberg Institute for Theoretical Studies (HITS) have designed the SoftWipe tool.
"Adherence to coding standards is rarely considered in scientific software, although it can even lead to incorrect scientific results," says ...

New AI technology protects privacy
2021-05-25
Digital medicine is opening up entirely new possibilities. For example, it can detect tumors at an early stage. But the effectiveness of new AI algorithms depends on the quantity and quality of the data used to train them.
To maximize the data pool, it is customary to share patient data between clinics by sending copies of databases to the clinics where the algorithm is being trained. For data protection purposes, the material usually undergoes anonymization and pseudonymization processes - a procedure that has also come in for criticism. "These processes have often proven inadequate in terms of protecting patients' health data," says Daniel Rueckert, ...
Is deference to supernatural beings present in infancy?
2021-05-25
From shamans and mystics to cult leaders and divine kings, why have people throughout history accorded high status to people believed to have supernatural powers?
According to a study led by researchers from the University of Oxford, this tendency to attribute social dominance to such individuals is rooted in early development.
As part of the study, 48 infants aged 12 to 16 months watched a series of animated videos in which two characters competed for a reward. In each scenario, one character displayed physically counterintuitive methods of making ...

Immune cells imperfect at distinguishing between friend and foe, study suggests
2021-05-25
When it comes to distinguishing a healthy cell from an infected one that needs to be destroyed, the immune system's killer T cells sometimes make mistakes.
This discovery, described today in eLife, upends a long-held belief among scientists that T cells were nearly perfect at discriminating friend from foe. The results may point to new ways to treat autoimmune diseases that cause the immune system to attack the body, or lead to improvements in cutting-edge cancer treatments.
It is widely believed that T cells can discriminate perfectly between infected cells and healthy ones based on how tightly they are able to bind to molecules called antigens ...
Study reveals new details on what happened in the first microsecond of Big Bang
2021-05-25
About 14 billion years ago, our universe changed from being a lot hotter and denser to expanding radically - a process that scientists have named 'The Big Bang'.
And even though we know that this fast expansion created particles, atoms, stars, galaxies and life as we know it today, the details of how it all happened are still unknown.
Now a new study performed by researchers from University of Copenhagen reveals insights on how it all began.
"We have studied a substance called Quark-Gluon Plasma that was the only matter, which existed during the first microsecond ...
Impaired dopamine transporters contribute to Parkinson's disease-like symptoms
2021-05-25
A rare mutation that causes Parkinson's disease-like symptoms interrupts the flow of dopamine in the brain, suggests a study in fruit flies published today in eLife.
The findings provide more detailed insights about why young children with this mutation develop these symptoms. This new information, as well as previous evidence that therapies helping to improve dopamine balance in the brain can alleviate some symptoms in the flies, suggests that this could be a beneficial new treatment strategy.
Parkinson's disease causes progressive degeneration of the brain that leads to impaired movement and coordination. Current treatments focus on replacing or increasing the levels of dopamine to help reduce movement-related symptoms. But these drugs can have side ...
"Bite" defects in bottom-up graphene nanoribbons
2021-05-25
Graphene nanoribbons (GNRs), narrow strips of single-layer graphene, have interesting physical, electrical, thermal, and optical properties because of the interplay between their crystal and electronic structures. These novel characteristics have pushed them to the forefront in the search for ways to advance next-generation nanotechnologies.
While bottom-up fabrication techniques now allow the synthesis of a broad range of graphene nanoribbons that feature well-defined edge geometries, widths, and heteroatom incorporations, the question of whether or not structural disorder is present in these atomically precise GNRs, and to what extent, is still subject to debate. The answer to this ...
