During the COVID-19 pandemic, parents have been faced with challenging circumstances to balance work, household, care of children and support of distance learning for school-age children without help from their regular support systems such as schools, childcare, and often other family members as well. A new longitudinal study in Germany examined day-to-day parenting behavior during the restrictions and closures caused by the pandemic from the end of March until the end of April 2020.
Philadelphia, January 19, 2021 - Early life experiences can have an outsized effect on brain development and neurobiological health. New research is showing that those effects can be passed down to subsequent generations, reporting that the infant children of mothers who had experienced childhood emotional neglect displayed altered brain circuitry involved in fear responses and anxiety.
LA JOLLA, CALIF. - Jan 20, 2020 - Scientists have identified two drugs that are potent against acute myeloid leukemia (AML) when combined, but only weakly effective when used alone. The researchers were able to significantly enhance cancer cell death by jointly administering the drugs that are only partially effective when used as single-agent therapies.
ANN ARBOR, Mich. -- An estimated one in five teenagers has symptoms of a mental health disorder such as depression or anxiety, and suicide is the second leading cause of death among teens.
But the first person a teen confides in may not always be an adult - they may prefer to talk to another teen.
Scientists of Tomsk Polytechnic University jointly with colleagues from the University of Lille (Lille, France) synthetized a new material based on reduced graphene oxide (rGO) for supercapacitors, energy storage devices. The rGO modification method with the use of organic molecules, derivatives of hypervalent iodine, allowed obtaining a material that stores 1.7 times more electrical energy. The research findings are published in Electrochimica Acta academic journal (IF: 6,215; Q1).

El Niño or correctly El Niño - Southern Oscillation (ENSO) is the strongest natural climate fluctuation on time scales of a few years. Through ocean and atmosphere interactions, El Niño (Spanish for The Christ Child) events cause significant warming of the eastern Pacific, accompanied by catastrophic rainfall over South America and droughts in the Indo-Pacific region. Powerful events have global effects that reach even into the extra-tropics.
The Gulf of Mexico holds huge untapped offshore oil deposits that could help power the U.S. for decades.
The energy super basin's longevity, whose giant offshore fields have reliably supplied consumers with oil and gas since the 1960s, is the result of a remarkable geologic past - a story that began 200 million years ago among the fragments of Pangea, when a narrow, shallow seaway grew into an ocean basin, while around it mountains rose then eroded away.
Berkeley -- Most frogs emit a characteristic croak to attract the attention of a potential mate. But a few frog species that call near loud streams -- where the noise may obscure those crucial love songs -- add to their calls by visually showing off with the flap of a hand, a wave of a foot or a bob of the head. Frogs who "dance" near rushing streams have been documented in the rainforests of India, Borneo, Brazil and, now, Ecuador.
The Beijing-Arizona Sky Survey (BASS) team of National Astronomical Observatories of Chinese Academy of Sciences (NAOC) and their collaborators of the Dark Energy Spectroscopic Instrument (DESI) project released a giant 2D map of the universe, which paves the way for the upcoming new-generation dark energy spectroscopic survey.
Climate and changes in it have direct impacts on species of plant and animals - but climate may also shape more complex biological systems like food webs. Now a research group from the University of Helsinki has investigated how micro-climate shapes each level of the ecosystem, from species' abundances in predator communities to parasitism rates in key herbivores, and ultimately to damage suffered by plants. The results reveal how climate change may drastically reshape northern ecosystems.
Posidonia oceanica seagrass -an endemic marine phanerogam with an important ecological role in the marine environment- can take and remove plastic materials that have been left at the sea, according to a study published in the journal Scientific Reports. The article's first author is the tenure-track 2 lecturer Anna Sànchez-Vidal, from the Research Group on Marine Geosciences of the Faculty of Earth Sciences of the University of Barcelona (UB).
Bacteria are likely triggering greater melting on the Greenland ice sheet, possibly increasing the island's contribution to sea-level rise, according to Rutgers scientists.
In patients with bladder cancer, chemotherapy effectiveness is partially determined by the body's immune system response to the malignancy. This is the conclusion of research conducted by a team of scientists from Charité - Universitätsmedizin Berlin and the Berlin Institute of Health. The findings, which have been published in Science Translational Medicine*, can be used to predict treatment success and may increase survival in patients with bladder cancer.
Recently, the research team led by academician GUO Guangcan from the University of Science and Technology of China of the Chinese Academy of Sciences has made security analysis and improvement of source independent quantum random number generators with imperfect devices.
In the inaugural issue of the journal Nature Aging a research team led by aging expert Linda P. Fried, MD, MPH, dean of Columbia University Mailman School of Public Health, synthesizes converging evidence that the aging-related pathophysiology underpinning the clinical presentation of phenotypic frailty (termed as "physical frailty" here) is a state of lower functioning due to severe dysregulation of the complex dynamics in our bodies that maintains health and resilience. When severity passes a threshold, the clinical syndrome and its phenotype are diagnosable.
