New research by the team from Wits, with collaborators from the University of Cape Town and University of Pretoria, reveals what a shift from night-time to daytime activity means for the well-being of aardvarks in a warming and drying world.
Due to climate changes, many regions are experiencing increasingly warmer and dryer summers, followed by heavy rain. New study shows this is a fatal combination that can cause massive fish kills in lakes within a few hours.
Archaeological glass contains information about the movement of goods and ancient economies, yet the understanding of critical aspects of the ancient glass industry is fragmentary. Until now, it has been challenging to scientifically determine the origin of the colourless and clear glass, which was particularly favoured by the Romans. The Romans distinguished between two types of clear glass: Alexandrian and Levantine. Now researchers have found a way to localize the furnaces of the two types.
Researchers in Japan have revealed that DNA methylation occurs in the serotonin transporter gene that regulates neurotransmitter transmission in schizophrenia and bipolar patients. Particularly prominent in males and patients with certain genetic polymorphisms, this methylation is inversely correlated to amygdala volume. This work is expected to lead to a better understanding of the pathophysiology of schizophrenia and bipolar disorder. It may also help to develop therapeutic agents and diagnostic/therapeutic...

Contrary to popular views, parental smartphone use is rarely associated with poor parenting, and more often than not, tends to be associated with warm and attached parenting.
New study of 2,500 Dutch children is the first to explore the relationship between brain volume and different doses of radiofrequency electromagnetic fields
The nanoparticle targets only leukemic cells and therefore would reduce the severe adverse effects of current treatments. The receptor for this nanoparticle is expressed in 20 types of cancer and associated with a poor prognosis, so this drug could open a new therapeutic pathway for other tumors.
How to substantially improve sensitizing ability of photosensitisers (PSs) through balancing its excited state lifetime and redox driving force represents a key role in promoting electron transfer efficiency and further enhancing photoconversion efficiency, however remains a great challenge. In this work, for the first time, researchers report a facile strategy to improve sensitizing ability via finely tuning the excited state of Ru(II)-PSs (Ru-1-Ru-4) for boosting CO2 photoreduction.
According to the latest UN report, the number of displaced persons and refugees has surged, again, by several millions. Most of them will not be able to return to their homes in the foreseeable future. Psychologists at Münster University have developed a model of the psychological factors affecting the successful integration of refugees. The model has been published in the journal "Perspectives on Psychological Science".
Researchers at the University of Tsukuba quantified the collective action of small schools of fish using information theory. They found that groups of three act very differently compared with groups of just two. This work may help solve longstanding problems in complexity theory and allow for a clearer model of emergent behavior.
A new University of Alaska-led study provides the first evidence that declines in many of Alaska's chinook salmon populations can be attributed in part to climate-driven changes in their freshwater habitats.
Using artificial intelligence, researchers analysed hundreds of thousands of posts from a 6-month period last year, and found that a large portion of Instagram posts are promoting controversial flavoured e-liquids to young audiences
Using Kyoto University's new 3.8M Seimei Telescope, in collaboration with the National Astronomical Observatory of Japan, astronomers succeeded in detecting 12 stellar flare phenomena on AD Leonis. One of these flares was 20 times larger than those emitted by our own sun, categorizing it a 'superflare'. Subsequent data analysis presents new insight into these explosive phenomena.
The lightning data can serve as an indicator for hazardous weather phenomena and improve short-term forecasting,
Researchers at the Francis Crick Institute have characterised the structure of the SARS-CoV-2 spike protein as well as its most similar relative in a bat coronavirus. The structures provide clues about how the spike evolved and could help inform vaccine design.
A new study from McGill University shows that increases in the concentrations of blood sodium can have an influence on the biological clock of mice, opening new research avenues for potentially treating the negative effects associated with long distance travel or shift work.
Researchers at the University of Westminster and City University of London analysing the music record choices of guests on BBC Radio 4's Desert Island Discs programme has found that the music we listen to between the age of 10 and 30 define us for the rest of our lives.
How does evolution impact ecological patterns? It helps smooth out the rough edges, says UConn Ecology and Evolutionary Biology Professor Mark Urban. Urban led an international team of researchers through a review of the history of ecological and evolutionary research to establish a framework to better understand evolution's impact on ecosystem patterns. The research is published as a perspective in the Proceeding of the National Academy of Sciences.
Johns Hopkins Kimmel Cancer Center investigators report they have uncovered a new mechanism by which invasive breast cancer cells evade the immune system to metastasize, or spread, to other areas of the body.
Curtin University researchers have discovered a new way to more accurately analyse microscopic samples by essentially making them 'glow in the dark', through the use of chemically luminescent molecules. Lead researcher Dr Yan Vogel from the School of Molecular and Life Sciences said current methods of microscopic imaging rely on fluorescence, which means a light needs to be shining on the sample while it is being analysed. While this method is effective, it also has some drawbacks
A survey conducted in the U.K. suggests that social and physical distancing measures put in place during the Covid-19 pandemic significantly impacted people's perception of how quickly time passed compared to their pre-lockdown perceptions. Ruth S. Ogden of Liverpool John Moores University, U.K., presented these findings in the open-access journal PLOS ONE on July 6, 2020.
In a recent study of genes involved in brain functioning, their previously unknown features have been uncovered by bioinformaticians from the Moscow Institute of Physics and Technology and the Institute of Mathematical Problems of Biology, RAS.
New experiences of sexual, emotional and physical abuse at the hands of a romantic partner during the early months of parenthood are associated with increasing symptoms of trauma such as anxiety, depression, self-harm and sleep disorders, researchers report. Having experienced abuse in childhood appears to worsen the impact of current abuse on those symptoms.
The analysis of Tropical Cyclone Cristina's cloud top temperatures revealed some bands of thunderstorms were developing and wrapping around the center of the storm's circulation.
With more than 140 SARS-CoV-2 vaccines in development, the race is on for a successful candidate to help prevent COVID-19. An effective and safe vaccine would be a major advance in the fight against COVID-19. However, there are challenges in evaluating the efficacy of these vaccines during the pandemic, as an analysis article outlines in CMAJ (Canadian Medical Association Journal).
