(NASDAQ: TLC) shares shot up on Wednesday after the firm announced that it would be able to move forward with its COVID-19 trial that uses hydroxychloroquine. In the past, hydroxychloroquine has been viewed as a controversial drug in terms of evaluating its efficacy in treating COVID-19, but now there seems to be a definitive ruling on it—at least in Australia and Taiwan.
In terms of the specifics, the company announced the receipt of ethical and scientific approval from the Bellberry Human Research Ethics Committee (HREC) in Australia for the company’s Phase 1 clinical trial of TLC19 hydroxychloroquine liposome inhalation suspension for COVID-19.
The HREC is constituted in accordance with the requirements of the National Health & Medical Research Council (NHMRC), and it reviews clinical trial proposals to ensure that they are ethically and scientifically acceptable and have
A National Institutes of Health study in mice suggests that parents have an innate capacity to respond to an infant’s cries for help and this capacity may serve as a foundation from which a parent learns to adjust to an infant’s changing needs. The study was conducted by Robert C. Froemke, Ph.D., of New York University School of Medicine, and colleagues. It appears in Nature.
When housed with mice who have given birth, unmated female mice will assist with the care of the newborn pups. The researchers evaluated the ability of such babysitter mice to respond to a variety of recorded newborn distress cries. These included typical distress cries as well as a range of cries that had been digitally altered — sped up or slowed down to include more or fewer syllables than typical distress vocalizations.
Experienced babysitters responded to typical distress cries 80% of the time, compared
An international research team including the University of Adelaide has found further evidence that rare gene mutations can cause cerebral palsy, findings which could lead to earlier diagnosis and new treatments for this devastating movement disorder.
In the study published in the journal Nature Genetics researchers employed gene sequencing to examine the DNA of 250 cerebral palsy families, and compared this to a control group of almost 1800 unaffected families. They then demonstrated the impact rare gene mutations can have on movement control using a fruit fly model.
The findings have important clinical implications. They will provide some answers to parents, as well as guide healthcare and family planning such as counselling for recurrence risk — often quoted as around 1 per cent but could be as high as 10 per cent when factoring in genetic risks.

Working with fish, birds and mice, Johns Hopkins Medicine researchers report new evidence that some animals’ natural capacity to regrow neurons is not missing, but is instead inactivated in mammals. Specifically, the researchers found that some genetic pathways that allow many fish and other cold-blooded animals to repair specialized eye neurons after injury remain present in mammals as well, but are turned off, blocking regeneration and healing.
A description of the study, published online by the journal Science on Oct. 1, offers a better understanding of how genes that control regeneration are conserved across species, as well as how they function. This may help scientists develop ways to grow cells that are lost due to hereditary blindness and other neurodegenerative diseases.
“Our research overall indicates that the potential for regeneration is there in mammals, including humans, but some evolutionary pressure has turned it off,” says Seth Blackshaw, Ph.D., professor of
Brain cells have been found in exceptionally preserved form in the remains of a young man killed in the eruption of Mount Vesuvius almost 2,000 years ago, an Italian study has revealed.
The preserved neuronal structures in vitrified or frozen form were discovered at the archaeological site of Herculaneum, an ancient Roman city engulfed under a hail of volcanic ash after nearby Mount Vesuvius erupted in the year 79.

“The study of vitrified tissue as the one we found at Herculaneum… may save lives in future,” study lead author Pier Paolo Petrone, forensic anthropologist at Naples’ University Federico II, told AFP in English.
“The experimentation continues on several research fields, and the data and information we are obtaining will allow us to clarify other and newer aspects of what happened 2000 years ago during
Rising nitrous oxide (N2O) emissions are jeopardizing the climate goals of the Paris Agreement, according to a major new study by an international team of scientists.
The growing use of nitrogen fertilizers in the production of food worldwide is increasing atmospheric concentrations of N2O—a greenhouse gas 300 times more potent than carbon dioxide (CO2) that remains in the atmosphere for more than 100 years.
Published today in the journal Nature, the study was led Auburn University, in the US, and involved scientists from 48 research institutions in 14 countries—including the University of East Anglia (UEA) in the UK—under the umbrella of the Global Carbon Project and the International Nitrogen Initiative.
The aim was to produce the most comprehensive assessment to date of all global sources and sinks of N2O. Their findings show N2O emissions are
Researchers know that texting programs can greatly benefit young children’s literacy. Now new research shows that parents’ participation in such programs can be boosted exponentially with one simple tweak: automatic enrollment, combined with the ability to opt out.
The new research from the Center for Child and Family Policy at Duke University’s Sanford School of Public Policy appears in the Journal of Child and Family Studies.
In recent years, mounting research evidence has shown texting to be an effective, low-cost, scalable approach for engaging parents in their children’s learning. Some studies suggest text message interventions via tips for parents on how to support their child’s development can put young children’s learning 2-3 months ahead.
Yet getting parents to enroll in these beneficial programs can be challenging. With that in mind, researchers designed a study to test strategies for increasing program participation.
Challenging a 75-year-old notion about how and when reptiles evolved during the past 300 million-plus years involves a lot of camerawork, loads of CT scanning, and, most of all, thousands of miles of travel. Just check the stamps in Tiago R. Simões ‘ passport.
Simões is the Alexander Agassiz Postdoctoral Fellow in the lab of Harvard paleontologist Stephanie Pierce. From 2013 to 2018, he traveled to more than 20 countries and more than 50 different museums to take CT scans and photos of nearly 1,000 reptilian fossils, some hundreds of millions of years old. It amounted to about 400 days of active collection, helping form what is believed to be the largest available timeline on the evolution of major living and extinct reptile groups.
Now, a statistical analysis of that vast database is helping scientists better understand the evolution of these cold-blooded vertebrates by contradicting a widely held theory that
Because of the COVID-19 pandemic, most universities across the United States transitioned from face-to-face classes to remote learning, closed campuses and sent students home this past spring. Such changes, coupled with social distancing guidelines, have altered social interactions and limited our access to fitness facilities, parks and gymnasiums. This is concerning as positive social interaction and access to exercise facilities both promote physical activity. Recently, a group of Kent State University researchers sought to examine the impact of these pandemic-related changes upon physical activity and sedentary behavior, specifically sitting, across the university population.
Kent State’s College of Education, Health and Human Services professors Jacob Barkley, Ph.D., Andrew Lepp, Ph.D., and Ellen Glickman, Ph.D., along with current and former Kent State doctoral students Greg Farnell, Ph.D., Jake Beiting, Ryan Wiet and Bryan Dowdell, Ph.D., assessed the impact of the COVID-19 pandemic on physical activity and sedentary behavior. More than 400 college
The loss of flowering plants and the widespread use of pesticides could be a double punch to wild bee populations. In a new study, researchers at the University of California, Davis, found that the combined threats reduced blue orchard bee reproduction by 57 percent and resulted in fewer female offspring. The study was published in the journal Proceedings of the Royal Society B.
“Just like humans, bees don’t face one single stress or threat,” said lead author Clara Stuligross, a Ph.D. candidate in ecology at UC Davis. “Understanding how multiple stressors interplay is really important, especially for bee populations in agricultural systems, where wild bees are commonly exposed to pesticides and food can be scarce.”
The study found that pesticide exposure had the greatest impact on nesting activity and the number of offspring the bees produced. Pesticide exposure reduced bee reproduction 1.75 times more than limiting their food.
