Research pioneer Dr. Daniel Drucker has much to be proud of, as the GLP-1-based diabetes drugs hailing from his early research are named 2023 breakthrough of the year by the Science Magazine. Not only have millions of people with type 2 diabetes benefitted from GLP-1 agonists, but the drugs also produced wide-ranging health benefits beyond weight loss in two recent patient trials. For years, GLP-1 agonists have been known to have a fortuitous side effect of improving metabolic health, but how this is regulated in the body remains unclear. Now Dr. ...

Ecological restoration may save coral atoll islands from the rising seas of climate change, according to an international team of scientists, conservationists, and an indigenous leader.   While global carbon emission reduction is imperative, local measures could be the key to the islands outpacing sea levels, they argue today in the journal Trends in Ecology & Evolution.   “Far from being doomed, in their natural state most coral atoll islands could adapt to sea level rise”, says Dr Sebastian Steibl from the University of Auckland ...

Researchers at the National Institutes of Health have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the first five days of development, a period in which embryos mature from a single cell into distinct cell types. These diverse cells become tissues and organs that form juvenile fish capable of swimming and looking for food. The findings are published in Developmental Cell. “Perhaps surprisingly, tiny zebrafish provide us with significant insight ...

Estimated to be worth USD 50.1 billion by 2030, a Surrey team of researchers has uncovered the potential of the growing dog-friendly travel market. The Covid-19 pandemic drove an increase in UK household dog ownership, creating a need for tourism providers to adapt to accommodate these four-legged family members.  The Surrey team set out to understand why people travel with their dogs, how they feel about it, and what challenges they face doing so.  Lori Hoy, PhD Researcher and lead author of the study at the University of Surrey, said:  "Some reports suggest that the UK dog population stands at 11 million, with 29% of UK adults having a dog in their ...

In a study comparing human brain communication networks with those of macaques and mice, EPFL researchers found that only the human brains transmitted information via multiple parallel pathways, yielding new insights into mammalian evolution. When describing brain communication networks, EPFL senior postdoctoral researcher Alessandra Griffa likes to use travel metaphors. Brain signals are sent from a source to a target, establishing a polysynaptic pathway that intersects multiple brain regions “like a road with many stops along the way.” She explains that structural brain ...

Photosynthesis refers to the fundamental biological process of the conversion of light energy into chemical energy by chlorophyll (a green pigment) containing plants. This seemingly routine process in plants sustains all the biological life and activities on Earth. First reaction of photosynthesis occurs at a site called photosystem II (PSII), present on the thylakoid membrane in the chloroplast where light energy is transferred to chlorophyll molecules. PSII is made up of a complex group of proteins, including the D1 and D2 reaction center proteins. Light ...

Despite affecting millions worldwide, Alzheimer's disease (AD) has long lacked effective treatments due to a fundamental inadequacy of our understanding of its etiology and pathogenesis. The absence of an integrative theory connecting the molecular origins of AD with disturbances at the organelle and cell levels, changes in relevant biomarkers, and population-level prevalence has hindered progress. Even though most scientists only hope that an integrative theory of AD will emerge soon, scientists from Zarbio and Georgia State University discovered sufficient data to formulate a framework for such a theory. The molecular and cellular ...

CORVALLIS, Ore. – In a first-of-its-kind study of aardvarks, Oregon State University researchers spent months in sub-Saharan Africa collecting poop from the animal and concluded that aridification of the landscape is isolating them, which they say could have implications for their long-term survival. “Everyone had heard of aardvarks and they are considered very ecologically important but there has been little study of them,” said Clint Epps, a wildlife biologist at Oregon State. “We wanted to see if we could collect enough data to begin to understand them.” In ...

(Denver—December 18, 2023) – Adopting a lung nodule program (LNP) may increase the detection of early lung cancer for patients who are not eligible for lung cancer screening under existing age eligibility criteria, according to a study published in the Journal of Thoracic Oncology, an official journal of the International Association for the Study of Lung Cancer. LNPs are established to follow up on lung nodules that are frequently identified during routine imaging for reasons other than suspected lung cancer or lung cancer screening. The research was conducted by a team led by Dr. Raymond U. Osarogiagbon, MBBS, FACP, chief scientist ...

Prenatal diagnosis of congenital heart defects – the most common birth defects in the United States – is associated with improved outcomes. Despite its importance, however, overall prevalence of prenatal diagnosis is low (12-50 percent). A recent multi-center study surveyed caretakers of infants who received congenital heart surgery in the Chicago area and found that social determinants or influencers of health constitute significant barriers to prenatal diagnosis from the patients’ perspective. In ...

In a new analysis of data spanning more than three decades in the eastern United States, a team of scientists found a concerning trend – an increasing number of wildfires across a large swath of America.  “It’s a serious issue that people aren’t paying enough attention to: We have a rising incidence of wildfires across several regions of the U.S., not only in the West,” said Victoria Donovan, lead author of the study and an assistant professor of forest management at the UF/IFAS ...

Long-term care facilities that scheduled part-time Certified Nursing Assistants (CNAs) with more hours and more consistently with the same co-workers had reduced turnover, according to research led by Washington State University. The findings could help address staffing challenges that affect millions of patients at long-term care facilities nationwide.  Using a model based on real scheduling data of thousands of nurse aides, the researchers estimated that a one-hour increase in CNAs’ weekly hours worked could reduce turnover by 1.9%. Also, the analysis found that by scheduling ...

A new landmark study involving 281 elite athletes from Australia and Belgium has revealed one in six have measures that would normally suggest reduced heart function.   Genetic analysis published in Circulation conducted by scientists in Australia and Belgium revealed those athletes also had an enrichment of genes associated with heart muscle disease. Thus, a genetic predisposition may be ‘stressed’ by exercise to cause profound heart changes. The international collaboration will continue to monitor the athletes over the long-term to determine the consequences on their heart health. Associate Professor Andre la Gerche, who heads the HEART Laboratory that is jointly ...

Tempe, Ariz., December 18, 2023 – Extreme heat waves, once considered rare, are now frequent and severe in cities due to climate change. Phoenix faced such a brutal heat wave in July of 2023 when it endured 31 consecutive days of high temperatures of at least 110 F. The severity of the heat wave triggered a state of emergency. In June of 2021, the town of Lytton, B.C., Canada, hit a blistering 121 F, leading to a fire that burnt most of the village. This pattern repeated in Europe in 2022, where heat caused fatal illnesses, wildfires and damaged infrastructure, highlighting ...

Led by Aoxing Liu and senior authors Melinda Mills, Andrea Ganna and an international team, the study examined the link between 414 early-life diseases and lifetime childlessness in over 2.5 million individuals born in Finland and Sweden. In many Western European and East Asian countries, up to 15-20% of individuals born around 1970 are now childless. Although multiple social, economic and individual preferences have been studied, there has been limited research examining the contribution of different diseases to being childless over a lifetime, particularly those diseases with onset prior to the peak reproductive age. Dr Aoxing Liu, lead author ...

CORVALLIS, Ore. – Some coral species can be resilient to marine heat waves by “remembering” how they lived through previous ones, research by Oregon State University scientists suggests. The study, funded by the National Science Foundation, also contains evidence that the ecological memory response is likely linked to the microbial communities that dwell among the corals. The findings, published today in Global Change Biology, are important because coral reefs, crucial to the functioning ...
