A international team of astronomers led by Université de Montréal has made an exciting discovery about the temperate exoplanet LHS 1140 b: it could be a promising "super-Earth" covered in ice or water. When the exoplanet LHS 1140 b was first discovered, astronomers speculated that it might be a mini-Neptune: an essentially gaseous planet, but very small in size compared to Neptune. But after analyzing data from the James Webb Space Telescope (JWST) collected in December 2023 - combined with previous data from other space telescopes such as Spitzer, Hubble and ...

SAN FRANCISCO, CA—Genome editing has become a widely adopted technology to modify DNA in cells, allowing scientists to study diseases in the lab and develop therapies that repair disease-causing mutations. However, with current approaches, it’s only possible to edit cells in one location at a time. Now, a team of scientists at Gladstone Institutes has developed a new method that enables them to make precise edits in multiple locations within a cell—all at once. Using molecules called retrons, they created a tool that can efficiently modify DNA in bacteria, yeast, and human cells. “We wanted to push the boundaries of genomic technologies ...

Awarded the 2023 Nobel Prize in Chemistry, quantum dots have a wide variety of applications ranging from displays and LED lights to chemical reaction catalysis and bioimaging. These semiconductor nanocrystals are so small—on the order of nanometers—that their properties, such as color, are size dependent, and they start to exhibit quantum properties. This technology has been really well developed, but only in the visible spectrum, leaving untapped opportunities for technologies in both the ultraviolet and infrared regions of the electromagnetic ...

Certain types of light have proven to be an effective, minimally invasive treatment for cancers located on or near the skin when combined with a light-activated drug. But deep-seated cancers, surrounded by tissue, blood and bone, have been beyond the reach of light’s therapeutic effects. To bring light’s benefits to these harder-to-access cancers, engineers and scientists at the University of Notre Dame have devised a wireless LED device that can be implanted. This device, when combined with a light-sensitive ...

While food insecurity has long been the focus of local and national policymakers and researchers, nutrition insecurity has largely been overlooked. A new study by the Institute for Food System Equity (IFSE) at the USC Dornsife College of Letters, Arts and Sciences aims to change that. This is the first study in Los Angeles County to identify the populations most affected by nutrition insecurity, distinct from food insecurity. Nutrition insecurity refers to a lack of access to healthy food that ...

AI can help humanitarians gain crucial insights to better monitor and anticipate risks, such as a conflict outbreak or escalation. But deploying systems in this context is not without risks for those affected, a new study warns. Humanitarian organisations have been increasingly using digital technologies and the Covid-19 pandemic has accelerated this trend. AI-supported disaster mapping was used in Mozambique to speed up emergency response, and AI systems were used to predict food crisis and rolled out by the World Bank across twenty-one countries. But the study warns some uses of AI may expose people to additional harms and present significant ...

The Office of the Vice President for Research and Innovation at The University of Texas at Arlington has awarded seven Interdisciplinary Research Program (IRP) grants totaling nearly $140,000 to foster collaboration between groups that do not typically work together. This represents an increase in funding of 40% over the grants awarded in 2023. “UT Arlington has increased its support of interdisciplinary research as we know that many of today’s great societal challenges ...

CAMBRIDGE, MA — A new tool makes it easier for database users to perform complicated statistical analyses of tabular data without the need to know what is going on behind the scenes. GenSQL, a generative AI system for databases, could help users make predictions, detect anomalies, guess missing values, fix errors, or generate synthetic data with just a few keystrokes. For instance, if the system were used to analyze medical data from a patient who has always had high blood pressure, it could catch a blood pressure reading that ...

Despite decades of research, there’s still much scholars don’t understand about life’s beginnings and early evolution. A UC Riverside paper has opened the door to understanding more and to framing future studies that could help predict climate change and search for life beyond Earth.   “This paper strives to inform the Earth sciences community where the research needs to go next,” said Christopher Tino, a UCR PhD candidate during the time of research and a first author. Many studies have explored signs ...

Quantum computers offer powerful ways to improve cybersecurity, communications, and data processing, among other fields. To realize these full benefits, however, multiple quantum computers need to be connected to build quantum networks or a quantum internet. Scientists have struggled to come up with practical methods of building such networks, which must transmit quantum information over long distances. Now, researchers at the University of Chicago Pritzker School of Molecular Engineering (PME) have proposed a new approach — building long quantum channels using vacuum sealed tubes ...

“These findings potentially support employing anti-aging therapies such as senolytic pharmacologic compounds to prevent or ameliorate progression to AMD [...]” BUFFALO, NY- July 9, 2024 – A new editorial paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 12, entitled, “Aging retinal pigmented epithelium: omics-based insights into vision decline.” In this new editorial, researchers Ioan V. Matei and Luminita Paraoan from ...

AURORA, Colo. (July 9, 2024) – In the aftermath of the COVID-19 pandemic, the U.S. public health system must focus on critical questions of accountability, politicization and updating data systems if it is to do its job well and maintain the trust of the American people, according to a new report from the Colorado School of Public Health. The report, authored by Professor Jonathan Samet, MD, MS, of the Colorado School of Public Health and Professor Ross Brownson, PhD, of Washington University in St. Louis, was published recently in the journal Health Affairs. In ...

Two University of Oklahoma researchers have been awarded more than $2 million in grants from the Hevolution Foundation to further their studies on age-related cognitive impairment, with an emphasis on improving “health span,” or the number of years a person remains healthy. While modern medicine can help extend a person’s life span, researchers are increasingly studying ways to increase their healthy years of life. Because the process of aging increases the risk for memory problems and dementia, researchers must understand why as a first step toward delaying cognitive issues until later in life. The Hevolution Foundation ...

Irvine, Calif., July 9, 2024 – Exactly how the turbulent mixing of ocean water relates to global overturning circulation has been little understood by oceanographers, but an international research team, including an Earth system scientist at the University of California, Irvine, has found that bumpy topographical features along the sloping ocean floor contribute significantly to ocean seawater upwelling.   In a paper published recently in Nature, the researchers describe a “vigorous near-bottom upwelling” that results in the upward transition of water from denser to lighter ocean layers at a rate ...

Key takeaways Virtually all study respondents on the political left and more than 75% on the right supported allowing children to play with both traditionally “girl” and “boy” toys. Those on both sides of the political spectrum also supported the idea that girls should be able to aspire to traditionally male pursuits. However, while most left-wing activists supported the idea of a child living in a way that does not align with their birth sex, most right-wing activists rejected the idea. Society appears deeply divided on how to parent with regard to gender. For example, some parents throw “gender reveal” ...

Individuals diagnosed with prediabetes can reduce their long-term risk of death and diabetes-related health complications if they delay the onset of diabetes for just four years through diet and exercise. Guangwei Li of the China-Japan Friendship Hospital and colleagues report these findings in a new study published July 9th in the open-access journal PLOS Medicine. Type 2 diabetes is associated with an increased risk of death and disability, and imposes a significant economic burden on individuals and societies worldwide. Lifestyle changes, such as eating a healthy diet and getting more exercise, can delay or reduce the risk of developing diabetes in people ...

Researchers developed TetrapodTraits – a global database of animals with four feet – which can now be applied for better ecology, evolution and conservation research. Mario Moura of the Universidade Estadual de Campinas, Brazil, and Walter Jetz of Yale University, US, published this work on July 9th in the open-access journal PLOS Biology. Tetrapods, which include amphibians, reptiles, birds and mammals, are generally well-documented species, which makes them useful as models in global biodiversity studies. However, gaps in our knowledge about many of these species, data inconsistencies and shifting scientific names can lead to biased conclusions about biodiversity. To help ...

“In this study, we investigated the therapeutic effects and the underlying mechanisms of TAS-102 in combination with regorafenib against gastrointestinal cancers.” BUFFALO, NY- July 9, 2024 – A new research paper was published in Oncotarget's Volume 15 on July 2, 2024, entitled, “Regorafenib synergizes with TAS102 against multiple gastrointestinal cancers and overcomes cancer stemness, trifluridine-induced angiogenesis, ERK1/2 and STAT3 signaling regardless of KRAS or BRAF mutational status.” Single-agent TAS102 (trifluridine/tipiracil) and regorafenib ...

Researchers at University of California San Diego have found that the most common form of liver cancer — one with a high mortality rate — can be better targeted and treated using an innovative new stem cell-derived therapy, according to a recently published study in Cell Stem Cell. The treatment, not yet studied in patients, involves the lab engineering of natural killer (NK) cells — white blood cells that destroy tumor cells — to more effectively battle hepatocellular carcinoma (HCC), one of the most treatment-resistant types of solid tumor. Genetically modified NK-cell therapy doesn't require ...

A new study published today in Current Biology, "Oceanic Seabirds Chase Tropical Cyclones," reveals that the rare Desertas Petrels (Pterodroma deserta), a wide-ranging seabird in the North Atlantic, exhibit unique foraging behaviors during hurricane season. Contrary to other pelagic seabirds, these petrels do not avoid intense tropical cyclones but instead exploit the dynamic conditions for their benefit, providing new insights into the impact of cyclones on open ocean marine life. "Initial studies suggested that seabirds either circumnavigate cyclones or seek refuge in the calm eye of the storm. However, the Desertas Petrels we tracked did neither; instead, one-third of ...

During his recent yearlong sabbatical, Daniel Laughlin led a study that found trees can sustain life in temperatures higher or lower than where they are currently growing. While tree species appear to prefer distinct climatic conditions, the true nature of these preferences is obscured by species interactions and dispersal, which limit tree species’ ranges. “We were amazed. The result was crystal clear, and that doesn’t always happen in ecology,” says Laughlin, a professor in the University of Wyoming Department of Botany. “We found that tree species could grow and survive at one common moderate temperature, even though many ...

CHARLOTTE, N.C. – Advocate Health has been selected by the Centers for Medicare and Medicaid Services (CMS) to participate in the Guiding an Improved Dementia Experience (GUIDE) Model, aimed to support advanced dementia patients and their caregivers in bridging the gaps associated with inequalities in dementia care. Following years of neurocognitive disorders research pioneered by Advocate Health's academic core,  Wake Forest University School of Medicine,  patients across the health system’s footprint now will benefit from the GUIDE Model’s new standardized approach to care for patients with dementia and their caregivers.
