Novel imaging platform allows researchers to study placental development in pregnant mice
2024-03-21
DURHAM, N.C. -- Physicians and biomedical engineers at Duke University have developed a method to visualize the growth of a placenta throughout a mouse’s pregnancy. By coupling an implantable window with ultrafast imaging tools, the approach provides the first opportunity to track placental development to better understand how the organ functions during pregnancy.
This new perspective gives researchers a precise way to examine how lifestyle factors like alcohol consumption and health complications like inflammation can affect the placenta and potentially lead to adverse pregnancy outcomes.
The research appears March 20 as the cover ...

Illinois study: Systematic review of agricultural injuries can help inform safety measures
2024-03-21
URBANA, Ill. – Agricultural occupations are hazardous with one of the highest rates of workplace injuries and fatalities in the U.S. The manual and often strenuous nature of the work, combined with the use of machinery and exposure to environmental hazards create a challenging work environment. Understanding the nature and causes of injuries can help improve safety guidelines and policy measures. However, obtaining a comprehensive overview of injuries is hindered by the absence of a central reporting system. Two ...
New vaccine against a highly fatal tropical disease – and potential bioterror weapon – demonstrates efficacy in animal studies
2024-03-21
In a mouse study, UCLA researchers tested a vaccine against the bacterium that causes melioidosis and found it was highly protective against the disease, which is endemic in many tropical areas, causing approximately 165,000 cases with 89,000 fatalities around the world each year.
The bacterium, called Burkholderia pseudomallei, is spread through contact with contaminated soil and water through inhalation, ingestion or broken skin. It is so dangerous that it is categorized as a Tier 1 Select Agent of bioterrorism, and it can cause ...

A new path to drug diversity
2024-03-21
Many important medicines, such as antibiotics and anticancer drugs, are derived from natural products from Bacteria. The enzyme complexes that produce these active ingredients have a modular design that makes them ideal tools for synthetic biology. By exploring protein evolution, a team led by Helge Bode from the Max Planck Institute for Terrestrial Microbiology in Marburg, Germany, has found new "fusion sites" that enable faster and more targeted drug development.
Industry often follows the assembly line principle: components are systematically assembled into complex products, with different production lines yielding different products. However, not humans are the ...
Satellite data assimilation improves forecasts of severe weather
2024-03-21
UNIVERSITY PARK, Pa. — In 2020, a line of severe thunderstorms unleashed powerful winds that caused billions in damages across the Midwest United States. A technique developed by Penn State scientists that incorporates satellite data could improve forecasts — including where the most powerful winds will occur — for similar severe weather events.
The researchers reported in the journal Geophysical Research Letters that adding microwave data collected by low-Earth-orbiting satellites to existing computer weather forecast models produced more accurate forecasts of surface gusts in a case study of the 2020 Midwest ...

Novel method to measure root depth may lead to more resilient crops
2024-03-21
UNIVERSITY PARK, Pa. — As climate change worsens global drought conditions, hindering crop production, the search for ways to capture and store atmospheric carbon causing the phenomenon has intensified. Penn State researchers have developed a new high-tech tool that could spur changes in how crops withstand drought, acquire nitrogen and store carbon deeper in soil.
In findings published in the January issue of Crop Science, they describe a process in which the depth of plant roots can be accurately estimated by scanning leaves with ...
Scientists develop catalyst designed to make ammonia production more sustainable
2024-03-21
Ammonia is one of the most widely produced chemicals in the world, and is used in a great many manufacturing and service industries. The conventional production technology is the Haber-Bosch process, which combines nitrogen gas (N2) and hydrogen gas (H2) in a reactor in the presence of a catalyst. This process requires high levels of temperature and pressure, resulting in substantial power consumption. Indeed, ammonia production is estimated to consume 1%-2% of the world’s electricity and to account for about 3% of global carbon emissions.
In pursuit of more sustainable alternatives, researchers affiliated with the Center for Development of Functional Materials (CDMF) ...
Forest, stream habitats keep energy exchanges in balance, global team finds
2024-03-21
UNIVERSITY PARK, Pa. — Forests and streams are separate but linked ecosystems, existing side by side, with energy and nutrients crossing their porous borders and flowing back and forth between them. For example, leaves fall from trees, enter streams, decay and feed aquatic insects. Those insects emerge from the waters and are eaten by birds and bats. An international team led by Penn State researchers has now found that these ecosystems appear to keep the energy exchanges in balance — a finding that the scientists called surprising.

Product that kills agricultural pests also deadly to native Pacific Northwest snail
2024-03-21
CORVALLIS, Ore. – A product used to control pest slugs on farms in multiple countries is deadly to least one type of native woodland snail endemic to the Pacific Northwest, according to scientists who say more study is needed before the product gains approval in the United States.
Dee Denver of the Oregon State University College of Science led a 10-week laboratory project that showed the effect of a biotool marketed as Nemaslug on the Pacific sideband snail. The study was published today in PLOS One.
Nemaslug is based on the organism Phasmarhabditis hermaphrodita, a species of tiny, parasitic worm known as a nematode.

Two keys needed to crack three locks for better engineered blood vessels
2024-03-21
UNIVERSITY PARK, Pa. — Blood vessels engineered from stem cells could help solve several research and clinical problems, from potentially providing a more comprehensive platform to screen if drug candidates can cross from the blood stream into the brain to developing lab-grown vascular tissue to support heart transplants, according to Penn State researchers. Led by Xiaojun “Lance” Lian, associate professor of biomedical engineering and of biology, the team discovered the specific molecular signals that can efficiently mature nascent stem cells into the endothelial cells that comprise the vessels and regulate exchanges to and ...

Improving & maintaining heart health after pregnancy may reduce the risk of future CVD
2024-03-21
Research Highlights:
An analysis of health records for almost 110,000 women in the U.K. found that women with poor cardiovascular health after pregnancy or who experienced adverse pregnancy outcomes, including high blood pressure, gestational diabetes and/or pre-term birth, had a significantly higher long-term risk of developing cardiovascular disease.
Among women with adverse pregnancy outcomes, those who maintained better cardiovascular health after pregnancy had cardiovascular disease risk similar to women who had no history of pregnancy complications.

New generation estrogen receptor-targeted agents in breast cancer
2024-03-21
https://www.scienceopen.com/hosted-document?doi=10.15212/AMM-2024-0006
Announcing a new publication for Acta Materia Medica journal. Endocrine therapy that blocks estrogen receptor signaling has been effective for decades as a primary treatment choice for breast cancer patients expressing the estrogen receptor. However, the issue of drug resistance poses a significant clinical challenge. It is therefore critically important to create new therapeutic agents that can suppress ERα activity, particularly in cases of ESR1 mutations. This review article highlights recent efforts in drug development of next ...
A new way to quantify climate change impacts: “Outdoor days”
2024-03-21
For most people, reading about the difference between a global average temperature rise of 1.5 C versus 2 C doesn’t conjure up a clear image of how their daily lives will actually be affected. So, researchers at MIT have come up with a different way of measuring and describing what global climate change patterns, in specific regions around the world, will mean for people’s daily activities and their quality of life.
The new measure, called “outdoor days,” describes the number of days per year that outdoor temperatures are neither too ...
