Precision instrument bolsters efforts to find elusive dark energy

Dark energy — a mysterious force pushing the universe apart at an ever-increasing rate — was discovered 26 years ago, and ever since, scientists have been searching for a new and exotic particle causing the expansion. Pushing the boundaries of this search, University of California, Berkeley physicists have now built the most precise experiment yet to look for minor deviations from the accepted theory of gravity that could be evidence for such a particle, which theorists have dubbed a chameleon or symmetron. The experiment, which combines an atom interferometer for precise gravity ...

New survey from NCCN finds cancer drug shortage management remains a moving target, impacting clinical trials

PLYMOUTH MEETING, PA [June 26, 2024] — The National Comprehensive Cancer Network® (NCCN®)—a nonprofit alliance of leading cancer centers—is publishing new results for its latest survey on cancer drug shortages in the United States. This follows data published one year ago, and six months ago, illustrating how up to 93% of centers surveyed were experiencing shortages of the crucial chemotherapy carboplatin at its peak. In June 2023, 70% of centers surveyed were also lacking adequate supply for cisplatin. In the latest survey, only 11% of surveyed centers reported a shortage of carboplatin and 7% for cisplatin; but new concerns have emerged. “Critical ...

Biting flies on dairy farms can spread bovine mastitis

Highlights: Bovine mastitis is a potentially fatal condition with myriad known causes, including bacteria. Biting flies may help cause mastitis, but the mechanisms are not well elucidated. Researchers characterized microbial diversity in biting flies and manure to look for connections. The flies carried relevant bacterial strains, also found in the manure, associated with mastitis. The research may point to new strategies for protecting cows from disease-causing pathogens.   Washington, D.C.—Bovine mastitis, which affects cows, leads to reduced milk production and can be fatal if left untreated.

Balancing act: Novel wearable sensors and AI transform balance assessment

Balance can be impacted by various factors, including diseases such as Parkinson’s disease, acute and chronic injuries to the nervous system, and the natural aging process. Accurately assessing balance in patients is important to identify and manage conditions that affect coordination and stability. Balance assessments also play a key role in preventing falls, understanding movement disorders, and designing appropriate therapeutic interventions across age groups and medical conditions. However, traditional methods used to assess balance often suffer from subjectivity, are not comprehensive enough and cannot be administered remotely. Moreover, these assessments rely on expensive, ...

Stars blinking code in Netflix’s “3 Body Problem” might be science fiction, but by deciphering neutron stars’ erratic flickers, a new study has revealed the twisted origin of these dead stars’ mysterious “heartbeats.” When neutron stars—ultra-dense remnants of massive stars that exploded in supernovae—were first discovered in 1967, astronomers thought their strange periodic pulses could be signals from an alien civilization. Although we now know these “heartbeats” ...

Some landfill ‘burps’ contain airborne PFAS, study finds

Many municipal landfills “burp” gas from decomposing organic matter rather than letting it build up. And burps from buried waste containing per- and polyfluoroalkyl substances (PFAS) can release these “forever chemicals” into the air, say researchers in ACS’ Environmental Science & Technology Letters. Their study reports unexpectedly high levels of airborne PFAS at three landfills and demonstrates that vented gases and liquid by-products called leachates could transport similar amounts of these contaminants to the environment. Some consumer products and commercial waste, such as children’s clothing, cosmetics and wastewater treatment sludge solids, contain ...

Small, adsorbent ‘fins’ collect humidity rather than swim through water

Clean, safe water is a limited resource and access to it depends on local bodies of water. But even dry regions have some water vapor in the air. To harvest small amounts of humidity, researchers in ACS Energy Letters have developed a compact device with absorbent-coated fins that first trap moisture and then generate potable water when heated. They say the prototype could help meet growing demands for water, especially in arid locations. Earth’s atmosphere holds trillions of liters of fresh water as vapor, but it’s challenging to collect this colorless, transparent and dilute gas. Previously, researchers developed systems that trap ...

Plankton researchers urge their colleagues to mix it up

Comprising the base of the food web, plankton are extremely important to marine ecosystems. However, there is still much to be discovered about these organisms, and that’s especially true for mixoplankton. Plankton are typically divided into two groups. Similar to plants, phytoplankton contain chlorophyll and derive energy from photosynthesis. Zooplankton, on the other hand, consume other organisms for their energy. However, there is also a third group, mixoplankton, that is a combination of the two. And, despite accounting for, at times, more than half of all plankton in the ocean, they remain ...

Towards non-toxic antifouling agents: A novel method for total synthesis of scabrolide F

Marine organisms produce many organic compounds with diverse chemical structures and biological activities. These natural marine products are regarded as potential starting points for the discovery and development of new drugs. Among these are norcembranolide diterpenes isolated from the soft corals of the genus Sinularia. These compounds exhibit diverse biological activities, and many of them have anti-cancer and anti-inflammatory properties. Consequently, many studies have investigated the properties of norcembranolide diterpenes and their synthesis methods. Given their potential in drug discovery, developing a synthetic ...
