Invasive populations of tiger mosquitoes continuously expand the diversity of hosts in their blood-meal
2024-10-07
The invasive mosquito species, the tiger mosquito (Aedes albopictus), poses significant threats to human and animal health due to its ability to spread over large geographic areas and act as a vector for numerous pathogens. Understanding the ecological relationships this species establishes in different locations is crucial for assessing its worldwide dispersion success and its role in disease transmission. To uncover how invasiveness couples with the ability to adapt to various food sources László Zsolt Garamszegi from the ...
After injury, these comb jellies can fuse to become one
2024-10-07
Researchers reporting in the Cell Press journal Current Biology on October 7 have made the surprising discovery that one species of comb jelly (Mnemiopsis leidyi) can fuse, such that two individuals readily turn into one following an injury. Afterwards, they rapidly synchronize their muscle contractions and merge digestive tracts to share food.
“Our findings suggest that ctenophores may lack a system for allorecognition, which is the ability to distinguish between self and others,” says Kei Jokura (@Ctenophore18) of the University of Exeter, UK, and National Institutes of Natural Sciences in Okazaki, ...

An early blood test can predict survival in patients with metastatic prostate cancer, shows USC study
2024-10-07
A blood test, performed when metastatic prostate cancer is first diagnosed, can predict which patients are likely to respond to treatment and survive the longest. It can help providers decide which patients should receive standard treatment versus who might stand to benefit from riskier, more aggressive new drug trials. The research, part of a phase 3 clinical trial funded in part by the National Cancer Institute (NCI) of the National Institutes of Health, was just published in JAMA Network Open.
Before it spreads, prostate cancer can be cured with surgery or ...
Scientists discover that special immune cells stop metastatic cancer
2024-10-07
October 7, 2024—(BRONX, NY)—Metastatic disease—when cancer spreads from the primary tumor to other parts of the body—is the cause of most cancer deaths. While researchers understand how cancer cells escape the primary site to seed new tumors, it’s not well understood why some of these wayward cancer cells spawn new tumors— sometimes decades later—while others do not.
Now, a research team at the National Cancer Institute-designated Montefiore Einstein ...
Cancer biologists discover a new mechanism for an old drug
2024-10-07
Since the 1950s, a chemotherapy drug known as 5-fluorouracil has been used to treat many types of cancer, including blood cancers and cancers of the digestive tract.
Doctors have long believed that this drug works by damaging the building blocks of DNA. However, a new study from MIT has found that in cancers of the colon and other gastrointestinal cancers, it actually kills cells by interfering with RNA synthesis.
The findings could have a significant effect on how doctors treat many cancer patients. Usually, 5-fluorouracil is given in combination with chemotherapy drugs that damage ...
Food deserts, limited access to transportation linked to more complications among preschool children with SCD
2024-10-07
(WASHINGTON – October 7, 2024) - A new study finds that preschool-aged children with sickle cell disease (SCD) who live in food deserts and have limited access to transportation are at greater risk for acute complications and hospitalizations, despite receiving free evidence-based therapy and social support, according to results published today in Blood Advances.
“Despite the level of care received by the families and patients within our clinic, we still have a gap in terms of being able to address the barriers ...
Space oddity: Most distant rotating disc galaxy found
2024-10-07
Researchers have discovered the most distant Milky-Way-like galaxy yet observed. Dubbed REBELS-25, this disc galaxy seems as orderly as present-day galaxies, but we see it as it was when the Universe was only 700 million years old. This is surprising since, according to our current understanding of galaxy formation, such early galaxies are expected to appear more chaotic. The rotation and structure of REBELS-25 were revealed using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European ...
How a common economic theory could help save endangered frogs
2024-10-07
A common theory that guides financial investment strategies may be a handy tool to protect an endangered Puerto Rican frog. A new study uses modern portfolio theory to identify future “investments” in natural resource management that may help managers decide which actions to take to protect coquí llanero populations in Puerto Rico.
The 17 species of coquí frogs, and their signature high-pitched chirp, are considered unofficial mascots of Puerto Rico. The entire population of coquí llanero frogs, the smallest and possibly most endangered of the island’s coquís, ...
Stopping off-the-wall behavior in fusion reactors
2024-10-07
Fusion researchers are increasingly turning to the element tungsten when looking for an ideal material for components that will directly face the plasma inside fusion reactors known as tokamaks and stellarators. But under the intense heat of fusion plasma, tungsten atoms from the wall can sputter off and enter the plasma. Too much tungsten in the plasma would substantially cool it, which would make sustaining fusion reactions very challenging. Now, researchers at the U.S. Department of Energy’s Princeton Plasma Physics Laboratory (PPPL) have experimental results suggesting that sprinkling ...

NCSA building stronger connections among observatories, astronomers
2024-10-07
With hundreds of observatories scattered throughout the world, there has never been a better time for astronomers to observe the infinite universe that lies beyond Earth. At any moment in time, a telescope pointed at the night sky can observe new transient phenomena, such as supernovae that brighten rapidly and then fade away over days to months, releasing massive amounts of energy in the process. These events are rare in any single galaxy and each gives researchers more insight into the dynamic time-domain sky.
But what if these observatories could work even closer together to view these important astronomical events?

Bias found when drug manufacturers fund clinical trials
2024-10-07
COLUMBUS, Ohio – Psychiatric drugs are reported to be about 50% more effective in clinical trials funded by the drug’s manufacturer than when trials of the same drug are sponsored by other groups, new research shows.
While many studies have found more favorable results for drugs in clinical trials funded by their manufacturers, these studies normally just compare a set of manufacturer-funded studies with a set of studies funded in other ways, said Tamar Oostrom, assistant professor of economics at The Ohio State University, who conducted this new research.

Gut hormones could hold the key to fighting fatty liver disease
2024-10-07
The accumulation of fats in the liver is driven by high-fat diets and obesity, and is becoming an increasingly prevalent global health concern. Characterized by excessive fat accumulation in the liver, this condition poses significant risks for various metabolic disorders. While much of the existing research has focused on fat metabolism within the liver itself, emerging findings emphasize the critical role of the gut in this complex process. Proglucagon-derived peptides (PGDPs), including glucagon, GLP-1, and GLP-2, are known to be the key hormones that regulate lipid metabolism in the liver. Derived from the same precursor—proglucagon, previous studies ...
