Think fast — or not: FSU research describes mathematics behind decision making
2024-08-13
New research from a Florida State University professor and colleagues explains the mathematics behind how initial predispositions and additional information affect decision making.
The research team’s findings show that when decision makers quickly come to a conclusion, the decision is more influenced by their initial bias, or a tendency to err on the side of one of the choices presented. If decision makers wait to gather more information, the slower decision will be less biased. The work was published today in Physical Review E.
“The basic result might ...
Largest study of its kind finds common lab tests aren’t reliable for diagnosing Long COVID
2024-08-13
A new study found that most routine laboratory tests are not reliable for diagnosing Long COVID, also known as Post-Acute Sequelae of SARS-CoV-2 infection (PASC).
The study, published today in Annals of Internal Medicine, found no reliable biomarker among 25 routine clinical laboratory values for prior infection, PASC or specific types of PASC clusters. This suggests none of these routine labs can serve as a clinically useful biomarker of PASC.
"Our study shows patients can have severe Long COVID with normal lab results. This ...
Engineers make tunable, shape-changing metamaterial inspired by vintage toys
2024-08-12
Common push puppet toys in the shapes of animals and popular figures can move or collapse with the push of a button at the bottom of the toys’ base. Now, a team of UCLA engineers has created a new class of tunable dynamic material that mimics the inner workings of push puppets, with applications for soft robotics, reconfigurable architectures and space engineering.
Inside a push puppet, there are connecting cords that, when pulled taught, will make the toy stand stiff. But by loosening these cords, the “limbs” of the toy will go limp. Using the same cord tension-based principle that controls a puppet, researchers have developed a new type of metamaterial, a material ...

Study reveals oleoyl-ACP-hydrolase underpins lethal respiratory viral disease
2024-08-12
Respiratory infections can be severe, even deadly, in some individuals, but not in others. Scientists at St. Jude Children’s Research Hospital, the Peter Doherty Institute for Infection and Immunity and other collaborators have gained new understanding of why this is the case by uncovering an early molecular driver that underpins fatal disease. Oleoyl-ACP-hydrolase (OLAH) is an enzyme involved in fatty acid metabolism. A study, published today in Cell, shows that OLAH drives severe disease outcomes.
The important role of OLAH in immune response has gone unrecognized for several reasons, including a lack of noticeable expression in healthy ...

Presence of liquid water most probable explanation for data collected by mars lander
2024-08-12
Data about Mars’ planetary crust gathered from the Mars InSight lander are best explained by the conclusion that the crust has stores of liquid water.
Analysis led by Vashan Wright, a geophysicist at UC San Diego’s Scripps Institution of Oceanography, provides the best evidence to date that the planet still has liquid water in addition to that frozen at its poles. If that conclusion is true, it sets the stage for new research considering the planet’s habitability and continuing a search for life that exists on a place other than Earth. The potential presence of liquid water on Mars has tantalized scientists for decades. Water is essential for a habitable planet.
“Understanding ...
Scientists find oceans of water on Mars. It's just too deep to tap.
2024-08-12
Using seismic activity to probe the interior of Mars, geophysicists have found evidence for a large underground reservoir of liquid water — enough to fill oceans on the planet's surface.
The data from NASA's Insight lander allowed the scientists to estimate that the amount of groundwater could cover the entire planet to a depth of between 1 and 2 kilometers, or about a mile.
While that’s good news for those tracking the fate of water on the planet after its oceans disappeared more than 3 billion years ago, the reservoir won't be of much use to anyone trying to tap into it to supply a future Mars colony. It's ...
UMass Amherst researchers ID body’s ‘quality control’ regulator for protein folding
2024-08-12
AMHERST, Mass. – Anyone who’s tried to neatly gather a fitted sheet can tell you: folding is hard. Get it wrong with your laundry and the result can be a crumpled, wrinkled mess of fabric, but when folding fails among the approximately 7,000 proteins with an origami-like complexity that regulate essential cellular functions, the result can lead to one of a multitude of serious diseases ranging from emphysema and cystic fibrosis to Alzheimer’s disease. Fortunately, our bodies have a quality-control system ...
Forest restoration can boost people, nature and climate simultaneously
2024-08-12
Forest restoration can benefit humans, boost biodiversity and help tackle climate change simultaneously, new research suggests.
Restoring forests is often seen in terms of “trade-offs” – meaning it often focuses on a specific goal such as capturing carbon, nurturing nature or supporting human livelihoods.
The new study, by the universities of Exeter and Oxford, found that restoration plans aimed at a single goal tend not to deliver the others.
However, “integrated” plans would deliver over 80% of the benefits in all three areas at once.
It also found that ...
Pre-surgical antibody treatment might prevent heart transplant rejection
2024-08-12
A new study from scientists at Cincinnati Children’s suggests there may be a way to further protect transplanted hearts from rejection by preparing the donor organ and the recipient with an anti-inflammatory antibody treatment before surgery occurs.
The findings, published online in PNAS, focus on blocking an innate immune response that normally occurs in response to microbial infections. The same response has been shown to drive dangerous inflammation in transplanted hearts.
In the new study – in mice -- transplanted hearts functioned for longer periods when the organ recipients ...
