Warning witnesses of the possibility of misinformation helps protect their memory accuracy
Warning about the threat of misinformation -- before or after an event -- significantly reduces the negative impact of misinformation on memory, according to research at Tufts University. The findings could have important implications for improving the accuracy of everyday memory and eyewitness testimony.

Dodder uses the flowering signal of its host plant to flower
Researchers from the Chinese Academy of Sciences and the Max Planck Institute for Chemical Ecology have investigated how the parasitic dodder Cuscuta australis controls flower formation. They showed that the parasite eavesdrops on the flowering signals of its host plants in order to activate its own flowering machinery. By synchronizing flowering with its host plant, the parasite makes sure that it can grow on its host long enough to produce the optimal amount of seeds.

Warmer, acidifying ocean brings extinction for reef-building corals, renewal for relatives
A new study, published Aug. 31 in the journal Nature Ecology and Evolution, finds that reef-building corals emerged only when ocean conditions supported the construction of these creatures' stony skeletons, whereas diverse softer corals and sea anemones flourished at other times. Without a significant change to anthropogenic carbon emissions, the new findings present stark implications for the present and future of hard-bodied corals while suggesting a silver lining for the diversity of some of their softer-bodied relatives.

Natural disasters must be unusual or deadly to prompt local climate policy change
Natural disasters alone are not enough to motivate local communities to engage in climate change mitigation or adaptation, a new study from Oregon State University found. Rather, policy change in response to extreme weather events appears to depend on a combination of factors, including fatalities, sustained media coverage, the unusualness of the event and the political makeup of the community.

Researchers dramatically downsize technology for fingerprinting drugs and other chemicals
As new infectious diseases emerge and spread, one of the best shots against novel pathogens is finding new medicines or vaccines. But before drugs can be used as potential cures, they have to be painstakingly screened for composition, safety and purity, among other things. Thus, there is an increasing demand for technologies that can characterize chemical compounds quickly and in real time.

Only the nose knows: New international network explores how odors lead to actions
The University of Colorado Boulder will lead a groundbreaking new international research network dubbed Odor2Action starting this fall. The work is aimed at understanding how animals use information from odors in their environment to guide behavior, with far-ranging implications for our understanding of the human brain.

Fidelity of El Niño simulation matters for predicting future climate
A new study led by University of Hawai'i at Mānoa researchers, published in the journal Nature Communications this week, revealed that correctly simulating ocean current variations hundreds of feet below the ocean surface - the so-called Pacific Equatorial Undercurrent - during El Niño events is key in reducing the uncertainty of predictions of future warming in the eastern tropical Pacific.

Evidence of hibernation-like state in Antarctic animal
Among the many winter survival strategies in the animal world, hibernation is one of the most common. According to new research, this type of adaptation has a long history. In a paper published in the journal Communications Biology, scientists at Harvard University and the University of Washington report evidence of a hibernation-like state in an animal that lived in Antarctica during the Early Triassic, some 250 million years ago.

Ocean acidification causing coral 'osteoporosis' on iconic reefs
Scientists have long suspected that ocean acidification is affecting corals' ability to build their skeletons, but it has been challenging to isolate its effect from that of simultaneous warming ocean temperatures, which also influence coral growth. New research from the Woods Hole Oceanographic Institution (WHOI) reveals the distinct impact that ocean acidification is having on coral growth on some of the world's iconic reefs.

Playfulness can be trained - here's why you should do it
Simple exercises can help to make people more playful and consequently feel more satisfied with their lives. This has been revealed in a new study by psychologists from Martin Luther University Halle-Wittenberg (MLU) in the journal "Applied Psychology: Health and Well-Being". The researchers had participants in an experiment perform a week of exercises to boost their playfulness. They found that the trait can be stimulated and trained - and that this improves a person's mood.

Fossil evidence of 'hibernation-like' state in 250-million-year-old Antarctic animal
University of Washington scientists report evidence of a hibernation-like state in Lystrosaurus, an animal that lived in Antarctica during the Early Triassic, some 250 million years ago. The fossils are the oldest evidence of a hibernation-like state in a vertebrate, and indicate that torpor -- a general term for hibernation and similar states in which animals temporarily lower their metabolic rate to get through a tough season -- arose in vertebrates even before mammals and dinosaurs evolved.

A new method for making a key component of plastics
Scientists have discovered a previously unknown way that some bacteria produce the chemical ethylene - a finding that could lead to new ways to produce plastics without using fossil fuels. The study, published today (Aug. 27, 2020) in the journal Science, showed that the bacteria created ethylene gas as a byproduct of metabolizing sulfur, which they need to survive.
