| Surveys with repetitive questions yield bad data, study finds Posted: 28 Jan 2022 12:35 PM PST Surveys that ask too many of the same type of question tire respondents and return unreliable data, according to a new study. The study found that people tire from questions that vary only slightly and tend to give similar answers to all questions as the survey progresses. Marketers, policymakers, and researchers who rely on long surveys to predict consumer or voter behavior will have more accurate data if they craft surveys designed to elicit reliable, original answers, the researchers suggest. |

The trial also found that the safety of this experimental treatment may vary depending on whether a person naturally generates SARS-CoV-2-neutralizing antibodies before receiving it. |
| Peruvian gold rush turns pristine rainforests into heavily polluted mercury sinks Posted: 28 Jan 2022 05:57 AM PST Illegal gold mining in the Peruvian Amazon is causing exceptionally high levels of atmospheric mercury pollution in a nearby patch of pristine rainforest. One stand of old-growth pristine forest had the highest levels of mercury ever recorded, rivaling industrial areas where mercury is mined. Birds from this area have up to twelve times more mercury in their system than birds from less polluted areas, a level of poisoning that should harm their reproduction. |

| Infant deaths from RSV are much higher than previously known Posted: 27 Jan 2022 02:26 PM PST A new study has found that the true burden of RSV infant mortality is substantially higher than what was previously believed. The study used systematic surveillance to measure the presence of RSV among infants who died in medical facilities or in the community and found that the virus was present in 7 to 9 percent of infants under 6 months old and was primarily concentrated in infants under 3 months old. Two-thirds of these deaths occurred in the community -- i.e., among infants who never received medical care in a hospital and were overlooked in previous facility-based surveillance. |
| Crowding, climate change, and the case for distancing among trees Posted: 27 Jan 2022 02:26 PM PST In the age of large-scale fires, forest-wide beetle invasions, and frequent drought, maintaining 'ideal' historical conditions is becoming increasingly unrealistic. Novel conditions require different strategies; lower crowding for trees can increase chances of survival after fire. Results from two long-term studies show that chances for long-term tree survival increased when trees had more space, by reducing competition and helping trees recover from fire more quickly. |
| Gene regulation: How long do proteins bind? Posted: 27 Jan 2022 11:15 AM PST Researchers show how a DNA-binding protein can search the entire genome for its target sequence without getting held up on the way. The result contradicts our current understanding of gene regulation - the genetic code affects how often the proteins bind, but not for how long. |
| Cosmic physics mimicked on table-top as graphene enables Schwinger effect Posted: 27 Jan 2022 11:15 AM PST Researchers have succeeded in observing the so-called Schwinger effect, an elusive process that normally occurs only in cosmic events. By applying high currents through specially designed graphene-based devices, the team succeeded in producing particle-antiparticle pairs from a vacuum. |
| A mathematical secret of lizard camouflage Posted: 27 Jan 2022 08:43 AM PST The shape-shifting clouds of starling birds, the organization of neural networks or the structure of an anthill: nature is full of complex systems whose behaviors can be modeled using mathematical tools. The same is true for the labyrinthine patterns formed by the green or black scales of the ocellated lizard. A multidisciplinary team explains, thanks to a very simple mathematical equation, the complexity of the system that generates these patterns. This discovery contributes to a better understanding of the evolution of skin color patterns: the process allows for many different locations of green and black scales but always leads to an optimal pattern for the animal survival. |
