In Brazil, many smaller dams disrupt fish more than large hydropower projects
- ScienceDaily
- 21/1/27 23:18
A new article quantifies the tradeoffs between hydroelectric generation capacity and the impacts on river connectivity for thousands of current and projected future dams across Brazil. The findings confirm that small hydropower plants are far more responsible for river fragmentation than their larger counterparts due to their prevalence and distribution.

The right combination of surfactant, water and processing can maximize the quality of 2D hexagonal boron nitride for such products as antibacterial films.
New report charts path toward superior earthquake recovery
- ScienceDaily
- 21/1/27 21:25
A committee of experts has urged officials at all levels of government to support research and policies that could help get the buildings and services society depends on up and running quickly after an earthquake. In a report delivered to Congress, the committee outlines seven recommendations that, if acted upon, may greatly improve the resilience of communities across the nation.
A metalens for virtual and augmented reality
- ScienceDaily
- 21/1/27 21:25
Researchers have developed a two-millimeter achromatic metalenses that can focus RGB (red, blue, green) colors without aberrations and developed a miniaturized display for virtual and augmented reality applications.
Purported phosphine on Venus more likely to be ordinary sulfur dioxide
- ScienceDaily
- 21/1/27 20:01
Astronomers revisited and comprehensively reinterpreted the radio telescope observations underlying a widely reported 2019 claim that phosphine gas was present in the atmosphere of Venus. In a paper accepted to the Astrophysical Journal, they report that sulfur dioxide, a common gas in the atmosphere of Venus, is likely what was detected instead of phosphine.
Up-trending farming and landscape disruptions threaten Paris climate agreement goals
- ScienceDaily
- 21/1/27 20:01
Earth system science researchers conducted an analysis of greenhouse gas emissions from agriculture and land use since 1961, finding some opportunities for mitigation as well as areas where curtailment will require sacrifices.
First ever 'pioneer' factor found in plants enables cells to change their fate
- ScienceDaily
- 21/1/27 20:01
To start the process of unpacking tightly bundled genetic material, plants depend on the LEAFY pioneer protein, according biologists.
T cells can mount attacks against many SARS-CoV-2 targets -- even on new virus variant
- ScienceDaily
- 21/1/27 20:01
A new study suggests that T cells try to fight SARS-CoV-2 by targeting a broad range of sites on the virus -- beyond the key sites on the virus's spike protein. By attacking the virus from many angles, the body has the tools to potentially recognize different SARS-CoV-2 variants.
How breast cancer cells hide from immune attack
- ScienceDaily
- 21/1/27 20:01
Researchers at the Indiana University Melvin and Bren Simon Comprehensive Cancer Center have identified how breast cancer cells hide from immune cells to stay alive. The discovery could lead to better immunotherapy treatment for patients.

Pain patients who take opioids can't get in the door at over half of primary care clinics
- ScienceDaily
- 21/1/27 20:01
People who take opioid medications for chronic pain may have a hard time finding a new primary care clinic that will take them as a patient if they need one, according to a new 'secret shopper' study of hundreds of clinics across the country. Stigma against long-term users of prescription opioids, likely related to the prospect of taking on a patient who might have an opioid use disorder or...
A NEAT reduction of complex neuronal models accelerates brain research
- ScienceDaily
- 21/1/27 20:00
Unlike their simple counterparts in artificial intelligence (AI) applications, neurons in the brain use dendrites - their intricate tree-like branches - to find relevant chunks of information. Now, neuroscientists have discovered a new computational method to make complex dendrite models much simpler. These faithful reductions may lead AI applications to process information much like the brain...
A newly discovered circuit helps fish to prioritize
- ScienceDaily
- 21/1/27 20:00
Being constantly flooded by a mass of stimuli, it is impossible for us to react to all of them. The same holds true for a little fish. Which stimuli should it pay attention to and which not? Scientists have now deciphered the neuronal circuit that zebrafish use to prioritize visual stimuli. Surrounded by predators, a fish can thus choose its escape route from this predicament.
