- Glaciers in northern Antarctic Peninsula melting faster than ever despite inc...
Increased snowfall will not prevent the continued melting of glaciers in the northern Antarctic Peninsula, according to new research. Scientists have discovered that small glaciers that end on land around the Antarctic Peninsula are highly vulnerable to slight changes in air temperature and may be at risk of disappearing within 200 years.
- How an ancient vertebrate uses familiar tools to build a strange-looking head
show that the sea lamprey Petromyzon marinus, a survivor of ancient jawless vertebrates, exhibits a pattern of gene expression that is reminiscent of its jawed cousins, who evolved much, much later.
- Study sheds new light on why batteries go bad
A comprehensive look at how tiny particles in a lithium ion battery electrode behave shows that rapid-charging the battery and using it to do high-power, rapidly draining work may not be as damaging as researchers had thought -- and that the benefits of slow draining and charging may have been overestimated. The results challenge the prevailing view that 'supercharging' batteries is always harder on battery electrodes than charging at slower rates.
- Rules of thumb for climate change turned upside down: Wet and dry regions rec...
With a new analysis of land regions, climate researchers are challenging the general climate change paradigm that dry regions are getting drier and wet regions are getting wetter. In some regions they are encountering divergent trends.
- Three's a charm: Detectors reveal entangled photon triplets
Researchers have directly entangled three photons in the most technologically useful state for the first time, thanks in part to superfast, super-efficient single-photon detectors.
- genetic analysis on a species of African midge
Scientists have completed the genetic analysis on a species of African midge, which can survive a wide array of extreme conditions including large variations in temperature, extreme drought and even airless vacuums such as space. The team successfully deciphered the genetic mechanism that makes the midge invulnerable to these harsh conditions.
- Zebrafish Model of a Learning and Memory Disorder Shows Better Way to Target ...
Using a zebrafish model of a human genetic disease called neurofibromatosis, researchers have found that the learning and memory components of the disorder are distinct features that will likely need different treatment approaches.
- Boosting armor for nuclear-waste eating microbes
A microbe developed to clean up nuclear waste has just been improved. In earlier research, Gemma Reguera, A microbiologist identified that Geobacter bacteria's tiny conductive hair-like appendages, or pili, did the yeoman's share of remediation. By increasing the strength of the pili nanowires, she improved their ability to clean up uranium and other toxic wastes.
- Imaging fuel injectors with neutrons
Researchers are using neutrons to study the formation of these damage-causing bubbles in fuel injectors.
- How evolutionary principles could help save our world
The age of the Anthropocene -- the scientific name given to our current geologic age -- is dominated by human impacts on our environment. A warming climate. Increased resistance of pathogens and pests. A swelling population. Coping with these modern global challenges requires application of what one might call a more-ancient principle: evolution.
