Even a small change may cause long-term consequences. For amyloid beta peptides, a major hallmark of Alzheimer's disease, a common chemical modification at a particular location on the molecule has a butterfly effect that leads to protein misfolding, aggregation and cellular toxicity.
But it's a dry heat: Climate change and the aridification of North America
- ScienceDaily
- 20/5/19 22:58
Discussions of drought often center on the lack of precipitation. But among climate scientists, the focus is shifting to include the growing role that warming temperatures are playing as potent drivers of greater aridity and drought intensification.

A new study finds that our mental health and mortality have a strong correlation with the amount of autonomy we have at our job, our workload and job demands, and our cognitive ability to deal with those demands.
Fishing rod 'selfie stick' and scientific sleuthing turn up clues to extinct sea reptile

A paleontologist visiting the Natural History Museum in London desperately wanted a good look at the skeleton of an extinct aquatic reptile, but its glass case was too far up the wall. So he attached his digital camera to a fishing rod and -- with several clicks -- snagged a big one, scientifically speaking.
Global CO2 emissions to drop 4-7% in 2020, but will it matter?
Global CO2 emissions from fossil fuels are set to drop by up to seven percent in 2020 because of the coronavirus pandemic, but even this dramatic decline—the sharpest since WWII—would barely dent longterm global warming, researchers reported Tuesday.
UAE to launch first Arab probe to Mars
After sending its first astronaut to space last year, the United Arab Emirates is to launch a probe to Mars in July, state news agency WAM announced Tuesday.
Flooding hits parts of Midwest, with evacuations in Michigan
People living along two mid-Michigan lakes and parts of a river were evacuated Tuesday following several days of heavy rain that produced flooding and put pressure on dams in the area.
Fishing rod 'selfie stick' and scientific sleuthing turn up clues to extinct sea reptile
A Russian paleontologist visiting the Natural History Museum in London desperately wanted a good look at the skeleton of an extinct aquatic reptile, but its glass case was too far up the wall. So he attached his digital camera to a fishing rod and—with several clicks—snagged a big one, scientifically speaking.
Scientists use light to accelerate supercurrents, access forbidden light, quantum world
Scientists are using light waves to accelerate supercurrents and access the unique properties of the quantum world, including forbidden light emissions that one day could be applied to high-speed, quantum computers, communications and other technologies.
Over a 15-year period, a small percentage of industrial facilities emit the majority of toxic pollution year after year
Call them "super polluters"—the handful of industrial facilities that emit unusually high levels of toxic chemical pollution year after year. There are only a few of them, but together they account for the majority of annual industrial pollution.

Study suggests aggressive carbon taxation could help US meet targets in Paris agreement
Nearly all the countries of the world ratified the Paris Agreement in 2016. The accord aims to limit the increase of the world's temperature to less than 2 degrees Celsius above pre-industrial temperatures. To do this, global greenhouse gas emissions would have to decrease roughly 25% below 2010 levels by 2030 and reach almost zero by 2070. As one of the largest emitters of greenhouse gases, the...

Field courses boost student success, support STEM diversity efforts, study reveals
The challenge of diversifying STEM fields may get a boost from the results of a new study that show field courses help build self-confidence among students—especially those from underrepresented groups.
NASA examines tropical storm Arthur's rainfall as it transitions
When the Global Precipitation Measurement mission or GPM core satellite passed over the western North Atlantic Ocean, it captured rainfall data on Tropical Storm Arthur as the storm was transitioning into an extra-tropical storm.
NASA-NOAA satellite sees Amphan's eye obscured
Early on May 18, 2020, Tropical Cyclone Amphan was a Category 5 storm in the Northern Indian Ocean. On May 19, satellite data from NASA-NOAA's Suomi NPP satellite revealed that the storm has weakened and the eye was covered by high clouds.
Ribs evolved for movement first, then co-opted for breathing
When early tetrapods transitioned from water to land the way they breathed air underwent an evolutionary revolution. Fish use muscles in their head to pump water over their gills. The first land animals utilized a similar technique—modern frogs still use their head and throat to force air into their lungs. Then another major transformation in vertebrate evolution took place that shifted...
What if we could design powerful drugs without unwanted side effects?
Psychedelics such as LSD and magic mushrooms have proven highly effective in treating depression and post-traumatic stress disorders, but medical use of these drugs is limited by the hallucinations they cause.
