A new study examines the symbiotic relationship between two types of bacteria and spittlebugs that helps the insect live on very low-nutrient food.
Wildfires can alter Arctic watersheds for 50 years
- ScienceDaily
- 20/5/28 22:11
Climate change has contributed to the increase in the number of wildfires in the Arctic and can dramatically shift stream chemistry. Researchers at the University of New Hampshire have found that some of the aftereffects, like decreased carbon and increased nitrogen, can last up to five decades and could have major implications on vital waterways like the Yenisei River and the Arctic Ocean
Using electrical stimulus to regulate genes

A team of researchers has succeeded in using an electric current to directly control gene expression for the first time. Their work provides the basis for medical implants that can be switched on and off using electronic devices outside the body.
New technology enables fast protein synthesis
- ScienceDaily
- 20/5/28 22:10
Chemists have developed a protocol to rapidly produce protein chains up to 164 amino acids long. The flow-based technology could speed up drug development and allow scientists to design novel protein variants incorporating amino acids that don't occur naturally in cells.
Gold mining with mercury poses health threats for miles downstream
- ScienceDaily
- 20/5/28 22:10
Small-scale gold mining in the Peruvian Amazon poses a health hazard not only to the miners and communities near where mercury is used to extract gold from ore, but also to downstream communities hundreds of kilometers away where people eat mercury-contaminated river fish as part of their diet. Downstream children under 12 with the highest levels of mercury in their bodies were found to have lost...
Global environmental changes leading to shorter, younger trees
- ScienceDaily
- 20/5/28 22:10
Ongoing environmental changes are transforming forests worldwide, resulting in shorter and younger trees. Researchers found that a range of factors, including rising temperatures and carbon dioxide levels, have caused a dramatic decrease in the age and stature of forests.
New 'whirling' state of matter discovered in an element of the periodic table
- ScienceDaily
- 20/5/28 22:10
The strongest permanent magnets today contain a mix of the elements neodymium and iron. However, neodymium on its own does not behave like any known magnet, confounding researchers for more than half a century. Physicists have now shown that neodymium behaves like a so-called 'self-induced spin glass,' meaning that it is composed of a rippled sea of many tiny whirling magnets circulating at...
In planet formation, it's location, location, location
- ScienceDaily
- 20/5/28 22:06
Astronomers are finding that planets have a tough time forming in the rough-and-tumble central region of the massive, crowded star cluster Westerlund 2. Located 20,000 light-years away, Westerlund 2 is a unique laboratory to study stellar evolutionary processes because it's relatively nearby, quite young, and contains a large stellar population.
CBD improves arthritis symptoms in dogs
- ScienceDaily
- 20/5/28 22:06
This study shows that in dogs diagnosed with arthritis, CBD treatment significantly improved quality of life as documented by both owner and veterinarian assessments.
Benefits of social networks to disaster response questioned
- ScienceDaily
- 20/5/28 22:05
Faced with a common peril, people delay making decisions that might save lives, fail to alert each other to danger and spread misinformation. Those may sound like behaviors associated with the current pandemic, but they actually surfaced in experiments on how social networks function in emergencies.
Breaking up is hard to do (especially for sex chromosomes)
- ScienceDaily
- 20/5/28 22:05
A team of scientists has discovered how the X and Y chromosomes find one another, break, and recombine during meiosis even though they have little in common.
Heart surgery stalled as COVID-19 spread
- ScienceDaily
- 20/5/28 22:05
Two recent journal articles explore how hospitals worldwide scaled back on heart surgeries as the pandemic hit, and how they can resume those operations in a world still plagued by the SARS-CoV-2 virus.
Antarctic ice sheets capable of retreating up to 50 meters per day
- ScienceDaily
- 20/5/28 22:05
The ice shelves surrounding the Antarctic coastline retreated at speeds of up to 50 meters per day at the end of the last Ice Age, far more rapid than the satellite-derived retreat rates observed today, new research has found.
Imaging reveals unexpected contractions in the human placenta
- ScienceDaily
- 20/5/28 22:05
High-resolution imaging of the human placenta provides new insights into blood circulation patterns that are crucial for fetal development, according to a new study. These findings improve our understanding of the functioning of this understudied organ, both in healthy pregnancies and in serious medical conditions such as pre-eclampsia.
Researchers identify mechanisms that make skin a protective barrier
- ScienceDaily
- 20/5/28 22:05
A research team has identified one of the mechanisms that establish the skin as a protective barrier, a breakthrough that is critical to understanding and treating common skin conditions including eczema and psoriasis, according to a new study.
Environmental groups moving beyond conservation
- ScienceDaily
- 20/5/28 22:05
Although non-governmental organizations (NGOs) have become powerful voices in world environmental politics, little is known of the global picture of this sector. A new study shows that environmental groups are increasingly focused on advocacy in climate change politics and environmental justice. How they do their work is largely determined by regional disparities in human and financial resources.
Changes in cropping methods, climate decoy pintail ducks into an ecological trap
- ScienceDaily
- 20/5/28 22:05
After a severe drought gripped the Prairie Pothole Region of the U.S. and Canada in the 1980s, populations of almost all dabbling duck species that breed there have recovered. But not northern pintails. Now, a new study suggests why -- they have been caught in an ecological trap.
