Giving metal to microbes could reduce greenhouse gas
Like you and me, microbes need some metals in their diet to stay healthy. The metals help the microbes fully "digest" food. After a good meal, the microbes that gain energy by chemically reducing nitrate release a harmless byproduct: nitrogen, the gas that makes up 78% of Earth's atmosphere.
Deadly heatwaves threaten economies too
More frequent and intense heatwaves are the most deadly form of extreme weather made worse by global warming, with death tolls sometimes in the thousands, but they can also have devastating economic impacts too, experts say.

The signals that make cells self-destruct
Most human hearts look nearly identical—muscle cells in the same places, blood vessel structures in the same orientations. Organs such as hearts or stomachs look alike and function the same across individual organisms in a species because cells follow rigorous processes during development that get them precisely where they need to go.

Diffuse optics for medical diagnostics: Progress toward standardization
Among the various optics-based tools used in diagnostics, diffuse optics (DO) is rapidly emerging as one of the most attractive technologies. The technique is based on analyzing how light is absorbed and scattered by biological tissues, which relates to the tissue chemical composition and structure. One of the key advantages of DO is that it is non-invasive (it uses low-power near-infrared light)....

Corals and mangroves often grow near each other in tropical coastal environments, but finding...
Trade the chair for fresh air: Sitting time and cardio health
- ScienceDaily
- 22/6/15 21:27
New research is adding further weight to the argument that prolonged sitting may be hazardous to your health. An international study surveying more than 100,000 individuals in 21 countries found that people who sat for six to eight hours a day had a 12-13 per cent increased risk for early death and heart disease, while those who sat for more than eight hours daily increased that to a sobering 20...
Quantum electrodynamics tested 100 times more accurately than ever
Using a newly developed technique, scientists at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg have measured the very small difference in the magnetic properties of two isotopes of highly charged neon in an ion trap with previously inaccessible accuracy. Comparison with equally extremely precise theoretical calculations of this difference allows a record-level test of quantum...

To capture racism’s impact on health, one epidemiologist suggests going beyond conventional methods
The COVID-19 pandemic has exposed many vulnerabilities in health care, including how structural racism created the pandemic’s outsize impact on marginalized groups. Age-adjusted infection, hospitalization, and death rates for people of color in the United States
were higher
than those of white Americans, for example.
One big question for health researchers is how...
Did democracy have a separate origin in the Americas?
Democracy is widely understood to have arisen in the Mediterranean world about 2,500 years ago before spreading through cultural contact to other parts of the globe. But new research from the University of Georgia Laboratory of Archaeology, together with its partners in the Muscogee Nation, indicates that inhabitants of the Americas may have been practicing democratic-style collective governance...

2010 Deepwater Horizon accident did not harm BP's long-term stock market returns
A new analysis of the aftermath of the deadly 2010 Deepwater Horizon accident suggests that, while the reputation of BP—the oil and gas company responsible for the event—declined through 2017, its stock market returns were not significantly affected in the mid- to long-term. William McGuire of the University of Washington in Tacoma and colleagues present these findings in the open-access...
Dog-owner relationship appears similar for dogs born in Canada versus imported there
Contrary to some beliefs about internationally sourced dogs, a new survey analysis has found no evidence for a poorer relationship between Canadian dog owners and dogs born outside of Canada versus in Canada. Kai von Rentzell of the University of British Columbia in Vancouver, Canada, and colleagues present these findings in the open-access journal PLOS ONE on June 15, 2022.

Some countries still struggle to win EU funding despite programs to give them a leg up
The European Union has had some success leveling the playing field for countries that struggle to attract research funding, but certain countries still lag behind, according to an EU auditing body’s assessment. The “widening measures” aimed at giving stragglers a leg up can only go so far without matching efforts from those countries, says the report from the European Court of...
