O'Regan says 30 million trees to be planted this year, two billion by 2030
A Liberal campaign pledge to plant two billion trees by 2030 finally seems to have taken root. Natural Resources Minister Seamus O'Regan announced Friday that 30 million trees will be planted this season out of the two billion his government promised to plant over the next 10 years during the 2019 federal election...
Magnetism drives metals to insulators in new experiment
Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal conductors only if temperatures are high enough; at low temperatures, they act like insulators and do not do a good job of carrying electricity. In other words, these unusual...
Social identity within the anti-vaccine movement
A study of more than 1,000 demographically representative participants found that about 22 percent of Americans self-identify as anti-vaxxers, and tend to embrace the label as a form of social identity.
Researchers investigate mining-related deforestation in the Amazon
If you're wearing gold jewelry right now, there's a good chance it came from an illegal mining operation in the tropics and surfaced only after some rainforest was sacrificed, according to a team of University of Wisconsin-Madison researchers and alumni who studied regulatory efforts to curb some of these environmentally damaging activities in the Amazon.
Fungus creates a fast track for carbon
Tiny algae in Earth's oceans and lakes take in sunlight and carbon dioxide and turn them into sugars that sustain the rest of the aquatic food web, gobbling up about as much carbon as all the world's trees and plants combined.
Why scientists want to solve an underground mystery about where microbes live
Though it might seem inanimate, the soil under our feet is very much alive. It's filled with countless microorganisms actively breaking down organic matter, like fallen leaves and plants, and performing a host of other functions that maintain the natural balance of carbon and nutrients stored in the ground beneath us.
Beyond synthetic biology, synthetic ecology boosts health by engineering the environment
There's a lot of interest right now in how different microbiomes—like the one made up of all the bacteria in our guts—could be harnessed to boost human health and cure disease. But Daniel Segrè has set his sights on a much more ambitious vision for how the microbiome could be manipulated for good: "To help sustain our planet, not just our own health."
Substantial carbon dioxide emissions from northern peatlands drained for crop cultivation
A new study shows that substantial amounts of carbon dioxide were released during the last millennium because of crop cultivation on peatlands in the Northern Hemisphere.

'Natural climate solutions' are available to help Canada meet emissions targets, new study says
Canada could reach one-third of its greenhouse gas reduction targets by making better use of its vast forests, prairies and wetlands, says a report by more than three dozen...
Five questions posed by Facebook’s two-year ban on Donald Trump
On Friday, Facebook announced that it would suspend former president Donald Trump from the social network for two years, until at least January 7, 2023, and said he would “only be reinstated if conditions permit.”
The announcement comes in response to recommendations last month from Facebook’s recently created Oversight Board. Facebook had hoped that the board would decide how to handle...
The U.S. Government’s Long-Awaited UFO Report Is Here. Its Findings? ¯\_(ツ)_/¯
The U.S. Navy pilots flying maneuvers in their F/A-18 Super Hornets in 2015 did not have to wait for yesterday’s leak of the classified government report on unidentified aerial phenomena (UAP)—better known as UFOs—to know that they were seeing things they could not explain outside their windscreens. The objects were, yes, saucer-shaped, and they were bobbing, darting and...
Quantum holds the key to secure conference calls
The world is one step closer to ultimately secure conference calls, thanks to a collaboration between Quantum Communications Hub researchers and their German colleagues, enabling a quantum-secure conversation to take place between four parties simultaneously.
Soft tissue measurements critical to hominid reconstruction
Accurate soft tissue measurements are critical when making reconstructions of human ancestors, a new study from the University of Adelaide and Arizona State University has found.
Study of past South Asian monsoons suggests stronger monsoon rainfall in the future
A new study of monsoon rainfall on the Indian subcontinent over the past million years provides vital clues about how the monsoons will respond to future climate change.
Early warning system for COVID-19 gets faster through wastewater detection and tracing

A new research paper builds on previous research of COVID-19 testing in municipal sewer systems and subsequent tracing the virus back to the source by more accurately modelling a system's treelike network of one-way pipes and manholes, and by speeding up the detection/tracing process through automatic sensors installed in specific manholes, chosen according to an easier-to-use algorithm.

An atom chip interferometer that could detect quantum gravity
- ScienceDaily
- 21/6/4 19:54
Physicists have created a quantum interferometer on an atom chip. This device can be used to explore the fundamentals of quantum theory by studying the interference pattern between two beams of atoms. Physicists describe how the device could be adapted to use mesoscopic particles instead of atoms. This modification would allow for expanded applications.

A genetic link has been discovered explaining why some people catch COVID but don't get sick. The gene is found three times as often in people who are asymptomatic. This is the first clear evidence of genetic resistance because the study compared severely affected people with an asymptomatic COVID group and used next generation sequencing to focus in detail and at scale on the HLA genes which are...
