Can galaxies exist without dark matter?
The nature of science is learning and revision. Our understanding of existence involves fine-tuning, sometimes completely restructuring our knowledge to comprise new discoveries. Physics, medicine, chemistry, all improve on themselves by revising older ideas, such as it is with dark matter and its Read More...
Scientists create family tree of 27 million ancestors
If you had to guess, how many ancestors would you say that you had? If you consider that homo sapiens, a.k.a humans, came into existence on this Earth around 200,000 years ago that’s a lot of ancestors to add up. How many ancestors do you think you have? Scientists from The University of Oxford Read More...
What tiny water samples teach us about huge creatures
Environmental DNA (eDNA) has been a recent gold mine in research. We recently reported on how eDNA was captured from the air in a world first and how scientists were able to use this technique to distinguish zoo animals from it. This incredible tool can help ecologists study animal behavior and Read More...
Upcycling your "business," 5 uses of human waste

Europe’s first biorefinery uses algae to make jet biofuel
The global aviation industry is responsible for more than 2 percent of human-produced carbon dioxide emissions. To put a dent in that statistic, scientists have been actively searching for cost-effective and eco-friendly aviation fuels derived from natural resources. In recent years, microalgae Read More...
Mineral flowers spotted on Mars
As always at The Optimist Daily, we like to keep our readers up to date on exciting findings on Mars. Last time we reported on NASA’s perseverance rover stumbling across organic molecules. Now we want to bring to light a finding from another one of our interplanetary robot friends, the Curiosity Read More...
6 impactful changes you can make to help avoid climate crisis
When it comes to climate change, just reading the news can be overwhelming. Hearing about wildfires and droughts, considering greenwashing and corporate carbon emissions, it’s easy to become stressed without even leaving your house, to think that there’s nothing you can do as an individual to Read More...
City trees may trap more CO2 than we thought
It’s becoming common knowledge at this point that trees greatly benefit cities and the people that call them home. City trees and urban green areas regulate temperature, improve mental health and reduce loneliness for urbanites, clean the air and even reduce crime rates. Our tall, green friends Read More...
Offshore wind farms might reverse climate change effects and help sea life
As the demand for renewable energy gets higher and higher, offshore wind turbines will inevitably move further and further away from the shore. Fortunately, floating turbine technology will help facilitate this shift—but now, for the first time ever, areas of the UK continental shelf that are Read More...
Healthier soil means healthier food
We’ve written in the past about regenerative agriculture and how it benefits the planet. It’s a simple system of farming that involves plowing less, using cover crops, and diversifying to create healthier soil. The practice has made products that are 100 percent carbon negative, and it has Read More...
