Superbugs in the ocean: what beached whales can teach us about antibiotic resistance Researchers found that more than half of the bacteria collected from stranded cetaceans in the Philippines showed antimicrobial resistance to commonly used drugs.

If there was oxygen on a far away planet, how would we know? Scientists use computer models to simulate what oxygen would look like on far away planets and found a chemical signature that helps us tell the difference between oxygen from life and oxygen from other sources.

Do humans need to be altruistic to make it to Mars? Altruism is selfless action for the well-being of others. Philosophical ideas suggest that the vision of space settlement can be achieved by coordinated altruism over a long time.

Altruism, in principle, is selfless action for the well-being of others. Altruism may help us achieve our space exploration goals. Space agencies like NASA, SpaceX, and ESA  are funding new projects to commercialize asteroids, the Moon, and Mars. These projects READ MORE

Symbiotic fungi can save farm crops during droughts As many farms worldwide get less and less rainfall per year due to climate change, it is getting harder to keep plants alive in dry seasons. Luckily, the use of mycorrhizal fungi in farming may allow our food crops to find more water during droughts.

What should farmers do to deal with disappearing water? Add fungi to the soil! This recent study sheds light on the use of mycorrhizae to mitigate drought in the farming industry, which is facing increasingly intense water shortages every year.

Using a Chinese medicinal herb Psoralea fructus to aid the development of bones Corylin, a flavonoid molecule derived from a Chinese medicinal herb, is effective in stimulating the body to make osteoblasts, which are cells that form new bones.

Osteoblasts are cells that are responsible for bone formation. A lack of osteoblasts will cause osteoporosis – a disease that occurs when the body has too little bone. The current treatments for osteoporosis either slow down bone resorption, or promote READ MORE

Early Martian life may have used sulfur as an energy source Using an environment on Earth that simulates early Mars conditions, researchers found an abundance of bacteria that get their energy from sulfur-containing molecules, suggesting a new focus in the search for biosignatures on the Red Planet.

People with complex-PTSD report less social support than those with PTSD Poor social support is a risk factor for PTSD, but it is unknown if poor social support is also a risk factor for Complex PTSD. This study found that those with CPTSD are less likely than PTSD to describe themselves as having a strong social support system.

Poor social support is a risk factor for PTSD, but it is unknown if poor social support is also a risk factor for Complex PTSD. This study found that those with CPTSD are less likely than PTSD to describe themselves as having a strong social support system.

Deep-sea Mining Impacts on Diverse Ocean Ecosystems Microorganisms in the dark depths of the ocean turn minerals into food that supports unique ecosystems. When we mine those minerals, the microorganisms suffer, and we could lose valuable resources.

Sunlight does not reach the deepest parts of the ocean, but life still thrives in the darkness. Below depths of 200 meters, where sunlight cannot reach, some organisms eat organic material that falls from the sunlit zone. For these organisms, READ MORE

Scientists debunk what we knew about sperm movement New research finds we were looking at sperm all wrong. For 350 years, scientists believed sperm wiggled their tails side-by-side to create a whip-like motion. Using 3D technology, a study found sperm actually move by rolling around and spinning their heads like tops.

How Biology Writes Its Signature Scientists search for extraterrestrial life by looking for tell-tale signs of biologic activity including plant pigments and changes in atmosphere composition over time.

In recent decades the search for extraterrestrial life has seen major advancements in technology and methodology. The search for biosignatures on exoplanets around stars similar to ours has brought about new questions, such as: “How will we know life exists READ MORE
