Intermittent fasting protects against liver inflammation and liver cancer      (via sciencedaily.com)     Original source 

Fatty liver disease often leads to chronic liver inflammation and can even result in liver cancer. Scientists have now shown in mice that intermittent fasting on a 5:2 schedule can halt this development. The fasting regime reduces the development of liver cancer in mice with pre-existing liver inflammation. The researchers identified two proteins in liver cells that are jointly responsible for the protective effect of fasting. An approved drug can partially mimic this effect.

Bee body mass, pathogens and local climate influence heat tolerance      (via sciencedaily.com)     Original source 

How well bees tolerate temperature extremes could determine their ability to persist in a changing climate. But heat tolerance varies between and within populations, so entomologists examined bee physical traits to understand how these traits interact with environmental conditions, pathogens and other factors.

Free-forming organelles help plants adapt to climate change      (via sciencedaily.com)     Original source 

Plants' ability to sense light and temperature, and their ability to adapt to climate change, hinges on free-forming structures in their cells whose function was, until now, a mystery. Researchers have now determined how these structures work on a molecular level, as well as where and how they form.

First effective treatment found for spitting cobra snakebite      (via sciencedaily.com)     Original source 

Scientists have discovered a new snakebite treatment to prevent the devastating tissue damage caused by African spitting cobra venom. Spitting cobra venom is incredibly potent and causes dermonecrosis, which presents as rapid destruction of skin, muscle and bone around the site of the snakebite, and can lead to permanent injuries and disfigurements, including limb loss and amputations in extreme cases. Using the repurposed small molecule drug varespladib to block one of the two major dermonecrosis-causing toxins in spitting cobra venom prevents skin and muscle damage. Each year, it is estimated that snakebite causes long term detrimental effects in around 400,000 people across the world, with a substantial proportion of those in Africa the result of spitting cobra bites.

Hubble views a galaxy with a voracious black hole      (via sciencedaily.com)     Original source 

Bright, starry spiral arms surround an active galactic center in a new NASA Hubble Space Telescope image of the galaxy NGC 4951. Located in the Virgo constellation, NGC 4951 is located roughly 50 million light-years away from Earth. It's classified as a Seyfert galaxy, which means that it's an extremely energetic type of galaxy with an active galactic nucleus (AGN).

Genomes of 'star algae' shed light on origin of plants      (via sciencedaily.com)     Original source 

Land plants cover the surface of our planet and often tower over us. They form complex bodies with multiple organs that consist of a broad range of cell types. Developing this morphological complexity is underpinned by intricate networks of genes, whose coordinated action shapes plant bodies through various molecular mechanisms. All of these magnificent forms burst forth from a one-off evolutionary event: when plants conquered Earth's surface, known as plant terrestrialization.
