It’s not just fish, plastic pollution harms the bacteria that help us breathe
Posted by Xavier Rosseel in category: biological
“We looked at a group of tiny, green bacteria called Prochlorococcus which is the most abundant photosynthetic organism on Earth, with a global population of around three octillion (~1027) individuals,” says Sasha.
Ten per cent of the oxygen we breathe comes from just one kind of bacteria in the ocean. Now laboratory tests have shown that these bacteria are susceptible to plastic pollution, according to a study published in Communications Biology.
“We found that exposure to chemicals leaching from plastic pollution interfered with the growth, photosynthesis and oxygen production of Prochlorococcus, the ocean’s most abundant photosynthetic bacteria,” says lead author and Macquarie University researcher Dr. Sasha Tetu.

The Rise of India’s New Billionaires (And the Fall of the Old)
Posted by Derick Lee in categories: business, economics
While old business clans continue to dominate India’s rich lists, a tenfold expansion in its economy since its opening in the 1990s has spawned new tycoons in fields like technology. The number of billionaires in India more than doubled to 119 between 2013 and 2018, according to Knight Frank. And the country will lead the global growth in ultrahigh net worth individuals, with its numbers rising 39 percent to 2,697 by 2023, the researcher estimates.
India is going through one of the greatest periods of wealth creation — and destruction — all at the same time.
A new breed of self-made entrepreneurs is vaulting into the ranks of the wealthy, offsetting billions lost by debt-burdened industrialists and members of the country’s old dynasties. The changes are set to help India’s ultra-rich population grow at the world’s fastest pace.

Common food additive E171 found to affect gut microbiota
Posted by Paul Battista in categories: biotech/medical, food, health, nanotechnology
University of Sydney research provides new evidence that nanoparticles, which are present in many food items, may have a substantial and harmful influence on human health.
The study investigated the health impacts of food additive E171 (titanium dioxide nanoparticles) which is commonly used in high quantities in foods and some medicines as a whitening agent. Found in more than 900 food products such as chewing gum and mayonnaise, E171 is consumed in high proportion everyday by the general population.
Published in Frontiers in Nutrition, the mice study found that consumption of food containing E171 has an impact on the gut microbiota (defined by the trillions of bacteria that inhabit the gut) which could trigger diseases such as inflammatory bowel diseases and colorectal cancer.

CRISPR might soon create spicy tomatoes
Posted by Quinn Sena in categories: biotech/medical, genetics
Looking for perfect heat and lots of it? Gene engineers in Brazil think they might be able to create eye-watering tomatoes.
Hot stuff: Even though chili peppers and tomato plants diverged from a common ancestor millions of years ago, tomatoes still possess the genetic pathway needed to make capsaicinoids, the molecules that make chilis hot.
Now, Agustin Zsögön from the Federal University of Viçosa in Brazil writes in the journal Trends in Plant Science that gene-editing tools like CRISPR could turn it back on.

This Hubble photo captures more than 265,000 galaxies in one image
Posted by Quinn Sena in category: cosmology
The image mosaic was created using 16 years’ worth of data from the Hubble Space Telescope, and it shows roughly 265,000 galaxies stretching back 13.3 billion years, to just 500 million years after the Big Bang.
Background: This isn’t the first Hubble deep-field image. The first one was released back in 1995, with further deep-field images following in 2003, 2004, and 2012. However, this is by far the most comprehensive. It was created by weaving together several of the previous Hubble photos. The image, dubbed the Hubble Legacy Field, represents 7,500 separate exposures. It contains about 30 times as many galaxies as the previous shots. The image above is just a section of the whole: you can see the full thing here.
A time machine: Because many of the galaxies Hubble captures are so far away, it has taken billions of years for their light to reach us. That makes the telescope a sort of time machine, letting us see galaxies as they were billions of years ago.

Study uncovers key mechanism that allows some of the world’s deadliest viruses to replicate
Posted by Quinn Sena in categories: biotech/medical, genetics
Viruses are masterful invaders. They cannibalize host cells by injecting their genetic material, often making thousands of copies of themselves in a single cell to ensure their replication and survival.
Some RNA viruses insert their genetic material as a single piece, while others chop it up into pieces. The latter are aptly named segmented viruses.
Such segmented RNA viruses—including several that cause human diseases like influenza—have been a longstanding enigma to researchers: How do they accomplish the precise copying and insertion of each segment? How do they ensure that individual segments are all copied by the same enzyme while ensuring that each segment can make different amounts of RNA? Such exquisite regulation is critical to make the correct levels of the viral proteins necessary for successful replication.
