More than 66 million years ago, an asteroid impact led to the extinction of almost three-quarters of life on Earth. The little life that was left had to struggle, and research into its tenacity can provide key insights into how organisms survive environmental challenges. In a new study, scientists at Bigelow Laboratory for Ocean Sciences discovered how some species of single-celled algae lived through the mass extinction, a finding that could change how we understand global ocean processes.
Coccolithophores, like most algae, are photosynthetic and utilize the sun’s energy to make food. However, the aftermath of the asteroid impact was thought to have blanketed the planet with several months of darkness, a death sentence for most of the world’s photosynthetic organisms. In combination with other fallout effects, this caused the extinction of more than 90 percent of all coccolithophore species, some of the most influential organisms in the ocean. However, others endured.
As part of the new study, the team conducted laboratory experiments that showed some coccolithophores could survive without light. This revealed that the organisms must have another way to produce the energy and carbon that they need.
The study revealed how some coccolithophore species could use previously unrecognized organic compounds as carbon sources instead of carbon dioxide, which is what plants usually use. They can process dissolved organic compounds and immediately utilize them in a process called osmotrophy. The findings may explain how these organisms survive in dark conditions, such as after the asteroid impact, or deep in the ocean beneath where sunlight can reach.
The research was published in the journal New Phytologist and co-authored by two other researchers at Bigelow Laboratory, Senior Research Scientist William Balch and Senior Research Associate David Drapeau. It has far-reaching implications for life in the ocean.
Coccolithophores are integral to processes that control the global ocean and atmosphere, including the carbon cycle. They take in dissolved carbon dioxide from the atmosphere, which gets transported to the ocean floor when they die.
Coccolithophores also play an important role in mitigating ocean acidity, which can negatively affect organisms like shellfish and corals. The single-celled algae remove carbon from the water to build protective mineral plates made of limestone around themselves, which sink when they die. The process effectively pumps alkalinity deeper into the ocean, which chemically bolsters the water’s ability to resist becoming more acidic.
The new study revealed that the algae also take in carbon from previously unrecognized sources deeper in the water column. This could connect coccolithophores to a new set of global processes and raises fundamental questions about their role in the ocean.
The researchers next want to perform ocean experiments to observe how coccolithophores take in nutrients in their natural environment, especially in the dark. Godrijan hopes her work will help reveal more about the organisms, their significance, and their complex role on our planet.

Since the ME64 is built on the new FlexATX design, the board is quite small. It's design, however is nearly impeccable as all the connectors and jumpers are just where you'd expect to find them. The manual also come into play here as it walks you through setting up in a thorough step-by-step style that is simple, clear, and concise but doesn't insult your intelligence. From the proper installation of the universal retention clips to installing the proper software drivers, the manual covers everything in enough detail so that you feel as though you understand the system board well before your first boot.
Since the idea behind the ME64 does not fit the high-performance market, the use of oversized coolers shouldn't be a concern and the boards diminutive size makes their use a bit difficult but the board easily supports two full-length expansion cards providing you aren't using the UPT slot. The BIOS auto-detects the default CPU core voltage and front side bus frequency but offers a jumpered over-ride to force the FSB to 66, 100 or 133MHz. Shuttle also includes an ICH voltage jumper that can increase the ICH voltage from its default 3.3v to 3.9v if you have certain IDE devices which require increased voltage. Other jumper settings you'll want to take notice of are the power on by either PS/2 or USB keyboard or mouse and the BIOS boot-block protection jumper.Hey everyone and happy Hump Day! I recently just received the sweetest ModCloth Haul of all time – a box that went up to my shoulders filled with shoes for me! That’s right, I got FOUR pairs of ModCloth shoes for SEVENTY DOLLARS thanks to their end of summer sale. I stocked up on cute boots and killer wedges for a fraction of their original cost. I could not be happier with my purchases so take a look and let’s discuss:
^^^ PRETTY!!!!
My relationship with ModCloth is for the most part, nonexistent. Their prices just do not fit into my Lil Red Lifestyle of ballin on a budget so I just admire all of their gorgeous clothes and accessories from afar. I constantly lust over all of the prettiness that ModCloth has to offer and when the end of summer and winter come around, I religiously check the site to see when their amazing end of season sales take place. Usually around these times, the out of season items are marked down and an additional percentage is taken off, too. So, needless to say, when I learned that ModCloth’s sale items were an extra FORTY PERCENT OFF, homegirl just had to jump on the opportunity.
Jump on the opportunity? Psh, more like a pounce on said opportunity. I scoured the sale items and clicked on anything that tickled my fancy. After all, the prices were right! I ended up with two funky pairs of wedges, a penny loafer wedge, and my beautiful, beloved, gorgeous star studded booties. Said booties are actually what I would like to discuss today because there’s kind of a funny story behind them considering this was the third time that I ordered them. Let me explain…
I’ve been hungrily staring at these amazing booties on my laptop screen for the better part of two months. As soon as they got marked down, my mom generously offered to pay for them as an extra birthday present. As soon as “extra birthday present” traveled from my mom’s mouth and into my ears, I was on the computer and ordering the boots as quickly as my little fingers could. The boots arrived. They were perfect. End of story? Eh, not quite.
Literally three days after my order was placed, the boots were marked down further. *Sigh* So I had to do the old rebuy and return trick to get the better price. The boots arrived, again. They were still perfect. And the more expensive pair got returned. End of story?! Still no.
While browsing the sale pages, there they were. My star studded boots were marked down even further. *You’ve got to be freaking kidding me* Thankfully, I was still within the thirty day
