Human social groups have a strange tendency to share responsibility for taking care of infants; parents, older siblings, and other adult relatives all help to nurture babies. The only other primates that take care of infants this way are marmosets, a group of small, highly social monkeys from South America. In another striking parallel to humans, infant marmosets also benefit from frequent feedback while learning their vocal calls.
Researchers report a new draft genome of Spinacia oleracea, better known as spinach. Additionally, the authors have sequenced the transcriptomes (all the RNA) of 120 cultivated and wild spinach plants, which has allowed them to identify which genetic changes have occurred due to domestication.
If every cell in our body is a factory, viruses are industrial spies who try to break in and take over. New findings about how one of the most mysterious types of spy - polyomaviruses -- accomplishes this feat could aid the fight against Merkel cell carcinoma, and diseases in organ transplant and cancer patients.
Researchers have figured out how a once-defeated bacterium has re-emerged to infect cotton in a battle that could sour much of the Texas and US crop. And it boils down to this: A smart bacteria with a sweet tooth.
Clostridium botulinum is the bacterium that causes the neurointoxication, which produces one of the most potent toxins on earth and is classified as a potential bioterrorism threat. While no cure exists -- and botulism treatment options are limited -- a serendipitous discovery may provide a new therapy that can stop the neurotoxin even in its more severe, advanced stages of action.
Scientists have assembled the 1.64 gigabytes genome of a deep-sea mussel, which is roughly equivalent to 50 percent of the size of human genome. This is the first decoded genome among all deep-sea macrobenthic animals, revealing a complete set of DNA.
Synthetic biology researchers have demonstrated a new method for digital information processing in living cells, analogous to the logic gates used in electric circuits. The circuits are the largest ever published to date in eurkaryotic cells and a key step in harnessing the potential of cells as living computers that can respond to disease, efficiently produce biofuels or develop plant-based chemicals.
Globally, every 30 seconds a diabetic has a limb amputated because of a non-healing wound. A molecule produced by a Thai liver parasite could be the solution to those non-healing wounds -- and scientists are now able to produce a version of the molecule on a large enough scale to make it available for laboratory tests and eventually clinical trials.
The snowy-feathered head and distinctive brown body of the bald eagle is a proud national symbol of the United States, adorning the country's currency and passports. The lion, known as 'King of the Beasts,' represents national strength and identity in several African countries. But, how are populations of the planet's most valued wildlife faring in the 21st century? How well are societies protecting the species they have chosen to embody their ideals and represent their national identity?
Scientists studying the genetics of Zika virus in Brazil and beyond has provided a new understanding of the disease and its rapid spread through space and time. The research has significant public health implications and has the potential to improve responses to future outbreaks.
With mosquito season looming in the Northern Hemisphere, doctors and researchers are poised to take on a new round of Zika virus infections. Now a new study explains how Zika virus entered the United States via Florida in 2016 -- and how it might re-enter the country this year.
A new study looks at how three varieties of camelina perform when grown in two different regions within the Great Plains. The end goal is to find the camelina variety that performs best in each location or environment -- beyond the genetics involved.
Our cells are rich in proteins which are potential targets for therapy. But study of these proteins' behavior, using externally delivered biomacromolecules, has often been stymied by the difficulty of gaining access to the interiors of living cells.
Is it possible to watch at the level of single cells how fish embryos become trout, carp or salmon? Researchers have successfully combined two very advanced fluorescence microscopy techniques. The new high-resolution light microscope permits fascinating insights into a cell's interior.
