Study: DNA corroborates “Well-man” tale from Norse saga
The "Well-man" likely had blue eyes, blond or light-brown hair, and hailed from southern Norway. A 12th-century Norse saga tells of an invading army from the south razing a castl.....»»
Invisible anatomy in the fruit fly uterus: New discoveries could have implications for fertility and pest control
You have likely not spent much time thinking about the uterus of the fruit fly, Drosophila melanogaster. But then, neither have most scientists, even though Drosophila is one of the most thoroughly studied lab animals. Now a team of biologists at the.....»»
Molecular study of newly discovered tardigrade species helps explain ability to withstand high doses of radiation
A team of biologists affiliated with several institutions in China has learned more about the means by which tardigrades are able to withstand high doses of radiation. In their study, published in the journal Science, the group focused on a newly fou.....»»
Climate scientists identify water requirements for climate mitigation through ecosystem restoration
Worldwide, deforestation and farming practices are responsible for the degradation of vital ecosystems. While there is a significant amount of interest in climate mitigation by restoring those degraded lands with forests and other ecosystems, it is u.....»»
New method achieves functional protein delivery into living cells
In cooperation with researchers from the China University of Petroleum, the working group of Dr. Werner Nau, Professor of Chemistry at Constructor University, has demonstrated the effectiveness of a new method of intracellular protein transport......»»
Research on how gut bacteria breaks down dietary fiber could lead to helpful new probiotics
There are trillions of bacteria in the human gut microbiome. When we eat fruits and vegetables, some of these bacteria break down the dietary fiber and provide us with metabolites, small molecules our body can use for energy or cell repair......»»
On the way to light-controlled medicine: Researchers elucidate the structure of specific photoreceptors
Researchers in biology and medicine have long dreamed of controlling the activities of cells without, for example, having to use chemicals. After all, in a structure as complex as an entire organism, unwanted side-effects can often arise......»»
Biologists discover a new fossil species of prehistoric fish
What do the ginkgo (a tree), the nautilus (a mollusk) and the coelacanth (a fish) all have in common?.....»»
Live-cell imaging under centrifugation: New method measures the forces that keep the nuclei of living cells centered
Using two specialized microscopes invented at the Marine Biological Laboratory (MBL), a team of researchers from Japan and the MBL have developed a new method to measure the forces that keep the nucleus centered within a living cell. The experiments.....»»
A much faster way to encode DNA with usable digital data
An international team of molecular biologists, computer scientists and physicists has found a way to encode useable digital data onto DNA strands 350 times faster than current approaches. In their study, published in the journal Nature, the group use.....»»

"Paleo-robots" provide an experimental approach for understanding how fish started to walk on land
The transition from water to land is one of the most significant events in the history of life on Earth. Now, a team of roboticists, paleontologists and biologists is using robots to study how the ancestors of modern land animals transitioned from sw.....»»
Students at Historically Black Colleges and Universities face barriers to medical school admission, study finds
There are 45.3 million African Americans living in the United States and they represent 13.6% of the U.S. population, according to the U.S. Census Bureau. But only 5.7% of physicians in the United States self-identify as Black, despite multiple effor.....»»
New technology illustrates bacterial "hibernation states"
Like hibernating bears, certain bacterial cells have the ability to shift into a "low-power" metabolic state in which they can stably survive without growing. This state is often seen in the context of antibiotic-resistant infections as bacteria form.....»»
An elegant switch regulates production of protein variants during cell division
Our cells contain thousands of proteins that have gone largely undetected and unstudied until recent years: these are variants of known proteins, which cells can make when their protein-building machinery interacts differently with the same stretch o.....»»
A multi-level breakthrough in optical computing—a faster, more efficient, and robust memory cell
