No deliveries: How cells decide when to accept extracellular packages
- ScienceDaily
- 19/11/13 23:03
Endocytosis, a fundamental process that cells use to take in macromolecules, functions a lot like an airlock on a spaceship -- but squishier, says a researcher. Researchers have studied how cells initiate and perform endocytosis since the 1960s, but in a new article they finally describes how cells shut down this important cellular machinery. And their findings are not without controversy.

When reporting climate-driven human migration, place matters
- ScienceDaily
- 19/11/13 21:31
Location matters when talking about how climate might or might not be driving migration from Central America. Climate research in the dry corridor region revealed a complex pattern of change. If you average across the entire region you wouldn't see a trend going either way.
Multimaterial 3D printing manufactures complex objects, fast
- ScienceDaily
- 19/11/13 21:31
3D printing is super cool, but it's also super slow -- it would take 115 days to print a detailed, multimaterial object about the size of a grapefruit. A new method allows printing with up to 8 different inks in a fraction of the time, thanks to special printheads that can seamlessly switch inks up to 50 times per second.
Ancient Egyptians gathered birds from the wild for sacrifice and mummification

In ancient Egypt, sacred ibises were collected from their natural habitats to be ritually sacrificed, according to a new study.
Experts unlock key to photosynthesis, a find that could help us meet food security demands
- ScienceDaily
- 19/11/13 21:31
Scientists have solved the structure of one of the key components of photosynthesis, a discovery that could lead to photosynthesis being 'redesigned' to achieve higher yields and meet urgent food security needs.
Phage therapy shows promise for alcoholic liver disease
- ScienceDaily
- 19/11/13 21:31
Researchers linked a gut bacteria toxin to worse clinical outcomes in patients with alcoholic liver disease, and discovered that treatment with bacteriophages clears the bacteria and eliminates the disease in mice.
Could the mysteries of antimatter and dark matter be linked?
- ScienceDaily
- 19/11/13 21:30
Researchers have performed the first laboratory experiments to determine whether a slightly different way in which matter and antimatter interact with dark matter might be a key to solving both mysteries.
Researchers unravel protective properties of telomere t-loops
- ScienceDaily
- 19/11/13 21:30
Loops at the ends of telomeres play a vital protective role preventing damage to chromosomes, according to new research. The study showed how the winding and unwinding of 't-loops' at the end of telomeres prevents chromosomes from being recognized as DNA damage. The study also uncovered how this process is regulated.
Extinct giant ape directly linked to the living orangutan
- ScienceDaily
- 19/11/13 21:30
Researchers have succeeded in reconstructing the evolutionary relationship between a two million year old giant primate and the living orangutan. It is the first time genetic material this old has been retrieved from a fossil in a subtropical area. This allows the researchers to accurately reconstruct animal, including human, evolutionary processes way beyond the limits known today.
In states where recreational marijuana is legal, problematic use increased among adults and teens
- ScienceDaily
- 19/11/13 21:30
Problematic use of marijuana among adolescents and adults increased after legalization of recreational marijuana use, according to a new study from NYU Grossman School of Medicine and Columbia University Mailman School of Public Health.
Slowing the progression of multiple sclerosis
- ScienceDaily
- 19/11/13 21:30
Over 77,000 Canadians are living with multiple sclerosis, a disease whose causes still remain unknown. Presently, they have no hope for a cure. Researchers have now identified a molecule named ALCAM which, once blocked, delays the progression of the disease. Their results, obtained from in vitro human and in vivo mouse studies, could lead to the development of a new generation of therapies to...
Microparticles could help fight malnutrition
- ScienceDaily
- 19/11/13 21:30
Researchers have now developed a new way to fortify staple foods with these micronutrients by encapsulating them in a biocompatible polymer that prevents the nutrients from being degraded during storage or cooking. In a small clinical trial, they showed that women who ate bread fortified with encapsulated iron were able to absorb iron from the food.
Understanding transporter proteins at a single-molecule level
- ScienceDaily

New research reveals the mechanics of how some transporter proteins function with stunning specificity.
Predicting evolution: Not just 'survival of the fittest'
- ScienceDaily
- 19/11/13 21:30
A new method of 're-barcoding' DNA allows scientists to track rapid evolution in yeast. The approach has implications for the prediction of dominant viral strains.
Something old, something new in the ocean's blue
- ScienceDaily
- 19/11/13 21:30
Microbiologists have discovered a new metabolic process in the ocean. Ranging from molecular structures of individual genes and detection of their global distribution, their results give insight into the pathway process and its degradation products and thus provide valuable information for future calculations of the ocean`s carbon dioxide balance.
Tuna carbon ratios reveal shift in food web
- ScienceDaily
- 19/11/13 21:30
The ratio of carbon isotopes in three common species of tuna has changed substantially since 2000, suggesting major shifts are also taking place in the phytoplankton populations that form the basis of the ocean's food web, according to a new international study. Much of the change occurring in phytoplankton physiology and species composition may be driven by increased ocean stratification, an...
Precisely poking cells en masse to cure cancer
- ScienceDaily
- 19/11/13 21:30
A novel microfluidic device addresses one of the most costly steps in the engineered cell therapy manufacturing process, namely gene delivery. Deterministic mechanoporation, or DMP, uses fluid flow to pull each cell in a large population onto its own tiny needle. The flow is then reversed to release the cells from the needles, leaving a singular and precisely defined pore within each cell that...

Chitin-binding proteins override host plant's resistance to fungal infection
- ScienceDaily
- 19/11/13 18:48
A recent article studies chitin-binding proteins from a soilborne fungus (Verticillium nonalfalfae) that causes vascular wilt in plants. This fungus binds a particular protein (VnaChtBP) to chitin in order to abolish the host plant's chitin-triggered burst of reactive oxygen species and shield the fungus from being digested by the plant.
