Plants recognize their siblings, biologists discover

...rs. “The ability to recognize and favour kin is common in animals, but this is the first time it has been shown in plants” said Susan Dudley, associate professor of biology at McMaster University in Hamilton, Canada. “When plants share their pots, they get competitive and start growing more roots, which ...

Penn researchers link cell's protein recycling systems

...seases because accumulation of toxic proteins is a common underlying feature of age-related neurodegeneration.” Taylor and his group study fruit flies in which the proteasome is disabled by a genetic mutation, which results in neurodegeneration. They use the fly eye, a neuron-rich tissue, as a surrogate...

Bacteria ferry nanoparticles into cells for early diagnosis, treatment

Researchers at Purdue University have shown that common bacteria can deliver a valuable cargo of "smart nanoparticles" into a cell to precisely position sensors, drugs or DNA for the early diagnosis and treatment of various diseases. The approach represents a potential way to overcome hurdles in delive...

Study finds mix of disease processes at work in brains of most people with dementia

Risk of stroke doubles if diagnosed with Type 2 diabetes

...s than for older persons. As it has been more common to study stroke prevalence within 10 years after diagnosis, this is the first study to specifically examine stroke-related outcomes immediately after the diagnosis of and initiation of treatment for Type 2 diabetes. Jeerakathil indicates it is pos...

Plastic that grows on trees

...at it was simpler to start with the fructose, less common in nature than glucose. Zhang and his team, working with a high-throughput reactor capable of testing 96 metal halide catalysts at various temperatures, discovered that a particular metal — chromium chloride — was by far the most effective at conv...

Marine phytoplankton changes form to protect itself from different predators

...nces, researchers report the first evidence that a common species of saltwater algae – also known as phytoplankton – can change form to protect itself against attack by predators that have very different feeding habits. To boost its survival chances, Phaeocystis globosa will enhance or suppress the formati...

Research finds that circadian rhythms dominate all life functions

...g environment. "When we standardize genes onto a common scale that measures levels of expression, we could not find a single gene that did not oscillate," Ptitsyn said. ...

CU study reveals why starling females cheat

...s on her own. But because superb starlings, a bird common to East Africa, are cooperative breeders, females have more incentive to stray, said Rubenstein, because even if she is caught cheating, she still may get help from other group members. Yet, superb starlings tend to stray much less often than other c...

Genome of Clostridium botulinum reveals the background to world's deadliest toxin

...and only 16 per cent of the C. botulinum genes are common to all five. Our findings emphasise just how different clostridia are from each other." C. botulinum toxin stops nerves from working — the basis of its use in medicine to control tremors and in cosmetic treatments. For the prey of its opportunis...

Recently inflammation and infectious agents have been shown to play an important role in the onset of acute cardiovascular events. The online, open-access PLoS ONE publishes a new study on the relationship between Cytomegalovirus i...

New designer lipid-like peptide with lipid nanostructures for drug delivery systems

These lipid-like peptides have excellent potential to solubilize membrane proteins and enzymes, and - as now demonstrated - can also be utilized to stabilize different self-assembled...

Common treatment for methamphetamine overdose may damage brain cells

A common antipsychotic drug used in emergency rooms to treat methamphetamine overdose damages nerve cells in an area of the brain known to regulate movement, a new study shows. The findings, derived from experiments with rats, indicate that only the combinat...

For many insects, winter survival is in the genes

... related to the flesh fly. Each insect is a fairly common agricultural pest: the gypsy moth, the European corn borer, the walnut husk maggot, the apple maggot and the tobacco hornworm. Collectively, these species cause millions of dollars of damage annually. Hsp70 was active while all of the insects were...
