Bugs in boxes show difficulty of predicting invaders' progress
A study in today's Science by University of California and University of Colorado researchers suggests it won't be as easy as some had hoped to catalog all the factors that influence the spread of an invading species. If it is difficult to predict the course of an invasion, it will be difficult to control it. And there are hundreds of destructive invaders in the US alone, from kudzu to zebra mussels to the light brown apple moth. (2009-09-18)

An ecological invasion mimics a drunken walk
A theory that uses the mathematics of a drunken walk describes ecological invasions better than waves, according to Tim Reluga, associate professor of mathematics and biology, Penn State. (2017-01-09)

Moths with a nose for learning
Researchers at the National Institutes of Health, the Chinese University of Hong Kong and NIST have discovered that when training insects, the process of building associations is not a simple matter of strengthening connections through reinforcement. Understanding how associations are built between stimuli and behavior gives insight into the nature of learning and could inform the design of artificial (2008-10-02)

No more 'superbugs'? Maple syrup extract enhances antibiotic action
Antibiotics save lives, but there is a downside to their ubiquity. High doses can kill healthy cells along with bacteria, while also spurring the creation of 'superbugs' that don't respond to known antibiotics. Now, researchers report a natural way that could reduce antibiotic use without sacrificing health: a maple syrup extract that increases the potency of these medicines. They present their work today at the 253rd National Meeting & Exposition of the American Chemical Society. (2017-04-02)

In-cell molecular sieve from protein crystal
Scientists at Tokyo Institute of Technology, RIKEN, and Kyoto Institute of Technology have applied rational crystal design to create protein crystals with extended porous network to accumulate exogenous molecules inside living cells. This work lays a foundation for engineering of stable self-assembling crystalline porous materials which can concentrate and preserve bioactive substances in various cell types. (2017-02-09)

Study finds children are exposed to pesticides
Pre-school children in agricultural communities may be exposed to high levels of pesticides. University of Washington scientists found that 56 percent of children of farm workers had exposures beyond federal levels to a pesticide. The rate of exposure among children whose parents were not farm workers was still 44 percent. (2000-04-23)

A plastic-eating caterpillar
Generally speaking, plastic is incredibly resistant to breaking down. That's certainly true of the trillion polyethylene plastic bags that people use each and every year. But researchers reporting in Current Biology on April 24 may be on track to find a solution to plastic waste. The key is a caterpillar commonly known as a wax worm. (2017-04-24)

To thin or not to thin
Recent studies show that thinning of young forests can benefit the development of old-growth characteristics and the diversity of plants and animals, but only if methods are used that protect and promote the development of shrubs, hardwoods, and large or old trees. (2002-11-21)

Newly discovered Xenomorph wasp has alien-like lifecycle
A University of Adelaide PhD student has discovered a new species of wasp, named Xenomorph because of its gruesome parasitic lifecycle that echoes the predatory behaviour of the Alien movie franchise monster. (2018-06-27)

An artificial diet may make it easier to rear insects
Raising insects for research can be difficult because members of many species are picky eaters, but Canadian entomologists have found a solution for rearing moths and possibly other insects. (2016-02-09)

Species on the move
A total of 55 animal species in the UK have been displaced from their natural ranges or enabled to arrive for the first time on UK shores because of climate change over the last 10 years (2008-2018) -- as revealed in a new study published today by scientists at international conservation charity ZSL (Zoological Society of London). (2019-07-18)

Could climate change cause infertility?
A number of plant and animal species could find it increasingly difficult to reproduce if climate change worsens and global temperatures become more extreme -- a stark warning highlighted by new scientific research. (2019-04-15)

Hepatic injury in cholelithiasis and cholecystitis
The research team investigated the acute transient hepatocellular injury in patients with cholelithiasis and cholecystitis but no evidence of choledocholithiasis. They found that acute hepatocel lular injury in cholelithiasis and cholecystitis without choledocholithiasis is mild and transient. Hyperbilirubinemia and leukocytosis may predict severe inflammatory changes in the gallbladder. (2009-08-25)

Pushing the boundaries
Researchers at Johns Hopkins have established a high-efficiency cell-cell fusion system, providing a new model to study how fusion works. The scientists showed that fusion between two cells is not equal and mutual as some assumed, but, rather, is initiated and driven by one of the fusion partners. (2013-03-07)
