The Lacey Act, introduced in 1900 by Republican Congressman John F. Lacey of Iowa, was originally designed to stop illegal game across state borders but was then expanded, notably by President Ronald Reagan, to include illegal logging and breaking the laws of foreign governments.

The LHCb experiment collaborators at the Large Hadron Collider have announced discovery of two new particles in the baryon family.

The particles, known as the Xi_b'^- and Xi_b*^-, were predicted to exist by the quark model but had never been seen before. A related particle, the Xi_b*⁰, was found by the CMS experiment at CERN in 2012. 

Bacteria are everywhere and so efforts to make cleaner energy using them are ongoing.

A report today shows how electrons hop across otherwise electrically insulated areas of bacterial proteins, and that the rate of electrical transfer is dependent on the orientation and proximity of these electrically conductive 'stepping stones'. It is hoped that this natural process can be used to create viable 'bio batteries' which could produce energy for portable technology such as mobile phones, tablets and laptops - powered by human or animal waste. So using your tablet on the toilet would then make even more sense.

It’s official: men are better writers than women.

The news came as something of a shock to a hardened feminist such as myself, but a quick survey of prescribed and suggested texts set for senior English in most Australian states demonstrates this is a fact routinely taught to teenagers in school.

Historical acid deposits have greatly reduced calcium levels in Canadian lakes and that is dramatically impacting populations of calcium-rich plankton such as Daphnia - water fleas that dominate these ecosystems. 

It is commonly believed that one key issue in brain again is that it becomes less flexible - plastic - and that learning may therefore become more difficult.

A new study contradicts that and shows that plasticity did occur in seniors who learned a task well, it just occurred in a different part of the brain than in younger people.

When many older subjects learned a new visual task, the researchers found, they unexpectedly showed a significantly associated change in the white matter of the brain. White matter is the the brain's "wiring," or axons, sheathed in a material called myelin that can make transmission of signals more efficient. Younger learners, meanwhile, showed plasticity in the cortex, where neuroscientists expected to see it.

Scientists have found that seed dormancy, a property that prevents germination when conditions are not right, was present in the first seeds 360 million years ago.

Seed dormancy is a phenomenon that has intrigued naturalists for decades, since it conditions the dynamics of natural vegetation and agricultural cycles. There are several types of dormancy, and some of them are modulated by environmental conditions in more subtle ways than others.

In an article published in the New Phytologist journal, the scientists studied the evolution of dormancy in seeds using more than 14.000 species. 

Time is relative. What is a long time to humans is nothing to a mountain. Like humans, mountains usually burst on the scene, then they stand tall and finally age wears them down and their sharp features soften and they become grow shorter and rounder.

Not all mountains, though. The Gamburtsev Mountains in the middle of Antarctica look quite young for their age. Though the Gamburtsevs were discovered in the 1950s, they remained unexplored until government budget increases and few things left above ground to explore led scientists to fly ice-penetrating instruments over the mountains 60 years later.

Women judge men by their shoes, that is no secret. Women colloquially say that they know how a man will treat them based on how much he cares about his footwear and (bonus tell: how he treats the waitress in a restaurant).

On a quest to design an alternative to the complex approaches currently used to produce electrons within microwave electron guns, a team of researchers have demonstrated a plug-and-play solution capable of operating in a high-electric-field environment with a high-quality electron beam.

Unfamiliar with microwave electron guns? They provide a higher current and much higher quality electron beams than conventional DC guns for X-ray sources . Beams of this sort are also used in free-electron lasers, synchrotrons, linear colliders and wakefield accelerator schemes. But the electron emission mechanisms involved -- laser irradiation of materials (photocathodes) and heating of materials (thermionic cathodes) -- tend to be complex, bulky or extremely expensive.
