Equisetum - Scouring Rush Is The Oldest Extant Genus Of Land Plant?

Equisetum - Scouring Rush Is The Oldest Extant Genus Of Land Plant?

May 05 2011 | comment(s)

Over 100 million years ago, late Mesozoic forests were chock full of a diverse group of plants of the class Equisetopsida, though only one genus, Equisetum, commonly called scouring rush or horsetail, still exists today.  

It is unclear about the evolutionary beginnings of the genus Equisetum - molecular dating places the divergence of the 15 extant species of the genus around 65 million years ago but the fossil record had it earlier than that, around 136 million years ago.
Autism Overdiagnosed Or Undiagnosed?

Autism Overdiagnosed Or Undiagnosed?

May 04 2011 | comment(s)

A community survey in England identified people with autism or asperger's syndrome  and found none of them knew they have it.    And autism turned out to be more prevalent in males with lower education and in government housing.

Is autism causing people to have lower education and jobs or has the umbrella gotten so large it has become a blanket diagnosis for everyone not successful?

The results from the first ever general population survey of autism in adulthood. They are based on a two phase epidemiological survey in England (7,461 screening interviews; 618 diagnostic) carried out in 2007. The findings are in the Archives of General Psychiatry.
Phylogeny - Rice Did Originate In China

Phylogeny - Rice Did Originate In China

May 03 2011 | comment(s)

Rice, the eponymous food of Asia, originated in China, and domesticated rice may have first appeared as far back as approximately 9,000 years ago in the Yangtze Valley of China. Previous research suggested domesticated rice may have two points of origin, India as well as China.

The genome researchers used large-scale gene re-sequencing to re-assess the phylogeny, or evolutionary history, of domesticated rice using previously published datasets, some of which have been used to argue that indica and japonica rice have separate origins. Using newer computer algorithms, however, the researchers concluded these two species have the same origin because they have a closer genetic relationship to each other than to any wild rice species found in either India or China.
Acetaminophen Overdose May Be Painkiller Confusion

Acetaminophen Overdose May Be Painkiller Confusion

Acetaminophen overdose has become the leading cause of acute liver failure in the U.S.  How is that possible, when ingredients are printed clearly on the labels, along with warnings?  

Acetaminophen's is in more than 600 over-the-counter and prescription medicines and people take billions of doses of over-the-counter pain relievers every year, but many do not pay attention to the active ingredients they contain, such as acetaminophen, according to a new Northwestern Medicine study.

The first observatory experiment to study the dynamic microbial life inside Earth's crust has just been completed.  During the four-year subsurface experiment, the research team deployed the first in situ experimental microbial observatory systems below the flank of the Juan de Fuca Ridge, which is located off the coast of Washington (U.S.) and British Columbia (Canada).

Excessive Doses Of Thyroid Drugs Linked To Increased Risk Of Fractures In Elderly

Excessive Doses Of Thyroid Drugs Linked To Increased Risk Of Fractures In Elderly

Apr 30 2011 | comment(s)

Too many older adults are taking "excessive" doses of drugs for thyroid problems and that has been linked to an increased risk of fractures, according to a new study.   The study raises concern that treatment targets may need to be modified in the elderly.
