A sand-dwelling new species of the moonseed plant genus Cissampelos from the Americas

A sand-dwelling new species of the moonseed plant genus Cissampelos from the Americas
2014-06-05
(Press-News.org) Researchers from the Missouri Botanical Garden have discovered in dry forests and transient sand dunes in Bolivia and Paraguay, a new plant species in the moonseed family Menispermaceae. The discovery was reported in the open access journal PhytoKeys.

The new species was described in the genus Cissampelos, which includes vining species that for the most part are found in disturbed habitats of the tropical and subtropical regions of the World.

This new Cissampelos is morphologically unique by its small leaves, its 8 anther-cells in the male flowers, and a large endocarp–a bony tissue surrounding the curved seed–obscurely ornamented.

The new species bears the name arenicola alluding to its preference for sand dune and dry forest habitats. Interestingly, the new species is superficially similar in habit to C. capensis a southern African taxon that also found in dry habitats.

As typical of most members of the Menispermaceae family, plants in the genus Cissampelos are also dioecious, with their male and female, mostly inconspicuous flowers found in different individuals.

The study by Dr. Rosa Ortiz and Dr. Michael Nee notes that the dioecious condition and increasing land transformation of its transient habitat may make this newly described species potentially vulnerable to extinction.

Scientists discover the basis of allergic reactions

2014-06-05
Allergies in humans and animals are on the increase. An allergic reaction may cause unpleasant symptoms like hay fever, food intolerance or skin rashes. Allergic reactions may also cause acute and life-threatening symptoms, such as asthma or anaphylactic shock. A single pollen protein is responsible for allergies One of the most well known allergens, i.e. substances that cause allergies, is so-called "Bet v 1" from birch pollen (Betula verrucosa). The protein was first produced artificially in the laboratory 25 years ago in Vienna, and is being used as an allergen ...

Shorter TB treatment regimens will reduce cost for patients and their families

2014-06-05
Shorter TB treatment regimens will reduce the out-of-pocket expenses incurred by both patients and their family members, who often act as the patients' guardians. In addition, shorter TB regimens may allow an earlier return to productive activities for patients and their families. These conclusions come from an international alliance of researchers, led by the Liverpool School of Tropical Medicine (LSTM), who carried out a comparative study in Tanzania and Bangladesh looking at the out-of-pocket costs incurred by TB patients in both countries. These patients were taking ...

App paired with sensor measures stress and delivers advice to cope in real time

2014-06-05
Computer scientists at Microsoft Research and the University of California, San Diego have developed a system that combines a mobile application and sensor to detect stress in parents and delivers research-based strategies to help decrease their stress during emotionally charged interactions with their children. The system was initially tested on a small group of parents of children with ADHD. The system, called ParentGuardian, is the first to detect stress and present interventions in real-time—at the right time and in the right place. It combines a sensor worn on the ...

NIDA review summarizes research on marijuana's negative health effects

2014-06-05
The current state of science on the adverse health effects of marijuana use links the drug to several significant adverse effects including addiction, a review reports. The article, published today in the New England Journal of Medicine, is authored by scientists from the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health. The review describes the science establishing that marijuana can be addictive and that this risk for addiction increases for daily or young users. It also offers insights into research on the gateway theory indicating ...

Report supports shutdown of all high seas fisheries

2014-06-05
Fish and aquatic life living in the high seas are more valuable as a carbon sink than as food and should be better protected, according to research from the University of British Columbia. The study found fish and aquatic life remove 1.5 billion tonnes of carbon dioxide from the atmosphere every year, a service valued at about $148 billion US. This dwarfs the $16 billion US paid for 10 million tonnes of fish caught on the high seas annually. "Countries around the world are struggling to find cost effective ways to reduce their carbon emissions," says Rashid Sumaila, ...

AUDIO: Edward Awh briefly describes the finding of his study on tracking early processing of working memory, and the differences between EEG and fMRI is studying the process. (41 seconds) Click here for more information. EUGENE, Ore. -- (June 5, 2014) -- University of Oregon researchers have tapped the rhythm of memories as they occur in near real time in the human brain. Using electroencephalogram (EEG) electrodes attached to the scalps of 25 student subjects, a UO team led by ...

American Aging Association Meeting presents latest developments in aging research

2014-06-05
The 43rd Annual Meeting of the American Aging Association (AGE) held May 30-June 2, 2014, at the Westin Riverwalk Hotel in San Antonio, Texas, featured the latest scholarship and research findings in the field of aging research from more than 70 leading experts. The event has long been recognized as a launching pad for researchers to share cutting-edge discoveries into the underlying mechanisms of the causes of aging as well as the possible breakthroughs in finding ways to increase healthspan. "The talks at this year's meeting were of exceptionally high quality with really ...

Protecting mainland Europe from an invasion of grey squirrels

2014-06-05
The first genotyping of grey squirrels sampled from Italy and the UK shows a direct link between their genetic diversity and their ability to invade new environments. In this new study, published in Diversity and Distributions, an international team of scientists from Imperial College London and the Zoological Society of London compared 12 DNA markers from grey squirrels (Sciurus carolinensis) in Piedmont in Northern Italy with the same markers from squirrel populations in Northern Ireland, Northumberland and East Anglia. After correlating genetic diversity against ...

Healthy tissue grafted to the brains of Huntington's patients also develops the disease

2014-06-05
Quebec City, June 5, 2014—A recent study published in Annals of Neurology reports that healthy human tissue grafted to the brains of patients with Huntington's disease in the hopes of treating the neurological disorder also developed signs of the illness, several years after the graft. This discovery will have profound implications on our understanding of the disease and how to treat it, and may also lead to the development of new therapies for neurodegenerative disorders. Huntington's disease is a hereditary illness that causes the progressive breakdown of nerve cells ...

Psychologists find that entitlement predicts sexism, in both men and women

2014-06-05
Entitled attitudes appear to be linked to sexism—even among women, according to a personality study by psychologists from Case Western Reserve University and San Diego State University. In general, entitled men are more likely to endorse hostile views of women and entitled women are more likely to endorse views of women as frail and needing extra care. The researchers found that, for men, entitlement was associated with hostile views of women. Entitled men were more likely to endorse views of women as manipulative, deceptive, and untrustworthy—attitudes, which past ...
