Thirty new spider species found in one of China's richest biodiversity hotspots

Thirty new spider species found in one of China's richest biodiversity hotspots
2014-12-04
(Press-News.org) Scientists from the Institute of Zoology with the Chinese Academy of Sciences have devoted years of their careers to study the astounding diversity hidden in the depths of the Xishuangbanna tropical rain forests. In a recent paper published in the open access journal ZooKeys Prof. Shuqiang Li and his team reveal 30 new spider species, which constitutes a minor share of what is yet to be found in this biodiversity hotspot.

Xishuangbanna is situated in the southern part of Yunnan with the Lancang (Mekong) River flowing through it. The region is well-known for its rich biodiversity and is one of the few places in China that still maintains large tracts of tropical rain forest, which won its reputation as the "Kingdom of Tropical Fauna and Flora".

Xishuangbanna Tropical Botanical Garden (XTBG) is a comprehensive botanical research institution that belongs to the Chinese Academy of Sciences (CAS). It is famous for holding over 10 thousand species of tropical and subtropical plants.

But what animal species are hidden in this remarkable place? Studying the rich fauna of rainforests can be a great challenge due to the extreme diversity of species and the hardships posed by the specific terrain.

When it comes to spiders Prof. Li and his team have attempted to unveil this mystery. Using multiple collecting methods they have been collecting samples in an area called Huludao since 2006. Covering only about 200 hectare of Xishuangbanna, this area has yielded a collection of approximately 700 spider species.

Out of this impressive species diversity until now the team has published about 250 new spider species from Xishuangbanna alone, with the 30 currently described in ZooKeys being a part of their ongoing work. However, Prof. Li said there are still around 100 new spider species to be published soon.

"The amazing biological diversity we have witnessed during our work on spiders in Huladao is perhaps only a part of what Xishuangbanna tropical rain forests hold. Studying the flora and fauna in biodiversity hotspots like these attests for the importance of their preservations, and gives a sad insight of what was lost with the destruction of forests elsewhere", comments Prof. Li.

Are the benefits of breast milk stimulant worth the risk?

2014-12-04
Los Angeles, CA (Nov 4, 2014) Most women can make all the milk their baby needs, but some mothers turn to medications to help increase their supply. While some specialists encourage the off-label use of domperidone to stimulate breast milk production, some studies have suggested it may be related to negative side effects, including irregular heartbeat and sudden cardiac death. In a new article out today, researchers concluded that although domperidone can increase breast milk production, and there is no known risk to the babies who drink the milk, risks to women are still ...

Mini chromosomes that strengthen tumors

2014-12-04
Cancers are due to genetic aberrations in certain cells that gain the ability to divide indefinitely. This proliferation of sick cells generates tumors, which gradually invade healthy tissue. Therefore, current therapies essentially seek to destroy cancer cells to stop their proliferation. Through high-throughput genetic sequencing of glioblastoma cells, one of the most deadly brain tumors, a team of geneticists from the University of Geneva's (UNIGE) Faculty of Medicine discovered that some of these mutations are caused by supplemental extrachromosomal DNA fragments, called ...

Localized climate change contributed to ancient southwest depopulation

2014-12-04
PULLMAN, Wash.--Washington State University researchers have detailed the role of localized climate change in one of the great mysteries of North American archaeology: the depopulation of southwest Colorado by ancestral Pueblo people in the late 1200s. In the process, they address one of the mysteries of modern-day climate change: How will humans react? Writing in Nature Communications, WSU archaeologist Tim Kohler and post-doctoral researcher Kyle Bocinsky use tree-ring data, the growth requirements of traditional maize crops and a suite of computer programs to make ...

Technology breakthrough reveals cellular transcription process

2014-12-04
This news release is available in French. A new technology that reveals cellular gene transcription in greater detail has been developed by Dr. Daniel Kaufmann of the University of Montreal Hospital Research Centre (CRCHUM) and the research team he directed. "This new research tool offers us a more profound view of the immune responses that are involved in a range of diseases, such as HIV infection. At the level of gene transcription, this had been difficult, complex and costly to do with current technologies, such as microscopy," explained the University of Montreal ...

Dirt provides new insight into Roman burials

2014-12-04
The first scientific evidence of frankincense being used in Roman burial rites in Britain has been uncovered by a team of archaeological scientists led by the University of Bradford. The findings - published today in the Journal of Archaeological Science - prove that, even while the Roman Empire was in decline, these precious substances were being transported to its furthest northern outpost. The discovery was made by carrying out molecular analysis of materials previously thought to be of little interest - debris inside burial containers and residues on skeletal remains ...

Preliminary study suggests Parkinson's drugs safe for the heart

Vienna, Austria - 04 December 2014: Non-ergot derived dopamine agonists used to treat Parkinson's disease may be safe for the heart, according to preliminary research presented at EuroEcho-Imaging 2014 by Dr Hilal Erken Pamukcu, cardiologist at Ankara Diskapi Education and Research Hospital in Turkey. EuroEcho-Imaging is the annual meeting of the European Association of Cardiovascular Imaging (EACVI), a registered branch of the European Society of Cardiology (ESC), and is held 3-6 December in Vienna, Austria. Dr Erken Pamukcu said: "Parkinson's disease is a neurological ...

Medications for patients with first episode psychosis may not meet guidelines

Medications for patients with first episode psychosis may not meet guidelines
2014-12-04
Many patients with first-episode psychosis receive medications that do not comply with recommended guidelines for first-episode treatment, researchers have found. Current guidelines emphasize low doses of antipsychotic drugs and strategies for minimizing the side effects that might contribute to patients stopping their medication. A study finds that almost 40 percent of people with first-episode psychosis in community mental health clinics across the country might benefit from medication treatment changes. Psychosis is a mental disorder in which thoughts and emotions ...

Cancer from asbestos caused by more than one cell mutation

2014-12-04
It has been a long held belief that tumors arising from exposure to asbestos are caused by mutations in one cell, which then produces multiple clones. This hypothesis is challenged by new research published in the open access Journal of Translational Medicine, which suggests it is caused by mutations in multiple cells. Malignant mesothelioma is a rare form of cancer that affects the mesothelium - the protective lining that covers the internal organs, such as the lungs, the heart and the abdominal cavity. It is estimated that malignant mesothelioma affects up to 3,200 ...

No link found between bladder cancer and use of pioglitazone or rosiglitazone, Avandia

2014-12-04
Some previous studies have linked the diabetes medication pioglitazone to bladder cancer. However a new study − including more than one million people in six populations worldwide − has found no link between either pioglitazone or rosiglitazone (also known as Avandia) and bladder cancer. The new study is published in Diabetologia (the journal of the European Association for the Study of Diabetes), and is by Dr Samira Bell, Professor Helen Colhoun and Mr Danny Levin, University of Dundee, UK, and colleagues from the International Diabetes and Cancer Research ...

The Lancet Respiratory Medicine: Current guidelines not clear on which children most at risk of severe flu complications

2014-12-04
Children born prematurely are at an increased risk of flu-related complications, despite not being identified as an "at risk" group in UK, USA, or WHO guidelines, and should be a priority group for the seasonal flu vaccination, new research published in The Lancet Respiratory Medicine suggests. "Until now, guidelines highlighting groups at greater risk of developing complications from influenza, such as pneumonia, have been based on consensus opinion rather than on systematic assessment of the evidence"*, explains Dr Kay Wang from the University of Oxford in the UK. ...
