Tiger bones? Lion bones? An almost extinct cycad? On-the-spot DNA checks at ports of entry

Mon, 20 Nov 17 00:00:50 -0800

Wildlife species are going extinct faster than humankind can reliably keep track of. Meanwhile, wildlife crime evolves quickly, with new tricks fueling a lucrative illegal global trade. As a result, customs and other port-of-entry officials confronted with unidentifiable bits of animals and plants need to make rapid decisions based on reliable information. LifeScanner LAB-IN-A-BOX, a portable DNA barcoding lab can serve as a new tool for rapid on-site species identification, adding to law enforcement's arsenal.



Ancient fish scales and vertebrate teeth share an embryonic origin

Mon, 20 Nov 17 00:00:40 -0800

Latest findings support the theory that teeth in the animal kingdom evolved from the jagged scales of ancient fish, the remnants of which can be seen today embedded in the skin of sharks and skate.



Twisted sex allows mirror-image snails to mate face-to-face, research finds

Mon, 20 Nov 17 00:03:40 -0800

A study led by the University of Nottingham has found that differently-coiled types of Japanese land snails should in fact be considered a single species, because -- against all odds - they are sometimes able to mate, a result which has implications for the classification of other snails.



The importance of biodiversity in forests could increase due to climate change

Fri, 17 Nov 17 00:04:20 -0800

Leipzig. Forests fulfil numerous important functions, and do so particularly well if they are rich in different species of trees. In addition, forest managers do not have to decide on the provision of solely one function, such as wood production or nature conservation: several services provided by forest ecosystems can be improved at the same time. These are the results of two studies led by scientists from Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv), and published in Ecology Letters.



No more deer in the headlight: Study finds large mammals do use road crossing structures

Fri, 17 Nov 17 00:07:10 -0800

A pilot study finds that large mammals are more likely to use wildlife crossing structures than move past a random location in the surrounding habitat. Animal movement also varied between crossing structures in different locations, suggesting that location might be more important than design. These findings are a first step towards a better understanding of the effectiveness of wildlife crossing structures.



Warmer water signals change for Scotland's shags

Fri, 17 Nov 17 00:08:20 -0800

An increasingly catholic diet among European shags at one of Scotland's best-studied breeding colonies has been linked to long-term climate change and may have important implications for Scotland's seabirds.



A sub-desert savanna spread across Madrid fourteen million years ago

Fri, 17 Nov 17 00:09:30 -0800

The current landscape of Madrid city and its vicinity was really different 14 million years ago. A semi-desert savanna has been inferred for the centre of the Iberian Peninsula in the middle Miocene. This ecosystem was characterised by a very arid tropical climatic regime with up to ten months of drought per year, according to a recent paper published in PLOS ONE. Scientists reached such conclusions after comparing mammal faunal with Africa and Asia ones



Study analyzes mutations in cerebrospinal fluid in lung cancer with brain metastases

Fri, 17 Nov 17 00:09:50 -0800

Researchers have explored the analysis of mutations in cerebrospinal fluid of lung cancer patients with brain metastases in a study presented at the ESMO Asia 2017 Congress. Tumor tissue from brain metastasis is difficult to obtain and therefore less invasive methods are needed to identify and monitor the presence of known actionable mutations.



eDNA tool detects invasive clams before they become a nuisance

Fri, 17 Nov 17 00:11:10 -0800

When seeking a cure for a disease, early detection is often the key. The same is true for eliminating invasive species. Identifying their presence in a lake before they are abundant is vital. A recent University of Illinois study successfully used environmental DNA to detect invasive clams in California and Nevada lakes. Researchers believe this tool can help identify pests before they become a problem.



Micro-spectroscopy opens new routes for diagnostics
In recent years, optics and photonics, and in particular the microspectroscopic techniques, have demonstrated their effectiveness for the materials analysis. The work 'Non-contact mechanical and chemical analysis of single living cells by micro-spectroscopic techniques' which will appear in the journal
