TORONTO, Aug. 30, 2016--People who have received organ transplants are at higher risk of developing and dying of cancer than the general population. Yet a new study has found cancer screening guidelines for this group are inconsistent as is the use of these guidelines.

First-ever demographic study confirms forest elephants among the world's slowest reproducing mammals, spelling trouble for populations threatened by poaching Elephant populations will take nearly a century to recover from poaching since 2002 Closing domestic ivory markets will be debated at upcoming IUCN World Conservation Congress and CITES meeting Forest elephants are one of two species of African elephants
ITHACA, NY-- Tomatoes are already an ideal model species for plant research, but scientists at the Boyce Thompson Institute (BTI) just made them even more useful by cutting the time required to modify their genes by six weeks.
PROVIDENCE, R.I. [Brown University] -- Structural biologists show in a new study that an apparently key step in the process of cell division depends on a unique interaction among specific proteins, including one that is strongly linked to cancer. Their hope now is that the detailed new characterization of the interaction will make it a target for exploring a new cancer therapy.
Australia is known as a country full of deadly creatures - now people have trapdoor spiders hiding in their backyards.
The mysteriously elusive creatures are hiding in most forests in Brisbane and are tucked away in national parks throughout the state of Queensland, Australia.
PhD student Jeremy Wilson recently returned from a mission with the Queensland Museum to collect new specimens for its upcoming Wild State display, while also uncovering species of golden trapdoor spiders in common or remote parts of the state from Fraser Island to Cape York.
The job of policing the microenvironment around our cells is carried out by macrophages. Macrophages are the 'guards' that patrol most tissues of the body - poised to engulf infections or destroy and repair damaged tissue.
Nagoya, Japan - Kaho Maeda, Dr. Hideto Ito, Professor Kenichiro Itami of the JST-ERATO Itami Molecular Nanocarbon Project and the Institute of Transformative Bio-Molecules (ITbM) of Nagoya University, and their colleagues have reported in the Journal of the American Chemical Society, on the development of a new and simple strategy, "helix-to-tube" to synthesize covalent organic nanotubes.
Most natural ecosystems are heavily affected by changes to the human habitat, climate change or invasive species. In order to protect these ecosystems, one needs to know which organisms live in them. Therefore, assessing the state of and change in biodiversity is central to ecology and conservation biology. However, classical methods are often only suitable for determining a subset of organisms. Moreover, they are expensive and involve collecting the organisms themselves.
Cancer often results in weight loss due to unwanted metabolic complications. This so-called cancer cachexia is accompanied by a poor prognosis with regard to disease progression, quality of life, and mortality. After sepsis, cachexia is the most frequent cause of death in cancer patients. It is not entirely clear which biochemical mechanisms play a role. To date there have also not been any pharmacological possibilities for selectively influencing tumor-associated wasting syndrome.

The Editor-in-Chief for Family Medicine and Community Health, Professor Wei Wang and publisher of Planetary Health Weekly, Dr David Zuckus coordinated the July 2016 special issue focusing on the global reach of primary care and community health services.
A senior fellow at the Faculty of Chemistry, MSU, Vladimir Bochenkov together with his colleagues from Denmark succeeded in deciphering the mechanism of interaction of silver nanoparticles with the cells of the immune system. The study is published in the journal Nature Communications.
Having built their nest over the vertical ventilation pipe of an old nuclear weapon bunker in Poland, every year a large number of wood ants fall down the pipe to never return back to their colony.
This press release accompanies a presentation at the ESC Congress 2016. Edited by the ESC from material supplied by the investigators themselves, this press release does not necessarily reflect the opinion of the European Society of Cardiology. The content of the press release has been approved by the presenter.
A study published in the journal Scientific Reports from Nature publishing group, describes the mechanism by which caffeine counteracts age-related cognitive deficits in animals.
Every year, millions of people are treated for cystitis, but despite its prevalence, the disease is still a scientific mystery. Now a research team from University of Southern Denmark has succeeded in identifying how the bacteria responsible for the disease cause the disease to develop. This is a cause for optimism that more effective treatment methods can be developed.
