Germany's wolf population on the rise, new data shows
By the 2030s, every second summer over almost all of the entire Northern hemisphere will be hotter than any record-setting hot summer of the past 40 years. By 2050, virtually every summer will be hotter than anything we've experienced to date.
Living in the fallout zone from a nuclear disaster would be no worse for our health than living in London, due to its scale of pollution.
The most dramatic divergence between humans and other primates can be found in the brain. Our brains are three times larger, have many more cells, and one gene involved in the production of dopamine was highly expressed in human neocortex and striatum but absent from the neocortex of chimpanzees.

Cinnamaldehyde, an essential oil that gives cinnamon its flavor, may improve metabolic health. The ingredient induces fat cells, or adipocytes, to start burning energy through a process called thermogenesis.

Motivation, rather than habit, drives addictive behavior in the face of adverse consequences and constantly changing circumstances, new research on rats suggests. For addicts to obtain drugs, it often requires considerable ingenuity and flexibility—behavior that should not be described as habit.

Smart people have better connected brains - In intelligent persons, certain brain regions are more strongly involved in the flow of information between brain regions, while other brain regions are less engaged.

Avatar therapy 'reduces power of schizophrenia voices': Confronting an avatar on a computer screen helped patients hearing voices to cope better with hallucinations. Patients who received this therapy became less distressed and heard voices less often compared with those who had counselling instead.

Scientists at EPFL have discovered a new toxic form of Tau that forms as a result of its interaction with cell membranes. The research is published in Nature Communications and provides novel insights into possible mechanisms by which this protein moves in the brain and kills neurons.

The plague-causing bacterium may have first come to Europe with the large-scale migration of steppe nomads in the Stone Age, millennia before the first known historical epidemics. Findings also confirm plague bacteria undergoing genetic mutations related to its virulence at the time of its arrival.

Scientists created a mini biohybrid robot using algae, to travel through people in response to magnetic signals, that could one day carry drugs to specific parts of the body, minimizing side effects. What’s more, the robot—and its magnetic coat—appear to kill cancer cells.

4655 remphos Good old fungi! I knew you guys could do it! I wonder if we can isolate the genes responsible for these enzymes and maybe put them into other fungi, if that wouldn't cause other problems somehow.
476 mvea Journal reference: Khan, S., et al., Biodegradation of polyester polyurethane by Aspergillus tubingensis, Environmental Pollution (2017), Link: Highlights • Aspergillus tubingensis was isolated, identified, and found to degrade polyurethane (PU). • The SEM and ATR-FTIR results clearly showed the degradation on the surface of PU. • Esterase and lipase activities were determined in the presence of different supplements to medium. • This is the first report showing A. tubingensis capable of degrading PU. Abstract > The xenobiotic nature and lack of degradability of polymeric materials has resulted in vast levels of environmental pollution and numerous health hazards. Different strategies have been developed and still more research is being in progress to reduce the impact of these polymeric materials. This work aimed to isolate and characterize polyester polyurethane (PU) degrading fungi from the soil of a general city waste disposal site in Islamabad, Pakistan. A novel PU degrading fungus was isolated from soil and identified as Aspergillus tubingensis on the basis of colony morphology, macro- and micro-morphology, molecular and phylogenetic analyses. The PU degrading ability of the fungus was tested in three different ways in the presence of 2% glucose: (a) on SDA agar plate, (b) in liquid MSM, and (c) after burial in soil. Our results indicated that this strain of A. tubingensis was capable of degrading PU. Using scanning electron microscopy (SEM), we were able to visually confirm that the mycelium of A. tubingensis colonized the PU material, causing surface degradation and scarring. The formation or breakage of chemical bonds during the biodegradation process of PU was confirmed using Attenuated Total Reflectance Fourier Transform Infrared (ATR-FTIR) spectroscopy. The biodegradation of PU was higher when plate culture method was employed, followed by the liquid culture method and soil burial technique. Notably, after two months in liquid medium, the PU film was totally degraded into smaller pieces. Based on a comprehensive literature search, it can be stated that this is the first report showing A. tubingensis capable of degrading PU. This work provides insight into the role of A. tubingensis towards solving the dilemma of PU wastes through biodegradation.
664 BRMC888 Can the fungus be bred and used on a mass scale to break down plastics or is this not feasible? Also is the broken down plastic perfectly safe or does it still present problems?
255 7LeagueBoots Every few years another species of bacteria or fungus is found that breaks down plastics. Bacteria: - *Ideonella sakainesis* eats PET plastics 2016 - *Flavobacterium* has been known to degrade nylon since 1975 1975 2007 - unspecified marine microbes 2011 - *Enterobacter asburiae* and a *Bacillus sp.* taken from waxworm guts break down polyethylene 2014 - unspecified soil bacteria from the Frasier river area break down phthalates which are used in making some plastics - Ted talk 2012 - *Pseudomonas spp* break down LDPE - paper from 2012, but known from at least 2008 2012 - *Phanerochaete chrysosporium*, *Pseudomonas putida*, and *Sphingomonas macrogoltabidus* degrade HDPE 2013 Fungus: - *Pestalotiopsis microspora* and *Schizophyllum commune* break down PUR plastics and are edible 2011 - *Pleurotus ostreatus* breaks down oxo-biodegradable (D2W) plastic *without* pre-treatment 2014 There are a bunch more cases, but I think those references are enough to make the point that this is not a unique discovery. I very much hope some of these wind up being able to be used to break down plastics in an industrial capacity, but so far that has eluded us.
