The Sound of a Healthy Reef
Biology » Reef, Clownfish »
Woods Hole Oceanographic Institution − A new study from the Woods Hole Oceanographic Institution (WHOI) will help researchers understand the ways that marine animal larvae use sound as a cue to settle on coral reefs. The study, published on August 23rd in the online journal Scientific Reports, has determined that sounds created by adult fish and invertebrates may not travel far enough for larvae --which hatch in open ocean--to hear them, meaning that the larvae might rely on other means to home in on a reef system.
Meteorite Impact on a Nano Scale
Space » Crystal, Materials »
Vienna University of Technology − A meteorite impacting the earth under a grazing angle of incidence can do a lot of damage; it may travel a long way, carving a trench into the ground until it finally penetrates the surface. The impact site may be vaporized, there can be large areas of molten ground. All that remains is a crater, some debris, and an extensive trail of devastation on both sides of the impact site.

Biology » Cas9, Guide »
University of Massachusetts Medical School − WORCESTER, MA - A study in The Journal of Cell Biology by scientists at the University of Massachusetts Medical School reveals important new details about the inner workings of the CRISPR-Cas9 machinery in live cells that may have implications for the development of therapeutics that use the powerful gene editing tool.
Telemedicine Could Improve Eye Exam Access for People with Diabetes
Medicine » Telemedicine, Care »
University of Michigan Health System − ANN ARBOR, Mich. -- Electronic eye exams could become popular in the U.S. among patients who see them as an easy way to visit the eye doctor. After a nationwide telemedicine diabetic screening program in England and Wales, for example, diabetic retinopathy is no longer the leading cause of blindness there. Similar e-health programs could grow stateside, where diabetic retinopathy remains the main driver of new-onset blindness. But it hasn't been known if patients would participate.
One in Two Users Click on Links from Unknown Senders
Psychology » Users, Information »
University of Erlangen-Nuremberg − Most people know that e-mails and facebook messages from unknown senders can contain dangerous links. However, many users still click on them - and Dr. Zinaida Benenson from the Chair of Computer Science 1 at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has investigated why. The results of the experiment were clear: up to 56 percent of e-mail recipients and around 40 percent of facebook users clicked on a link from an unknown sender although they knew of the risks of their computer becoming infected with a…
Researchers Unravel Process for the Formation of Rainstorms
Nature » Clouds, Aerosols »
University of Copenhagen - Niels Bohr Institute − Violent thunderstorms can often cause torrential rain, which pose a threat for both humans and the infrastructure. Until now such extreme weather phenomena have been very poorly understood. However, using advanced simulations for cloud systems, researchers also from the Niels Bohr Institute have determined how complex cloud systems build up in the atmosphere, which then interact with each other and strengthen the further build up of heavy rain and severe thunderstorms. The results are published in the scientific journal, Nature Geoscience. …
Fair Or Unfair? Facial Cues Influence How Social Exclusion Is Judged
Psychology » Moral, Alexithymia »
University of Basel − People are often excluded from social groups. As researchers from the University of Basel in Switzerland report in the Journal of Experimental Social Psychology, whether uninvolved observers find this acceptable or not may depend on the facial appearances of those excluded. The exclusion of cold and incompetent looking people is more likely to be accepted.

Amazon Forests: Biodiversity Can Help Mitigate Climate Risks
Nature » Vegetation, Amazon »
Potsdam Institute for Climate Impact Research (PIK) − "Plant trait diversity may enable the Amazon forests, the world's greatest and maybe most fascinating tropical ecosystem, to adjust to some level of climate change - certain trees dominant today could decrease and their place will be taken by others which are better suited for the new climate conditions in the future," says Boris Sakschewski from the Potsdam Institute for Climate Impact Research (PIK), lead-author of the study to be published in Nature Climate Change. Tree survival for instance depends on what the…
Calm Or Fiery? Study Says Candidate Language Should Match the Times
Psychology » Candidates, Voices »
Ohio State University − COLUMBUS, Ohio - Potential voters who see the nation as being in dire economic straits view a presidential candidate as more "presidential" when he or she uses high-intensity, emotional language, a new study suggests. But people who think the country is doing just fine think a candidate sounds more presidential when the language is more restrained.
Ode to Recall: to Remember Events in Order, We Rely on the Brain's 'Symphony'
Biology » Memories, Memory »
New York University − To remember events in the order they occur, the brain's neurons function in a coordinated way that is akin to a symphony, a team of New York University scientists has found. Their findings offer new insights into how we recall information and point to factors that may disrupt certain types of memories.

Studying mutant peptides will help to detect weaknesses in tumor cells in search for more effective drug treatments. The results have been…
Drug-dispensing Contact Lens Effectively Lowers Eye Pressure in Glaucoma Model
Medicine » Glaucoma, Eye »
Massachusetts Eye and Ear Infirmary − A contact lens designed to deliver medication gradually to the eye could improve outcomes for patients with conditions requiring treatment with eye drops, which are often imprecise and difficult to self-administer. In a study published online today in Ophthalmology, a team of researchers have shown that a novel contact lens-based system, which uses a strategically placed drug polymer film to deliver medication gradually to the eye, is at least as effective, and possibly more so, as daily latanoprost eye drops in a pre-clinical…
Vesicles That Trap Amyloid Appear to Also Contribute to Alzheimer's
Medicine » Amyloid, Alzheimer »
Medical College of Georgia at Augusta University − AUGUSTA, Ga. (Aug. 29, 2016) - Vesicles, fluid-filled sacs that brain cells make to trap amyloid, a hallmark of Alzheimer's, appear to also contribute to the disease, scientists report. Reducing the production of these vesicles, called exosomes, could help reduce the amount of amyloid and lipid that accumulates, slow disease progression and help protect cognition, scientists at the Medical College of Georgia at Augusta University report in The Journal of Neuroscience.

Alzheimer's: Nicotinic Receptors as a New Therapeutic Target
Medicine » Receptor, Tie1 »
Institut Pasteur − Several scientific studies have indicated that nicotine may be beneficial for memory function. Scientists from the Institut Pasteur and the CNRS set out to shed further light on the properties attributed to nicotine - which is known to have an adverse effect on health - by determining the precise structure of the nicotinic receptors in the hippocampus region of the brain. Using mouse models for Alzheimer's disease, they identified the β2 subunit of the nicotinic receptor as a target that, if blocked, prevents…
