Cold Temp Exposure Causes Epigenetic Changes in Fat Cells
Americans waste 150,000 tons of food each day – equal to a pound per person. USDA research shows people with healthy diets rich in fruit and vegetables are the most wasteful.
Researchers found that simply being told that a performer is a professional or a student changes the way the brain responds to music. They also found that overcoming this bias took a deliberate effort.
Superionic ice has been created in the lab for the first time. The ultra-conductive version of ice, which accounts for 60% of Uranus and Neptune, was formed by compressing ice to 25,000 times the atmospheric pressure felt at sea level. The resulting ice was sixty times denser than regular water.
New microscope creates 3D movies of cells in living organisms. "It's like Star Trek" say Harvard researchers.

Mars' tiny moons (Phobos and Deimos) formed after proto-Mars collided with a dwarf-planet-sized object, finds new study.
Male fruit flies enjoy ejaculation. Fly brains showed increased signs of a rewarding experience after ejaculating, even with no females present.
Strong carbon fiber artificial muscles can lift 12,600 times their own weight - The new muscles are made from carbon fiber-reinforced siloxane rubber and have coiled geometry, supporting up to 60 MPa of mechanical stress, providing tensile strokes higher than 25% and specific work of up to 758 J/kg.
In an example of recent human evolution, scientists find free divers from Southeast Asia evolved bigger spleens, thought to give them greater endurance when holding their breaths.
Marijuana's effects on young brains diminish 72 hours after use, research says. Findings could be an indication that some of the negative cognitive effects found in previous studies may be due to the residual effects of cannabis or potentially from withdrawal effects in heavy cannabis users.
A new imaging technique called Adaptive Optical Lattice Light-Sheet Microscopy has captured cellular dynamics in living organisms with unprecedented detail.
'Exploding Ant' Rips Itself Apart To Protect Its Own
Machine Learning algorithm can predict evolution of chaotic models without knowing the equations. This may improve weather prediction some day.
Drowning caused 80% of deaths from Hurricane Harvey. Study finds 78% of those deaths occurred outside zones designated as being at higher risk for flooding. US authorities outline floodplains for 100 and 500 year floods that had a 1% and 0.2% probability respectively of occurring in any given year.
Fluorescent silk can kill harmful bacteria as biomedical and environmental remedy
Using human stem cells, researchers create 3-D model of the brain to study a mutation tied to schizophrenia, bipolar disorder, and depression

Enlarged spleen key to diving endurance of ‘sea nomads’
New Study Says Ancient Humans Hunted Big Mammals To Extinction
Researchers who found that /r/depression helped redditors improve their emotional state released a new study on long-term effects. They found that members of reddit's mental health communities faced communication challenges, but the subreddits helped them advance their writing.
Persistent Borrelia Infection in Patients with Ongoing Symptoms of Lyme Disease
'Mono' virus linked to 7 serious diseases, including lupus, multiple sclerosis, arthritis, inflammatory bowel disease, celiac disease, and type 1 diabetes. Combined, these diseases affect nearly 8 million people in the U.S.
A new study has confirmed that Hans Asperger, the Austrian pediatrician for whom a form of autism is named, collaborated with the Nazis and actively assisted in the killing of disabled children
Religiosity is generally tied to reduced suicide risk, but the opposite may be true for LGBT adults. Faith-based partners in suicide prevention and intervention services “should be willing and equipped to assist all people who seek their services, regardless of sexual orientation,” the authors write
This new microscope makes movies from inside living cells (paper sourced in article)
When threatened by other insects, minor workers ants of species Colobopsis explodens can actively rupture their body wall. Apart from leading to the ants' imminent death, the "explosion" releases a sticky, toxic liquid from their enlarged glands, in order to either kill or hold off the enemy.
A randomized trial shows the critical impact of a face-to-face doctor visit for patient perception of compassion, communication, professionalism.
Scientists (EPFL) have examined a slice from a meteorite that contains large diamonds formed at high pressure. The study shows that the parent body from which the meteorite came was a planetary embryo of a size between Mercury to Mars. The discovery is published in Nature Communications.
81 iloveworms Just heard an interview with one of the doctors behind this on BBC London. Amazing work. He said it will be a inexpensive procedure because they can make 1000s of cells from a single embryo and also the shear number of patients.
151 Filthy_Fil Why in the world would you define the abbreviation hESC and never use it again and also abbreviate RPE without giving a definition?
17 AnfarwolColo I have keratoconus does anyone know if this would help me ?
5 daithibreathnach Would this work on someone who has a macular scar due to toxoplasmosis?
6 Kronnic I work in this area and have derived Retinal Pigmented Epithelium cells from stem cells myself (but I use reprogrammed adult cells, induced pluripotent stem cells, and I use them to study the molecular biology of their degeneration) it's pretty cool to think that the type of cells I make can be used in such a way, which makes them much better to study than the cell lines I used to use.

3 ActuallyNot > We report [...] a visual acuity gain of 29 and 21 letters in the two patients, respectively, over 12 months. Does anyone know what that means?
3 WuDisciple1990 I’d love to be treated for Crohn’s disease using stem cells.
3 mortiousprime I have a friend that Macular Degeneration began with him at 13. Is there anyone to contact about him getting into trials like this?

3 WhatImAGirl Does anyone know what about the process necessitates hESC's vs induced pluripotent stem cells? I thought iPSC's were sort of the new standard for creating human tissue. Is it more expensive to create the iPSC's? Or would the cells created also be diseased if they were made from the individual's cells (and therefore with their diseased DNA)? Could they make iPSC's from a family member?
