Scientists from the Skoltech Center for Energy Science and Technology, the Institute for Problems of Chemical Physics of RAS, and the Department of Chemistry of MSU presented solar cells based on conjugated polymers and fullerene derivatives, that demonstrated record-high radiation stability and withstand gamma radiation of >6,000 Gy raising hopes for their stable operation on the near-earth orbit during 10 years or even longer. The results of the study were published in ACS Applied Materials & Interfaces.
Researchers have developed a new technique to help doctors more quickly and accurately detect autism spectrum disorder (ASD) in children.
In a study led by the University of Waterloo, researchers characterized how children with ASD scan a person's face differently than a neuro-typical child. Based on the findings, the researchers were able to develop a technique that considers how a child with ASD gaze transitions from one part of a person's face to another.
For the first time, scientists grappling with how to improve the efficiency of CRISPR technology -- a gene-editing platform that uses an enzyme called Cas9 to precisely cut and edit specific sequences of DNA within a live cell -- have captured atomic-level, three-dimensional images of the enzyme before and after cutting the DNA.
The discovery of Tamu Massif, a gigantic volcano located about 1,000 miles east of Japan, made big news in 2013 when researchers reported it was the largest single volcano documented on earth, roughly the size of New Mexico.
New findings, reported this week in Nature Geoscience, conclude that it is a different breed of volcanic mountain than earlier thought, throwing into doubt the prior claim that it is the world's largest single volcano.
The chemistry of drip waters that form stalagmites and stalactites in caves around the world have given researchers an insight into our past climate.
In the first ever global analysis of cave drip water, an international team, led by Andy Baker at UNSW Australia and including scientists from Cardiff University, have explored how stalagmites and stalactites can show how groundwater resources have recharged in the past.
UPTON, NY--Solar energy harvested by semiconductors--materials whose electrical resistance is in between that of regular metals and insulators--can trigger surface electrochemical reactions to generate clean and sustainable fuels such as hydrogen. Highly stable and active catalysts are needed to accelerate these reactions, especially to split water molecules into oxygen and hydrogen.
The team of Toma Susi at the University of Vienna uses a state-of-the-art electron microscope, the UltraSTEM, to manipulate strongly bound materials with atomic precision. Since the instruments used are fully computerized, it is possible to show in a simulation how researchers actually use them. This allows for compelling and largely realistic presentations of the most recent research in materials science.
Mackerel sharks (Lamniformes) are a group consisting of some of the most iconic sharks we know, including the mako shark (the fastest shark in the world), the infamous great white shark and Megalodon, the biggest predatory shark that has ever roamed the world's oceans. An international team of researchers around Patrick L. Jambura from the University of Vienna found a unique feature in the teeth of these apex predators, which allowed them to trace back the origin of this group to a small benthic shark from the Middle Jurassic (165 mya).
What The Study Did:National registry data in Sweden were used in this study that assessed the risk of developing cancer in children and young adults with congenital heart disease compared with healthy people in the general population from birth to age 41.
Authors: Zacharias Mandalenakis, M.D., Ph.D., F.E.S.C., of the University of Gothenburg in Gothenburg, Sweden, is the corresponding author.

When the first full-length movie made with the advanced, three-color process of Technicolor premiered in 1935, The New York Times declared "it produced in the spectator all the excitement of standing upon a peak ... and glimpsing a strange, beautiful and unexpected new world."
Technicolor forever changed how cameras -- and people -- saw and experienced the world around them. Today, there is a new precipice - this one, offering views of a polarized world.
MORGANTOWN, W.Va.--Medications attach to the proteins in our bodies the way spacecrafts dock into the International Space Station. Describing that process in detail can reveal a lot about how the medications work--and what form new medications should take.
Researchers at West Virginia University have mapped the crystal structure of a protein that resides in our cells and determined--for the first time--how a drug latches onto it. The findings appear in Communications Chemistry, a Nature research journal.
In students' first year of university, poor diet is linked to unhealthy weight gain with males affected more than females. The research publishing July 3 in the open access journal PLOS ONE by Kayleigh Beaudry and colleagues at Brock University, Canada also suggests that sex-specific strategies and interventions could improve dietary habits during the move to university.
July 3, 2019--(BRONX, NY)--In a study published online today in Nature, researchers at Albert Einstein College of Medicine describe the first complete wiring diagram of the nervous system of an animal, the roundworm Caenorhabditis elegans, used by scientists worldwide as a model organism. The study includes adults of both sexes and reveals substantial differences between them.
Long before Lascaux paintings, humans engraved abstract motifs on stones, shells or egg shells. the earliest are 540,000 years old. For the archaeologists who discovered these objects, the question is whether they are the result of unpurposive behaviour, the simple desire of imitating nature or endowed with meaning. An unprecedented collaboration between archaeologists* and researchers in cognitive neuroimaging** from the CNRS, university of Bordeaux and CEA is providing answers to this question for the first time.
KANSAS CITY, MO - Thanks to super-resolution microscopy, scientists have now been able to unambiguously identify physical associations between human chromosomes. The findings have brought to light a new understanding to a curious observation first made more than 50 years ago.
The Stowers Institute for Medical Research scientists probed these physical connections between five of the chromosomes in the human karyotype in a report recently published online in the Journal of Cell Biology.
