Scientists have created the world's first monkey embryos containing human cells in an attempt to investigate how the two types of cell develop alongside each other. The embryos, which were derived from a macaque and then injected with human stem cells in the lab, were allowed to grow for 20 days before being destroyed.
It's not just social media—misinformation can spread in scientific communication too1d
When people think of misinformation, they often focus on popular and social media. But in a paper published April 12 in the Proceedings of the National Academies of Sciences, University of Washington faculty members Jevin West and Carl Bergstrom write that scientific communication—both scientific papers and news articles written about papers—also has the potential to spread misinformation.
Hungry fruit flies are extreme ultramarathon fliers, traveling up to six million times body length1d
In 2005, an ultramarathon runner ran continuously 560 kilometers (350 miles) in 80 hours, without sleeping or stopping. This distance was roughly 324,000 times the runner's body length. Yet this extreme feat pales in comparison to the relative distances that fruit flies can travel in a single flight, according to new research from Caltech.
How a molecular machine is assembled to convert light to food for plants1d
The conversion of light into chemical energy by plants and photosynthetic microorganisms is one of the most important processes in nature, removing climate-damaging CO2 from the atmosphere. Protein complexes, so-called photosystems, play the key role in this process. An international research team from Ruhr-Universität Bochum (RUB), the Max Planck Institutes of Biochemistry and Biophysics, the Cen
Self-awareness is what makes us human1d
Self-awareness — namely, our capacity to think about our thoughts — is central to how we perceive the world. Without self-awareness, education, literature, and other human endeavors would not be possible. Striving toward greater self-awareness is the spiritual goal of many religions and philosophies. The following is an excerpt from Dr. Stephen Fleming's forthcoming book Know Thyself . It is repr
First atomic model of human telomerase constructed by electron cryo-microscopy1d
Telomeres are large nucleoproteins structures that cap the ends of chromosomes in eukaryotic cells. When a cell divides, a small portion of the telomere is lost due to the inherently incomplete process of genome replication. If left unchecked, over time the telomeres will reach a critically short length and the cell will face genomic instability, deterioration or death. To offset this shortening,
Researchers create long-sought zigzag-edged carbon nanobelts1d

The Red Sea is no longer a baby ocean19h
It is 2,250 kilometers long, but only 355 kilometers wide at its widest point—on a world map, the Red Sea hardly resembles an ocean. But this is deceptive. A new, albeit still narrow, ocean basin is actually forming between Africa and the Arabian Peninsula. Exactly how young it is and whether it can really be compared with other young oceans in Earth's history has been a matter of dispute in the g

Scientists glimpse signs of a puzzling state of matter in a superconductor19h
High-temperature superconductors are famous for conducting electricity with no loss, but no one knows how they do it. Now scientists have observed the signature of an exotic state of matter called 'pair density waves' in a cuprate superconductor and confirmed that it intertwines with another exotic state — a step toward understanding how these materials work.

Climate change atlas offers a glimpse into forest futures2d
For 20 years, the USDA Forest Service's Climate Change Atlas has been giving foresters in the Eastern United States insight into how future habitat conditions may affect tree species, from dramatic change (a big increase of cedar elm, for example, and a big loss in balsam poplar) to the fairly neutral (red maple). The Forest Service scientists who designed the Climate Change Atlas recently complet

A new study by researchers from Nagoya University revealed that preoperative sarcopenia and exercise intolerance are associated with higher risks of medium-to-long-term mortality in patients with non-small-cell lung cancer.
Distinction between behaviorism and cognitivism?7h
Behviorism: all behavior can be understood to be innate behaviors that are modified by conditioning. Congitivism: the way cognitive processes (processing sensory inputs, decision making, memory) effect behavior. I don't see how these are alternative or opposed with each other. The cognitive processes listed above underpin the stimulus-response interaction that behaviorists focus their attention o
The distinction between Cognitivism and Information processing theory?7h
I have struggled to see the distinction between these terms. They are both used to describe the idea which superseded behaviorism – that the mind can be modelled essentially as a computer. Help would be appreciated! submitted by /u/GanonR [link] [comments]

Hi! We are two students of cognitive science at the University of Gothenburg in Sweden conducting a study on face-name memory as part of our Bachelor’s thesis. The study aims to investigate people’s ability to learn the names of new people. The study takes about 10-15 minutes to complete. If possible, do not use Safari for the experiment (it sometimes produces an error in Safari). Link to experim

Force transmission between cells orchestrates collective cellular motion12h
How do the billions of cells communicate in order to perform tasks? The cells exert force on their environment through movement – and in doing so, they communicate. They work as a group in order to infiltrate their environment, perform wound healing and the like. They sense the stiffness or softness of their surroundings and this helps them connect and organize their collective effort. But when th

Tarantulas: How 120-million-year-old creatures conquered the globe12h
Scary-looking tarantulas actually prefer to keep to themselves and stay in their burrows. Their sedentary nature makes a puzzle of their presence in so many places around the world. Researchers discover that this is because they've been around a very long time and rode drifting continental land masses to their contemporary positions.
