In a new study published in Nature Chemistry, UNC-Chapel Hill researcher Ronit Freeman and her colleagues describe the steps they took to manipulate DNA and proteins—essential building blocks of life—to create cells that look and act like cells from the body. This accomplishment, a first in the field, has implications for efforts in regenerative medicine, drug delivery systems, and diagnostic tools.
Imagine being able to look inside a single cancer cell and see how it communicates with its neighbors. Scientists are celebrating a new technique that lets them study the fatty contents of cancer cells, one by one.

To properly protect forests and evaluate the state of natural resources, conservation practices and environmental policies, it is important to have accurate information on an area's forest extent.
The need for sustainable and environment-friendly solutions has accelerated the global demand for green and renewable technologies. In this regard, semiconductor photocatalysts have emerged as an attractive solution, owing to their potential in mitigating pollutants and harnessing solar energy efficiently. Photocatalysts are materials that initiate chemical reactions when exposed to light.
When viewing biological samples with a microscope, the light beam is disturbed if the lens of the objective is in a different medium than the sample. For example, when looking at a watery sample with a lens surrounded by air, the light rays bend more sharply in the air around the lens than in the water.
Inside the cell nucleus, the DNA molecule is found in a densely packed DNA-protein complex known as chromatin. Here the DNA is wrapped around a core of histone proteins and densely packed to form nucleosomes. The structure of the nucleosomes determines which genes are accessible and active and therefore plays an important role in gene regulation. To respond to metabolic signals, changed environmental conditions, and developmental processes, the nucleosomes must undergo repeated dynamic...
Researchers at Karolinska Institutet have developed a web-based platform that offers an unprecedented view of the human body at the cellular level. The aim is to create an invaluable resource for researchers worldwide to increase knowledge about human health and disease. The study is published in Genome Biology.
Human trafficking in Alabama was a Class A felony, punishable by 20-years to life in prison under the previous law, but the law will take those punishments a step further.
Alphabet-owned Google said on Thursday it would consolidate teams that focus on building artificial intelligence models across its Research and DeepMind divisions in its latest push to develop its AI portfolio. Google will relocate its Responsible AI teams - which focuses on safe AI development - from Research to DeepMind so that they are closer to where AI models are built and scaled, the company said in a blog post. The move comes amid growing global concerns about AI safety and increasing...
Google is consolidating the teams that focus on building artificial intelligence (AI) models across Google Research and Google DeepMind. All this work will now be done within Google DeepMind, Sundar Pichai, CEO of Google and Alphabet, said in a note to employees posted on the company’s website Thursday (April 18). Pichai said in the note that this move will “scale our […]
Flow-through reactors packed with enzymes can produce certain chemicals in a gentle and careful way. However, their performance has so far been limited. A research team from the Helmholtz-Zentrum Hereon and RWTH Aachen University has now been able to increase the yield a thousandfold.
