Design an Invisible Cloak for Bacteria to Deliver Drugs to Tumors

Laboratory Equipment. Engineering an 'Invisible Cloak' for Bacteria to Deliver Drugs to Tumors Columbia Design scientists report that they have created a "cloaking" system that temporarily conceals healing bacteria from body immune systems. This allow them to supply drugs to tumors better and eliminate cancer cells in mice. By manipulating the germs' DNA, they programmed...

New, Possibly Arboreal Rice Rat Varieties Uncovered in Ecuador

New, possibly arboreal rice rat species discovered in Ecuador - ScienceDaily - Verve timesVisitar "In total, the expeditions to the Kutukú region in southeastern Ecuador involved 1,200 trap nights, but only one specimen of the new species Mindomys kutuku was found," claims Dr. Claudia Koch, curator of herpetology at the LIB, Gallery Koenig Bonn, describing the effort...

Nuclear Fusion: How Thrilled Should We Be?

Fusion could create more energy than any other process that could be produced on Earth. Credit: Shutterstock There has been significant excitement about recent results from the Joint European Torus (JET) facility in the UK, suggesting that the dream of nuclear fusion power is inching closer to reality. We know that fusion works-- it is the...

Individual Neurons Can Learn by Predicting Future Activity

Credit: Artur Luczak Humans have been trying to comprehend exactly how the brain works and how it obtains information for centuries. While neuroscientists now have a decent understanding of how different parts of the brain work and what their function is, numerous questions remain unanswered; therefore, a unified neuroscience theory is still missing. In recent years,...

Scientists Target Protein to Lower the Risk of Prostate Cancer Proliferation

The research study, released in the peer-reviewed journal Nature Communications, opens up...

Do We Exist in a Multiverse?

As for we presently know, there is a solitary expanding blob of spacetime speckled with trillions of galaxies - that is our Universe. If there are others, forming a multiverse, we have no riveting evidence for their existence. Theories of cosmology, quantum physics, and the very philosophy of science have some issues that could be...

AI Shows that the Sahara has Millions of Trees

A Desert Full of Life Satellite images of the Sahara desert show a dry expanse, the endless rolling dunes we know from movies. Except typical satellite images do not reveal individual trees; however, that doesn't always mean they're not there. Scientists from the University of Copenhagen and NASA trained artificial intelligence to recognize trees and have them take another...

Quantum Sensor Technology Developed by Researchers Can Look Into the Earth

Seeing beneath our feet Researchers are hoping a significant advancement in quantum sensor technology that is being refed to as an "Edison moment" has worldwide implications. A new study in Nature details one of the first practical uses of quantum sensing, a since mostly theoretical technology that combines quantum physics and the study of Earth's gravity to look below...

Astronomers Identify Remains of Long-Lost Galaxy Consumed by the Milky Way

The Gaia spacecraft discovered the remains of an ancient cosmic collision in...

Mental Speed Rarely Changes Over a Lifespan

Study reveals that the speed of cognitive information processing stays exceptionally stable over decades Mental speed-- the speed at which we can manage problems needing quick decision-making-- does not change significantly over the years. Psychologists at Heidelberg University came to this conclusion under the leadership of Dr. Mischa von Krause and Dr. Stefan Radev. They...
