Researchers create a remote-controlled soft robot that can transform itself to conduct targeted drug delivery against cancer cells.
Proteins are vital parts of all living organisms and perform essential tasks in our bodies. They build and repair tissues, supply components of the immune and hormone systems, regulate metabolism, and transmit signals. Researchers in Berlin and Heidelberg have now developed an intelligent neural network that can predict the functions of proteins in the human body. The team used a 'trick' to observe how the network makes it predictions. The insights gained from this research could help in the search for new targeted drugs.
Wind turbines are a critical component in the strategy for energy independence, but these massive structures are also killing bats. Now, researchers from Texas A&M University are exploring a unique passive acoustic whistle mounted on turbine blades to warn bats of the deadly turbines using a sound they can easily hear and recognize. They will present the team's research findings at the 177th ASA Meeting.
Using Magnetic Resonance Imaging (MRI), scientists have captured 3D images that show how infants' brains and skulls change shape as they move through the birth canal just before delivery. Olivier Ami of Auvergne University in Clermont Ferrand, France, and colleagues present these findings in the open access journal PLOS ONE on May 15, 2019.
Researchers have provided new insight on how two proteins help influenza A virus particles fight their way to human cells.
Circadian clocks of organisms respond to light signals during night but do not respond in daytime. The time window where circadian clocks are insensitive to light signals is referred to as the 'dead zone'. Researchers from Kanazawa University have proposed a mechanism for the daytime dead zone. They report that saturation of a single biochemical reaction in the gene regulatory network that controls circadian oscillations can create a daytime dead zone in different species.
Researchers from the Tokyo University of Science, Japan, have used CRISPR gene editing technology to make snails with shells that coil the 'wrong' way, providing insights into the fundamental basis of left-right asymmetry in animals. These findings are published in the journal Development.
Princeton researchers have discovered that Pseudomonas bacteria can detect the speed (shear rate) of flow regardless of the force. By linking the flow-detecting gene to one responsible for illumination, they have bioengineered a real-time visual speedometer: The faster the flow, the brighter the glow.
In a new study, scientists at the University of Missouri have discovered that a neuron's own electrical signal, or voltage, can indicate whether the neuron is functioning normally. If that voltage is absent, scientists say everything is 'out of whack.'
The segregation of yolk from the surrounding cytoplasm in the very early fish embryo is a key process for the development of the fish larva. To identify its underlying mechanisms, biologists at the Institute of Science and Technology Austria (IST Austria) teamed up with their colleagues from theoretical physics. The discovery: Actin dynamics in the bulk of the cell drive phase segregation in zebrafish oocytes.
