Cracking the code to regenerate plant tissues

Can epigenetics help us grow food more efficiently and combat global hunger? Plant regeneration can occur via formation of a mass of pluripotent cells. The process of acquisition of pluripotency involves silencing of genes to remove original tissue memory and priming for activation by external input. Led by Professor Sachihiro Matsunaga from Tokyo University of

A ballistocardiogram is a non-contact way of measuring changes in the cardiovascular system

MU scientists advance a way to track changes in a person’s cardiovascular system Every heart beat sends blood flowing throughout the human body. While an electrocardiogram uses a contact approach to measure the electrical activity of the heart, a ballistocardiogram is a non-contact way of measuring the mechanical effect of the blood flow through the

A solid-state sodium-ion battery arrives

Solid-state sodium-ion batteries are far safer than conventional lithium-ion batteries, which pose a risk of fire and explosions, but their performance has been too weak to offset the safety advantages. Researchers Friday reported developing an organic cathode that dramatically improves both stability and energy density. The improved performance, reported in the journal Joule, is related to

Enabling cooling without energy consumption

Physicists at the University of Zurich have developed an amazingly simple device that allows heat to flow temporarily from a cold to a warm object without an external power supply. Intriguingly, the process initially appears to contradict the fundamental laws of physics. If you put a teapot of boiling water on the kitchen table, it

Artificial intelligence could speed the development of safe, clean and virtually limitless fusion energy for generating electricity

Artificial intelligence (AI), a branch of computer science that is transforming scientific inquiry and industry, could now speed the development of safe, clean and virtually limitless fusion energy for generating electricity. A major step in this direction is under way at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University,

Refrigerators and air conditioners could run on an eco-friendly solid material instead of gases

Researchers from the UK and Spain have identified an eco-friendly solid that could replace the inefficient and polluting gases used in most refrigerators and air conditioners. Refrigeration and air conditioning currently devour a fifth of the energy produced worldwide, and demand for cooling is only going up. Xavier Moya When put under pressure, plastic crystals

Scientists are a step closer to developing artificial lymph nodes that can spark T-cells to fight disease

In a proof-of-principle study in mice, scientists at Johns Hopkins Medicine report the creation of a specialized gel that acts like a lymph node to successfully activate and multiply cancer-fighting immune system T-cells. The work puts scientists a step closer, they say, to injecting such artificial lymph nodes into people and sparking T-cells to fight

Synthetic biologists have added high-precision analog-to-digital signal processing to the genetic circuitry of living cells

Synthetic biologists add tunable, analog-to-digital converter to their toolkit Synthetic biologists have added high-precision analog-to-digital signal processing to the genetic circuitry of living cells. The research, described online today in the journal Science, dramatically expands the chemical, physical and environmental cues engineers can use to prompt programmed responses from engineered organisms. Using a biochemical process called cooperative
