Bacteria form colonies— it’s what they do. But to do so in an organized fashion, each bacterium needs to communicate with its neighbors. UIC researcher Michael Federle is investigating techniques for jamming bacterial communication signals to prevent them from forming antibiotic-resistant biofilms. Read more

At the cellular level, a nanobeam acts like a needle able to penetrate cell walls without injury. The primary and most immediate use would be in the real-time sensing of specific proteins and biomolecules within the cells. To detect these key molecules, researchers coat the probe with certain organic molecules or antibodies that are known to attract the target proteins, just like iron to a magnet. If the desired proteins are present within the cell, they begin to accumulate on the probe and cause a slight-but-detectable shift in the wavelength of the light being emitted from the device
Imaging the interior processes of a cell, without disrupting those processes, is one of the major aims of cellular biology. Any and all new information gleaned from such imaging would be invaluable data

All of our skin organs form from simple folds in skin tissue. Once this process was in place, it was modified to produce all kinds of skin organs — from a reptile’s scale to a bird’s feather to a mammal’s mammary glands.

Chaos and the Double Pendulum
A chaotic system is one in which infinitesimal differences in the starting conditions lead to drastically different results as the system evolves.
Summarized by mathematician Edward Lorentz, ”Chaos [is] when the present determines the future, but the approximate present does not approximately determine the future.”
There’s an important distinction to make between a chaotic system and a random system. Given the starting conditions, a chaotic system is entirely deterministic. A random system, on the other hand, is entirely non-deterministic, even when the starting conditions are known. That is, with enough information, the evolution of a “chaotic” system is entirely predictable, but in a random system there’s no amount of information that would be enough to predict the system’s evolution.
The simulations above show two slightly different initial conditions for a double pendulum — an example of a chaotic system. In the left animation both pendulums begin horizontally, and in the right animation the red pendulum begins horizontally and the blue is rotated by 0.1 radians (≈ 5.73°) above the positive x-axis. In both simulations, all of the pendulums begin from rest.
Mathematica code posted here.

Researched at RIKEN Advanced Science Institute used slime mold in a classic problem solving computer science experiment - the travelling salesman problem. It’s billed as neuro computing, so it may involve an amoeba neural networkSome of the hoped for outcomes of slime mold based computing include:
Novel information processing mechanisms (of the photo-chemical-mechanical transport type)
Amoeba Inspired Algorithms
Amoeba Inspired Smart Materials
Social Systems Design
A living cellular computer[video]

Michael Joaquin Grey [1984] | Artificial Muscle Contraction
In “artificial muscle contraction” Michael Joaquin Grey takes a sample of his own muscle proteins and places them in a test tube mixture (aka ‘in vitro’) to create a simulation of contraction. The self regulating properties of the cells proteins contort the mixture into an undulating sculptural video art work (it is traditionally played as an endless loop). A stark meditation on the intricate machinery contained in one tiny element of our cellular bodies, it also articulates how crucial in-vivo & in-vitro are as biological designations. In abstracting a biological system to further comprehension a question is raised:

“What is being measured? Is it still a biological function, or has it shrunk to a chemical process?”Hans-Jörg Rheinberger

Tardigrades - Microscopic Water Bears
They may look cute but Tardigrades are one of the hardiest creatures on the planet. They are considered under a distinction of life as an extremophile, meaning they can survive in a hostile environment examples include the arctic, deserts, hydrothermal vents and more.
However Tardigrades have a gained a further fame of their own as a polyextremophile by being able to survive not only intense heat, but cold, radiation, desiccation and even the vacuum of space! It’s important to remember that we are considering extreme measured against human abilities, nevertheless these abilities make Tardigrades of great scientific interest.
What researchers believe allows Tardigrades these extreme abilities is their ability to effectively shutdown internally going into stasis and their remarkable repair mechanisms when in this state. Overall they can dehydrate themselves completely known as an anhydrobiotic state a form of Cryptobiosis and survive without a metabolism for months.
Why Tardigrades can do this might be due to how their environments have shaped them. Being less than 1mm in size exposes these organisms to a dynamic and harsh environment. Meaning they have been selected to be able to cope with sudden drastic changes such as loss of water, extreme changes in temperature, similar to the conditions of space. In fact these organisms have multiple forms of existence further refining their abilities to survive in extreme environments. Although eventually every organism needs to eat and when they do their preferred diet consists of algae perhaps filling stores to survive future conditions. Researchers have ongoing research into these creatures in Italy & NASA.

Hypsibius dujardini imaged with ascanning electron microscopeAlthough some species are parthenogenetic, both males and females are usually present, each with a single gonad located above the intestine. Two ducts run from the testis in males, opening through a single pore in front of the anus. In contrast, females have a single duct opening either just above the anus or directly into the rectum, which thus forms a cloaca.
