The future of data storage lies in DNA microcapsules      (via sciencedaily.com)     Original source 

Storing data in DNA sounds like science fiction, yet it lies in the near future. Experts expect the first DNA data center to be up and running within five to ten years. Data won't be stored as zeros and ones in a hard drive but in the base pairs that make up DNA: AT and CG. Such a data center would take the form of a lab, many times smaller than the ones today.

'Gluing' soft materials without glue      (via sciencedaily.com)     Original source 

If you're a fan of arts and crafts, you're likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers now have a brand-new way to weld squishy stuff together without the need for glue at all. They've demonstrated a universal, 'electroadhesion' technique that can adhere soft materials to each other just by running electricity through them.

Self-folding origami machines powered by chemical reaction      (via sciencedaily.com)     Original source 

Scientists have harnessed chemical reactions to make microscale origami machines self-fold -- freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.

Previously unknown intercellular electricity may power biology      (via sciencedaily.com)     Original source 

Researchers have discovered that the electrical fields and activity that exist through a cell's membrane also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. Their foundational discovery could change the way researchers think about biological chemistry. It could also provide a clue as to how the first life on Earth harnessed the energy needed to arise.

Highly dexterous robot hand can operate in the dark -- just like us      (via sciencedaily.com)     Original source 

Researchers demonstrated a highly dexterous robot hand, one that combines an advanced sense of touch with motor learning algorithms in order to achieve a high level of dexterity. In addition, the hand worked without any external cameras -- it's immune to lighting, occlusion, or similar issues. Because the hand doesn't rely on vision to manipulate objects, it can do so in difficult lighting conditions that would confuse vision-based algorithms -- it even operates in the dark.

Speedy robo-gripper reflexively organizes cluttered spaces      (via sciencedaily.com)     Original source 

A new gripper robot grasps by reflex. Rather than start from scratch after a failed attempt, the bot adapts in the moment to reflexively roll, palm, or pinch an object to get a better hold.

Ingestible 'electroceutical' capsule stimulates hunger-regulating hormone      (via sciencedaily.com)     Original source 

Engineers have shown that by using an ingestible capsule that delivers an electrical current to the cells they can stimulate the release of the hormone ghrelin. This approach could prove useful for treating diseases that involve nausea or loss of appetite, such as anorexia or cachexia.

Jellyfish-like robots could one day clean up the world's oceans      (via sciencedaily.com)     Original source 

Roboticists have developed a jellyfish-inspired underwater robot with which they hope one day to collect waste from the bottom of the ocean. The almost noise-free prototype can trap objects underneath its body without physical contact, thereby enabling safe interactions in delicate environments such as coral reefs. Jellyfish-Bot could become an important tool for environmental remediation.

Vaccine printer could help vaccines reach more people      (via sciencedaily.com)     Original source 

Researchers have designed a tabletop-sized vaccine printer that could be scaled up to produce hundreds of vaccine doses in a day and deployed anywhere vaccines are needed. The vaccine doses are contained within microneedle patches that can be stored long-term at room temperature and applied to the skin, avoiding the need for injections.

Transforming highways for high-speed travel and energy transport      (via sciencedaily.com)     Original source 

Researchers developed a proof of concept for a superconducting highway that could transport vehicles and electricity, cooling the necessary superconductors with a pipeline of liquid hydrogen. Most magnetic levitation designs feature the superconductor inside the vehicle, which is suspended above a magnetic track. The authors decided to flip that arrangement upside down, putting the superconductor on the ground and giving each vehicle a magnet. The result is a system with multiple uses, placing it within the realm of affordability.

Versatile, high-speed, and efficient crystal actuation with photothermally resonated natural vibrations      (via sciencedaily.com)     Original source 

Mechanically responsive molecular crystals are extremely useful in soft robotics, which requires a versatile actuation technology. Crystals driven by the photothermal effect are particularly promising for achieving high-speed actuation. However, the response (bending) observed in these crystals is usually small. Now, scientists address this issue by inducing large resonated natural vibrations in anisole crystals with UV light illumination at the natural vibration frequency of the crystal.
