Gorgeous Footage of a Camouflaged Lichen Katydid Delicately Walking Along Its Matching Branch

Posted by in category: futurism

Talented wildlife photographer David Weiller has captured absolutely gorgeous footage of a beautiful markia hystrix, better known as a lichen katydid as it delicately walked along the branch of a tree covered in the distinctive white filamentous lichen for which the graceful insect was named. The insect-focused blog Nature and Moretells has more information on these beautiful creatures.

Katydids comprise a diverse group of insects particularly well adapted to survival in rainforest because of their exceptional camouflage. Most katydids are well camouflaged with brown or leaflike green markings. The Lichen Katydid, Markia hystrix (Orthoptera – Tettigoniidae), however, has one of the most incredible camouflages of all. It resembles the pale greenish-white lichens on which it lives in rainforest treetops. Not only does the color match the lichens, but the body and legs have a bizarre assortment of spines and points that blend well with lichens, in fact, so well that this insect is extremely difficult for predator to find.

This Is the Most Powerful Robot Arm Ever Installed on a Mars Rover

Posted by in categories: robotics/AI, space

Last month, engineers at NASA’s Jet Propulsion Laboratory wrapped up the installation of the Mars 2020 rover’s 2.1-meter-long robot arm. This is the most powerful arm ever installed on a Mars rover. Even though the Mars 2020 rover shares much of its design with Curiosity, the new arm was redesigned to be able to do much more complex science, drilling into rocks to collect samples that can be stored for later recovery.

JPL is well known for developing robots that do amazing work in incredibly distant and hostile environments. The Opportunity Mars rover, to name just one example, had a 90-day planned mission but remained operational for 5,498 days in a robot unfriendly place full of dust and wild temperature swings where even the most basic maintenance or repair is utterly impossible. (Its twin rover, Spirit, operated for 2,269 days.)

To learn more about the process behind designing robotic systems that are capable of feats like these, we talked with Matt Robinson, one of the engineers who designed the Mars 2020 rover’s new robot arm.

Cancer cell’s “self eating” tactic may be its weakness

Posted by in categories: biotech/medical, education, food

Cold Spring Harbor, NY — Cancer cells use a bizarre strategy to reproduce in a tumor’s low-energy environment; they mutilate their own mitochondria! Researchers at Cold Spring Harbor Laboratory (CSHL) also know how this occurs, offering a promising new target for pancreatic cancer therapies.

Why would a cancer cell want to destroy its own functioning mitochondria? “It may seem pretty counterintuitive,” admits M.D.-Ph. D. student Brinda Alagesan, a member of Dr. David Tuveson’s lab at CSHL.

The 10:33 a.m. quake was centered in the Searles Valley, a remote area of Kern County about 100 miles north of Los Angeles, and was felt as far away as Long Beach and Las Vegas.

Ultra-small nanoprobes could be a leap forward in high-resolution human-machine interfaces

Posted by in categories: biotech/medical, cyborgs, neuroscience

Machine enhanced humans — or cyborgs as they are known in science fiction — could be one step closer to becoming a reality, thanks to new research Lieber Group at Harvard University, as well as scientists from University of Surrey and Yonsei University.

Researchers have conquered the monumental task of manufacturing scalable nanoprobe arrays small enough to record the inner workings of human cardiac cells and primary neurons.

The ability to read electrical activities from cells is the foundation of many biomedical procedures, such as brain activity mapping and neural prosthetics. Developing new tools for intracellular electrophysiology (the electric current running within cells) that push the limits of what is physically possible (spatiotemporal resolution) while reducing invasiveness could provide a deeper understanding of electrogenic cells and their networks in tissues, as well as new directions for human-machine interfaces.

An Interview with Sergey Young

Posted by in categories: biotech/medical, life extension

My colleague Nicola Bagalà recently had the opportunity to interview Sergey Young, a board member of XPRIZE and the creator of the $100m Longevity Vision Fund. As you probably know, at the end of May this year XPrize hosted a 2-day workshop to better understand the bottlenecks and opportunities of the longevity industry, and in this interview, Sergey is sharing his vision on what can — and should — be done to accelerate the development of new therapies addressing aging.
