The colorful Clownfish lives longer than 20 years in the aquarium. Researchers of the Scuola Normale Superiore in Pisa, Italy, in collaboration with the Leibniz Institute on Aging (FLI) in Jena, Germany, have investigated the genetics behind the longevity of clownfish. By sequencing the genome and comparing the sequences with other species, they were able to show, that the secret of this longevity lies in the mitochondria and lysosomes of the clownfish. Because it is uncomplicated to keep and breed clownfish, they represent an interesting new animal model for research on longevity. The results are now published in the journal BMC Evolutionary Biology.

Clownfish, famous because of the Disney movie “Finding Nemo,” are a bright orange-white-black colored fish with three vertical stripes, which occur in the western Pacific and Indian Oceans. Clownfish live in symbiotic relationship with sea anemone. They are reliant on sea anemone for shelter in their natural habitat, which offer protection for the fish with its tentacles. The Clownfish’s mucus protection prevents it from being stung by the tentacles of the sea anemone. Thanks to this survival strategy, clownfish have a lower mortality rate than other fishes and can grow quite old. Until now there was not much known about the lifespan of this interesting sea dweller.

Graphene quantum dots drawn from common coal may be the basis for an effective antioxidant for people who suffer traumatic brain injuries, strokes or heart attacks.

Their ability to quench oxidative stress after such injuries is the subject of a study by scientists at Rice University, the Texas A&M Health Science Center and the McGovern Medical School at The University of Texas Health Science Center at Houston (UTHealth).

Quantum dots are semiconducting materials small enough to exhibit quantum mechanical properties that only appear at the nanoscale.

Scientists from Johns Hopkins Medicine have reported the successful creation of a special type of gel that mimics the lymph nodes in our bodies. This gel recruits and multiplies T cells just like actual lymph nodes do, so it could help in the fight against cancer and immune system disorders.

The lymph nodes are the boot camps of the immune system

There has been a great deal of interest in immunotherapy in the last few years, particuarly in using the T cells, a type of white blood cell, to hunt down cancer and destroy it. Our own immune system is quite literally living medicine, and when it works properly, it can deal with invading pathogens and cancers with ease; this is one reason why the traditional small-molecule approach to cancer has started to fall by the wayside in favor of immune approaches.

A team of Japanese researchers has—for the first time—demonstrated preserving frozen animal cells without a cryoprotectant agent (CPA), a substance that can protect biological material from freezing damage. To keep cells alive, all the conventional freezing methods needed to add a CPA, which can be potentially toxic and associated with cell damage and death. Their method only relies on ultrarapid cooling—or really fast freezing—for cells and vital biological material during freezing process. A safe freezing without CPA method would not only revolutionize how important research and medical material is stored, but greatly advance any and all research methods within those fields. The study was published in Proceedings of the National Academy of Sciences (PNAS) on April 1st, 2019.

AUSTIN, Texas — The Defense Advanced Research Projects Agency is examining ways to equip a small unit with swarming capabilities.

China’s “artificial sun” will achieve nuclear fusion by the middle of this century, one of the project leaders said Wednesday.

HL-2M Tokamak, the modified Chinese-designed “artificial sun” and a device to harness energy from fusion, will be completed this year. It is expected to increase the electricity intensity from one mega amperes to three mega amperes, an important step to achieve nuclear fusion, a spokesperson surnamed Liu with the press office of the Southwestern Institute of Physics (SWIP), affiliated with China National Nuclear Corporation, told the Global Times. An ampere is a standard measurement of electric current.

For instance, the deuterium (also known as heavy hydrogen) extracted from one liter of seawater releases the energy equivalent of burning 300 liters of gasoline in a complete fusion reaction, Liu said.

German scientists create see-through ORGANS in a step toward 3D-printed parts that could be transplanted in the human body…

Researchers in Germany have created transparent human organs using a new technology that could pave the way to print three-dimensional body parts such as kidneys for transplants.

Any night owls reading this will be familiar with the struggle of constantly trying to fit into a morning person’s world. And researchers might have finally identified the genetic typo that causes this social jetlag.

A 2017 study revealed that many people who stay up late and struggle to wake up in the morning aren’t lazy, their internal clock is simply genetically programmed to run between 2 and 2.5 hours slower than the rest of the population, thanks to a mutation in a body clock gene called CRY1.

“Carriers of the mutation have longer days than the planet gives them, so they are essentially playing catch-up for their entire lives,” said lead researcher Alina Patke from The Rockefeller University in New York.

AI-powered video technology is becoming ubiquitous, tracking our faces and bodies through stores, offices, and public spaces. In some countries the technology constitutes a powerful new layer of policing and government surveillance.

Fortunately, as some researchers from the Belgian university KU Leuven have just shown, you can often hide from an AI video system with the aid of a simple color printout.

Who said that? The researchers showed that the image they designed can hide a whole person from an AI-powered computer-vision system. They demonstrated it on a popular open-source object recognition system called YoLo(v2).
