Do aliens exist?

Harvard researcher proposes that Humanity might have received a signal from aliens that it isn’t checking, "Fast radio bursts are exceedingly bright given their short duration and origin at great distances, and we haven't identified a possible natural source with any confidence," said theorist Avi Loeb of the Harvard-Smithsonian Center for Astrophysics. "An artificial origin is worth contemplating and checking." Scientists might have found proof of alien life but misunderstood it, according to a professor at Harvard University. Strange radio waves that have been reaching Earth might actually be leakage from a huge, light-powered ship deep in space. Read more

Chemists developed Nanographene − Rhenium leaf that convert CO2 (Carbon dioxide) into fuel

Carbon dioxide (chemical formula CO2) is a colorless and odorless gas that composed of one carbon and two oxygen atoms. this gas is the main factor of climate change and earth warming. Carbon dioxide exists in Earth's atmosphere as a trace gas and derived from natural and man-made sources including volcanic, the burning of organic matter, and the respiration of aerobic organisms, burning of various fossil fuels for power generation and transport use.

Bioprinting the Cancer Microenvironment

Cancer is the name given to a collection of related diseases. In all types of cancer, some of the body’s cells begin to divide without stopping and spread into surrounding tissues. Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and divide to form new cells as the body needs them. When cells grow old or become damaged, they die, and new cells take their place. Read more

The benefits of genome architecture mapping

A genome is an organism’s complete set of DNA, including all of its genes. Each genome contains all of the information needed to build and maintain that organism. In humans, a copy of the entire genome—more than 3 billion DNA base pairs—is contained in all cells that have a nucleus. The organization of the genome in the nucleus and the interactions of genes with their regulatory elements are key features of transcriptional control and their disruption can cause disease. Here we report a genome-wide method, genome architecture mapping (GAM), Read more

Hubble Telescope images

The Hubble Space Telescope (HST) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. Although not the first space telescope, Hubble is one of the largest and most versatile, and is well known as both a vital research tool and a public relations boon for astronomy. The HST is named after the astronomer Edwin Hubble, and is one of NASA's Great Observatories, along with the Compton Gamma Ray Observatory, the Chandra X-ray Observatory, and the Spitzer Space Telescope.

Lake Carnegie

Lake Carnegie is a reservoir that is formed from a dam on the Millstone River, in the far northeastern corner of Princeton, Mercer County, New Jersey. The Delaware and Raritan Canal and its associated tow path are situated along the eastern shore of the lake. Noted businessman and philanthropist Andrew Carnegie donated money for the construction of the lake, which was donated to Princeton University. Read more

earth temperature increase per year from 1880

Each year, four international science institutions compile temperature data from thousands of stations around the world and make independent judgments about whether the year was warmer or cooler than average. “The official records vary slightly because of subtle differences in the way we analyze the data,” said Reto Ruedy, the climate scientist at NASA’s Goddard Institute for Space Studies. “But they also agree extraordinarily well.” Read more

Micrometer-sized molecular robot changes its shape in response to signal molecules

Advancement in nanoscale bioengineering has allowed for the design of biomolecular devices that act as sensors, actuators, and even logic circuits. Realization of micrometer-sized robots assembled from these components is one of the ultimate goals of bioinspired robotics. In this study, Yusuke et al construct an amoeba-like molecular robot that can express continuous shape change in response to specific signal molecules. Read more

DNA Fountain enables a robust and efficient storage architecture

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA). DNA is the macromolecule that storage all biological information in codes made up of four chemical base, Adenine (A), Guanine (G), Thymine (T), Cytosine (C).Each base is also attached to a sugar molecule and a phosphate molecule.

Growing tissue grafts on humanoid robots: A future strategy in regenerative medicine?

Over the past decade, exciting progress has been made in the development of humanoid robots. The significant potential future value of humanoids includes applications ranging from personal assistance to medicine and space exploration. In particular, musculoskeletal humanoids (such as Kenshiro and Eccerobot) were developed to interact with humans in a safer and more natural way. They aim to closely replicate the detailed anatomy of the human musculoskeletal system including muscles, tendons, and bones. Read more
