An innovative tool for discovering new materials has shown promise for materials engineers. Throughout history, civilizations have been known by the tools they created and left behind. To create those tools, engineers in every era have had to access materials to accomplish their goals. In the modern era, this often led innovators to craft their own unique materials.

The research has been called a “game changer” in discovering new technologies and the materials to build those technologies.

Cancer is crafty, using a wide range of insidious tricks to ensure it can survive and spread in the body. But now researchers at Rush University and the University of California, San Diego have found a way to intervene in one of these schemes, preventing tumors from recruiting immune cells to help them grow and metastasize.

Missions like the Kepler Space Telescope and the newer Transiting Exoplanet Survey Satellite (TESS) have revealed thousands of exoplanets out there among the stars, but we know surprisingly little about them. To get up close and personal, we’re going to need extremely precise space telescopes. MIT scientists have proposed an innovative way to make sure those instruments remain calibrated and capable of peering at distant exoplanets. They suggest designers incorporate a smaller secondary satellite that can act as a “guide star” for the telescope.

Space researchers are anxious to get new super-sized telescopes in space because the equipment we have right now is only adept at finding planets and relaying basic information. Most exoplanets in the database were discovered via the transit method, which watches for dips in brightness as planets pass in front of their home stars. From this, we can often discern a planet’s size, orbit, and approximate temperature. To get detailed data about its atmosphere and composition, we need telescopes like the upcoming (and chronically delayed) James Webb Space Telescope.

Webb will offer much greater imaging prowess than Hubble because its primary mirror is larger, composed of 18 hexagonal segments with a total diameter of 6.5 meters. In the coming decades, space telescopes could reach 15 meters with as many as 100 mirror segments. Such telescopes would have a coronagraph, an instrument capable of separating the intense light of a star from the faint light of an exoplanet. If this measurement isn’t perfect, the telescope would be unable to resolve the details on a planet.

Frequently reported advances in artificial intelligence make some people curious, and others nervous. While some people picture their next smart appliance purchase being an AI robot, others wonder if an AI robot will take their job. The truth is, neither of those scenarios will be a reality anytime soon.

There’s a misunderstanding about artificial intelligence (AI), and it’s a big deal. True AI doesn’t exist yet, and it’s not a likely near future, either. Despite analysis of science fiction movies and scientific reports that claim otherwise.

People get excited when new breakthroughs in machine learning are publicized, like the CNBC interview with a robot named Sophia. Sophia’s ability to answer the interviewer’s questions and stay on point is jaw-dropping for many. The truth is, Sophia isn’t any closer to true AI than the last robot. She’s programmed to provide better responses, and her lifelike appearance makes her impressive, but even Sophia isn’t demonstrating true AI. She’s not autonomous, and can’t make her own decisions.

In the rare books collection of the Huntington Library in San Marino, California, a large tome tied with string sits in an ivory box that looks like it came from a bakery. At one point, the book belonged to Edwin Hubble, who revealed that galaxies exist beyond our own and that the universe is expanding, among other things, at nearby Mount Wilson Observatory. Between the well-worn leather cover boards, I find some of the first detailed maps of the lunar surface, illustrated and engraved in the 17^th century. As I delicately place the volume back in the box, the covers leave a light brown residue on my fingertips—a small remnant of one man’s quest to tame the moon.

The book, titled Selenographia, was created by perhaps the most innovative Polish astronomer since Copernicus. But Johannes Hevelius, as we call him in the English-speaking world, has been somewhat more forgotten among history’s great scientists. Selenographia was the first book of lunar maps and diagrams, extensively covering the moon’s various phases. More than 300 years before humans stepped onto the moon’s surface, Hevelius was documenting every crater, slope and valley that he could see with his telescope. He conducted these observations, as well as others for a comprehensive star catalog, using his own equipment in a homemade rooftop observatory.

Published in 1647, Selenographia made Hevelius a celebrity of sorts. The Italian astronomer Niccolo Zucchi even showed a copy of the book to the pope. Of course, like Copernicus before him, Hevelius believed that that the Earth orbited the sun. And according to Johannes Hevelius and His Catalog of Stars, published by Brigham Young University Press, Pope Pius IX said Selenographia “would be a book without parallel, had it not been written by a heretic.”

SCIENTISTS have made a major breakthrough which they hope could lead to a cure to HIV and AIDS.

Scientists have long known that synthetic materials—called metamaterials—can manipulate electromagnetic waves such as visible light to make them behave in ways that cannot be found in nature. That has led to breakthroughs such as super-high resolution imaging. Now, UMass Lowell is part of a research team that is taking the technology of manipulating light in a new direction.

• Scientists at the University of Brisbane may have found a simple way of detecting the early stages of cancer.
• The method is inexpensive, takes 10 minutes, and can work for all types of cancer.
• The test uses gold particles to detect cancerous DNA.

According to Nature, researchers at the University of Brisbane may have developed a simple test that’s able to detect the early stages of cancer.

Not only that but the method is inexpensive, takes a mere 10 minutes, and works for all types of cancer — and the central component used for identifying cancer cells is gold particles.

An initiative called Breakthrough Starshot wants to explore another star system using ultra-powerful laser beams and wafer-thin spaceships.

It’s a goal that sounds so fantastic, you’d be forgiven for dismissing it as science fiction. But it’s no joke, and the project’s chief engineer says millions of dollars’ worth of work is moving along without any major snags.

Starshot’s founders and collaborators include the late Stephen Hawking, Harvard University astronomer Avi Loeb, and Russian-American billionaire Yuri Milner. The concept is based on more than 80 scientific studies about interstellar travel.
