Linguists Say We Might Be Able to Communicate With Aliens If We Ever Encounter Them

If humans ever encountered extraterrestrials, would we be able to communicate with them? That was the question posed by linguists from across the country, including famed scholar Noam Chomsky, during a workshop held in Los Angeles on May 26.

Organized by a scientific nonprofit called Messaging Extraterrestrial Intelligence (METI), the one-day event entitled "Language in the Cosmos" brought together two camps that don't usually converge: linguists and space scientists. The event was held in conjunction with the National Space Society's annual International Space Development Conference, which featured the likes of theoretical physicist Freeman Dyson, Amazon CEO and Blue Origin founder Jeff Bezos, SpaceX's Tom Mueller, science fiction writer David Brin, and more.

Linguist Sheri Wells-Jensen, chair of the workshop, said in a statement that it's unlikely we'll ever come face to face with aliens or find ourselves in a "Star Trek universe where most of the aliens are humanoid and lots of them already have a 'universal translator.'" Still, scientists don't rule out the possibility of chatting with extraterrestrials via radio.

Chomsky, who's often regarded as the father of modern linguistics, was optimistic that extraterrestrial life forms—if they're out there—might observe the same “universal grammar” rules he believes serve as the foundation for all human languages. His theory of universal grammar posits that there's a genetic component to language, and the ability to acquire and comprehend language is innate. Chomsky argues that a random mutation caused early humans to make the “evolutionary jump” to language some 40,000 years ago through a process called Merge, which lets words be combined, according to New Scientist. (Not all linguists are convinced by Chomsky's theory.)

At the workshop, a presentation by Chomsky (of MIT), Ian Roberts (University of Cambridge), and Jeffrey Watumull (Oceanit) argued that "the overwhelming likelihood is that ET Universal Grammar would be also be based on Merge." They said grammar would probably not be the greatest barrier in communicating with aliens; rather, understanding their "externalization system," or whatever channel they're using to communicate, could be the greatest challenge.

Another presentation by Jeffrey Punske (Southern Illinois University) and Bridget Samuels (University of Southern California) drew a similar conclusion. Human languages have physical and biological constraints, some of which are grounded in physics, so it follows that extraterrestrial languages would be limited by the same laws of physics, the linguists said.

Douglas Vakoch, president of METI, said in a statement that these theories represent a "radical shift" for scientists working in the field, who have "scoffed at the idea of creating interstellar messages inspired by natural languages." Past radio messages sent out into space relied on math and science, in hopes that those principles are universal.

The Orionid Meteor Shower Peaks This Weekend

October is always a great month for skywatching. If you missed the Draconids, the first meteor shower of the month, don't despair: the Orionids peak this weekend. If you've ever wanted to get into skywatching, this is your chance.

The Orionids is the second of two meteor showers caused by the debris field left by the comet Halley. (The other is the Eta Aquarids, which appear in May.) The showers are named for the constellation Orion, from which they seem to originate.

The shower is expected to peak overnight from Sunday, October 21, to Monday, October 22, when you can plan to see 15 to 20 super-fast meteors per hour. The best time for viewing is between 2 a.m. and 5 a.m., when Orion appears completely above the horizon. Make a late-night picnic of the occasion, because it takes about an hour for your eyes to adjust to the darkness. Bring a blanket and a bottle of wine, lay out and take in the open skies, and let nature do the rest.

There's a chance that the Moon might interfere with the meteors' visibility, according to Space.com. Leading up to its full state on October 24, the Moon will be in a waxing gibbous phase, becoming larger and brighter in the sky as the Orionids speed past Earth. Limiting light pollution where you can—such as by avoiding city lights—will help.

If clouds interfere with your Orionids experience, don't fret. There will be another meteor shower, the Leonids, in November, and the greatest of them all in December: the Geminids.

How the Hubble Space Telescope Helped the Fight Against Breast Cancer

The beauty of scientific research is that scientists never really know where a particular development might lead. Research on Gila monster venom has led to the invention of medication that helps manage type 2 diabetes, and enzymes discovered in the hot springs of Yellowstone National Park are now widely used for DNA replication, a technique used by forensic scientists to analyze crime scenes.

The same rule of thumb applies to NASA scientists, whose work has found dozens of applications outside of space exploration—especially in medicine.

Take the Hubble Space Telescope. Launched in 1990, the Hubble has graced us with stunning, intimate photographs of our solar system. But it wasn't always that way—when the telescope was launched, the first images beamed back to earth were awfully fuzzy. The image processing techniques NASA created to solve this problem not only sharpened Hubble's photos, but also had an unexpected benefit: Making mammograms more accurate.

As NASA reports, "When applied to mammograms, software techniques developed to increase the dynamic range and spatial resolution of Hubble's initially blurry images allowed doctors to spot smaller calcifications than they could before, leading to earlier detection and treatment."

That's because the Hubble Space Telescope contains a technology called Charge-Coupled Devices, or CCDs, which are basically electron-trapping gizmos capable of digitizing beams of light. Today, CCDs allow "doctors to analyze the tissue by stereotactic biopsy, which requires a needle rather than surgery," NASA says [PDF]. Back in 1994, NASA predicted that this advancement could reduce national health care costs by approximately $1 billion every year.

And that's just one of the tools NASA has developed that's now being used to fight breast cancer. When cancer researcher Dr. Susan Love was having trouble studying breast ducts—where breast cancer often originates—she turned to research coming out of NASA's Jet Propulsion Laboratory. As Rosalie Chan reports for the Daily Beast, the Jet Propulsion Lab has dedicated vast resources to avoiding the spread of earthly contaminants in space, and its research has included the development of a genomic sequencing technology that is "clean and able to analyze microscopic levels of biomass." As Dr. Love discovered, the same technology is a fantastic way to test for cancer-linked microorganisms in breast duct tissue.

A second technology developed at NASA's Jet Propulsion Laboratory—the Quantum Well Infrared Photodetector, or QWIP—enables humans to see invisible infrared light in a spectrum of colors, helping scientists discover caves on Mars and study volcanic emissions here on Earth. But it's also useful at the doctor's office: A QWIP medical sensor can detect tiny changes in the breast's blood flow—a sign of cancer—extremely early.

And as any doctor will tell you, that's huge: The earlier cancer is detected, the greater a person's chance of survival.
