Researchers are testing a technique they say could determine the age of lobsters. Lobsters can live to be more than 100 years old. Their ages are typically estimated based on size, as they shed their shells and grow larger as they get older. University of Maine research professor Rick Wahle and graduate student Carl Huntsberger say that method of estimating a lobster's age is inexact. That presents a problem for scientists and fishery managers looking to measure the health of the lobster population. Wahle and Huntsberger are testing a new method based on research by University of New Brunswick scientist Raouf Kilada. Kilada found tree-ring-like microscopic bands within lobsters' stomachs.

Malaysia's health minister said Sunday autopsy results suggested a nerve agent caused "very serious paralysis" that killed the exiled half brother of North Korea's leader, as police completed a sweep of the budget terminal where he was poisoned and declared it safe of any toxin. The investigation has unleashed a serious diplomatic fight between Malaysia and North Korea, a prime suspect in the Feb. 13 killing of Kim Jong Nam at Kuala Lumpur's airport.
Katherine Johnson, one of the NASA research mathematicians portrayed in the Oscar-nominated film "Hidden Figures," received a standing ovation at the Academy Awards on Sunday. Johnson, portrayed in the movie by Taraji P. Henson, worked for NASA as a research mathematician for more than 30 years, according to NASA's website. Appearing at the Dolby Theatre, Johnson, now 98 years old, thanked the crowd for their support. Johnson was instrumental in Alan Shepard's journey to become the first American in space and in John Glenn's mission to become the first American to orbit the Earth. She, along with the other women of color in the program, dealt with segregation in Jim Crow-era Virginia where NASA's
ABC News' Ron Claiborne learns that that a cousin was a groundbreaking figure in aeronautical engineering. One of the best movies of this year and there have been a lot of great ones, one is called "Hidden figures" up for three oscars, tells the story of three AfricanAmerican female math me tigs who played a vital role in nasa during the early years of space program. Ron, you just recently found out that this movie hits close to home for you.
You're gonna need a bigger mug of coffee. This Sunday morning, when the moon gets between Earth and the sun, enjoy breakfast with an annular solar eclipse. This eclipse's path stretches from the Pacific to the Atlantic and Africa, through Chile, Argentina, Angola, Zambia and the Congo, according to Fred Espenak, a retired NASA eclipse expert. Go online to the astronomy website Slooh.com, if you have hopes of catching this "ring of fire" cosmic event. The live stream begins at 7 a.m. ET. The "greatest duration" of the eclipse - west of Chile in the South Pacific Ocean - occurs at 8:16 a.m. ET, which lasts about 1 minute and 22 seconds, when the eclipse ribbon is 59 miles wide. The "greatest eclipse"
Sure, the scientific process itself is meant to be separated from politics, but it isn't, and can't ever be, given the implications of scientific findings and ways that politics works its way into education and research funding.
There is still a need for a 'culture change' to enable more women to work in science, according to one of the world's leading astrophysicists. Prof Jocelyn Bell Burnell was speaking at an event in Belfast Metropolitan College (BMC) to encourage more girls to study STEM subjects. The Lurgan-born scientist is credited with the discovery of radio pulsars. The breakthrough is considered one of the most significant in astronomy and physics. Speaking to the BBC at the seminar on Friday, she said: "If you look at other countries, you'll find lots of girls doing physics, engineering and science. "It's something to do with the kind of culture we have in the English-speaking world, about what's appropriate
The thorny skate's population may have declined, but not by enough to justify listing it under the Endangered Species Act, the federal government has ruled. Environmental groups had argued that the bottom-dwelling fish's population loss in the northwest Atlantic Ocean was considerable enough to afford it protections set aside for endangered animals. Documents published in the Federal Register on Friday state that the fisheries service has concluded the thorny skate is "not currently in danger of extinction" in all or a significant piece of its range.
(SOUNDBITE OF BACON SIZZLING) SCOTT SIMON, HOST: The crackle and pop of bacon frying in a pan. Or is it a meteor? Well, that last sound really was bacon. But the sizzle is how people have often described the sound they hear when meteors pass overhead. And for a long time, scientists doubted these accounts. Now, a group of researchers thinks they have an explanation for the snap, crackle and pop some people hear from meteors. Bill Sweatt of the Sandia National Laboratories joins us from Albuquerque. Thanks very much for being with us. BILL SWEATT: Happy to be here. SIMON: Now, first, is is this real or in people's minds, hearing bacon? SWEATT: It's real. There are other experiments that people
There's a big disparity when it comes to men versus women in science, technology, engineering, and math (STEM) professions. As a techie since childhood, I've always been fascinated with STEM and even earned my networking certificates before graduating high school! Coding at an early age is what got me motivated to get into a STEM profession. It's also why in college I went on to earn my Bachelor's of Science degree in information technology new media from Rochester Institute of Technology. My interest in STEM has shaped my exciting career as a tech expert and global tech consultant, and part of my personal mission is to get more girls and young women interested in STEM careers. So in honor of

The strangest place writer Mark O’Connell has ever been to is the Alcor Life Extension Foundation — where dead bodies are preserved in tanks filled with nitrogen, in case they can be revived with future technology. The nonfiction book delves into the world of transhumanists, or people who want to transcend the limits of the human body using technology. Transhumanists have been around since at least the 1980s, but have become more visible in the past decade as technology advances have made these ideas seem more feasible and less like sci-fi.
Stargazers applauded as they were plunged into darkness Sunday when the moon passed in front of the sun in a spectacular "ring of fire" eclipse. Astronomers and enthusiasts in Argentina were among the first to see the so-called annular eclipse as it crossed South America shortly after 1200 GMT, on course for Africa. Staring up through special telescopes, protective glasses or homemade cardboard pinhole devices, they watched the Sun all but disappear briefly as the Moon crossed its path.
A major seed deposit critical to ensuring global food security was made to the Svalbard Global Seed Vault in the Arctic Circle on Wednesday. Despite a backdrop of geopolitical volatility, nearly 50,000 samples of seeds from seed collections in Benin, India, Pakistan, Lebanon, Morocco, the Netherlands, the U.S, Mexico, Bosnia and Herzegovina, Belarus and the U.K have traveled to the vault on the Svalbard archipelago between mainland Norway and the North Pole on Wednesday for long-term safekeeping. The preparation and shipment of seeds to the facility has been funded in-part by the Crop Trust, the only organization working worldwide to create, fund and manage an efficient and effective global system of seed collections. The Svalbard Global Seed Vault, the world's largest collection of agricultural biodiversity, is a safe and secure vault supported by the Crop Trust which can store up to 4.5 million samples of crops from all over the world.
Major changes are coming to the ag and food sector. The market demands it. 7.5 billion people need to eat, after all. We are seeing two core areas of innovation in the ag sector: 1. Technology is changing the way growers access and disseminate information. Consider innovations like remote sensing by established player Planet Labs or startup SaraniaSat that give growers virtual “eyes in the sky,” helping them track their crops’ growth and overall health. Genomics and plant sciences, seed tech, biologicals for crop protection and regulation, digital Ag (application of data and predictive analytics to precision Ag) and novel farm systems, are also transforming agricultural practices — from the moment
As the debate over how to mitigate the most devastating impacts of climate change swirl, one potential solution remains largely ignored. Unlike calls to implement governmental programs to cut the use of fossil fuels or implement carbon taxes, this solution is one that we can all make happen every single day in the form of what we choose to put on our plates. Animal agriculture is the leading cause of global greenhouse gas emissions, the United Nations Food and Agriculture Organization (FAO) estimates that livestock production is responsible for 14.5 percent of global greenhouse gas emissions, while other organizations like the Worldwatch Institute have estimated it could be as much as 51 percent.
SAN FRANCISCO — For more than a year, mobile satellite services provider Inmarsat has been working with Addvalue Innovation (AVI), a communications technology company based in Singapore, to conduct secret tests of a service that lets operators maintain continuous contact with small satellites in low Earth orbit. Now, the companies are ready to offer the Inter-satellite Data Relay Service (IDRS) to satellite operators. "We are excited about this opportunity because strategically it opens a new market sector for us," Peter Dingley, Inmarsat vice president for future government technologies, told SpaceNews. "With just three satellites in geosynchronous orbit we can see these small satellites as
In recent years, we’ve seen an increasing number of so-called “intelligent” digital assistants being introduced on various devices. At the recent CES, both Hyundai and Toyota announced new in-car assistants. Although the technology behind these applications keeps getting better, there’s still a tendency for people to be disappointed by their capabilities — the expectation of “intelligence” is not being met. Despite great strides in natural language processing (NLP) by data-driven approaches, natural language understanding remains elusive. The Winograd Schema Challenge is a recently proposed improvement on the Turing Test for assessing whether a machine can be judged “intelligent.” It’s named
Is it really some type of liquid magnet? The typical ferrofluid you see in viral videos is made by mixing a bunch of very, very small bits of iron oxide with oil, and usually some kind of surfactant to prevent the pieces from clogging together. The most common kind of iron oxide used in ferrofluid is known as magnetite, because — you guessed it — it’s a ferromagnetic material that’s not only attracted to magnets, but that can also be magnetized and turned into a permanent magnet itself.
At the request of the new Trump Administration, NASA has initiated a month long study to determine the feasibility of converting the first integrated unmanned launch of the agency’s new Space Launch System (SLS) megarocket and Orion capsule into a crewed mission that would propel two astronauts to the Moon and back by 2019 – 50 years after the first human lunar landing. Top NASA officials outlined the details of the study at a hastily arranged media teleconference briefing on Friday, Feb 24. It will examine the feasibility of what it would take to add a crew of 2 astronauts to significantly modified maiden SLS/Orion mission hardware and whether a launch could be accomplished technically and safely by the end of 2019. On Feb. 15, Acting Administrator Robert Lightfoot announced that he had asked Bill Gerstenmaier, associate administrator for NASA’s Human Exploration and Operations Mission Directorate in Washington, to start detailed studies of what it would take to host astronauts inside the Orion capsule on what the agency calls Exploration Mission-1, or EM-1.
Sometimes cells resist medication by spitting it back out. Cancer cells, in particular, have a reputation for defiantly expelling the chemotherapy drugs meant to kill them. Researchers at The Rockefeller University have shed new light on a molecular pump that makes this possible, by determining its three-dimensional structure, down to the level of atoms. "This molecular machine ejects numerous anticancer agents, as well as other drugs. However, no one understood how it can recognize and remove such an impressive variety of substances," says lead researcher Jue Chen, the William E. Ford Professor and head of the Laboratory of Membrane Biology and Biophysics. "By examining how this drug resistant
Rising seas, polluted coastlines and the specter of more frequent droughts and storms have lent new urgency to efforts to restore the ecosystem of the Florida Everglades, the largest freshwater wetland in the United States. The Everglades' sawgrasses, swamps, tree islands and mangroves are home to a host of fascinating species, from American alligators to endangered hook-billed birds known as snail kites to invasive Burmese pythons. Until now, the world's largest ecosystem restoration project -- a massive plan expected to spend some $10.5 billion, known as the Comprehensive Everglades Restoration Plan -- has made little progress since it was launched in 2000.
During the total solar eclipse that will take place in August, scientists positioned across the U.S. will be scrambling to gather data in the 2 minutes or so that the moon covers the entire disc of the sun. Jay Pasachoff, a professor of astronomy at Williams College in Massachusetts, might be involved in more total-eclipse-related science investigations than anyone else on the planet (not even he can keep track of exactly how many, but this Space.com reporter counts at least seven). Tomorrow, he and some of his collaborators will be in southern Argentina, observing the annular solar eclipse — when about 99 percent of the sun will be covered by the moon — as a practice run for August's main event.
Michael Lemonick is as good as it gets in science journalism. He is a graceful, witty writer, who excels at telling stories that reveal science’s human dimension. He is also a meticulous reporter, who actually cares about these things called “facts.” We graduated from the same journalism school in 1983, and Mike became the go-to science writer at TIME when it was a media colossus. He reported on everything from dark matter and exoplanets to AIDS and global warming, and he wrote more than 50 cover stories. Now the opinion editor at Scientific American (for which he has also written lots of articles), Mike has authored seven books, most on astronomy and cosmology. His latest, The Perpetual Now:
