Genetically modified salmon can now be imported into the US

Genetically modified salmon can now be imported into the US

The Food and Drug Administration has ended its 2016 import alert on genetically modified salmon, pointing to its past analysis of evidence related to the fish, as well as its approval of genetically modified salmon from AquAdvantage. The import alert had resulted from Congress, which ordered the FDA to block genetically engineered salmon from entering the US until final labeling guidelines had been issued.

Who sent the plush Earth toy to the International Space Station?

Who sent the plush Earth toy to the International Space Station?

If you'd seen the plush "Earthie" toy in photos of the International Space Station, you'd know it. It's basically a spherical earth in blue and green, with blue arms, blue legs, black oval-shaped eyes, and a circular black dot mouth. It's super cute, really - but where did Earthie come from? And the most obvious question - where can I get one to love and hold forever?

Study finds eye test may spot Alzheimer’s before symptoms appear

Study finds eye test may spot Alzheimer’s before symptoms appear

A non-invasive eye test may one day be used to screen patients for Alzheimer's disease, according to a new study. The test involves looking at blood vessels in the retina, but isn't something that currently takes place as part of a normal eye test. The process is described as quick, involving 'relatively new' technology that can capture high-resolution images of the small blood vessels.

NASA reveals Moon to Mars plans for its $21bn FY2020 budget

NASA reveals Moon to Mars plans for its $21bn FY2020 budget

On March 11, the Office of Management and Budget released a proposed budget offering NASA $21 billion in funding for its 2020 fiscal year, a $500 million decrease from the final fiscal year 2019 figure. Despite the decrease, NASA Administrator Jim Bridenstine called it "one of the strongest on record for our storied agency." Ultimately, the budget represents around a 6-percent increase over the amount requested last year.

New land dinosaur’s old home now covered by ocean

New land dinosaur’s old home now covered by ocean

A new species of dinosaur was identified in research published this week. This dinosaur is called Galleonosaurus dorisae, and it's a small-bodied ornithopod. Identification of this dinosaur was focused on a set of jawbones recovered in the Southwestern region of Australia. This wallaby-sized creature was most likely living in the region that connected Australia and Antarctica before the one land mass was split into two.

New quantum circuit lets researchers listen to weakest radio signals

New quantum circuit lets researchers listen to weakest radio signals

Researchers from Delft University of Technology have created a new quantum circuit that allows them to listen to the weakest radio signals that are allowed by quantum mechanics. The team sees the circuit with potential uses in future applications like radio astronomy and medical imaging using MRI tech. The chip also will enable researchers to perform experiments that could yield new information on the interplay of quantum mechanics and gravity.

NASA’s LRO spies water molecules moving around dayside of the moon

NASA has leveraged an instrument that is aboard the Lunar Reconnaissance Orbiter called the Lyman Alpha Mapping Project or LAMP. That instrument can measure the layer of molecules that are temporality stuck to the surface of the moon, allowing it to report on changes in lunar hydration throughout a day.

NASA confirms first all-women spacewalk will take place in March

NASA confirms first all-women spacewalk will take place in March

NASA revealed earlier this week that two of its astronauts currently aboard the International Space Station will make history later this month: Anne McClain and Christina Koch will conduct a spacewalk outside the station on March 29th, something that's not uncommon on its own, but this will be the first with the entire team involved made up of women.

New research shows promise for affordable infrared cameras

New research shows promise for affordable infrared cameras

Infrared camera technology is one of the types of tech that has huge potential for beneficial uses, both in consumer-focused devices and in a number of scientific fields, yet continues to remain prohibitively expensive. That might change in the near future, thanks to a new discovery by a group of University of Chicago scientists that shows promise in reducing the costs of manufacturing.

Another wave of severe flu infections is coming warns CDC

Another wave of severe flu infections is coming warns CDC

In its most recent weekly US influenza surveillance report, the Centers for Disease Control and Prevention revealed that flu activity remains high across the nation. According to the agency, both the influenza A viruses H1N1 and H3N2, as well as influenza B viruses, are still making rounds through the population, with H3 viruses more frequently reported than H1N1.

The FDA just approved this groundbreaking antidepressant nasal spray

The FDA just approved this groundbreaking antidepressant nasal spray

The FDA has announced its approval of Spravato, a ketamine-based nasal spray that can be used with oral antidepressants as a treatment for severe depression. The drug is intended for adults who suffer from treatment-resistant depression and have been unable to find relief through other medications. However, the FDA warns that Spravato's side effects may result in some potentially "serious adverse outcomes," and as such the drug has been limited to a restricted distribution system.

These injectable nanobots can walk around inside a human body

These injectable nanobots can walk around inside a human body

Researchers have developed nanobots that can be injected using an ordinary hypodermic syringe, according to a new release. The nanobots are microscopic functioning robots with the ability to walk and withstand harsh environments. Each robot has a 70-micron length, which is about the width of a thin human hair, and a million can be produced from a single 4-inch silicon composite wafer.
