Blowing Bubbles In The Gamma-ray Sky

Good news today: the fastest horizontal flyer in the animal kingdom is now a bat.

Free-tailed bats have now been clocked flying horizontally at over 160 kilometers per hour (that’s nearly 100 mph!), toppling the previous record-holder, the swift. The record for speed of diving is still held by the peregrine falcon but we’re coming for you next, feathers.

So they found this adorable little dinosaur called Anchiornis

See those feathers? The skeleton they found was so well-preserved that scientists were able to examine the pigment cells in the feathers and compare them to those of modern day birds.

And they were able to do this with such accuracy that they know the coloration of this dinosaur. In life it looked something like this.

It just baffles me that we know the color patterns of an animal that has been dead for 161 million years

Here are 17 jaw-dropping photos of space that show us just how small we really are:

A dwarf galaxy, about 11 million light-years away from us.

These visible “loops” on the surface of the sun can reach up to 15 times the diameter of Earth in height.

FDA bans antibacterial soaps; “No scientific evidence” they’re safe, effective

Ban applies to soaps with any of 19 chemicals, including triclosan.

As Ars has reported previously, scientists have found that triclosan and other antimicrobial soaps have little benefit to consumers and may actually pose risks. These include bolstering antibiotic resistant microbes, giving opportunistic pathogens a leg up, and disrupting microbiomes. In its final ruling, issued Friday, the FDA seemed to agree. “Consumers may think antibacterial washes are more effective at preventing the spread of germs, but we have no scientific evidence that they are any better than plain soap and water,” Janet Woodcock, director of the FDA’s Center for Drug Evaluation and Research (CDER), said in a statement. “In fact, some data suggests that antibacterial ingredients may do more harm than good over the long-term.”

[…]

The ruling does not affect alcohol-based hand sanitizers or wipes, which the agency is reviewing separately. It also does not affect antiseptic products used in healthcare settings.

Asteroid Terms: Explained

There are interesting asteroid characters in our solar system, including an asteroid that has its own moon and even one that is shaped like a dog bone! Our OSIRIS-REx mission launches at 7:05 p.m. EDT today and will travel to asteroid Bennu.

Scientists chose Bennu as the target of the OSIRIS-REx mission because of its composition, size and proximity to Earth. Bennu is a rare B-type asteroid (primitive and carbon-rich), which is expected to have organic compounds and water-bearing minerals like clays.

Our OSIRIS-REx mission will travel to Bennu and bring a small sample back to Earth for study.

When talking about asteroids, there are some terms scientists use that might not be in your typical vocabulary…but we’ll help with that!

Here are a few terms you should know:

Orbital Eccentricity: This number describes the shape of an asteroid’s orbit by how elliptical it is. For asteroids in orbit around the sun, eccentricity is a number between 0 and 1, with 0 being a perfectly circular orbit and 0.99 being a highly elliptical orbit.

Inclination: The angle, in degrees, of how tilted an asteroid’s orbit is compared to another plane of reference, usually the plane of the Earth’s orbit around the sun.

Orbital Period: The number of days it takes for an asteroid to revolve once around the sun. For example, the Earth’s orbital period is 365 days.

Perihelion Distance: The distance between an asteroid and the sun when the asteroid is closest to the sun.

Aphelion Distance: The distance between the asteroid and the sun when the asteroid is farthest away from the sun.

Astronomical unit: A distance unit commonly used to describe orbits of objects around the sun. The distance from the Earth to the sun is one astronomical unit, or 1 AU, equivalent to about 93 million miles or 150 million kilometers.

Diameter: A measure of the size of an asteroid. It is the length of a line from a point on the surface, through the center of the asteroid, extending out to the opposite surface. Irregularly shaped asteroids may have different diameters depending on which direction they are measured.

Rotation Period: The time it takes for an asteroid to complete one revolution around its axis of rotation. For example, the rotation period of the Earth is approximately 24 hours, or 1 day.

Spectral Type: The classification of an asteroid, based on a measurement of the light reflected by the asteroid.

Why we need GMOs to survive climate change

Genetically modified organisms get a bad rap for many reasons, but we’ve actually been genetically altering what we eat since the dawn of human history.

“For 10,000 years, we have altered the genetic makeup of our crops,”explains UC Davis plant pathology professor Pamela Ronald.

“Today virtually everything we eat is produced from seeds that we have genetically altered in one way or another.” (You can read more about Ronald’s thoughts on genetically engineered food here.)

Right now her focus is on rice. It’s one of our basic crops and without it, we would struggle to feed much of the world.

With climate change, we’re seeing an increase in flooding in places like India and Bangladesh, which makes it harder to grow this important food staple.

So Ronald and her lab have developed a flood-tolerant strain of rice. It’s known as Sub1a or “scuba rice” and millions of farmers in South Asia are now growing it in their fields. 

Today is National Food Day, a day dedicated to hunger awareness. But as we focus on food insecurity, we need to talk more about how global warming will make the problem worse.

As our climate continues to heat up, it has huge impacts on what foods we are able to grow. Will our crops be able to survive droughts and floods? The University of California leads six labs that are working to develop other climate-resilient crops including chickpea, cowpea and millet.
