Mae Jemison: The First Black Woman in Space | NASA's STS-47 Mission

🚀 34 years ago today, Mae Jemison changed the history of human spaceflight.

On September 12, 1992, NASA astronaut Mae Jemison launched aboard Space Shuttle Endeavour and became the first Black woman to travel into space.

As a mission specialist on STS-47, Jemison helped conduct 44 scientific experiments during a nearly eight-day mission involving NASA and Japan's space agency.

But her journey was about more than reaching orbit. It represented another step toward a more diverse generation of scientists, engineers and astronauts—and showed that the people who explore space can come from many different backgrounds.

From physician and engineer to NASA astronaut, Jemison's career continues to connect science, exploration and inspiration. 🌍🚀

September 12, 1992 — a date that remains part of space history.

🐦🐘 What if AI could help humans understand what animals are saying?

Artificial intelligence is becoming increasingly capable of analyzing animal sounds and identifying patterns that humans may struggle to detect.

But there is a fascinating ethical problem hiding behind that possibility: do animals have a right to privacy?

Researchers warn that decoding animal vocalizations and movements could potentially expose information animals never intended to share with humans. And if AI can reproduce those calls, the technology could potentially be used to influence animal behavior.

One example is “playback” technology, in which recorded animal calls are broadcast into the wild. Scientists say it can help study animal behavior, but it could also cause stress, disrupt social relationships or potentially be misused.

Meanwhile, a $10 million prize is encouraging researchers to develop technology capable of communicating with an animal without the animal knowing it is communicating with humans.

Could humans really “talk” with animals by the end of this decade?

And if we can… should we?

AI Could Decode Animal Communication, Raising New Questions About Privacy and Consent

AI is helping decode animal communication, but researchers warn that understanding animal signals could raise new questions about privacy, consent and exploitation.

🧬 Could damaged nerves caused by diabetes actually be repaired?

(The information in this article is strictly for general educational and informational purposes and is not a substitute for professional medical advice, diagnosis, or consultation with a doctor.)

Scientists at UTHealth Houston have reported promising results from an experimental antibody treatment designed to block MMP-9, an enzyme linked to diabetic peripheral neuropathy.

In diabetic mice, the targeted antibodies helped regenerate nerve fibers, improve wound healing and reduce degeneration of small nerve fibers. The researchers also reported improved nerve mitochondrial function and increased blood-vessel formation in the skin.

The research included models of both type 1 and type 2 diabetes.

But there is an important limitation: this is still mouse research. The treatment has not yet been established as a therapy for people.

The findings could nevertheless point toward a different strategy for diabetic neuropathy — one aimed at the underlying biological processes contributing to nerve damage rather than simply treating symptoms.

🔬 The next question is whether this approach can eventually be translated safely to human patients.

Live: SpaceX Falcon 9 rocket launches secretive U.S. Space Force mission from California

Watch live coverage as SpaceX launches a Falcon 9 rocket from California carrying a classified payload for the U.S. Space Force. Liftoff from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base is scheduled for Thursday, Sept. 10, during a launch window that opens at 8:37 a.m. PDT (11:37 a.m. EDT / 1537 UTC).

The first-stage booster, serial number B1081, launching for a 27th time, will land on the drone ship 'Of Course I Still Love You' nearly 8.5 minutes into the flight.

The USSF-153 mission will take a south-easterly trajectory upon departure from Vandenberg.

Live commentary from Spaceflight Now's Will Robinson-Smith will be provided starting about 30 minutes prior to launch.

Xylitol & Heart Risk?
A common sugar substitute found in sugar-free chewing gum, foods, drinks and toothpaste is raising new questions about heart health.

A study involving 17,710 people found that participants with the highest blood levels of xylitol had a 57% higher associated risk of major cardiovascular events over six years in one cohort. A second cohort followed for 30 years showed an 18% higher associated risk.

But there is an important distinction: the study does NOT prove that xylitol causes heart attacks or strokes.

Researchers say the findings are observational and that more research is needed to determine whether there is a direct cause-and-effect relationship.

So what does the research actually mean for people who use sugar-free products?

Read the full story for the numbers, the science and what researchers say should happen next.
