Physics tells us that a hammer and a feather, dropped in a vacuum, will fall at the same rate – as famously demonstrated by an Apollo 15 astronaut on the Moon. Now, CERN scientists are preparing to put a spooky new spin on that experiment, by dropping antimatter in a vacuum chamber to see if gravity affects it the same way it does matter – or if antimatter falls upwards instead.
Rutgers scientists have created a tiny, biodegradable scaffold to transplant stem cells and deliver drugs, which may help treat Alzheimer’s and Parkinson’s diseases, aging brain degeneration, spinal cord injuries and traumatic brain injuries.
Stem cell transplantation, which shows promise as a treatment for central nervous system diseases, has been hampered by low cell survival rates, incomplete differentiation of cells and limited growth of neural connections.
So, Rutgers scientists designed bio-scaffolds that mimic natural tissue and got good results in test tubes and mice, according to a study in Nature Communications. These nano-size scaffolds hold promise for advanced stem cell transplantation and neural tissue engineering. Stem cell therapy leads to stem cells becoming neurons and can restore neural circuits.
What was it like to see, up close, the H-IIA rocket (that carried Diwata-2) leave the grounds of Japan’s Tanegashima Space Center last October 29? Here’s a firsthand account from BusinessMirror.
WHILE waiting for the launching of Diwata-2 at the view deck in Tanegashima Space Center in Kagoshima, Japan, with our cameras trained at the launch site, Dr. Joel Marciano, the head of Philippine Scientific Earth Observation Microsatellite Program (PHL-Microsat) whispered: “Don’t just look at the rising rocket [named H-IIA F40 that carries Diwata-2] through your camera. Look at the real event so you can feel it.”
I didn’t know and did not have the time to ask what he meant by “feel it.”
But as the countdown started and the rocket began rising into the sky with Diwata-2 on it, I began to understand what Dr. Marciano meant.

What if we could bottle solar energy so it could be used to power our homes and factories even when the sun doesn’t shine?
Scientists have spent decades looking for a way do just that, and now researchers in Sweden are reporting significant progress. They’ve developed a specialized fluid that absorbs a bit of sunlight’s energy, holds it for months or even years and then releases it when needed. If this so-called solar thermal fuel can be perfected, it might drive another nail in the coffin of fossil fuels — and help solve our global-warming crisis.
Unlike oil, coal and natural gas, solar thermal fuels are reusable and environmentally friendly. They release energy without spewing carbon dioxide and other greenhouse gases into the atmosphere.
Russia has continued the expansion of its GLONASS constellation with the Saturday, Nov. 3, 2018 launch of a Soyuz 2.1b rocket from the Plesetsk Cosmodrome located in northern Russia.
The GLONASS-M (GLONASS-M No. 757) spacecraft that was sent aloft will now become part of Russia’s Global Navigation Satellite System (GLONASS). The rocket and its payload took to the late evening’s skies at 11:17 p.m. Moscow time (20:17 GMT / 3:17 p.m. EST) from Plesetsk’s Pad 4 at Site 43.
