STEM News 📰
Dark energy isn't what we thought – and that may transform the cosmos
New research from the Dark Energy Spectroscopic Instrument (DESI) suggests that dark energy, which drives the universe's accelerated expansion, may be weakening over time, challenging long-held cosmological theories.
DESI's findings: Data from 15 million galaxies analyzed over three years shows dark energy may change over time, contradicting the standard cosmological model (lambda-CDM).
Dark energy's impact: It could mean the universe's expansion rate is slowing, rather than speeding up.
Statistical significance: The results reach 4.2 sigma but could hit 5 sigma within two years, solidifying the discovery.
Potential consequences: If dark energy weakens, future cosmic scenarios like the "big crunch" may become more plausible, where the universe contracts instead of expanding.
Ongoing research: Future surveys and experiments are expected to refine these findings, with the DESI data leading to new theoretical models of the universe's fate.
Stem Cell Treatment Shows Promise for Paralysis Recovery
A recent trial using reprogrammed stem cells to treat spinal cord injuries has shown promising results, offering new hope for individuals with paralysis.
Participants: Four men received neural stem cell injections derived from induced pluripotent stem (iPS) cells. The participants ranged in age, with two over 60 years old.
Treatment method: Two million neural precursor cells were injected into each participant’s injury site, aiming to regenerate neurons and glial cells.
Results: One participant regained the ability to stand and is now training to walk. Another regained movement in arms and legs but cannot stand. Two participants showed minimal improvements in movement and sensation.
Safety: No serious adverse effects were observed during the trial, and participants were given immune-suppressing drugs to prevent cell rejection for six months.
Future research: Larger trials are planned to better understand the potential of iPS cells for spinal injury recovery.
