For The Better

The crystal structure of a human endogenous reverse transcriptase has similarities to HIV reverse transcriptase, a well-known tractable drug target, which will help design drugs to treat cancer and other diseases, according to a study co-authored by a …

Biofuel scientists used an oddball molecule made by bacteria to develop a new class of sustainable biofuels powerful enough to launch rockets. The candidate molecules have greater projected energy density than any petroleum product, including the leadi…

Researchers have discovered potential new drugs that target mitochondria in cancer cells. Their study in the journal Leukemia describes the compounds’ potential for killing leukemia cells when administered by themselves or in combination with other che…

An unusual ultra-faint dwarf galaxy has been discovered on the outer fringes of the Andromeda Galaxy thanks to the sharp eyes of an amateur astronomer. Follow-up by professional astronomers revealed that the dwarf galaxy — Pegasus V — contains very f…

An important gene in maize called HPC1 modulates certain chemical processes that contribute to flowering time, and has its origins in ‘teosinte mexicana,’ a precursor to modern-day corn that grows wild in the highlands of Mexico. The findings provide i…

The 2021 Dixie Fire burned over nearly 1 million acres in California and cost $637 million to suppress, making it the largest and most expensive wildfire to contain in state history. Fire history largely determined how severely the wildfire burned, and…

New research using computer simulations and Hollywood-style motion capture shows how birds optimize their landing maneuvers for an accurate descent.

Researchers have discovered that a signaling molecule called SCUBE3 potently stimulates hair growth and may offer a therapeutic treatment for androgenetic alopecia, a common form of hair loss in both women and men.

Why do two-thirds of in vitro fertilization (IVF) embryos go into developmental arrest? A new study shows that many embryos stored for IVF undergo characteristic genetic and metabolic changes that inhibit development. These results help explain the los…

Researchers have created artificial Hox genes — which plan and direct where cells go to develop tissues or organs — using new synthetic DNA technology and genomic engineering in stem cells. Their findings confirm how clusters of Hox genes help cells …

Researchers have developed a small, soft, flexible implant that relieves pain on demand and without the use of drugs. The first-of-its-kind device could provide a much-needed alternative to opioids and other highly addictive medications. It works by so…
