Scientists discovered that sea anemones use an immune system that works opposite to ours, yet still protects them from viruses. The finding reveals evolution created multiple successful strategies for fighting infections across the animal kingdom.
Scientists in Japan discovered a virus that rewrites its host cell's nucleus, offering fresh clues about one of evolution's biggest mysteries: how simple cells became complex life. The finding helps explain how plants, animals, and humans may have evolved their most important feature.
Scientists have confirmed that 8% of human DNA comes from ancient viruses that infected our ancestors millions of years ago. Some of those viral leftovers now perform a crucial job: helping build the placenta that makes pregnancy work.
Scientists used artificial intelligence to create a "super antigen" that could protect against entire families of viruses, not just individual strains. The breakthrough could revolutionize pandemic response by eliminating the need for new vaccines every time a virus mutates.
Researchers discovered how viruses like polio and the common cold switch on their copying machinery, revealing a promising target for new drugs that could fight multiple diseases at once. This breakthrough could lead to treatments that work against entire virus families instead of just one illness.
Researchers discovered how a vital protein acts as a "traffic controller" for our immune system and how a common virus learned to disable it. The breakthrough could lead to new treatments for autoimmune diseases by mimicking the virus's own tactics.
Researchers in Italy have developed the first promising drug to combat Zika virus, a mosquito-borne illness that can cause severe brain damage in babies. The breakthrough molecule also shows potential against dengue, yellow fever, and West Nile virus.
A single injection of an engineered virus is finally unlocking the immune system's power against glioblastoma, one of the deadliest brain cancers. Patients treated with the virus lived longer than expected, offering hope after 20 years without new treatment options.
A deadly tropical virus with up to 75% fatality rates finally has a vaccine candidate heading to human trials. Tokyo researchers modified the measles vaccine to protect against Nipah virus, which has killed dozens in recent outbreaks.
Indian health officials successfully contained a Nipah virus outbreak after swift action led to zero new infections among nearly 200 contacts. The rapid response prevented a potentially deadly spread of the virus that can kill up to 75% of those infected.
Researchers discovered a promising breakthrough linking Epstein-Barr virus to multiple sclerosis, offering hope for treating not just MS but potentially lupus, chronic fatigue, and other diseases. The findings reveal how immune cells respond to this virtually unavoidable virus that 95 percent of adults carry.
A new book argues we're missing huge opportunities by ignoring evolution's lessons for modern challenges. Understanding natural selection could revolutionize everything from medicine to decision-making.
Scientists discovered that butterflies and moths separated by millions of years use identical genes to create similar warning patterns, revealing evolution follows surprisingly predictable paths. This breakthrough could help us understand how species will adapt to future climate changes.
The largest study of ancient human DNA reveals that human evolution has dramatically accelerated since farming began, reshaping everything from disease resistance to physical appearance. Scientists found nearly 500 gene variants that changed through natural selection as our ancestors adapted to revolutionary lifestyle changes.
Cornell researchers discovered milkweed plants have evolved a brilliant new defense mechanism that could revolutionize monarch butterfly conservation efforts. The findings reveal nature's surprising innovation in one of evolution's oldest battles.
Researchers are watching one of nature's deadliest mushrooms rapidly evolve in California, revealing how species adapt to new homes. The discovery gives scientists a rare window into evolution happening right now.
A collapsed cave ceiling in Mexico created a unique laboratory where blind and sighted fish of the same species now live side by side, showing scientists how evolution works in real time. Researchers discovered key genes responsible for eye development by studying this rare natural experiment.
Scientists discovered a roadrunner-sized dinosaur in Argentina that's forcing them to rethink how some dinosaurs became miniature. The 700-gram creature proves evolution doesn't always follow a straight line.
Scientists discovered ancient fossils in volcanic ash deep inside a remote cave, uncovering clues about a forgotten chapter in evolution. The findings span a million years of preserved history.
Victoria Foe discovered that the DNA scientists dismissed as "junk" may actually be a crucial timing device that makes complex life possible. Her decades-long quest, fueled by personal loss and scientific curiosity, is rewriting what we know about evolution.
