Synesthesia isn’t just in your head. The body reacts as if the colors were real.
Some people think that numbers always have a certain color. For example, the number 5 appears red. A new study reveals that their eyes respond as if they were seeing those colors in the real world. The study found that people with synesthesia, a neurological condition in which sensations mix, don’t just experience these colors […]
Live Science Today: A jaw-dropping first glimpse of the birth of a sperm whale and how NASA uses astronauts as test subjects
Today’s top news The first footage of its kind shows a sperm whale pulling its newborn calf out of the water.

This is the first time this type of phenomenon has been confirmed […]
‘A major disruption in Neanderthal history’: 65,000 years ago, all but one lineage of European Neanderthals became extinct
Neanderthals experienced a cataclysm before going extinct, resulting in only one genetic lineage surviving in Europe and then spreading across the continent, a new study shows. The findings, published March 23 in the journal PNAS, may shed light on what ultimately led to Neanderthals’ demise. Neanderthals are one of the closest relatives of modern humans […]
Astronauts ‘definitely will be test subjects’: NASA’s moon program raises big questions and big risks
Mars is out. And next time I might go to stay there. On Tuesday (March 24), NASA Administrator Jared Isaacman announced new plans to establish a “sustainable human presence” on the moon with a permanent lunar base. Isaacman said construction of humanity’s new home away from Earth could begin as early as 2027. The announcement […]
Two Neanderthals who lived in the same Siberian cave 10,000 years apart were distant relatives, found in 110,000-year-old bones
A small 110,000-year-old bone fragment from Siberia’s Altai Mountains reveals that two Neanderthals, who lived in the same cave 10,000 years apart, were distant relatives. The fragment also produced the fourth complete Neanderthal genome to date, revealing just how small and isolated Neanderthals were long before they disappeared around 40,000 years ago. Researchers discovered bone […]

(Image credit: Mauricio Anton) The discovery of a mysterious 18-million-year-old ape fossil in Egypt suggests that the ancestors of all modern apes, including humans, may have originated in northeast Africa or Arabia, a new study has found. Scientists have long believed that modern apes originated in East […]
Astronauts may have a hard time reproducing in outer space, research suggests, but what does that mean for the future of space colonies?
Zero gravity means zero game when it comes to fertilization success, new research suggests. Scientists observed sperm and eggs in a simulated microgravity environment and found that the environment hinders sperm migration, fertilization, and embryo development, posing serious challenges to the future of space colonization. The human, mouse, and pig study, published Thursday (March 26) […]
Mouse research suggests that brain aging is caused by a loss of control over how genes are regulated.
As we age, epigenetic markers that control gene expression in the brain can be ‘erased’, which can snowball and cause unintended consequences, a new mouse study suggests. Small chemical messages attached to our genetic code, called epigenetic markers, change with age in many organs of the human body, leading to the development of “aging clocks” […]

Research reveals Roman mosaic depicts topless woman fighting leopard in arena
For the first time, a Roman woman is seen fighting beasts in an arena. Ancient texts say some women fought beasts in the arenas of the Roman Empire, but a new study published March 22 in the International Journal of Sports History provides the first visual evidence that this actually happened. Women who fought beasts […]
