Our sense of smell changes the colors we see, show scientists

Frontiers

By Mischa Dijkstra, Frontiers science writer Crossmodal associations occur when people make unconscious but stereotypical connections between two or more senses. Here, scientists showed that associations between odors and colors can be particularly strong: powerful enough to distort our perception of colors. Our five senses bombard us with environmental input 24/7.

The medicine of the future could be artificial life forms

Science Daily: Pharmacology News

Imagine a life form that doesn't resemble any of the organisms found on the tree of life. One that has its own unique control system, and that a doctor would want to send into your body. It sounds like a science fiction movie, but according to nanoscientists, it can—and should—happen in the future.

Brain is 'rewired' during pregnancy to prepare for motherhood

Science Daily: Pharmacology News

Researchers have shown that pregnancy hormones ‘rewire’ the brain to prepare mice for motherhood. The findings show that both estrogen and progesterone act on a small population of neurons in the brain to switch on parental behavior even before offspring arrive. These adaptations resulted in stronger and more selective responses to pups.

Oldest fossil human footprints in North America confirmed

Science Daily: Pharmacology News

New research reaffirms that human footprints found in White Sands National Park, NM, date to the Last Glacial Maximum, placing humans in North America thousands of years earlier than once thought. In September 2021, scientists announced that ancient human footprints discovered in White Sands National Park were between 21,000 and 23,000 years old. This discovery pushed the known date of human presence in North America back by thousands of years and implied that early inhabitants and megafauna co

And then there were 6 -- kinds of taste, that is

Science Daily: Pharmacology News

Scholars have discovered evidence of a sixth basic taste. The tongue responds to ammonium chloride, a popular ingredient in some Scandinavian candies. The OTOP1 protein receptor, previously linked to sour taste, is activated by ammonium chloride. The ability to taste ammonium chloride may have evolved to help organisms avoid harmful substances.

Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought

Science Daily: Pharmacology News

For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aft

Scientists discover the highest energy gamma-rays ever from a pulsar

Science Daily: Pharmacology News

Scientists have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about ten trillion times the energy of visible light. This observation is hard to reconcile with the theory of the production of such pulsed gamma rays, as the international team reports.

Science Daily: Pharmacology News

A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity originally developed to understand the rotation of galaxies.
