Why a computer will never be truly conscious

Many advanced artificial intelligence projects say they are working toward building a conscious machine, based on the idea that brain functions merely encode and process multisensory information. The assumption goes, then, that once brain functions are properly understood, it should be possible to program them into a computer. Microsoft recently announced that it would spend US$1 billion on a project to do just that.

Quantum dots that light up TVs could be used for brain research

While many people love colorful photos of landscapes, flowers or rainbows, some biomedical researchers treasure vivid images on a much smaller scale – as tiny as one-thousandth the width of a human hair.

How the US census kickstarted America’s computing industry

The U.S. Constitution requires that a population count be conducted at the beginning of every decade.

Lithium ion Nobel Prize shows how individual brainstorms add up to world-transforming innovations

Nobel Prizes in Chemistry seem to rotate between novel compounds, revolutionary measurement techniques, and insights into how atoms can be combined to form new molecules and solids. This year, however, the Nobel Prize in Chemistry was awarded to the inventors of a device that has revolutionized how people use energy on demand – the ubiquitous lithium-ion rechargeable battery.

Why don’t more women win science Nobels?

All of the 2019 Nobel Prizes in science were awarded to men. That’s a return to business as usual, after biochemical engineer Frances Arnold won in 2018, for chemistry, and Donna Strickland received the 2018 Nobel Prize in physics.

Fast evolution explains the tiny stature of extinct ‘Hobbit’ from Flores Island

It’s not every day that scientists discover a new human species. But that’s just what happened back in 2004, when archaeologists uncovered some very well-preserved fossil remains in the Liang Bua cave on Flores Island, Indonesia. The diminutive size of this new human species, Homo floresiensis, earned it the nickname “Hobbit.”

Nobel Prize in Physics for two breakthroughs: Evidence for the Big Bang and a way to find exoplanets

Did the universe really begin with a Big Bang? And if so, is there evidence? Are there planets around other stars? Can they support life?

Discovery of how cells sense oxygen levels earns Nobel Prize

On the morning of Oct. 7, I woke up with the message from a colleague saying that “HIF got the 2019 Nobel Prize in Physiology or Medicine whoo hooo.” That’s exciting news for young researchers like me who are beginning our careers studying hypoxia, when the levels of oxygen are low in the cells.
