It does not take much to confuse some robots. A machine might be great at handling a simple object like a box, yet when it tries to work with a more irregular shape like a banana, it often fails.

Whether it's robotic rovers heading to Mars or, one day, a crew of astronauts, a round-trip journey is an incredibly long one. But there may be a way to find a shortcut. A new study published in the journal Acta Astronautica ...

Carbon nanotubes are one technology that many observers believe hasn't quite lived up to the extreme hype that surrounded them when they first appeared on the scene in the late 1990s. At that time, much was made of their ...

Scientists may have discovered another way the human body tries to protect itself from cancer. New research on mice suggests that the heart's constant beating may prevent tumor growth in cardiac tissue. Most organs are vulnerable ...

Humans are generally a cooperative bunch and most of us probably like to think of ourselves as reliable team players. Cooperation is useful for all sorts of reasons, from running a business and managing community resources ...

New York, New Orleans and Miami are among the eight cities along the US Gulf and Atlantic coasts facing the highest flood risk, according to a new study published in Science Advances. Scientists developed a new AI-driven ...

Nature is a riot of color. In the animal kingdom, many species, from insects to cephalopods, use their permanent color or change it for communication, camouflage, and thermoregulation. While this type of reversible shift ...

Mud-rich coastlines could face a greater tsunami risk, at least that may have been the case for the 2011 Tōhoku-oki tsunami that killed more than 19,000 people and led to the Fukushima Daiichi nuclear disaster. According ...

Diamond is among the hardest naturally occurring substances on Earth, but if you shrink it down to the nanoscale, it is surprisingly elastic. And that could be useful for a host of applications such as quantum computing. ...

Marburg virus disease (MVD) is a severe and often fatal hemorrhagic disease in humans caused by the Marburg virus. It is carried by Egyptian fruit bats and can spread to people after exposure in caves or mines where they ...

Archaeologists are unearthing evidence of long-term human occupation in the mountains of the Republic of Georgia. A new paper published in the journal Antiquity reports on eight years of digging on the Javakheti Plateau, ...

Spanish Renaissance master El Greco is often considered one of the greatest painters of all time, and many of his artworks are displayed in galleries around the world. His painting The Baptism of Christ is generally believed ...

While sustainable solar energy can potentially meet our global power needs, it has one major flaw. When sunlight disappears, solar panels stop generating electricity. The problem is that while they do an excellent job of ...

A paper published in the journal Science Advances is adding to the growing body of research showing that the Atlantic Meridional Overturning Circulation (AMOC) is weakening. In this new study, instead of relying mainly on ...

The physical differences between men and women are all too obvious, but the biological divide goes right down to the cellular level in the brain, according to a new study published in the journal Science.
