Phys.org / Oldest known sewn hide and other artifacts from Oregon caves shed light on early clothing in harsh climates

In 1958, an amateur archaeologist named John Cowles excavated the Cougar Mountain Cave in Oregon and retained many of the artifacts found there. Upon his death in the 1980s, these items were transferred to the Favell Museum ...

Phys.org / Bacterial hitchhikers can give their hosts super strength

A Dartmouth study finds that molecular hitchhikers living within bacteria can make their hosts extra resistant to medical treatment by corralling them into tightly packed groups. The findings introduce a previously unknown ...

Dialog / Old galaxies in a young universe?

The standard cosmological model (present-day version of "Big Bang," called Lambda-CDM) gives an age of the universe close to 13.8 billion years and much younger when we explore the universe at high-redshift. The redshift ...

Phys.org / Football-sized fossil creature may have been one of the first land animals to eat plants

Life on Earth started in the oceans. Sometime around 475 million years ago, plants began making their way from the water onto the land, and it took another 100 million years for the first animals with backbones to join them. ...

Dialog / How charges invert a long-standing empirical law in glass physics

If you've ever watched a glass blower at work, you've seen a material behaving in a very special way. As it cools, the viscosity of molten glass increases steadily but gradually, allowing it to be shaped without a mold. Physicists ...

Phys.org / Experiment relies on pulsars to probe dark matter waves

Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, absorb, or reflect light. ...

Phys.org / Where did that raindrop come from? Climate model ensemble captures worldwide water isotopes over 45 years

Water is made of hydrogen and oxygen, and sometimes these atoms are slightly heavier than usual. These heavier forms are called isotopes. As water evaporates or moves through the atmosphere, the amount of these isotopes changes ...
