Researchers make sand that flows uphill

Engineering researchers have discovered that sand can actually flow uphill. A corresponding video shows what happens when torque and an attractive force is applied to each grain — the grains flow uphill, up walls, and up and down stairs.

Genetically modifying individual cells in animals

Researchers have developed a method that lets them genetically modify each cell differently in animals. This allows them to study in a single experiment what used to require many animal experiments. Using the new method, the researchers have discovered…

Strengthening artificial immune cells to fight cancer

Among available immunotherapies, the use of ‘CAR-T’ cells is proving extremely effective against certain blood cancers, but only in half of patients. A main reason for this is the premature dysfunction of these immune cells, which have been artificiall…

New method makes microcombs ten times more efficient

Microcombs can help us discover planets outside our solar system and track new diseases in our bodies. But current microcombs are inefficient and unable to reach their full potential. Now, researchers have made microcombs ten times more efficient. Thei…
