In one video, you can see a hungry caterpillar, first working around a leaf's edges, approaching the base of the leaf and, with one last bite, severing it from the rest of the plant. Within seconds, a blaze of...
A previously unknown component of our cells that delivers proteins like a bike courier in heavy traffic could shed light on the mechanisms that allow cells to spread in diseases such as cancer.
The new vesicle discovered by scientists from...
Life converts food into cells via dense networks involving thousands of reactions. New research uncovers insights as to how such networks could have arisen from scratch at life's origin. An international team of researchers in Germany, New Zealand and...
Soil is full of life, essential for nutrient cycling and carbon storage. To better understand how it functions, an international research team led by EMBL and the University of Tartu (Estonia) conducted the first global study of bacteria and...
Despite volumes of data currently available on mankind, it is surprising how little we know about other species. A paper published this week in the journal Proceedings of the National Academy of Sciences (PNAS) confirms that critical information, such as fertility...
Activating a gene called AMPK in the nervous system induces the anti-aging cellular recycling process of autophagy in both the brain and intestine. Activating AMPK in the intestine leads to increased autophagy in both the intestine and brain. Matthew...
A new study identified 81 children seen at the hospital, and 163 marijuana exposure calls to a Colorado regional poison center (RPC). The median age of children who visited the hospital was 2.4 years and 2 years for children...
DNA activity can change without changing the sequence of the DNA segment itself. Gene activation and inactivation can be the basis for how species produce unique individuals. Some processes that change gene activity are well understood in the context...
A team of Clemson University scientists has achieved a breakthrough in the genetics of senescence in cereal crops with the potential to dramatically impact the future of food security in the era of climate change.
The collaborative research, which explores the...
The diagram depicts the interplay between calcium and RGS2 during egg development and fertilization. RGS2 suppresses calcium signaling long enough for the sperm to travel and fuse with the egg.

Starting about 7,000 years ago, something weird seems to have happened to men: Over the next two millennia, recent studies suggest, their genetic diversity —specifically, the diversity of their Y chromosomes—collapsed. So extreme was that collapse that it was...
