Scientists have discovered that a protein once thought to be just a cellular "courier" actually helps plants survive drought. This motor protein, myosin XI, plays a critical role in helping leaves close their pores to conserve water. When it's ...
Scientists have uncovered a surprisingly simple “tissue code”: five rules that choreograph when, where, and how cells divide, move, and die, allowing organs like the colon to remain flawlessly organized even as they renew every few days. ...
Scientists have discovered that starving and then refeeding worms can reveal surprising secrets about aging. When a specific gene (called TFEB) is missing, these worms don’t bounce back from fasting—they instead enter a state that looks a lot ...
In a remarkable twist of science, researchers have transformed a fungus long associated with death into a potential weapon against cancer. Found in tombs like that of King Tut, Aspergillus flavus was ...
During Earth's ancient Snowball periods, when the entire planet was wrapped in ice, life may have endured in tiny meltwater ponds on the surface of equatorial glaciers. MIT researchers discovered ...
Nematodes tiny yet mighty form wriggling towers to survive and travel as a team. Long thought to exist only in labs, scientists have now spotted these towers naturally forming in rotting orchard fruit. Remarkably, the worms aren t just piling up ...
The biosynthesis of the great variety of natural plant products has not yet been elucidated for many medically interesting substances. In a new study, an international team of researchers was able to ...
Scientists in Australia have developed a smart, bacteria-repelling coating based on resilin the ultra-elastic protein that gives fleas their legendary jumping power. When applied to surfaces like medical implants or surgical tools, the engineered ...
Laboratory could improve crop resilience In a discovery three decades in the making, scientists have acquired detailed knowledge about the internal structures and mode of regulation for a specialized protein and are proceeding to develop tools that ...
Obesity is a global health problem that affects many people. In recent years, very promising anti-obesity drugs have been developed. Despite these successes, there are patients who do not respond to these drugs or suffer from side effects. ...
The protein DNase1 is one of the oldest biological agents in history: It has been on the market since 1958 and is now used, among other things, to treat cystic fibrosis. However, it takes considerable effort to produce it in immortalized hamster ...
Scientists analyzed almost 200 cannabis genomes to create the most comprehensive, high-quality, detailed genetic atlas of the plant to date. The atlas reveals unprecedented diversity and complexity within the species, sets the stage for advances in ...

A new concept of kinetic modules in biochemical networks could revolutionize the understanding of how these networks function. Scientists succeeded in linking the structure and dynamics of ...

A new study reveals the biological secret to the Zika virus's infectious success: Zika uses host cells' own 'self-care' system of clearing away useless molecules to suppress the ...

Scientists have discovered cells in the skin of Atlantic salmon that offer new insights into how wounds heal, tissues regenerate, and cellular transitions support long-term skin ...

Flowers grow stems, leaves and petals in a perfect pattern again and again. A new study shows that even in this precise, patterned formation in plants, gene activity inside individual cells is far ...

In biology, enzymes have evolved over millions of years to drive chemical reactions. Scientists have now derived universal rules to enable the de novo design of optimal enzymes. As an example, they ...

The molecular pathways involved in antiviral defenses and counter-defenses in host-pathogen systems remain unclear. Researchers have used Neurospora crassa as a model organism to explore how RNA ...

Proteins catalyze life by changing shape when they interact with other molecules. The result is a muscle twitching, the perception of light, or a bit of energy extracted from food. The ability to ...

A new study proves that a type of genetic element called 'introners' are the mechanism by which many introns spread within and between species, also providing evidence of eight instances in ...

The bacteria that cause tuberculosis (TB) may have an 'on-off switch' that lets them pause and restart growth, according to a new study. The research helps explain why TB is so hard to ...

Researchers uncover a notorious cholera strain that contains sophisticated immune systems to fend off viruses, which potentially helped it to fuel a devastating epidemic across Latin ...

A study has uncovered a surprising link between diet, intestinal microbes and the efficacy of cancer ...

Researchers have shown that gonadotrophs, cells in the pituitary gland with a key role in puberty and reproduction, come from two different populations, with the majority produced after birth rather ...

Bats are known as natural hosts for highly pathogenic viruses such as MERS- and SARS-related coronaviruses, as well as the Marburg and Nipah viruses. In contrast to the severe and often fatal disease ...

Songbirds who make the arduous flight from their nesting sites in northern boreal forests to warm, southern climates in the winter may be rewarded for their journey with greater genetic ...

Two of the traits that set modern humans apart from non-human primates are taller stature and a higher basal metabolic rate. Researchers have identified a genetic variant that contributed to the ...

Researchers developed a way to extend the shelf life of vegetables by injecting them with melatonin using biodegradable ...

A team of scientists has answered a long-standing question in cell biology, uncovering how the cell's main energy currency, ATP, is transported into the endoplasmic reticulum (ER). Disrupted ...

With its fascinating ability to regrow entire limbs and internal organs, the Mexican axolotl is the ideal model for studying regeneration. Scientists have now found a factor that tells cells which ...

Cancer cells respond to stress with greater diversity. Drugs that affect DNA replication, or radiation that causes direct DNA damage, lead to increasingly diverse offspring over multiple cell ...

Proteins are among the most studied molecules in biology, yet new research shows they can still hold surprising secrets. Researchers have discovered previously undetected chemical bonds within ...
