A that gene provides both protection and destruction

The family of ENDOU enzymes is found in most organisms, yet its functions are only poorly understood. In humans, it has been connected with cancer. RNA viruses, such as SARS-CoV2, contain a gene corresponding to ENDOU, and ...

Video: Green algae reveals that one mRNA encodes many proteins

Gene expression in eukaryotes was long held to be monocistronic—that is, a single gene makes messenger RNA, which encodes a single protein. Recently reported in the Proceedings of the National Academy of Sciences, a team ...

An mRNA vaccine for cancer immunotherapy

Messenger RNA (mRNA) vaccines to prevent COVID-19 have made headlines around the world recently, but scientists have also been working on mRNA vaccines to treat or prevent other diseases, including some forms of cancer. Now, ...

Study offers new insights into fragile X syndrome

A new study shows that many abnormalities in fragile X syndrome cells are related to glitches with one of the body's major quality control systems. Published in Nature Cell Biology, the research provides fresh insight into ...

Researchers have uncovered one way plants respond to hormonal cues

Just like other organisms, plants must respond dynamically to a variety of cues over their lifetime. Going through different developmental stages, or altering their form in response to a drought or drastic temperature change ...

Small molecules control bacterial resistance to antibiotics

(Friedrich-Schiller-Universitaet Jena) Antibiotics have revolutionized medicine by providing effective treatments for infectious diseases such as cholera. But the pathogens that cause disease are increasingly developing resistance ...

Mechanism discovered how the coronavirus hijacks the cell

Researchers at ETH Zurich and the University of Bern have discovered a mechanism by which the corona virus manipulates human cells to ensure its own replication. This knowledge will help to develop drugs and vaccines against ...

MESSENGER

The MErcury Surface, Space ENvironment, GEochemistry and Ranging (MESSENGER) space probe is a robotic NASA spacecraft in orbit around the planet Mercury. The 485-kilogram (1,070 lb) spacecraft was launched aboard a Delta II rocket in August 2004 to study the chemical composition, geology, and magnetic field of Mercury. It became the second mission after 1975's Mariner 10 to reach Mercury successfully when it made a flyby in January 2008, followed by a second flyby in October 2008, and a third flyby in September 2009. MESSENGER is furthermore the first spacecraft ever to orbit Mercury.

The instruments carried by MESSENGER were tested on a complex series of flybys – the spacecraft flew by Earth once, Venus twice, and Mercury itself three times, allowing it to decelerate relative to Mercury with minimal fuel. MESSENGER successfully entered Mercury's orbit on 18 March 2011, and reactivated its science instruments on 24 March, returning the first photo from Mercury orbit on 29 March. MESSENGER's formal science data collection mission began on 4 April 2011.
