Genetic engineering. Conceptual illustration of a human figure and a strand of the genetic molecule DNA (deoxyribonucleic acid), with laboratory equipment representing research into genetic engineering. Genetic modification, which involves the alteration of an organism's genetic make-up, is used to treat diseases and disorders in many areas of medicine.

E. coli bacterium and nanoparticles. Illustration of metal nanoparticles interacting with an Escherichia coli bacterium. E. coli has been investigated as a medium for storing and encrypting data in bacterial DNA (deoxyribonucleic acid). Bacterial biostorage systems could hold vast amounts of data, and the concept could also be used to create biological barcodes. The nanoparticles could also be attacking and destroying the bacterium. E. coli bacteria are a normal part of the intestinal flora in humans and other animals, where they aid digestion. However, some strains can produce a toxin that leads to severe illness, or even death. Normal strains can also produce infections in those with weakened immune systems.

Diagram showing the variation of a Cepheid variable over time with strict periodicity. Cepheids are pulsating variable stars, whose spectral type and luminosity class (and therefore their brightness and size) vary over a few days to months. The prototype is Delta Cephei. As they grow larger, they cool down and get redder, while their brightness drops. The green curve shows the variation in radius; the red, the change in brightness. The orange dashes indicate the period. They fall into two main classes. Type I Cepheids are bright yellow giants and supergiants, thousands of times more luminous than the Sun and several times more massive. They vary their radius by as much as 25 per cent. Type II Cepheids are much less massive, around half that of the Sun. The variations of many Cepheids, such as the prototype, can easily be seen with the naked eye ever a period of days or weeks.

Jurkat cell. Coloured scanning electron micrograph (SEM) of dividing Jurkat cells. The Jurkat cell line is an immortalized T lymphocyte cell line that was originally obtained from the peripheral blood of a boy with T cell leukemia. The Jurkat cell line has most often been used as a prototypical T cell line to study multiple events in T cell biology, including T cell signaling and molecular events in the HIV infection life cycle.

Editorial use only Fossil analysis at Neanderthal excavation site. Researchers analysing and cataloguing fossils from the Pinilla del Valle site, in the Lozoya Valley, near Madrid, Spain. As well as animal fossils, several Neanderthal fossils have been found here. The animal fossils show the environment the Neanderthals lived in. Neanderthals (Homo neanderthalensis) inhabited Europe and western Asia between 230,000 and 29,000 years ago. Excavations at this site have been taking place since around 2002. Photographed in 2017.

PCSK9 inhibition by monoclonal antibody. Illustration of a molecule of the enzyme proprotein convertase subtilisin/kexin type 9 (PCSK9, white and pink) bound to a monoclonal antibody (blue and pale blue). PCSK9 binds to the receptor for low-density lipoprotein particles (LDL). The LDL receptor (LDLR), on liver and other cell membranes, binds and initiates ingestion of LDL-particles from extracellular fluid into cells. Blocking PCSK9 can lower blood LDL-particle concentrations. When there are high levels of LDL ('bad' cholesterol) in the blood it builds up on the sides of blood vessels hardening them, a condition named atherosclerosis. Monoclonal antibodies that bind to and inhibit PCSK9 are being used to reduce the amount of cholesterol in the blood by improving the liver's ability to recycle LDLRs.

Goldschmidt periodic table classification. Modern periodic table showing 118 elements from hydrogen to oganesson, colour-coded according to how they are found in nature. This classification is named after the Swiss-Norwegian geochemist Victor Goldschmidt (1888-1947). The types are: atmophile (light pink); lithophile (brown); siderophile (green); chalcophile (beige), very rare or synthetic (light purple). Atmophiles are associated with the atmosphere; lithophiles react with oxygen and form light minerals; siderophiles form heavier minerals; chalcophiles react with sulphur and are between lithophiles and siderophiles in density within the Earth.

Baricitinib is used to treat arthritis, both alone and in combination with methotrexate. The compound is a reversible inhibitor of Janus kinase enzymes. Baricinitib was approved for use in the EU in 2017, but the USFDA has refused to approve the drug, citing concerns over safety and dosage.

Water transport across cell membrane, illustration. Water (blue) is shown crossing a cell membrane. Water carried across a semi-permeable membrane by solute molecules is a process known as osmosis. In addition to this, water transport is aided by membrane proteins known as aquaporins that form channels that help water molecules pass in and out of the cell. Unlike ion channels, aquaporins help prevent ions and other dissolved substances carrying electrical charge from entering the cell, as they only allow lone water molecules or certain uncharged solutes to pass through. This helps to maintain the electrochemical potential of the membrane.

Antibiotic resistance, conceptual composite image. Scanning electron microscopy (SEM) and computer generated image (CGI) of DNA (deoxyribonucleic acid, orange/cyan) and a bacillus. Bacteria can become resistant to antibiotics that have previously harmed them. Bacteria can acquire resistance in two ways: either through a spontaneous genetic change that confers resistance, or by transfer of DNA from a bacterium that is already resistant. Even a simple DNA change can protect the bacteria if it affects the protein on which an antibiotic acts. Transfer of genes between bacteria is common, including the transfer of genes for antibiotic resistance.

Editorial use only Neanderthal excavation. Researchers carrying out excavations for prehistoric human fossils at the Pinilla del Valle site, in the Lozoya Valley, near Madrid, Spain. Several Neanderthal fossils have been found here. Neanderthals (Homo neanderthalensis) inhabited Europe and western Asia between 230,000 and 29,000 years ago. They did not use complex tools but had mastery of fire and built shelters. It is thought that they had language and a complex social structure, living in small family groups and hunting for food. Excavations by around 70 people have been taking place here every summer for over a decade since around 2002. Photographed in August 2016.
