The evolution of red color vision in lycaenid butterflies linked to coordinated rhodopsin tuning
The colors in a flower patch appear completely different to a bear, a honeybee, a butterfly and humans. The ability to see these colors is generated by specific properties of opsins—light-sensitive proteins in the retina of our eyes. The number of opsins expressed and the molecular structure of the receptor proteins determines the colors we see.

Hydrogel promotes wound healing better than traditional bandages, gauzes
For explosion wounds as well as some incurred in disasters and accidents, severe hemorrhage is a leading cause of death. Hydrogel dressings, which have advanced in recent years, may help; they are good at promoting wound healing and can better meet the demands of different situations. Many are antibacterial, biodegradable, responsive, and injectable and can fill irregularly shaped wounds.

In 2019, the JGI's Yasuo Yoshikuni and his team announced in Nature Microbiology an important addition to the synthetic biologist's toolkit: a technique for chassis (or strain)-independent recombinase-assisted genome engineering (CRAGE). CRAGE enables scientists to insert large pieces of DNA (up to 60 kb) in a single step, directly into the genome.

How the 3-D structure of eye-lens proteins is formed
The lens of the human eye gets its transparency and refractive power from the fact that certain proteins are densely packed in its cells. These are mainly crystallines. If this dense packing cannot be maintained, for example due to hereditary changes in the crystallines, the result is lens opacities, known as cataracts, which are the most common cause of vision loss worldwide.

The Srs2 helicase dampens DNA damage checkpoint by recycling RPA from chromatin [Genetics]
The DNA damage checkpoint induces many cellular changes to cope with genotoxic stress. However, persistent checkpoint signaling can be detrimental to growth partly due to blockage of cell cycle resumption. Checkpoint dampening is essential to counter such harmful effects, but its mechanisms remain to be understood. Here, we show that…

Pruritus is a common symptom of inflammatory skin conditions, including atopic dermatitis (AD). Although primary sensory neurons that transmit pruritic signals are well-cataloged, little is known about the neuronal alterations that occur as a result of skin disruption in AD. To address this question, we examined the molecular and behavioral…

Acid-sensing ion channels (ASICs) are expressed in the nervous system, activated by acidosis, and implicated in pain pathways. Mambalgins are peptide inhibitors of ASIC1 and analgesic in rodents via inhibition of centrally expressed ASIC1a and peripheral ASIC1b. This activity has generated interest in mambalgins as potential therapeutics. However, most mechanism…

DAF-12 is nematode-specific nuclear receptor that has been proposed to govern development of the infectious stage of parasitic species, including Strongyloides stercoralis. Here, we identified a parasite-specific coactivator, called DAF-12 interacting protein-1 (DIP-1), that is required for DAF-12 ligand-dependent transcriptional activity. DIP-1 is found only in Strongyloides spp. and selectively.

Plant cystatins are cysteine proteinase inhibitors that play key roles in defense responses. In this work, we describe an unexpected role for the cystatin-like protein DEFORMED FLORAL BUD1 (CsDFB1) as a transcriptional regulator of local auxin distribution in cucumber (Cucumis sativus L.). CsDFB1 was strongly expressed in the floral meristems,…

Meiosis is a specialized cell division that creates haploid germ cells from diploid progenitors. Through differential RNA expression analyses, we previously identified a number of mouse genes that were dramatically elevated in spermatocytes, relative to their very low expression in spermatogonia and somatic organs. Here, we investigated in detail 1700102P08Rik,…

How old are the oldest Homo sapiens in Far East Asia? [Genetics]
There is abundant genetic and paleontological evidence supporting the African origin of our species. At some point in its evolution, Homo sapiens spread out of Africa into Eurasia, replacing or partially absorbing local populations of other hominin forms. Ultimately, it colonized regions where no humans had ever lived before. Although…

‘Couple simulation’ better models mate selection
A new “couple simulation” model offers insights into the mysteries of mate selection. In your quest for true love and that elusive happily ever after, are you waiting for the “right” person to come along, or do you find yourself going for the cutest person in the room, hoping things will work out? Do you leave your options open, hoping to “trade-up” at the next opportunity, or do you invest in yo

Ultrafast electron dynamics in space and time
Often depicted as colourful balloons or clouds, electron orbitals provide information on the whereabouts of electrons in molecules, a bit like fuzzy snapshots. In order to understand the exchange of electrons in chemical reactions, it is not only important to know their spatial distribution but also their motion in time. Scientists from Julich, Marburg, and Graz have now made huge progress in this
