Brain folding related to surface area and thickness, not number of neurons
(Medical Xpress)—A pair of researchers with Universidade Federal do Rio de Janeiro has found that the degree of folding of mammalian brains follows a simple mathematical relationship. In their paper published in the journal Science, Bruno Mota and Suzana Herculano-Houzel describe how they came up with the math and its implications regarding the developmental and evolutionary origins of brain folding. George Striedter and Shyam Srinivasan with the University of California offer a Commentary piece on the work done by the duo in the same journal issue.

Waiting to harvest after a rain enhances food safety
To protect consumers from foodborne illness, produce farmers should wait 24 hours after a rain or irrigating their fields to harvest crops, experts say. Rain or irrigation creates soil conditions that are more hospitable to Listeria monocytogenes, which when ingested may cause the human illness Listeriosis. Waiting to harvest crops reduces the risk of exposure to the pathogen, which could land on fresh produce.

REM sleep critical for young brain development; medication interferes
Rapid eye movement or REM sleep actively converts waking experiences into lasting memories and abilities in young brains, reports a new study. The finding broadens the understanding of children's sleep needs and calls into question the increasing use of REM-disrupting medications such as stimulants and antidepressants.

Novel DNA repair mechanism brings new horizons
The DNA molecule is chemically unstable giving rise to DNA lesions of different nature. That is why DNA damage detection, signaling and repair, collectively known as the DNA damage response, are needed. A group of researchers has discovered a new mechanism of DNA repair, which opens up new perspectives for the treatment and prevention of neurodegenerative diseases.

Second-line cetuximab active beyond progression in quadruple wild-type patients with mCRC
(European Society for Medical Oncology) Patients with metastatic colorectal cancer (mCRC) that are mutation-free in the KRAS, NRAS, BRAF and PIK3CA genes showed significant benefit from continuing anti-epidermal growth factor receptor (EGFR) therapy beyond progression following first-line chemotherapy and an anti-EGFR monoclonal antibody, according to study results presented at the ESMO 17th World Congress on Gastrointestinal Cancer in Barcelona, Spain.

'Invisible' protein structure explains the power of enzymes
(Umea University) A research group at Umeå University in Sweden has managed to capture and describe a protein structure that, until now, has been impossible to study. The discovery lays the base for developing designed enzymes as catalysts to new chemical reactions for instance in biotechnological applications. The result of the study is published in the journal Nature Communications.

Early exposure to cat urine makes mice less likely to escape from cats
(Society for Experimental Biology) Mice that are exposed to the powerful smell of cat urine early in life do not escape from cats later in life. Researchers at the A. N. Severtsov Institute of Ecology and Evolution, Russia, have discovered that mice that smell cat urine early in life, do not avoid the same odor, and therefore do not escape from their feline predators, later in life.
