Free fingers have many obvious advantages on land, such as in locomotion and grasping, while webbed fingers are typical of aquatic or gliding animals. But both amphibians and amniotes—which include mammals, reptiles, and birds—can have webbed digits. In new research from Japan, scientists show for the first time that during embryo development, some animal species detect the presence of atmospheric oxygen, which triggers removal of interdigital webbing. Their research appears June 13 in the journal Developmental Cell.

Implanted drug 'reservoir' safely reduces injections for people with macular degeneration
In a clinical trial of 220 people with "wet" age-related macular degeneration, Johns Hopkins Medicine researchers, collaborators from many sites across the country, and Genentech in South San Francisco have added to evidence that using a new implant technology that continuously delivers medication into the eyes is safe and effective in helping maintain vision and reduces the need for injections in the eyes.

Breaking the code: How is a mother's immunity transferred to her baby?
One of the most successful interventions in reducing infectious disease worldwide, vaccination still has limited effectiveness in protecting one group of patients—newborn infants. Now a study based at the Ragon Institute of MGH, MIT and Harvard has determined how a pregnant woman's vaccine-induced immunity is transferred to her child, which has implications for the development of more effective maternal vaccines. The report will be published in the June 27 issue of Cell and is receiving early online release.

Researchers show glare of energy consumption in the name of deep learning
Wait, what? Creating an AI can be way worse for the planet than a car? Think carbon footprint. That is what a group at the University of Massachusetts Amherst did. They set out to assess the energy consumption that is needed to train four large neural networks.

Immunotherapy drug shows potential to cure advanced lung cancer
In a new study including Yale Cancer Center and Smilow Cancer Hospital researchers, the cancer immunotherapy drug pembrolizumab (Keytruda), increased survival for patients with advanced non-small cell lung cancer (NSCLC), a disease once considered an aggressive, and uniformly fatal cancer. The findings were presented at the American Society of Clinical Oncology (ASCO) annual meeting in Chicago.

Researchers create uniform-shape polymer nanocrystals
A team of researchers from the University of Konstanz has demonstrated a new aqueous polymerization procedure for generating polymer nanoparticles with a single chain and uniform shape, which, by contrast to previous methods, involves high particle concentrations. A corresponding paper titled "Uniform shape monodisperse single chain nanocrystals by living aqueous catalytic polymerization" is set for publication in Nature Communications.

Researchers influence CDC's clarification on prescribing opioids for cancer pain
To reduce the number of people who may misuse, abuse, or overdose from opioids, multiple national agencies including the Centers for Disease Control and Prevention (CDC) have published guidelines to improve the way opioids are prescribed. Yet some of these guidelines have caused confusion and misapplication among clinicians and unintendedly limited treatment of pain for people with cancer.
