Insights into the development of sperm and egg cell precursors in the embryo
Researchers at the Babraham Institute have investigated the early stages of the development of cells called primordial germ cells and developed strategies to generate 'lookalike' cells in the lab. The generation of human 'lookalike' primordial germ cells is of importance for future fertility studies and the analysis of potential transgenerational epigenetic inheritance in humans.

Core technology springs from nanoscale rods
Rice University scientists have demonstrated a method for reversibly changing the light emitted from metallic nanorods by moving atoms from one place to another inside the particles. The discovery could lead to a new type of multistate memory, as well as reconfigurable sensors and catalysts.

Could mental math boost emotional health?
Engaging the brain's dorsolateral prefrontal cortex (DL-PFC) while doing mental math may be connected with better emotional health, according to Duke researchers. Although they seem unrelated, doing 'cold' calculations and regulating 'hot' emotions both rely on similar mental gymnastics: the ability to manipulate and update information. Increased DL-PFC activity has been associated with fewer symptoms of anxiety and depression.

Climate change may benefit native oysters, but there's a catch
Climate change may actually benefit oysters in California in the long term because they grow faster at warmer temperatures and are tolerant of extreme temperatures. But first they would have to survive a spike in oyster drills, a predatory snail that also grows faster in warmer conditions but that is less tolerant of extreme conditions, according to a study from UC Davis Bodega Marine Laboratory.

Metamaterial uses light to control its motion
Researchers have designed a device that uses light to manipulate its mechanical properties. The device, which was fabricated using a plasmomechanical metamaterial, operates through a unique mechanism that couples its optical and mechanical resonances, enabling it to oscillate indefinitely using energy absorbed from light.

Study: Human-caused climate change has doubled western US forest fire area
Human-caused climate change has nearly doubled the amount of land burned in western US forest fires over the past three decades, according to a new study by researchers at the University of Idaho and Columbia University. The researchers estimate that human-caused climate change caused an additional 16,000 square miles of western forest lands to burn between 1984 and 2015.

This little amoeba committed grand theft
About 100 million years ago, a lowly amoeba pulled off a stunning heist, grabbing genes from an unsuspecting bacterium to replace those it had lost. Now Rutgers and other scientists have solved the mystery of how the little amoeba, Paulinella, committed the theft. It engulfed the bacterium, kept that cell alive and harnessed its genes for photosynthesis, the process plants and algae use to convert carbon dioxide into oxygen and sugar via solar energy.

Great apes can 'read minds'
Great apes watching a hide-and-seek video can process false beliefs, the notion that someone's understanding of a situation may not be congruent with reality. This challenges the view that the ability to understand unobservable mental states is unique to humans.

How gecko feet got sticky
Timothy Higham, a biologist at the University of California, Riverside, and two colleagues have found a gecko, Gonatodes humeralis, in Trinidad and French Guiana that offers a 'snapshot' into the evolution of adhesion in geckos. This padless gecko shows how the adhesive capabilities of pad-bearing geckos, such as tokay geckos, may have come about.

IU scientists discover 'supramolecule' that could help reduce nuclear, agricultural waste
A study from Indiana University published today in the German scientific journal Angewandte Chemie International Edition provides the first experimental proof for the existence of a chemical bond between two negatively charged molecules of bisulfate, or HSO4. The new molecular structure has potential applications to the safe storage of nuclear waste and reduction of chemicals that contaminate water and trigger large fish kills.

Holographic imaging and deep learning diagnose malaria
Researchers have devised a method for computers to autonomously and quickly diagnose malaria with clinically relevant accuracy. The method uses deep learning and light-based, holographic scans for computers to spot malaria-infected cells from a simple, untouched blood sample without any help from a human. The innovation could form the basis of a fast, reliable test that could be given by most anyone, anywhere in the field.

Enhancing the superconducting properties of an iron-based material
By bombarding the material with low-energy protons, scientists doubled the amount of current the material could carry without resistance, while raising the temperature at which this superconducting state emerges. Their method could be used to improve the performance of superconducting wires and tapes for electric vehicles, wind turbines, medical imaging devices, and other applications.
