(HealthDay)—When you think of effective cardio exercise, the activities most likely to come to mind are aerobics classes, running, swimming and cycling. But racquet sports like tennis may hold even greater benefits, according to research published in the British Journal of Sports Medicine.

Argentine fossils take oak and beech family history far into Southern Hemisphere
One of the world's most important plant families has a history extending much farther south than any live or fossil specimen previously recorded, as shown by chinquapin fruit and leaf fossils unearthed in Patagonia, Argentina, according to researchers.

Study illuminates how undifferentiated cells commit to their biological fate
From the light-sensing cones of the retina to the blood-pumping muscle of the heart to the waste-filtering units of the kidneys, the human body is made up of hundreds of cell types exquisitely specialized to perform their jobs with great precision.

Organic electronics: A new semiconductor in the carbon-nitride family
Teams from Humboldt-Universität and the Helmholtz-Zentrum Berlin have explored a new material in the carbon-nitride family. Triazine-based graphitic carbon nitride (TGCN) is a semiconductor that should be highly suitable for applications in optoelectronics. Its structure is two-dimensional and reminiscent of graphene. Unlike graphene, however, the conductivity in the direction perpendicular to its 2-D planes is 65 times higher than along the planes themselves.

Discovery sheds light on synthesis, processing of high-performance solar cells
Halide perovskite solar cells hold promise as the next generation of solar cell technologies, but while researchers have developed techniques for improving their material characteristics, nobody understood why these techniques worked. New research sheds light on the science behind these engineering solutions and paves the way for developing more efficient halide perovskite solar cells.

Autonomous boats can target and latch onto each other
The city of Amsterdam envisions a future where fleets of autonomous boats cruise its many canals to transport goods and people, collect trash, or self-assemble into floating stages and bridges. To further that vision, MIT researchers have given new capabilities to their fleet of robotic boats—which are being developed as part of an ongoing project—that lets them target and clasp onto each other, and keep trying if they fail.

Scientists recreate blood-brain barrier defect outside the body
Scientists can't make a living copy of your brain outside your body. That's the stuff of science fiction. But in a new study, they recreated a critical brain component, the blood-brain barrier, that functioned as it would in the individual who provided the cells to make it. Their achievement—detailed in a study published today in the peer-reviewed journal Cell Stem Cell—provides a new way to make discoveries about brain disorders and, potentially, predict which drugs will work best for an individual patient.

How to speed up the discovery of new solar cell materials
A broad class of materials called perovskites is considered one of the most promising avenues for developing new, more efficient solar cells. But the virtually limitless number of possible combinations of these materials' constituent elements makes the search for promising new perovskites slow and painstaking.

Novel tools bridge the information gap between citizens and electricity grid operators
It's generally agreed that a low-carbon economy is important if we're to combat climate change. One obvious way to do this is to modernize our current power transmission grids so that we can make electricity more secure, affordable and sustainable. However, while this may seem straightforward in theory, in reality things aren't always so simple. New grid projects often face strong opposition by the organizations and communities they affect. When such opposition is added to the lengthy process of obtaining the necessary permits that can last up to 10 years, many of these projects are delayed or even canceled.
