A sustained dialogue must be established between molecular ecologists, policymakers and other stakeholders for DNA-based approaches to be adopted in marine monitoring and assessment, according to KAUST scientists and colleagues.
A decade-long study of the iconic fish has found male whale sharks grow quickly, before plateauing at an average adult length of about eight or nine metres.
Female whale sharks grow more slowly but eventually overtake the males, reaching an average adult length of about 14 metres.
Australian Institute of Marine Science fish biologist Dr Mark Meekan, who led the research, said whale sharks have been reported up to 18 metres long.
"That's absolutely huge--about the size of a bendy bus on a city street," he said.
Farmers around the world are keen to protect their most important asset: their soil. The soil supports and enriches their crops. But the relatively thin layer of topsoil can readily wash away into streams, carrying unwanted nutrients with it.

BINGHAMTON, NY -- BINGHAMTON, NY -- Biosensors that are wearable on human skin or safely used inside the body are increasingly prevalent for both medical applications and everyday health monitoring. Finding the right materials to bind the sensors together and adhere them to surfaces is also an important part of making this technology better. A recent study from Binghamton University, State University of New York offers one possible solution, especially for skin applications.
WASHINGTON, September 15, 2020 -- Nanogenerators capable of converting mechanical energy into electricity are typically made from metal oxides and lead-based perovskites. But these inorganic materials aren't biocompatible, so the race is on to create natural biocompatible piezoelectric materials for energy harvesting, electronic sensing, and stimulating nerves and muscles.
WASHINGTON, September 15, 2020 -- Four-hundred fifty light-years from Earth, a young star is glowing at the center of a system of concentric rings made from gas and dust, and it is producing planets, one for each gap in the ring.
Its discovery has shaken solar system origin theories to their core. Mayer Humi, a scientist from the Worcester Polytechnic Institute, believes it provides an apt study target for theories about protoplanetary rings around stars. The research is published in the Journal of Mathematical Physics, by AIP Publishing.
San Diego, CA - The COVID-19 pandemic has created a number of challenges, including that many are spending more time at home than ever before. This is a significant problem for those with neighbors who smoke. Smoking continues to be a problem in multi-unit housing, and while stay-at-home orders have helped to reduce transmission of COVID-19, they have also increased exposure to secondhand smoke from neighbors.
The growing demands for ultrahigh energy density batteries used in electronic devices, electrical vehicles, and large-scale energy storage have inspired wide search on novel electrode materials, especially high-capacity cathode materials for Li-ion batteries (LIBs). The traditional design paradigm for the transition-metal oxide (TMO) based cathodes, e.g., LiCoO2, LiMn2O4, LiFePO4 are to use TM as the sole source of electrochemical activity, and their theoretical capacity is limited by the number of electrons that TM can exchange per unit mass.
Osaka, Japan - How do you turn on and off an ultra-small component in advanced technologies? You need an actuator, a device that transmits an input such as electricity into physical motion. However, actuators in small-scale technologies to date have critical limitations. For example, if it's difficult to integrate the actuator into semiconductor electronics, real-world applications of the technology will be limited. An actuator design that operates quickly, has precise on/off control, and is compatible with modern electronics would be immensely useful.
Quantum technology holds great promise: Just a few years from now, quantum computers are expected to revolutionize database searches, AI systems, and computational simulations. Today already, quantum cryptography can guarantee absolutely secure data transfer, albeit with limitations. The greatest possible compatibility with our current silicon-based electronics will be a key advantage.
Hodgkin lymphoma is one of the most common hematological cancers and is an example of how medical research has changed the prognosis of the disease. If a few decades ago it was a tumor with a very bad clinical evolution in almost all patients, the introduction of new drugs has made it a curable tumor in 85% of cases. However, there is 15% of Hodgkin lymphomas that do not respond to therapy and that continue to have a reduced survival.
Infrared imagery is like having night vision, and NASA-NOAA's Suomi NPP satellite provided a nighttime view of Tropical Storm Vicky that revealed outside winds are weakening the storm.
About Wind Shear
The shape of a tropical cyclone provides forecasters with an idea of its organization and strength. When outside winds batter a storm, it can change the storm's shape. Winds can push most of the associated clouds and rain to one side of a storm. Outside winds from the southwest are pushing against Tropical Storm Vicky.
FORT LAUDERDALE/DAVIE, Fla. - They are some of the most iconic and unique-looking creatures in our oceans. While some may think they look a bit "odd," one thing researchers agree on is that little is known about hammerhead sharks. Many of the 10 hammerhead shark species are severely overfished worldwide for their fins and in need of urgent protection to prevent their extinction.
NASA's Aqua satellite analyzed the cloud top temperatures and water vapor content in Hurricane Sally as it crawls toward landfall, and found the potential for large amounts of rainfall, which, coupled with slow movement, can lead to catastrophic flooding. Two instruments provided three views of Sally's temperatures and water vapor that revealed the soaking capability of the slow-moving hurricane.
