Of the honey bee dance
Honey bees are unique in that they not only alert their nestmates but have also evolved a symbolic communication in the form of a dance - a waggle dance.

Kanazawa University scientists use computer simulations of charged molecules to help improve the accuracy of mass spectrometers. By understanding the collisions between ions that reduce excess charges, this work may lead to more sensitive radiocarbon dating and medical testing.
"Stripy zebra, spotty leopard..." Pattern formation and pattern recognition entertains children and scientists alike. Alan Turing's 1950s model explaining patterns in two-substance systems is used by metallurgists to explain microscopic internal stripes and spots. A study out today explains exotic patterns, counter to Turing's theory, forming on the liquid metal gallium, which melts in the hand. The previously ignored surface-solidification phenomenon improves fundamental understanding of liquid-metal alloys... Читать дальше...
Fungi are capable of processing information in the same way as a computer.
The compulsory collection of DNA being undertaken in some parts of the world is not just unethical, but risks affecting people's willingness to donate biological samples and thus contribute to the advancement of medical knowledge and the development of new treatments, says a paper in the European Journal of Human Genetics.
POSTECH Professor Jang-Sik Lee's research team develops ferroelectric NAND flash memory.
A new study published in EPJ C by Alexei Morozov and Nikita Tselousov, from the Institute of Theoretical and Experimental Physics and the Institute of Transmission Problems, Moscow, respectively, details peculiar solutions to the Maxwell equations--so-called Maxwell knots. The research could have applications in the fields of mathematical physics and string theory.
In a memo to staff on Monday, Race and Ethnicity Editor Andale Gross announced that Kat Stafford has been named AP national investigative race writer:
Primary care physicians (PCPs) are seen as gatekeepers to reduce spending on low-value health care services, which have been estimated to cost the health care system up to $100 billion annually. A brief research report published in Annals of Internal Medicine analyzed how much low-value spending is directly related to PCPs' services and referral decisions.
Overall, the green MED diet produced dramatic reductions in fatty liver. NAFLD prevalence dropped from 62% at baseline to 31.5% in the green Mediterranean group, down to 47.9% in the Mediterranean group and 54.8% in the healthy dietary regimen group. Addressing this common liver disease by targeted lifestyle intervention might promote a more effective nutritional strategy. This Ben-Gurion University of the Negev clinical trial demonstrates an effective nutritional tool for NAFLD beyond weight loss
New research has demonstrated that a simple, cheap test can help identify who is at risk of developing colorectal cancer, aiding early diagnosis and potentially saving lives.
Fried-food intake is linked to a heightened risk of major heart disease and stroke, finds a pooled analysis of the available research data, published online in the journal Heart.
We should err on the side of caution and stop the global roll out of 5G (fifth generation) telecoms networks until we are certain this technology is completely safe, urges an expert in an opinion piece published online in the Journal of Epidemiology & Community Health.
Government obesity policies in England over the past three decades have largely failed because of problems with implementation, lack of learning from past successes or failures, and a reliance on trying to persuade individuals to change their behaviour rather than tackling unhealthy environments. This is the conclusion of new research by a team at the University of Cambridge funded by the NIHR School for Public Health Research.
Young Seychelles warblers fare better if their elderly parents have help raising them, according to new research from the University of East Anglia (UEA) and the University of Groningen.Seychelles warblers, a cooperatively breeding species of songbird that lives in small family groups, share the care of young between parents and helpers. This collaboration can compensate for a decline in the ability of elderly parents to provide sufficient care, the researchers found.
The incoming Biden administration looks to roll back Trump-era policies.
Implausible claims of voter fraud shouldn’t invalidate the case for real reform—we need to harden our electoral system against disaster.
A brain region involved in processing information about ourselves biases our ability to remember, according to new research published in JNeurosci.
More people could be protected from life-threatening rabies thanks to an agile approach to dog vaccination using smart phone technology to spot areas of low vaccination coverage in real time. The work could help save the lives of children worldwide.
Click beetles can propel themselves more than 20 body lengths into the air, and they do so without using their legs. While the jump's motion has been studied in depth, the physical mechanisms that enable the beetles' signature clicking maneuver have not. A new study examines the forces behind this super-fast energy release and provides guidelines for studying extreme motion, energy storage and energy release in other small animals like trap-jaw ants and mantis shrimps.
A Canadian-led team of astronomers discovers that the core mass of exoplanet WASP-107b is much lower than previously thought possible for a gas-giant planet.
A new method to synthesize vaccines safely and quickly should see much faster pre-clinical testing to pursue strategies to combat novel pathogens, something the COVID pandemic has shown is necessary.
Range anxiety, the fear of running out of power before being able to recharge an electric vehicle, may be a thing of the past, according to a team of Penn State engineers who are looking at lithium iron phosphate batteries that have a range of 250 miles with the ability to charge in 10 minutes.
Targeted neuromodulation tailored to individual patients' distinctive symptoms is an increasingly common way of correcting misfiring brain circuits in people with epilepsy or Parkinson's disease. Now, scientists at UC San Francisco's Dolby Family Center for Mood Disorders have demonstrated a novel personalized neuromodulation approach that -- at least in one patient -- was able to provide relief from symptoms of severe treatment-resistant depression within minutes.
Research focuses on transient nature of species' and ecosystem stability; illustrates how prepare for possible flips.
