Bottlenose dolphins can sense electric fields, study shows

Posted by in categories: biotech/medical, neuroscience

A small team of bio-scientists from the University of Rostock’s Institute for Biosciences and Nuremberg Zoo’s Behavioral Ecology and Conservation Lab, both in Germany, has found evidence that bottlenose dolphins can sense electric fields. In their study, reported in the Journal of Experimental Biology, the group tested the ability of two captive bottlenose dolphins to sense a small electric field.

Many creatures in the are able to sense an electric field—some sharks and the platypus, for example—but only one type of marine mammal has been found to have the ability: the Guiana dolphin. In this new effort, the research team wondered if other types of dolphins have the ability.

They chose to study for two reasons: a pair of were available for testing at the nearby Nuremberg Zoo, and prior research suggested that neural cells in the vibrissal crypts situated along the dolphins’ snouts strongly resembled the electric-field detectors observed in sharks.

Amazon buys 3 launches with SpaceX for Project Kuiper

Posted by in categories: internet, satellites

Amazon announced today they have bought 3 Falcon 9 launches to deliver their Project Kuiper internet satellites to low Earth orbit in mid-2025.

This wouldn’t be the first time SpaceX has launched a competitor satellite as they have now launched 4 times for one of their other competitors, OneWeb, with a total of 136 satellites delivered to orbit.

Amazon recently made the decision to move up the launch of their first Project Kuiper satellites from United Launch Alliance’s Vulcan rocket which has faced numerous delays to an Atlas V that launched on October 6th.

Edge of Chaos Theory | Cellular Automata, Wolfram, & Psychology

Posted by in categories: mathematics, philosophy

Order vs Disorder, Jordan Peterson’s Yin Yang analogy, & Stephen Wolfram’s 4 classes of cellular automata are explored. The edge of chaos is the phase transition zone between order and disorder which is found across a broad range of complex systems. We discuss Norman Packard, Christopher Langton, John Beggs, Stuart Kauffman, Mihaly Csikszentmihalyi, and M. Mitchell Waldrop. Wolfram’s Rule 110 and John Conway’s Game of Life, both Turing complete, make appearances.

World’s biggest set of human genome sequences opens to scientists

Posted by in categories: biotech/medical, genetics

The world’s largest collection of full human genomes has just gone live.

The whole genomes of 500,000 people in the UK Biobank will help researchers to probe our genetic code for links to disease.

Hope, sadness as volunteers search for victims of Indonesian volcano

Posted by in category: futurism

At the foot of Indonesia’s Mount Semeru, what is left of the houses along the main village road are covered in a thick layer of hardened volcanic ash. Curah Kobokan was among the worst-hit areas when the 3,676-metre (12,060 ft) Mount Semeru erupted on Saturday, sending a cloud of ash into the sky and dangerous pyroclastic flows into villages below. Since day one of the disaster, volunteer Dodik Suryadiawan, 36, has driven on the bumpy roads in his personal four-wheel drive, helping to retrieve the remains of those who perished.

‘Tremendous technical challenges’: New report says NASA won’t land astronauts on the moon in 2025

Posted by in categories: government, space travel

Man’s return to the moon may be delayed from 2025 until 2027.

BREVARD COUNTY, Fla. — NASA will miss its mark trying to land astronauts on the moon by 2025. That’s according to a new report, released by the Government Accountability Office (GAO) this week.

“There are tremendous technical challenges that have to be resolved,” said Ken Kremer. He’s a space journalist in Brevard County who read and analyzed the new report.

Long in the Bluetooth: Scientists develop a more Efficient way to Transmit Data between Our Devices

Posted by in categories: mobile phones, wearables

University of Sussex researchers have developed a more energy-efficient alternative to transmit data that could potentially replace Bluetooth in mobile phones and other tech devices. With more and more of us owning smart phones and wearable tech, researchers at the University of Sussex have found a more efficient way of connecting our devices and improving battery life. Applied to wearable devices, it could even see us unlocking doors by touch or exchanging phone numbers by shaking hands.

Professor Robert Prance and Professor Daniel Roggen, of the University of Sussex, have developed the use of electric waves, rather than electromagnetic waves, for a low-power way to transmit data at close range, while maintaining the high throughput needed for multimedia applications.

Bluetooth, Wifi, and 5G currently rely on electromagnetic modulation, a form of wireless technology which was developed over 125 years ago.

Certain Skin Bacteria can Inhibit Growth of Antibiotic-Resistant Bacteria

Posted by in category: biotech/medical

Researchers have found a bacteriocin that can help inhibit the growth of antibiotic-resistant bacteria. Infections with antibiotic-resistant bacteria are a growing global problem. Part of the solution may lie in copying the bacteria’s own weapons. The research environment in Tromsø has found a new bacteriocin, in a very common skin bacterium. Bacteriocin inhibits the growth of antibiotic-resistant bacteria that are often the cause of disease and can be difficult to treat.

One million deaths each year.

The fact that we have medicines against bacterial infections is something many people take for granted.
