To Get Complex Life, Just Add Oxygen

first_imgA story is circulating in the science news media that a burst of complex organisms in the Cambrian coincided with a rise in oxygen in the atmosphere.  Reporters seem to be drawing a cause-and-effect relationship.  Examples:[email protected]:  “A sharp increase in the amount of oxygen in the air may have sparked the evolution of complex animal life.”Queen’s University:  “Finding an answer to Darwin’s Dilemma: Oxygen may be the clue to first appearance of large animals, says Queen’s prof.”Science Daily:  “The close connection between the first appearance of oxygenated conditions in the world’s oceans and the first appearance of large animal fossils confirms the importance of oxygen as a trigger for the early evolution of animals, the researchers say.”The news relates to a paper published on Science Express.  The abstract shows that the premise is built on mere circumstantial evidence:Animals have an absolute requirement for oxygen, and an increase in late Neoproterozoic oxygen concentrations has been forwarded as a stimulus for their evolution.  The iron content of deep-sea sediments show that the deep ocean was anoxic and ferruginous before and during the Gaskiers glaciation 580 million years ago, becoming oxic afterward.  The first known members of the Ediacara biota are found shortly after the Gaskiers glaciation, suggesting a causal link between their evolution and this oxygenation event.  A prolonged stable oxic environment may have permitted the emergence of bilateral motile animals some 25 million years later.In a similar story (but further back in the evolutionary timeline), Science Now reported another chemical key to life.  “How in the world did life emerge on a planet composed only of simple chemical compounds?  Scientists say they may have found part of the answer in a mineral that seems to act as an effective catalyst for the earliest organic processes.”  The article calls this mineral, sphalerite, as “Nature’s Jump-Starter.”1Canfield et al, “Late-Neoproterozoic Deep-Ocean Oxygenation and the Rise of Animal Life,” Science, published Online December 7, 2006, Science DOI: 10.1126/science.1135013.There it is: the dead giveaway that the Darwinists are conjuring up miracles again: the word emergence.  This is how they dazzle the world with their wizardry and dupe the press.  The mere utterance of the word sends reporters into a trance, where dreams of evolution come true.  In their mythical lands of Ediacara and Gaskiers in the long-lost kingdom of Muddle Earth, the trolls and orcs forge monsters under the sea, their fires stoked with the miracle-working ether of oxygen, under the direction of Sauron’s minion, Tinker Bell.    Anything is possible in fiction.  Here, the only things required to make complex life emerge are requirements themselves.  “Animals have an absolute requirement for oxygen,” the wizards pronounce, so they add the magic ingredient to their potion, and presto!*  Complex animals with eyes, jointed articulating limbs, fins, molecular machines and coded languages simply emerge from the mix.  In the second article, a well-known chemical evolutionist (aka alchemist), in charmèd spirit, rejoices at the discovery of another putative philosopher’s stone that may bring us “a lot closer to understanding the chemical origins of life.”  Aren’t you fortunate to be living in the Age of Enchantment, where all you have to do is believe.    The pesky creationists spoil this phantasmagoric vision.  They’re shaking the bed of the dreaming scientists, shouting “Wake up!  Wake up!  You’re late for work!”  No wonder they are so despised.(Visited 11 times, 1 visits today)FacebookTwitterPinterestSave分享0last_img read more

Fall herbicide applications

first_imgShare Facebook Twitter Google + LinkedIn Pinterest As populations of herbicide resistant weeds continue to grow, sound management practices are more critical than ever to keep these weeds under control. Fall herbicide applications are good tool for controlling existing weeds after harvest, which will provide a weed free field in early spring the following year.According to Mark Loux, OSU Weed Specialist, “Even where the herbicides lack residual, the fall treatment seems to enable more effective control of marestail the following season. In some cases, it’s probable that you don’t even know how much the fall treatment helps out, but our research shows that more often than not it does.”University research also suggests that most fall applied herbicides provide minimal residual control in the spring and that the greatest benefit from residual herbicides is gained from a spring application. The timing of fall herbicide applications is important to ensure control of existing weeds.“In our research, herbicides seem to be effective for control of winter annuals and biennials well into December. The rate of plant death can slow considerably, but this is not a problem since weeds just have to die by early spring. Control of perennials typically declines in late November or early December though, depending upon weather,” writes Loux.University experts have published several excellent articles on this subject that go into great detail, all of which are available online. Below are some effective fall herbicide treatments recommended by Ohio State University research. Keep in mind; it is important to make application decisions based on the weeds present and the crop to be planted the following spring.Any Crop Next Spring: -Glyphosate + 2,4-DSoybeans next spring: Canopy EX or DF + 2,4-D Glyphosate + 2,4-D Metribuzin + 2,4-D (excluding dandelions)Corn next spring: Basis + 2,4-D Glyphosate + 2,4-D Simazine + 2,4-D (except dandelion)For more information about fall weed control check out these articles from Purdue and Ohio State.last_img read more

Humanoid robot supports emergency response teams

The WALK-MAN robot is now at its final validation phase. The project also involved the University of Pisa in Italy, the École Polytechnique Fédérale de Lausanne (EPFL) in Switzerland, the Karlsruhe Institute of Technology (KIT) in Germany and the Université Catholique de Louvain (UCL) in Belgium. The partners contributed to locomotion control, perception capability, affordances and motion planning, simulation tools and manipulation control.The validation scenario was defined in collaboration with the Italian civil protection body in Florence, which participated in the project in an advisory capacity. During the final test, WALK-MAN dealt with a scenario representing an industrial plant damaged by an earthquake where gas leaks and fire were present, a dangerous situation for humans. The scenario was recreated in IIT laboratories, where the robot was able to navigate through a damaged room and perform four specific tasks: opening and traversing the door to enter the zone; locating the valve controlling the gas leakage and closing it; removing debris in its path; and identifying the fire and activating a fire extinguisher.The robot is controlled by a human operator through a virtual interface and a sensorized suit, like Tony Stark in Iron Man. The operator guides the robot from a station located remotely from the accident site, receiving images and other information from the robot’s perception systems.The first version of WALK-MAN was released in 2015, but researchers wanted to introduce new materials and optimize the design to reduce fabrication costs and improve performance. The new version of WALK-MAN has a lighter upper body, which took six months to develop, involving a team of about 10 people coordinated by Nikolaos Tsagarakis, researcher at IIT and coordinator of the WALK-MAN project. The importance of iCub as a standard robotic research platform for embodied AI Citation: Humanoid robot supports emergency response teams (2018, February 23) retrieved 18 July 2019 from https://phys.org/news/2018-02-humanoid-robot-emergency-response-teams.html Researchers at IIT-Istituto Italiano di Tecnologia tested a new version of the WALK-MAN humanoid robot for supporting emergency response teams in fires. The robot is able to locate the fire and walk toward it, and then activate an extinguisher. During the operation, it collects images and transmits them back to emergency teams, who can evaluate the situation and guide the robot remotely. The new WALK-MAN design has a lighter upper body and new hands in order to reduce construction cost and improve performance. The WALK-MAN robot is a humanoid robot 1.85 meters tall, made of lightweight metals, iron and plastics. The robot is controlled remotely by a human operator through a virtual interface and a sensorized suit, which permits to operate the robot very naturally, like an avatar.

The robot is also able to activate an extinguisher to eliminate the fire. Credit: IIT-Istituto Italiano di Tecnologia The lighter upper body is made of magnesium alloys and composite structures, and it is powered by a new version of lightweight soft actuators. Its performance has been improved, with a higher payload (10 kg/arm) than the original one (7 kg/arm); thus, it can carry heavy objects for more than 10 minutes.The new upper body is also more compact in size (62 cm shoulder width, 31 cm torso depth), giving to the robot great flexibility to pass through standard doors and narrow passages.The hands are a new version of Soft-Hand developed by Centro Ricerche E. Piaggio of University of Pisa (group of Prof. A. Bicchi) in collaboration with IIT. They incorporate composite material for the fingers, and have a more human-like finger-to-palm size ratio that allows WALK-MAN to grasp a variety of object shapes. Despite their weight reduction, the hands have the same strength as the original version, with similar versatility in handling and physical robustness.WALK-MAN body is controlled by 32 engines and control boards, four force and torque sensors at hands and feet, and two accelerometers for controlling its balance. Its joints show elastic movement allowing the robot to be compliant and have safe interactions with humans and the environment. Its software architecture is based on XBotCore framework, YARP platform, ROS e Gazebo. The robot head has cameras, a 3-D laser scanner, and microphone sensors. In the future, it can be also equipped with chemical sensors for detecting toxic agents. The new WALK-MAN is a humanoid robot 1.85 meters tall made of lightweight materials, including Ergal (60 percent), magnesium alloys (25 percent) and titanium, iron and plastics. Researchers reduced its weight from the prototype’s 133 kilos to 102 kilos, making the robot more dynamic. The legs can move faster, having a lighter upper body mass to carry. The higher dynamic performance allows the robot to react faster with its legs, maintaining its balance under the effect of physical interaction disturbances—this is very important to adapt its pace to rough terrain and variable interaction scenarios. The lighter upper-body also reduces its energy consumption and the WALK-MAN can operate with a smaller battery (1 kWh) for about two hours. This document is subject to copyright.
