Students mother chicks – Shelby Star

Elise Franco Senior reporter efranco_star

For 21 days, students at Springmore Elementary gained hands-on experience caring for chicken eggs as a lesson in life cycles.

Wendy Turbyfill, youth development agent with 4-H of Cleveland County, said 4-H organized a school enrichment program and worked with Case Farms to have 125 eggs donated for use in five second-grade classrooms.

"The classes were studying life cycles, and embryology fit perfectly with this program," she said.

Second-grade teacher Anna Ramsey said the program not only taught students about life cycles, but also about responsibility.

"The kids were in charge of turning the eggs three times per day for 21 days in order for them to hatch," she said. "They were so excited, and they got so motherly, even the boys."

On Thursday, 4-H staff, along with Springmore students and teachers, wrapped up the project with a "chick birthday bash" to celebrate the hatching of 96 of the 125 eggs.

"You could ask any of the kids a question about the life cycle now, and they'll all be able to tell you about it," Ramsey said. "We love that they got the hands-on experience and got to take part in it."

Turbyfill said that hands-on learning is the reason why 4-H hosts these type of programs.

"They'd never understand how embryology works the way they do now," she said. "Hopefully it's something they'll always remember."

Turbyfill said 4-H has also worked this year with students at Bethware and Washington elementary schools. She said the goal is to eventually host the program in every second-grade class in Cleveland County.

Fertility clinics selling ‘ineffective’ IVF add-ons – International Federation of Gynecology and Obstetrics

A fertility watchdog has warned that women paying for IVF treatment are being pressured to pay for additional products. The Human Fertilisation and Embryology Authority has said that clinics are selling unneeded add-ons, but it is unable to prevent this.

Extra treatments being offered to women include drugs to prevent rejection, screening to choose the best embryo and procedures to result in better implantation. IVF treatment costs around 4,000 per course and these add-ons can cost between 100 and 3,500.

However, many of these treatments are ineffective, meaning clinics are getting women's hopes up about having a better chance of the process working. Oxford University research that was presented on BBC's Panorama at the end of last year showed that just one of the 27 treatments had any effect.

Sally Cheshire, chairof the Human Fertilisation and Embryology Authority, told a fertility conference in central London on March 29th that clinics offering these add-ons put more pressure on women who are already experiencing a lot of stress.

She said that the authority is concerned about the use of add-on treatments, but it cannot stop clinics from offering them or control the pricing.

Professor Adam Balen, chairman of the British Fertility Society, also spoke at the conference. He highlighted the fact that there is confusion for women over what is an actual add-on as many treatments that are being sold as add-ons are actually part of standard treatments, causing more confusion.

The Efficient Beauty of Starfish Larvae – Bay Nature

In the summer of 2015 three Stanford scientists took a class in embryology at Hopkins Marine Station in Pacific Grove and found themselves transfixed by a bat star larva that moved water around itself in swirling patterns. Using a microscope with video capacity, the scientists could see vortices of water slowly rotating, merging, and splitting apart around the millimeter-long larva.

We were totally surprised, says Vivek Prakash, a bioengineering postdoctoral scholar. They were so beautiful, and we were never expecting to see a really complex pattern of fluid flow around the starfish larvae, so that really got us hooked.

As the baby starfish waves its ciliathe small hairlike structures covering its bodythe water begins to swirl. The linear bands of cilia drape around its body like necklaces; its a common structure found across various types of aquatic invertebrate larvae.

But, the researchers wondered, Why would it be that all of these animals develop the same structure, this sort of way of stirring the water with these cilia? William Gilpin, an applied physics graduate student, recalls. By looking at the fluid dynamics, we think that we have an idea. Gilpin, Prakash, and bioengineering assistant professor Manu Prakash (no relation) detailed a potential evolutionary explanation in the December 2016 issue of Nature Physics.

The first two months of a bat stars life are spent floating through the ocean, constantly alternating between feeding and moving. And as the researchers found through observation and mathematical modeling, the ciliary bands are an ideal structure for maximizing the larvaes ability to do both. Algae particles pulled into the vortices swirl toward the larvas body, and once a particle touches the body, the cilia move it toward the larvas mouth. Meanwhile, the vortices also propel the tiny larvae through the ocean.

In their study, Gilpin, Prakash, and Prakash observed that the ciliary bands changed the patterns of vortices depending on the density of algae in the water around the larvae. If a larva sensed an abundance of food, then the ciliary bands could create more vortices to trap the food, while in lower-nutrient areas the ciliary bands would decrease the number of vortices for more efficient movement.

The complex dual-purpose action hadnt been observed before, Gilpin says. The starfish have found a new trick that we didnt know about; it was hiding right beneath our noses the entire time. Its always exciting to see that nature has found a solution that we havent.

After their larval stage, bat stars grow to an average diameter of eight inches and can be found in Bay Area tide pools.

Family pay tribute to student who died in Derby Road crash – Nottingham Post

Comments(0)

The family of a 20-year-old student who died after he was hit by a car in Lenton have paid tribute to their 'fun-loving' son.

Andrew Robertson, of Berkshire, died at the scene of the crash on Derby Road at around 4.45pm last Thursday (March 30).

He was in his second year studying biochemistry at the University of Nottingham.

A statement from his family said: "He had a bright future ahead of him. He was a loving son, grandson, brother, nephew, cousin and boyfriend.

"He had many friends both at university and at home. Words cannot express how much he will be missed and we are extremely saddened by his death.

"Andrew was caring, fun-loving, sociable, supportive and very easy-going. He was a team player who always kept his word and looked out for others.

"We would appreciate privacy during this difficult time to allow us to grieve and come to terms with our loss."

Police are investigating and are appealing to anyone who might have seen anything in the area around the time of the collision, which happened between Clifton Boulevard and Priory Island.

Officers are particularly keen to speak to drivers with dashcam footage.

Hundreds of motorists were caught in gridlocked traffic after the incident occurred.

Retired Michael Fisher, who lives in Charles Avenue, said he was not surprised to hear that an incident had occurred on what he describes as a "dangerous road."

The 64-year-old told the Post: "That is sad to hear. It is a very busy road and I won't cross it without pressing the button.

"It does not surprise me at all but it is a shame."

A large section of the road was cordoned off for several hours while investigations were carried out at the scene.

Science Day brings students to campus – The Dartmouth

by Mika Jehoon Lee | 4/4/17 2:15am

Students from local schools with an interest in science read weather maps, planted seedlings and examined sheep brain specimens at the fifth annual Science Day held this past Saturday, April 1 at various labs on campus.

According to fourth-year biochemistry graduate student and Science Day co-organizer Jessica DeSimone, this years attendance was the highest since its launch in 2013. A total of 171 adults accompanied 231 students at the event this year. DeSimone said that close to 200 adults and 300 students RSVPd for the event, but inclement weather may have accounted for the gap between expected and actual attendance.

Science Day is a free, drop-in event that features 15-minute long scientific demonstrations and hands-on activities geared toward students in sixth to ninth grade. According to DeSimone, Science Day was created to educate local community members about science and foster students passion for the subject. DeSimone said that Science Day was hosted by the group Graduate Women in Science and Engineering over the past few years, but this year it was independently organized by DeSimone, sixth-year biochemistry student Kelly Salmon and second-year biochemistry student Sarah Valles due to leadership changes in the group. They received funding for this years event from the School of Graduate and Advanced Studies. In addition to the three organizers, around 60 graduate students from eight different departments including biology, chemistry and psychology prepared 11 total activity stations for the event this year.

In the under the microscope station, students watched worms and flies glow under microscopes. According to third-year cellular and molecular biology graduate student Timothy Gauvin, a volunteer at the station, worms and flies provide a simple system for studying various human diseases, because the three species share a lot of similarities. Gauvin added that his love for microscopes got him interested in science and that he hoped students exposure to the activity would inspire their passion for science.

I thought it was cool to look at human cells under [microscopes] and as I investigated further, there was a lot of cool stuff you could do with this, Gauvin said. Im hoping kids of various ages can see that we have a lot of cool tricks.

Local middle school student Hope Cooper, who visited the under the microscope station, said that she enjoyed looking at worms under the microscope and learning about how worms hatch. Both Cooper and her father Adam Cooper attended Science Day two years ago and said that there were more microscopes and opportunities for students to use them this year than in years past.

Adam Cooper spoke highly of the benefit of such an event for students in exposing them to subjects they might study or pursue in the future.

The exposure for our kids to see what interests they may or may not have, to be able to see what they might want to do when they grow up and what they might not want to do when they grow up, [is] just a lot of good exposure to what their future might be, Adam Cooper said.

Meanwhile, in the soil and the world beneath our feet station, volunteers including ecology, evolution, ecosystems and society graduate student Ashley Lang Gr20 helped kids learn about mycorrhizal fungi and fossils. Lang said she wanted to introduce students to mycorrhizae, which grow in symbiotic relationships with plants, because it is poorly understood and many people are unaware of its existence.

Local elementary school student Nicholas Champine said that he enjoyed participating in Langs station and appreciated learning about fungis influence on plant growth.

Local elementary school student Charleigh Olmstead said that he specifically enjoyed playing the game Jet Stream Racer in the flowing rivers of air station. According to earth science graduate student Huanping Huang, the game allows students to become pilots and learn more about jet streams and gas. Jag Olmstead, Charleighs father, said that Science Day provided an opportunity of intellectual engagement for his children, as opposed to more typical recreational activities.

[Science Day] is something for the kids to enlighten their minds, learn something new and not play video games, Jag Olmstead said.

Rong Ding, whose elementary school-aged son participated in the flowing rivers of air station, said that the event provided his son with a unique opportunity to witness and participate in scientific experiments, which is not an everyday occurrence.

Science Day attendees were also given tours of the Thayer School of Engineering, where they visited the schools laboratories and made flubber, a rubbery polymer.

Anatomy of a fake scandal, ginned up by right-wing media and Trump – Washington Post (blog)

President Trump started off this morning as he often does, by settling in to watch the festival of nincompoopery that is Fox & Friends. On the show, he saw something that he believes vindicates the bizarre and false charge he made that Barack Obama was tapping his phones during the presidential campaign.

Ill try to sort through the substance of all this. But I also want to make a broader argument about how Trumps support system inside his government but especially in the conservative media and on Fox, which is where he apparently gets most of his intelligence information is playing to his worst instincts, harming him politically, and making his presidency even more dangerous.

Todays antics all started with a report on Fox & Friends in which correspondent Adam Housley reported that a high-ranking Obama administration official had requested the unmasking of the names of Trump officials who were caught up in surveillance of foreign targets. Ordinarily, when a U.S. person shows up in such surveillance say, talking to a Russian ambassador whose communications are being monitored that persons identity is blacked out in reports on the surveillance. While Housley did not identify the Obama administration official, he did say that Trump associates were being picked up by this surveillance for a year before Trump took office.

Then we get this report from Eli Lake, identifying former national security adviser Susan Rice as the Obama official who requested the unmasking. Id like to highlight this passage:

Rices requests to unmask the names of Trump transition officials does not vindicate Trumps own tweets from March 4 in which he accused Obama of illegally tapping Trump Tower. There remains no evidence to support that claim.

But Rices multiple requests to learn the identities of Trump officials discussed in intelligence reports during the transition period does highlight a longstanding concern for civil liberties advocates about U.S. surveillance programs. The standard for senior officials to learn the names of U.S. persons incidentally collected is that it must have some foreign intelligence value, a standard that can apply to almost anything. This suggests Rices unmasking requests were likely within the law.

Id say that if members of the Trump team were in communication with foreign actors who were under surveillance, that damn sure has foreign intelligence value, and its not too surprising that the national security adviser would want to know about it. Were talking about associates of a presidential candidate communicating with representatives of a foreign power.

Lets back up for a moment and go through the series of events here to get some context. Heres what has happened, with the caveat that some of the information is sketchy:

1. On March 4, President Trump sends out a series of tweets claiming that Barack Obama tapped his phones, apparently because of an article Trump saw on Breitbart. In subsequent days, the FBI director, the NSA director, the former director of national intelligence and everyone in any position to know make clear that not only didnt Obama tap Trumps phones, the president has no power to order phone-tapping.

White House press secretary Sean Spicer has been repeatedly defending President Trump's unproven claims that former president Barack Obama ordered a wiretap on him in 2016. (Bastien Inzaurralde/The Washington Post)

2.Because Trump never backs down from even the most ridiculous lie, his employees and allies are now required defend his claim. So spokesperson Sean Spicer argues that because in a different tweet Trump put the words wire tapping in quotes, that means he was referring to a whole host of surveillance types and not his phones being tapped, despite the fact that he said President Obama was tapping my phones. Trump himself will later pick up this argument.

3.Two White House officials, Ezra Cohen-Watnick and Michael Ellis, locate intelligence reports that include Trump officials in communication with Russians under surveillance by American intelligence agencies. The White House says they came across those reports in the ordinary course of business and were not actually looking for something that would back up Trumps claim; you can decide how plausible you find that. In any case, they then call Rep. Devin Nunes, the chair of the House Intelligence Committee, to the White House so he can view the information. Nunes then holds a news conference announcing the find and briefs Trump on what Trumps own staff has told him.

All of this was designed to allow Trump to say that he was right all along that he was being targeted by Obama, which of course he does.

4. Im skipping over some smaller developments and plenty of details. But today, we have the following series of events: Trump officials leak that Rice requested the unmasking of the identities of Trump associates who were in communication with foreigners under surveillance; those reporters publish their stories; then the president himself calls attention to them on his Twitter feed:

This particular PR maneuver is not unprecedented, but the point is this: Whats obviously of most importance to the president of the United States isnt the fact that his associates were in contact with people from Russia (or other countries) who were of sufficient interest to U.S. intelligence that they would be under surveillance, but whether or not each new detail that emerges does or does not support his idiotic tweets.

And this is why I argue that Fox and some of Trumps allies are only helping him hurt himself. Much of the time, having a supportive amen chorus has great political utility, because it helps buck up your base and disseminate the arguments youre making. But its one thing when those arguments are things like We should cut taxes or Obamacare is a disaster. Its something else when theyre trying desperately to claim that every stupid thing Trump ever said is actually true.

In this case, clinging to the idea that the Obama administration unfairly monitored the Trump campaign only encourages further investigation of what could turn out to be one of the biggest scandals in American political history. Nuness buffoonish efforts on Trumps behalf havent helped him at all. Quite the contrary, theyve made his committee utterly irrelevant and increased pressure on the Senate Intelligence Committee to conduct a thorough and objective review. Nunes has zero credibility, and so he can no longer be an asset to the White House.

But when Trump tunes in to Fox & Friends every morning, he learns that hes right about everything. He doesnt need to listen to his intelligence briefers or anyone else who might tell him something he doesnt want to hear. He can keep telling tall tales and pursuing his petty grievances. He never does anything wrong and never has to change. I shudder to think how that dynamic will play out when this administration faces its first foreign policy crisis, with untold numbers of lives at stake.

Capcom reveals the 20-year-old guide it still uses today.

By Wesley Yin-Poole Published 04/04/2017

Capcom has published scans of a 20-year-old guide it still uses today when creating Street Fighter characters.

That's Demitri Maximoff from Darkstalkers on the cover.

At GDC last month, Capcom's Toshiyuki Kamei delivered a talk on the art direction of Street Fighter 5. As part of it, he discussed Anatomy: A Strange Guide for Artists, a document created 20 years ago around the time Darkstalkers was being made.

This document was edited by legendary Capcom artist Akira "Akiman" Yasuda, who intended for it to help teach the company's artists the rules of exaggerated anatomical features to be followed when making cool-looking pixel art.

Now, Capcom has published scans of the guide on its website, and while the accompanying text is in Japanese, we still get a decent idea of what Anatomy: A Strange Guide for Artists is all about.

The cover shows Demitri from the Darkstalkers series, and inside we see figure drawings similar to the style of Andrew Loomis, the American illustrator, alongside notes.

"It explains shortcuts and rules about how we take musculature and a character's frame and make a sprite out of it," Kamei explained during his GDC talk.

"If you exaggerate this part of the musculature it looks cool, or if you make this part slimmer it can be more efficient in the visual language. There are a lot of different rules.

"Even though this is over 20 years old, having this information about what's important and not important is still used today."

Kamei revealed an example of how this guide was used in the creation of Street Fighter 5 characters.

"When you're looking at an arm from the front, the rule is the upper arm should be thinner than the lower arm," he explained. "But when looking at it from the side, that same arm should look narrow in the forearm and wider for the upper arm.

"By following this one rule you can convey a lot of information about how this character is extending their arm, whether they're doing a straight punch or an uppercut in a really short amount of time."

Capcom created a Street Fighter 5 prototype that used photo-realistic visuals and realistic proportions, but found it made the game harder to play, so it stuck with a more exaggerated style for the game.

It's really cool to see scans of Anatomy: A Strange Guide for Artists, and get a peek behind the curtain of how Capcom's fighting games are made. Credit to Akiman, then, for his early days work on establishing the rules that would help in the creation of fighting games for the next 20 years.

Michelangelo’s Medici Chapel may contain hidden symbols of … – Phys.Org

April 4, 2017 Highlight showing the sides of the tombs containing the bull/ram skulls, spheres/circles linked by cords and the shell (A). Note the similarity of the skull and horns to the uterus and fallopian tubes, respectively (B). The shell contained in image A clearly resembles the shell contained in Sandro Botticelli's "The Birth of Venus" (1483), Galleria degli Uffizi, Florence, Italy (C). Image B of the uterus and adnexa from Netter's Atlas of Human Anatomy with permission Philadelphia: Elsevier. Credit: Clinical Anatomy

Michelangelo often surreptitiously inserted pagan symbols into his works of art, many of them possibly associated with anatomical representations. A new analysis suggests that Michelangelo may have concealed symbols associated with female anatomy within his famous work in the Medici Chapel.

For example, the sides of tombs in the chapel depict bull/ram skulls and horns with similarity to the uterus and fallopian tubes, respectively.

Numerous studies have offered interpretations of the link between anatomical figures and hidden symbols in works of art not only by Michelangelo but also by other Renaissance artists.

"This study provides a previously unavailable interpretation of one of Michelangelo's major works, and will certainly interest those who are passionate about the history of anatomy," said Dr. Deivis de Campos, lead author of the Clinical Anatomy article. Another recent analysis by Dr. de Campos and his colleagues revealed similar hidden symbols in Michelangelo's Sistine Chapel.
