Change of opponent for Theophane

first_imgKilburn’s Ashley Theophane will defend his British light-welterweight crown against Darren Hamilton on Saturday after Steve Williams pulled out of his scheduled title challenge.Hamilton has stepped in to face Theophane at the Aintree Equestrian Centre in Liverpool following Williams’ withdrawal with a chest infection.The fight will be on the undercard of the British heavyweight clash between David Price and Sam Sexton.It will be Theophane’s third defence of the belt he took from Lenny Daws last year, meaning a victory would see him keep the coveted Lonsdale belt outright and remain on course for a possible world title shot.It will be his first fight since he recovered from a torrid start to overcome Ben Murphy with an 11th-round stoppage in December.Bristolian Hamilton, 33, has won 11 of his 13 professional contests – three by knockout.Follow West London Sport on TwitterFind us on Facebooklast_img read more

Cells Teach Humans About Design

first_imgBiomimetics extends to the cellular level, where extraordinary processes show engineers the right way to do things.Locks and keys. We all know man-made locks on our doors, but cells use lock-and-key mechanisms to regulate their own processes. Phys.org says that “Copying nature’s lock-and-key system could improve rapid medical diagnostics.” Researchers at Imperial College London looked at the secrets of receptors on proteins to fashion a new kind of transistor.Receptors recognise molecules with particular shapes and bind to them in a lock-and-key mechanism. In this study, the nanoscale transistor was made from a polymer material that could be imprinted with a binding site – ‘the lock’. This allows the system to detect the only matching ‘key’ – a specific target molecule.To test that the system works as expected, the team used it to detect the antibody that binds to insulin, a mechanism important in the diagnosis of diabetes. However, the team say that the system design can also be readily applied in the detection to a much broader range of biological molecules.Co-author of the study Professor Joshua Edel, from the Department of Chemistry at Imperial, said: “We have shown that we can imprint a polymer at the entrance to the nanopore with the shape of the natural ‘lock’ to the ‘key’ molecule we are looking for, mimicking biological receptors.“What’s a ‘photonic melanin supraball’? Whatever it is, it must be good, because it was the product of ‘bioinspiration’ to a team desiring to mimic structural colors – those ‘photonic crystals’ that give butterflies their iridescent wings and birds their flashing feathers. To achieve their design, they looked to the molecular components behind those animal wonders:We demonstrate a feasible solution for producing structural colors inspired by bird feathers. We have designed core-shell nanoparticles using high–refractive index (RI) (~1.74) melanin cores and low-RI (~1.45) silica shells. The design of these nanoparticles was guided by finite-difference time-domain simulations. These nanoparticles were self-assembled using a one-pot reverse emulsion process, which resulted in bright and noniridescent supraballs. With the combination of only two ingredients, synthetic melanin and silica, we can generate a full spectrum of colors. These supraballs could be directly added to paints, plastics, and coatings and also used as ultraviolet-resistant inks or cosmetics.Think of the lipstick shades that could come from this technology. Even pigs might look charming with it.Selective passage for smart membranes. Cell membranes have the amazing capacity to let certain items in and block others. Called active transport, this capacity (unlike unguided osmosis, a natural law that only follows the concentration gradient), allows cells to use natural law to ‘violate’ natural law by design, going against natural concentration gradients through the use of highly-sophisticated ‘gates’ in the membrane. One of those is the aquaporin family of membrane channels, which let water in or out but can block other molecules. Nature Scientific Reports published a new paper about this, “Quantification of Aquaporin-Z reconstituted into vesicles for biomimetic membrane fabrication.” This is important, they say, because “Aquaporin incorporated biomimetic membranes are anticipated to offer unprecedented desalination capabilities” such as reverse osmosis.Quantifying the reconstituted aquaporins in synthetic membranes, however, represents a “huge hurdle” to progress in this field. The team in Singapore came up with a new method to determine how many channels make it into production:These methods allow more accurate determination of Aquaporin-Z reconstituted and loss during reconstitution, with relatively commonly available equipment and without complex sample handling, or lengthy data analysis. These would allow them to be widely applicable to scientific studies of protein function in the biomimetic environment and engineering studies on biomimetic membrane fabrication.In this series of three CEH articles, we have shown that biomimetics is still a very hot topic in science. Engineers are getting inspired everywhere in nature: from animals, from plants, and even from the tiny molecular machines in cells.Go bioneers! (5/13/06). In the 15 years we have been reporting on progress in biomimetics, interest in the subject has grown steadily around the world. The time is ripe to oust the Darwin Party totalitarian regime and send them into exile. Design is the word for the 21st century!

US publisher buys rights to young South African’s tale

first_img21 January 2015The international rights to youth activist Malaika wa Azania’s book, Memoirs of a Born Free: Reflections on the Rainbow Nation, have been bought by Seven Stories Press, a US publisher based in New York.In making their offer, Dan Simon, publisher at Seven Stories Press, compared Wa Azania to “a young Steve Biko, someone I have long revered for the directness and clarity and power of his vision and his words”, Jacana Media, Wa Azania’s South African publisher, said in an undated media release.The Press plans to publish the book in the US this year “and will be seeking further international publishing opportunities in the new year for the young firebrand”, Jacana said.Memoirs of a Born Free as Wa Azania’s “long-overdue letter to the ANC” as well as “a journey of the extraordinary life that she has lived”, Jacana said.According to BooksLive, Malaika wa Azania is the pen name of 23-year-old Malaika Lesego Samora Mahlatsi, described as a “fierce debater and an activist devoted to pursuing the African Renaissance agenda”.Her book recounts her experience of growing up in Meadowlands, Soweto, through the end of apartheid and during South Africa’s transition to democracy. Along the way, she develops her Pan-Africanist ideals and identifies herself as a “fighter and future custodian for blackness”.Wa Azania has said she rejects the notion of “born frees”: “Even in the book I speak about how I feel the term born free is a false thesis,” she says in a video interview with Polity.co.za. “The entire narrative around what born frees are is itself a false thesis. I don’t believe there is such a group of people called born frees.”The 23-year-old author told TimesLive that the US deal would help her continue to provide for her family and pay her fees at Rhodes University in Grahamstown, where she is a student.“I am the breadwinner at home after my mother was retrenched.”Wa Azania’s story is not a reflection of the freedom spoken about in the romantic speeches of government officials, Jacana says. “It epitomises the ongoing struggle for liberation and for emancipation from the mental slavery that still exists even in the ‘born-free’ generation.”SAinfo reporterlast_img read more

A charcoal scrub for drinking water

first_imgShare Facebook Twitter Google + LinkedIn Pinterest It’s just the twist of a handle away when we want to take a shower or make that first pot of coffee in the morning. But behind the scenes at the local water plant, water treatment professionals are hard at work to make sure that water is safe to use, and especially safe to drink.They use all kinds of technologies to do their work, but one of their most common tools is activated carbon (sometimes called activated charcoal). When it’s mixed into the water, it adsorbs organic contamination and compounds that create taste or smell problems in tap water supplies. In drinking water drawn from Lake Erie, one of its jobs is to remove toxins created by harmful algal blooms, such as microcystins and saxitoxins.The difficult part for treatment plant staff is knowing exactly how much activated carbon to use, because its effectiveness depends on many different factors, from toxin levels and the type of activated carbon they have on hand to whether the raw water has plants or lots of sediment in it. So they prefer to be safe, possibly using more activated carbon than necessary and raising treatment costs by hundreds of dollars each day for as long as an algal bloom is present near their water intake.Dr. John Lenhart, an associate professor in the Department of Civil, Environmental and Geodetic Engineering at The Ohio State University, and his research team are now working on guidelines that address some of these issues, using both powdered and granular activated carbon made from wood, coconut shells, bituminous coal and a coal blend. Powdered products are used on an as-needed basis, while granular activated carbon is built into the overall treatment process when a particular plant tends to have chronic issues to address.How much microcystin toxin granular activated carbon can adsorb depends on what the carbon is made from, and whether the water is clear (blue bars) or contains organic matter like decomposing plants (orange bars). Results from test solutions that model the water typically going through an Ohio treatment plant show that organic matter reduces the amount of adsorbed microcystin and needs to be addressed during water treatment. Adsorption capacity is defined as milligrams (mg) of microcystin removed per gram (g) of activated carbon added.The research is funded by the Ohio Department of Higher Education’s Harmful Algal Bloom Research Initiative (HABRI), a statewide response to the threat of harmful algal blooms that arose out of the 2014 Toledo drinking water crisis, where elevated levels of algal toxins in Lake Erie shut down water supplies for half a million people in northwest Ohio. Lenhart recently received funding for a third project focusing on saxitoxin removal (completing in 2020), adding to the team’s work on microcystin toxins (completed in 2016) and granular vs. powdered activated carbon products (completing in mid-2018).Highlights from the previous projects suggest that wood-based powdered activated charcoal is the best choice for removing microcystins, especially because it interacts with the toxin and any organic matter in the water more quickly than coal-based activated carbon. Coconut-based powdered activated carbon, a common choice in water pitcher filters, was a poor option for removing microcystin. Granular activated carbon followed similar trends during initial laboratory tests.The scientists also saw that natural organic matter like decomposing plant material can decrease the amount of toxin removed (see graph). They are currently running experiments at a larger scale, in columns similar to those used in treatment plants.“Our partners include water treatment plants in Wilmington and Barberton that face issues related to harmful algal blooms and saxitoxins, and that will directly benefit from the results of this research,” said Lenhart. “Our continued goal is safe drinking water for communities and money savings for water plants that will be able to apply activated carbon in a more targeted fashion.”last_img read more

Running: The health mantra for Delhi

In fact, the capital offers its residents everything they may need for a healthy life. The excellent infrastructure it provides is enough for us to be proud,Naveen JindalDelhi is an intoxicating mix of traditional and modern blends and is ideal for anyone who is passionate about sports and fitness. In fact, the capital offers its residents everything they may need for a healthy life. The excellent infrastructure it provides is enough for us to be proud of.Far removed from the glass and chrome cities world over, Delhi abounds in greenery and has parks and stadiums that are tailor-made for the fitness conscious. While exercise is a personal regimen, running in this city has taken on social proportions. The first time I ran in a marathon was three years ago; the energy of a thousand people running together was just amazing, and addictive. City marathons create a sense of belonging, a sense of ownership and responsibility. While maintaining the highest level of fitness is my primary aim, running the marathon is an unparalleled experience. The Delhi Marathon is always for a good cause and I love knowing that we are helping a cause by running as a community.Another event that I take pride in being part of is the Tiranga Run. To run holding the national flag high is a feeling every Indian should be able to boast of. I take a personal pride in this as it was when I moved a plea that the Court allowed every Indian national the right to fly the national flag.When I first ran the Delhi marathon three years ago, I found the energy of a thousand people running together amazing, and addictiv.Of course, running a marathon is serious exercise, and fitness is something every individual should take seriously. I personally have not been jogging outdoors regularly of late but this city has a plethora of excellent options for those who love running. Lodhi Gardens, Nehru Park, India Gate, professional stadiums and even private clubs, the capital offers some thing to anyone brimming with enthusiasm. Over the past few years, time constraints have meant that I work out mostly at home. But I always believe that a healthy body is the key to a positive mind and thus for me, a fitness regimen is a must. I am also a firm believer in the benefits of yoga and pranayam. Yoga is as much about the body as it is about the mind and I religiously practise my daily routine of yoga even when I am travelling.What is important is to have a healthy lifestyle and by that I mean early to bed and early to rise, exercise daily, and eat the right food at regular intervals, which helps maintain metabolism. If you eat unhealthy or junk food, then it becomes very difficult to burn out the calories. One has to be disciplined, always.advertisementThe best tracks in townSIRI FORT SPORTS COMPLEXKhel Gaon MargTrack: 1 kmSurface: Clay lawn surface for a smooth run.
