cold-blooded animals are very sensitive to temperature, so it makes sense that over the course of evolution, this primordial mechanism could have been modified in warm-blooded animals," he said. In the current study, the researchers focused on cultured mouse cells and tissues, and found that genes related to circadian functions were controlled by temperature fluctuations. SCN cells were not temperature-sensitive, |
however. This finding makes sense, Dr. Takahashi said, because if the SCN, as the master control mechanism, responded to temperature cues, a disruptive feedback loop could result, he said. Explore further: Now we know why old scizophrenia medicine works on antibiotics-resistant bacteria |
If superparticles were to exist the decay would happen far more often. This test is one of the "golden" tests for supersymmetry and it is one that on the face of it this hugely popular theory among physicists has failed. Prof Val Gibson, leader of the Cambridge LHCb team, said that the new result was "putting our supersymmetry theory colleagues in a spin". The |
results are in fact completely in line with what one would expect from the Standard Model. There is already concern that the LHCb's sister detectors might have expected to have detected superparticles by now, yet none have been found so far.This certainly does not rule out SUSY, but it is getting to the same level as cold fusion if positive experimental result does not |
When the world was still young, some 3 500 million years ago, molten rock forced its way through the earth's crust and solidified to form the spectacular granite outcrops where |
Pretoriuskop Rest Camp is now nestled. The impressive granite dome known as "Shabeni Hill" is not far from the camp, which is found in the south-western corner of the Kruger |
National Park. It is immediately apparent to any visitor that Pretoriuskop is unique as brilliant red trees adorn the camp, pre-dating the decision to make exclusive use of indigenous plants |
in laying out rest camp gardens. Nostalgia prompted an exception to the rule for Pretoriuskop, the Kruger National Park's oldest rest camp, and exotic flowering plants were allowed to stay, |

Hibiscus rosa-sinensis 'The Path' Chinese Hibiscus, Tropical Hibiscus Among the showiest flowering plants. Plants typically bear funnel-shaped blossoms, often with prominent stamens. The many species offer a wide range of |
flower colors. Probably from tropical Asia; tropical hibiscus has been in cultivation for centuries, and is among the most flamboyant flowering shrubs. It reaches 30 ft. tall and 15 to |
20 ft. wide in Hawaii, but more typical size on mainland is 8 to 15 ft. tall, 5 to 8 ft. wide. Glossy leaves vary somewhat in size and texture |
depending on variety. Growth habit may be dense and dwarfish or loose and open. Summer flowers are single or double, 4 to 8 in. wide. Colors range from white through |
pink to red, from yellow and apricot to orange. Individual flowers last only a day, but the plant blooms continuously. Provide overhead protection where winter lows frequently drop below 30°F/-1°C. |
Where temperatures go much lower, grow in containers and shelter indoors over winter; or treat as annual, setting out fresh plants each spring. Hibiscus also makes a good houseplant. This |
shrub requires excellent drainage; if necessary, improve soil for best drainage or set plants in raised beds or containers. Can be used as screen, espalier, or specimen. To develop good |
branch structure, prune poorly shaped young plants when you set them out in spring. To keep a mature plant growing vigorously, prune out about a third of old wood in |
early spring. Pinching out tips of stems in spring and summer increases flower production.All varieties susceptible to aphids. There are thousands of selections.'The Path' Gorgeous, ruffled, single, buttercup yellow flowers |
with a bright pink center on a bushy, upright shrub that grows 6–8 ft. tall, 4–5 ft. wide. Large, frilly, single, bright orange flowers with white central eye edged in |
red. Strong-growing, erec... Double golden flowers with petals that shade to carmine orange toward base. Plant is bushy and upright... This 6–8 ft.-tall variety has big, single, soft pink flowers. |
Outside of the academic environment, a harsh and seemingly ever-growing debate has appeared, concerning how mass media distorts the political agenda. Few would argue with the notion that the institutions of the mass media are important to contemporary politics. In the transition to liberal democratic politics in the Soviet Union and Eastern Europe the media was a key battleground. In the West, elections increasingly |
focus around television, with the emphasis on spin and marketing. Democratic politics places emphasis on the mass media as a site for democratic demand and the formation of “public opinion”. The media are seen to empower citizens, and subject government to restraint and redress. Yet the media are not just neutral observers but are political actors themselves. The interaction of mass communication and political |
actors — politicians, interest groups, strategists, and others who play important roles — in the political process is apparent. Under this framework, the American political arena can be characterized as a dynamic environment in which communication, particularly journalism in all its forms, substantially influences and is influenced by it. According to the theory of democracy, people rule. The pluralism of different political parties provides |
the people with “alternatives,” and if and when one party loses their confidence, they can support another. The democratic principle of “government of the people, by the people, and for the people” would be nice if it were all so simple. But in a medium-to-large modern state things are not quite like that. Today, several elements contribute to the shaping of the public’s political |
discourse, including the goals and success of public relations and advertising strategies used by politically engaged individuals and the rising influence of new media technologies such as the Internet. A naive assumption of liberal democracy is that citizens have adequate knowledge of political events. But how do citizens acquire the information and knowledge necessary for them to use their votes other than by blind |
guesswork? They cannot possibly witness everything that is happening on the national scene, still less at the level of world events. The vast majority are not students of politics. They don’t really know what is happening, and even if they did they would need guidance as to how to interpret what they knew. Since the early twentieth century this has been fulfilled through the |
mass media. Few today in United States can say that they do not have access to at least one form of the mass media, yet political knowledge is remarkably low. Although political information is available through the proliferation of mass media, different critics support that events are shaped and packaged, frames are constructed by politicians and news casters, and ownership influences between political actors |
and the media provide important short hand cues to how to interpret and understand the news. One must not forget another interesting fact about the media. Their political influence extends far beyond newspaper reports and articles of a direct political nature, or television programs connected with current affairs that bear upon politics. In a much more subtle way, they can influence people’s thought patterns |
For many years, UNESCO and China have collaborated closely in the field of world heritage. Among the 35 Chinese properties on the World Heritage List, there are 25 cultural, 6 |
natural and 4 mixed sites. China is working with the countries of Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan) on a Serial World Heritage Nomination of the Silk Roads. |
Like the country itself, China’s intangible cultural heritage is of extremely vast. The Kun Qu Opera was proclaimed a Masterpiece of the Oral and Intangible Heritage of Humanity in 2001, |
and the Guqin and its Music in 2003. The Uyghur Muqam of Xinjiang and the Urtiin Duu – Traditional Folk Long Song (the latter was submitted together with Mongolia) were |
awarded this distinction in 2005. A number of field projects have been devoted to endangered languages. With regard to cultural diversity, the cultural approach to the prevention and treatment of |
HIV and AIDS is being studied by officials. Crafts that make it possible to maintain traditional techniques - frequently the preserve of women - as well as community economic development |
are being promoted in some regions. China also collaborates with UNESCO in the area of dialogue through the programme on Intercultural Dialogue in Central Asia. In the framework of this |
May 16, 2011 If you fuel your truck with biodiesel made from palm oil grown on a patch of cleared rainforest, you could be putting into the atmosphere 10 times |
more greenhouse gasses than if you’d used conventional fossil fuels. It’s a scenario so ugly that, in its worst case, it makes even diesel created from coal (the “coal to |
liquids” fuel dreaded by climate campaigners the world over) look “green.” The biggest factor determining whether or not a biofuel ultimately leads to more greenhouse-gas emissions than conventional fossil fuels |
is the type of land used to grow it, says a new study from researchers at MIT. The carbon released when you clear a patch of rainforest is the reason |
that palm oil grown on that patch of land leads to 55 times the greenhouse-gas emissions of palm oil grown on land that had already been cleared or was not |
located in a rainforest, said the study’s lead author. The solution to this biofuels dilemma is more research. Unlike solar and wind, it’s truly an area in which the world |
The Bible gives us a clear picture of foolish behavior and its consequences. It’s important for us to recognize these traits in others—and in ourselves. Dealing appropriately with people who behave foolishly requires prayer and wisdom. But remember, that foolish person is not in your life by accident, and you |
can by God’s grace respond to him or her in a Christ-like manner. Characteristics of Foolish Behavior 1. Denying, disregarding, or rebelling against God. The fool says in his heart “There is no God” (Psalm 14:1). 2. Slandering, lying, deceiving The one who conceals hatred has lying lips, and whoever |
utters slander is a fool 3. Quick-Tempered A fool shows his annoyance at once, but a prudent man overlooks an insult (Proverbs 12:16). 4. Acts Impetuously and Without Regard for Consequences In everything the prudent acts with knowledge, but a fool flaunts his folly. (Proverbs 13:16). One who is wise |
is cautious and turns away from evil, but a fool is reckless and careless. 5. Talks endlessly, brags, spouts off frequently. A fool takes no pleasure in understanding, but only in expressing his opinion The wise lay up knowledge, but the mouth of a fool brings ruin near. (Proverbs 10:14). |
A fool’s mouth is his ruin, and his lips are a snare to his soul. (Proverbs 18:7 ). 6. Refuses Advice, Accountability and/or Discipline A fool despises his father’s instruction, but whoever heeds reproof is prudent A rebuke goes deeper into a man of understanding than a hundred blows into |
a fool 7. Handles Money Recklessly Of what use is money in the hand of a fool, since he has no desire to get wisdom? In the house of the wise are stores of choice food and oil, but a foolish man devours all he has (Proverbs 21:20). 8. Quarrels |
frequently, picks fights, is contentious Fools get into constant quarrels; they are asking for a beating (Proverbs 18:6 NLT). A fool gives full vent to his anger, but a wise man keeps himself under control 9. Lazy, Lacks Focus and Ambition Foolish people refuse to work and almost starve (Ecclesiastes |
4:5). A wise person thinks much about death, while the fool thinks only about having a good time now (Ecclesiastes 7:4 ). Fools are so exhausted by a little work that they have no strength for even the simplest tasks (Ecclesiastes 10:15 ). 10. Never Learns from Past Experience As |
a do returns to his vomit, so a fool repeats his folly (Proverbs 26:11). You cannot separate fools from their foolishness, even though you grind them like grain with mortar and pestle (Proverbs 27:22 ). How are we to respond to foolish behavior? 1. First and most importantly, we pray |
is not fitting for a fool to live in luxury – how much worse for a slave to rule over princes! Like snow in summer or rain in harvest, honor is not fitting for a fool (Proverbs 26:1). Principle #3 – Don’t argue with foolish people. Don’t have anything to |
do with foolish and stupid arguments, because you know they produce quarrels. And the Lord’s servant must not quarrel; instead, he must be kind to everyone, able to teach, not resentful (2 Tim. 2:23-24). Principle #4 – Protect yourself from the resentment and anger caused by foolish people. A stone |
is heavy and sand is weighty, but the resentment caused by a fool is heavier than both (Proverbs 27:3 ). Stay away from a foolish man, for you will not find knowledge on his lips (Proverbs 14:7). Are you encouraged here? I personally invite you to subscribe and get the |

- PASSENGER-STRAND (1) (remove) - A large-scale chemical modification screen identifies design rules to generate siRNAs with high activity, high stability and low toxicity (2009) - The use of chemically synthesized short interfering RNAs (siRNAs) is currently the method of choice to manipulate gene expression in mammalian cell culture, yet improvements of siRNA design is expectably required for successful application |
in vivo. Several studies have aimed at improving siRNA performance through the introduction of chemical modifications but a direct comparison of these results is difficult. We have directly compared the effect of 21 types of chemical modifications on siRNA activity and toxicity in a total of 2160 siRNA duplexes. We demonstrate that siRNA activity is primarily enhanced by favouring the |
incorporation of the intended antisense strand during RNA-induced silencing complex (RISC) loading by modulation of siRNA thermodynamic asymmetry and engineering of siRNA 3-overhangs. Collectively, our results provide unique insights into the tolerance for chemical modifications and provide a simple guide to successful chemical modification of siRNAs with improved activity, stability and low toxicity. |
Each year more than 4 million homeless pets are killed as a result of overpopulation, but families who adopt from animal shelters or rescue groups can help preserve these lives and support the growing trend of socially responsible holiday shopping. Best Friends Animal Society encourages families this holiday season to give the precious gift of life by adopting homeless pets rather than buying from |
breeders, pet stores or online retailers. Also, resist the urge to surprise a friend or family member with a living gift. Choosing the right pet is an extremely personal decision, one that should be made carefully by the adults who will be caring for the animal for its 15- to 20-year lifetime. Instead, offer an adoption gift certificate paired with a basket of pet |
care items or stuffed animal for the holiday itself, and then let the person or family choose the actual pet that feels right to them. Once you’ve decided to adopt, keep in mind that welcoming a pet into your life is a big decision and requires important preparation. Best Friends offers tips and advice to help make a smooth transition at home: * Determine |
roles and responsibilities – Before bringing home a new pet, discuss what roles and responsibilities each family member will take on. Who will be in charge of feeding, walks, changing the litter box and taking your pet for regular visits to the vet? Giving each family member a specific task will help everyone feel involved, especially young children. * Prep the house – Adding |
a pet to the house means adding new items to your shopping lists. For dogs, the basics are a collar and leash, chew toys, a kennel and dog bed. Cats need a litter box and litter, a scratching post and a carrying crate for transportation. Also don’t forget food and toys. * Have your pet spayed/neutered – Spaying or neutering is one of the |
greatest gifts you can provide your pet and community. It not only helps control the overabundance of pets, but can also help prevent medical and behavioral problems from developing. Most shelters include this with the adoption package or can recommend a local veterinarian in your area, so check with the staff at the shelter before you leave. * Research community rules and resources – |
Do a little research on what identification (tags, microchips, etc.) you might need for your pet. Scout out the local dog parks and runs for future outdoor fun, and make sure you know where emergency vet clinics or animal hospitals are located. * Set limits – Having pre-determined rules will create consistency in training and help make the home a pleasant environment for you |
and your pet. Will your pet be allowed to snuggle with you in bed or curl up with you on your furniture? Will treats be limited to one a day? It’s important to discuss these questions as a family before your new family member arrives. An estimated 17 million people will be adding pets to their families this year, so this season, help bring |
Taking Play Seriously By ROBIN MARANTZ HENIG Published: February 17, 2008 On a drizzly Tuesday night in late January, 200 people came out to hear a psychiatrist talk rhapsodically about |
play -- not just the intense, joyous play of children, but play for all people, at all ages, at all times. (All species too; the lecture featured touching photos of |
a polar bear and a husky engaging playfully at a snowy outpost in northern Canada.) Stuart Brown, president of the National Institute for Play, was speaking at the New York |
Public Library's main branch on 42nd Street. He created the institute in 1996, after more than 20 years of psychiatric practice and research persuaded him of the dangerous long-term consequences |
of play deprivation. In a sold-out talk at the library, he and Krista Tippett, host of the public-radio program ''Speaking of Faith,'' discussed the biological and spiritual underpinnings of play. |
Brown called play part of the ''developmental sequencing of becoming a human primate. If you look at what produces learning and memory and well-being, play is as fundamental as any |
other aspect of life, including sleep and dreams.'' The message seemed to resonate with audience members, who asked anxious questions about what seemed to be the loss of play in |
their children's lives. Their concern came, no doubt, from the recent deluge of eulogies to play . Educators fret that school officials are hacking away at recess to make room |
for an increasingly crammed curriculum. Psychologists complain that overscheduled kids have no time left for the real business of childhood: idle, creative, unstructured free play. Public health officials link insufficient |
playtime to a rise in childhood obesity. Parents bemoan the fact that kids don't play the way they themselves did -- or think they did. And everyone seems to worry |
that without the chance to play stickball or hopscotch out on the street, to play with dolls on the kitchen floor or climb trees in the woods, today's children are |
missing out on something essential. The success of ''The Dangerous Book for Boys'' -- which has been on the best-seller list for the last nine months -- and its step-by-step |
instructions for activities like folding paper airplanes is testament to the generalized longing for play's good old days. So were the questions after Stuart Brown's library talk; one woman asked |
how her children will learn trust, empathy and social skills when their most frequent playing is done online. Brown told her that while video games do have some play value, |
a true sense of ''interpersonal nuance'' can be achieved only by a child who is engaging all five senses by playing in the three-dimensional world. This is part of a |
larger conversation Americans are having about play. Parents bobble between a nostalgia-infused yearning for their children to play and fear that time spent playing is time lost to more practical |
pursuits. Alarming headlines about U.S. students falling behind other countries in science and math, combined with the ever-more-intense competition to get kids into college, make parents rush to sign up |
their children for piano lessons and test-prep courses instead of just leaving them to improvise on their own; playtime versus r?m?uilding. Discussions about play force us to reckon with our |
underlying ideas about childhood, sex differences, creativity and success. Do boys play differently than girls? Are children being damaged by staring at computer screens and video games? Are they missing |
something when fantasy play is populated with characters from Hollywood's imagination and not their own? Most of these issues are too vast to be addressed by a single field of |
study (let alone a magazine article). But the growing science of play does have much to add to the conversation. Armed with research grounded in evolutionary biology and experimental neuroscience, |
some scientists have shown themselves eager -- at times perhaps a little too eager -- to promote a scientific argument for play. They have spent the past few decades learning |
how and why play evolved in animals, generating insights that can inform our understanding of its evolution in humans too. They are studying, from an evolutionary perspective, to what extent |
play is a luxury that can be dispensed with when there are too many other competing claims on the growing brain, and to what extent it is central to how |
that brain grows in the first place. Scientists who study play, in animals and humans alike, are developing a consensus view that play is something more than a way for |
restless kids to work off steam; more than a way for chubby kids to burn off calories; more than a frivolous luxury. Play, in their view, is a central part |
of neurological growth and development -- one important way that children build complex, skilled, responsive, socially adept and cognitively flexible brains. Their work still leaves some questions unanswered, including questions |
about play's darker, more ambiguous side: is there really an evolutionary or developmental need for dangerous games, say, or for the meanness and hurt feelings that seem to attend so |
