NBA Finals: Warriors’ comeback ability faces ultimate test

first_imgOAKLAND – Can the Warriors come back? That’s become a familiar and jarring question as they’ve trailed by double digits for six consecutive games.That comeback curiosity now goes for the Warriors’ three-peat hopes in the NBA Finals.As much as injury woes are impacting this two-time title defense, the Warriors constantly find themselves in need of a rally.They’ve trailed by 17, 18, 17, 12, 12 and 17 dating back to Game 2 of the Western Conference Finals against Portland. And, yet, they are …last_img read more

Molecular Motors Put a Spring in Your Step

first_imgWhen you feel in spring in your step, thank tiny molecular motors in your muscles and tissues that make it possible.A paper in Science by researchers primarily from University of Washington, Seattle, proposed the novel idea that the molecular motors in muscle cells store elastic energy.  Observing flight muscles in moths, they deduced that the springiness of these motors provides an additional boost to the power generate by muscles:Muscles not only generate force. They may act as springs, providing energy storage to drive locomotion. Although extensible myofilaments are implicated as sites of energy storage, we show that intramuscular temperature gradients may enable molecular motors (cross-bridges) to store elastic strain energy…. These results suggest that cross-bridges can perform functions other than contraction, acting as molecular links for elastic energy storage.Researchers from Europe, publishing in PNAS, found that collagen and fibrin exhibit non-linear strain response upon loading.  This is another factor that provides resilience in movement.We show that the nonlinear mechanical response of networks formed from un–cross-linked fibrin or collagen type I continually changes in response to repeated large-strain loading. We demonstrate that this dynamic evolution of the mechanical response arises from a shift of a characteristic nonlinear stress–strain relationship to higher strains. Therefore, the imposed loading does not weaken the underlying matrices but instead delays the occurrence of the strain stiffening. Using confocal microscopy, we present direct evidence that this behavior results from persistent lengthening of individual fibers caused by an interplay between fiber stretching and fiber buckling when the networks are repeatedly strained…. Thus, a fibrous architecture in combination with constituents that exhibit internal plasticity creates a material whose mechanical response adapts to external loading conditions.This behavior is so interesting, they pass the news on to biomimetics engineers: “This design principle may be useful to engineer novel materials with this capability.”Once again, the CEH Law is confirmed: Darwin-talk is inversely proportional to the amount of detail discussed about biological systems.

Khoisan couple home at last

first_imgThe Khoisan or Bushmen people werethe subjects of degrading study andscrutiny in the 19th and early 20thcenturies, often stemming from Europe. The traditional Khoisan way of life is thesedays practised by fewer people.

They found that the Pienaars had been kept at the Imperial Academy of Sciences before removal to the Natural History Museum in Vienna.But the South African government viewed them as citizens, and worked with the Austrian government for four years to reach an agreement to bring the Pienaars’ remains back to their land of birth.Coming home at lastSpeaking to reporters after receiving the remains, Mashatile described the return of the Khoisan couple as a significant milestone.“It is particularly a triumph over oppression,” he said. “They will now rest in peace among their people.”The minister said the couple will be given proper re-burial amongst their people in the Northern Cape next month.“We’ve reached an agreement with the Pienaar family, the Northern Cape provincial government, and the Khoisan community that the reburial should be conducted in the second week of May.”Mashatile said the Austrian government relinquished the remains three days before the flight home. A delegation of Khoisan people performed a ceremony at the National History Museum in Vienna upon receiving the couple.One of the couple’s direct granddaughters, Francis Pienaar, said that although her grandparents’ graves were exhumed in Danielskuil near Kuruman, as a family they have not yet decided where the re-burial will take place.“We are extremely excited and we don’t know how we can thank our government,” she said.Restoring dignityAccording to Rassool, the Natural History Museum and Vienna University’s Institute of Anthropology still hold the remains of some 50 South Africans and the partial remains of about 150 more – but because the Pienaars’ names had been discovered and subsequently their place of origin, it was possible to bring them back.However, efforts will begin to repatriate the others as well.Northern Cape MEC for social development, Alvin Botes, said people of the Northern Cape viewed the repatriation of the Pienaars’ remains as dear efforts by the government.“We are looking forward to giving the couple a proper re-burial and from now on, we are saying our human dignity should be respected and none of our graves should be opened or exhumed without our permission,” he said.The operation is part of the government’s efforts to restore dignity to the victims of colonialism and racism. In January 2002, Sarah Baartman‘s remains were returned to South Africa, which put an end to the many years of exploitation she endured abroad.last_img read more

Bengal BJP president’s vehicle attacked

first_imgAt least seven persons were injured in an attack on West Bengal BJP president Dilip Ghosh’s vehicle in Purba Medinipur district on Monday. Mr. Ghosh alleged that supporters of the Trinamool Congress were behind the attack. “Since the Trinamool Congress is unable to tackle us politically, they are targeting us with brute force,” said Mr. Ghosh. The BJP leader was visiting the district to attend a BJP meeting. He was shown black fags and stones were thrown at his car, damaging its windows. The attack was carried out near Contai bus stand. Some media persons who reached the spot to report the violence were also injured. Several motorbikes, which were part of Mr. Ghosh’s cavalcade, were also attacked. TMC leader and MP from the district Dibyendu Adhikari denied any involvement of the State’s ruling party in the violence. “The clash was a result of factionalism in the BJP. The party members are fighting over the post of district office-bearers,” he said.last_img read more
