'Big Bang Theory' gets shout out to Nobel Prize announcementLife imitated art Tuesday when "The Big Bang Theory" — the American TV sitcom, not the scientific explanation for how the universe began — entered the annals of Nobel Prize history. The announcement of the winners of this year's Nobel in physics began with a nod to an unlikely cultural reference: the opening lyrics to the show's theme song. "The Big Bang Theory" had its finale in May. In the episode, two of the main characters, Sheldon and Amy, win the physics prize.


A research team reports that combining a type of radiation therapy with immunotherapy not only cures pancreatic cancer in mice, but appears to reprogram the immune system to create an 'immune memory' in the same way that a vaccine keeps the flu away. The result is that the combination treatment also destroyed pancreatic cells that had spread to the liver, a common site for metastatic disease.

When you're sleep deprived, you reach for doughnuts and pizza. A new study has figured out why you crave more calorie-dense, high-fat foods after a sleepless night. Blame it on your sleepy nose -- or olfactory system. First, it goes into hyperdrive, sharpening the food odors for the brain. But then there is a breakdown in communication with brain areas that receive food signals. Then decisions about what to eat change.

A new study offers an explanation for how ''protocells'' could have emerged on early Earth, eventually leading to the cells we know today. The work suggests that molecules called cyclophospholipids may have been the ingredient necessary for protocells to form important internal structures called vesicles, which likely kicked off the evolutionary process.

(LONDON) — Hundreds of climate change activists camped out in central London on Tuesday during a second day of world protests by the Extinction Rebellion movement to demand more urgent actions to counter global warming.

Determined activists glued themselves to the British government’s Department of Transport building as police working to keep streets clear appealed to protesters to move to Trafalgar Square.

Cities in Australia, elsewhere in Europe and other parts of the world also had climate change protests for a second day.

British Prime Minister Boris Johnson appealed Monday to the protesters to stop blocking London’s streets. He called the activists “uncooperative crusties” who should abandon their “hemp-smelling bivouacs.”

Mike Gumn, 33, a National Health Service manager with two children, said he used a day of annual leave so he could attend the demonstration. Gumn, of Bristol, took umbrage at Johnson’s characterization of climate change activists as “hippies.”

“I want to make a statement that (the activists) are all different sorts of people from all different walks of life, not just people you would call hippies,” he said.

Police arrested 152 people on Monday, taking the two-day total to 471.

Disruption continued in other major cities in Europe. Activists set up tents in Paris, occupying a major square and blocking traffic along a bridge near city hall.

“We’ll stay here until the end and if they must remove us by carrying us out, moving us out or using teargas, we will be here, we will remain united, non-violent,” said Clement Schneider, 26, from Fribourg, Switzerland.

“And this will only reinforce, I hope, our commitment for the coming protests.”

In Brisbane, Australia, protesters chained themselves to intersections in the city center and three people locked themselves onto barrels filled with concrete. A protester hanging from a harness beneath Brisbane’s Story Bridge and brandishing “climate emergency” flags was taken into police custody and charged with unregulated high-risk activity.

Queensland police confirmed 29 people – ranging in age from 19 to 75 – were arrested in the city, and six others were arrested in Sydney after lying in a downtown street intersection.

More than 100 protesters dressed as bees at Sydney’s Hyde Park to highlight their claim that insects are under threat due to the impact of humans on the environment.

Some activists camped at Melbourne’s Carlton Gardens overnight before marching to a street corner locked down by more than 100 protesters in inclement weather. Police arrested 59 people for blocking an intersection.

“I don’t know that shutting the city down necessarily wins you many friends,” Victoria premier Daniel Andrews said.

In Perth, about 50 protesters converged outside the offices of The West Australian, the city’s daily newspaper. The front page of Tuesday’s paper was left intentionally blank for protesters to use as a placard.

Founded in Britain last year, Extinction Rebellion has chapters in some 50 countries and wants to achieve net zero carbon emissions by 2025.

On Monday, activists with the movement stopped traffic in European cities and smeared themselves and emblems of Wall Street in fake blood and lay in New York streets.

In Berlin, 300 people blocked Potsdamer Platz, placing couches, tables, chairs and flowerpots on the road. They earlier set up a tent camp outside German Chancellor Angela Merkel’s office out of dissatisfaction with her government’s climate policy.

Merkel’s chief of staff, Helge Braun, criticized the group’s tactics.

“We all share an interest in climate protection, and the Paris climate targets are our standard in this,” he told ZDF television. “If you demonstrate against or for that, that is OK. But if you announce dangerous interventions in road traffic or things like this, of course that is just not on.”

Like entrance and exit doors on a building, a cell's outer surface has doors -- channels, pumps, and transporters that selectively control what molecules enter or exit. In the immune system, T cells possess unique sets of 'doors', including ones that specialize in calcium ion movement. Now, researchers describe a unique mechanism for coordinating these calcium entrance and exit 'doors' on T cells that helps them carry out their jobs and ensure normal immune function.
