Like about four years ago, the name of Grigoriy Yakovlevich (Grisha) Perelman is again in the mass-media headlines all around the world.
Grisha is a prominent mathematician, who was able to solve one of the most perplexed mathematical problems of the last two centuries: he had managed to prove the Poincaré conjecture.
In 2006 he was awarded the prestigious
Fields Medal, but had voluntarily and expressly refused to accept it.
Most recently, he has been awarded the not less prestigious
Clay Millenium Prize, but is expected to reject this award as well.
It makes me very happy when I see new precise results on the mass of the top quark being produced by the CDF collaboration (to which I still proudly belong). CDF, one of the two hadron collider experiments operating at the 2-TeV Tevatron proton-antiproton synchrotron in Batavia, IL, has been measuring the top quark mass since 1994, one year prior to its discovery. The figure with the top candidates (histogram) from which the mass measurement of 174+-12 GeV was obtained in 1994 is shown on the right below; backgrounds and top expectation are shown by hatched lines.
Rocket science, it isn't: eating at restaurants is typically a more caloric experience than if you prepare foods at home.
1However, the new health care law has a provision that may help customers make more informed choices about the calorie content of their food. The law requires that any restaurant chain with at least 20 outlets post calorie counts for all the food items they sell. This affects about 200,000 restaurants nationwide, WSJ
reports. The general idea is that it could help consumers make decisions that will change their behavior and lead to more healthy eating habits.
Utah's red rocks have yielded a rare skeleton of a new species of plant-eating dinosaur, Seitaad ruessi, that lived 185 million years ago and may have been buried alive by a collapsing sand dune.
The discovery confirms the widespread success of sauropodomorph dinosaurs during the Early Jurassic Period, researchers say. The finding is documented this week in PLoS One
People who stay mentally sharp into their 80s and beyond challenge the notion that brain changes linked to mental decline and Alzheimer's disease are a normal, inevitable part of aging, say scientists presenting at the ACS National Meeting.
The researchers say that elderly people with super-sharp memory — so-called "super-aged" individuals — somehow escaped formation of brain "tangles." The tangles consist of an abnormal form of a protein called "tau" that damages and eventually kills nerve cells. Named for their snarled, knotted appearance under a microscope, tangles increase with advancing age and peak in people with Alzheimer's disease.
Specially medicated contact lenses loaded with vitamin E can keep glaucoma medicine near the eye — where it can treat the disease — almost 100 times longer than possible with current commercial lenses, scientists reported today at the ACS National Meeting.
Glaucoma is second only to cataracts as the leading cause of vision loss and blindness in the world. It affects almost 67 million people. Eye drops that relieve the abnormal build-up of pressure inside the eye that occurs in glaucoma, are a mainstay treatment.
Protein phosphorylation, the process by which proteins are flipped from one activation state to another, is a crucial function for most living beings, since it controls nearly every cellular process, including metabolism and gene transcription.
Consumers could soon be paying a lot more for meat, milk, eggs and other farm staples
if bad weather withers a U.S. corn crop that is now tethered to grain-intensive renewable fuel mandates, a new University of Illinois study warns.
A corn shortage, coupled with surging demand to meet government-ordered ethanol standards, could push cash prices to $7 a bushel, the study found, squeezing livestock producers and spiking grocery prices. The study warns that federal policymakers need to forge solutions now to cushion the blow of a shortfall that history shows is a matter of when and how severe, not if.
A new study published in Neuron suggests that our ability to respond with outrage toward people who attempt to harm us is seated in a brain region called the ventromedial prefrontal cortex (VMPC).
Patients with damage to this brain area are unable to conjure a normal emotional response to hypothetical situations in which a person tries, but fails, to kill another person. Therefore, they judge the situation based only on the outcome, and do not hold the attempted murderer morally responsible.
The findings support the idea that making moral judgments requires at least two processes — a logical assessment of the intention, and an emotional reaction to it.
