• Liver tumor growth in mice slowed with new chemo-immunotherapy treatment

  28-02-2017 19:11
  Hepatocellular carcinoma is the most common form of liver cancer, but treatment options are limited and many patients are diagnosed in late stages when the disease can't be treated. Now, researchers have developed a new treatment that combines chemotherapy and immunotherapy to significantly slow tumor growth in mice. The researchers believe that with more research, the strategy could be translated to benefit patients with the disease.

• New approach to treating Alzheimer's disease

  28-02-2017 19:10
  Researchers have introduced a new approach to treat Alzheimer's disease. Alzheimer's disease is the sixth leading cause of death among in older adults. The exact causes of Alzheimer's disease are still unknown, but several factors are presumed to be causative agents. Among these, the aggregation of amyloid-? peptide has been implicated as a contributor to the formation of neuritic plaques, which are pathological hallmarks of Alzheimer's disease.

Scientists named the new species Ramadapis sahnii and said that it existed 11 to 14 million years ago. It is a member of the ancient Sivaladapidae primate family, consumed leaves and was about the size of a house cat.

• Existence of a new quasiparticle demonstrated

  28-02-2017 14:42
  How do molecules rotate in a solvent? Answering this question is a complicated task since the rotation is perturbed by a large number of surrounding atoms, requiring large-scale computer simulations which are sometimes infeasible. Now, scientists have proven that angulons -- quasiparticles he proposed two years ago -- do in fact form when a molecule is immersed in superfluid helium. This offers a quick and simple description for rotation of molecules in solvents.
