Experimental Small Molecule Shows Potential in Preventing Meth Relapse
Experimental Small Molecule Preventing Meth Relapse
2017/4/27
New research from The Scripps Research Institute (TSRI) suggests that the reason methamphetamine users find it so hard to quit—88 percent of them relapse, even after rehab—is that meth takes advantage...

Today, Popular Science magazine and the National Science Foundation (NSF) announce the winners of the 15th Annual Vizzies Challenge, celebrating the use of visual media to artfully and clearly communi...
The complex structures making the surface of a virus are small weaves of proteins that make a big impact on how a virus interacts with cells and its environment. A slight change in protein sequence ma...
Portland State research shows some viruses can infect even after major mutations
Portland State research some viruses infect
2017/3/30
Portland State University researchers have found that only about half the genes in a specific virus affecting single cell organisms is needed to infect a host. This means the virus can undergo major m...

Snake bit UCI chemists easily and cheaply halt venom’s spread
2017/3/30
Chemists at the University of California, Irvine have developed a way to neutralize deadly snake venom more cheaply and effectively than with traditional anti-venom – an innovation that could spare mi...
干细胞研究揭示寨卡病毒如何引发小头症
干细胞研究 寨卡病毒 引发小头症
2017/2/21
近年来，巴西等美洲国家频发新生儿小头症。科学界已证实寨卡病毒感染与小头症发病存在关联，却不清楚病毒怎样影响胎儿脑部发育。德国研究人员日前表示，他们已经找到寨卡病毒导致小头症的科学证据。德国科隆大学医学院等机构研究人员在新一期《细胞—干细胞》杂志上报告说，他们将健康人的皮肤细胞“重新编程”，培养成诱导多能干细胞，进而培养出神经前体细胞。神经前体细胞可分化出多种神经细胞，可谓脑部发育的“起点”。

加拿大学者发现朊病毒蛋白结构为治疗疯牛病等带来曙光
加拿大学者 朊病毒蛋白结构 疯牛病
2016/11/1
加拿大阿尔伯塔大学开展的一项开创性研究表明，他们发现了传染性朊病毒蛋白的结构，该结构长期以来是一个谜团。朊病毒蛋白可导致疯牛病、鹿和麋鹿的慢性消耗性疾病（又称疯鹿病）和人的克雅氏病。朊病毒蛋白是一种结构异常折叠的蛋白质，非常难以被提纯和研究。这种蛋白自1980年代首次被提纯以来，由于它的不溶性和聚集倾向，不能用标准的结构生物学技术来研究，研究人员对其结构仅有有限的认识，难以清楚阐明。
