Barbara K. Kennedy, Penn State University 23 February 2014 — Two teams have independently discovered that a single regulatory protein acts as the master genetic switch that triggers the development of male and female sexual forms (termed gametocytes) of the malaria parasite, solving a long-standing mystery in parasite biology with important implications for human health. The protein, AP2-G, is necessary for activating a set of genes that initiate the development of gametocytes -- the...

Critical Protein For Healthy Cell Growth In Mammals Discovered
2014-01-28 12:37:01

Penn State University A team of researchers from Penn State University and the University of California has discovered a protein that is required for the growth of tiny, but critical, hair-like structures called cilia on cell surfaces. The discovery has important implications for human health because lack of cilia can lead to serious diseases such as polycystic kidney disease, blindness and neurological disorders. "If we want to better understand and treat diseases related to cilium...

Wildlife Greatly Impacted By Arctic Sea-Ice Loss
2013-08-02 07:11:40

April Flowers for redOrbit.com - Your Universe Online Because sea ice is at its lowest point in 1,500 years, scientists are questioning how ecological communities in the Arctic will be affected by this continued and perhaps accelerating melting process over the next two decades. An international team of scientists, led by Penn State University biologist Eric Post, examined relationships among algae, plankton, whales, and terrestrial animals such as caribou, arctic foxes, and walrus, as...

Alzheimer's, Schizophrenia, and Autism Studied With Mature Brain Cells Reprogrammed From Skin Cells
2013-06-07 07:36:57

Pennsylvania State University Difficult-to-study diseases such as Alzheimer's, schizophrenia, and autism now can be probed more safely and effectively thanks to an innovative new method for obtaining mature brain cells called neurons from reprogrammed skin cells. According to Gong Chen, the Verne M. Willaman Chair in Life Sciences and professor of biology at Penn State University and the leader of the research team, "the most exciting part of this research is that it offers the promise of...

Gene Offers New Clues To Treatments For Deep-vein Thrombosis
2013-05-08 09:16:22

Penn State University A gene associated with both protection against bacterial infection and excessive blood clotting could offer new insights into treatment strategies for deep-vein thrombosis -- the formation of a harmful clot in a deep vein. The gene produces an enzyme that, if inhibited via a specific drug therapy, could offer hope to patients prone to deep-vein clots, such as those that sometimes form in the legs during lengthy airplane flights or during recuperation after major...

On Twitter, Anti-vaccination Statements Spread More Easily Than pro-vaccination Statements
2013-04-05 09:39:14

Penn State On Twitter, a popular microblogging and social-networking service, statements about vaccines may have unexpected effects -- positive messages may backfire, according to a team of Penn State University researchers led by Marcel Salathé, an assistant professor of biology. The team tracked the pro-vaccine and anti-vaccine messages to which Twitter users were exposed and then observed how those users expressed their own sentiments about a new vaccine for combating...

Fluorescent Tags Help Scientists Solve Mystery Of Human DNA Replication
2013-04-02 05:24:54

redOrbit Staff & Wire Reports - Your Universe Online Scientists at Penn State University have discovered how a vital step in the human DNA replication process — the loading of molecular structures known as sliding clamps onto DNA molecules — is performed. The researchers say their work, the results of which were published in Tuesday´s edition of the journal eLife, will help uncover some of the mystery surrounding this crucial part of the chemical replication...

New Research Suggests Climate Change Effect On Plant Communities Is Buffered By Large Herbivores
2013-02-20 15:00:34

Penn State Can existing ecological communities persist intact as temperatures rise? This is a question of increasing relevance in the field of climate change and is the focus of a new study to be published in the journal Proceedings of the Royal Society of London on 20 February. The study suggests that the answer to this question may have as much to do with the biological interactions that shape communities as with the effects of climate change itself. The study's insights are based on...


Word of the Day
attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.'
