Snapshots of NMDA receptor activation may help in novel drug design

Structural biologists at Cold Spring Harbor Laboratory and Janelia Research Campus/HHMI, have obtained snapshots of the activation of an important type of brain-cell receptor. Dysfunction of the receptor has been implicated in a range of neurological illnesses, including Alzheimer's disease, Parkinson's disease, depression, seizure, schizophrenia, autism, and injuries related to stroke.

ZOTEN nanoparticles can help develop natural immunity against genital herpes

An effective vaccine against the virus that causes genital herpes has evaded researchers for decades. But now, researchers from the University of Illinois at Chicago working with scientists from Germany have shown that zinc-oxide nanoparticles shaped like jacks can prevent the virus from entering cells, and help natural immunity to develop.

Derivatives of female sex hormones can influence natural melanin production, study suggests

When skin cells responsible for pigmentation are exposed to estrogen or progesterone, the cells respond by adjusting their melanin production, resulting in either skin darkening or lightening. Although pregnant women often experience alterations in skin pigmentation, the reason for the changes has long puzzled physicians.

Post-mortem toxicology screening has many phases

Prince's autopsy was conducted by A. Quinn Strobl, MD, FCAP, a member of the College of American Pathologists. The results are expected to take at least two weeks, perhaps as many as six full weeks. This tragedy has people asking again "Why do toxicology results take so long?"

Five simple steps could reduce future life-threatening asthma attacks and hospital admissions

A national care check list (or ‘care bundle’) is launched today for NHS hospitals discharging asthma patients who have recently received treatment for an acute asthma attack.

Researchers reveal how bile component taurine attracts Vibrio cholera

A group of researchers from Osaka University, Hosei University, and Nagoya University have revealed the molecular mechanism that Vibrio cholerae, the etiological agent of cholera, is attracted by bile. This group has also successfully detected the ligand binding to the bacteria chemoreceptor in vivo for the first time. These results may significantly advance research on mechanism and control of V. cholerae.

Brain chemical dopamine plays key role in representing or encoding movement

Princeton University researchers have found that dopamine - a brain chemical involved in learning, motivation and many other functions - also has a direct role in representing or encoding movement. The finding could help researchers better understand dopamine's role in movement-related disorders such as Parkinson's disease.

Lab-grown mini-brains shed light on health crisis posed by Zika virus in fetal brains

Studying a new type of pinhead-size, lab-grown brain made with technology first suggested by three high school students, Johns Hopkins researchers have confirmed a key way in which Zika virus causes microcephaly and other damage in fetal brains: by infecting specialized stem cells that build its outer layer, the cortex.

Exposure to laundry detergent packets more dangerous to young children, study finds

A new study conducted by the Center for Injury Research and Policy of the Research Institute at Nationwide Children's Hospital and the Central Ohio Poison Center found that exposure to laundry detergent packets is more dangerous to young children than exposure to other types of laundry and dishwasher detergent.

Researchers describe how bed bugs break down insecticides

There are many reasons why bed bugs have made a comeback in recent decades, and their resistance to commonly used insecticides is one of the most widely accepted explanations.

Caltech researchers map out pathways of neurons responsible for Parkinson's motor impairments

Because billions of neurons are packed into our brain, the neuronal circuits that are responsible for controlling our behaviors are by necessity highly intermingled. This tangled web makes it complicated for scientists to determine exactly which circuits do what. Now, using two laboratory techniques pioneered in part at Caltech, Caltech researchers have mapped out the pathways of a set of neurons responsible for the kinds of motor impairments--such as difficulty walking--found in patients with Parkinson's disease.

FDA expands campaign to educate rural, white male teens about dangers of smokeless tobacco use

The U.S. Food and Drug Administration announced today it is expanding its award-winning "The Real Cost" campaign to educate rural, white male teenagers about the negative health consequences associated with smokeless tobacco use. For the first time, messages on the dangers of smokeless tobacco use – including nicotine addiction, gum disease, tooth loss, and multiple kinds of cancer – are being highlighted through the placement of advertisements in 35 U.S. markets specifically selected to reach the campaign's target audience.

Well-established optics technique can locate brain tumors within a minute compared to conventional methods

When operating on cancer, surgeons want to remove tumors and not healthy tissue. This is especially important and challenging when dealing with brain tumors, which are often spread out and mixed in with the healthy tissue. Now, researchers have shown that a well-established optics technique can reveal exactly where brain tumors are, producing images in less than a minute -- unlike conventional methods that can take a whole day.

Study describes precise mechanisms that enable TB bacteria to persist in the body

Bacteria that cause tuberculosis trick immune cells meant to destroy them into hiding and feeding them instead. This is the result of a study led by researchers from NYU Langone Medical Center and published online April 18 in Nature Immunology.

Researchers find way to attack a process that tumor cells use to escape effects of cancer drugs

Cancer cells often devise ways to survive even in the presence of toxic chemotherapy. Now, a research team led by investigators at Beth Israel Deaconess Medical Center has found a way to attack a process that tumor cells use to escape the effects of standard cancer drugs. The discovery is published online today in the journal Nature Cell Biology.
