A View of Clouds of Cosmic Dust in the Region of Orion

A New Image From the APEX Telescope Shows Clouds of Cosmic Dust in the Region of Orion

This new image from the APEX telescope in Chile shows the region around the reflection nebula NGC 1999 in visible light, with the APEX observations overlaid in brilliant orange tones that seem to set the dark clouds on fire. A new image from the Atacama Pathfinder Experiment (APEX) telescope in Chile shows a beautiful view […]

UCLA Researchers Image Abnormal Brain Proteins in Retired NFL Players

A New Technique May Lead to Earlier Diagnosis of Brain Disorders in Athletes

Using a brain-imaging tool developed for assessing neurological changes associated with Alzheimer’s disease, researchers at UCLA have identified the abnormal tau proteins associated with sports-related concussions and mild traumatic brain injuries in five retired National Football League players. Sports-related concussions and mild traumatic brain injuries have grabbed headlines in recent months, as the long-term damage […]

Study Shows That TRPA1 is Essential in the Skin’s Response to UVA Light

The Skins Response to UVA Light

Researchers at Brown University discovered that human melaoncyte skin cells rely on an ion channel called TRPA1 to allow a flood of calcium ions, which signal the cell to begin making melanin, into the cells when they are exposed to UVA light. Providence, Rhode Island – Brown University – Last year, a team of researchers […]

Herschel Views Red Supergiant Star Betelgeuse

An Image of the Red Supergiant Star Betelgeuse

This new image from Herschel’s Photodetecting Array Camera and Spectrometer (PACS) shows the red supergiant star Betelgeuse, which is located in the Orion Constellation and appears to be on a collision course with a dusty “wall.” Multiple arcs are revealed around Betelgeuse, the nearest red supergiant star to Earth, in this new image from ESA’s […]

Artificial Enzyme Reveals Never Before Seen Structure

A Biological Catalyst Capable of Joining Two Segments of RNA

A newly published study details how researchers turned an ordinary protein into an artificial enzyme, a biological catalyst capable of joining two segments of RNA. Five years ago, a pair of researchers used a clever update on a technique called in vitro evolution – evolution in a test tube – to turn an ordinary protein […]

DARPA’s New Cyber Targeted-Attack Analyzer Program

DARPAs New Cyber Targeted Attack Analyzer Program

DARPA’s new Cyber Targeted-Attack Analyzer program looks at how information is connected and moves to uncover and prevent targeted attacks without a human having to direct it. The Department of Defense (DoD) maintains one of the largest computer networks in the world. The network follows DoD personnel across the globe collecting, transferring and processing information […]

“TFIID” Can Co-Exist in Two Distinct Structural States

A Critical Transcription Factor Coexists in Two Distinct States

Using single-particle cryo-electron microscopy, a team of scientists from the Berkeley Lab have shown that the transcription factor known as “TFIID” can co-exist in two distinct structural states. The enormously diverse complexity seen amongst individual species within the animal kingdom evolved from a surprisingly small gene pool. For example, mice effectively serve as medical research […]

Astronomers Believe a Gamma-Ray Burst Hit Earth in the 8th Century

An 8th Century Gamma Ray Burst

Astronomers from the Royal Astronomical Society suggest that two compact stellar remnants, such as black holes or neutron stars, collided and released a large gamma ray burst that hit the Earth in the 8th century and is responsible for the high levels of the isotope Carbon-14 and Beryllium-10 found in tree rings formed in 775 […]

Sunken Wood Can Develop into Habitats for Microorganisms and Invertebrates

Wood Can Develop into Oases for Deep Sea Life

Scientists from the Max Planck Institute have shown how sunken wood can develop into attractive habitats for a variety of microorganisms and invertebrates due to the activity of bacteria, which produce hydrogen sulfide during wood degradation. Trees do not grow in the deep sea, nevertheless sunken pieces of wood can develop into oases for deep-sea […]

Ancient DNA Reveals Link between Early Humans & Present-Day Asians and Native Americans

Humans Living 40000 Years Ago in Beijing Are Related to Many Present Day Asians and Native Americans

Analyses of ancient DNA, which had been extracted from the leg bone of an early modern human living some 40,000 years ago near Beijing, revealed that this early modern human was related to the ancestors of many present-day Asians and Native Americans. An international team of researchers including Svante Pääbo and Qiaomei Fu of the […]

Study Suggests Auroras Occur Outside Our Solar System

Auroras Can Occur Outside Our Solar System

New research from the University of Leicester suggests that processes similar to those which power Jupiter’s auroras could be responsible for radio emissions detected from a number of objects outside our solar system. University of Leicester planetary scientists have found new evidence suggesting auroras – similar to Earth’s Aurora Borealis – occur on bodies outside […]

Scientists Turn HIV Against Itself, A Possible Step Towards a Cure

Protection from HIV 1 Infection in Human CD4 T Cells

By turning HIV against itself, researchers at the Queensland Institute of Medical Research have demonstrated the ability to stop HIV replication in a laboratory environment. A Queensland Institute of Medical Research scientist has developed a way to use HIV to beat HIV in the laboratory. Associate Professor David Harrich, from QIMR’s Molecular Virology Laboratory, has […]
