Y-type stars

Brown dwarf stars are failed stars. Their masses are so small, less than about eighty Jupiter-masses, that they lack the ability to heat up their interiors to the roughly ten million kelvin temperatures required for normal hydrogen burning (hydrogen burning fuels the Sun, whose surface temperature is about 5700 kelvin).

Astronomers track the birth of a 'super-Earth'

A new model giving rise to young planetary systems offers a fresh solution to a puzzle that has vexed astronomers ever since new detection technologies and planet-hunting missions such as NASA's Kepler space telescope have revealed thousands of planets orbiting other stars: While the majority of these exoplanets fall into a category called super-Earths—bodies with a mass somewhere between Earth and Neptune—most of the features observed in nascent planetary systems were thought to require much more massive planets, rivaling or dwarfing Jupiter, the gas giant in our solar system.

NASA probe successfully peers into Jupiter's Great Red Spot

A NASA spacecraft, Juno, has successfully peered into the giant storm raging on Jupiter, known as the Great Red Spot, and its first pictures should be out in days, the US space agency said Tuesday.

Distant galaxies 'lift the veil' on the end of the cosmic dark ages

Astronomers studying the distant Universe have found that small star-forming galaxies were abundant when the Universe was only 800 million years old, a few percent of its present age. The results suggest that the earliest galaxies, which illuminated and ionized the Universe, formed at even earlier times.

Hidden stars may make planets appear smaller

In the search for planets similar to our own, an important point of comparison is the planet's density. A low density tells scientists a planet is more likely to be gaseous like Jupiter, and a high density is associated with rocky planets like Earth. But a new study suggests some are less dense than previously thought because of a second, hidden star in their systems.

Using sensors and social networks to make slopes safer

The peace and quiet that envelope a lone hiker on a leaf-riddled trail or a rock climber perched on the top of a cliff seem a world away from the noise of a social media feed. But Department of Mechanical Engineering (MechE) alumnus Jim Christian SM '14 had an idea to tap into the superabundance of social-media data to benefit athletes and outdoor adventurers. He, along with MIT Sloan School of Management alumnus Brint Markle MBA '14, created a device that could help determine avalanche risk. Their device has led to a network in which people can upload and share critical real-time information about the conditions—including avalanche risk—on a particular slope or mountain.

Asimov's Laws won't stop robots harming humans, so we've developed a better solution

How do you stop a robot from hurting people? Many existing robots, such as those assembling cars in factories, shut down immediately when a human comes near. But this quick fix wouldn't work for something like a self-driving car that might have to move to avoid a collision, or a care robot that might need to catch an old person if they fall. With robots set to become our servants, companions and co-workers, we need to deal with the increasingly complex situations this will create and the ethical and safety questions this will raise.

Remotely controlling electronic devices with hand gestures

Moving things with a wave of the hand: thanks to Empa technology this dream could soon become real. A sensor made of piezo-resistive fibers integrated in a wristband measures wrist movements and converts them into electrical signals.

Human pose estimation for care robots using deep learning

Expectations for care robots are growing against the backdrop of declining birthrates, an aging population, and a lack of care staff. As an example, for care at nursing homes and other such facilities, it is anticipated that robots will check the condition of the residents while patrolling the facility. When evaluating a person's condition, while an initial estimation of the pose (standing, sitting, fallen, etc.) is useful, most methods to date have utilized images. These methods face challenges such as privacy issues, and difficulties concerning application within darkly lit spaces. As such, the research group (Kaichiro Nishi, a 2016 master's program graduate, and Professor Miura) has developed a method of pose recognition using depth data alone (Fig. 1).

The research was conducted at the National Eye Institute (NEI), part of the National Institutes of Health.

In rats that can't control glutamate, cocaine is less rewarding, staving off relapse

Rats missing a neuroreceptor that controls the release of the neurotransmitter glutamate are less amenable to the rewarding effects of cocaine, increasing their chance of kicking the habit once addicted, researchers from the National Institute on Drug Abuse (NIDA) find. Their work, appearing July 11 in Cell Reports, suggests that the receptor, which protects nerve cells from fatal inundation by excess glutamate, is involved in modulating the reward-seeking behavior associated with drug addiction.

New method shortcut in drug development

JFK's back problems—a new look

"Camelot," the term used to describe the John Fitzgerald Kennedy (JFK) presidency after JFK's death, conjures up an image of youth and vigor, an image the 35th president of the U.S. promoted of himself as a young, healthy, strong-bodied man. But this image belies the truth: that Kennedy had been plagued by illnesses and discomfort since he was a small child and required strong medication to perform his tasks as president.

Researchers identify visual system changes that may signal Parkinson's disease

Changes in the visual systems of newly diagnosed Parkinson's disease patients may provide important biomarkers for the early detection and monitoring of the disease, according to a new study published online in the journal Radiology.

Preeclampsia: New study documents its enormous economic and health burden

Preeclampsia, a dangerous condition that may occur during pregnancy, can lead to serious complications for both mother and baby. Driven in part by older maternal age and greater obesity, rates of preeclampsia are rising rapidly, yet surprisingly there are few national estimates of the health and economic impact of preeclampsia on mothers and their infants. A new study in the American Journal of Obstetrics and Gynecology (AJOG) provides sobering data on this topic by examining the short-term costs associated with the condition. Significantly increasing the chance of adverse health outcomes, preeclampsia accounts for over $2.18 billion of health care expenditure in the first 12 months after birth.

Reduced mastication results in the impairment of memory and learning function

Recently, frequency of mastication has dramatically decreased along with changes in dietary habits. Masticatory stimulation has particular influence on the development of the central nervous system as well as the growth of maxillofacial tissue in children. Recently, deterioration of masticatory function due to aging and the consequent reduction of brain function have become major problems. Although the relationship between mastication and brain function is potentially important, the mechanism underlying is not fully understood.

How your risk of heart disease stems back to your time in the womb

Caregiving needs increase as older adults approach the end of life

Dying adults in the United States have 2.5 people assisting them, on average, according to a new study. Yet those caring for adults at the end-of-life, especially spouses, are likely to report that they have no one assisting them and no time for themselves. Researchers at Icahn School of Medicine at Mount Sinai have found that dying adults received almost twice as many hours of help per week compared to those not at the end of life, and that end-of-life caregivers were significantly more likely to report physical difficulty related to giving care. Their analysis was published today in the July issue of Health Affairs.

Structural insights into the modulation of synaptic adhesion by MDGA for synaptogenesis

Synapses connected by various synaptic adhesion molecules are communication spaces between neurons for transmitting information. Among various synaptic adhesion molecules, neuroligins are arguably the most widely studied class of postsynaptic adhesion molecules, which mainly interact with presynaptic neurexins to induce excitatory or inhibitory synapse development. Recently, the membrane-associated mucin (MAM) domain-containing GPI anchor protein 1 (MDGA1) has been characterized as a key suppressor of Neuroligin-2/Neurexin-1β-mediated inhibitory synapse development, but how it acts remains a mystery.

Pulse rate monitoring before a C-section can improve maternal health

Doctors often prescribe preventative drugs to women who are to receive spinal blocks while giving birth via a Caesarean section. This is done to ensure that they do not experience a severe drop in blood pressure. Such preventative treatment against hypotension, however, can have side-effects, both for the mother and her baby. In a study in Springer's journal Annals of Biomedical Engineering, Augusto Navarro of the Miguel Servet University Hospital in Spain and collaborators investigate how clinicians can use aspects of pulse rate to decide whether blood pressure medication should be provided.

Faster diagnosis of inherited and lethal nerve disease could advance search for new treatments

Johns Hopkins physicians report success in a small study of a modified skin biopsy that hastens the earlier diagnosis of an inherited and progressively fatal nerve disease and seems to offer a clearer view of the disorder's severity and progression. With a quicker and less invasive way to visualize the hallmark protein clumps of the rare but lethal disease—familial transthyretin amyloidosis—the researchers say they hope to more rapidly advance clinical trials of treatments that may slow the disease and extend patients' lives.

Treatment rapidly reverses the effect of blood thinner dabigatran

At least 28 million prescriptions for blood thinners are filled by pharmacists yearly for the irregular heartbeat of atrial fibrillation, deep vein thrombosis, and other indications, according to the Department of Health and Human Services. However, on rare occasions, anticoagulants can present risks of accidental bleeding and hemorrhage or can delay emergency surgery. A newly completed phase III clinical study demonstrates the safety and efficacy of idarucizumab, a novel therapy that acts as an antidote to the blood thinner dabigatran.

Researchers discover evolutionary origin of redox regulation in plants

During the development of higher life forms over the course of millions of years, there have always been significant and comparatively sudden leaps in development. As a consequence, living organisms developed new skills and conquered additional habitats. In this process they adopted these abilities partly from their predecessor organisms: For example the plastids of the plants, the place where photosynthesis takes place, were originally autonomous unicellular living organisms.

Dolphins follow the trawlers
