Greys Anatomy season 17 release date: Will there be another series of Greys Anatomy? – Express

Will there be another series of Greys Anatomy?

Hit medical drama Greys Anatomy brought its 16th season to a close on Thursday, April 9 on ABC.

The finale tied up some loose ends as viewers found out more about Richard Webbers (played by James Pickens Jr) fate.

However, the episode will also leave many viewers wondering whether the show will be returning again with season 17.

Fans of the long-running medical drama should rejoice as the next outing has already been confirmed.

The series was actually renewed before season 16 even began airing on ABC last year.

In May 2019, it was confirmed Meredith Grey star Ellen Pompeo renewed her contract and how seasons 16 and 17 were both renewed at once.

After the renewal, Pompeo told People: Obviously I never anticipated the show still being the number one show on the network. How do you walk away from a hit?

The fans will dictate when the show ends. As much as we think were in control, were not.

Its the fans show at this point. They control how long the show goes. Well see. I kind of just take it year by year and see.

The new season of Greys Anatomy is expected to air in its usual new season slot in September.

This is when the returning show usually starts their new seasons and has been when every outing apart from series one of Greys Anatomy has aired.

However, it seems possible season 17 may be delayed due to the impact of coronavirus COVID-19 on the television production industry.

The series has already been impacted by this with production shutting down back in March, leaving this season at 21 episodes rather than 25.

Showrunner Krista Vernoff addressed this on Twitter back on March 28, hinting how the story would continue in season 17.

She wrote: We are disappointed that we dont get to complete our storytelling this season.

The good news? 1621 plays like a satisfying finale! Its not where we planned to end, but its beautiful & the questions that linger we will answer next year.

This could mean the series delays its premiere into 2021 if work is halted on the new series beginning.

Express.co.ukwill update this article as soon as any more information is released.

Greys Anatomy airs on Thursdays on ABC.

Virus-infected honey bees more likely to gain entrance to healthy hives | Illinois – University of Illinois News

CHAMPAIGN, Ill. Honey bees that guard hive entrances are twice as likely to allow in trespassers from other hives if the intruders are infected with the Israeli acute paralysis virus, a deadly pathogen of bees, researchers report.

Their new study, reported in the Proceedings of the National Academy of Sciences, strongly suggests that IAPV infection alters honey bees behavior and physiology in ways that boost the viruss ability to spread, the researchers say.

The most important finding of our study is that IAPV infection increases the likelihood that infected bees are accepted by foreign colonies, said Adam Dolezal, a professor of entomology at the University of Illinois at Urbana-Champaign who led the new research. Somehow, the infected bees are able to circumvent the guards of foreign colonies, which they shouldnt be able to do.

Honey bees touch their mouthparts and antennae together to share food and information, but the practice also can transmit viruses.

Previous studies have shown that IAPV-infected honey bees are more likely than healthy bees to lose their way when returning home from foraging trips. In commercial beekeeping operations where hives are stacked much closer together than in the wild, the virus is even more likely to spread from one infected colony to nearby healthy ones.

To capture the behavior of individual bees, researchers tagged each one with the equivalent of a QR code and continuously monitored their interactions. The scientists were able to simultaneously track the behaviors of as many as 900 bees.

In previous work, study co-author U. of I. entomologist Gene Robinson and his colleagues developed this automated system to study bees engaged in trophallaxis, a process by which honey bees exchange regurgitated food and other liquids. They used this system to study how IAPV infection might affect the bees trophallaxis social network.

Honey bees use trophallaxis to share food with each other as well as hormones and other signaling molecules that can affect their physiology and behavior. They do it in pairs by touching their mouthparts and antennae, and each bee does this with hundreds of partners a day, said Robinson, who directs the Carl R. Woese Institute for Genomic Biology at Illinois. Trophallaxis is essential to the spread of information and nutrition throughout the hive, but unfortunately, a behavior performed with such close social contact also allows viral infections to be transmitted through a hive.

In the new study, the scientists saw that honey bees altered their behavior in response to infection in their own hives. IAPV-infected bees and bees that had had their immune systems stimulated to mimic infection engaged in less trophallaxis than their healthy counterparts did.

Researchers tagged each honey bee with the equivalent of a QR code and used an automated system to study trophallaxis, a process by which the bees exchange regurgitated food and other liquids. The system allowed them to track how infection with IAPV affected the bees trophallaxis social network.

The infected bees were just as mobile as the other bees, so their lower rates of trophallaxis were not the result of sluggishness from being sick, Dolezal said. The researchers believe this change in behavior is a general response to a health threat and not specific to IAPV infection, which is in line with previous research.

When the scientists placed honey bee workers at the entrance of a foreign hive, however, the infected bees engaged in more trophallaxis with the guards, the researchers found. The guards were more likely to admit them than to let in healthy bees or bees whose immune systems had been stimulated. This response was specific to IAPV infection.

Something about them must be different, Dolezal said.

To test whether the IAPV-infected bees were giving off a different chemical odor than their healthy nest mates, the researchers analyzed the chemistry of the hydrocarbons that coat the bees exoskeletons. They discovered distinct hydrocarbon profiles for healthy bees, IAPV-infected bees and immunostimulated bees.

It seems that the virus is changing how the bees smell, and perhaps the infected bees also are behaving in a way that is meant to appease the guards by engaging more in trophallaxus, Dolezal said.

The new findings suggest that IAPV is evolving in ways that enhance its ability to infect as many hosts as possible, Dolezal said.

If youre a virus, its much more valuable to get transmitted to a new family group, like traveling from one city to a new city, he said. And so how do you get there? You increase the chances that the sick bees leaving colony A are more likely to get into colony B.

The Christopher Family Foundation, National Academies Keck Futures Initiative, American Pollinator Protection Campaign and U.S. Department of Agricultures National Institute of Food and Agriculture supported this research.

UAB Department of Cell, Developmental and Integrative Biology ranks fourth in nation for NIH funding – The Mix

The ranking measured 79 anatomy/cell biology departments in U.S. medical schools.

The Department of Cell, Developmental and Integrative Biology at the University of Alabama at Birmingham continues its rise in the top tier of U.S. anatomy/cell biology departments.

The departments 2019 National Institutes of Health funding of $16,479,206 is ranked No. 4 in the nation out of 79 anatomy/cell biology basic science departments, according to a newly released report. Marcas Bamman, Ph.D., professor in the UAB CDIB department (pronounced see-dib), had the third highest NIH funding out of 821 principal investigators in the anatomy/cell biology departments, with funding of $6,600,693. Bamman is director of the UAB Center for Exercise Medicine.

While being ranked fourth is exciting and well deserved, said Brad Yoder, Ph.D., professor and chair of CDIB, I think the most important thing to recognize is that this is really a reflection of the exciting, innovative and impactful research that the faculty in CDIB are directing and that our trainees are performing. CDIB is one of the basic science departments in the UAB School of Medicine.

Two other CDIB researchers were in the top 100 in NIH funding in 2019, with more than $1 million Yoder and Qin Wang, M.D., Ph.D., a CDIB professor. Fourteen other CDIB researchers had NIH funding in 2019, that averaged $464,000.

In 2017, CDIB ranked 14th in NIH funding, and in 2018, the department ranked ninth, according to annual reports of NIH funding compiled by the Blue Ridge Institute for Medical Research.

The research excellence of the CDIB department is partly the fruit of a 2012 merger of two former basic medical science departments at UAB.

Brad Yoder, Ph.D., Qin Wang, M.D., Ph.D., and Marcas Bamman, Ph.D.That merger between the former Department of Cell Biology and the Department of Physiology and Biophysics is really one of the major strengths that has contributed to our growth and high performance, Yoder said. We have a highly collegial and collaborative faculty with highly diverse research programs that span from very basic studies of how proteins fold and move around a cell, or how cells communicate with each other, to clinical studies that have direct impact on human health. This diversity has brought groups together to work on common biological problems from very different perspectives.

This interdisciplinary collaboration supports one of the pillars of UABs strategic plan, Forging the Future the pillar of research, innovation and economic development.

At the time of the merger, UAB President Ray Watts, M.D., who was then the medical school dean, said, The basic sciences cell biology, physiology, microbiology, pharmacology, toxicology and neurobiology are where breakthroughs in cancer, heart disease and neurological disorders often begin. The new department will leverage existing strengths of two faculties to help us move even faster toward the development of new treatments.

At UAB, Bamman holds the University of Alabama Health Services Foundation School of Medicine Endowed Professorship in Regenerative and Translational Medicine, and Yoder holds the University of Alabama Health Services Foundation Endowed Chair in Biomedical Research.

April: Corticosteroid drugs and adrenal gland | News and features – University of Bristol

New research by academics at the University of Bristol has found evidence that prolonged treatment of synthetic corticosteroid drugs increases adrenal gland inflammation in response to bacterial infection, an effect that in the long-term can damage adrenal function.

Synthetic corticosteroid drugs are widely prescribed to treat many inflammatory and autoimmune diseases but taking a high dose over a long period of time can cause adverse side effects. Patients undergoing prolonged corticosteroid treatment can also develop adrenal insufficiency, which in rare occasions can lead to adrenal gland failure.

Previous studies have concentrated on studying the long-term effects of corticosteroid treatment on the hypothalamus and pituitary but have not looked at the direct effects that these steroids may have on the adrenal gland.

In this study, published in Brain, Behavior, and Immunity, the research team tested the hypothesis that synthetic corticosteroids cause long-term changes in the adrenal gland steroidogenic pathways that are responsible for adrenal suppression.

The research found that the rhythms of glucocorticoid secretions are disrupted following prolonged treatment with synthetic corticosteroid drugs, and that the adrenal steroidogenic pathway is directly affected. Importantly, these changes persist long after discontinuation of the treatment.

The study also showed a pro-inflammatory effect of synthetic glucocorticoids treatment in the adrenal gland. This is an important finding with high clinical relevance as intra-adrenal activation of the immune system can affect adrenal functionality by interfering with the steroidogenic pathway, damaging adrenal endothelial microvascular cells, and by inducing apoptosis and reducing cell viability.

Dr Francesca Spiga, Honorary Research Fellow in the Bristol Medical School: Translational Health Sciences (THS) and corresponding author, said: "Our study provides valuable insights on the regulation of the adrenal steroidogenic pathway that are important starting points for future studies on adrenal gland physiology.

"Importantly, our research builds on our knowledge of the mechanisms through which corticosteroid drugs induce adrenal insufficiency, by showing simultaneous effects within multiple pathways involved in steroidogenesis, including circadian clock genes and inflammation pathways.

"A more detailed understanding of the effects of synthetic glucocorticoids on glucocorticoid hormones dynamics and on adrenal steroidogenic activity and the identification of mechanisms regulating these effects, will help develop better treatments that will improve patient care."

Future studies should address whether adrenal insufficiency, and its effects, can be prevented by using synthetic corticosteroid drugs that more closely resemble endogenous glucocorticoids in term of effectiveness and plasma half-life.

Endogenous glucocorticoids (cortisol in humans, corticosterone in rodents) regulate many physiological functions, including metabolism, cardiovascular tone, reproduction, mood and cognition, and the immune system. Clinical therapy with high doses of synthetic corticosteroids results in adrenal insufficiency, characterised by adrenal atrophy and decreased basal and stress-induced cortisol secretion, that may persist for several years after therapy withdrawal. One of the pathological consequences of adrenal insufficiency is the potential development of an adrenal crisis resulting from decreased cortisol secretion in response to inflammatory stressors such as infections, injuries and major surgery.

The study was funded by a Medical Research Council programme grant.

The Big O: Who has it better? – The Big Smoke Australia

One Australian study has reached a climax in deciding who experiences the best orgasm. I need a cigarette.

We dont need a formal study to know that the arousal process differs significantly for men and women but when it comes to the actual orgasm, whose experience is better? This age-old question is on everybodys lips at the moment, so we peeled back the cover on some global research from AsapSCIENCEto see if we could arouse a definitive answer as to Who has a better orgasm males or females?

What we immediately learned from our deep dive into the Big O was that there are many similarities in how those fireworks actually feel for men and women. For example, researchers asked college students of both genders to explain how an orgasm feels. After removing any words that specifically referred to genitalia, they were left with an orgy of very similar words, suggesting that males and females feel a very similar experience during their apogee. This may be because irrespective of whether you stand or sit to pee, an identical physiological process occurs in both genders in order for that climax to occur.

Another similarity is the ability of both men and women to enjoy multiple orgasms. Due to these little beauts typically lacking a refractory period, they have long been identified as womens only business; however, in recent times it has been discovered that men can also enjoy in these repeated pleasures. Historically, male orgasms were thought only to occur simultaneously with ejaculation, but research has confirmed that before or after ejaculation, men are capable of non-ejaculatory orgasms.

AsapSCIENCE also identified that post-O, both men and women experience a distinct feeling of drowsiness, which is attributed to a surge in the hormone called prolactin.

Now, interestingly, if you have a busy schedule planned post-coitus, then you may like to consider finishing yourself off because science has shown that four times the amount of that drowsy-inducing hormone is released after intercourse, compared to the amount released after an orgasm achieved via masturbation.

By now youre forgiven for thinking that perhaps males and females do have a similar experience when it comes to climactic fervour. However, lets now take a quick perve at the differences.

A national Australian study exploring heterosexual sex found that women tend to experience orgasms less often than men (69% versus 95% of all sexual encounters), but when they do get there, the actual climax itself goes for longer (20+ seconds for females versus 3 to 10 seconds for males).

Interestingly, the type of sex youre engaging in was also found to contribute to your climactic experience. For example, one study revealed that while the rate of orgasm among straight and gay men was similar, the rate of orgasm for women varied significantly by sexual orientation.

Straight women reportedly have around 12% fewer orgasms than gay women; 25% of who indicated they climaxed in 100% of instances. Whats more, 50% of gay women suggested they orgasmed in more than 75% of their sexual encounters. And if thats not enough to make you admire the tribe, lesbians were found to engage in sex for an average duration of 30 to 45 minutes, compared to a meagre 15 to 30 minutes of sexual activity by straight women.

Whether women will or wont get there was also found to be influenced by genetics, with one study involving twins suggesting that the genetic makeup of women can predict one-third of the likelihood of whether or not she will climax during sex.

Of course, when you think about it, men and women are physiologically designed to have similar experiences, and the orgasm is no exception. Being part of your partners orgasm typically enhances your own climactic experience, and this is no coincidence. We need to be able to understand and relate to each other, in order for emotional connections to occur.

So there you have it; the bare naked facts, all laid out. But who has the upper hand in the orgasm stakes?

From an evolutionary perspective, we are all designed to enjoy the moment, and physiologically speaking, the process to ensure an orgasm occurs is identical in both men and women.

The bottom line is, that while differences definitely exist for males and females during those OMG moments, these discrepancies are most likely due to individual factors such as psychology, anatomy and physiology. The best thing you can do to ensure your endings are always as happy as they can possibly be, is to know how best to please yourself, and then let your partner in on the secrets.

Can Rats AI Rats, That is Shed Light on How Neural Networks Work? – HPCwire

Rats have long been highly-valued model organisms helping researchers better understand biology and pursue drug development. Now, researchers from Harvard and DeepMind say AI-versions of rats can help humans better understand how AI neural networks learn and develop and how their counterparts in real life work. An interesting account of their work appear on IEEE Spectrum today.

Heres brief excerpt from the article written by Edd Gent:

[A]uthors ofa new paperdue to be presented this week at theInternational Conference on Learning Representationshave created a biologically-accurate 3D model of a rat that can be controlled by a neural network in a simulated environment. They also showed that they could use neuroscience techniques foranalyzing biological brain activityto understand how the neural net controlled the rats movements.

The platform could be the neuroscience equivalent of a wind tunnel, saysJesse Marshall, co-author and postdoctoral researcher at Harvard, by letting researchers test different neural networks with varying degrees of biological realism to see how well they tackle complex challenges.

Typical experiments in neuroscience probe the brains of animals performing single behaviors, like lever tapping, while most robots are tailor-made to solve specific tasks, like home vacuuming, he says. This paper is the start of our effort to understand how flexibility arises and is implemented in the brain, and use the insights we gain todesign artificial agents with similar capabilities.

Its a fascinating idea. The researchers built the AI rat model (muscles, joints, vision, movement. Etc.) based on observing real rats and then trained a neural network to guide the rat through four tasksjumping over a series of gaps, foraging in a maze, trying to escape a hilly environment, and performing precisely-timed pairs of taps on a ball.

As the rats improved at the tasks the researchers were abler to watch the controlling neural networks develop. Its early work, and the researchers agree that because they built the model much of what they learned was expected. One interesting insight, though, was that the neural activity seemed to occur over longer timescales than would be expected if it was directly controlling muscle forces and limb movements, according to Diego Aldarondo, a co-author and graduate student at Harvard.

He is quoted in the article, This implies that the network represents behaviors at an abstract scale of running, jumping, spinning, and other intuitive behavioral categories, he says, a cognitive model that has previously been proposed to exist in animals. This kind of work, says the researchers, will help understand both how neural networks evolve and also provide insight into how biology neural networks work.

Study Reveals New Role of Astrocytes in Brain Function | Neuroscience – Sci-News.com

Astrocytes play a direct role in the regulation of neuronal circuits involved in learning and memory, according to new research from Baylor College of Medicine and M.D. Anderson Cancer Center.

Huang et al reveal region-specific transcriptional dependencies for astrocytes and identify astrocytic NFIA as a key transcriptional regulator of hippocampal circuits. Image credit: Huang et al, doi: 10.1016/j.neuron.2020.03.025.

Astrocytes are star-shaped glial cells in the brain and spinal cord.

They have unique cellular, molecular and functional properties and outnumber neurons by over fivefold. They occupy distinct brain regions, indicating regional specialization.

There is evidence suggesting that transcription factors proteins involved in controlling gene expression regulate astrocyte diversity.

A team led by Professor Benjamin Deneen from Baylor College of Medicine looked to get a better understanding of the role transcription factor NFIA, a known regulator of astrocyte development, played in adult mouse brain functions.

The researchers worked with a mouse model they had genetically engineered to lack the NFIA gene specifically in adult astrocytes in the entire brain.

They analyzed several brain regions, looking for alterations in astrocyte morphology, physiology and gene expression signatures.

We found that NFIA-deficient astrocytes presented defective shapes and altered functions, Professor Deneen said.

Surprisingly, although the NFIA gene was eliminated in all brain regions, only the astrocytes in the hippocampus were severely altered. Other regions, such as the cortex and the brain stem, were not affected.

Astrocytes in the hippocampus also had less calcium activity calcium is an indicator of astrocyte function as well as a reduced ability to detect neurotransmitters released from neurons.

NFIA-deficient astrocytes also were not as closely associated with neurons as normal astrocytes.

Importantly, all these morphological and functional alterations were linked to defects in the animals ability to learn and remember, providing the first evidence that astrocytes are to some extent controlling the neuronal circuits that mediate learning and memory.

Astrocytes in the brain are physically close to and communicate with neurons. Neurons release molecules that astrocytes can detect and respond to, Professor Deneen said.

We propose that NFIA-deficient astrocytes are not able to listen to neurons as well as normal astrocytes, and, therefore, they cannot respond appropriately by providing the support needed for efficient memory circuit function and neuronal transmission. Consequently, the circuit is disrupted, leading to impaired learning and memory.

The findings were published online in the journal Neuron.

Forming New Habits in the Era of the Coronavirus – ScienceBlog.com

With the coronavirus pandemic upon us, people are readily forming new habits, such as washing their hands more frequently and communicating with colleagues over video platforms like Zoom. Which of these habits will stick when the pandemic is over and which will pass?

Colin Camerer, the Robert Kirby Professor of Behavioral Economics and the T&C Chen Center for Social and Decision Neuroscience Leadership Chair in the Tianqiao and Chrissy Chen Institute for Neuroscience at Caltech, is looking into this question of habit formation, or what scientists call habitization. He says that the coronavirus pandemic may have ripple effects that lead to lasting behavioral changes in the arenas of public health, education, and more.

Camerer is apioneer in the field of behavioral economics, which combines economics, psychology, and neuroscience to better understand the choices people make. For example, in 2018, he and his colleagues performeda study showing that people prefer somewhere between eight and 15 choiceswhen it comes to making shopping decisions; more than that, and they experience what psychologists call choice overload.

Now, Camerer has turned his attention to the habits people are forming in the midst of the coronavirus outbreak. We spoke with him about these habits, if they will persist, and his plans for future studies.

When people get up in the morning, for the first five minutes, they do things that are very routine. They may go to the refrigerator and look for some iced tea or make coffee. Thats when the motor system is taking over for the brain, and you have a habit. The habits are saving time and energy. For instance, right now because of the coronavirus, people are washing their hands more than they ever did before. This may become even more habitized in the future. Youll go to the bathroom or the kitchen and see soap, or a sanitizer dispenser when youre at an airport, and the sight of those things will act as what we call a cue. Its basically classical conditioning. Youll see that cue and think, Oh, in the past, when I saw that cue, I washed my hands. It can be very automatic.

Fighting the virus on the front lines is critically important, but its also relevant to think about changing behaviors. Take the washing-hands example. People have come to understand in this pandemic that the regular flu kills a lot of people, and these are mostly the same types of people who are vulnerable to COVID-19: older people and those with weakened immune systems. For decades, doctors have been saying, Please wash your hands at home and after you shake hands, etc. Its essentially the same advice we are receiving for COVID-19. If people become habitized to hand washing more regularly in the future, this could save a lot of lives from the flu for many years into the future. Of course, this is just speculation at this point, but it is something we want to look into further.

In general, our team is planning to do research on what gets habitized and what doesnt. There often are unintended consequences or ripple effects from outbreaks like this. We want to know if there are positive spillover effects of behavior that we should have been doing all along. Funding agencies like the NSF [National Science Foundation] and NIH [National Institutes of Health] realize this and know that changing behavior is an important part of the equation.

There is always a big social science behavior component with outbreaks. With AIDS, we saw behavioral changes, such as people wearing condoms and programs for needle exchanges. Studying these behavioral patterns is important because its about public health and, ideally, addressing them can be cheaper and more effortless than using financial incentives.

We also want to look at education at the college level. Universities, including Caltech, have transitioned to online learning, which has many advantages. Students can watch lectures online whenever they want, and when theyre most attentive and not sleepy or stressed, and they can press rewind. I think that going forward a lot of professors will adopt a flipped classroom model, where they will make videos for their lectures and use the classroom for discussion. Weve already seen that, in many cases, students like this better. The open question we want to look at is: What habits formed during this pandemic will continue into the physical classroom?

I think a lot of knowledge work, for example writing jobs or those in law and tech, will move to telecommuting. If you ask people what makes them happy and unhappy and what drives them crazy, the worst things are losing a job, losing a spouse, and other obvious things that are really terrible. If you ask about everyday things, youll hear a lot of people complain about commuting. They want to be able to work from home. The big fear for a lot of businesses in letting people work at home is that they think people will sit in their pajamas and goof off. And theres often somebody in an organization who resists the change.

But now the change has been forced upon us. Companies will realize telecommuting is actually a valuable perk, and employees are happier and efficient. This is called forced experimentation. Forced experiments have a benefit for behavioral economists, because they let us ask questions: Are there things we should have been doing before that, if forced to try now, will make a really, really big difference in how we work and live and teach?

Ill tell you a story thats a small bit of evidence that there are better ways to do things or better routines that people dont always explore. There was a study about the London subway, the Tube. Its a huge sprawling system, and lots of people commute on the Tube in the morning. The Tube workers went on strike because they didnt think they were treated well, but the strike was only 48 hours and only took place on part of the Tube system.

From a scientific point of view, this is a natural experiment: you can look at what happened to the people who commuted during the strike areas where there were no trains running and the people had to find a different train route to get to work, and you can compare them to people who, on the same days, could keep their regular commute. The result of this forced experiment was that 5 percent of the workers found a slightly better commute.

The whole point of a habit is that youre on autopilot, you dont try out new things. But trying out new things can be beneficial.
