A proposed regulation would codify a legal opinion in 2017 that declared the 'incidental' killing of birds during the course of business as no longer subject to punishment.
The danger of having artificially intelligent machines do our bidding is that we might not be careful enough about what we wish for. The lines of code that animate these machines will inevitably lack nuance, forget to spell out caveats, and end up giving AI systems goals and incentives that don't align with our true preferences. A now-classic thought experiment illustrating this problem was posed
As the final sliver of daylight faded over the Capitol dome last night, it was clear that Democrats' long, frustrated quest for a deus to save them from Donald Trump would produce no machina after all. Instead there was only Rep. Adam Schiff, the party's tireless point man in the impeachment trial, who stood in the well of the Senate making an 11th-hour argument that Trump's political-dirt-for-mi

Now, researchers at Princeton University present evidence of Neanderthal ancestry in African populations too, and its origin provides new insights into human history.
Neanderthal DNA sequences may be more common in modern Africans than previously thought, and different non-African populations have levels of Neanderthal ancestry surprisingly similar to each other, finds a study publishing Jan. 30 in the journal Cell. Researchers arrived at these findings by developing a new statistical method, called IBDmix, to identify Neanderthal sequences in the genomes of mo
Several US states have considered doing away with the practice of changing the clocks forward or back in favor of permanent Daylight Saving Time (DST), while experts around the world suggest permanent Standard Time is a better alternative for health and wellbeing. A study appearing Jan. 30 in the journal Current Biology puts forth evidence of another downside of DST: it increases the risk of fatal
Parasitic worms date back thousands of years, causing diseases that limit human potential. But today, effective treatment against them requires just a few pills, taken once or twice a year. With 1.7 billion people at risk of infection, Ellen Agler and her team at the END Fund are imagining a world without disease caused by worms. Learn about how they're seeking to lower treatment costs, amplify pr
Yesterday afternoon, Pete Buttigieg found himself on the receiving end of a good old-fashioned ratioing —that quantifiable flood of Twitter rage when a bad take elicits far more (negative) replies than likes or retweets. The backlash likely took the Buttigieg campaign by surprise, given that the tweet in question might have seemed like anodyne boilerplate at first glance. In the face of unprecede
Varför inte börja med en legobit? Var kommer den ifrån och vilka barn får leka med den? Mer invecklad än så behöver inte hållbar utveckling vara – åtminstone i det första skedet.

Journalists writing about science have become more science fluent over the past 20 years, but the need to be first and the practice of giving equal exposure to opposing views regardless of scientific evidence (e.g. climate change) has been detrimental to the public's understanding of the facts. Reporting on science from the "frontier" doesn't provide the full picture because it doesn't give scien
During the past decade, the gene editing tool CRISPR has transformed biology and opened up hopeful avenues to correct deadly inherited diseases. Last fall, scientists began the first human clinical trials using CRISPR to combat diseases like cancer. They remove some of a person's cells, CRISPR edit the DNA, and then inject the cells back in, where hopefully, they will cure the disease.

Give John Bolton his due. By writing a book that apparently corroborates the core argument of those seeking to impeach and remove President Donald Trump, the former national security adviser has shown genuine moral courage. The literature on moral courage helps explain why: It's because Bolton is an ideological fanatic. His fervent belief in supporting America's allies and confronting its adversa

A new study from the Smidt Heart Institute at Cedars-Sinai and other centers nationwide shows that patients who underwent a minimally invasive transcatheter aortic-valve replacement (TAVR), had similar key 5-year clinical outcomes of death and stroke as patients who had traditional open-heart surgery to replace the valve.
Tohoku University geophysicist Toshio Suga collaborated with climate physicist Ryohei Yamaguchi of Korea's Pusan National University to investigate how upper-ocean stratification has changed over a period of 60 years.
The literature of synthetic chemistry is large, and it goes back well over a century. Those of us who know the field sometimes despair of the state that literature is in – it can be pretty messy – but we really shouldn't. It's actually far more orderly than many other fields, and it has a lot of aspects that make it intrinsically more "organizable", not least the backbone of chemical structures t

What if solar cells worked at night? That's no joke. In fact, a specially designed photovoltaic cell could generate up to 50 watts of power per square meter under ideal conditions at night, about a quarter of what a conventional solar panel can generate in daytime, according to a recent concept article.
Even more detailed insights into the cell will be possible in future with the help of a new development: Scientists have succeeded in accelerating a hundred thousand-fold the nuclear magnetic resonance (NMR) method for investigating RNA.

Here, we use the boron isotopic composition ( 11 B) of biogenic calcium carbonate to investigate the extent to which organisms' ability to regulate pH at their site of calcification (pH CF ) determines their calcification responses to
To be optimally effective, peptide-based vaccines need to be administered with adjuvants. Many currently available adjuvants are toxic, not biodegradable; they invariably invoke adverse reactions, including allergic responses and excessive inflammation. A nontoxic, biodegradable, biocompatible, self-adjuvanting vaccine delivery system is urgently needed. Herein, we report a potent vaccine deliver
CCR9 + T cells have an increased potential to be activated and therefore may mediate strong antitumor responses. Here, we found, however, that CCL25, the only chemokine for CCR9 + cells, is not expressed in human or murine triple-negative breast cancers (TNBCs), raising a hypothesis that intratumoral delivery of CCL25 may enhance antitumor immunotherapy in TNBCs. We first determined whether this
Mimicking the cellular environment, metal-organic frameworks (MOFs) are promising for encapsulating enzymes for general applications in environments often unfavorable for native enzymes. Markedly different from previous researches based on bulk solution synthesis, here, we report the synthesis of enzyme-embedded MOFs in a microfluidic laminar flow. The continuously changed concentrations of MOF p
Biodiversity's contribution to human welfare has become a key argument for maintaining and enhancing biodiversity in managed ecosystems. The functional relationship between biodiversity ( b ) and economic value ( V ) is, however, insufficiently understood, despite the premise of a positive-concave bV relationship that dominates scientific and political arenas. Here, we review how individual links
Plant-microbe interactions are mediated by signaling compounds that control vital plant functions, such as nodulation, defense, and allelopathy. While interruption of signaling is typically attributed to biological processes, potential abiotic controls remain less studied. Here, we show that higher organic carbon (OC) contents in soils repress flavonoid signals by up to 70%. Furthermore, the magn
Perforin-2 (MPEG1) is thought to enable the killing of invading microbes engulfed by macrophages and other phagocytes, forming pores in their membranes. Loss of perforin-2 renders individual phagocytes and whole organisms significantly more susceptible to bacterial pathogens. Here, we reveal the mechanism of perforin-2 activation and activity using atomic structures of pre-pore and pore assemblie
Viral infections kill millions of people and new antivirals are needed. Nontoxic drugs that irreversibly inhibit viruses (virucidal) are postulated to be ideal. Unfortunately, all virucidal molecules described to date are cytotoxic. We recently developed nontoxic, broad-spectrum virucidal gold nanoparticles. Here, we develop further the concept and describe cyclodextrins, modified with mercaptoun
Women harboring heterozygous germline mutations of BRCA2 have a 50 to 80% risk of developing breast cancer, yet the pathogenesis of these cancers is poorly understood. To reveal early steps in BRCA2 -associated carcinogenesis, we analyzed sorted cell populations from freshly-isolated, non-cancerous breast tissues of BRCA2 mutation carriers and matched controls. Single-cell whole-genome sequencing
Artificial rotary molecular motors convert energy into controlled motion and drive a system out of equilibrium with molecular precision. The molecular motion is harnessed to mediate the adsorbed protein layer and then ultimately to direct the fate of human bone marrow–derived mesenchymal stem cells (hBM-MSCs). When influenced by the rotary motion of light-driven molecular motors grafted on surfac
To uncover the genetic basis of anthracycline-induced cardiotoxicity (AIC), we recently established a genetic suppressor screening strategy in zebrafish. Here, we report the molecular and cellular nature of GBT0419 , a salutary modifier mutant that affects retinoid x receptor alpha a (rxraa) . We showed that endothelial, but not myocardial or epicardial, RXRA activation confers AIC protection. We
Self-propelling micromotors are emerging as a promising micro- and nanoscale tool for single-cell analysis. We have recently shown that the field gradients necessary to manipulate matter via dielectrophoresis can be induced at the surface of a polarizable active ("self-propelling") metallodielectric Janus particle (JP) under an externally applied electric field, acting essentially as a mobile flo
We demonstrate direct eddy covariance (EC) observations of methane (CH 4 ) fluxes between the sea and atmosphere from an icebreaker in the eastern Arctic Ocean. EC-derived CH 4 emissions averaged 4.58, 1.74, and 0.14 mg m –2 day –1 in the Laptev, East Siberian, and Chukchi seas, respectively, corresponding to annual sea-wide fluxes of 0.83, 0.62, and 0.03 Tg year –1 . These EC results answer conc
Artificial control of animal locomotion has the potential to simultaneously address longstanding challenges to actuation, control, and power requirements in soft robotics. Robotic manipulation of locomotion can also address previously inaccessible questions about organismal biology otherwise limited to observations of naturally occurring behaviors. Here, we present a biohybrid robot that uses onb
Researchers discovered an additional component in ATP synthase, a molecular machine that produces the energy-conserving compound. They obtained a first-ever high-resolution structure of the C ring from spinach chloroplasts. As the 3D computer model of it was taking shape, the biophysicists spotted additional circle-shaped elements inside the C ring.While the discovery is interesting in and of itse
Nitrogen is one of the most important nutrients as is a key component for healthy crop production globally. Because the microbiota is crucial to the plant's ability to take in nitrogen, scientists are very interested in identifying ways to ensure this transfer.
Researchers at the National Institute of Standards and Technology (NIST) and their colleagues have for the first time created and imaged a novel pair of quantum dots — tiny islands of confined electric charge that act like interacting artificial atoms. Such "coupled" quantum dots could serve as a robust quantum bit, or qubit, the fundamental unit of information for a quantum computer.
The next time you're thinking about whether to cook dinner or order a pizza for delivery, think of this: Plants have been doing pretty much the same thing for eons.
Dogs that are smaller, younger, non-neutered, or live in U.S. counties with high opioid prescription rates are at higher risk of being the subjects of phone calls about accidental opioid poisoning to a poison control center. Mohammad Howard-Azzeh and colleagues at the University of Guelph, Ontario, present these findings in the open-access journal PLOS ONE on January 29, 2020.
