SAN FRANCISCO — Two weeks after closing a $44 billion deal to buy Twitter, Elon Musk painted a bleak financial picture for the social media company and outlined a series of changes for employees in his first companywide emails to staff.

In two emails sent to workers late on Wednesday, Mr. Musk said the economy was challenging. He added that he planned to end Twitter’s remote work policy and wanted employees to renew their focus on generating revenue and fighting spam.

“Sorry that this is my first email to the company, but there is no way to sugarcoat the message,” Mr. Musk, 51, wrote in one email. “The economic picture ahead is dire.” Twitter was too heavily dependent on advertising and vulnerable to pullbacks in brand spending, he added, and would need to bolster the revenue it gets from subscriptions.

Building A More Secure World — Dr. James Revill, Ph.D. — Head of Weapons of Mass Destruction & Space Security Programs, UNIDIR, UN Institute for Disarmament Research United Nations.


Dr. James Revill, Ph.D. (https://unidir.org/staff/james-revill) is the Head of the Weapons of Mass Destruction (WMD) and Space Security Program, at the UN Institute for Disarmament Research (UNIDIR).

Dr. Revill’s research interests focus on the evolution of the chemical and biological weapons and he has published widely in these areas. He was previously a Research Fellow with the Harvard Sussex Program at the Science Policy Research Unit, University of Sussex and completed research fellowships with the Landau Network Volta Center in Italy and the Bradford Disarmament Research Centre in the UK.

Dr. Revill holds a Ph.D. focused on the evolution of the Biological Weapons Convention from the University of Bradford, UK.

Dr. Revill’s areas of expertise include biological weapons, biosecurity, bioterrorism, chemical weapons, chemical terrorism, chemical weapons convention, compliance, verification, and improvised explosive devices.

Cancer research – and its impact on patient care – has made some significant strides in just the last 10 years. For example, the availability and affordability of sequencing genetic information has improved greatly – meaning researchers and doctors are now better able to get information about a person’s risk for certain cancers as well as what drugs might work best for cancer patients. Another major leap forward came with the approval of vaccines that help prevent infections from the human papilloma virus (HPV) that cause cervical cancers. Many other advances have occurred in the areas of targeted therapy, immunotherapy, and cancer screening technology.

Still, cancer remains a massive health problem that researchers across the United States and elsewhere are working tirelessly to solve. Many experts are hopeful that they can build on decades of learning and recent advances to move even more rapidly toward reducing the cancer burden.

We invited 10 American Cancer Society Research Professors to share their perspectives and predictions for how cancer research will evolve over the next 10 years – and what this might mean for patients. These 10 experts are among the very best in their field; the Society’s Research Professor grants are awards that go to a select group – researchers and doctors who have made seminal contributions that have changed the direction of basic, clinical, psychosocial, behavioral, health policy or epidemiologic cancer research.

Is solar geoengineering an alternative solution to the climate crisis?

Solar geoengineering is a branch of geoengineering that focuses on reflecting sunlight back into outer space to reduce global warming. There are several solar geoengineering techniques being researched; the most feasible one consists of spraying reflective aerosols in the stratosphere.

Scientists also consider brightening marine clouds to make them more reflective.

Recently, the White House’s Office of Science and Technology Policy launched a five-year research plan to investigate methods for reflecting solar radiation back to outer space in an attempt to reduce the effects of global warming.

There is a mix of excitement and fear and lots of memes.

After much back and forth and a lawsuit, four days ago, Elon Musk completed his $44 billion takeover of the social media platform Twitter. Musk had put the deal on hold after his initial offer earlier this year. Later he backed out, citing a high number of fake or spam accounts on the platform, a point that then-CEO Aggarwal had publicly denied.

Musk was then taken to court by Twitter’s lawyers. The court had given the two parties time till the month’s end to work out a deal.

As soon as Musk acquired Twitter, he proceeded to fire CEO Parag Aggarwal, finance executive Ned Segal, and legal and policy executive Vijaya Gadde.


Billionaire CEO Elon Musk has finally bought Twitter after a long saga of back-and-forth negotiations and even a lawsuit. The internet is both excited and afraid, and people are expressing their opinions in all kinds of ways.
